The Group integrated the requirements from SMPTE and ATSC into the document „Requirements
for the carriage of metadata and descriptions over MPEG-2 Systems‟ (N3745). Adequate wording
was found for all the requirements from SMPTE and ATSC. Due to lack of time the work was not
yet started.

m6399           Valentim, Nunes, Ducla-Soares, Pereira - IST MPEG-4 Video Compliant
        Framework
This contribution showed that MPEG-4 Conformance is not enough to test the Profile/Level
combinations to their full complexity. This was found undesirable, but also hard to change at this
point in time. The Requirements group adopted 3.1.6, expressing its concern.

m6439      3GPP TSG-SA WG4 - liaison on MPEG-4 Conformance Points (SC 29 N
     3846)
   After discussions, the following answer to 3GPP was written:
MPEG is sympathetic towards 3GPP’s requests, and shares the desire to create an interoperability
point that can be used across content for mobile devices and other content types.

MPEG is willing to define such a conformance point, and in doing so to accommodate all the
restrictions suggested by 3GPP, including the QCIF form factor, even though this is somewhat in
conflict with the MPEG-4 design philosophy. MPEG does, however, greatly value the hierarchy
between Simple and Advanced Simple, and therefore wants to impose an additional restriction. This
restriction does not impact the decoder at all, and in fact decoders will become simpler and
cheaper to implement. It implies a modified decision criterion in the encoder, however. MPEG is
willing to work with you on understanding the implications of this extra restriction.

m6651      Alshaykh, et. al.- Request for a New Level of Simple Scalable for Wireless
     Devices




                                                   26
The description of the market for Simple Scalable Market is understood, and the requirements for
this market as well.
The Requirements group does, however, not want to break hierarchy, as would happen when two
types of scalability would be allowed in L0. Level 1 only allows one type at the time.
About the request to remove BVOPs in a L0 for Simple Scalable: first investigate whether
    1) it really helps and
    2) 2) there is no alternative profile that suits the requirements (e.g. FGS). If 1) removing B-
       VOP‟s helps indeed and 2) there is no alternative solution, then the request will be
       reconsidered.
Proponents where happy with the outcome and will study further, perhaps bringing new proposals t
a next meeting.

m6467          The National Body of JP - JNB Comment on ISO/IEC 14496-2/FPDAM 4
The inclusion of ¼ pel and GMC in Advanced Simple was already decided, if the implementation
conditions were met. The Requirements Group does indeed want to keep compatibility with Simple
@ L0. Also, the group wants to keep B-VOP and MPEG-2 dequant in the lower levels.
Will bit streams for Simple @ L1 be decodable by Advanced Simple @ L0? The Requirements
group does not feel it is required for lower levels of hierarchically higher Profiles to be able to
decode higher levels of lower profiles.
Add Simple Object type to Advanced Simple Profile
Concern about AS L1 not being able to decode S L3  we will make level
The discussion further highlighted that:
   1) In principle, tools stay the same across all levels
   2) If people don‟t want these tools, they should use the Simple Profile.

m6411          A. G. Tescher for USNB - USNB Contribution: Advanced Simple Profile
        Issues
The Requirements group beliefs that all US concerns have been addressed, some of them during this
meeting‟s discussions, some of them already in the past.
As for ISG perform a complexity study on each one of the two proposed tools relative to the tools in
the Advanced Simple Profile:  M3576 gives a study for the complexity of GMC. For Quarter pel
Motion Compensation, the ISG has made studies and contributions in the Fribourg and Stockholm
meetings. As a result of the studies during the Stockholm meeting, a different approach was
pursued, which was presented in the Fribourg meeting. The results of this study can be found in
M3146.

As for The proposers show the coding efficiency gain of each one of the two proposed tools in the
context of the Advanced Simple Profile.  Proof of performance of these tools can be found in
M3146, m3699, m2625 for Quarter pel, m3576, 4085 for GMC. The subjective tests with the
Advanced Coding Efficiency Profile give additional evidence.

As for ¼ pel MC and GMC are considered as two separate tools, not grouped together.  the
contributions referenced above deal with ¼ pel and GMC separately.

m6605           French National Body - French NB comment on Advanced Simple video
        profile
The Group thanked the French NB for the support, and requested it to repeat this in the ballot vote.
As for the request to change the name to Rectangular Advanced Coding Efficiency, the
requirements Group Pro believed that while it may reflect the functionality better, it would be
confusing as it woud be the second name change. Also, people are already communicating about the



                                                 27
profile using the current name. Lastly, „Simple‟ means „Rectangular‟ in an MPEG-4 context. It was
decided not to change the name.

m6609           Weiping Li, et.al. - Comments on ISO/IEC 14496-2 FPDAM4
New techniques (MC in the enhancement layer) could give better performance in some application
spaces. Claims go up to 1.5 db improvement. Including this technology now is impossible,
including it later would mean there would be even more profiles, as we do not want to wait with the
existing ones. The Requirements Group decided to wait and see what will happen. New Profiles can
be proposed using the existing procedures.

Discussions in the Level proposals revealed that the Requirements Group does not want the Level
definitions to be too different across the Profiles. To some extent this is already the case, but an
extra Level was added to the Advanced Simple to bring more balance. Also, the Levels of the
enhancement layers now include a – from the receiving terminal point of view – more realistic
maximum bitrate.

Systems Profiles
m6459          SC 29 Secretariat - Summary of Voting on ISO/IEC 14496-1/FPDAM 2

The 3D Audio Graphics Profile was accepted into Systems V.3. Sphere, Cylinder, Box and Cone
nodes were deleted from that Profile, as the Profile is Audio-only. The 3D Audio Scene Graph
Profile was also accepted into Systems V.3. For both Profiles, it was considered that the
requirements had been met, notably that there was enough industrial support and that there were
conformance commitments.

m6656          Web3D Consortium via SC 29 Secretariat - liaison Statement from Web3D
        Consortium to WG 11 on Proposal for Core Scene Graph Profile
The Requirements Group was happy with this submission, which does not just have a well thought-
through Profile definition but also Level information, something that is missing from some of the
other Systems Profiles.
The proposal went to the Profiles Under Consideration document (N3748), the 'official' document
in which we collect potential new Profiles. It was split into a Scene Graph and a Graphics Profile,
and Level information was separated from the Profile information. Both Profiles are called 'Web3D
Core' at the moment.

The procedure is now that support should be gathered from industry, conformance commitments are
needed and missing details should be worked out. The exact timing and the appropriate amendment
was not yet determined, but it could go in V.4 if the necessary requirements are fulfilled (mature
spec, NB support, company support, conformance commitments). There was a discussion on
whether or not to exclude MovieTexture. The idea was that the visual capabilities, that need to be
supported when this node is present, might be too heavy. The conclusion was that limiting visual
complexity should be done through combining the Profile with Visual Profiles, and that thus the
node in itself incurs no complexity, so that it could remain.

m6603           L. Herrmann, et.al. - Proposal for new 2D Profiles in MPEG-4 Systems
First, the proposal for a Basic AV (Scene Graph and Graphics) Profile – even simpler than simple.
In principle, the proposal was considered a good idea, but the Requirements Group thinks that we
should not limit visual capabilities in the Scene Graph Profile. This means only one level is needed
in the current proposal.




                                                  28
The proposal gives a good overview of Core 2D Scene Graph and Core 2D Graphics and their
relation to the other profiles.

The contribution was merged into the Profiles under Consideration Document. Other companies
should express their support, and give feedback on the exact definitions.

Profiling SNHC tools
m6564           Mahnjin et.al. - Addition of 3DMC to Version 3 Complete Graphics Profile
m6510           Petajan, Han - Inclusion of 3DMC and FBA compression tools in Graphics
        Profiles
It looks logical to use Graphics Profiles to Profile AFX tools. It also seems a good idea to then
include all these tools in the Systems part of the Standard, both the nodes and their compression
tools.
W.r.t. the tools for compression of face and body animation parameters, and indexed face set: it
should be possible to invoke them without the need to implement a Visual Profile, if the
corresponding nodes are in the Graphics Profile.

The philosophy is thus that from now on, the visual SNHC objects should be limited in complexity
through Graphics Profiles, and not visual Profiles. There is still an open question if it is useful to
use Visual Profiles for „stand-alone‟ objects, i.e. objects that can be created without use of Systems.
Pro: they can be created stand-alone. Con: it means that these objects will reside in two types of
Profiles (Graphics and Visual), which is confusing and perhaps detrimental to interoperability.
IPMP
Responses to the CfP were received and evaluated in the Systems Group. Three joint meetings took
place, in which the Requirements Group was informed about the progress. There was consensus to
proceed with an amendment. There is still much discussion on the exact content of this amendment.
Concerns with respect to the implications of something being normative were clarified. It is clear
that ISO will never enforce its standards. MPEG standards are there to conform to if you choose to
do so.
MPEG-4 Overview
The MPEG-4 Overview was updated with minor changes and some additions.

MPEG-7 Promotion to Industry

        AHG
m6602          J. Martinez - Introduction to MPEG-7: Content, Objectives and Technical
        Roadmap
The Awareness Event was briefly discussed in its last details.
A new High Level Overview was approved, but needed to be further edited by Jose Martinez &
Neil Day.
The Detailed Overview lacked Contributions from the groups
It was considered very helpful to write Application/User oriented documents explaining MPEG-7
from a particular use perspective (for example: TV-Anytime and Mobile applications). To write
these, help would be sought from the respective user communities.



