Annex 4
Requirements report

MPEG-4
MPEG-4 Visual
Level definitions
m7514 Laura Nugent, Viswanthan Swaminathan - Liaison From ISMA to MPEG
m7246 Philippe Gentric - Extending video profiles
At request of ISMA, and after some considerable discussion, the Requirements Group decided to
add a Level 3b for Advanced Simple: It is the same as Level 3, but at twice the bitrate. Unlike Level
4 interlaced video is not supported. The Level is added in an amendment. The group reasoned that
ISMA is an important user group, and that the request should be honored in spite of the fact that it
gives a bit of an outlier in the existing Level structure. Note that that the hierarchy is maintained.
m7484 Ralph Neff - Liaison from 3GPP2 TSG-C: Request for new level of Visual Simple Scalable
Profile
As was already discussed in previous meetings, a Level 0 for Simple Scalable was added at the
request of 3GPP2. This is done in the same amendment as mentioned above.
m7284 The National Body of JAPAN - JNB comments on the new definition of VCV
Following the response of the Japanese National Body to a resolution of the 56th meeting, the
decision was made not to change existing Level definitions.
The group reserved the right to use a different approach for new Levels in existing Profiles, but will
take JNB request into account when this becomes relevant (i.e., new levels are indeed added to
existing profiles)
VTC and arbitrary shape objects
7194 Yuval Fisher, Erwan Le Bras - Proposal for MPEG-4 VTC Alpha Plane
It was decided that an alpha channel to be used with VTC is desirable to enhance the support for
object-based representation of scenes. The alpha channel is added in an amendment.
m7328 Gauthier Lafruit, et.al. - Proposal for modifications to VTC - Preliminary ideas
m7399 Gauthier Lafruit et.al. - Single Configurable Quantization Mode & Simplified Arithmetic
Coding for VTC
The contributions embody interesting ideas on how to simplify the VTC coding. However, the
group felt that the VTC syntax should not be changed in a non-backward compatible ways, and the
proposal would have done that.
Further work on FGS
m7483 Jens-Rainer Ohm - Status of scalable technology in video coding
m7442 Won-Sik Cheong, et.al. - FGS coding scheme with arbitrary water ring scan order
m7393 H.-C. Huang, et.al. - Evidence for improving the existing FGS tool
There was some evidence presented that there may be ways to further enhance FGS performance.
The Requirements Group decided against starting a new work at this meeting, because:
a) Keeping adding tools to the MPEG-4 Visual Standard is confusing for users
b) In spite of demonstrating the use of FGS (and scalability) in general, scalability still needs to
prove its reason for existence in the real world.
36
It was decided that studies can continue in MPEG and that, given continuing promising results, the
issue may be revisited in a year. At that point we will look at the success of scalability in the market
and at the technical results.
Results of tests on new coding tools
Test results warrant new Video Compression work in MPEG. ITU-T SG16 invited MPEG to
collaborate. MPEG is happy with this invitation, and proposes to engage in such a joint
development. Details of the cooperation are handled in the liaison group. The proposed way
forward would not give backward compatibility with the existing MPEG Video coding tool set. The
Requirements Group appreciates concerns from MPEG members that backward compatibility
should be maintained if possible. Therefore, MPEG members can bring, at the next meeting,
evidence that the demonstrated results are attainable while keeping backward compatibility with
MPEG-4 Visual. The Requirements Group also appreciates concerns about extending MPEG-4
from device makers. The message is that MPEG-4 Profile will not be replaced, e.g. in mobile
devices. However MPEG needs to keep up with the state of the art, to suit the need of some of the
other markets. A new standard 4+ years after MPEG-4 Part 2 does just that. We have always
promised that MPEG would act when there was evidence about considerable improvements … and
we are keeping that promise.
Pending these results, the following was decided as a tentative way ahead:
• Start new part of MPEG-4 tentatively part 10 There were discussions as to do this
- As a complete new MPEG (e.g. MPEG-5), or
- As an amendment to MPEG-4 part 2
- As a new part of the MPEG-4 standard
While it was appreciated that the ITU liaisons preferred the first option, it was noted this would be an
anomaly in MPEG, as MPEG always makes complete frameworks. New Systems and Audio parts are not
planned, and in fact MPEG has consistently communicated that MPEG-4 is extensible to include new
coding technologies if and when they arrive. In this sense, it was also felt that starting MPEG-5 would
send the wrong message to the MPEG-4 user community. It was also noted that MPEG-4 part 10 would be
a standard in an of itself.
• Adopt H.26L as starting point, based on the test results.
• Develop jointly with ITU-T SG16, in a process with Core Experiments
• Develop Requirements for the joint project
• Do a study to understand the complexities of the tools in H.26L, with the objective of using that
information for future Profiling activities.
MPEG-4 Systems
7518 Aaron E. Walsh – Updates to Web3D Core Profile
7424 Yuval Fisher, et.al. - Proposal for Level 2 in Advanced 2D Graphics and Scene Graph
After several intense discussions it was decided that there was no consensus for merging of Web2D
and Core2D Scene Graph Profiles. The name Web2D was deemed inappropriate, and has been
changed to Main2D.
Commitments were received for Bitstreams, Conformance definition and Verification Tests – all
being requirements for elevation of a profile into the standard. To be more precise, the policy
henceforth is that bitstreams are needed for:
Exercising All tools in Profile (these can be small)
Exercising the Level to the max (these will be big)
Also, these bitstreams need to have been exchanged (and proven to work) by 2 or more independent parties.
An additional requirement for elevation of Profiles into the standard is the existence of one or more solid
Level definitions.
The following profiles were adopted in the FPDAM
37
Graphics:
• Simple 2D+Text,
• Core 2D,
• Advanced 2D,
Scene Graph:
• Basic 2D,
• Core 2D,
• Advanced 2D,
The following Profiles were considered mature, but not yet adopted in FPDAM:
Main2D Scene Graph: because Level definitions are currently missing
X3D Core Scene Graph and X3D Graphics (VRML interworking point): these have good level
definitions, but bitstream commitments are missing.
It is expected that the requirements for the elevation of these two profiles are met by the next
MPEG meeting, and inclusion in the standard can happen at the next ballot stage (assuming there
are National Body requests for doing so).
Joint with Audio on new Audio Coding Technology
7510 S. R. Quackenbush - Report of AHG on Audio Call for Proposals
7285 Takehiro Moriya, Sang-Wook Kim - Report of AHG on Consideration of Lossless Audio
It was decided that there is currently no need for developing audio coding technology for digital
cinema. Either sound will be used uncompressed, or already available technology (AAC) can be
used to fulfill the requirements.
Some further work on enhancements of MPEG-4 coding is warranted, however. See Audio report.
AFX
7237 Radek Grzeszczuk, et.al. - Standard Support for Progressive Encoding, Compression and
Interactive Visualization of Surface Light Fields
7368 Patrick Gioia - Additions to AFX requirements
AFX requirements were updated using the proposals above.
MPEG-7
MPEG-7 Industry Focus Group
A Special Session was held on MPEG-7 Industry Focus Group. In this meeting, an inventory was
made of the goals of such a group. It was decided that a kick-off meeting would be planned in
conjunction with the next MPEG meeting. The organizers would take it on them to look for
membership and leadership. An MPEG-7 Awareness event is also being planned.
MPEG-7 & different types of content
The Requirements Group had a good and constructive discussion on “distinguishing between legit
and illegitimate content”. It was noted that:
Many tools already in place in either MPEG-4 or MPEG-7
Other tools are upcoming in MPEG-21
The most important missing element is the persistent binding of an ID with content
There is a need to be able to sign Descriptions
o We have a solution now, which could be made more fine-grained
o But before attempting this we need to see what are the requirements.
The work will continue in an AHG.
MPEG-7 Requirements
38
The group defined and refined requirements for MPEG-7/general metadata on MPEG-2. Notably, a
more explicit mention was made of MPEG-7 and its unique features, and that these features should
be supported by the MPEG-2 amendment.
7468 AHG -Report of the Adhoc Group on MPEG-7 binary format
Requirements for BiM, as listed in an annex to the NMPEG-7 Requirements Document, were
refined and adopted in main body.
Again there was a discussion on Profiles and Levels for MPEG-7. Again it was concluded not to
define these yet. We need industry implementation experience before attempting this; MPEG-4 is
taught us this valuable lesson.
The work on Linguistic Modeling: can start; good expert support was demonstrated to execute the
work and we are confident it can be brought to a successful conclusion.

