Multipoint Interactive Audiovisual System

Objective

MIAS is a project in the field of multipoint audiovisual telecommunications. Until recently, the various telecommunications services have used different networks and equipment. Thus text might be sent by telex, and the spoken word by telephone. At the time of the project, there had been little attempt to combine these services together. Thanks to digital transmission and switching, we are now starting to see a variety of audiovisual services which combine sound communication, pictures and text in a number of ways. So that these terminals can interwork, however, it is important that a standard framework is provided which describes how the signals are combined and controlled. This framework is generally known as the conversational audiovisual service infrastructure.

The main objective of MIAS has been the further development of this signal and protocol infrastructure, building on the results already achieved in this area by the preceding project 1057-MIAC. The adoption of such an infrastructure as a European and world-wide standard is enabling the successful introduction of terminals and services based on these concepts.
