Scope
This Recommendation specifies a time-division multiplexing (TDM) frame format for adapting multiple Motion Picture Experts Group version 2 (MPEG-2) transport streams (TSs) or generic formats of TSs@ some of which exceed the transmission rate per channel@ into the existing physical layer interface specified in Annex C of [ITU-T J.83]. This format may be applicable to other transmission systems. The frame format aims to multiplex TSs without change@ except that some of the service information (SI) related to the network is replaced. By using this frame structure as an optional addition to conventional digital transmission equipment@ multiple TSs can be multiplexed as they are. The functionality of multiplexing TSs into a single TS is not needed. In addition@ the expansion of the frame format@ being compliant with the first edition (2001-03-09) of this Recommendation@ can provide the functionality for a high-speed transmission scheme by channel-bonding technology. The frame format enables a cable television operator to pack multiple TSs into a single channel or multiple channels. Operation of a cable distribution network would become flexible if services could be integrated on the basis of the TS. This Recommendation provides the information needed by designers and manufacturers of equipment (including receivers) for distributing digital multi-programme signals by cable networks.