m7463 SMPTE St13-03 - Liaison Input to SC29WG11 from SMPTE (partly)
Using many very useful responses to the Call for Requirements and a week good work resulted in a
consolidated Rights Expression Language and Rights Data Dictionary Requirements Document.
The group chose to keep the requirements document at a high level and not go into the fine details,
to avoid losing the overview and getting bogged down at the evaluation. A three-day pre-meeting
evaluation meeting was planned from 29 November to 2 December in Pattaya, Thailand.
A Call for Proposals was written and issued; the Requirements Document was attached to that CfP.
The CfP mentions the evaluation meeting, and invites submitters to take part. There was a voluntary
pre-registration to help the planning of the meeting.
Technical Report

m7470 Jan Bormans - Draft DoC for ISO/IEC 21000-1
m7472 Jan Bormans - AHG on MPEG-21 Requirements Report
After great preparing work was done during an editorial meeting early June in London, using the helpful NB
comments, approving the MPEG-21 Technical Report was fairly straightforward. All NB comments were
39
disposed of, and the Technical Report was issued with a recommendation to make it available for free from
ISO‟s and MPEG‟s websites.
Other MPEG-21 business
Discussions on a bitstream definition language combined with studies carried out in the Mobile
AHG on content adaptation to specific usage circumstances led to starting a new effort: the MPEG-
21 Digital Item Usage Environment Description. This name is still tentative. A Requirements
Document will be formally started at the next meeting; an AHG is tasked with preparing this
Requirements Document and a Call for Proposals.
There was some debate as to whether this is in competition with the MPEG-7 User Preferences. It
was understood that conceptually the User Preferences could better be in MPEG-21, but that they
serve a useful purpose in MPEG-7 and there is no desire at all to change this situation. Major future
developments, however, should be in MPEG-21. Minor enhancements could still be done in MPEG-
7. The logic here is: MPEG-4 represents the content for reconstruction; MPEG-7 describes the
content; MPEG-21 (among other things) describes the environment in which it is consumed –
including networks, terminals, preferences, etc. The work will take existing standards into account.
Digital Cinema
(Most of this work is reported in the Video Subgroup‟s report). The audio requirements for digital
cinema were updated. The conclusion was that that there is no reason to start new audio coding
work.
IPMP: Current IPMP work should support Digital Cinema. Digital Cinema people are engaged in
the IPMP work to see that this is indeed true.
Further work on requirements for Digital Cinema needs to be carried out at the 58th meeting.
During the discussions on the test result, it was concluded that the link between Archive and
Distribution should not be ignored. How to exactly deal with it was not clear; the DigiCine AHG
would study the issue. The goal is to study upstream generation of content (including film,
computer and digital capture) and the link of (Post) production to Archive and Distribution – and
the link between Archive and Distribution themselves.

M7187, M7191, M7537, M7193, M7203 : Comments of National Bodies on the balloting of the
PDAM were discussed and the DoC was produced. The comments were separated in generic
metadata issues on one hand and in MPEG-7 specific issues on the other. All issues were resolved,
and a FPDAM approved. It is believed that the FPDAM accurately addresses carriage of generic
metadata; however, careful consideration is needed so as to determine whether the FPDAM
provides all detailed functionality that will be required by MPEG-7 applications. The intent is to
study this issue in the October meeting in Washington DC.
M7520 : A method for synchronization between the media content delivery times and the MPEG-7
content description delivery times. Will be considered for extensions of the MPEG-7 standard.
M7274 : New requirements for the carriage of MPEG-7 over MPEG-2 have been added : support of
MPEG-7 metadata, support of the notion of streams, support of random access to these streams.
Solutions to these requirements will be added to the metadata amendment.

M7228 : Amendment 3 to MPEG-2 System defines the Transport Stream Description Table
designed to convey descriptors such as a registration or a copyright descriptor in Transport Stream
packets referenced by the PID value 0x02. The purpose of the Transport Stream Descriptor Table is
to provide Transport Stream-level identification information. Amendment 3 to MPEG-2 System,
however, fails to specify a T-STD buffer model for the delivery of the Transport Stream Descriptor
43
Table. The original intent was to make the Transport Stream Descriptor Table part of the MPEG-2
system information, for which the T-STD is well defined. Consequently, a corrigendum to MPEG-2
System, 2nd edition, is issued to capture this fact.

The general rule for computing these numbers (the number of streams above are estimates) :
- Profile : There shall be at least 2 streams per functionality ;
- Level : There shall be at least 5 streams exercising the limits of complexity of the
level.
All profiles for which there are levels definition are promoted to FPDAM in Sydney. The other
profiles (Main 2D) can be promoted at the next phase if the conditions are met. In particular, levels
shall be defined (NB comments will be needed to elevate these profiles to FDAM).
Promoted profiles: Green.
Profiles that remains under consideration : Yellow.
Profiles definition can be found in N4321(Profile under consideration) and N4268 (14496-
1/FPDAM2).
47
Web Profile
Name of Web Profile : changed to Main 2D.
Quantization : issue pending since complexity of quantization could be a burden for this profile.
Complexity of the quantization will be evaluated with ISG within the BIFS AHG so that a
conclusion can be reached in Washington.
Input Sensors : Main 2D will include input sensor with no restriction.
Insert / Delete node : These commands will be supported without restriction in Main 2D.
Scalability from Main 2D to Advanced 2D : The differences between these two profiles are
TemporalTransform, TemporalGroup. Complexity of these nodes will be evaluated with ISG within
the BIFS AHG so that a conclusion can be reached in Washington. Not only complexity will be
taken into account in the evaluation but also possible differences in terminal architecture.
In case Advanced 2D can not be made a superset of Main 2D, a new profile including the features
not existing in Advanced 2D but existing in Main 2D will be considered. Application requirements
do not necessarily take precedence over complexity
M7518 : Name of the Web3D profile will be updated to X3D Core profile. List of supporting
companies will be updated. The Keysensor functionality shall be integrated with the InputSensor for
the proposal to be fully acceptable.
M7424 : Proposal of a Level 2 in Advanced 2D Graphics and Scene Graph Profiles. Allows much
larger scenes to be included. Allow conversion from Flash. Approved. Will be included in ISO/IEC

IPMP Extensions
The IPMP activity had two meetings since the 56th meeting in Singapore. The first was held in Paris
on June 11-12, 2001. The second was held in Sydney on July 14-15, 2001. Between these meeting,
there was considerable reflector activity that resulted in submissions that were reviewed at the
official meetings. The reports of these meeting are included below as is.
Paris AHG Meeting
Since the 56th MPEG Meeting in Singapore, the IPMP group has had an active correspondence on
the email reflector averaging ten to fifteen messages a day. Eighteen submittal documents have
been authored containing concepts and text for the working draft of the IPMP extension to MPEG.
At the Singapore Meeting, the need for two meetings between the 56th and 57th MPEG meetings
was established and an official meeting was scheduled for Paris in the first part of June.
48
The Paris meeting was arranged by the MPEG Systems Chair, Olivier AVARO, and sponsored by
French Telecom. They provided the meeting room, projection equipment, and lunch for about 30
attendees.
The meeting opened with a review of the areas were work needed to be done on the Working Draft
(WD) of the IPMP Extensions. The main areas of work were identified as the Message Router, the
Message Interface and the Messages themselves. The Ad Hoc Group had produced 19 submissions
covering these areas and some additional areas these submissions had been well discussed on the
email reflector. The submissions covered all the topics discussed on the reflector adequately for the
first time.
Each submitter was requested to present their submission to the AHG. The AHG then decided how
the submission was to be used in the WD. Most of the submissions contained content that will be
directly included into the WD by the editor. This content was cut form the submissions and
appended to the WD for immediate review by the group. Any content that did not have consensus
agreement from the group was discarded. The editor was then allowed to incorporate the remaining
content into the WD after the meeting. The resulting WD was published for review on the email
reflector and the MPEG ftp site.
The disposition of the submittals is contained in the following table:

