Abstract

A method for managing a plurality of video data stored on a storage device. The method including the steps of: determining whether sufficient storage space remains on the storage device to store a desired video content; if sufficient storage space does not exist on the storage device to store the desired video content, determining whether any video content of the plurality of video data stored on the storage device has been partially viewed; and if video content stored on the storage device has been partially viewed, deleting the partially viewed video content to make room for storage of the desired video content on the storage device.

Claims

1. A method for managing a plurality of video data stored on a storage device, the method comprising:

(a) determining whether sufficient storage space remains on the storage device to store a desired video content;

(b) if sufficient storage space does not exist on the storage device to store the desired video content, determining whether any video content of the plurality of video data stored on the storage device has been partially viewed; and

(c) if video content stored on the storage device has been partially viewed, deleting the partially viewed video content to make room for storage of the desired video content on the storage device.

2. The method of claim 1, wherein if it is determined that no video content stored on the storage device has been partially viewed, the method further comprises deleting video content of the plurality of video data which was first stored on the storage device until there is sufficient space on the storage device to store the desired video content.

3. The method of claim 1, further comprising storing the desired video content after deleting of the partially viewed video content.

4. The method of claim 1, further comprising repeating steps (b) and (c) until there is sufficient space on the storage device to store the desired video content.

5. The method of claim 1, further comprising tagging video content which has been partially viewed with an indication identifying the video content as partially viewed.

6. The method of claim 5, wherein the determining of whether any video content of the plurality of video data stored on the storage device has been partially viewed comprises searching the plurality of video data for the tagged video content.

7. The method of claim 5, wherein the partially viewed video content is further date tagged indicating a date on which the video content was partially viewed, wherein the deleting comprises:

ordering the partially viewed video content in sequential order according to their corresponding date tag; and

deleting the partially viewed video content having the oldest date tag.

8. The method of claim 7, further comprising repeating the deleting of the partially viewed particular video content having the oldest date tag until there is sufficient space on the storage device to store the desired video content.

9. The method of claim 5, wherein the partially viewed video content is further recommender tagged indicating a likelihood that a viewer would enjoy viewing the partially viewed video content, wherein the deleting comprises:

determining whether the partially viewed video content has a positive recommendation from the recommender tag; and

deleting the partially viewed video content having a recommender tag indicating the viewer would be unlikely to enjoy viewing thereof.

10. The method of claim 9, wherein the recommender tag indicates a recommender score and wherein the determining of whether the partially viewed video content has a positive recommendation comprises determining whether the recommender score is greater than a predetermined threshold score.

11. The method of claim 5, further comprising prompting a viewer after termination of the partially viewed video content if the partially viewed video content should be tagged not to be deleted.

12. The method of claim 11, wherein the deleting of the partially viewed video content to make room for storage of the desired video content on the storage device comprises:

determining whether the partially viewed video content has been tagged not to be deleted; and

deleting partially viewed video content to make room for storage of the desired video content on the storage device only if the partially viewed video content has not been tagged not to be deleted.

13. A personal video recorder comprising:

a storage device for storing video data, the video data comprising a plurality of video content; and

a processor for retrieving one of the plurality of video content from the storage device for viewing, determining whether the viewed video content is partially viewed, and tagging the viewed video content as being partially viewed.

14. The personal video recorder of claim 13, further comprising means for indicating storage of a desired video content, wherein the processor further determines whether there is sufficient storage space on the storage device to store the desired video content and if there is not enough storage space to store the desired video content, deletes the partially viewed video content.

15. The personal video recorder of claim 14, wherein the processor further tags the partially viewed video content with a tag indicating a date on which the video content was partially viewed, orders the partially viewed video content in sequential order according to their corresponding date tag, and if there is not enough storage space to store the desired video content, deletes the partially viewed video content having the oldest date tag.

16. The method of claim 14, wherein the processor further tags the partially viewed video content with a recommendation indicating a likelihood that a viewer would enjoy viewing the partially viewed video content, determines whether the partially viewed video content has a positive recommendation from the recommender tag, and deletes the partially viewed video content having a recommendation tag indicating the viewer would be unlikely to enjoy viewing thereof.

17. The personal video recorder of claim 14, wherein the processor further prompts a viewer after termination of the partially viewed video content if the partially viewed video content should be tagged not to be deleted and the personal video recorder further comprises means for indicating whether the partially viewed video content should be tagged not to be deleted.

18. The personal video recorder of claim 17, wherein the processor further determines whether the partially viewed video content has been tagged not to be deleted, and deletes partially viewed video content to make room for storage of the desired video content on the storage device only if the partially viewed video content has not been tagged not to be deleted.

19. A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for managing a plurality of video data stored on a storage device, the method comprising:

determining whether sufficient storage space remains on the storage device to store a desired video content;

if sufficient storage space does not exist on the storage device to store the desired video content, determining whether any video content of the plurality of video data stored on the storage device has been partially viewed; and

if video content stored on the storage device has been partially viewed, deleting the partially viewed video content to make room for storage of the desired video content on the storage device.

20. A computer program product embodied in a computer-readable medium for managing a plurality of video data stored on a storage device, the computer program product comprising:

computer readable program code means for determining whether sufficient storage space remains on the storage device to store a desired video content;

computer readable program code means for determining whether any video content of the plurality of video data stored on the storage device has been partially viewed if sufficient storage space does not exist on the storage device to store the desired video content; and

computer readable program code means for deleting the partially viewed video content to make room for storage of the desired video content on the storage device if video content stored on the storage device has been partially viewed.