                                                  29
MPEG-7 Architecture and Profiling
m6432           Y. Shibata - Study of MPEG-7 Root Elements
m6471           T. Kunieda, et.al. - A Study of the inter-operability issues in standardization
        process
There was again a good discussion on the difficult topic of Profiling in MPEG-7. Much depends on
what is normative behavior, and this links to the question of how to do conformance. Conformance
is easy to define for DS‟s, Schema and Descriptions, but not for decoders. For example, is an
extension of an MPEG-7 Schema Conformant/compliant? Or only partly?
To find answers to these questions, a new document was created, the MPEG-7 Conformance
Definition and Profiles Document, and an AHG was set-up to develop this document.
The document should, when it is fully developed, answer questions like:
 What is normative behavior and conformance for Descriptions
 What is normative behavior and conformance for Decoders
 What is normative behavior and conformance for Schema‟s (Do we need this?? Or is this part of
    Descriptions?)
 How do we creat subsets if the MPEG standard, and do we use Profiles? Do we use the Level
    concept?
 Do we need / can we have multiple dimensions in Profiling?
 What if I want to extend the DSs that exist?

The question was raised whether MPEG-7 allows application-specific extensions; this is
conceivable, if defined by DDL within complexity bounds, and it is possible to specify such
complexity bounds.

Mobile Applications in MPEG-7: specific Requirements
m6442          Mikio Sasaki, et. al. - Report of the MPEG-7 Mobile Applications AHG

It was decided to have a separate document for the mobile applications area, in which MPEG-7
issues are explained and discussed from the mobile application‟s point of view. The AHG would
continue, with the mandate updated to specifically look at profiling from the point of view of the
mobile terminal.

m6440     Mikio Sasaki, H. Nanba, K. Matsugatani - Adaptive Communication using
     Metadata
m6441     Mikio Sasaki, Fumihiko Murase - A Proposal for Retrieval Experiments using
     Dependency Information

After discussion, and clarification by proponents, it was decided to investigate the usefulness of
standardizing a Dependency DS, and to see is standardization is useful, or if tools already exist that
can achieve this functionality. This can be done in a CE.

m6639          F. Duclos, et.al. – MPEG-7 Mobile Applications: New Scenarios
This document proposed to extend the information in Person DS, because Person DS would not be
complete enough to describe a user. It was explained that the person DS was not meant for users,
and that we have had very specific discussions in the past about describing users, even with a
request for NB comments. It was then decided to only standardize user preferences pertaining to
AV content, and nothing more, because of privacy reasons. (See resolution 3.1.12 of the Seoul
meeting, and the Seoul and Vancouver meeting reports).




                                                  30
To the proposal to define an “Organization DS”, the same answer applies as for Peron DS,
following the principles of the earlier discussion

Should terminal capabilities be standardized in MPEG-7? The first answer to this is that it should
not be a part of MPEG-7, but may be worked on by other bodies, but that we should investigate if
our content description matches such externally developed specs. (E.g. in W3C)

MPEG-21
Summary
MPEG-21 Multimedia Framework – Considerable progress in the development of MPEG-21 was
achieved at this meeting. Specifically the following documents were produced:
    A revised and improved version of the Proposed Draft Technical Report (PDTR) called a
       „Study‟ (n3755)
    A Call for Proposals for Digital Item Declaration (n3756)
    A Call for Proposals for Digital Item Identification and Description (n3757)

The following new work items related to MPEG-21 were initiated:
    An „ad-hoc‟ group to focus attention on MPEG-21 outreach to other multimedia initiatives
       and standards bodies (n3765)
    An „ad-hoc‟ group to initiate a Digital Media Standards Summit which could be held in New
       York in April 2001 (see n3764)
    An „ad-hoc‟ group to examine User privacy issues within the context of a multimedia
       framework (n3766)

Two further „ad-hoc‟ groups were established to continue existing streams of work:
   Evaluation of the responses to the CfP for Digital Item Declaration (n3763)
   Further development of the PDTR Study (n3767)

MPEG-21 Multimedia Framework
Following the public publication for comment of the Provisional Draft Technical Report (PDTR) on
the multimedia framework at the last meeting in Beijing a considerable amount of interest has been
developing in this latest MPEG initiative. Many presentations have been given to various industry
forums about the multimedia framework since July. National standards bodies have also been issued
with the PDTR for ballot in December to approve its status.
During the La Baule meeting, work continued to refine the requirements expressed in the PDTR,
and to develop various parts of the report which were felt to be weak. This will be formally
published as a Study on the PDTR after an editing period of two weeks following the end of the La
Baule meeting. It will be released as a public document for comment and continue to be reviewed
and developed at subsequent meetings until it reaches the status of an ISO approved Technical
Report.
It was decided not to create a separate Requirements Document for MPEG-21, as the Technical
Report should also cover these requirements. When the TR is final, a Requirements Document may
again become necessary. (See resolution 3.1.9)

MPEG-21 Calls for Proposals
MPEG-21 prepared and published two Calls for Proposals during the La Baule meeting, based upon
two of the architectural elements which have been defined within the multimedia framework.
The first is Digital Item Declaration. This element describes how the digital item (a structured
digital object with a standard representation and description within the framework, which is also the
fundamental unit of transaction and distribution) can be organised based on a logical structure or
„package‟. Specifically it will specify how many different content types can be assembled into a


                                                 31
true multimedia container so that it can be managed in a predictable way by rendering applications,
networks, terminals, IPMP systems, etc. The Call is expected to attract different categories of
proponents to respond, including those commercial organisations that have developed entirely
proprietary solutions to other multimedia initiatives led by standards bodies. A copy of the CfP is
available (n3756) giving the full timetable for proponents to submit responses. The deadline for
submission is 5th January 2001 and responses will be assessed prior to the next MPEG meeting
scheduled for 15th – 19th January 2001.
The second Call addresses Digital Item Identification and Description and invites the submission of
technology relevant to the multimedia framework. It will specifically invite proponents to submit
solutions for enabling the identification of transactions related to digital items including those
required for the automated management of rights. The requirements for identification and
description associated with the Call have deliberately described in a loose way to encourage a wide
range of submissions. However, certain things have been deliberately excluded from the scope of
the Call including:
    1. Creation identifiers – these are generally well provided for already under the auspices of
        ISO TC46 SC9 and any overlap with their work should be avoided
    2. Watermarking technologies – while the persistent association of an identifier with Digital
        Items will be a requirement of a multimedia framework this Call does not address the
        security and protection of identifiers. This will be the subject of a future Call within the
        context of Intellectual Property Management and Protection.
The Call is expected to attract a range of proponents with a commercial interest in the
implementation of identification systems to support the trade of digital items. This is almost
certainly going to encompass organisations that are responsible for managing rights transactions and
which, for the purpose of automation, they will be required to uniquely identify.
A copy of the CfP (n3757) gives the full timetable for proponents to submit responses. The deadline
for submission will be set following the January 2001 meeting up until 26th February 2001 and
responses will be assessed prior to the subsequent MPEG meeting scheduled for 5th – 9th March
2001 in Singapore.

MPEG-21 Outreach and Summit
The task of defining the multimedia framework within the context of MPEG-21 has always
accepted that the contribution of other multimedia initiatives would be required in order to achieve
integration and cohesion between the architectural elements that require standardisation. MPEG
cannot achieve the task alone and for this reason an „ad-hoc‟ group activity has been created with
the goal of working with other organisations.
As a second „ad-hoc‟ activity, some participants in MPEG-21 believe it would be useful to help
coordinate a digital multimedia standards summit. Some organisations who are understood to be
interested in participating in such an event include WIPO, ISO, IEC and ITU. A time and location
for holding such a summit meeting has provisionally been proposed for April 2001 in New York
City.

Most of the discussions in the break-out were on testing. The Requirements Group was kept
informed on the testing plans.
Watermarking
  m6464      Jean Stride for UK National Committee - UK National Body position on
Watermarking
m6412          A. G. Tescher for USNB - USNB Contribution: Watermarking
An NB comment from the UK asked not to standardize watermarking now, but to develop
requirements first. After a lively discussion, it was decided to give the subject one more chance.
Some good proposals were made to warrant standardization of generic watermarking technology in
MPEG, but the combined case that these proposals make is not yet convincing enough to the
Requirements Group. More of such proposals are needed. It was decided not to continue the
discussions in an Ad Hoc Group (this has been tried unsuccessfully), but to create the
“Applications and Requirements for Standardized Watermarking Technology” document will be
created and to rely on proponents of watermarking standardization to make contributions and make
that document more solid.

fixed accordingly.
Other items may deal with amendment of the MP4 standard :
     Clarify the text about the user-data atom count (at most one);
     Standardize the RTP hint track format;
     Handle of the bit-length problem in audio;
     Add the 'file-type' atom from MJ2;
     Clarify 'optimized for server' hint tracks and the presence of media tracks;
     Support for MPEG-7;
     Add fragmented movie support.

Transport of MPEG-4 over IP Networks
The following contributions have been reviewed :

               6557   Video mapping to system clarification
               6601   Comments on M6447, M6448, M6449 (MPEG-4 over IP)
               6614   FlexMux streams: an RTP payload
               6611   FlexMux signaling
               6612   A FlexMux tool with lower overhead

The framework document has been improved to clearly specify the conformance point to MPE-4
terminal. It has been agreed to use MPEG-4 SL a logical conformance point. This means that the
payload format providing a logical mapping to MPEG-4 SL packet will be compliant to MPEG-4
terminal. Therefore, all the payload format RFCs should have a section describing a logical
mapping from RTP packets to MPEG-4 SL packets explicitly to be considered in the context of this
framework.