Several areas need work before the document can go from working draft to committee draft at the
next meeting. These areas are XML representations of the messages, new usage case message
exchange diagrams to assure that we have all the required messages defined, and a review of the
document to see that all requirements have been met.
The reference software status was discussed in detail at the conclusion of the meeting. Craig Shultz
of AccessTicket Systems was appointed editor of the reference software. Spencer Cheng of
Cloakware Corporation volunteered to set up an email reflector for this activity. I volunteered to set
up a web/ftp site to support this effort. These will be announced at the 57th meeting.
Sydney AHG Meeting
The second meeting was held in Sydney on the weekend before the 57th MPEG meeting. There
were 23 additional submittals to be considered. These submittals covered most the areas identified
in Paris as needing additional work. The one area not covered was a review of the document to
assure that all requirements have been met.
The AHG was able to review 18 of the 23 input documents and reach agreement on how they are to
be used in the working draft. The following table summarizes these actions.

discussion of what was needed for the WD to go to CD at the 57th meeting. This discussion will
continue as no conclusion was reached.

Continued work on IPMP Extensions WD
Work progressed on the IPMP Extensions to be included in Amendment 3 to MPEG-4 Systems. In
Sydney, the IPMP working group completed work on the following elements of the MPEG IPMP
Extensions Framework:
IPMP Messaging Interface
IPMP Messages
Tool identification, access and instantiation
Mutual Authentication among tools and terminals
Parametric Tool description framework
The framework is applied in detail to MPEG-4 including syntax and semantics for all the above
elements as well as specific MPEG-4 data routing specifications.
Open issues:
IPMP information synchronization with audio-visual access units
Mechanism for the protection of the MPEG-4 Object Descriptor Stream (following
acceptance of the corrigendum described below).
The IPMP Working Group recommends that this work be included in AMD3 and that this be
promoted to PDAM3 in the final plenary in Sydney.
MPEG-21 Part 4 CD
The IPMP Extensions framework elements have been separated from the MPEG-4 specific
elements of the AMD3 working draft. The resulting document describes only the framework itself.
The IPMP framework elements described above are elements of a framework that is appropriate for
consideration as a general IPMP framework for all of MPEG. It is therefore recommended that the
new document created from the AMD3 working draft be promoted to CD for MPEG-21, Part 4.
52
IPMP Requirements Review
The IPMP working group has begun a review of the IPMP Extensions in the context of the IPMP
requirements included in the Call for Proposals issued at the Beijing meeting, July 2000. The
document will be further harmonized with the extensions with explicit detail regarding what
elements or tools in the specification meet the various requirements.
MPEG-4 Systems Corrigendum
The IPMP working group recognized that the clause in the MPEG-4 Systems specification
regarding IPMP protection of the OD stream is incorrect. The IPMP group therefore created a
corrigendum.
IPMP Issues related to Digital Cinema
M7463 : Issues related to how IPMP Extensions can be applied to the Digital Cinema. See Liaison
report.
MP4 Extensions
The following items have been discussed :
- issuing a draft of the corrigendum (COR2 of MPEG-4 Systems);
- amendment 3 of systems (MP4 version 2);
- M7224 : considered one contribution in joint meeting with audio, problem solved;
- re-write MP4 as mandated by the SC29 AGM;
- met with MPEG-21 to consider requirements and start work.

the proponents. The contribution can be discussed over the BIFS AHG. For technology for which
requirements exist and technology are under study, the technology will be integrated in a core
experiment. The deadline for receiving new input is October 2001. For technology for which
requirements exist and technology are standardized, the proponents shall make a study of the new
technology against the standardized technology with the support of the BIFS AHG. Results will be
made available in the BIFS FAQ.
Requirements for imaged based rendering and multi-resolution surfaces have been added to the
MPEG-4 requirement document.
M7350 : KNB comment :
(1) CFP should address high and low quality apps. Accepted.
(2) Error range should be context/sample dependent. There was a proposal to define the error level
per sample, no consensus. Numerous questions were asked about application space.
(3) Definition of redundant keys. No consensus was achieved.
(4) Propose 3DMC error measure. No consensus was achieved.
54
(5) MFField cannot do all of scope: There was a discussion about adaptive arithmetic coding and its
use. There was mention of the current limitation of the AAC implementation in BifsEnc/IM1. More
than 14 bits should not be necessary, but if so, the implementation may be fixed. Concerns about the
memory usage of the algorithm have been expressed. Again, there was a discussion about
preserving or not the number of keys, and the pertinence of some of the samples. A breakout was
constructive but not conclusive because of the definition of high quality and input sampling for
animation path preserving. There was another breakout to resolve the differences and finalize the
CE text.
M7473: Presented, but difficult to assess before the issues above are resolved.
M7421/M7420: Withdrawn.
M7345: Accepted to go to the multi-user WD with slight modifications proposed by Holger
M7332: The contribution was presented and discussed. Doubt was expressed about the restriction to
have all bookkeepers on the same machine. There was agreement that Proto can indeed replace
SharedObject.
M7200: Withdrawn. Some discussion took place anyway, which led to an agreement to write the
clarifications in sync with Zvi's modifications to the released InputSensor reference software.
M7199: Was presented and discussed, along with two cartoon sequences. No action point is
required.
M7379: No one was present to discuss the contributions at the scheduled time. The contributions
expresses concerns about the InputSensor approach. ENST took the action point to propose a
precise mapping of KeySensor and StringSensor to InputSensor (to replace the current samples
which are incomplete) and publish results well before Washington.

specification. 90 % of the software is already available.
Other issues
Script : the implementation has been cleaned up. There is an issue about the specification of the
language for script. The current reference is in VRML and not everything can be encoding using the
MPEG specification. This needs to be documented. Yuval will make an input document for
Washington.
BIFS Animation : FT R&D will implement this by Washington (Pattaya at the lattest).
Input Sensor : Implemented and will be promoted to FPDAM. The implementation raised some
issues on the specification that have been solved in Sydney.
Media Control nodes : They are implemented. Zvi will test them before uploading them.

Contributions
M7471, M7269, M7403, M7239 : NB comments on 14496-8 CD are reviewed and appropriate
decisions are made. All the changes are integrated to N4282, text of 14496-8 FCD now. Detailed
disposition of comments are recorded in N4281. Major technical comments accepted are as follows;
Terminal requirements to implement generic payload format is weakened. (shall should);
Binary format of IOD shall be used as SDP attribute for MPEG-4 representation
announcement, and textual format based on XMT may be used optionally;
MIME type for IOD is revised appropriately;
Usage of URL in ES_Descriptor is extended to carry binary data.
M7257 : This contribution is proposing a limited and simplified version of generic payload format
as a separate Internet-Draft. This is useful for the case of self-contained ES transport session
without using OD framework. This will be considered as an application notes by IETF and will
result a separate RFC by IETF.
57
M7291 : This contribution contains the questions raised by IETF and appropriate answers. FlexMux
payload format Internet-Draft will be updated soon.
M7289 : This contribution is proposing a modification of 4on2 specification to make BIFS
carouseling more efficient way. However, the problem raised seems to be a general problem of
MPEG-4. This will be further discussed in AHG on MPEG-4 BIFS .
All the latest version of payload format Internet-Drafts and the revision histories from Singapore

FDIS will be finalized in Sydney
m7362 Report of AHG on Metadata Integration
E. Oltmans, P. van Beek, J. Hunter, J.M. Martínez
Reported on the activities of the Metadata Integration AHG. The activities included generating and
applying a software tool for converting MPEG-7 MDS FCD into dictionary. The duplication of names
has been identified (NB requesting to be studied). The potential of using RDF schema for future metadata
integration for MPEG-7 was discussed, but activity lacked critical mass. A report of the was made on the
status of the TV-Anytime Forum development. The recommendation was made to continue work on
dictionary until IS. However, it was not clear whether to continue AHG. Some of the possible future
mandates may be more relevant to Systems (BiM) or Requirements (rights).
m7168 MPEG-7 IPMP AhG Report
Niels Rump (for the AhG)
Report was given on the activities of the MPEG-7 IPMP AHG. The point was raised about where is
the home for MPEG-7 IPMP tools? The AHG Chair suggested MDS. However, Systems may be more
appropriate since encryption/signing wraps description. The discussion was tabled until the joint meeting
with Systems later in the week.

