Workshops Home Networking and Home Services (17-18 June 2004, Tokyo Japan) http://www.itu.int/ITU-T/worksem/hnhs/index.html - Presentation given by : ITU-T SG 9, SG11, SG12, SG15, SG16, SG17, OSP/IEC JTC1, DHWG(Digital Home Working Group), Digital Homenetwork Forum, MPPA (Motion Picture Association of America), Broadcasting companies and manufactures. - 158 participants from 10 countries - The sessions ·Transport technology · Security · Network Architecture · Quality Services · Content discovery, presentation · Services and Protection

Future Work (I) Broadband Wireless Extensions to IPCablecom Networks Expansion of the scope of procedures for operation of TV and sound-program signals in order to cover other compression bitstreams than MPEG-2 Expansion of the scope of IPCablecom to fully support multimedia capabilities Content protection and digital rights management for cable home networks

Future Work (II) Application Programming Interfaces (API) for use in the secondary distribution of programme material to CATV set-top boxes and to cable “sound radio”receivers Telecommunications over IPCablecom for disaster relief The next generation set-top box (STB) to interoperate with other devices in the home including both IP and non-IP devices

Future Work (III) Extension of cable-based services over broadband in Home Networks ‘Webcasting’(interactive delivery) of sound and TV program over IP networks Quality assessment in multimedia cable networks Measurement of the QoS for TV transmission on contribution and distribution networks Transmission of Large Screen Digital Imagery (LSDI) programmes for contribution and distribution purposes
