摘　　要：随着网络技术及多媒体压缩技术的长足进步,提出了基于分组交换网络的视频会议系统.传统视频会议系统中H.323终端不具有扩展性,而MCU的接入能力有限,极大地限制了参与会议的人数.通过对H.323系统及RTSP协议的研究,提出了可扩展的双模终端.系统采用应用层组播技术,以流媒体接入方式改进了H.323终端,实现了终端的扩展,提高了接入终端数量,促进了视频会议系统的发展.With the great development of network technology and multimedia compression technology, the video conference system has been achieved based on switch packet network. The H. 323 terminal of the traditional video conferencing system does not have the scalability and MCU access capacity is limited, which greatly limits the number of people participating in the meeting. Aiming at the problem,a method based on streaming media using the application layer multicast technology is put forward to enlarge the number of terminals through the research of H. 323 system and RTSP protocol. It promotes the development of video conference system.
