SG 9 at a glance (Study Period 2009 - 2012)

ITU-T Study Group 9 - Television and sound transmission and integrated broadband cable networks

This page refers to a previous study period. For its most recent version, please see here.

ITU-T Study Group 9 carries out studies on the use of telecommunication systems for broadcasting of television and sound programs and furthermore the use of CATV networks to provide interactive video services, telephone and data services, including Internet access.

Work highlights

Among recent work are ITU-T Recommendations on Voice, data and video IP applications over CATV networks (IPCablecom), interactive cable television service, high-speed data services, and IP-based television, video distribution (IPTV service).

Study Group 9 has created ITU-T Recommendations in the area of next generation cable modems which act as universal integrated receivers or set-top-boxes for home networking. Such devices will link all types of electronic devices for applications such as entertainment, telecommunication, information technology, home automation systems and telemetry (remote control and monitoring systems).

To smooth the progress of world wide exchange of interactive TV services, Study Group 9 has also developed a harmonized set of interactive content formats and common application programming interfaces (APIs), capable of providing the variety of functionalities required by advanced interactive applications, to be delivered over TV networks to end users’ homes.

Furthermore, SG9 is looking at Large Screen Digital Imagery (LSDI) which is described as an optimal approach to the presentation of super high definition television (HDTV) programs to a collective audience on cinema-like screens in a cinema-like environment.
