摘　　要：实现了一种基于IE浏览器的组播视频会议:以MicrosoftTAPI3.0(telephonyapplicationprograminterface)COM组件为核心,结合Windows2000ActiveDirectory,采用IP组播技术实现多方通信,大大减少了网络带宽的开销。客户端用户无需安装其它的软件,直接利用WEB浏览器来进行多方的语音和视频聊天。介绍了微软TAPI3.0的体系结构、IP组播会议服务体系和主要模块的实现方法,讨论了会议系统的实际部署问题。A multicast conferencing system based on IE browser is realized, which is implemented with Microsoft TAPI3.0 （telephony application program interface） components, combined with Windows 2000 active directory. The system based on IP multicast to implement multipoint communication requires less bandwidth. People can talk by voice and video on the web browser without installing any other software in client server. The architecture of TAPI3.0 and the service system ofIP multicast conferencing in TAPI3.0 is introduced. Especially the implement method of the main module is analyzed, and the setting-up of system is discussed also.
