摘　　要：设计ＣＳＣＷ系统结构的关键问题是如何提供有效的协作支持．本文提出了一个分层的协作支持方案．此方案包括三层：面向系统，面向应用以及面向共享对象的协作支持．相应于这一方案，本文还提出一个可容纳多种协同应用，并基于公共平台的ＣＳＣＷ系统体系结构．通过对这三层协作支持的实现，多媒体桌面会议系统ＴＨ－ＭＤＣＳ可借助视频、音频、图象、图形、文本等多种媒体形式方便有效地支持分散在各地不同专业领域的小组成员同步或异步地完成各种协作任务．The main issue in designing the structure for CSCW systems is to provide efficientcollaboration mechanisms. We propose here a hierarchical collaboration mechanism scheme whichconsists of three levels:system-oriented,application-oriented and operation object-oriented collaboration support. In accordance to this hierarchical collaboration mechanism,we explore a platformbased architecture of CSCW systems that can accommodate multiple cooperative applications. Withproviding all of the three-layer cooperation mechanis ms, multimedia desktop conferencing systemTH-MDCS can support geographically separative group members which are of different fields,seated at their desks,cooperating at the same time or at different time by means of sharing information in such multimdia forms as video,audio,image,graphics and text to carry out various taskstogether.