Reported in the status of two core experiments: Abstraction and Instantiation, and
Synthetic Video Editing. A meeting was not held by the CE AHG prior to the MPEG
meeting. No recommendations were made regarding promotion of Abstraction and
Instantiation or Synthetic Video Editing.
m7295 Report of CE on Abstraction and Instantiation
Koiti Hasida, Riccardo Leonardi
Reported on the progress and results of the CE on Abstraction and Instantiation. The CE
evaluated alternative systems for semantic descriptions which claims greater efficiency
than graphs. The CE did not produce complete results. The CE participants proposed to
continue CE.
m7378 Results of CE on Synthetic Video Editing DS
Michel Rynderman, Phillipe Joly
Reported on the progress and results of the CE on Synthetic Video Editing. The activities
included revising the XM software and responding to Editor‟s questions. The CE
71
recommended modifying the referenceType to allow referencing of unique ids that are
outside of document. Alternative solution was raised by MDS Editors to revise semantics
of href in ReferenceType to allow referencing within and outside of description document.

m7247 Issues of Derived Types Instantiation in MPEG-7 Instances
Yuki WAKITA, Takayuki KUNIEDA, Kiyoshi SUZUKI
Issues were raised on Derived Types Instantiation in MPEG-7 Instances. The contribution was related
to JNB16. Issue is the fact that derived subtypes of basic datatypes can appear in locations that are
semantically inappropriate. For example, one can use type “episodeTitle” in the name Name element of a
CreationLocation. Solution 1: Use blocked=#all to prevent derivation of types. This prevents user-defined
derived types. Solution #2 + Put block=#all inside type definition of element. Solution 3: Introduce a new
base level type that is abstract at a higher level. This problem can occur for any of the basic tools. Other
possible solutions were discussed, including: (1) Make derived types anonymous types and eliminate
derived types; (2) Include the needed elements directly where types are derived and do not derive from a
base type; and (3) use model and attribute groups. The recommendation was made for theEditors to
review changes case by case. General issue of base datatype for all Basic tools needs further study.
m7521 Modifications to the Graphical Classification Schemes
Hawley K. Rising III
Proposal was made for developing a specialized MorphismGraph, which is an extension of Graph,
and which describes a mapping between two graphs. This contribution addresses issues raised in USNB
comments 12 through 16 for Chapter 7. It includes a revised section for Graphical Classification Schemes,
some new normative relation for graphical morphisms, and adds new explanatory text. Recommendation
was made to accept the modifications of Graphical Classification Schemes.

sampling. However, those values are ambiguous. The recommendation was made for the color sampling
information to beadopted.
72
m7310 Correction and Extensions to MPEG-7 Coding Formats
João Magalhães (Siemens, SA), Fernando Pereira (IST) for the Portuguese National Body
Proposal was made to improve the classification schemes for MPEG-7 coding formats. The current
format scheme includes nothing about profile@level. For example MPEG-2 for VisualCoding, nothing
about profiles and levels. Added terms to the scheme for all the level and profile combinations. Audio
Coding formats are wrong because they are based on tools not profiles and levels. Some coding schemes
are neither audio nor visual. Add a “scene coding” format and a “graphic format”, and “other coding
format”. The recommendation was made to accept as proposed. Update and add classification schemes
and add new coding schemes to MediaFormat D.

Niels Rump (for the AhG)
The results of the activities of the MPEG-7 IPMP AHG were discussed, including digital signatures
and encryption. The discussion of digital signature and encryption was taken off-line, with the decision to
be taken later in the week as to whether work needs to be done in Systems or MDS.
m7307 UK NB Position paper on ISO/IEC 15938 : MPEG-7 IPMP
UK National Body
The issues were raised pointing out that MPEG-7 currently does not provide a solution for
distinguishing between legitimate and illegitimate content. There has been no technical
solution proposed. May be reasonable to develop a call for proposal since we need to
define specific requirements. This issue will be taken up with Requirements at the chair‟s
meeting.

Ernesto Santos, Todd Schwartz
MPEG-21 WD was presented to MPEG-7 experts for examination of how to use MPEG-7 tools in
MPEG-21 descriptions. The MPEG-21 DiD Editor showed several examples embedding MPEG-7
descriptions in MPEG-21 descriptions. Reference made to W3C Schema adjunct framework.
m7169 MPEG-21 DII&D WD 1.5
Niels Rump, Keith Hill
An approach based on description schemes is being developed for DII&D. Gross
structure of specification has been defined. Individual description schemes are being
73
defined. DIDEF has been removed and will be placed into a separate document.
Questions were raised about how to describe temporal layout (synchronization) and
whether DII&D should specify this, use SMIL, use MPEG-4, or drop. Suggestion was
made to further explore in context of streaming CE.

Mikio Sasaki
Proposes a new tool for version two called a “Characteristic Vector” which is a vector space
representation of the previously proposed Dependency Vector. As well, the axes of the vector are now
represented by Classification Schemes, making it more extensible. The following questions were raised:
Don‟t you need to standardize the dimensions in order for this to be inter-operable? Also, need to
standardize the generation of characteristic vector from descriptions? The decision was made to not
continue this investigation as independent CE or AHG within MPEG-7 but to continue any relevant study
in the context of the MPEG-21 activities on user environment.

Proposes a DisplayPreference DS to specify user‟s preferences for displaying visual multimedia
materials. Includes color temperature preferences for displaying images. Another contribution, M7262,
presents new requirements for display preferences to support this technology. The color temperature
change may depend on the algorithm used. This addresses only one part of display description, shouldn‟t
this be addressed within the larger context of work on terminal capabilities? Is this for MPEG-7 or
MPEG-21? The recommendation was made to discuss in requirements group along with other
contributions on describing terminals.

form AHG to develop requirements for Linguistic Description and to continue CE.
m7306 UK NB Position paper on ISO/IEC FCD 15938-5 : MDS
Ed Hartley, UK NB
The contribution raised the issues of complexity of MPEG-7 descriptions. The decision
from Requirements was made to not look into profiles until evidence is provided about
problems of complexity for terminals. The recommendation was made to draft guidelines
for use of MPEG-7, which may lead to better understanding of issues of profiles. It was
proposed that the document form part 8 of the MPEG-7 standard (Extraction and Use of
MPEG-7 descriptions).
m7490 Relationship between the MPEG-21 and Mediacom 2004 Projects
John Magill, Jan Bormans
This contribution reported on the response to ITU to point out places for collaboration (i.e., Terminals
and Networks; IPMP). Also, point out suitability of MPEG-4 tools for coding. Highlight the concept of
digital item and the framework for declaring, identifying, and describing digital items.
m7275 AHG Report on Describing Terminal Capabilities for UMA
Anthony Vetro, Sherman (Xuemin) Chen, Francisco Rivas
Examined requirements and issues for describing terminal capabilities. Ten requirements were
drafted. Recommendations are that Requirements should determine where the requirements fit (which
standard, which part), and that CfP should be issued, and to continue AHG. Discussion: Rob sees
description of terminal capabilities, user preferences, network conditions, user environment, etc., as a
potentially big effort in MPEG-21. Resolution to continue AHG and continue CE and develop draft of
requirements that could accompany CfP.
m7277 Report of the MPEG-7 Mobile Applications AHG

Resolution to further develop use cases in context of User Environment AHG.
m7262 A Proposal for Consideration of Display Preference in Mpeg-7 Requirements
Youngsik Huh, Yang Lim Choi, Sang Kyun Kim, Du Sik Park
Proposal presented requirements for description of user preferences for tuning of color
displays (i.e., color temperature). Some relevant industry experience was discussed such
as the different tuning of displays for different markets. The recommendation was given
to proponent to further explore the topic of display preference in the context of MPEG-21
in the ongoing work on Usage Context.

