APAN Multimedia Working Group

Charter

Objective:To support and encourage research and development

of multimedia applications that support/need the usage of high bandwidth networks.

Activity:The First Goal of the Multimedia Working Group is to

formulate our target projects. These targets will be based on the expertise of the members and their research areas.

APAN Multimedia Working Group Applications (Distributed Multimedia Architecture)

INFRASTRUCTURE

– Multimedia supported IP over ATM • Most supported and well developed protocol• Important to integrate well with ATM

– Distributed Multimedia Support• Enhance performance of Legacy Networks

to support Multimedia

APAN Multimedia Working Group Applications (Distributed Multimedia Architecture)

Distributed Multimedia Support

• Currently Being Researched Intensively by Researchers worldwide.

• Distributed Network Entities is an architecture invented and successfully implemented by USM’s Network Research Group.

APAN Multimedia Working Group Applications (Distributed Multimedia Architecture)

Distributed Network Entities

Currently Defined and Implemented Entities Include:

– The Server entity– The Client entity– The MLIC entity– The Compression entity

APAN Multimedia Working Group Applications (Distributed Multimedia Architecture) - MLIC Entity

• The MLIC (Multi LAN IP Converter) entity enables Multicast Messages to be sent over non-multicast enabled networks and routers. (99% of Routers and Networks are non-multicast enabled)

• MLICs transform a regular network into a multidirectional multicast enabled network

• No adjustments or changes need to be made to the network. (ie MLIC does its job transparently)

APAN Multimedia Working Group Applications (Distributed Multimedia Architecture) - Server Entity

• Communicates with all entities to synchronize and coordinate the system

• In the case of the MLIC, the server provides the routing table for the MLIC

APAN Multimedia Working Group Applications (Distributed Multimedia Architecture) - Client Entity

Performs the following functions:

• Multimedia captures --> capture audio and video information

• Multimedia playback --> display of audio and video

• Data packetization (for transmission) & Data reconstruction (for receiving).

• Communication with the server to maintain the RSW Control Criteria.

APAN Multimedia Working Group Applications (Distributed Multimedia Architecture) - Compression Entity

The function of the Compression Entity is to:• To provide real-time compression and

decompression• Particularly useful when bandwidth is an issue,

like over the Internet.• Compression algorithms used are transparent:

Currently, the following are supported:

MJPEG, INDIO, MPEG, H.261, YUV411, VDO

CODEC Bandwidth (Kbit/s)

Bit Encoding Rate = 75 Bit Encoding Rate = 50

1. MJPEG 26.6 17.1

2. Indeo R 3.2 23.0 16.2

3. Microsoft

72.5 23.9

4. Indeo 4.3 25.2 N.A.

5. Indeo 5.03 26.3 N.A.

6. VDOnet 14.0 12.0

The above are some test results with different compression algorithms.

Implementation

• The Multimedia Working Group plans to

implement the Distributed Networks Entities

Architecture on the APAN Network

• High quality Multipoint Desktop Video

Conferencing which utilizes this architecture will

be its first application.
