| 摘 要： | H.332协议是H.323协议的扩展,它是一个分布式松耦合结构视频会议系统的规范.基于IP组播技术,采用MicrosoftDirectShow组件,研究并开发了一套符合H.332标准的视频会议系统.系统通过采用RTP/RTCP协议等技术,缓解了音频视频数据包的丢失、延迟和音视频同步等问题,保证了视频会议的服务质量.由于系统是纯软件实现的,因而大大节省了成本,具有一定的实用价值.

| Abstract: | H.332 protocol, which is the extension ofH.323, is the criterion of distributed loosely-coupled video-conferencing. Adopting microsoft sirectshow, such a system is researched and developed based on IP multicast. Packet-lose, delay and synchronization of audio and video are alleviated by using RTP/RTCP, and quality of service ofvideo-conferencing is guaranteed. It is very economical since the software plays a main role in the whole system, and it has some value in application. |
