Abstract

A multimedia signal processing system allows a user to store selected programs while simultaneously watching or reviewing another. The system includes an input section and an output section. Across all configurations, the output section remains substantially the same, while the input section varies according to the signal type and the source. The system receives a digital stream and simultaneously processes the digital stream for display and stores the digital stream on at least one storage device. The system further simultaneously processes a previously recorded digital stream for display while processing the digital stream for display.

wherein the decoder decodes the digital stream for output to a display device.

5. The method of claim 1, wherein the digital stream is an MPEG stream.

6. The method of claim 1, wherein the simultaneously step further comprises:

processing a previously recorded digital stream stored on the at least one storage device for display simultaneous with the processing of the digital stream for display.

7. The method of claim 6, wherein the processing step processes the previously recorded digital stream using identifying information associated with the previously recorded digital stream.

8. The method of claim 1, wherein the at least one storage device contains a plurality of previously recorded digital streams.

9. A method for the simultaneous storage and retrieval of multimedia information, comprising:

processing a digital stream on a multimedia recording device;

simultaneously sending the digital stream to a decoder and storing the digital stream on at least one storage device; and

wherein the decoder decodes the digital stream for display.

10. The method of claim 9, wherein the processing step receives the digital stream from an input device.

11. The method of claim 10, wherein the input device receives digital signals.

12. The method of claim 9, wherein the digital stream is an MPEG stream.

13. The method of claim 9, wherein the simultaneously step further comprises:

sending a previously recorded digital stream stored on the at least one storage device to a second decoder simultaneous with the sending the digital stream to the decoder.

14. The method of claim 13, wherein the second decoder decodes the previously recorded digital stream for display.

15. The method of claim 9, wherein the at least one storage device contains a plurality of previously recorded digital streams.

16. An apparatus for the simultaneous storage and retrieval of multimedia information, comprising:

a receiver subsystem on a multimedia recording device that receives a digital stream; and

at least one storage device;

a processing subsystem that simultaneously processes the digital stream for display and stores the digital stream on the at least one storage device.

17. The apparatus of claim 16, wherein the receiving subsystem receives the digital stream from an input subsystem.

18. The apparatus of claim 17, wherein the input subsystem receives digital signals.
