Cable Virtual Channel table [ATSC Syntax]

When a broadcaster desires to use different channel labeling or numbering (or both) between cable and terrestrial broadcast, or when a broadcaster has coordinated consistent channel labeling and numbering with all local cable operators carrying that multiplex, the Cable Virtual Channel may be used.

When both CVCT and TVCT are present in a transport stream, receiving devices are expected to use the TVCT to navigate services received via terrestrial broadcast and the CVCT to navigate services received via cable.
