Multimedia Multipoint Teleteaching over the European ATM Pilot

In this paper, we present the design and implementation of the BETEUS (Broadband Exchange for Trans-European Usage) communication and application platform. BETEUS is a European project aiming at developing generic, stable, flexible and scalable communication and application platforms which provide support for a collaborative work environments. In terms of collaborative work, BETEUS concentrates on distributed classroom, tele-seminar, multimedia document archival and retrieval and tele-tutoring. The problems found during the realization of the BETEUS platform are outlined and the proposed solutions explained. The follow-up of BETEUS in Switzerland through the TELEPOLY project which concerns operational teleteaching between the two Swiss Federal Institutes of Technology (EPFL and ETHZ) is also presented.
