Abstract

A system receives a broadcast data stream that is encoded using any encoding format. The received broadcast data stream is demultiplexed and stored on a storage device. In response to a command to play back the stored broadcast data stream, the stored data stream is retrieved and rendered in a manner that corresponds to the play back command. Multiple systems may retrieve the stored broadcast data stream simultaneously.

Claims

1. A method comprising:

receiving a broadcast data stream, wherein the broadcast data stream is encoded using any encoding format;

demultiplexing the received broadcast data stream;

storing the received broadcast data stream on a storage device; and

time shifting the broadcast data stream.

2. A method as recited in claim 1 wherein the broadcast data stream is a digital data stream.

3. A method as recited in claim 1 wherein the broadcast data stream may utilize any data format.

4. A method as recited in claim 1 wherein storing the received broadcast data stream on a storage device includes writing the broadcast data stream to an application programming interface.

5. A method as recited in claim 1 further comprising retrieving the broadcast data stream from the storage device.

6. A method as recited in claim 1 further comprising multiple systems retrieving the broadcast data stream simultaneously.

7. A method as recited in claim 1 further comprising retrieving different portions of the broadcast data stream simultaneously.

8. A method as recited in claim 1 wherein the received broadcast stream is stored on the storage device using a plurality of temporary files.

9. A method as recited in claim 1 wherein the received broadcast stream is stored on the storage device using a single temporary file.

10. A method as recited in claim 1 wherein the received broadcast at least one permanent file.

11. One or more computer-readable memories containing a computer program that is executable by a processor to perform the method recited in claim 1.

13. A method as recited in claim 12 further comprising:

receiving a command to pause play back of the digital data stream; and

halting rendering of the components of the digital data stream in response to the pause command.

14. A method as recited in claim 12 wherein the play back command is a play command.

15. A method as recited in claim 12 wherein the play back command is a rewind command.

16. A method as recited in claim 12 wherein the play back command is a fast forward command.

17. A method as recited in claim 12 wherein the play back command is a seek command.

18. A method as recited in claim 12 wherein the play back command is a slow motion play command.

19. A method as recited in claim 12 wherein the play back command is a skip forward command.

20. A method as recited in claim 12 wherein the play back command is a skip backward command.

21. A method as recited in claim 12 wherein storing the components of the digital data stream on a storage device includes writing the components of the digital data stream to an application programming interface.

22. A method as recited in claim 12 wherein the storage device is a hard disk drive.

23. A method as recited in claim 12 wherein the storage device is a hard disk drive and components of the digital data stream are stored in at least one temporary file or at least one permanent file on the hard disk drive.

24. A method as recited in claim 12 wherein the digital data stream can be encoded using any encoding format.

25. A method as recited in claim 12 wherein the digital data stream may utilize any data format.

26. A method as recited in claim 12 wherein multiple devices retrieve the stored components of the digital data stream simultaneously.

27. A method as recited in claim 12 wherein retrieving the stored components of the digital data stream includes:

a first device retrieving data associated with a first data stream stored on the storage device; and

a second device simultaneously retrieving data associated with a second data stream stored on the storage device.

28. A method as recited in claim 12 wherein retrieving the stored components of the digital data stream includes:

a first device retrieving data from a first location in the digital data stream; and

a second device simultaneously retrieving data from a second location in the digital data stream.

29. A method as recited in claim 12 wherein separating components of the digital data stream includes demultiplexing video data and audio data from the digital data stream.

30. A method as recited in claim 12 wherein separating components of the digital data stream includes demultiplexing Internet Protocol data from the digital data stream.

31. One or more computer-readable memories containing a computer program that is executable by a processor to perform the method recited in claim 12.

12. A method comprising:

receiving a digital data stream;

separating components of the digital data stream;

storing the components of the digital data stream on a storage device;

receiving a command to play back the digital data stream;

retrieving at least one of the stored components of the digital data stream from the storage device; and

rendering the components of the digital data stream in a manner that corresponds to the received play back command.

32. A method comprising:

receiving a broadcast data stream;

separating components of the broadcast data stream;

storing the components of the broadcast data stream on a storage device;

retrieving the components of the broadcast data stream from the storage device;

rendering the components of the broadcast data stream; and

receiving a request to pause rendering of the broadcast data stream, in response to the pause request;

halting rendering of the broadcast data stream;

continuing to store the components of the broadcast data stream on the storage device.

33. A method as recited in claim 32 wherein the broadcast data stream is a television broadcast.

34. A method as recited in claim 32 wherein the broadcast data stream is a digital data stream.

35. A method as recited in claim 32 further comprising:

receiving a request to resume rendering of the broadcast data stream; and

rendering the broadcast data stream based on the request to resume rendering of the broadcast data stream.

36. One or more computer-readable memories containing a computer program that is executable by a processor to perform the method recited in claim 32.

38. One or more computer-readable media as recited in claim 37 wherein rendering the components of the broadcast stream includes rendering the components of the broadcast stream in a manner that corresponds to the received play back request.

39. One or more computer-readable media as recited in claim 37 wherein rendering the components of the broadcast stream includes rendering multiple copies of the broadcast stream simultaneously.

40. One or more computer-readable media as recited in claim 37 wherein the broadcast data stream is a television broadcast.
