Method and apparatus for selecting among multiple tuners
View Patent ↗A system or method selects among multiple tuners to tune a particular channel. A request is received to tune a first channel. In response to this request, a first tuner is assigned to tune the first channel. A request is received to tune a second channel. If the program tuned by the first tuner is not being recorded, the first tuner is assigned to tune the second channel. If the program tuned by the first tuner is being recorded, the second tuner is assigned to tune the second channel.
1. A method comprising:
receiving a request to tune a first channel;
assigning a first tuner to tune the first channel;
receiving a request to tune a second channel;
assigning the first tuner to tune the second channel if the program tuned by the first tuner is not being recorded; and
assigning a second tuner to tune the second channel if the program tuned by the first tuner is being recorded, wherein assigning a second tuner to tune the second channel includes determining whether a second tuner is available for tuning.
2. A method comprising:
receiving a request to tune a first channel;
assigning a first tuner to tune the first channel;
receiving a request to tune a second channel;
assigning the first tuner to tune the second channel if the program tuned by the first tuner is not being recorded;
assigning a second tuner to tune the second channel if the program tuned by the first tuner is being recorded; and
assigning a third tuner to tune the first channel if the first tuner is unable to tune the first channel.
3. A method comprising:
receiving a request to tune a first channel;
assigning a first tuner to time the first channel;
receiving a request to tune a second channel;
assigning the first tuner to tune the second channel if the program tuned by the first tuner is not being recorded;
assigning a second tuner to tune the second channel if the program tuned by the first tuner is being recorded; and
assigning a third tuner to tune the second channel if the second tuner is unable to tune the second channel.
4. A method comprising:
receiving a request to tune a particular channel;
determining whether a second tuner is available for tuning;
assigning a first tuner to tune the particular channel if the program currently tuned by the first tuner is not being recorded; and
assigning the second tuner to tune the second channel if the second tuner is available for tuning and the program currently tuned by the first tuner is being recorded.
5. A method as recited in claim 4 , further comprising assigning the first tuner to tune the particular channel if the second tuner is not available for tuning.
6. A method as recited in claim 4 , further comprising assigning a third tuner to tune the particular channel if the first tuner and the second tuner are not available to tune the particular channel.
7. A method as recited in claim 4 , wherein determining whether a second tuner is available for tuning includes a first tuner querying the second tuner.
8. A method comprising:
receiving a request to record a program on a first channel;
assigning a first tuner to tune the first channel;
receiving a request to tune a second channel;
determining whether the second channel is already being tuned;
determining whether a second tuner is available for tuning;
assigning the first tuner to tune the second channel if the second channel is not already being tuned and the second tuner is not available for tuning; and
assigning the second tuner to tune the second channel if the second channel is not already being tuned and the second tuner is available for tuning.
9. A method as recited in claim 8 , further comprising switching to the tuner assigned to the second channel if the second channel is already being tuned.
10. A method as recited in claim 8 , further comprising assigning a third tuner to tune the first channel if the first tuner is not available to tune the first channel.
11. A method as recited in claim 8 , wherein determining whether a second tuner is available for tuning includes querying the second tuner to determine the status of the second tuner.
12. A method comprising:
receiving a request to record a program on a first channel;
assigning a first tuner to tune the first channel;
receiving a request to tune a second channel;
assigning a second tuner to tune the second channel if the second tuner is available for tuning;
receiving a request to tune the first channel;
switching to the first tuner; and
displaying an indicator that the user is now watching a recorded program.
13. A method as recited in claim 12 , wherein the recorded program data from the first channel is associated with the first tuner.
14. A method as recited in claim 12 , further comprising changing the status of the second tuner to an available state.
15. A method as recited in claim 12 , further comprising assigning the second tuner to tune the first channel if the first tuner is not available to tune the first channel.
16. A method as recited in claim 15 , wherein the recorded program data associated with the first tuner is modified to be associated with the second tuner if the first tuner is not available to tune the first channel.
17. A method as recited in claim 15 , wherein a new set of recorded program data is generated and associated with the second tuner.
18. A method as recited in claim 12 , wherein the method is performed by a set top box.
19. A method as recited in claim 12 , wherein switching to the first tuner includes displaying the program content currently being tuned by the first tuner.
20. A method as recited in claim 12 , wherein switching to the first tuner includes displaying previously recorded program content if the first tuner has been recording the tuned content.
21. One or more computer-readable media having stored thereon a computer program that, when executed by one or more processors, causes the one or more processors to:
receive a request to tune a first channel;
assign a first tuner to tune the first channel;
receive a request to tune a second channel;
determine whether a second tuner is available for tuning;
assign the first tuner to tune the second channel if the second tuner is not available for tuning; and
assign the second tuner to tune the second channel if the second tuner is available for tuning.
22. One or more computer-readable media as recited in claim 21 , wherein the second tuner is queried for a status of the second tuner to determine whether the second tuner is available for tuning.
23. One or more computer-readable media as recited in claim 21 , further causing the one or more processors to assign a third tuner to tune the second channel if the first tuner and the second tuner are not available to tune the second channel.
24. One or more computer-readable media as recited in claim 21 , further causing the one or more processors to display an indicator if the second channel is being recorded.
