Research Abstract

The developed system in this project has implemented required functions that a multipoint bidirectional relay system becomes more scalable and convenience. The system can offer multipoint video communication functions to users by using shared terminals in inter-connected computer networks, which is a basic technology suite to support various kinds of audio-video communication services.
