Abstract: This is a research and practice on distributed realtime video conference system based on TCP/IP network. The system is distributed mode and based on the Mbone, the system can make the remote and motive members join a conference. The system implements flow control and multicase technology. It can save much network bandwidth. With several technologies, the critical problem of synchronization between audio and video is resolved. It is very economical since the software plays a main role in whole process. It has great application in China. ;;;;
