MCU’s
Overview

A MCU (Multipoint Control Unit) is a net component that allows that three or more end users join the same multipoint conference. It is in charge of video and audio process and transfer. To carry out its functionality, a MCU use to be composed of two different modules:  MC (Multipoint controller). It provides control functionalities to allow videoconferences between two or more end users. It is the videoconference controller and it is in charge of avoid MCU malfunction due to an excess of tasks. In this sense, MC negotiates the videoconference parameters (bandwidth, frame rate, bit rate, etc…) with the end users involved in order to provide the best quality to this session. MP (Multipoint processor). It gets the incoming video, audio and data streams to process them as needed and configured so it functionality depends on the chosen MCU configuration.



Moreover than this two modules, many MCUs provides the platform with an extra module called DCS (Data Collaboration Server). This module allows the data communication between end points to share user applications as a document, some slides, a chat or even the full desktop.

6.2

Considered architectures

The main goal of this chapter is to analyse the possible functionality and configuration of a MCU in the HDViper project platform. They are many questions about the level of integration with a MCU and the way of how a MCU should work so an study of these possibilities must be carry out.

6.2.1

MCU-proxy using an SVC codec

The objective of SVC is to enable the encoding of a high-quality video bit stream that contains one or more subset bit streams that can themselves be decoded with a complexity and reconstruction quality similar to that achieved using the existing H.264/MPEG-4 AVC design with the same quantity of data as in the subset bit stream. To describe the full operative of this process is not the goal of this document so, if more information about it is needed, it could be found at “http://en.wikipedia.org/wiki/Scalable_Video_Coding”. This kind of MCU works receiving a single HD-SVC stream from each end user and sending the treams to end users like a proxy.

page 20 (36)

Available hardware analysis

6.2.1.1

Pros

Thanks to SVC, the MCU good reduce the size of a video and with it the needed bandwidth by not sending all refinement streams to a particular user. It means that, in a heterogeneous network, end users bandwidth might be utilized more efficiently since it can be different bandwidths for each participant, with no extra codification process. The MCU can negotiate with client applications and send only a specific number of the refinement streams.

6.2.1.2

Cons

Some partners experience with implementing a SVC codec, stated that this solution works fine in theory, but in practice it is very difficult to implement and, also the bandwidth needed for the SVC stream in much higher than for a standard H.264 stream to get to a worst quality as each user must send a full SVC stream, with all refinement streams. In fact If the total bandwidth of a SVC stream (all layers) is compared with the bandwidth need by a high performance non-scalable codec (e.g. H.264), the SVC will be significantly higher. Moreover, a MCU that gets one full quality HD stream for each user and then decides what to send to the other users is needed.

6.2.2

MCU that recodes all streams.

In this case, the MCU decodes all incoming video streams, lays out the video windows, codes it as one stream and sends it to the end user. That means that MCU is mixing incoming video streams and sending result to all participants (the same one stream to every terminal). Using a recoding MCU, each user sends and receive just one HD stream to and from the MCU.  2008 CELTIC participants in project HDVIPER

Available hardware analysis

page 21 (36)

6.2.2.1

Pros

This solution provides some benefits that must be taken into account. The first one, and also the most relevant ones is that, if the MCU recode the video streams and send them together in one stream, the needed bandwidth is reduced in comparison to sending all HD video streams separately to end users. Also, this solution reduce the end user terminal costs as it only will receive one video stream. It means less computational needs and less bandwidth restrictions. Another important benefit of this solution is that it makes easy the implementation of the videoconference recording requirement as the videoconference can be recorded as one stream before the MCU recodes the incoming video streams. It will take less hard disc space to store it.

6.2.2.2

Cons

This would be a very nice solution but, in spite of the need of a market research, it seems that this solution is the most expensive one as the needed MCU must be a powerful machine. Also, a MCU which decodes every HD-video (around 30Mbps) and encodes all together in a mixed video in real time must be found. With this solution, the original video streams must be scaled down at the MCU from 1920x1080 to 960x540 (or from 1280x720 to 640x360), in order to fit up to 4 video streams onto a single HD screen.