Generic payload format Internet-Draft has been revised to allow carriage of multiple SL packets in
one RTP payload. Major technical issues discussed during the meeting are as follows:

     Interleaving shall not be mentioned. If there is a contribution that can draw a consensus
      after this meeting, I-D shall be improved and submitted to IETF by authors (Philippe?). The
      revised I-D will be an input to the next MPEG meeting.
     There shall be no mapping between sequenceNumber in SL packet header and RTP header.
      sequenceNumber in SL packet header will be preserved, if present. But it is recommended
      to use similar features provided by RTP such as timestamp and sequence number.
     If SL packet doesn‟t carry time stamp, appropriate value of RTP time stamp must be
      calculated. But it is strongly recommended to use time stamp in any SL header if it is
      carried by RTP. (This issue is not resolved. Open issue)
     If interleaving is defined, it should be based on packetSequenceNumber, not
      AUsequenceNumber.
     Need to decide on RTP timestamps semantics, delivery time stamp or CTS?
     Use CTS offset for subsequent SL packets within one RTP payload? DTS as well? Yes. (for
      both CTS and DTS).
     Timestamp flag in the first SL packets within RTP packet shall be removed? But it causes
      confusion for the case there is no CTS or DTS originally. ==> No. But revision of SL will
      allow this.


                                                   36
MIME type for MP4 file has been done. “video” shall be used for the top level MIME type. “audio”
can be used optionally for the case of the content with audio without visual presentation.

M6388, M6389, and M6390 were reviewed during the Paris AHG meeting. The decision from the
AHG meeting was to propose an AMD to MPEG-4 system on time stamp flag in SL packet header
as proposed in m6388. m6389 also proposed to have flags in SL packets to indicate concatenation
of AUs in one SL packet but it is not taken as a proposal to an AMD to MPEG-4 system at this
meeting because generic payload format has been improved to carry multiple SL packets in one
RTP packet. m6390 is describing the way of making simple mapping to a subset of generic payload
format.
M6392 was reviewed at the Paris AHG meeting. It was made as an response to the concerns from
IETF people on the was accepted as a reference text on the security section for the all RTP payload
format proposals.
M6612 To propose new syntax of FlexMux having longer length field to carry SL packet larger than
255 bytes. But carrying large SL packet in one FlexMux packet is not aligned with the design goal
of FlexMux. Furthermore, the examples in the contribution are not really valid because MPEG-2
PES packet can carry multiple FlexMux packets.
M6611 To propose in-band signaling mechanism for FlexMux MuxCodeTable by carrying
SMTEntryDescriptor and MuxCodeTable in FCR channel (index=238). Current specification
doesn‟t have in-band signaling mechanism. Out-band signaling method such as DMIF signaling or
SDP shall be used to change FlexMux configuration. For the 4onIP case, signaling MuxCodeTable
is done by SDP but it cannot be exactly synchronized with RTP stream. But changing the USge of
FlexMux to solve the problem from only 4onIP scenario is not favorable because FlexMux is also a
part of MPEG-2 system (4on2). Therefore, we should find out in-band signaling mechanism for
4onIP scenario minimizing the implication to FlexMux specification. This issue will remain open
and be a part of the mandate of 4onIP AHG.
M6614 Proposal of payload format for FlexMux stream is reviewed. Authors‟ will registered it as
an Internet Draft, but it still need improvement.
M6555 Proposal for audio frame concatenation was discussed jointly with Audio. The conclusion
was to improve Civanlar‟s proposal to carry multiple SL packets in one RTP packet.
M6557 Proposal for clarifying the definition of video AU for the case of VOL header. It was agreed
to put VOL header together with the next I-VOP in one AU.
M6584 Requirement for 4onIP was finalized at the Paris AHG meeting and there is no change at
this meeting.
M6601 : This contribution was reviewed while addressing the documents it refers to.

The disposition on these contributions are documented in document N3727 but for the ones below.
M6595: Discussions topics on interoperability, security and standardization.
N3727 describes the answers received to the call, the time they were received, the way they were
reviewed and the understanding of the topic proposed as understood by the Systems sub-group.
The process during the week was to develop an architecture highlighting the normative interfaces
addressed by all contributions, to document the high level functionality addressed by these
interfaces and to exercise these interfaces in application walkthrough. The following functionality
were identified :
20. Renewability of IPMP plug-ins (Interfaces : A, C) for control plug-ins and other Plug-ins
    => Shall we open it to renewability of other things ? We can design it specifically so that it can not do
    everything
21. Interoperability between IPMP Systems and Applications (Interfaces : A, F-B, E)
22. Interoperability between IPMP Systems and Network Layers (Interface D)
23. IPMP Data filter before the IPMP Systems (Interface A)
This are the points that are worth investigating (from a technical and buisness perspective).
The following decisions were made :




                                                       39
24. APIs (Inputs, outputs and behavior) definition, if they were to be defined, would be defined in IDL. This
    will give the possibility to download OS dependent plug-ins. (Additional information like OS, and
    bytecode format may be needed).
25. APIs, if they were to be defined will be defined in Java as well, and java byte code format will be
    identified as a standardized byte code format. This will give a full interoperable framework, although not
    suitable for some devices.
26. The esthetic of the API will be inspired from the DMIF APIs.

IPMP Profiles : Currently, the Core OD profile uses the IPMP messages and descriptors (the hooks)
as defined in 14496-1:2000. There is a conformance specification 14496-4:2000 for MPEG-4 to this
profile. Concerns were raised about the text of the conformance. Evidence should be brought that
the conformance specification is not complete. More profiles may be defined later. There is no need
to define profile yet.

MPEG-7 DDL

                            N°                    Title
                          6499     MPEG-7 DDL Working Draft 4.1

M6499 : The DDL breakout reviewed the Working Draft 4.1 and adjusted MPEG-7 extensions.
The DDL breakout made changes in order to make the DDL fully compliant with XML Schema.
Any MPEG-7 schema will be validated by any XML Schema. However an MPEG-7 parser will
provide a higher level of checking: Arrays have been extended in order to express new kind of
constraints. It is possible to constrain the number of dimensions while not constraining their size.
Due to the new orientation of the MPEG-7 design (mostly a type centric approach) the DDL
breakout replaced the refEltName extension by the refType. This extension allows to constrain the
type of an element referenced by an IDREF.

Joint meeting with MDS/Audio/Video

       The DDL breakout participated to a joint meeting with the MDS, Audio and Video group.
       During this meeting the groups raised concerns and asks for clarification about specific DDL
       extensions.

       The DDL breakout took into account the desire of other groups to have the mechanism of
       Key/KeyRef. This construct have been added to the DDL. However the DDL recommends
       to use it carefully where ID and IDREF constructs can not provide the desired functionality.
       Indeed, this functionality is costly in terms of processing power for the parsers.

       The DDL breakout recommends to use keys when :
  -   adding an ID attribute is superfluous i.e. it already exists one field or a combination of fields
      that are unique within the referenced descriptor and that,
  -   the global scope of IDs makes them difficult to manage for large descriptions.

       The DDL breakout provided a new construct for matrices definition which allows extended
       functionality while preserving XML Schema compatibility. The new feature allows to
       constrain the number of dimension of a matrix while not constraining their size. However if
       a size is not defined in the schema it should be defined later either within sub types or within
       description with the mpeg7:dim attribute.

       The DDL breakout recently decided to adopt XML Schema wildcards because of its need in
       the last version of other groups. In the meantime, the groups renounces to use it. However
       this feature has proved to be useful in the context of MPEG-7. The DDL AHG recommends
       to keep this feature in the DDL.

       Because MPEG-7 is taking a type centric approach for its design, and because key/keyRefs
       provides an element name reference checking, the DDL AHG replaced the refEltName
       extension by the refType extension and IDREF should be used in conjunction with the
       refType extension which replaces the refEltName much more appropriate to the element
       centric approach.


Key and Keyref clarifications

       During the joint meetings, groups asked for clarification about keys and keyrefs.



                                                  42
      A key is independent of the type of the attributes and elements involved, i.e. something
      declared as of type integer may also serve as a key, unlike ID and IDREF. The equality and
      inequality conditions appealed to in checking these constraints applies to the value of the
      fields selected, so that for example 3.0 and 3 would be conflicting keys if they were both
      decimal, but non-conflicting if they were both strings, or one was a string and one a decimal.
      Basically, the comparison between keyref and key or unique is by value equality not by
      string equality.

      The selector (Xpath expression) is defined relatively to instances of the element being
      declared. This must identify a node set of subelements (i.e. elements or contained within the
      declared element) to which the constraint applies.

      The fields specify XPath expressions relative to each element selected by a selector. This
      must identify a single node (element or attribute, not necessarily within the selected
      element) whose content or value, which must be of a simple type, is used in the constraint. It
      is possible to specify an ordered list of fields, to cater to multi-field keys, keyrefs, and
      uniqueness constraints.

      The value of a key must be unique and not nullable (see next for definition), and the name
      that is associated with the key, pNumKey, makes the key referenceable from elsewhere.

      About nullable element

      In general, the absence of an element does not have any particular meaning: It may indicate
      that the information is unknown, or not applicable, or the element may be absent for some
      other reason. Sometimes it is desirable to represent an unshipped item, unknown
      information, or inapplicable information explicitly with an element, rather than by an absent
      element.

Open issues

      About Xpath in instances – OK to check Xpath syntax using pattern but if needed more
      sophisticated checkings have to be carefully evaluated in a later stage of the MPEG-7
      standard. Forward info about Datatype Xpath in W3C on the DDL mailing lists !

