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

Modern MCS Other AdvantagesModern 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

Unique features of MCSUnique 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 MCSUnique 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

InfrastructureInfrastructure MCS supports all IP-based network

architectures including: Broadband Baseband Wireless Satellite

RSW Control CriteriaRSW 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

Distributed Network Distributed Network EntitiesEntities 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 Distributed Network EntitiesEntities 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

Compression EntityCompression 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

ImplementationImplementation 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
