The ITU-T Recommendation J.203-2006, the common core for Digital Video Recorder Platform
was based on the work of the DVB and Cablelabs that was published as an informative document,
by the DVB. Since that time, ETSI has published a revised and updated version [1]. The present
document will amend and update Recommendation J.203 to be in accord with [1].
The present document defines a modular extension to ITU-T Recommendation J.202 [1], and
updated as GEM [2], which defines how the recording and playback of digital video (and audio)
content is integrated with the GEM [2] platform. The present document is firstly intended to be used
by entities writing terminal specifications and/or standards that extend a GEM [2] terminal
specification with digital video (and audio) recording and playback. Secondly it is intended for
developers of GEM [2] applications that wish to use digital video (and audio) recording and
playback. Implementers should consult the publisher of specifications which reference GEM [2]
regarding conformance.
NOTE: The present document defines the interfaces visible to applications. Application
developers should not assume that any related interface is available unless it is specifically
listed. Terminal standards or implementations may have other interfaces present. One of
the primary goals of the present document is to maximize the common aspects concerning
the integration of digital video / audio recording between MHP [3] and the various GEM
[2] terminal specifications.
