Abstract

A method for receiving and processing a digital radio broadcasting signal includes: receiving a digital radio broadcasting signal including encoded content in a first format; processing the encoded content to convert the encoded content into a second format; storing the encoded content in a second format; and decoding the stored encoded content to recover decoded content. A receiver that implements the method is also provided.

Claims

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.
