Abstract

An apparatus, method and software program product for rapid archiving and restoring of a video store. The method includes receiving and recording video signals representing the video data more than one time responsive to a first command; and terminating the recording of the video signals responsive to a second command. The recoding of the video signals is performed at a video rate. The method further includes receiving video signals from the video recoding device playing back the stored plurality of instances of the video data; recording the received video signals to a memory responsive to a command; and terminating the recording process when the memory is filled, wherein the recorded video signals includes at least one instance of the video.

Claims

1. A method for recording video data comprising:

receiving video signals representing a first video data responsive to a first command;

recording a portion of the received video signals; and

terminating the recording process responsive to a second command, wherein the recorded video signals represent more than one instance of the first video data.

2. The method of claim 1, wherein the recording step further comprises:

digitizing the portion of the received video signals.

3. The method of claim 2, wherein the recording step further comprises:

encoding the digitized video signals.

4. The method of claim 1, wherein the video signals are generated by repeatedly playing the first video data from a video store a predetermined number of times.

5. The method of claim 4, further comprising the step of receiving the second command after the predetermined number of times has been played.

6. The method of claim 4, wherein the video store plays the first video data at a video rate.

7. The method of claim 1, wherein the first video data includes a frame identifying beginning of the first video data.

8. A computer program product including a computer-readable medium comprising software instructions operable to enable a computer to perform a method for archiving first video data from a video store comprising:

receiving video signals representing the first video data responsive to a first command;

recording a portion of the received video signals; and

terminating the recording process responsive to a second command wherein the recorded video signals represent more than one instance of the first video data.

9. The computer program product of claim 8, wherein the recording step further comprises:

digitizing the portion of the received video signals.

10. The computer program product of claim 9, wherein the recording step further comprises:

encoding the digitized video signals.

11. The computer program product of claim 8, wherein the video signals are generated by repeatedly playing the first video data from the video store a predetermined number of times.

12. The computer program product of claim 11, further comprising the step of receiving the second command after the predetermined number of times has been played.

13. The computer program product of claim 8, wherein the video store plays the first video data at a video rate.

14. The computer program product of claim 8, wherein the first video data includes a frame identifying beginning of the first video data.

15. A method for restoring first video data from a video recoding device storing second video data representing more than one instance of the first video data, comprising:

receiving video signals from the video recoding device playing back the second video data;

recording a portion of the received video signals to a memory responsive to a command; and

terminating the recording process when the memory is filled, wherein the recorded video signals represents at least one instance of the first video data.

16. The method of claim 15, further comprising:

setting a video store into the archival restore loop mode; and

waiting for the memory to be filled.

17. The method of claim 15, wherein the first video data includes a frame identifying beginning of the first video data.

18. The method of claim 17, further comprising:

receiving a command to resynchronize metadata with the recorded video signals, the metadata including address information of the identifying frame in the memory; and

resynchronizing the metadata with the recorded video signals by identifying a frame in the recorded video signals representing the identifying frame of the first video data.

19. The method of claim 18, wherein the step of resynchronizing of the metadata further comprising:

determining an address of the frame representing the identifying (ID) frame; and

correcting the address information in the metadata using the determined address.

20. The method of claim 15, wherein the recording step further comprises:

digitizing the portion of the received video signals;

encoding the digitized video signals; and

recording the encoded video signals.

22. The computer program product of claim 19, further comprising:

setting the video store into the archival restore loop mode; and

waiting for the memory to be filled.

23. The computer program product of claim 20, wherein the first video data includes a frame identifying beginning of the first video data.

21. A computer program product including a computer-readable medium comprising software instructions operable to enable a computer to perform a method restoring first video data to a video store from a video recoding device storing a second video data representing more than one instance of the first video data, comprising:

receiving video signals from the video recoding device playing back the second video data;

recording a portion of the received video signals to a memory responsive to a command; and

terminating the recording process when the memory is filled, wherein the recorded video signals represents at least one instance of the first video data.

24. The computer program product of claim 21, further comprising:

receiving a command to resynchronize metadata with the recorded archival video newly recorded on the video store, the metadata including address information of the identifying frame in the memory; and

resynchronizing the metadata with the recorded video signals by identifying a frame in the recorded video signals representing the identifying frame of the first.

25. The computer program product of claim 24, wherein the step of resynchronizing of the metadata further comprising:

determining an address of the frame representing the identifying (ID) frame; and

correcting the address information in the metadata using the determined address.

26. The computer program product of claim 21, wherein the recording step further comprises:

digitizing the portion of the received video signals;

encoding the digitized video signals; and

recording the encoded video signals.

27. A method for recording video data comprising:

receiving, by a video store, a first command for repeatedly playing back the first video data for a number of times; and

playing back, by the video store, the first video data for the number of times, wherein a portion of the played first video data is recorded by a video recording device and the recorded played first video data represents more than one instance of the first video data.

28. A method for restoring first video data from a video recoding device storing second video data representing more than one instance of the first video data, comprising:

transmitting video signals from the video recoding device playing back the second video data, wherein the video signals are received by a video store and a portion of said received video signals is recorded by the video store in a memory; and

terminating the playing back process responsive to a signal generated when the memory has been filled and the recorded video signals represent at least one instance of the first video data.
