3 ITU-T Workshop on IP/Optical, Chitose 9-11 July 2002 Created in recognition of zthe rapid growth in digital, wireless, and IP networks; zthe convergence of technologies e.g. broadcasting, communications, information technology, etc.; z that multimedia topics are addressed in many SDOs; zthe growth in multimedia services and applications; zthe need to study performance, interworking, inferfaces etc. for user satisfaction. MediaCom 2004 ITU-T Workshop on IP/Optical, Chitose 9-11 July 2002
