Summary

This Recommendation describes a time-division multiplexing (TDM) format for transmission of multiple MPEG-2 transport streams using a simple implementation on cable television systems. The TDM frame encapsulates the MPEG-2 transport streams prior to transmission.

The format features interoperability with the existing conventional satellite transmodulation format, which is designed based on the specification of Annex C/J.83 and Annex C/J.84 (SMATV system C(III)).

This format may be applicable to other transmission systems. Information about the frame format should be transmitted in the network information table simultaneously, when this format is introduced into the existing digital cable television systems. It is needed for the set-top box to identify the digital channel containing multiple MPEG-2 transport streams.
