Abstract

A media player/recorder, and a method and computer program product for same comprises a wireless receiver to receive a signal representing encoded media data; a storage device to store the encoded media data; a processor comprising a storage controller to retrieve the encoded media data from the storage device, and a digital signal processor to decode the encoded media data retrieved by the storage controller; and an output circuit to output the decoded media data from the processor.

Claims

1. (canceled)

2. A media player/recorder comprising:

a wireless receiver that receives encoded media data and an identifier of an offered encoded media selection;

a storage device that stores the encoded media data and a list of identifiers of desired encoded media selections; and

a processor that compares the identifier of the offered encoded media selection to the list.

3. The media player/recorder of claim 2 wherein the processor stores encoded media data corresponding to the offered encoded media selection when the identifier matches at least one identifier in the list.

4. The media player/recorder of claim 2 wherein the processor retrieves and decodes the encoded media data from the storage device.

5. The media player/recorder of claim 4 further comprising an output circuit that outputs the decoded media data from the processor.

6. The media player/recorder of claim 4 wherein the encoded media data is compressed and the decoded media data is decompressed.

7. The media player/recorder of claim 4 wherein the processor comprises a single integrated circuit.

8. The media player/recorder of claim 2 further comprising a read channel that communicates with the processor and that writes data to and reads data from the storage device.

9. The media player/recorder of claim 4 further comprising memory to store the encoded media data retrieved by the processor.

10. The media player/recorder of claim 4 further comprising an input circuit to receive unencoded media data, wherein the processor encodes the unencoded media data and stores the encoded media data on the storage device.

11. The media player/recorder of claim 2 wherein the storage device comprises non-volatile semiconductor memory.

12. The media player/recorder of claim 2 wherein the storage device comprises a hard disk drive.

13. A media player/recorder comprising:

a wireless transceiver to receive encoded media data and a request including an identifier of a sought encoded media selection;

a storage device to store the encoded media data and a list of identifiers of shared encoded media selections stored on the storage device; and

a processor that compares the identifier of the sought encoded media selection with the list.

14. The media player/recorder of claim 13 wherein the processor causes the wireless transceiver to transmit encoded media data corresponding to a matched one of the shared encoded media selections when the identifier of the matched one matches the identifier of the sought encoded media selection.

15. The media player/recorder of claim 13 wherein the processor retrieves the encoded media data from the storage device and decodes the encoded media data.

16. The media player/recorder of claim 13 further comprising an output circuit to output the decoded media data from the processor.

17. The media player/recorder of claim 14 wherein the wireless transceiver transmits at least one of the identifiers of the shared encoded media selections before said request is received.

18. The media player/recorder of claim 15 wherein the processor comprises a single integrated circuit.

19. The media player/recorder of claim 13 wherein the storage device comprises non-volatile semiconductor memory.

20. The media player/recorder of claim 13 wherein the storage device comprises a hard disk drive.

21. A media player/recorder comprising:

a wireless receiver to receive encoded media data and an offered item of interest;

a storage device to store the encoded media data and a list of desired items of interest;

a processor that compares the offered item of interest to the list of desired items of interest and that selectively indicates a match when the offered item of interest corresponds to one of the desired items of interest; and

a display unit that communicates with the processor and that indicates the match.

22. The media player/recorder of claim 21 wherein the processor retrieves the encoded media data from the storage device and decodes the encoded media data retrieved by the storage controller.

23. The media player/recorder of claim 21 further comprising an output circuit to output the decoded media data from the processor.

24. The media player/recorder of claim 21 further comprising a directional antenna to determine a direction to a transmitter of the offered item of interest, wherein the display unit displays the direction.

25. The media player/recorder of claim 21 further comprising a wireless transmitter to transmit contact information to a remote transceiver associated with the offered item of interest.

26. The media player/recorder of claim 21 further comprising a wireless transmitter to transmit data representing a matched one of the desired items of interest.

27. The media player/recorder of claim 21 wherein the storage device comprises non-volatile semiconductor memory.

28. The media player/recorder of claim 21 wherein the storage device comprises a hard disk drive.