6.2.3

MCU-proxy receiving to separate HD and SD streams from each user

Now, the MCU works like a proxy, forwarding the incoming video streams to the end users as needed. That means that MCU is not mixing anything, but acting as a multiplexor resending some incoming video streams to end users, with a configured rule.

 2008 CELTIC participants in project HDVIPER

page 22 (36)

Available hardware analysis

With this approach, the way of work is that each user sends two separate streams, one HD and one SD to the MCU. Using this point, if an end user wants to see a full screen video, the MCU proxies would chose and send an HD stream but, if the user wants to see many participants, the MCU forwards all the SD streams.

6.2.3.1

Pros

Once again, a market research is needed but it seems that a MCU of this kind could be really more cheaper than a recoding MCU and also less powerful machine is needed.

6.2.3.2

Cons

It requires more upload bandwidth for each user.

6.2.4

RTP Proxy

Now, the MCU works like a real proxy forwarding all incoming streams to all end users. That means that MCU is not mixing anything, but acting as a multiplexor resending incoming video streams to end users. In this approach, the end users will send one HD stream to the MCU and will receive as many streams as end users are connected to the videoconference.

page 23 (36)

6.2.4.1

Pros

One more time, it is needed to look for an MCU with this functionality but it seems to be the cheaper solution as the MCU does not do any activity over the streams.

6.2.4.2

Cons

Using the MCU only as a multiplexer and sending all the HD streams to every end user, will put to high demands on the end users hardware and on the end users bandwidth. Also, and again in terms of client side equipment, a forwarding solution means one HD screen per video stream (if a "continuous presence" is required). Moreover, a MCU which can receive and send every HD-video (around 30Mbps for each one) in real time must be found and the needed bandwidth for the MCU connection would be really high.

6.3

Needed functionality

In this chapter should try to gather together all the functionality that an MCU must provide to became a candidate to be part of the hole HDVIPER platform. Moreover, the best and achievable scenario of the MCU configuration, must take into account the hardware capacities of the MCU, the end user terminal and network bandwidth. The wished requirements that the chosen MCU should fulfil are the followings: 1. 2. Files and other still images should be shared between several users so MCU must provide a functionality to allow this sharing process. Each MCU user should send short text messages to all participants that should be displayed on each participant’s screen. This solution came up to have a universal and unified solution for text communication which can be used to send information that is available all the time during the videoconferencing session to all participants. When the automatic recording option is enabled the MCU records the sessions in the videoconferences using the default layout. It should be possible to get the number of connected users to each MCU session. Tools to upload, browse and download files associated with a MCU session must be provided. It should be possible for each user to browse the files associated with the current videoconference. Files are described by their names, file type and upload date. The right to browse files and archives must be given only to those end-users who have access to the MCU conference to which those are attached. It should be possible for each user to get a list of the videoconference participants. A way to see the name of a participant in one picture must be provided.

3. 4. 5. 6. 7. 8. 9.

10. Any user should be able to point and mark parts of the current picture and also to draw a fixed-width free-form line on the picture and it should be visible for all participants. 11. MCU should allow that up to ten end users participate simultaneously in each meeting. 12. There should be a possibility of establishing a secure (encrypted) videoconference. 13. There should be protection against spam and against virus calls. 14. MCU will work as a proxy for data services (file sharing, presentations, document editing). 15. Each MCU room must be identified by a name and should has its own configuration, recorded conferences archives and associated files.

A single multipoint meeting can accommodate up to the total capacity of the system, which supports 36 video streams (1 plasma display = 1 video stream), so 12 Cisco TelePresence 3000 systems, 36 Cisco TelePresence 1000 systems, or a mix of both can participate in a single meeting. Every stream needs a FULL-HD display to show every flow, so there's no down sampling or reencoding the different streams to generate a new stream with the combination. Moreover, a mosaic or any other layout where every video becomes smaller causes a missing of presence feeling.

