ITU-T J.183 PDF

The scope of this Recommendation is the definition of a time-division multiplexing frame format to adapt the multiple MPEG-2 transport streams into the existing physical layer interface specified in Annex C/J.83. This format may be applicable to other transmission systems.

The frame aims to multiplex transport streams without change except that some of the service information (SI) related to the network are replaced. By using this frame structure as an option to the conventional digital transmission equipment, multiple transport streams can be multiplexed as they are. The functionality of multiplexing transport streams into a single transport stream is not needed.

Implementation of this frame format enables the cable television operator to pack multiple transport streams in a single channel. Also, the flexibility on operation of cable distribution network would be obtained if the integration of services could be achieved by the transport stream basis.

This Recommendation provides the information needed by the designers and manufacturers of equipment (including receivers) for digital multi-programme signals distributed by cable networks.
