Abstract

A method for receiving and processing a digital radio broadcasting signal includes: receiving a digital radio broadcasting signal comprised of two or more multicast contents, playing a first one of the multicast contents, and concurrently storing a second one of the multicast contents. 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;

processing the radio broadcasting signal through one or more layers of a protocol stack to produce encoded content for each of the programs;

processing the encoded content for a first one of the programs to produce an audio output; and

concurrently storing the encoded content for a second one of the programs.

2. The method of claim 1, wherein the programs comprise:

a main program and one or more supplemental programs.

3. The method of claim 1, further comprising:

scheduling recording of a particular one of the programs.

4. The method of claim 1, further comprising:

selecting one of the programs for recording based on genre or other program-related information.

5. The method of claim 1, further comprising:

recording encoded content for multiple programs at once.

6. The method of claim 1, further comprising:

listening to one program while recording one or more different programs.

7. The method of claim 1, further comprising:

deleting files individually, collectively based on certain criteria, or using an auto-erase function.

8. The method of claim 1, wherein the encoded content comprises protocol data units.

9. The method of claim 1, wherein the encoded content comprises encapsulated packets.

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

a single tuner for receiving 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;

a processor for processing the radio broadcasting signal through one or more layers of a protocol stack to produce encoded content for each of the programs, and for processing the encoded content for a first one of the programs to produce an audio output; and

a memory for concurrently storing the encoded content for a second one of the programs.

11. The receiver of claim 10, wherein the programs comprise:

a main program and one or more supplemental programs.

12. 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;

processing the radio broadcasting signal through one or more layers of a protocol stack to produce encoded content for each of the programs; and

concurrently storing the encoded content for at least two of the programs.

13. The method of claim 12, wherein the programs comprise:

a main program and one or more supplemental programs.

14. The method of claim 12, further comprising the step of:

processing previously stored encoded content to produce an audio output while the encoded content for the at least two of the programs are being stored.

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

a single tuner for receiving 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;

a processor for processing the radio broadcasting signal through one or more layers of a protocol stack to produce encoded content for each of the programs; and

a memory for concurrently storing the encoded content for two or more of the programs.

16. The receiver of claim 15, wherein the programs comprise:

a main program and one or more supplemental programs.