Conclusions

From the point of view of the end users application, he MCU should be treated as a normal end client. This means that if we implement communication standards, like SIP, this will enable us to incorporate any MCU that also has this standards implemented. Additional services, services specific for the HDViper, could be implemented separately from the MCU (SOA). To choose one of the four options described in this document, first of all it is needed to discuss if HDVIPER can be focused only in one of them or on as much as possible. It's interesting to analyse which is the best solution to use in HDVIPER. It seems that a mixing MCU or forwarding MCU can be a "different configuration" so a product with both behaviours would provide a perfect solution for HDViper platform. On the other hand, a recoding MCU would be a very nice solution if not for the price of such solution. There are not many MCU on the market which support HD recoding and they are very expensive so it was mentioned that due, to the cost, this idea will not be used in HDVIPER. So the open issues now are if there is any commercial solution that meets HDViper requirements and also to decide what can be realistically goal within the project. A mixing solution will be very complex, whereas a forwarding MCU is rather simple (an RTP reflector like the one used by Alkit with Confero will do the trick). HDViper does not have resources to develop a video-mixing MCU within the project, so an existing products with HD support must be used, and those are not abundant. If a mixing solution is chosen, clients may as well transmit standard definition video which is not really the focus of HDVIPER. So, if project efforts are used to develop a really good HD video client application, multipoint feature can be achieved with a little additional effort by using an RTP reflector and, if the extra required bandwidth can be provided by network operators, would be the next question.

Computers

There are some steps that need to be followed before providing a list of computer vendors which can provide a BOX to be deployed. First, it is mandatory to know in detail which are the requirements that need to be fulfilled. Then, it is possible to find individual elements that provide the required functionality. And, at the end, a list of vendors can be provided.

9.1

Theoretical requirements

The first step consists on determining which element are required to fulfil the project requirements. The BOX needs to perform different tasks, but the main characteristic is that must be able to encode and decode H.264 in real time. Some constraints can be determined based on the H.264 standard definition, the following list is chosen for the worst case considered. That is a resolution of 1920x1088 at 30,1 frames per second:      Baseline profile: although some other profiles could be used, this one is specially focused on real time coding. Maximum of 4 stored frames: even when there is more memory available, no more frames will be stored. Maximum of 8192 macroblocks per frame. Maximum of 245760 macroblocks per second: this value is the result of the relation between the maximum macroblocks per frame and the frame rate. 8 bit sample depth: this is the defined value for baseline, extended and main profiles.

9.1.1

Memory

This previous constraints allow to determine some theoretical values for the memory needed to store and display the video information:     Minimum memory: this is the minimum memory that should be available in the system for processing the video signal. 4 frames * ( 1920 * 1088 ) pixel / frame * 8 bit / pixel = 66846720 bits  8 mega bytes Memory throughput: this is the amount of memory that system should be able to use in a second. 30,1 frames / second * 8192 macroblocks / frame * ( 16 * 16 ) pixel / macroblock * 8 bit / pixel = 504994201,6 bit / second  60 mega bytes / second

9.1.2

CPU

Unfortunately, it is not possible to determine theoretically how many MIPS are required based on H.264 general data. This parameter is directly related to the code implementation because the standard only specifies which are the operation required to decode a standard video signal.

9.2

Recommendations

REMARK: The following information cannot be verified and, therefore, it is a recommendation that may not be accurate with the expected results. This information can only be tested when the software is fully developed. Even it was not possible to determine exactly which are all the standard requirements for a computer to process correctly H.264 video signal, there is some hardware that could be used within the project to fill the requirements.

Available hardware analysis

9.2.1

Memory

Current computes usually provide 2 GB of memory running at 667 or 800 MHz, which improves greatly the minimum theoretical requirements to work with H.264. Therefore memory should not be considered as a critical point when deciding whether a BOX is suitable or not. Even when it is not a requirement, memory speed could go up to 1066 MHz for a greater performance whenever it is possible.

