Method and apparatus for transmitting and downloading setup information
View Patent ↗Multiple channel maps are embedded in a television transmission and the appropriate channel corresponding to the particular television service used by the viewer is downloaded for use with the television receiver. Each channel map is accompanied by a channel map identifier which identifies the source of the television transmission and a geographic identifier. The source of a television transmission is automatically detected by monitoring the radio-frequency spectrum allocations of telecast stations. The geographic area identifier is determined by comparison with a user inputted geographic area identifier. The channel map having a channel map identifier corresponding to the detected television transmission source and the user inputted geographic area identifier is downloaded and stored for future use.
1. A method performed by a user equipment for determining a mapping of channels to stations at a specific geographic location, the method comprising:
receiving signals of a plurality of channels;
receiving a geographic area identifier;
scanning the signals of the plurality of channels to generate channel map information, the channel map information including respective information corresponding to a plurality of geographic area identifiers;
determining the information of the channel map information corresponding to the geographic area identifier;
determining a channel map identifier based on the determined information; and
determining a channel map corresponding to the channel map identifier, the channel map mapping each of the plurality of channels to a corresponding station of the plurality of stations for the geographic area corresponding to the geographic area identifier.
2. The method of claim 1 , wherein the determining the channel map corresponding to the channel map identifier comprises:
searching the signals of the plurality of channels to find a data block having the channel map identifier; and
extracting from the data block the channel map.
3. The method of claim 1 , further comprising storing the channel map into a memory.
4. The method of claim 3 , further comprising waiting until the user equipment is not in use to store the channel map into the memory.
5. The method of claim 1 , wherein at least one of the signals contain data packets that are divided into data blocks.
6. The method of claim 1 , wherein the determining a channel map corresponding to the channel map identifier comprises receiving a user input of one of the plurality of channels.
7. The method of claim 1 , wherein the geographic area identifier is a postal directory code.
8. The method of claim 1 , wherein the channel map is used to schedule a recording of programming.
9. The method of claim 1 , wherein a channel map packet is used to determine the channel map identifier based on the determined information.
10. The method of claim 1 , wherein at least one of the plurality of stations comprises a call letter.
11. The method of claim 1 , wherein the signals are television signals and wherein the plurality of stations are a plurality of television stations.
12. A user equipment for determining a mapping of channels to stations at a specific geographic location, the user equipment comprising:
means for receiving signals of a plurality of channels;
means for receiving a geographic area identifier;
means for scanning the signals of the plurality of channels to generate channel map information, the channel map information including respective information corresponding to a plurality of geographic area identifiers;
means for determining information of the channel map information corresponding to the geographic area identifier;
means for determining a channel map identifier based on the determined information; and
means for determining a channel map corresponding to the channel map identifier, the channel map mapping each of the plurality of channels to a corresponding station of the plurality of stations for the geographic area corresponding to the geographic area identifier.
13. The user equipment of claim 12 , further comprising:
means for searching the signals of the plurality of channels to find a data block having the channel map identifier; and
means for extracting from the data block the channel map.
14. The user equipment of claim 12 , further comprising means for storing the channel map into a memory.
15. The user equipment of claim 14 , further comprising means for waiting until the user equipment is not in use to store the channel map into the memory.
16. The user equipment of claim 12 , wherein at least one of the signals contain data packets that are divided into data blocks.
17. The user equipment of claim 12 , further comprising means for receiving a user input of one of the plurality of channels.
18. The user equipment of claim 12 , wherein the geographic area identifier is a postal directory code.
19. The user equipment of claim 12 , wherein the channel map is used to schedule a recording of programming.
20. The user equipment of claim 12 , wherein a channel map packet is used to determine the channel map identifier based on the determined information.
21. The user equipment of claim 12 , wherein at least one of the plurality of stations comprises a call letter.
22. The user equipment of claim 12 , wherein the signals are television signals and wherein the plurality of stations are a plurality of television stations.