      A first attempt to provide an regular expression for an Xpath expression has been done by
      XML Schema WG. This definition might be improved to better reflect the needs of the MDS
      group:
         <simpleType name="XPathExprApprox">
          <annotation>
             <documentation>An XPath expression</documentation>
             <documentation>A utility type, not for public use</documentation>
             </annotation>
             <restriction base="string">
             <pattern value="(/|//|\.|\.\.|:|::|\||(\c-[.:/|])+)+">
                <annotation>
                     <documentation>A VERY permissive definition,
                                    might not be right</documentation>
                </annotation>
             </pattern>
          </restriction>
         </simpleType>




                                                43
       About timeDuration – The DDL AHG should investigate the timeDuration simpleType and
       the constraint it should refer. The DDL AHG will possibly request comments from the XML
       Schema WG. Additional checkings might be needed if not provided by XML Schema.

MPEG-7 Delivery
The following contributions have been reviewed:

       6400   Proposed Requirements for a Content Identification System
       6396   Proposed revisions to requirements for carriage of metadata in MPEG-2 Systems streams
       6407   ISO/IEC 13818-1:2000 AMD1 (carriage of metadata and descriptions over MPEG-2 systems)
       6562   Delivery of MPEG-7 description data over MPEG-2 Transport Stream
       6450   Proposed draft for Carriage of Metadata over MPEG-2
       6565   Delivery of MPEG-7 description data in MPEG-4 Systems over MPEG-2 Transport Stream
       6634   SMPTE Carriage of KLV Metadata over MPEG-2 Systems V6

The requirements for the carriage of metadata in MPEG-2 Systems streams have been updated and
the technical contributions have been studied. Despite the valuable inputs, there was not yet enough
technical consensus to produce text for an amendment to MPEG-2 or MPEG-4 Systems. This will
be postponed to the Pisa meeting.

All these contributions were discussed during the AHG meeting the Sunday before the meeting and
the AHG made recommendations for promotion to the XM and WD.

Basic elements:

m6424 Report of CE on Structured Index DS
      Audrey Tam, Gulisong Nasierding, Clement Leung,
      During the presentation of the CE results, the group felt that the Structured Index had many similarities with
      the Structured Annotation (6Ws). The recommendation was to merge the Structured Index DS with the
      Structured Annotation DSs. This was done during the week and reviewed by the group on Thursday. The new
      Structured Annotation DS (including the features from the Structured Index DS) was recommended to be
      promoted to XM. XM software plan has been developed with the objective that upon completion of the
      software development, the DS could replace the current Structure Annotation DS in the Study of the CD at the
      next meeting.

m6495 Report of CE on Multilevel Indexing Pyramid
      Ana B. Benitez, Alejandro Jaimes, Corinne Jvrgensen, Shih-Fu Chang
      The Multilevel Indexing Pyramid is a tool allowing the classification of visual and audio attributes referring to
      visual and audio content into ten levels: four syntactic levels – type/technique, global distribution, local
      structure, and global composition- and six semantic levels – generic object, generic scene, specific object,
      specific scene, abstract object, and abstract scene. Although the interest of this tool was demonstrated in the
      CE, the discussion revealed that potential overlap exists between this tool and several tools already available in
      the Working Draft (StructuredAnnotation DS, Semantic DS and some Met/Med DSs). The group
      recommended that further studies be carried out to clearly identify whether the Multilevel Indexing Pyramid
      provides new functionalities with regard to existing tools and to define how the Multilevel Indexing Pyramid
      could be integrated in the WD minimizing the overlap with other tools.

m6606 CE on Linguistic DS (Language DS)
      Koiti Hasida, Masahiro Shibata
      The goal of this DS is to describe the semantic of Linguistic data such as written text, speech, etc. The CE
      studied the necessity of the functionality of this DS to describe written documents such as scripts, proposed a
      set of tools and illustrated possible applications. The CE results were discussed during the week and reviewed
      on Thursday. No objection were raised on the final syntax and semantics and the DS was included in the XM.


Content Management:

m6514 Report of CE on EPG DS
      Peter van Beek (on behalf of CE participants)
      The CE report gave some motivations and background information for the Electronic Program Guide DS. The
      CE mainly focussed on the design of the basic building blocks describing the content. It did not propose tools
      to describe the channels nor the high level structure of the EPG. These tools are currently under development
      in the TV AnyTime forum and MPEG will consider and study the TVA proposal once it will be available
      (probably before the next MPEG meeting). The CE resulted in minor extensions of several DSs in the content
      management and the user preferences sections.


Content Description:

m6462 Report of CE on Video Editing DS
      Rosa Ruiloba, Michel Rynderman, Philippe Joly, Yousri Abdeljaoued
      The Video Editing DS is composed of two main parts. The analytical part describes the video editing work of
      already edited sequences whereas the synthetic part describes how to create new sequences from rushes. The
      CE was finalized for the analytical part but not the synthetic part. The proponents were asked to extract the



                                                          46
        DSs addressing the analytical part during the week for inclusion in the XM. This specification was reviewed
        and approved on Thursday. The Synthetic part of the DS will continue under CE.

m6498 Report of CE on Semantic DS
      Ana Benitez, Hawley Rising, Alessandro Bugatti, Corinne Joergensen, Riccardo Leonardi, Koiti Hasida
      The CE results were presented and discussed. The group identified some tools that can be considered as stable
      (already included in the XM and software was contributed). These tools include Semantic DS, SemanticBase
      DS, Object DS, Event DS, Semantic Place DS, and Semantic relations. They will be included in the CD. The
      remaining tools (Concept DS, Semantic State DS, USge Label DS, and the graphical relations) are introduced
      in the XM but will also continue under CE.

m6588 Report on Ordering Key DS CE
      Riccardo Leonardi, Alessandro Bugatti, Yoshiaki Shibata
      This CE proposed some updates in the Syntax and Semantics of the Ordering Key DS. These updates were
      accepted in the XM. However, the tools will continue in the CE to clarify some aspects with regards to the DS
      syntax (in particular, its use of some XPath features).


User interaction:

m6494 Report on the Core Experiment on USge History DS
      A. Mufit Ferman (on behalf of CE participants)
      The CE report reviewed the motivations of this work (requirements document) and gave an overview of past
      activities. Then, the CE proposed a new specification of the USge History which combines most of the
      advantages of past proposals. The group accepted this proposal for inclusion in the XM. Future work will
      include software implementation, and also the definition of classification scheme for action (list of possible
      USge).


Description Schemes Promoted to XM and CD
The following table summarizes the group decision with regard to promotion to XM and CD (note
that some promotions to CD result from XM Software integration between the Beijing and the La
Baule meeting).

m6530 Proposed Modifications for the Description of People and Places
      Corinne Joergensen, Deborah Karpuk, Toby Walker
      This contribution provided some information on standard practices used to specify Persons (Agent) and Places
      in the field of library and information science. It was agreed to expand the relevant informative sections of the
      MDS documents to include standard cataloguing elements, to add informative guidelines on how to instantiate
      the DSs, and to provide references to existing library cataloguing practice.

m6531 Proposed Revisions to the Graph DS
      Toby Walker
      This proposal presented several minor extensions to the Graph DS in response to the issues raised by USNB
      review of the MDS documents. The main issues were: 1) constrain the type of nodes and relations in a graph,
      2) the use of the Relation Property DS and 3) Check of the consistency of the relations in a graph. After
      discussion, the group agreed to merge the RelationLink DS and the Edge DS into a single Relation. The
      proposed constraining mechanism uses RefEltName. The status of this "RefEltName" feature in the DDL
      specification was not known during the discussion and should be checked.

m6646 Graph Rewriting Rules and their Application to Restrictions of Relations and Semantic DS
      Hawley K. Rising III
      This contribution highlighted the power of graph structures (Graph DS) for creating descriptions, and also for
      combining, editing, updating, and restricting descriptions based on graphs. In the contribution, several graph
      rewriting rules and examples were discussed. The use of graphs and graph rewriting to restrict the vocabularies
      of entities and their relations in writing descriptions was also illustrated. The group recommended that a CE be
      started at the end of the week (see N3632).

m6533 Proposed Improvements for Controlled Terms and Classification Schemes
      Toby Walker
      The functionality of the Classification Schemes (CS) is to control the vocabulary of the description. The
      proposal reviewed the current specification of the CS and proposed solutions to improve the specification. The
      main modifications involve new features to the CS to support multimedia thesauri, a richer set of term
      relations, definition of relations in (CS), and a placeholder for formal representations of the meaning of terms.
      These proposals were accepted by the group. Also, the issue of standardizing the thesauri was analyzed. After
      discussion within the MDS group and also at the MPEG chair meeting, it is recommended to define (when
      possible) a set of normative enumerated lists or of default thesauri. Their use, however, should not be
      normative, and each application should be able to use a different set of dictionaries. The use of registration
      authority for non-normative dictionaries should be further investigated.

m6532 Proposal for a MetaMeta DS
      Toby Walker
      This proposal highlighted the necessity to have information about the metadata (who has created the
      description, when, for which purpose, etc). During the discussion, it became apparent that this proposal had
      some overlap with activities related to the definition of the root elements. It was felt that some further
      investigation and harmonization were needed. A CE on this subject was approved at the end of the week (see
      N3634).

m6432 Study of MPEG-7 Root Elements
      Y. Shibata
      This proposal suggested a set of new attributes to be included in the root elements and some improvements on
      the root elements syntax. Some of the proposed attributes addressed Systems issues and it was decided not to
      include this type of information in the root elements but to include them in the Access Unit DS defined in the
      Systems CD. During the discussion, the lack of understanding of conformance in the MPEG-7 framework
      became apparent. A new AHG dealing with conformance and profiles was approved by the Requirements
      group at the end of the week (N3762).

