Abstract :
The multimedia-board is a CSCW application in long-distance education and a key technology to realize long-distance classrooms and real time multimedia answering systems. In order to meet the requirements of large-scale users´ cooperation with real time multimedia in an IP network, the paper presents the concept of multimedia-board and the definition of a multimedia-board system. It goes on to describe a conversation model with a Petri net and provides a concurrent control mechanism and algorithm which may be applied to the multimedia-board and other CSCW systems. Finally, the authors present the design of a multimedia-board with B/S structure and its perspective in practice
