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, compromising 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;

using the processor to record broadcast content of the radio source from a web site of the radio source, the broadcast content being recorded only if;

the measured quality of the broadcast signal is above a threshold level; and

the radio has been tuned to the radio source for greater than a threshold amount of time; and

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

2. The method of claim 1 wherein the quality of the broadcast signal is dependent upon at least one of field strength, level of multipath, and ultrasonic noise.

3. The method of claim 1 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 only if the measured quality of the broadcast signal is below the threshold level.

4. The method of claim 3 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.

5. 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 quality of the broadcast signal from the vehicle to the processor;

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

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

providing a user an option to select time shift as an option for a configuration of the radio, the broadcast content being recorded only if the user has selected time shift as an option for a configuration of the radio.

6. The method of claim 5 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.

7. 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;

using the processor to record broadcast content of the radio source from a web site of the radio source, the broadcast content is recorded only if the radio source has been stored a preset frequency and/or the radio has been tuned to the radio source form than a threshold amount of time;

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

providing a user an option to select time shift as an option for a configuration of the radio, the broadcast content being recorded only if time shift is currently selected as the configuration of the radio.

8. The method of claim 7 wherein the broadcast content is recorded only if the measured quality of the broadcast signal is above a threshold level.

9. The method of claim 7 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 7 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 only if the measured quality of the broadcast signal is below the threshold level.

11. The method of claim 10 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.
