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. A first media player/recorder, comprising:

a wireless transceiver configured to receive, from a second media player/recorder, i) encodcd media data and ii) a request including an identifier of a sought encoded media selection;

a storage device configured to store i) the encoded media data and ii) a list of identifiers of shared encoded media selections stored on the storage device, wherein the wireless transceiver is further configured to transmit at least one of the identifiers of the shared encoded media selections prior to the request being received by the first media player/recorder via the wireless transceiver; and

a processor configured to i) compare the identifier of the sought encoded media selection with the list and ii) in response to the identifier of the sought encoded media selection matching one of the identifiers of the shared encoded media selections, cause the wireless transceiver to transmit, from the first media player/recorder to the second media player/recorder, encoded media data corresponding to the matched one of the identifiers.

2. The first media player/recorder of claim 1, wherein the processor retrieves the encoded media data from the storage device and decodes the encoded media data.

3. The first media player/recorder of claim 1, further comprising an output circuit to output decoded media data from the processor.

4. The first media player/recorder of claim 2, wherein the processor comprises a single integrated circuit.

5. The first media player/recorder of claim 1, wherein the storage device comprises non-volatile semiconductor memory.

6. The first media player/recorder of claim 1, wherein the storage device comprises a hard disk drive.

7. A method of operating a first media player/recorder, the method comprising:

receiving, from a second media player/recorder, i) encoded media data and ii) a request including an identifier of a sought encoded media selection;

storing i) the encoded media data and ii) a list of identifiers of shared encoded media selections;

comparing the identifier of the sought encoded media selection with the list;

in response to the identifier of the sought encoded media selection matching one of the identifiers of the shared encoded media selections, causing a wireless transceiver to transmit, from the first media player/recorder to the second media player/recorder, encoded media data corresponding to the matched one of the identifiers; and

transmitting at least one of the identifiers of the shared encoded media selections to the second media player/recorder prior to the request being received from the second media player/recorder.

8. The method of claim 7, further comprising:

retrieving the encoded media data from a storage device; and

decoding the encoded media data.

9. The method of claim 7, further comprising outputting decoded media data from a processor.
