Summary

This amendment provides the contents of Annex B that define a standard for Service Information (SI) on cable compatible with digital multiplex bit streams constructed in accordance with ITU-T H.222.0 | ISO/IEC 13818-1 (MPEG-2). It is designed to support "navigation devices" on cable. It defines the syntax and semantics for a standard set of tables providing the data necessary for such a device to discover and access digital and analogue services offered on cable.

This SI protocol is nominally delivered in a separate physical channel (i.e. out-of-band) outside the actual transport multiplexes containing the program content.