m6492 Proposal for Additional MDS Media Format and Coding Elements for Internet Streaming Media
      Eric Rehm
      Most of the modifications suggested by these contributions were already discussed during the AHG on editing
      the MDS XM & WD and were already taken into account for version 4.1 of the MDS XM & WD. The
      proposed list of normative dictionaries were reviewed and were approved. As mentioned before, MPEG will
      specify a set of normative dictionaries but their USge will not be mandatory and each application will have the
      opportunity to use non-normative dictionaries.

m6591 Additional Attributes to Support Transcoding and Comments
      Anthony Vetro
      This contribution proposed the addition of two new features (transparent blocks, quantization). Also the
      interest of the IntraFrameDistance and AnchorFrameDistance description was discussed. Finally, the proposal
      also suggested to merge the MediaCoding and the MediaFormat entities. All these suggestions were approved
      by the group.

m6493 Proposal for electronic ink document
      Z-Y Shae, J. Subrahmonia, J. Pitrelli, L. Schomaker, et al.
      This contribution discussed the interest of electronic ink documents and the necessity to describe them. Major
      applications include distance education, conferencing, pen systems and electronic whiteboards. The goal of the
      proposed set of DSs is not only to describe what is written or drawn but also the gesture. Is was suggest to
      define a new Segment called "InkSegment". InkSegment is a subclass of Moving Region. In the same proposal,
      several extensions of MediaLocators were also defined. At the end of the week, a new CE in the area of
      InkDocument was approved (N3633).

m6497 Segment Relations for MPEG-7
      Ana B. Benitez, Shih-Fu Chang
      This contribution proposed a set of Segment relations. The relations are the classical spatial/temporal and
      topological relations. This proposal was also reviewed by the video group. Two sets of definition were
      proposed for topological relations. It was decided to use the definition based on set operations.

m6508 Identifying HighlightLevel in Summary DS
      Sanghoon Sull, Hyeokman Kim
      This contribution proposed to add an ID attribute to HighlightLevel in Summary DS. This attribute is necessary
      in order to be able to refer to a subtree of a hierarchical summary tree. The group agrees to make this minor
      change.

m6425 Shape-Sequence Descriptors for a spatio-temporal regions,
       Gyu-Tae Baek, Sang-Youn Lee, Young-Sik Choi and Sang-Hong Lee, Hae-Kwang Kim, Seoung-Jun, Oh.
       This proposal involved defining a type of Dynamic Visual Object Image and was previously presented to the
       Video group. The proposed descriptor summarizes the changing 2-D shape of object over time. The summary
       is represented by a single 2-D image. The MDS group pointed out several places where this functionality
       seems to be currently supported, including using the object summary image as a key-frame in a video
       summary, or allowing the image to be a “keyFor” a moving region. Since the proposal does not provide any
       parameterized representation of the moving object, it does not seem possible to apply matching methods to or
       other types of automatic processing of the Visual Object image. It is also not apparent how the proposed tool
       would be appropriate for Video group. The recommendation was given for the presenter to (1) gain a better
       understanding of the relevant sections of the MDS specification (Segment, Summary), (2) discuss with
       appropriate MDS members who have knowledge of the relevant sections, and (3) consider alternative
       implementations using existing tools.



Review of individual section of the MDS XM / WD
During the week, all sections of the XM and WD were reviewed by the group. This review took into
consideration the comments included in the report of the AHG on MDS XM & WD editing (Input
document M6478). During the week, it was agreed with the audio and the video groups to specify
the TemporalInterpolation tool in the Video CD and the ScalableSeries Tool in the Audio CD.

m6479 Metadata Integration: Dictionary, current status, and open issues
      E. Oltmans, J.P. Evain, J.M. Martinez, P. Mulder
      This contribution made a review of the current status of the dictionary. The dictionary is useful to allow
      comparison with other metadata standard but also to detect inconsistencies in the definition of DSs or Ds. The
      major issue concerning the dictionary definition is the duplication of terms. As MPEG has chosen to strongly
      structure the description, the semantic of a DS or D may depend on its context. As a result, entities with the
      same name can have different meaning depending on the context they are used. The work was continued in a
      Breakout Group. It was concluded that, depending on the DS or D, one of the following solutions could be
      used: 1) compressed the entries in the dictionary when the elements and their semantics are exactly the same,
      2) rename the entry if the semantic significantly differs. In terms of editing the CD, this work will useful to
      improve the semantics of some tools and maybe to rename some entities.

m6500 Proposal for the Integration of Dublin Core and MPEG-7
      Jane Hunter(Analyzed and Presented by Eric Rehm)
      This proposal discussed how schemes coming from two different metadata standards (syntax based on the
      XML Schema) could be combined. The proposed solution was based on name space. An alternative solution
      was also discussed by Eric Rehm. It relied on the use of XSL to transform the schema of one metadata standard
      to the schema of another standard. Another solution that may be further investigated is the use of Packages.
      During the discussion, it was pointed out that this kind of information should be collected into a document that
      could help people having to combine MPEG-7 with other metadata standard.

m6543 Proposal: MPEG-7 SequentialSummaryDS meets TVAnytime
      D. Ponceleon, O. Hori, M. Sugano, T. McGee, et al.
      This contribution was mainly informative: its goal was to inform the MDS group about an initiative of a certain

m6547 Status of Software integration for DS
      Stephan Herrmann
      The review of the document revealed that the software packages of most MDS tools in the XM have been
      delivered to the ISG group. Because of the large amount of software contributed between the Beijing and the
      La Baule meeting, it was not possible to integrate and check all packages. This will be done in the future.

m6540 Documentation for Fast Audio Moving Storyboard XM software
      Dulce Ponceleon, Jan Pieper, Gilad Cohen
m6541 Documentation for Textual Summaries from Speech Transcript
      Dulce Ponceleon, Jan Pieper
      These two contributions were examples of documentation to be provided with the software. After discussion, it
      was agreed to create a template for documentation on the basis of these proposals. The template can be found
      in N3659.


Workplan for software integration
Toby Walker, Ana Benitez
The following workplan for software integration was approved by the ISG and MDS groups:

        Status of DDL, XML Schema
        C. Seyrat
        The chair of the AHG on DDL explained the recent modifications of the XML Schema and the update of the
        DDL (Introduction of Unique, key, keyref, wildcard). Because of the recent update of the XML Schema, all
        schema defined by MPEG-7 will have to be modified. Eric Rehm volunteered to investigate the possibility to
        use XSL for automatic conversion. In terms of MPEG-7 extensions, the current strategy of the DDL group is to
        use the AppInfo construct of the XML Schema. As a result, MPEG-7 specific extension can be parsed by a
        generic XML Schema parser.

m6435 A Base Class Hierarchy for MPEG-7
      P N Garner, A de Cheveigne, Y Shibata
      This contribution proposed a complete hierarchy of type inheritance and body / header structures. This
      proposal was discussed but the activity continued in a breakout group. The final results were reviewed on
      Thursday afternoon and will be included in the Schema Tools section of the MDS CD.

m6433 Guidelines for DDL representation of MPEG-7 DSs and Ds ver.1.1

m6431 Additional DDL Representation Guidelines regarding Global El. Decl.
      Y. Shibata
      The guidelines were reviewed. The issue of Type-centric versus Element-centric design approach was
      discussed. The group decision was to adopt a type centric approach and to define a type inheritance hierarchy.
      The guidelines document was updated accordingly (N3625).

m6581 a DDL-based HTML Documentation generator for DSs and Ds
      Cedric Thienot, Claude Seyrat, Gregoire Pau.
      This contribution discussed the interest of including the documentation and even some examples in the schema
      definition itself. It is then possible to use a software tool to automatically extract the documentation and to
      create a set of HTML files and link the various components in the file. This tool could of great help for
      developers. In terms of the specification of the Schema in the standard, it was decided not to specify
      <annotation> and <documentation> in the normative sections defining the syntax. However, in the future, the
      creation of a documented Schema can be envisaged.


Joint meeting with Systems and Requirements

             m6441 A Proposal for Retrieval Experiments using Dependency Information

During the first part of the meeting, the MPEG-7 System Architecture was discussed. The global
architecture was reviewed and the use of MP4 file format was discussed. A diagram illustrating
some possible conformance points was also proposed. Finally, the notion of access units was
introduced and its relation with roots elements was highlighted. It was decided that root elements
should not include Systems related attribute, but it was also recognized that, at the next meeting,
harmonization needs to be made between access units and root elements. In the second part of the
meeting (only with requirements), the group discussed the meaning of conformance and
interoperability. Is was decided to create an AHG at the end of the week to work on these two issues
(N3762).
m6441 A Proposal for Retrieval Experiments using Dependency Information
      Mikio Sasaki, Fumihiko Murase
      This document proposed an experiment to evaluate the use of Dependency information in mobile applications
      such as location-sensitive video push. The experiment will analyze the use of Dependency Code for Media
      (DCM) binary encoding of metadata to speed-up matching and retrieval. Problems were pointed out that the
      proposed material involves a compilation and encoding of descriptions and should be considered as a systems-
      level. Also the proposed Dependency Information was fixed and too limited. It is not apparent how to extend
      the given information to accommodate many other dimensions of description. Recommendation was made to
      develop the semantics of the Dependency Information DS for the CE, to develop an extensible structure that
      would use additional Ds and DSs, to investigate a wider variety of application needs by enriching the
      description of the context and to analyze whether this kind of information need new tools or can already be
      handled by the current set of MPEG-7 tools.

m6619 Report of the AHG on Conceptual Modeling
      John R. Smith, Uma Srinivasan
      This AHG has produced a complete conceptual model, has tracked and analyzed the principal concepts
      involved and MPEG-7, and has produced a set of guidelines to distinguish between DSs and Ds and also
      between global and local elements. The mandates of the AHG are considered as being very successfully
      completed.

m6511 MPEG-7 Issues Regarding MPEG-4 Synthetic Objects
      Eric Petajan, Zon-Yin Shae, Ajay Divakaran, Tsuhan Chen
      This contribution highlighted the interest of the SNHC work for MPEG-7. It was agreed that there is currently
      a lack of tools in MPEG-7 to describe synthetic objects and that SNHC tools are of great interest in this
      context. On the one hand side, it was decided to work on naming issues in the context of the AHG on Audio,
      Video and MDS harmonization. On the other hand side, the technical work will be pursued in the framework
      of the Video group.

