Recommendations providing architecture for advanced set-top boxes have been
approved by Study Group 9.
Recommendations (J.290-J.292) take into account advances in technologies and
architectures for delivery of multiple types of services – including video,
voice and data. The three include a core Recommendation along with two adjuncts
which provide for a cable solution and a media independent solution. The core
document (J.290) describes key functional aspects of the next generation
set-top box (STB), such as configurable security including downloadable
conditional access, advanced codecs, video over IP, QoS control and extension
of these functions to in-home networks.
describes the cable network architecture component of the next-generation STB.
When combined with companion Recommendation J.290 the architecture defines a
cost-efficient platform with capacity and flexibility to support growth of
on-demand video, high definition digital TV, managed in-home networks
connecting a wide range of consumer-provided devices, and future IP multimedia
services including IP voice, video telephony, and multiplayer gaming. It
reflects key functional aspects of the next generation cable STB, such as a
common application platform (globally executable MHP (Multimedia Home
Platform), which is the common core among OCAP (OpenCable project), MHP and
ARIB (Association of Radio Industries and Businesses), MPEG (Moving Picture
Expert Group) transport including advanced compression technology, and
downloadable conditional access (configurable security).
describes a core architecture that is not dependent on transport media for a
next generation STB which will allow service providers to offer existing and
new advanced services regardless of the transport media. In this Recommendation
it is assumed that all contents are transported on IP packets with an adequate
QoS controlled mechanism. The Recommendation reflects key functional aspects of
the next generation STB, such as network resource adaptability, secure two-way
authenticated communication and session resource management and a QoS-control
