The document summarizes the Multimedia Conferencing System (MCS) which allows for multi-point to multi-point video conferencing over IP networks. MCS uses existing LAN infrastructure without additional costs. It does not require an expensive multipoint control unit and can use corporate WAN links or the internet with constant bandwidth usage regardless of number of sites. Key features include integrated chat, document sharing, multiple resolutions and windows, and compatibility with H.323 video conferencing standard.

1. Connecting the World Multimedia Conferencing System (MCS)

2. Technology trends today indicate that the world of communications is converging. Voice, video and data are all merging into one carrier base : Internet Protocol (IP). Whoever manages to make the above a reality, with the ability to use current infrastructure and generic PCs , will become the world leader in multimedia communications. Technology Trends

3. 1st Generation : POINT TO POINT Legacy Systems Proprietary ISDN

5. MULTIPOINT TO MULTIPOINT to multipoint.. Internet or IP Network Video PABX of the future, where every office can be connected to each other via Intranets or the Internet. Cost of communications: RM 0.00

7. MCS Version 5.0 presents a MULTIPOINT-TO-MULTIPOINT system that has unique features overcome the disadvantages of current systems: Allows multipoint desktop and boardroom conferencing using your existing LAN infrastructure, without effecting your current applications. No expensive MCU is required. MCS uses the non-proprietary IP protocol and runs over your existing network lines and even over the Internet. The required WAN or Internet bandwidth remains constant, no matter how many sites join the conference.