MPEG-4


21 Version 2 Reference Software

Work on software /bitstream verification was discussed. Only marginal bugs were found and further
integration will continue in the context of FGS and Studio profile. Minor bug fixing on the Version
2 software will continue until Pisa meeting. It is expected that after
the Pisa meeting the Version 2 software will reach FDAM status.

Version 1 and 2 Encoder Optimization

The Optimization Model (OM) includes tools which optimize MPEG-4. A number of tools are
currently under consideraton for further optimization, including fast global motion estimation and
fast on-line sprite generation. At the meeting the fast global motion estimation was accepted for
inclusion into the OM. OM version 2.0 was issued. In order to further optimize the quality of
MPEG video, work on R-D optimization was initiated and a Core Experiment was defined.

Version 3 Studio Application

A number of technical details are still under consideration for the definition of the studio profile.
Lossless coding, shape and sprite coding will be supported by this part of the standard. At the
meeting JPese National body comments were discussed and a study of FPDAM was issued. A
DAM is targeted for January 20001. The study of FPDAM includes the following updates,

   Marker bits, max sprite size
   Lossless DPCM coding
   Hierarchical Huffman Coding for Binary shape
   Downloadable VLC Table
   IDCT precision extension
   RGB and 12 bits per sample signal
   Correction of some editorial errors

With respect to subjective Verification Tests and Conformance activities the following schedules
were defined:

Test Schedule:

   Until January 2001:

Fine Granularity Scalability

At the meeting National Body comments were discussed and a study of the FPDAM as well as VM
18.0 of the standard was released. DAM is targeted for January 20001. A possible Version 2 of FGS
was discussed to incorporate further additions and improvements to FGS. Current FGS profile
meets the requirements for streaming video over variable bandwidth channels. However, for high
quality video distribution, FGS is a desired functionality but coding efficiency needs further
improvement. Potential Version 2 technologies include enhancement layer motion compensation.

Also for FGS a Test and Conformance schedules and details were defined. The schedules follow
those of the Studio Profile. For the Verification Tests the following details were approved:

   Test 1 : Comparison FGS/Multicast 3
   Test 2 : Dynamic Channel Conditions:
        -        Network with priority setting
        -        Best effort network
        -        Wireless network
   Test Sequences : As in Core Experiments.
   Result Evaluation based on subjective Assessment
   First draft defined jointly with Test Subgroup


Call for Proposals for Coding Efficiency

Results of a Call for Evidence indicated, that there may be technology available to improve coding
efficiency. As a result MPEG issued a Preliminary Call for Proposals at the Bejing meeting. At the
LaBaule meeting a final Call for Proposals was issued to solicit input to a formal subjective test.
The primary purpose is to test the quality of coded video at low and medium bit rates. MPEG-4
anchor sequences will be generated by HHI and EVue. The schedule foresees anchor sequences to
be available and proposals registered by January Pisa meeting. The Tests will take place at Intel US
premises prior to the March MPEG meeting and results of the tests will be available at the March
meeting.




                                                 60
MPEG-7

At the meeting the following technologies were promoted to WD/C

•    VisualTemporalArray descriptor
•    Optimization of ExtensionFlag in Color Layout descriptor
•    Face Recognition descriptor
•    Spatial 2D Coordinate System descriptor
•    Improvements to Colour structure descriptor
•    Bit-plane coding for scalable histogram
•    3D Shape

Based on decisions in the group the descriptors for Bounding box, Container descriptors group,
VisualTemporalArray, GridLayout, 2D/3D Multiview were removed from the CD.
A number of descriptors were updated for consistency.

Detailed review of the CD and XM documents lead to a good quality CD document. This review
process included personal reviewers for each descriptor and multistage reviewing.
Overlaps between decriptions were detected, e.g. region locator and bounding box.

Task Groups


                                                       62
Six task groups were convened for the duration of the MPEG meeting, as shown in ANNEX-III.
Results of task group activities are reported below.

Record of Audio plenary, joint meetings and task group activities
Audio plenary discussions
Audio plenary discussions consisted of review and approval of work done by the task groups.
Joint meeting discussions
MPEG-4 on IP
The groundwork for this meeting began in the Monday afternoon audio plenary when the Chair
called contribution M6555 “Audio frames concatenation,” to the attention of the group. The author,
Philippe Gentric, was present and presented the contribution. The main point of his contribution
was that current IETF drafts for carrying MPEG-4 audio over IP do not achieve sufficiently low
RTP packetization overhead in the case that the MPEG-4 audio data is from a 2 kb/s speech coder.
In the ensuing discussion the tables shown in Annex A-VI were constructed.
The joint meeting with Systems began with a review of these tables, which made it quite clear that
carrying 2 kb/s coded speech using the Civanlar draft incurred an 800% overhead, while using the
LATM draft required a 100% overhead. Neither is a competitive solution for the application
segment of delay-insensitive streaming of low-rate speech signals. The Systems subgroup repeated
points from the AHG report on MP4 on IP, which were that the recommended requirements for
MP4 on IP were:
     One generic payload format
     Other formats should be a subset of this format
These requirements are also in ietf-avt-rtp-mpeg4-es-xx.txt. After much discussion, both in this joint meeting and later
in Audio plenary, the Audio subgroup endorsed the following principles for making progress on a unified MP4 on IP
IETF draft:
        a new or revised IETF draft that has multiple SL packets per RTP packet, which
             o Reduces packetization overhead, especially for 2 kb/s coded signals
             o Supports error resilient streaming
             o Supports any MPEG-4 Elementary Stream
        •that the SL packet interface can be common to all IETF drafts for MP4onIP.
XM integration
ISG talked about how applications would run on the XM. They envision three types of applications:

Media based
   MPEG-7 database: extracted directly from media via procedures that are typically tightly
      integrated into the XM. The normative metadata resides in an internal C++ representation,
      but can also be written to a file in an XML or BiM representation.
   Query: query is a media segment that represents the query target. As in database generation,
      the normative meta-data is extracted directly from the media and stored into an internal C++
      representation.
   Match: show best match(es) by operating on internal C++ representation of meta-data.


DDL based
   MPEG-7 database: extraction can be outside of XM, via C++ code, other code (e.g. matlab)
     or via interface to widely available 3rd party product (e.g. a speech recogniser). The
     extraction procedure reads media files and writes the XML instantiations that are the
     normative MPEG-7 meta-data. The XML instantiations are read into the XM, populate a


                                                           63
       DOM tree and are loaded into an internal C++ representation for subsequent matching
       operations
      Query: query is an XML instantiation, which is read by the XM, populates a DOM tree and
       is loaded into an internal C++ representation for subsequent matching operations
      Match: show best match(es) by operating on internal C++ representation of meta-data.


Transcoding
    Query: query is an XML instantiation, which is read by the XM, populates a DOM tree and
     is loaded into an internal C++ representation for subsequent matching operations
    Match: media is read into XM and meta-data extraction is done as the media is read. The
     media segments that match the query target are indicated. An example of such an
     application is to extract and display the desired keyframes from video sequences.

The Audio subgroup and ISG agreed that Audio subgroup‟s part in the XM integration of Spoken
Content is complete, as it has provided the necessary code for the XM, and that ISG has to integrate
that code into the XM code base. The Spoken Content CE is an example of a DDL based
application, in which
     An external extraction procedure with interfaces to a 3rd party speech recogniser reads media
        files and writes a file of XML instantiations of the normative meta-data.
     The XM DDL parser reads the XML produced by the extraction procedure and, via DOM
        interface, (actually generic DS interface), fills C++ classes for use by the query process.

The Audio subgroup agreed that most audio Ds and DSs will be DDL applications. As such,
    The extraction phase can be either tightly integrated into the XM or executed by a procedure
      external to the XM, and computed via any of the following
          o C++ code
          o Matlab scripts
          o Documented C++ interfaces to commercial 3rd party applications (e.g. a speech
             recogniser).
    The extraction phase reads media files and writes normative XML instantiations of the appropriate Ds
and DSs, which comprise the MPEG-7 database that can be queried.
      The query is posed as an XML instantiation of the appropriate Ds and DSs.
      In the matching process, the XM reads in the database of XML instantiations and populates
       a DOM tree and then reads in the query target XML instantiations and populates a DOM
       tree. An interface to the DOM tree writes the data to an internal C++ representation.
       Application-specific procedures operate on the C++ representation to present the best
       match(es) to the query target.
      The matching phase will be tightly integrated into the XM.

The schedule for integration into the XM is as follows:
    External extraction procedure:                  All audio CE completed by Jan 10, 2001.
    Tightly integrated matching procedure           All audio CE completed by TBD
Task group discussions
MPEG-4 V2 conformance, 14496-4/Amd 1 (FDAM Jan 01) – contributed by Ralph
Sperschneider

Conformance text
M6487 has been used as starting point.



