Abstract

A method and system are provided in which one DVR device is able to coordinate scheduling of selected TV shows with other DVRs in an interconnected or network environment which includes additional remote recording resources. If one DVR is unable to perform the recording of a selected TV show, other interconnected DVR devices are accessed to record one or more portions of the selected TV program. When a user desires a playback of the recording, the recorded program is played-back from the various networked multiple storage resources, each of which may contain one or more portions of the recorded program.

Claims

1. A method for enabling storage of a selected video program scheduled to be presented at a first display station, said first display station including a first display device and a first control unit, said first control unit including a first storage unit, said first control unit being selectively operable for controlling recording of said selected video program, said method comprising:

determining that storage space required to store said selected video program exceeds storage space available within said first storage unit;

accessing storage units at additional control units until a cumulative total of storage space available at said additional control units is sufficient to store said selected video program; and

storing different portions of said selected video program at different ones of said additional storage units until all of said selected video program has been stored.

2. The method as set forth in claim 1 wherein said additional control units are coupled to said first control unit over a network coupling.

3. The method as set forth in claim 2 wherein each of said additional control units further includes a user control device selectively operable for enabling a user to provide input to said additional control units.

4. The method as set forth in claim 3 and further including:

enabling a user to playback said stored selected video program at a display device associated with any one of said additional control units.

5. The method as set forth in claim 4 wherein said playback of said stored selected video program is accomplished by:

sequentially playing back said different portions of said selected video program from said corresponding different ones of said additional storage units.

6. The method as set forth in claim 1 and further including:

enabling a playback of said selected video program, said playback being accomplished by sequentially playing back said different portions of said selected video program from said corresponding different ones of said additional storage units.

7. A programmed medium, said programmed medium being selectively accessible by a computer system to provide program signals, said program signals being operable for enabling storage of a selected video program scheduled to be presented at a first display station, said first display station including a first display device and a first control unit, said first control unit including a first storage unit, said first control unit being selectively operable for controlling recording of said selected video program, said program signals being further operable for:

determining that storage space required to store said selected video program exceeds storage space available within said first storage unit;

accessing storage units at additional control units until a cumulative total of storage space available at said additional control units is sufficient to store said selected video program; and

storing different portions of said selected video program at different ones of said additional storage units until all of said selected video program has been stored.

8. The medium as set forth in claim 7 wherein said additional control units are coupled to said first control unit over a network coupling.

9. The medium as set forth in claim 8 wherein each of said additional control units further includes a user control device selectively operable for enabling a user to provide input to said additional control units.

10. The medium as set forth in claim 9 wherein said program signals are further effective for enabling a user to playback said stored selected video program at a display device associated with any one of said additional control units.

11. The medium as set forth in claim 10 wherein said program signals are further effective for enabling a playback said stored selected video program by sequentially playing back said different portions of said selected video program from said corresponding different ones of said additional storage units.

12. The medium as set forth in claim 7 wherein said program signals are further effective for enabling a playback of said selected video program, said playback being accomplished by sequentially playing back said different portions of said selected video program from said corresponding different ones of said additional storage units.

13. A system for enabling storage of a selected video program scheduled to be presented at a first display station, said system comprising:

a first display station including a first display device and a first control unit, said first control unit including a first storage unit, said first control unit being selectively operable for controlling recording of said selected video program;

means for determining that storage space required to store said selected video program exceeds storage space available within said first storage unit;

means for accessing storage units at additional control units until a cumulative total of storage space available at said additional control units is sufficient to store said selected video program; and

means for storing different portions of said selected video program at different ones of said additional storage units until all of said selected video program has been stored.

14. The system as set forth in claim 13 wherein said additional control units are coupled to said first control unit over a network coupling.

15. The system as set forth in claim 14 wherein each of said additional control units further includes a user control device selectively operable for enabling a user to provide input to said additional control units.

16. The system as set forth in claim 15 and further including means for enabling a user to playback said stored selected video program at a display device associated with any one of said additional control units.

17. The system as set forth in claim 16 and further including means for sequentially playing back said different portions of said selected video program from said corresponding different ones of said additional storage units.

18. The system as set forth in claim 13 and further including means for enabling a playback of said selected video program, said playback being accomplished by sequentially playing back said different portions of said selected video program from said corresponding different ones of said additional storage units.
