ITU-T Workshop on IP/Optical, Chitose 9-11 July 2002ITU-T Workshop on IP/Optical, Chitose 9-11 July 2002
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.

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.
