Multipoint Interactive Audiovisual Communication

Objective

The objective of this project was to develop a system for the simultaneous communication of speech, images and data between persons at two or more widely separated locations, using ISDN and other 64 Kbit/s networks.
The objective of this project was to develop a system for the simultaneous communication of speech, images and data between persons at two or more widely separated locations, using integrated services digital network (ISDN) and other 64 Kbit per second networks. A demonstrator was developed in a real environment, made up of a multipoint international audioconference system with visual and office system aids, interconnected using terrestrial and satellite links. The signal and protocol structure developed is applicable to a wide range of other audiovisual services, and has been adopted as part of the CEPT audiographic teleconference recommendation (T/N31-02). The conferencing system was successfully demonstrated in multipoint mode between 8 European locations in April 1988. The demonstration included high quality speech, chairman's control and meeting aids.

The conferencing system was successfully demonstrated in multipoint mode between eight European locations in April 1988. The demonstration included high-quality speech, chairman's control and meeting aids (facsimile, SPTV, telewriter). A follow-on project in this area, MIAS (project 2684), is further developing this system in the areas of ISDN and multimedia facilities.
