System for acquiring and processing broadcast programs, program guide and channel identification data
View Patent ↗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.
1. In a video decoder, a system for tuning to acquire packetized program information comprising a program conveyed on one of a plurality of broadcast channels identified by a physical transmission number corresponding to a virtual channel and a virtual channel identification number of said virtual channel including a major number associated with an information provider and a group of sub-channels and a minor number identifying a sub-channel from among said group of sub-channels, comprising the steps of:
navigating within a first list, including a plurality of broadcast channels, to identify and select a broadcast channel and an associated virtual channel identification number, in response to user activation of a first navigation control, wherein the physical transmission number corresponding to said virtual channel identified number is displayed with said virtual channel identification number;
navigating within a second list of a group of sub-channels associated with said selected broadcast channel to identify and select a sub-channel and an associated minor number, in response to user activation of a second navigation control;
tuning to receive a selected broadcast channel using said selected virtual channel identification number; and
acquiring packetized program information comprising a program conveyed on said broadcast sub-channel using said minor number.
2. A system according to claim 1 , wherein
said first navigation control comprises a control for incrementally or decrementally traversing through numbered broadcast channels, and
said second navigation control comprises a control for incrementally or decrementally traversing through numbered sub-channels.
3. A system according to claim 1 , wherein
said first and second navigation controls use the same user activated remote control unit button.
4. A system according to claim 1 , wherein
said first and second navigation controls use different user activated remote control unit buttons.
5. A system according to claim 1 , wherein
said first navigation control comprises a control for incrementally or decrementally traversing through a displayed menu listing numbered broadcast channels, and
said second navigation control comprises a control for incrementally or decrementally traversing through a displayed menu listing numbered sub-channels.
6. A system according to claim 1 , including the steps of
generating a displayed menu listing numbered broadcast channels incrementally or decrementally traversed in response to said first navigation control, and
generating a displayed menu listing numbered sub-channels incrementally or decrementally traversed in response to said second navigation control.
