多媒体桌面会议系统结构

Architecture for multimedia desktop conferencing systems

本文描述了基于客户－服务器模式、面向协同应用的分布式多媒体支撑平台的结构。基于此分层的平台结构，作者给出了一个以联网的ＰＣ机和ＭＳ—Ｗｉｎｄｏｗｓ为硬软件环境的多媒体桌面会议系统的设计。此系统用单一网络综合传输所有媒体信息，除支撑平台外，还包括共享白板、共同编辑、实时语音通信、共享视频以及多媒体电子邮件等分布式协同应用，为分布在各地的用户提供一种坐在自己的办公桌前召开会议，进行同步和异步讨论的环境，这种协作可利用视频、音频、图象、图形以及文本等多种媒体形式。

he authors describe a client-server moded software architecture of supporting platform for distributed multimedia application intended to cooperative work. According to the layered architecture described herein, a multimedia desktop conferencing system is designed using connected PC and MS-Windows. With a unique network for transporting all forms information, the system consists of shared whiteboard, cooperative document editor,real-time audio annotation, shared living video and multimedia electronic mail as well as the platform.
