1.1 项目立项依据

视频会议是通过通信网络把两个或多个地点的多媒体会议终端连接起来，在

其间传送各种图像、话音和数据信号，使出席会议者有亲临现场的感觉。视频会

议系统还应用于远程教育、远程医疗等需要传送实时音频、视频和数据的业务。

信息技术的发展推动了视频会议技术的发展，美国“911”事件的之后，视频会

议系统得到迅速普及和大范围应用。

视频会议能为用户提供直接和实时的沟通交流，可节约会议时间和降低成

本。国内外很多科研机构和厂商都进行了多媒体多点会议通信系统的研究，并推

出了各自的视频会议系统。在研究各视频会议系统的基础上，国际电信联盟

(ITU-T)形成了视听多媒体通信系统国际标准的H.320及 H.323系列标准，使不
