Abstract

A method of operating a radio in a vehicle includes tuning the radio to a first radio source. Information identifying the first radio source is transmitted from the vehicle to a remote processor. The processor monitors broadcast content of the first radio source on a web site. The processor identifies a second radio source having broadcast content matching the broadcast content of the first radio source. Information identifying the second radio source is transmitted from the processor to the vehicle. When a quality of a broadcast signal from the first radio source received at the vehicle falls below a threshold quality level, tuning of the radio is switched from the first radio source to the second radio source.

Claims

1. A method of operating a radio in a vehicle, comprising the steps of:

using the radio to tune to a first radio source;

transmitting information identifying the first radio source from the vehicle to a processor disposed at a location that is remote from the vehicle;

monitoring by the processor broadcast content of the first radio source on a web site of the first radio source;

identifying by the processor a second radio source having broadcast content matching the broadcast content of the first radio source;

transmitting information identifying the second radio source from the processor to the vehicle;

detecting a quality of a broadcast signal from the first radio source received at the vehicle falling below a threshold quality level; and

responding to the detecting step by switching tuning of the radio from the first radio source to the second radio source.

2. The method of claim 1 comprising the further steps of:

transmitting geographical coordinates of the vehicle from the vehicle to the processor, the geographical coordinates being provided by a GPS; and

using the geographical coordinates at the processor to identifying the first radio source.

3. The method of claim 1 wherein the signal quality metric is dependent upon at least one of field strength, level of multipath, ultrasonic noise, and bit error rate.

4. The method of claim 1 wherein the information identifying the first radio source comprises:

service identification if the first radio source comprises digital audio broadcasting;

Main Program Service (MPS) and/or Supplemental Program Service (SPS) information if the first radio source comprises HD IBOC;

if the first radio source comprises an FM analog station, then a vehicle GPS location and at least one of call letters of the station and a broadcast frequency of the station; and

a program ID (PI) code if the first radio source comprises an RDS station.

5. The method of claim 1 wherein the step of using the processor to identify a second radio source having broadcast content matching the broadcast content of the first radio source includes monitoring broadcast content of the second radio source on a web site of the second radio source.

6. The method of claim 1 comprising the further steps of:

measuring a quality of a broadcast signal from the second radio source received at the vehicle;

transmitting information regarding the measured quality of the broadcast signal from the second radio source from the vehicle to the processor;

using the processor to record broadcast content of the second radio source from a web site of the second radio source, the broadcast content being recorded when the measured quality of the broadcast signal from the second radio source is above a threshold level; and

transmitting the recorded broadcast content of the second radio source from the processor to the vehicle.

7. The method of claim 6 wherein the broadcast content of the second radio source is recorded when the second radio source has been stored as a preset frequency and/or the radio has been tuned to the second radio source for more than a threshold amount of time.

8. A method of operating a radio in a vehicle, comprising the steps of:

using the radio to tune to a radio source;

transmitting information identifying the radio source from the vehicle to a processor disposed at a location that is remote from the vehicle;

measuring a quality of a broadcast signal from the radio source received at the vehicle;

transmitting information regarding the measured quality of the broadcast signal from the vehicle to the processor;

recording by the processor broadcast content of the radio source from a web site of the radio source, the broadcast content being recorded when the measured quality of the broadcast signal is above a threshold level; and

transmitting the recorded broadcast content of the radio source from the processor to the vehicle.

9. The method of claim 8 wherein the quality of the broadcast signal is dependent upon at least one of field strength, level of multipath, and ultrasonic noise.

10. The method of claim 8 wherein the broadcast content is recorded when the radio has been receiving the broadcast signal from the radio source for greater than a threshold amount of time.

11. The method of claim 8 wherein the broadcast content is recorded when the user has selected time shift for a configuration of the radio.

12. The method of claim 8 wherein the radio source comprises a first radio source, the method comprising the further step of automatically switching tuning of the radio from the first radio source to a second radio source having broadcast content matching the broadcast content of the first radio source, the switching being performed when the measured quality of the broadcast signal is below the threshold level.

13. The method of claim 12 comprising the further steps of:

using the processor to monitor broadcast content of the first radio source on a web site of the first radio source; and

using the processor to identify the second radio source as having broadcast content matching the broadcast content of the first radio source.

14. The method of claim 8 wherein the information identifying the radio source comprises:

service identification if the radio source comprises digital audio broadcasting;

Main Program Service (MPS) and/or Supplemental Program Service (SPS) information if the radio source comprises HD IBOC;

if the radio source comprises an FM analog station, then call letters of the station and/or a broadcast frequency of the station; and

a program ID (PI) code if the radio source comprises an RDS station.

15. A method of operating a radio within a vehicle, comprising the steps of:

using the radio to tune to a radio source;

transmitting information identifying the radio source from the vehicle to a processor disposed at a location that is remote from the vehicle;

measuring a quality of a broadcast signal from the radio source received at the vehicle;

transmitting information regarding the measured quality of the broadcast signal from the vehicle to the processor;

recording by the processor broadcast content of the radio source from a web site of the radio source, the broadcast content is recorded when the radio source has been stored as a preset frequency and/or the radio has been tuned to the radio source for more than a threshold amount of time; and

transmitting the recorded broadcast content of the radio source from the processor to the vehicle.

16. The method of claim 15 wherein the broadcast content is recorded when the measured quality of the broadcast signal is above a threshold level.

17. The method of claim 15 wherein the quality of the broadcast signal is dependent upon at least one of field strength, level of multipath, and ultrasonic noise.

18. The method of claim 15 wherein the broadcast content is recorded when time shift is currently selected as the configuration of the radio.

19. The method of claim 15 wherein the radio source comprises a first radio source, the method comprising the further step of automatically switching tuning of the radio from the first radio source to a second radio source having broadcast content substantially similar to the broadcast content of the first radio source, the switching being performed when the measured quality of the broadcast signal is below the threshold level.

20. The method of claim 19 comprising the further steps of:

using the processor to monitor broadcast content of the first radio source on a web site of the first radio source; and

using the processor to identify the second radio source as having broadcast content substantially similar to the broadcast content of the first radio source.