                                                  64
Comments made in M6558 have been reviewed. More detailed information on scalable reference
waveforms should be added. Some details regarding the test sequence definition for epConfig==2
needs to be revised. The revised description has been included.
Comments made in M6604 have been reviewed. The proposal was withdrawn.
Open issues related to HILN have been reviewed and included.
The test procedure for RMS (“full accuracy” decoders) has been reviewed.

Conformance work plan
M6488 has been used as starting point.
The tables reflecting the test sequences have been updated.
The time schedules have been revised.

Proposed corrections on Audio conformance
N3486 has been used as starting point.
Corrections made in N3485 (ISO/IEC 14496-3:1999/Cor.1:2001) have been reviewed w. r. t. their
impact of Audio conformance, appropriate information stated in N6463 has been used as a starting
point.
Some corrections with respect to a common file name convention have been added.
MPEG-4 Reference Software 14496-5/Amd 1 (FDAM Oct 00)
Thursday from 09:30 to 13:00, interested Audio subgroup members met with Markus Werner of
SEED and reviewed the proposed agenda and scope of work for the MPEG-4 Audio VM
framework re-write. The program of work that was agreed on at that meeting is show in the
ANNEX A of N3646, “Status and Workplan for MPEG-4 Audio Reference Software.” The Chair
is happy to note that three more companies indicated interest in supporting the re-write effort.
The major goals of the framework re-write are that the top-level code will
       Read MP4 file format.
       Route Access Units to a single, unified, interface to the various underlying audio object type
        decoders.
     Write audio files in any of several formats.
The re-write task is expected to be completed by the time of the march MPEG meeting, and so the
corrigendum to replace the existing MPEG-4 audio reference software with the new software could
be started at that meeting.
MPEG-4 Corrigenda and 2nd Edition
At the Beijing MPEG meeting the Audio subgroup began a corrigendum against MPEG-4 version 1
audio. Since there is only one ballot cycle for a corrigendum, and since the ballot for this
corrigendum, 14496-3/1999:DCOR1, closes 2001-01-06, it is important to note the national bodies
are able to issue comments on this ballot item. A poll taken in Audio plenary indicated that the
following national bodies could make ballot comments:

                                   NB       Meeting Date        Contact
                                   JNB      Dec 2000            Takehiro Moriya
                                   KNB      (by email)          Sang-Wook Kim
                                   GNB      (by email)          Jurgen Herre

As part of a related effort, there will be an AhG activity to roll the Audio Version 1 and Version 2
text into a single document that also incorporates the changes indicated in the corrigendum. This
will issue at the same time that 14496-3/1999:DCOR1 issues. Since these changes are only
editorial (the combination of Version 1 and Version 2 text) or have already been approved by ballot



                                                           65
elsewhere (the 14496-3/1999:DCOR1 ballot), the MPEG-4 Audio Edition 2001 can issue without
any balloting.
MPEG-7 Audio 15938-3 (CD Oct 00)
Phil Garner, Canon, was named editor of the MPEG-7 Audio text. Other editors may be named at
future meetings. A small but dedicated group worked on incorporating DDL changes and stylistic
changes into the document. In addition, the melody and the silence description schemes were
promoted into the CD and the scalable series description scheme was moved from MDS back to
Audio. The document will have an editing period to end November 27th.
The timetable for progression of the MPEG-7 Audio standard is as follows:

MPEG-7 Audio core experiments and other business – contributed by Adam Lindsay
Tues: 1000-1300
MDS-Video-Audio-DDL Joint status of XML Schema/DDL
We saw several inputs of general relevance to MPEG-7. One big issue of note is that the DDL is
tracking current changes in XML schema, which is expected to be draft recommendation soon,
therefore more stable. However, there are no guarantees that it won't change again.
Tues: 1330-1500
Reviewing input documents
Vincent presented XM integration problems for Timbre DS. Basic audio functionalities are
unavailable.
Agreement was reached on Silence: best to let minimal parameters to identify application/semantics
of segmentation. Thus only the "major silences," or the silences that are not extremely sensitive to
parameter changes, are reflected by this slightly edited DS.
Tues 15:00-18:30
Joint with ISG re: XM
This was a long, hard process, in which Schuyler finally got them to agree to MATLAB as an
extraction tool for the purpose of XM integration.
Wed 12:20-18:00
Melody input
The MIT Presentation and demo sparked lots of competing suggestions, but the proposal at hand
was the one that received review and technical input. Still, the discussion provoked questions like,
what is the "sweet spot" between terseness and flexibility. We saw a demo (unofficial, as there was
no input document) of a similar query-by-humming application from FR Telecom. It demonstrated
a very different strategy for melodic search using a much larger database. In light of this further
demonstration, and considering the subgroup chair's encouragement to exercise their prerogative as
"experts," the breakout group spent some time reaching a rough consensus on a more complex
Melody DS, building on an informal document from Ron Goodman, Creative.


                                                 66
Thu 09:30 – 18:00
On Thursday morning we heard a brief report on the XM joint meeting: We are to provide, by 10
Jan, applications that output XML descriptions. As a next step, these XML descriptions would be
read into the XM and a matching system executed (this would represent the most complex part of
XM integration).
In a discussion on what's still needed in the standard we heard a few suggestions on providing
facilities for non-normative extensions to the standard. A company considering MPEG-7 may wish
to include a data field for private data or data that has no reason to be standardized (e.g. audio
fingerprints). Not seeing a clear means for extension within the audio part of the standard, they may
pass over the standard. The traditional MPEG-7 response to this is that the standard is highly
extensible, via the DDL, which may aid in partial interoperability via its highly structured data
fields.
It was noted that the MDS document's example of a controlled term list holds a hierarchy "upside
down." This is odd, and we should seek more explanation, as our dictionaries will depend heavily
on this construct.
The subgroup should consider a music industry profile.
The breakout group committed to applications of the DSs to make contributions to the "monster
description" example instantiation.
Perhaps Zero Crossing Rate should be included in the Audio Descriptor Framework.
The remainder of the meeting was dedicated to document editing and review.
Audio Call for Evidence
The task group revised the Audio Call document to add Annex I. This Annex lists the registrants,
indicates what MPEG-4 “reference quality” materials each of them needs, indicates who will supply
these materials and when they will be supplied. In addition it proposes that the materials be made
available via a passworded FTP site hosted at the University of Hanover. Details on the FTP site
will be posted on the Audio Call AhG reflector.

Works & Results
Version 2 – FBA Conformance
All the conformant bit streams are delivered and finalized. The integration of FBA tools to IM-1
is still found not to be complete: a slow decoding problem. The IM-1 implementation will
continue till January with the new work plan (N3716)
Version 2 – 3DMC Conformance
The implementation of 3DMC in Player3D of IM-1 continues till January 2001. Some problems
in implementing 3DMC within BIFS are identified in the contribution of M6563. As an outcome
of the discussion with Systems, both the informative and normative descriptions on the USge of
3DMC have been incorporated into Systems DCOR1 (N3714).
Version X – Graphics profiles with SNHC tools
There were two contributions proposing Graphics profiles with SNHC tools (M6510, M6564).
Several joint meetings with Systems and Requirements groups were held for further discussions
on how to define Graphics profiles. The following items are identified through the discussion:
 For the Graphics-related profiles, the definition of level is very weak. There was an input
    contribution from Web3D Consortium (M6656). Agreement reached to define the levels on
    Graphics profiles based on the Web3D contribution. Yet, further thoughts should be given for
    the finer definition of levels in the future.
 Regarding the requests to design Graphics profiles (possibly) in Version 3 (M6510, M6564),
    a decision is taken not to pursue immediate definition of new profiles. It is to give more
    thoughts on the definition of new profiles as well as to draw more industrial attention before
    designing new profiles.
 In MPEG-4, there are some Graphics tools specified both in Systems and in Visual
    specifications. For stand-alone tools, it has been considered mainly in Visual specification.
    But for the future standard development in MPEG-4, it was identified that it would be better
    to treat in Systems specification where Graphics profiles are designed. And the decision is
    reflected in the Requirements Group resolutions (N3615).
Version 5 – Animation Framework eXtension (AFX)
Discussion on the animation framework continued in the meeting with 5 responses made by
September 15, 2000. The evaluation meeting for the responses to CFP was held on October 22,
2000. Review of the evaluation meeting will be found in M6652.
AFX Requirements: There was in-depth discussion on the AFX requirements during the week.
The final version of the summarized requirements has been reflected to the Requirements
document (N3746).
Test data collection: the SNHC group felt that more test data will be necessary for the on-going
development of the AFX standard. The participating companies agreed to cooperate to collect the
common test materials.

