摘要： 把ＣＳＣＷ技术结合到远程教学中，设计实现ＴＲＣＥＳ（ＷＷＷ－ｂａｓｅｄ Ｒｅｍｏｔｅ Ｃｏｏｐｅｒａｔｉｖｅ Ｗｏｒｋ Ｓｙｓｔｅｍ）。ＲＣＥＳ采用了Ｂ／Ｓ模式实现，使用户不必安装专门的软件就可使用系统。ＲＣＥＳ系统中的实时交流工具多媒体电子白板也是ＣＳＣＷ系统的主要工具。为了实现交互功能，设计了一套控制传输协议（ＣＴＰ），它是应用层协议，用Ｊａｖａ和ＪＭＦ来实现它。系统提高了实时交互能力并实现了多媒体信息，特别是时基媒体的实时传输。

Abstract: Computer Supported Cooperative Work (CSCW) is combined into the remote education, and the WWW-based Remote Cooperative Education System (RCES) is designed and realized in the paper. RCES adopts Browser/Server model and makes users able to run the client over the Internet without the need of installing special client software. And the real-time communication tool in RCES - multimedia whiteboard is also designed and realized which is also the major tool of CSCW A set of Control Transport Protocol (CTP) is proposed to transmit the data and realized with Java and Java Media Framework (JMF). The new system enhances the interaction capability and realizes live transmit of multimedia data including graphics, images, audio and video etc.
