Method and apparatus for store and replay functions in a digital radio broadcasting receiver

1. A method for receiving and processing a digital radio broadcasting signal, the method comprising:

using a single tuner to receive an in-band on-channel digital radio broadcasting signal comprised of a plurality of carriers in a single broadcast radio channel, with the carriers being modulated to concurrently transmit two or more different programs, each of the programs including encoded content in a first format;

processing the encoded content of a first one of the programs to convert the encoded content into a second format;

storing the encoded content of the first one of the programs in the second format;

decoding the encoded content of a second one of the programs to recover decoded content; and

using the decoded content of the second one of the programs to produce an output signal.

2. The method of claim 1 , wherein the encoded content in the first format comprises:

encoded, encapsulated packets pursuant to a logical protocol stack.

3. The method of claim 2 , wherein the encoded, encapsulated packets are transcoded into the second format.

4. The method of claim 2 , wherein the encoded, encapsulated packets are decoded and re-encoded into the second format.

5. The method of claim 1 , wherein the encoded content in the second format comprises:

an MP3 format.

6. The method of claim 1 , wherein the stored encoded content in the second format represents a plurality of programs, or portions of programs.

7. The method of claim 6 , wherein the stored encoded content corresponding to any one of the stored programs can be selected for playback at a time.

8. The method of claim 1 , wherein the programs comprise a main program and one or more supplemental programs.

9. A receiver for receiving and processing a digital radio broadcasting signal, the receiver comprising:

a single tuner to receive an in-band on-channel digital radio broadcasting signal comprised of a plurality of carriers in a single broadcast radio channel, with the carriers being modulated to concurrently transmit two or more different programs, each of the programs including encoded content in a first format;

a processor for processing the encoded content of a first one of the programs to convert the encoded content into a second format; and

a memory for storing the encoded content of the first one of the programs in a second format;

wherein the processor decodes the encoded content of a second one of the programs to recover decoded content, uses the decoded content of the second one of the programs to produce an output signal.

10. The receiver of claim 9 , wherein the processor processes the digital radio broadcasting signal through a protocol stack to extract the encoded content in the first format.

11. The receiver of claim 9 , wherein the encoded content in the first format comprises:

encoded, encapsulated packets pursuant to a logical protocol stack.

12. The receiver of claim 11 , wherein the processor transcodes the encoded, encapsulated packets into the second format.

13. The receiver of claim 11 , wherein the processor decodes the encoded, encapsulated packets and re-encodes the encoded, encapsulated packets into the second format.

14. The receiver of claim 9 , wherein the encoded content in the second format comprises:

an MP3 format.

15. The receiver of claim 9 , wherein the stored encoded content in the second format represents a plurality of programs, or portions of programs.

16. The receiver of claim 15 , wherein the stored encoded content corresponding to any one of the stored programs can be selected for playback at a time.

17. The receiver of claim 9 , wherein the encoded content represents a main program and one or more supplemental programs.