AFX S/W implementation: There were some companies who tried to provide integrated S/W
for the SNHC tools in MPEG-4. This notion is inherited to the development of AFX standards.
We have identified some companies (blaxxun, Mantis Corp., iVast, Samsung, Superscape,
Avipix) who will develop the S/W platform for AFX standard. An AHG was established to
manage the S/W development (N3698).
AFX development plan: It was planned to start with VM (N3699). The AFX standard will be
developed with the following schedule:

Core experiments: The AFX standard will be developed based on the guidelines specified in
N2200. The following core experiments will be designed and performed till January 2001:
A1: Interpolator compression (Samsung)
A2: Subdivision Surfaces (Superscape)
A3: Animation path representation (iVast)
A4: Multitexturing (iVast, Superscape)
The group acknowledged a need of coordination between Web3D and MPEG. As a positive sign
of collaboration between MPEG and Web3D, a joint meeting is planned during the period of
Web3D Conference in 2001.
MPEG-7 SNHC
There was an input contribution about SNHC tools in MPEG-4 that are relevant to MPEG-7
Visual (M6511). A joint meeting with MMDS and Video groups was helpful to understand the
nature of SNHC tools in MPEG-7. In order to have a better look at the issue, further contributions
from the proponents are expected at January. Name scope collision was also identified as another
issue between MPEG-4 and MPEG-7. This problem will be studied in the continuing AHG
activity (N3638).
SNHC E-mail reflectors
There was a short discussion on the e-mail reflector for on-going activities. Some reflectors
seemed to have problems in subscribing new members. Everyone agreed that new e-mail
reflectors can be established whenever needed. For the time being, the current reflectors will be
in use unless they are troublesome to use.
SNHC FAQ update
FAQ of SNHC was reviewed by SNHC members and got fixed with 3 new Q&As. It was decided
not to officially update the FAQ this time due to the marginal changes to the FAQ. Dr. Eric
Petajan is currently in charge of maintaining the FAQ draft

Summary
Objectives for the 54th meeting of WG11, in La Baule, FR, were the definition of content,
methodology, and issuance of two Calls for Proposal; one for new video coding technology for
MPEG-4 and one for Digital Cinema. Initial work was to be done to define verification tests for
MPEG-4 Version 4 (Studio Profile) and MPEG-4 Version 5 (FGS). These objectives were
satsified but the Digital Cinema Call for Proposals (CfP) was postponed to continue definition of
content and test methodology. Test issues related to the MPEG-4 Video CfP were discussed and
the CfP was issued (from Video). Initial work commenced on the FGS and Studio Profile
verification tests.

Contribution Review
Contributions from the USNB concerning evaluation procedures for both DCinema and Video
were considered and answered. Significantly, the decision was made to use short sequences for
sequential evaluation, and longer sequences for side-by-side evaluation.

Detailed Work Items
MPEG-4 Version 2 Video CfP
Facilities volunteered by Intel were accepted for the subjective testing scheduled Feb 26-28,
2001.
Test content was selected to conduct meaningful tests based on anticipated registrations and test
time available. The many levels from the preliminary call-for-proposals were reduced to two:
Low Bitrate (QCIF) and Medium Bitrate (CIF).

The test process was refined and summarized in N3671. The process follows ITU-R BT500-10,
which has been used in previous tests, with some major exceptions. First, due to the progressive
                                                86
content selected for the trials, progressive monitors were selected for viewing. Second, a side-
by-side technique for evaluation is considered in addition to or in replacement to the double-
stimulus sequential technique. This approach may be refined based on additional input from test
experts in the AHG. Third, viewing distances have been modified to include much closer
viewing than traditional techniques. The test hardware configuration is likely to be similar to that
used for informal FGS evaluation: a video server connected to a progressive monitor.

MPEG-4 Version 2 Digital Cinema CfP
The work of the AHG was reviewed. Several organizations signed the call for test material
response, including Sony, Technicolor, and Paramount. The AHG previewed Sony test material
on VHS (the Technicolor content was previewed on VHS in Beijing) but was unable to view
other test material or view material at native resolution.

NTT volunteered future work to produce (shoot, digitize) content for use by MPEG. They would
pay for the initial costs of production, and the original content would be available for rescanning.
Some of the attributes of the content include:
             10 clips, 10s – 60s each
             35mm film stock
             6500K white
             4096x3112 resolution (10 bit linear)
The work has not been completed but NTT estimates a completion date of the end of March.

Extensive discussion isolated a few test content attributes of high importance for the first round
of tests. These are summarized in N3661.

The test process was refined, specifically the length of most sequences was constrained to <10 s.
The intent was to use using traditional sequential test methods, as these are felt superior to side-
by-side or split-screen viewing for certain artifacts. Split screen viewing was considered but only
for longer sequences (>30 seconds). The test and evaluation process is summarized in N3662.

Test facilities for the subjective tests were proposed at the University of Southern California
(USC) Entertainment Technology Center (ETC) Hollywood Pacific theatre facilities. There is
substantial uncertainty about the facilities, including screen type, ability to fit multiple projectors
or accommodate scaffolding for correct projector placement, air-conditioning, etc. These issues
will be resolved in a future AHG.

Projection systems discussed include a TI-based DLP projector and a Sony CRT-based projector.
There is substantial uncertainty about the DLP projector‟s suitability for the tests due to its low
native resolution, uncertain (digital or analog) interface, and internal signal processing. The
consensus is that multiple projection systems should be considered for the test, but again a future
AHG must determine the specifications and configurability of the projection systems.

Due to lack of much technical information and general consensus that the content and
submissions would not be ready in time to meet the February schedule, the subjective trials were
pushed back to June.

MPEG-4 Version 4 Studio Profile
Initial work was begun to define the schedule for Studio verification tests. A preliminary
template document was prepared for continuing work in the Studio AHG. A final schedule and
verification plan will be available at the 55th meeting.


                                                  87
MPEG-4 Version 5 FGS
Initial work was begun to define the schedule for Studio verification tests. A preliminary
template document was prepared for continuing work in the Studio AHG. A final schedule and
verification plan will be available at the 55th meeting.

Detailed Report

MPEG-7 XM development
Several joint meetings have been taken place during the week between the ISG team involved in
the XM development and the audio, video and MDS groups. Discussions have started with the
MDS group with the review of the current status of the integration of the XM. The main
outcomes of the discussions can be summarized as follows:
Joint Meeting ISG-MDS
It was agreed that comments on the DS normative software are necessary for the understanding
of the normative part of DSs. Templates for providing all relevant information have been
provided by a contribution, it was agreed that DS authors should prepare a comment according to
an appropriate template.
                                               89
Status of new DS submissions promotion from WD to CD and consequently to XM has been
clarified. Some packages are not yet integrated for lack of time between submission and start of
the meeting, some are not yet updated on on the CVS server. More involvement from the MDS
group is required by ISG to help the work to prepare the XM for CD.
Some common problems of submitted code have been explained to MDS group:
1) The structure of the input database and annotated files must be generalized. ISG has provided
a general solution
2) Input format must be a common one Specified interfaces are not used!
3) Several DS defines new classes besides the ones used by the XM and this should be avoided if
possible.
A new schedule is defined for 4 new submissions + one update.
Next version for the final revision of authors will be released by two weeks after the meeting:
Authors will be invited to revise their code according to the comments included by Stephan
Herrmann in each respective code.

Documentation of DS software

Guidelines document is still incomplete (figures are missing, DS specific part are missing) and
has been improved during the meeting, example code are now available.
DS documentation for the XM Template for the comment to DS code.
ISG will present a document describing how to document all submitted DS to be approved by
MDS.
A template table will be provided to guide people to fill information about DS software. A Perl
script will be developed to build a HTML document that will contain all documentation
information, a script need to be done to make an easy update of the documentation.
Template table, and example ready for Friday, output document with two weeks editing time,
then it will be submitted on the reflector to be filled by code submitter.

Joint Meeting ISG-Audio

Contribution M6434 describes the “spoken content” activity in the last 3-4 months. Spoken
content code has been partitioned into normative and non-normative sections according to the
XM structure. These modules are not yet integrated because of lack of time from the submission
and the start of the meeting.
The problem of how to integrate the complex code constituting the extraction component of the
DS was discussed. Audio group does believe that a C/C++ conversion of current extraction
methods would be too heavy. Therefore, the proposed solution is to provide to the XM pre-
computed XML descriptions and generate new ones using XSL. Extraction tools will be available
in MatLab format. A new schedule has been drafted for audio descriptors and DS, 7 new Ds and
6 DSs will be integrated in the XM.
Meeting outcomes about XM development
In conclusion main achievements of the meeting concerning the XM development are:
     The update of Work schedules for the XM integration (video tools, audio tools and DS)
     The update of the status of the XML parsers and their extensions
     The start of the activity aiming at providing a complete documentation of the XM
       software,
     The generation of a template table for the documentation of all Ds and DS to be filled by
       all proposers



                                               90
      The definition of the functionality of a Perl script that can generate automatically an
       HTML document well organized and containing hyperlinks and cross references for the
       XM.
      The new version of the XM guidelines document for the integration with improvement
       and updates of the various APIs

Complexity of video tools

A short discussion was held about the complexity issues raised in the document M6411 “USNB
Contribution: Advanced Simple Profile Issues” A. G. Tescher for USNB. The conclusion was
that the concerns have already been discussed and results are already available in previous
resolutions and contributions from Stockholm and Fribourg meetings.

Reference hardware description for MPEG-4

A proposition to provide a VHDL description of normative and non-normative parts of MPEG-4
has been presented to the ISG group. The comment of the group was unanimously favorable for
the promotion and support of this new activity. The group agreed that a more formal proposition
should be defined discussed and possibly approved during next meeting. A condition that seems
necessary to the success of the activity is that VHDL should be standard portable VHDL. The
benefits of this activity will help time to market considerations for companies trying to deploy
MPEG-4 systems with some hardware components. The current and future complexity of real
time applications of MPEG systems may require a hardware implementation to keep cost and
power manageable. ISG expects there will be benefits especially in the multimedia mobile
market. The ISG group invites universities, companies, and consortiums to contribute towards
the effort. ISG will try to follow the same rules and guidelines as the MPEG-4 C reference
software as far as availability and USge of the VHDL reference code is concerned as a minimum
baseline, but it will try to enlarge the availability and possibility of use of such VHDL reference
code.
