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.

Study 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.

SG 9ís 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 diversity.

IPCablecom 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. 

IPCablecom2 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.

These new 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.