m7431 A Draft MPEG-7 Ontology expressed in RDF Schema/DAML+OIL
Jane Hunter
An approach for semantic interoperability for MPEG-7 has been explored which uses RDF schema for
specifying semantics in conjunction with the XML Schema specification of syntax. A framework called
MetaNet has also explored the integration of a number of schema, including MPEG-7, Dublin Core,
INDECS. Study has been made on limitations of XML Schema and RDF Schema for expressing syntax
and/or semantics of schema specification. Proposal was made to express syntax of D and DSs in XML
Schema and express semantics in RDF Schema. Draft was developed that merges RDF Schemas into a
single ontology. A MetaNet has been developed that merges multiple domain-specific ontologies (i.e.,
Dublin Core, MPEG-7, INDECS, ….). So far, draft ontology was developed using top-down approach
using core set of DSs and Ds. The following questions were raised: What is the applicability beyond
MPEG-7 and beyond MDS group? Use of semantic specification? Requires changes to MDS schema
definition? How to collaborate with Semantic Web?.

made: there should not be any automatic disclosure of CEs. Individual companies may disclose as they see
fit. Continue the streaming media CE, now known as “media delivery”: U. Wollongong, NTNU-Ericsson,
LGE (Ian Burnett). Include terminal caps into MPEG-21 CE on streaming media. Streaming media CE
should show usefulness of CHOICE beyond resource variation. Review the MPEG-21 CE Process

The following points were raised regarding DiD:
Need to discuss inline encoding of binary data in DID: use MPEG-7? Or some other
method. It will be base64, as defined in XML Schema Recommendation., need validation
rule for OVERRIDEs in the DID. Paul will provide initial text, need to examine AHG
recommendation wrt ANCHOR reuse, need to make ANCHOR refer-able. Change
NAME attrib to ID, allow it to have REFERENCE child. NAME will also be used for
back-reference, need for ANNOTATION to be able to apply to multiple elements, make
its TARGET IDREFS. Validation: invalidate only for individual invalid targets.
The following points were raised regarding DII&D: need to review Description
requirements in the WD, need to review DIDEF in light of the description requirements,
need new MPEG-21-specific descriptors, consider time synchronization using existing
MPEG-4 sync tools, address legal synchronization: new descriptor, or deal with REL,
discuss ID Resolution System Switcher informative annex, dlarify URN namespace
definition and standard resolution method, need robust transport mechanism, MPEG-21
persistence needs further study, keep the URI approach, rather than narrowing to URN.

During the Sydney MPEG meeting, Video issues were addressed in relation to the following
efforts:
MPEG-2
MPEG-4
MPEG-7
Call for Proposals on New Tools for Video Compression Technology
Call for Proposals for Digital Cinema
MPEG-2
Reports of Problems
A contribution was provided (M7493) that listed some possible problem areas in regard to
MPEG-2 video. This contribution was studied and a study document was produced (N4348)
towards the potential creation of corrigenda to correct any confirmed errors.
MPEG-4
Reports of Problems
Three contributions were provided (M7407, M7256, M7492) that listed some possible problem
areas in regard to MPEG-4 Visual. These contribution were studied and a study document was
produced (N4349) towards the potential creation of corrigenda to correct any confirmed errors.
The Systems group is taking other corrective action in response to one of these contributions
(M7256).
In regard to a prior problem report concerning the VCV design in MPEG-4 Visual, a national
body contribution was provided that advocated not changing the VCV definition for existing
profiles at existing or new levels (N7284), and this view was shared by the group.
85
Document Status Review
The Video group reviewed the evolution of 14496-2, and in view of the need to unify and
simplify the text of the 14496-2 standard to the maximum possible extent, produced a new
unified text for the 2001 edition (N4350) that included the two approved corrigenda and the
original first amendment, and recommended to revise the publication plan for the 2001 edition
status as follows:
Designation FDIS/FDAM Subject
Doc Number
14496-2:2001 N4350 Unified text replacing the 1999 MPEG-4
Visual standard [N2502], the first
corrigendum to the 1999 edition [N3307], the
first amendment [N3056], and the most recent
approved corrigendum [N3664]
14496- N3898 Studio Profile Extension
2:2001/AMD1:2001
14496- N3904 Streaming Video Profiles Extension
2:2001/AMD2:2001
Studio and Fine Granularity Scalability Profiles
a. Verification Testing
Verification tests plans progressed in regard to testing of the Studio and Fine Granularity
Scalability Profiles specified in 14496-2:2001/AMD1:2001 (N3898) and 14496-
2:2001/AMD2:2001 (N3904), respectively. The verification test plans were discussed in joint
sessions with the Test group. New verification test plans for these profiles were approved
(N4292 and N4293). The target date for completion of these tests is the next WG11 meeting.
The Fine Granularity Scalability test plan (N4292) calls for testing of the following tools:
FGS
FGST
and calls for testing of the following functionalities:
Verifying quality over dynamic channels (over a relatively long period), including
operation in the following three model scenarios:
o IP network with priority
o IP network with best effort
o IP network with best effort and error correction
Verifying quality in comparison against Simulcast
The Studio Profile test plan (N4293) calls for testing of the following tools:
4:4:4 chrominance format
10 bit precision operation (this is judged sufficient without additional testing of 12 bit
precision operation)
High bit rate operation (beyond that of MPEG-2 4:2:2 300 Mbits/s)
Lossless coding capability
and calls for testing of the following functionalities:
Multiple dubbing with shift operation
Chromakey processing
Contrast change
86
b. Conformance
No action at this meeting, as the 14496-4:2001/PDAM1 text (N4127) ballot had not been
completed.
c. Reference Software
The work in regard to approval of the reference software for the Studio and Fine Granularity
Scalability profiles progressed to FPDAM status with the issuance of the 14496-
5:2001/FPDAM1 text (N4278) and the associated disposition of comments on the PDAM ballot
(N4277).
d. Ad-Hoc Group Formation
Ad-Hoc groups were formed to progress the work on the MPEG-4 Studio Profile (N4185) and on
MPEG-4 Fine Granularity Scalability (N4186).
Optimized Reference Software
The N4057 draft of the optimized reference software previously intended to be the 14496-7
PDTR was withdrawn due to problems with its production, and instead N4344 was approved as
the proper PDTR text. It includes software for fast motion estimation, fast global motion
estimation, and fast static sprite generation. The draft was promoted to PDTR (N4344).
A study document in relation to the intended disposition of comments received at the Beijing
meeting for a prior PDTR ballot was produced as N4345.
Proposed New Work
a. Proposed New Level (Level 0) of Simple Scalable Profile
A liaison statement was received from 3GPP2 (M7484) in support of a prior proposal for the
addition of a new level (level 0) of the Simple Scalable profile of MPEG-4 Visual. This proposal
was discussed in a joint session with the Requirements group. Since the proposal appeared to
describe a logical and straightforward extension of the existing profile, since industry support for
the new level was shown in the form of the new liaison statement, and since this work appeared
easy to coordinate with other work toward minor enhancements of the existing MPEG-4 Visual
standard, this proposal was adopted and included as the first of three features in the first working
draft of Amendment 3 to MPEG-4 Visual (N4351).
b. Proposed New Level (Level 3b) of Advanced Simple Profile
Several contributions including a liaison statement from ISMA were received advocating the
adoption of a new level of the Advanced Simple Profile of MPEG-4 Visual (M7246, M7514,
M7515). These proposals were discussed in a joint session with the Requirements group. The
contributions advocated the addition of a new level (level 3b) of this profile for support of a bit
rate higher than 768 kbps (the bit rate supported by level 3) without requiring the support of
interlaced video tools (as required by level 4). In order to accommodate the needs of these
highly-committed industry supporters, this proposal was adopted and included as the second of
three features in the first working draft of Amendment 3 to MPEG-4 Visual (N4351).
87
c. Proposed Alterations of VTC Design
A contribution was provided that proposed the addition of an alpha transparency channel
capability to the VTC design in MPEG-4 Visual. This proposal was discussed in a joint session
with the Requirements group. As the new feature design was simple and straightforward and
added significant useful functionality to VTC, this proposal was adopted and included as the third
of three features in the first working draft of Amendment 3 to MPEG-4 Visual (N4351).
Two other proposals were received in regard to alterations of the VTC design (M7399 and
M7328). These proposal were discussed in a joint session with the Requirements group.
However, the group preferred no normative change to the existing VTC design.
d. Proposed Work on Advanced Fine Granularity Scalability
Continued interest was shown (M7393, M7442, and M7483) in the area of investigation toward
new tools for a more advanced form of fine granularity scalability than that currently found in
14496-2:2001/AMD2:2001 (N3904). These proposals were discussed in a joint session with the
Requirements group. It was decided that an ad-hoc group (N4191) should be formed to further
evaluate the potential advancements in this area.
MPEG-7
The following issues related to MPEG-7 visual were addressed:
Review of the National Body comments and ballot results on MPEG-7 Visual CD,
integration and editorial work to address these comments to issue FDIS
Review and Approval of the Visual Ad Hoc Group Recommendations
Review of the input documents and planning of new Core Experiments for version 2
Technical work interface with System
Review of the National Body comments and ballot results on MPEG-7 Visual F CD,
integration and editorial work to address these comments to issue FDIS
All NB comments on the Visual FCD text have been addressed during the meeting. We had 176
comments, from 7NB‟s. Visual FDIS was produced (N4358) and disposition of comments is
included in N4359. Video recommended editorial period till 20 September 2001.
Review and Approval of the Visual Ad Hoc Group Recommendations
All AdHoc group recommendations were approved. 6 Core Experiments established as a result
(see below).
Review of the input documents and planning of new Core Experiments for version 2
6 Core experiments are defined (N4361):
Colour temperature descriptor for display control
Colour temperature browsing
Face recognition descriptor
Camera Parameters Descriptor
3D coordinate system Descriptor
88
CE on BiM/Binary encoding
Technical work on binary coding of visual descriptors (with Systems)
There were many activities between Video and Systems group, discussing the best possible
solution for efficient encoding of visual descriptors. A mechanism to use either generic BiM
encoding or specific visual codes is now provided and supported by visual and system
specifications.
Visual XM Document will be converted to Technical Report, jointly with MDS
Visual XM document contains non-normative but very useful information on aspects of
extraction, usage, properties and features of the visual descriptors. It also includes example
application areas and some indication of performance. Video group decided that it should be
made available to the future users of MPEG-7 standard. Therefore Video and MDS will issue
joint TR with usage information, to become Part-8 of the standard.
Review of the input documents
The following input document were reviewed and appropriate action taken:

