  2. MediaCom 2004 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. ITU-T Workshop on IP/Optical, Chitose 9-11 July 2002

  3. MediaCom 2004 Objective: 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. ITU-T Workshop on IP/Optical, Chitose 9-11 July 2002
