| Abstract: | Video conversation system based on IPTV network is very promising. In the paper a novel video communication system based on IPTV network with QoS guarantee is researched and implemented. The system architecture and service flow chart is first described. Then the design of an embedded IP set top box applicable to the video conversation system is shown and performance optimization method based on embedded system is put forward. Finally a bandwidth adaptive QoS mechanism is brought forward to guarantee user ex... |
