摘要
IP组播 (Multicast)桌面视频会议系统采用领先的概念和技术 ,有效地利用了 IP网络资源 ,通过音 /视频流单一拷贝的组播 ,大大减少了对带宽的消耗 ,也减轻了发送端的负担 ,同时使终端能够方便地加入和退出会议。我们采用 Microsoft公司的TAPI3 .0开发包 ,实现了一个 IP组播桌面视频会议系统 ,能提供良好的音 /视频多点通讯 ,同时集成了 Net Meeting会议组件 ,实现了完整的 T.12 0数据会议。本文介绍了 IP组播会议模型、系统的设计 ,给出了主要功能的实现方法 。
Video conferencing system based on IP multicast takes many advantages, such as less requires on bandwidth, ease of the management of the conferencing We have developed an IP multicast video conferencing system with Microsoft's TAPI 3 0, which is a powerful tool for developing H 323 and IP multicast video conferencing systems This paper introduces the architecture of TAPI 3 0, specifically the architecture of IP multicast conferencing How to realize the multipoint conference is discussed, and also including the deployment of the system on actual network
