Abstract

This paper presents a multimedia communication system supporting group work that exploits the capability of an ATM network system. The system consists of group-work-supporting application software on a workstation and an additional hardware unit that is connected to the external bus of the workstation. This paper begins by presenting the service concept of the system through an analysis of group work and an network properties. Next, it discusses an application software scheme required by the above concept, a multimedia handling that matches its properties, and linkage of group work control and media handling. Finally, it presents the results obtained through implementation of a prototype system which enables multipoint connection through 21 locations and is capable of displaying 11 videos at the same time.
