ITU-Tís Study Group 9 has
approved an array of Recommendations in several areas including broadband IP
multimedia services and next generation digital set top box architectures.
Group experts say that the advancements will greatly extend the service
capabilities of broadband cable and other networks. The Recommendations were
approved by ITU-T Study Group 9, Integrated Broadband Cable Networks and
Television and Sound Transmission, during its October meeting in Tokyo.
Recommendations include key work in IPCablecom2, modular CMTS (cable modem
termination systems), next generation video set-tops, and architecture for
deploying an IP multicast video distribution network using network layer route
is a project initiated by SG 9 several years ago on time-critical interactive
services over cable television networks using IP. It is a suite of
Recommendations (J.160-178) which provides for telephony, and J.179 (IPCablecom
Multi Media), which creates a bridge that allows for the expansion into a full
range of multi-media services.
is contained in a new suite of Recommendations (J.360-363 and J.365-366) and is
designed to support the convergence of voice, video, data, and mobility
technologies through a modular non-service specific approach. This modular
approach allows operators flexibility to deploy network capabilities as
required by their specific service offerings, while maintaining
interoperability across a variety of devices from multiple suppliers.
Recommendations define an architecture and a set of open interfaces that
leverage emerging communications technologies, such as the session initiation
protocol (SIP), to support the rapid introduction of new IP-based services onto
the cable network. IPCablecom2 is also based on Release 6 of the IP Multimedia
Subsystem (IMS), as developed by the 3rd Generation Partnership Project (3GPP),
which is a SIP-based architecture for providing multimedia services.
