Method and apparatus for store and replay functions in a digital radio broadcasting receiver
View Patent ↗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.
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.
