Abstract

Systems and methods are provided for managing a time-shift buffer (TSB) that is used for buffering video presentations. One such method includes receiving user input identifying a storage capacity for the TSB and modifying a storage capacity of the TSB such that it is at least substantially equal to the storage capacity identified by the user input.

Claims (41)

1. A method for providing access to buffered data, the method comprising:

receiving user input specifying whether access is to be provided after a future change in a displayed television channel to a buffered video presentation that is buffered before the future change in the displayed television channel;

providing the access responsive to the user input specifying that the access is to be provided; and

preventing the access responsive to the user input specifying that the access is not to be provided.

2. The method of claim 1 , wherein the access is provided via a rewind operation.

3. The method of claim 1 , wherein the access is provided via a user interface screen containing a list of buffered video presentations.

4. The method of claim 1 , wherein the buffered video presentation is buffered in a time-shift buffer (TSB).

5. The method of claim 4 , wherein the TSB corresponds to a portion of a hard disk.

6. The method of claim 1 , wherein the buffered video presentation corresponds to a video stream that is received via a subscriber television network.

7. The method of claim 1 , wherein the buffered video presentation corresponds to a video stream that is received from a local device.

8. The method of claim 1 , wherein the user input identifies an option that is provided via a user interface screen.

9. The method of claim 1 , wherein the access is provided only if the displayed television channel had been designated as a favorite television channel.

10. The method of claim 1 , wherein the access is provided only if the buffered video presentation corresponds to a video presentation that had been designated as a favorite video presentation.

11. The method of claim 1 , wherein the user input is provided via a certain remote control key.

12. The method of claim 11 , wherein the user input is received within a short time interval prior to receiving a request for the change in the displayed television channel.

13. The method of claim 11 , wherein operation of the certain remote control key may be enabled in response to the selection of a certain option via a user interface screen.

14. A digital home communication terminal (DHCT) that is configured to receive user input specifying whether access is to be provided after a future change in a displayed television channel to a buffered video presentation that is buffered before the future change in the displayed television channel, the DHCT comprising:

a time-shift buffer (TSB) for buffering the buffered video presentation; and

a processor that is programmed to:

provide the access to the buffered video presentation responsive to the user input specifying that the access is to be provided; and

prevent the access to the buffered video presentation responsive to the user input specifying that the access is not to be provided.

15. The DHCT of claim 14 , wherein the access is provided via a rewind operation.

16. The DHCT of claim 14 , wherein the access is provided via a user interface screen containing a list of buffered video presentations.

17. The DHCT of claim 14 , wherein the TSB corresponds to a portion of a hard disk.

18. The DHCT of claim 14 , wherein the buffered video presentation corresponds to a video stream that is received via a subscriber television network.

19. The DHCT of claim 14 , wherein the buffered video presentation corresponds to a video stream that is received from a local device.

20. The DHCT of claim 14 , wherein the user input identifies an option that is provided via a user interface screen.

21. The DHCT of claim 14 , wherein the access is provided only if the displayed television channel had been designated as a favorite television channel.

22. The DHCT of claim 14 , wherein the access is provided only if the buffered video presentation corresponds to a video presentation that had been designated as a favorite video presentation.

23. The DHCT of claim 14 , wherein the user input is provided via a certain remote control key.

24. The DHCT of claim 23 , wherein the user input is received within a short time interval prior to receiving a request for the change in the displayed television channel.

25. The DHCT of claim 23 , wherein operation of the certain remote control key may be enabled in response to the selection of a certain option via a user interface screen.

26. A method for providing access to buffered data, the method comprising:

receiving user input specifying whether access is to be provided after a future change in a displayed television channel to a buffered video presentation that is buffered before the future change in the displayed television channel;

providing the access responsive to the user input specifying that the access is to be provided;

preventing the access responsive to the user input specifying that the access is not to be provided;

wherein the access is provided via a rewind operation;

wherein the buffered video presentation is buffered in a time-shift buffer (TSB);

wherein the TSB corresponds to a portion of a hard disk;

wherein the buffered video presentation corresponds to a video stream that is received via a subscriber television network; and

wherein the user input identifies an option that is provided via a user interface screen.
