ABSTRACT:
A multi-point video conference system includes a plurality of terminals and a network. Each terminal includes a coder to code and to packetize at least a motion picture in a block unit and a multi-point video decoder to sequentially receive and to decode packets sent from decoders at other points. The decoder includes a video processor to process video information in a time sharing manner, a channel selection controller to decide a transmission source of a received packet according to information of the packet and to notify the source to the video processor, a shared frame memory to store therein video information from the plural terminals, and a display frame memory to output therefrom the video information in a synchronous fashion.