Joint meetings with other groups
The following joint meetings were held:
a. Joint meeting with ISG on software implementation.
All Video tools are fully integrated, performance of each tool has been checked by two parties. A
new schedule for software integration was approved.
89
Exploratory Phase Work
Call for Proposals on New Tools for Video Compression Technology
Proposals and demonstrations were provided as a result of the call for proposals of new tools for
video compression technology. Two organizations (the Heinrich Hertz Institute and U. B. Video)
provided excellent anchor reference material for use in these tests, which were conducted at FUB.
Five proposals were received and evaluated in these tests:
– M7178, M7244, M7511, M7512: from ITU-T Q.6/SG16 (the draft ITU-T standard design
known as H.26L), with third-party comments on its design contained in M7277
– M7455: from Univ. Hannover, RWTH Aachen, Robertson Bosch GmbH (based on H.26L
motion compensation, plus modified motion compensation filtering and adaptive block
transforms)
– M7301: from NTT DoCoMo (based on H.26L motion compensation, plus block-adaptive
overlapped block motion compensation and matching pursuits difference coding)
– M7351: from DaViCo (based on H.26L motion compensation, plus overlapped block
motion compensation and wavelet-based difference coding)
– M7408: DynaPel (based on MPEG-4, plus dense motion vector and B-picture blending
fields)
The results of these tests were discussed in joint sessions with the Test and Requirements groups.
The preliminary results (reported in N4240) led to the conclusion that sufficient evidence existed
to indicate that there is new technology that warrants a new standardization effort on video
compression in MPEG. Noting that ITU-T SG16 has extended an invitation to MPEG to jointly
create a new Video Coding Standard, the Video group recommended:
– Starting work on an Enhanced Video Coding Standard, to be developed as a new part of
MPEG-4
– Adopting H.26L TML-8 as the starting point anticipatory joint model (JM), as found in
N4355
– Developing this Standard jointly with ITU-T SG16 as described in a proposed workplan
(N4341), following a process involving Core Experiments; this process can involve
adding, modifying or replacing tools as deemed appropriate by the Joint Video Team
– Developing Requirements for the joint project
– Using expertise in the Video and Implementation Studies Groups to understand the
technical implications and complexities of the tools in H.26L, which understanding can be
used in defining Profiles and Levels
– Encouraging MPEG members to bring, at the next meeting, evidence that the
demonstrated results are attainable while keeping backward compatibility with MPEG-4
Visual
The complexity implications of the proposals were discussed in joint sessions with the
Implementation Studies Group. The tools proposed in response to the call for proposals were
described in a study document that was produced for purposes of supporting later complexity
analysis of these features (N4256).
The Video group asked the WG11 convenor to maintain contact with ITU-T SG16 management
and to bring a final proposal for joint collaboration with ITU-T SG16 to the 58th WG11 meeting.
Two ad-hoc groups were created to further the work in this area:
– An ad-hoc group on requirements for the joint video project (N4183)
– An ad-hoc group on studying enhanced-compression video coding technology (N4189)
90
Call for Proposals for Digital Cinema
Proposals and demonstrations were provided as a result of the call for proposals for Digital
Cinema technology.
a. Digital Cinema Distribution Format Proposals
Sony Corporation provided excellent anchor reference material for use in the distribution tests,
which were managed and administered by FUB.
Five digital cinema distribution format proposals were tested in response to the call:
– M7467: Sarnoff (similar to MPEG-2)
– M7340, M7341: Qualcomm (Adaptive block-size DCT up to 16x16 in size, I-only)
– M7533: QuVIS (2-D wavelet I-only with non-arithmetic entropy coding)
– M7533: MNI (12x12 DCT with new non-arithmetic entropy coding, I-only)
– M7387: Hughes+DemoGraFX (4-Layer difference-domain motion-compensated DCT)
Two additional organizations responded to the call for distribution format proposals but were not
able to be evaluated in the tests:
– M7296: RPI (wavelet I-only)
– M7178, M7244, M7511, M7512: ITU-T Q.6/SG16 (the draft ITU-T standard design
known as H.26L)
The test results were evaluated in a joint session with the Test group. Based on the preliminary
test results, the video group recommended adopting the MPEG-4 Studio Profile as the initial
reference for future work on Digital Cinema distribution.
b. Digital Cinema Archival Format Proposals
Seven organizations provided archival proposals and results:
– M7340, M7341: QCOM (as proposed for distribution, plus Golomb-Rice entropy residual
coding)
– M7258, M7543, M7544: Hughes+DemoGraFX (as proposed for distribution, plus YK
entropy residual coding)
– M7342: Eyelement (wavelet-based with fast Golomb entropy coding)
– M7481: RPI (wavelet-based using quad-trees and bit-plane coding)
– M7533: ISO/IEC JTC1/SC29/WG1 (the wavelet-based feature-rich standard design
known as Motion JPEG-2000, using arithmetic entropy coding)
– M7533: MNI (a new entropy coding technique)
– M7533: Zaxel (DPCM with Huffman coding)
The results reported for the archival format proposals were evaluated in joint sessions with the
Test group. A study of the submitted archival proposals was produced (N4353).
c. Ad-Hoc Group Formation and Future Digital Cinema Workplans
An ad-hoc group was formed to further the digital cinema work until the next meeting (N4154).
That ad-hoc group is requested to propose a plan of action for the future work on both the Digital
Cinema archive and distribution applications.

