Terrestrial Virtual Channel table [ATSC Syntax]
Terrestrial Virtual Channel table sections convey basic information about virtual channels in the transport stream and optionally, other transport streams. The program_number field provides linkage to the appropriate Program Map table section, and source_id field provides a link to the appropriate Event Information table section.

For terrestrial stations, a TVCT is a mandatory PSIP table that lists all the virtual channels available in an ATSC transport stream, and optionally, virtual channels available in other ATSC transport streams.
This page was last modified on December 3, 2009, to correct the name of the table as listed in the caption, to include the value "transport_stream_id" in the table section header, to correct the semantic value of that field, and to change the links for those corrections.
