Abstract: A system for acquiring program guide information conveyed on one of a plurality of broadcast channels involves identifying an individual broadcast channel in response to user entry of either of, (a) a first channel identification number (e.g. a virtual channel identification number) and (b) a different second channel identification number (e.g. a transmission channel identification number). The system is tuned to receive the identified individual broadcast channel and packetized program information is acquired comprising a program conveyed on the individual broadcast channel using an acquired program guide. The packetized program information is processed to be suitable for display. The system also supports navigating within a first list of broadcast channels and a second list of sub-channels associated with individual broadcast channels in response to user activation of first and second navigation controls respectively.
