Method of determining station status of non-audible tuner in dual-tuner system

1. A vehicle entertainment system capable of receiving a range of wireless frequencies and providing an audio output signal associated with a particular frequency selected from the range of wireless frequencies, said vehicle entertainment system comprising:

an operator interface including a display and a plurality of preset buttons wherein each preset button is associated with a particular stored frequency selected from the range of wireless frequencies;

a first tuner providing the audio output signal associated with the particular frequency selected from the range of wireless frequencies;

a second tuner capable of scanning each of the particular stored frequencies associated with each of said plurality of preset buttons and wherein said second tuner provides an output signal to a frequency analyzer and wherein said frequency analyzer provides a status signal to said operator interface related to the status of at least one of the particular stored frequencies and associated with at least one of the plurality of presets wherein the status is related to the type of content currently being broadcast on said at least one of the particular stored frequencies and wherein said operator interface provides a visual indicator associated with the at least one preset in response to said status signal.

2. The vehicle entertainment system of claim 1 wherein the range of wireless frequencies is selected from one of AM band, FM band, internet radio and satellite radio.

3. The vehicle entertainment system of claim 1 wherein said stored frequency is a channel on satellite radio.

4. The vehicle entertainment system of claim 1 wherein each of said preset buttons includes at least two backlight light sources, and wherein said at least two backlight light sources are said visual indicators.

5. The vehicle entertainment system of claim 4 wherein each of said backlight sources emits a different light color.

6. The vehicle entertainment system of claim 5 wherein said at least two backlight sources include a first colored light source and a second colored light source and wherein said status signal includes a first status signal and a second status signal and wherein said first colored light source illuminates in response to said first signal and said second colored light source in response to said second signal.

7. The vehicle entertainment system of claim 1 wherein said visual indicator is a symbol on said display in proximity to an associated preset button of said preset buttons.

8. The vehicle entertainment system of claim 7 wherein said symbol is a colored output.

9. The vehicle entertainment system of claim 7 wherein said symbol is a graphical symbol on said display.

10. The vehicle entertainment system of claim 9 wherein said graphical symbol is one of a person's head, a music note, a music instrument, a symbol for commercials, and a cloud.

11. The vehicle entertainment system of claim 1 wherein said status signal identifies the type of content currently being broadcast as one of talk content and music content.

12. The vehicle entertainment system of claim 11 wherein the type of content currently being broadcast is talk content and said status signal identifies the talk content is at least one of talk show, sports radio, commercial or undetermined.

13. The vehicle entertainment system of claim 11 wherein the type of content is music and said status signal identifies the type of music currently being broadcast.

14. A method of determining the status of individual selected frequencies, each individual selected frequency being associated with a preset button of an entertainment system, comprising the steps of:

providing an output signal from a first tuner;

analyzing the individual selected frequencies with a second tuner;

determining the current status of content on each of said individual selected frequency analyzed during said step of analyzing the individual selected frequencies;

providing a visual indicator output of the current status of each individual selected frequency determined during said step of determining the status of each individual selected frequency.

15. The method of claim 14 further including the step of repeating said steps of analyzing, determining and providing a visual indicator at predetermined intervals.

16. The method of claim 14 wherein said steps of analyzing, determining and providing a visual indicator are performed while said step of providing an output signal is simultaneously being performed.

17. The method of claim 14 wherein said step of providing an output signal further includes the steps of tuning the first tuner to a particular frequency and maintaining the particular frequency without system interference while said steps of analyzing, determining and providing a visual output are being performed.

18. The method of claim 14 further including the step of maintaining the provided audio output to a particular frequency until receiving a manually inputted instruction to change the particular frequency to a different frequency.

19. The method of claim 14 wherein said step of providing a visual indicator further includes the step of changing the backlight color of a preset button.

20. The method of claim 14 wherein said step of providing a visual indicator includes the step of visibly changing a user interface of the entertainment system proximate to the preset buttons.

21. The method of claim 14 wherein said preset buttons include the seek and scan buttons and wherein the selected frequencies are the adjacent frequency to the frequency to which the first tuner is tuned.

22. The method of claim 21 further including the step of only analyzing individually selected frequencies and the adjacent frequencies to the frequency to which the first tuner is tuned.

23. The method of claim 14 wherein said step of determining the current status includes the step of determining whether music content or talk content is being currently provided.

24. The method of claim 23 wherein the step of determining whether music or talk content is being currently provided further includes the step of determining talk content is being provided and determining the type of talk content.

25. The method of claim 24 wherein the step of determining the type of talk content includes the step of determining at least one of voice content or commercial content.

26. The method of claim 25 wherein said step of determining voice content further includes the step of determining at least one of talk show content, sports radio content.

27. The method of claim 23 wherein the step of determining music or talk content further includes the step of determining music content and further includes the step of determining the type of music content.
