P.A.Probst, Swisscom SA

Chairman SG16/ITU-T Multimedia Services, Systems and Terminals


Created in recognition of

the rapid growth in digital, wireless, and IP networks; the convergence of technologies e.g. broadcasting,

communications, information technology, etc.; that multimedia topics are addressed in many SDOs; the growth in multimedia services and applications; the need to study performance, interworking, inferfaces etc.

for user satisfaction.

MediaCom 2004



Objective:

MediaCom 2004

to create a framework for the harmonized and coordinated development of multimedia communication standardization for use across all ITU-T and ITU-R Study Groups, and in close cooperation with other regional and international SDOs and industry forums.

Conclusions:Conclusions:

Coordination and harmonisation in the development of standards for convergence services IT/Telecommunications is under way

Urgent need to progress in the coordination and harmonisation in the development of standards for convergence services Broadcasting/IT/Telecommunications

MEDIACOM 2004 of SG16 is the umbrella for this activity in the field of services and applications

The workshops represent an excellent opportunity to progress in the understanding of the work in this field and to coordinate the work of our respective entity with other SDOs and involved organisations.