9.2.2

CPU

Although it is not possible to obtain the theoretical data for this requirement, some other vendor have already tested their solution with different CPU. The following is some examples on two vendor’s experience. Vanguard Software Solutions provide a SDK with encoding and decoding functions and state the following quote: “A minimum requirement for SD (720x480) live H.264 encoding would be Pentium-4 3.0GHz or a Core2Duo system. The decoding side is less demanding: any modern system will suite (Celeron, P4, Core Duo or higher). Full HD (1920x1080) can be viewed on a Core2Duo 2.0 GHz PC. Full HD real-time encoding is already feasible on Intel Xeon QuadCore systems!” According to their experience, normal computer systems with a Core2Duo processor can perform correctly except when encoding Full HD video. There is also a comparison of MPlayer encoding of a video sample of 720x448 @ 30000/1001 fps with target bitrates of 900kbps, the testing machine was an AMD-64 3400+ at 2400 MHz in 64 bits mode. Some functionality was disabled depending on the required quality providing different number of frames as a video output, the result can be seen on the table below: Output Quality Very high quality High quality Fast encoding FPS (higher is better) 6 fps 13 fps 17 fps PSNR (lower is worse) 0 dB -0.89 dB -1.48 dB

It is not possible to extrapolate this values to higher resolution, but this table provides a view of lowend system’s performance. Even it is rather at the edge of technology, it seems to be possible to encode and decode real-time H.264 with the latest powerful Quad Core processor. An example for this technology would be the Intel Core 2 Quad Q6600 working at 2.4GHz with a price around 300€ or the AMD Phenom 9600 working at 2.3GHz with a price around 250€. If it comes to a lower performance because lower resolutions are used, an Intel Core 2 Duo processor could be a good option with a lower price. Other powerful CPUs (Quad Core also) could be also taken into account::    Core 2 Extreme QX6700 (around 600€) Core 2 Extreme QX9650 (over 1000€) Core 2 Extreme QX9775 (over 1500€)

Graphic card

Although processing is normally performed in the CPU, it is important to off-load it as much as possible in order to have a greater encoding performance. This can be easily achieved with current GPU on market that provide hardware acceleration when decoding H.264 video signal. The major manufacturers have developed different solutions: ATI has AVIVO and nVidia has PureVideo. Both of this technologies provide hardware acceleration that can lower CPU usage from 75% to 25% when decoding H.264. On ATI side, we can find the Radeon HD 2600 with prices ranging from 100€ to 200€ depending on the card vendor. A similar situation can be seen on nVidia side with the GeForce 8600 processor.

Both manufacturers have already higher end devices with prices over 500€ like the GeForce 8800 and the Radeon HD 2900, and are also developing newer series like the GeForce 9 or the Radeon HD 3000 one. But although this devices will provide greater performance, it is not sure if whether they will be capable of lowering more the CPU usage or not.

9.2.4

Other elements

Any other standard element in state-of-art computers should perform correctly within the project requirements, but it is important to remark some specific needs:    HDMI output: displaying device can be connected through other interfaces like SCART or DVI (using an adapter) but a direct HDMI connector would be a better choice PCI-Express: current graphic cards use this connector and it is already built in on most mother boards PCI-Express or PCI-X: motherboard must provide enough connections to include the capturing card in the system, the connector type will vary depending on the card chosen to capture the camera’s signal

9.3

Available computer

Although no specific computer has been foreseen for this comparison and only individual recommendation have been issued, two recommendations have been issued for the most important components within the project requirements which are the CPU and the GPU. Concerning the GPU, the devices are starting to include H.264 decoding using hardware acceleration and are evolving rapidly by providing new controllers that could make change the final recommendation. But at the moment, it seems GeForce 8600 card provides a slightly better performance than the Radeon HD2600. Concerning the CPU, the Intel Core 2 Quad Q6600 offers a good performance even it is not sure that can encode real time 1920 x 1088 resolutions. If this higher resolutions are not used, a Core 2 Duo processor could also be a good option. In case the choice is to acquire the latest high-end device, the recommendation would go up to the best CPU (currently the Core 2 Extreme QX9775). It is not possible to state which would be the performance improvement without testing both systems, but it should show some improvements. At this moment it is not recommended to improve the graphic card because the GeForce 8600 is the best one that supports nVidia PureVideo HD technology. But probably this technology will be included in future versions of high-end graphic cards. This changes would increase the total price of the computer from around 1000€ to much more depending on the chosen upgrades.
