IP Based Video Conferencing System. A comparitive Analysis By R. Sureswaran

2 “Desktop IP Based Multi-point Multimedia Conferencing is positioned to become the next generation form of communications, above and beyond the telephone” (Quote by Industry Analysts) Introduction

3 Traditional/Legacy System Point-to-Point Proprietary

4 Traditional/Legacy System Point-to-Multipoint ISDN running proprietary protocols

5 Problems of today MCS System Requires dedicated ISDN lines to the desktop, which mean additional infrastructure. Expensive MCU (Hub) is needed for mixing and re- transmitting. Expensive WAN link is mostly proprietary and dedicated to video conferencing only. Expensive WAN bandwidth increases proportionally with each new user. * MCS uses your existing LAN infrastructure. * MCS does not need an MCU or any special hardware. * MCS is IP-based and merges with your existing WAN link or uses the Internet. * MCS WAN bandwidth requirements remains constant, irrespective of the number of users

6 Modern MCS Multipoint-to-Multipoint Any IP Network

7 Modern MCS Other Advantages Modern MCS Other Advantages (Cont.) Full Motion Video Conferencing and Video Streaming Up to 40 frames per second Allows unlimited users per conference covering unlimited geographical distances Support for World standards Real Time Streaming Protocol (RTP), Open Systems Architecture and Non-Proprietary hardware requirements

8 Unique features of MCS Multicast enabled for LANs and tunneling for WANs and ATM networks MCS supports all types of networks in the world. Desktop CPU is used minimally for the conference About 16% on a Pentium 300 All entities are open systems and non-hardware specific. Supports full duplex video at true color (64K colors) and full duplex CD quality Audio

9 Unique features of MCS Meetings to be held in a virtual manner directly from your desktop Extremely user-friendly interface Takes 30 seconds to start a conference Minimal cost incurred as the system uses existing network infrastructure Supports any IP Based Network

10 Infrastructure MCS supports all IP-based network architectures including: Broadband Baseband Wireless Satellite

11 RSW Control Criteria MCS Supports the RSW Control Criteria The RSW Control Criteria is an advanced set of controls for Multimedia Conferencing RSW Control Criteria allows up to six different method of control communications MCS has implemented 4 of the 6 control criteria

12 Distributed Network Entities Advantages: Enables Legacy Networks (i.e. Shared Ethernet) to support high-speed multimedia applications i.e. Multimedia Conferencing. Uses the standard IP language for communications A futuristic architecture for high speed distributed processing platforms

13 Distributed Network Entities Advantages: Open Systems Architecture Allows implementation of entities in any OS and programming languages Enables Bi-Directional multicast over ATM and non-multicast enabled routers

18 Compression Entity Provides real-time compression and decompression Particularly useful when bandwidth is an issue, like over the Internet. The compression algorithms used are transparent. Currently, the following are supported: MJPEG, INDIO, MPEG, H.261, YUV411, VDO

19 Implementation MCS is extremely simple to implement The server plugs directly into your network All it needs is an IP address and the IP configuration information of your network Clients are plug-and-play The whole setup usually takes about 2 hours only
