Method and system for acquiring electronic programming guide signals
View Patent ↗A system and method for use in a cable network to acquire electronic programming guide (EPG) content signals from one or more EPG vendors. The system includes a set-top box (STB) for receiving cable signals and EPG signals from a headend controller so that the STB can output the signals to a media output device for display. A conversion table is provided to each STB for use by the STB in determining source IDs associated with a given channel for each EPG vendor, the source IDs for use in acquiring the EPG content signals.
1. A method comprising:
sending, from a first computing device and to a second computing device, a first channel map associated with a first channel map provider;
sending, from the first computing device and to the second computing device, a conversion table comprising a portion of the first channel map mapped to a plurality of source identifiers associated with a second channel map provider different from the first channel map provider; and
sending, from the first computing device and to the second computing device, an instruction to switch from using the first channel map provider to using the second channel map provider via the conversion table.
2. The method of claim 1 , further comprising:
generating the conversion table, the conversion table comprising a first set of channel numbers for the first channel map and a second set of channel numbers for a second channel map associated with the first channel map provider.
3. The method of claim 2 , wherein generating the conversion table comprises:
mapping the first set of channel numbers to a first set of the plurality of source identifiers; and
mapping the second set of channel numbers to a second set of the plurality of source identifiers where the first set of channel numbers has at least one channel number different from a respective channel number of the second set of channel numbers.
4. The method of claim 2 , wherein generating the conversion table comprises:
indicating that each channel number of the first set of channel numbers corresponds to the first channel map; and
indicating that each channel number of the second set of channel numbers corresponds to the second channel map.
5. The method of claim 1 , wherein the instruction prompts the second computing device to recognize a non-use channel portion of the first channel map, wherein the non-use channel portion identifies the second channel map provider.
6. The method of claim 1 , wherein the instruction causes the first channel map to become inactive for determining source identifiers.
7. The method of claim 1 , wherein the conversion table comprises a channel number of the first channel map provider mapped to a particular source identifier of the second channel map provider, and wherein the channel number and the particular source identifier are associated with a same call sign.
8. A method comprising:
sending, from a first computing device and to a second computing device, a conversion table mapping a first set of channel numbers associated with a first channel map of a first channel map provider to a set of source identifiers associated with a second channel map provider different from the first channel map provider; and
sending, from the first computing device and to the second computing device, a change channel map provider signal instructing the second computing device to use the conversion table.
9. The method of claim 8 , further comprising generating the conversion table by:
mapping a second set of channel numbers associated with a second channel map of the first channel map provider to another set of source identifiers associated with the second channel map provider.
10. The method of claim 9 , wherein the conversion table comprises an identifier of the first channel map mapped to the first set of channel numbers and an identifier of the second channel map mapped to the second set of channel numbers.
11. The method of claim 9 , wherein the change channel map provider signal identifies the second channel map provider.
12. The method of claim 8 , wherein the change channel map provider signal causes the first channel map to become inactive for determining source identifiers.
13. The method of claim 8 , further comprising:
sending, from the first computing device and to the second computing device, the first channel map associated with the first channel map provider.
14. The method of claim 8 , wherein the conversion table comprises a channel number of the first channel map provider mapped to a particular source identifier of the second channel map provider, and wherein the channel number and the particular source identifier are associated with a same call sign.
15. A method comprising:
receiving, from a first device and by a second device, a first channel map associated with a first channel map provider;
receiving, from the first device and by the second device, a conversion table that maps a portion of the first channel map associated with the first channel map provider to source identifiers associated with a second channel map provider different from the first channel map provider; and
in response to receiving a change channel map provider signal, using the conversion table to access the source identifiers associated with the second channel map provider.
16. The method of claim 15 , further comprising:
prior to receiving the change channel map provider signal, using the first channel map to access source identifiers associated with the first channel map provider.
17. The method of claim 15 , further comprising:
determining to use the source identifiers associated with the second channel map provider based on a non-use channel of the first channel map.
18. The method of claim 15 , further comprising:
retrieving media content using the conversion table.
19. The method of claim 15 , wherein the conversion table comprises a channel number of the first channel map provider mapped to a particular source identifier of the second channel map provider, and wherein the channel number and the particular source identifier are associated with a same call sign.
20. The method of claim 15 , wherein the conversion table comprises a first set of channel numbers of the first channel map and a second set of channel numbers of a second channel map associated with the first channel map provider.
