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

1. A computer-implemented method for providing access to buffered data in a time-shift buffer, the method comprising:

receiving first data corresponding to successive portions of a first video signal, the first video signal corresponding to a first television program;

processing the first data for presentation at a display device;

while the first data is presented at the display device, receiving an input corresponding to a request for third data corresponding to successive portions of a second video signal, the second video signal corresponding to a second television program;

accessing the third data;

processing the third data for presentation at the display device; and

buffering second data corresponding to successive portions of the first video signal while the third data is presented based on a defined presentation time of the first television program, the first video signal corresponding to the first television program.

2. The method of claim 1, further comprising enabling access by a user to the buffered second data responsive to a user request.

3. The method of claim 2, further comprising presenting a configuration interface that enables the access.

4. The method of claim 1, wherein the second data is buffered or accessible only if the first television program is presented for display for the defined presentation time.

5. The method of claim 1, wherein the defined threshold is user defined.

6. A computer-implemented method for providing access to buffered data in a time-shift buffer, the method comprising:

receiving first data corresponding to successive portions of a first video signal, the first video signal corresponding to a first television program;

processing the first data for display;

buffering the first data;

receiving first user input, the first user input corresponding to whether access to the buffered first television program is to be enabled or disabled;

receiving a second user input requesting access to second data corresponding to successive portions of a second video signal, the second video signal corresponding to a second television program;

responsive to the second user input, receiving the processing the second data for display;

receiving a third user input corresponding to a request for access to the buffered first data; and

accessing the buffered first data responsive to the first user input corresponding to access, otherwise denying access to the first data.

7. The method of claim 6, wherein denying access comprises rendering the buffered first data inaccessible.

8. The method of claim 7, wherein the buffered data is deleted.

9. The method of claim 7, wherein the buffered data is designated through a corresponding management file as inaccessible.

10. The method of claim 6, further comprising providing a user interface to enable or disable access.

11. The method of claim 10, wherein the user interface comprises a remote control device in conjunction with a user interface screen.

12. A computer-implemented method of managing a time-shift buffer, comprising:

providing a first user interface that provides a list of buffered video presentations;

enabling a user to order the list according to buffering activity of each of the buffered video presentations;

receiving user input corresponding to ordering the list according to buffering activity; and

responsive to receiving the user input, ordering the list based on the buffering activity of each buffered video presentation.

13. The method of claim 12, wherein the buffering activity comprises buffered length of each of the buffered video presentations.

14. The method of claim 13, further comprising providing a second user interface that provides the ordered list of buffered video presentations.

15. The method of claim 14, wherein ordering comprises sorting based on play-time duration of each of the buffered video presentations.

16. The method of claim 15, wherein ordering comprises presenting a first title of the buffered video presentations having a first play time duration above a second title having a second play-time duration different than the first play time duration.

17. The method of claim 12, wherein the buffering activity comprises start time of each of the buffered video presentations.

18. The method of claim 17, further comprising providing a third user interface that provides the ordered list of buffered video presentations.

19. The method of claim 18, wherein ordering comprises sorting based on broadcast time of each of the buffered video presentations.

20. The method of claim 18, wherein ordering comprises presenting a first title of the buffered video presentations having a first start time above a second title having a second start time different than the first start time.
