在视频会议中用到的两大协议分别是：H.323协议和SIP协议，这两种协议各有千秋，在不同的领域占据着不同的地位，通过对这两种协议深入研究，两种协议是对立统一的关系。在此以H.323作为视频会议系统基本框架，深入对MC-Gateway研究，从而设计一个高效的视频会议系统。MCGateway在视频会议系统中主要作用是同客户端进行数据交流，主要执行的是对客户端账号认证和对后台数据库的操作。

The two protocols used in video conference are H.323 protocol and SIP protocol. Each of them has its own merits,and has its importance in different areas. Through in-depth study on the two protocols,it is found that the two protocol have the relation of unity of opposites. H.323 is taken as the basic framework of video conference system. An efficient video con-ference system was designed on the basis of study on MCGateway. The main role of MCGateway in video conference system is to exchange data with the clients,authenticate the client accounts and operate the background database.
