Research On Desktop Sharing Cooperative Design Systems Under Low-Bandwidth Condition

With the development of CAD systems and Computer Supported Cooperative Work (CSCW), people are searching for new technologies to combine them together to develop brand-new Computer Supported Cooperative Design (CSCD) systems. CSCD systems based on desktop sharing have the advantage of"What You See Is What You Get", and robustness. Besides, they support heterogeneous software environment, that is, they don't require the participants install the same software's. But desktop sharing systems require a high bandwidth to transfer the screen image, so this paper digs into the key technologies of desktop sharing systems under low-bandwidth condition. More attention is paid to how to reduce the bandwidth using. The following technologies are covered by this paper.First, compression of screen images; cooperative design systems require...