III. Results of task group activities are reported below.
Record of Audio plenary, joint meetings and task group activities
Audio plenary discussions
Lossless Coding
The members of the Audio subgroup agreed that the next task is to generate requirements that
might be used for lossless audio coding work. We will check with digital Cinema to see if they
are interested in lossless coding of audio.
MP4FF
The Audio chair presented m7224 “Short Audio (again) in MP4.” All audio coding tools have
coded audio frame representations that are self-terminating (i.e. that do not require an indication
of length for successful parsing) with the exception of TwinVQ (which has constant length coded
audio frames). After discussing m7224 and all possible ways that the proposal could be realized,
the Audio subgroup members concluded that MP4FF should adopt a more complex method to
signal access unit length, for example like what is done in the Multi-SL packet MPEG-4 on RTP
IETF draft.
Other Audio plenary discussions consisted of review and approval of work done by the task
groups.
Joint Meetings
Joint meeting with Requirements on Call for Proposals and on Lossless Coding
Rob Koenen met with the Audio subgroup to review the scope of the technology to be
investigated in response to the Call for Proposals and the target performance for accepting that
technology into the MPEG-4 standard (as stated in N3992 from the Singapore meeting). Rob felt
that these were sufficient guidelines for proceeding with this work, and also agreed that the work
was covered by the current MPEG-4 Audio requirements.
For lossless coding, the goals specified in m4010 were reviewed, and he agreed that these were
good goals. He presented the requirements of Digital Cinema in m4046, which are shown under
the “Joint meeting with Digital Cinema” heading.
If PCM itself is used as a representation, the maximum bitrate for audio is (16)(96000)(24) =
36.846 Mb/s.
Joint meeting with Systems on MP4FF
Dave Singer discussed m7224. The goal of the proposal is to make the MP4FF an efficient
container for compressed signal streams. Both the Audio subgroup and the Systems subgroup had
discussed this contribution prior to this joint meeting, so it was quickly agreed that the proposal
in this contribution is not acceptable to Audio. However, Dave Singer immediately made an
alternate proposal, which was that MP4FF Version 2 would support any of 4, 8, 16 or 32-bit
length fields for specifying the length of an access unit. This would reduce the per-access unit
overhead for signalling length to approx. (4 bits)/(8 bits/byte * 5 bytes) = 10%
Other issues discussed are summarized here:
The latest version of the MP4FF library is at the following FTP site: addr: index.apple.com, user:
sc29wg11, pswd: mpeg password and is comprised of two files: iso.zip (the library) and
isofile.doc (documentation). This implements MP4FF Version 1.
93
Apple is happy to take suggestions on how to improve and extend this library. Audio members
are encouraged to contact Dave Singer directly at singer@apple.com. Apple will also consider
putting the library up on a CVS server so that Audio members could actually contribute to the
development of the library.
Joint meeting with Requirements and Video on Digital Cinema audio requirements.
The following is from N4046 (output from the Singapore meeting):
Audio
Requirements for Archive
The standard shall support lossless representation of audio.
The standard shall support up to 16 channels.
The standard shall support up to 96000 samples per second per channel.
The standard shall support up to 24 bits per sample.
Requirements for Distribution
The standard shall support lossless representation of audio.
The standard shall support efficient audibly lossless compression of audio.
The standard shall support up to 16 channels.
The standard shall support up to 96000 samples per second per channel.
The standard shall support up to 24 bits per sample.
Typical rates for archiving are
Video: 500 Mb/s
Audio using PCM: (16 channels)(48000 kHz sampling rate)(24 bits/word) = 18.432 Mb/s
So that audio is approx. 3.6% of the video rate.
The use of audio channels in archiving might be as follows:
7.1 main audio
2 for hearing impaired
2 for visually impaired
1 surround
2 side
1 “ceiling” channel
for a total of 16
Typical rates for distribution are:
Video: 50 Mb/s
Audio: using AAC for compression with 48 kHz sampling rate at a rate of (16)(128 kb/s)
= 2.048 Mb/s
So that audio is approx. 4% of the video rate.
However Craig Todd, Dolby Labs, noted that industry is currently using PCM for distribution of
6 channel audio (via DVD media).
The main conclusions from this meeting were that:
There is no mandate for audio lossless compression in the Digital Cinema application.
The Digital Cinema task group encourages Audio to join their effort.
Audio members are interested in participating as a means of promoting MPEG audio
technology.
Joint meeting with MDS on MPEG-7 Audio Archiving
This meeting occurred, but there is no summary for inclusion in this report.
Joint meeting with ISG on XM integration
94
ISG revised their Status of XM integration table based on advice of Audio subgroup members.
Task group discussions
Call for Proposals
J-B Rault, France Telecom, presented m7324 and M7325, which document the new evidence
brought to the Sydney MPEG meeting. He indicated that the FT AAC core codec used a multi-
pass coding process to iterate to the target bitrate, and that it did not meet the buffer requirements
defined for constant rate AAC bitstreams. The Audio subgroup members noted that the decoder
input buffer requirements must be met (e.g. 6144 bits for a mono signal) in order for the base
coder to be backward compatible. Furthermore, J-B Rault noted that N3992, heading
Comparative Tests, says: “…one test for each of bandwidth extension of general audio signals (at
approximately 24 kb/s)…” thus indicating that the competitive tests will be only at the total rate
of 24 kb/s (and hence mono test items).
M. Dietz presented Coding Technogies‟ view of what an “informative module” in RM0 might be
for their proposed technology. The module identified as informative would be the one that
produces the high-band spectrum based on the low-band spectrum.
The Audio chair summarized the discussions in the Audio Call AhG and further concluded that
the points of contention in the definition of a process were:
Mono vs stereo test items.
Two-pass encoders
Decoders with “informative” modules
Subsequently the group agreed that both mono and stereo test items would be tested, and that the
test would be conducted after the October MPEG meeting. The group further agreed to permit
two-pass encoders, more specifically that there would be no restriction on encoders, only on the
bitstreams that they produce. Finally, a majority of the group, sufficient to be a consensus in the
opinion of the Audio chair, agreed to permit decoders with “informative” modules. However the
informative modules would represent a small fraction of the total decoder and would also be
represented by a “default” normative implementation in source code.
Philips and France Telecom wished it reported for the record that they have asked for a delay
until the next MPEG meeting on the decision as to whether a decoder should have informative
modules. They wish that this matter be discussed in the AhG period.
Discussion on some aspects of the RM0 competitive process was re-visited Friday morning. It
was agreed by the entire Audio group that the following issue will be discussed in adhoc group
period: whether the best system under test or the best fully specified system under test (i.e.
complete decoder source code) determines the technology selected as RM0.
MPEG-2/4 AAC
Corrigenda working drafts for MPEG-2 AAC (Text, Conformance and Software) were prepared.
MPEG-2/4 Conformance
Workplans were set up associated with the AAC conformance test sequences and the ER AAC
conformance test sequences. The status of the MPEG-4 conformance test sequences was updated.
Corrigenda working drafts for MPEG-4 Audio Conformance were prepared.
MPEG-4 Edition 2001
Sang-Wook Kim distributed latest MPEG-4 Audio 2001 draft text to the Sydney meeting
attendees, and members circulated the editor token and prepared the final text considering input
documents m7466 and m7517. Some new bugs were reported in m7466. The task group
discussed how to handle these late bug reports in Audio plenary, and the Audio Subgroup
decided to incorporate editorial changes in MPEG-4 Audio 2001 text, and to prepare a Study on
Text of ISO/IEC 14496-3:2001/DCor1, n4232. The task group noted that a Summary of Editorial
95
Changes to ISO/IEC 14496-3:2001 would be helpful, so the summary text was prepared by task
group members and is available as output document n4231.
MPEG-7 Audio 15938-3
174 comments from 6 national bodies were addressed at the meeting. Of these, most were
disposed favourably. Much of the required editing depends upon the revised status of the MDS
FDIS. In response to comments, a new section entitled Audio Signature has been added,
effectively creating an application centric version of the Spectral Flatness descriptor.
Three input documents concerning new technology were reviewed. As a result, a new core
experiment has been established on audio quality and archiving. One mandate of the core
experiment is to decide which parts of the proposal can already be implemented using MDS
tools. Nevertheless, it seems clear that MPEG-7 Audio will have a second version.
MPEG-7 Reference Software
MPEG-7 reference software was discussed, but there is no summary of that discussion for this
report.
MPEG-7 Conformance 15938-7
Unfortunately there was not sufficient time for this task group to meet.

