Abstract
A system of defining, creating and decoding composite virtual channels advantageously supports dynamic channel and event substitution. A method, for use in a decoder for acquiring a program conveyed on more than one broadcast channel, involves generating a program guide display. The program guide display lists programs being broadcast on a plurality of broadcast channels during specified broadcast time segments and also lists a particular program on both a first and a second broadcast channel. The particular program is acquired from the first broadcast channel in response to user selection of either of the first and second broadcast channels. A plurality of prioritized channel maps are used in substituting an alternative program for a first program on a broadcast channel.