Discussion
MPEG-4 3DMC extension to animation
There was a contribution document (M7446) stating that the 3DMC in BIFS can not directly
support the animation combined with Interpolators. It was noted that the DEF names are not
carried inside the 3DMC bitstream, hence the association of interpolators with the corresponding
3D mesh object was not possible at the decoder. The problem was acknowledged by the group
and decide to solicit the opinion from BIFS experts in Systems group, while asking the proposers
to bring more detailed input by the next meeting.
MPEG-4 Animation Framework eXtension (AFX)
AFX CE Review:
A2 (Subdivision Surfaces): In this core experiment, two methods are considered to represent
subdivision surfaces: extended loop and extended Catmull-Clark. In addition to the basic
functionality, the core experiment contains the hierarchical coding of subdivision surfaces. All
the related contribution documents are reviewed during the meeting. The core experiment was
not completed at the time and will continue till next meeting.
A4 (Texturing): This core experiment contained matters related to VTC. And there were a few
contributions made to Sydney. Jointly with Video and Requirements group, the discussion
continued. As an integral part of AFX, VTC will be implemented to the AFX S/W package.
A5 (Solid model representation): There was a contribution on the CE. With some application
example with Canadian space project, the proponents also showed that the implementation in
CVS is complete. The decision is made that the basic node definitions for solid models will be
placed in VM. The CE will continue till next meeting where further enhancement on node
definition and implementation are anticipated.
A6 (Mesh Grid representation): Modeling and animation of MeshGrid objects are shown as CE
results. It, however, is noted that animation of MeshGrid objects may be done through existing
framework within AFX. Further study will be conducted till next meeting. S/W implementation
in CVS will be continued till next meeting. All the node definitions will be updated in WD while
the CE is complete.
A7 (Skin & Bone): There was a request to harmonize the syntax between AFX and H-Anim
specifications. Angular parameters are questioned whether Euler angle representation is better
106
than Quaternion representation. There was also a suggestion to support IK in the node syntax.
After a lengthy discussion, the group decided to continue the CE for more study.
A8 (Multitexture): There are currently two small experiments: light field mapping and image
based rendering under the CE. The proposal for light field mapping contained node definition and
corresponding compression within it. Further study will be conducted as core experiment till next
meeting. The proponent has showed capabilities with image-based rendering. How to integrate
IBR into the existing AFX framework still remained as work to do till next meeting.
Verification Model 4.0 & Working Draft 1.0: VM 4.0 has been updated both technically and
editorially (N4221). The working draft for AFX is integrated with MUW in Systems specification
(N4272).
AFX S/W implementation: S/W implementation is a crucial part of AFX development. The
group acknowledged the continuing delay in implementation progress due to the formal release
of Contact3D version 5.0. The interim solution is to use Contact5.0 (executables). Because of
some limitations, there is an effort to change the data repository from CVS. Further workplan can
be found in N4222.
SNHC Homepage review
Some discussion to improve the SNHC homepage has taken place. New version of home page is
expected to appear before next meeting.
SNHC Presentations
The group found that most contribution are presented by electronic presentation materials. Hence,
it is decided to collect the materials during the meeting and to make them available in the SNHC
homepage (http://www.sait.samsung.co.kr/snhc).
SNHC FAQ update
FAQ 5.0 of SNHC was reviewed by SNHC members and got fixed with new Q&As (N4018).

Test group report
Source: Vittorio Baroncini
During the 57th MPEG meeting the test group presented the preliminary reports of the formal
tests on “Responses to Video Call for New Tools to Further Improve Coding Efficiency” and on
“Responses to Digital Cinema Call for Proposals”.
The results of both tests are described in the documents N4240 (Coding Efficiency) and N4241
(D-Cinema). For the time being these documents were not considered to be ready for final
approval.
The Test group made also progress in the definition of the final schedule for the test plan of the
Visual Fine Granularity Scalability Tools Verification tests. Document 4292 describes the detail
of the test plan and schedule. The results will be available at the next MPEG meeting.
Finally the final test schedule has been also defined fro the MPEG-4 Studio Profile verification
test, for which also results are expected by the next meeting. Document 4293 describes the detail
of the test plan and schedule.

Detailed Report
MPEG-7 XM reference software development
Four joint meetings have been taken place during the week between the ISG team involved in the
XM development and video, MDS, audio and Systems groups. Discussions have started with the
Video 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:
109
Joint Meeting ISG-Video
The status of the integration of video Ds has been analyzed. Almost all Ds are fully integrated,
documented and verified. Commitments have been taken to provide within two weeks the only
two missing software modules. Two new phases have been defined to upgrade the software to
FDIS status, software modifications and software verification, both these two tasks will be
completed by the end of August. Two contributions proposing the generalization of the “Dummy
Type interfaces” M7355 and M7356 have been discussed and they will be resubmitted at next
meeting after that the impact of the current XM implementation and the advantages provided by
this new interfaces will be verified.
Joint Meeting ISG-Systems
Bitstream tools known as BiM and interfaces for the formatting of MPEG-7 streams into access
units are not yet ready for integration in the XM. Such tools are still in a stage of code
verification and debugging. The BiM Systems group agreed on the necessity to integrate the
tools in the XM. ISG explained the philosophy of the XM architecture and the motivations to
integrate BiM tools in the key applications supported by the XM. The group committed to study
the Reference Software FCD to understand the correct integration of the tools and the to verify
the necessity of developing appropriate interfaces. The System BiM group committed to provide
a list of tools and a draft work-plan for the integration before next MPEG meeting.
Joint meeting ISG-Audio
Audio group informed ISG about the recent submission of Ds and DSs concerning the main so
called client and server modules developed in Matlab. Still missing are the extraction tools and a
few main modules for which submission is committed for the next meeting. Glue component as
well as documentation will be provided by the same date. Commitments are taken to revise the
code according FDIS status and to verify the correct functioning of the code.
Joint ISG-MDS
Status of the few missing modules has been clarified and commitments for the submission of glue
components and the few documentation modules have been agreed. End of September and end
October have been agreed for the final update of software to FDIS and the corresponding
software verification.
Editing of the “Study of ISO/IEC FCD 15938-6 Information Technology -Multimedia
Content Description Interface- Part 6: Reference Software”
A part of the meeting was dedicated to draft a DoC document answering to the Japan and US NB
comments on the MPEG-7 FCD reference software text. The associated study document will be
issued at next meeting after an appropriate editing period.
Meeting outcomes about Reference Software development
In conclusion main achievements of the meeting concerning the Reference Software development
are:
The update of Work schedules for the XM integration (video tools, audio tools and DS)
including the new steps “code update” according to FDIS, and “final verification”.
The initial draft of the Study of the MPEG-7 Reference Software FCD, including
modifications asked by NB comments.
Reference hardware description for MPEG-4
110
The call for the expression of interest for part 9 Reference Hardware Description has raised the
invoice of 10 expressions of interest from companies and universities. The ISG has asked for a
commitment of maintaining the received submissions on an FTP site and Xilinx has kindly
accepted to act as collector and support for the activity. Therefore ISG has recommended starting
such activity and has issued a call (document N4218) for the submission of reference hardware
VHDL code. Conditions for the submission and recommended format of the VHDL code are
clearly described in the call.
Observation of exploratory activities for possible complexity analysis tasks
During a joint meeting with video group it was discussed how to proceed for the complexity
analysis of the new exploratory activity for improved coding efficiency. It was clarified that
complexity analysis should be focused on precise objectives. Therefore it was agreed that first
video group would have proceeded with the definition of core experiments to select the various
candidate tools starting with as baseline the last evolution of H.26L. Then complexity analysis
would be used to select tools of similar coding efficiency performances versus complexity of
decoding and encoding. In a second stage, when the new baseline resulting from core
experiments would be sufficiently stable, complexity analysis will be performed to evaluate
overall complexity and compare it with the current extended simple profile.
