Abstract

A channel mapping system has a data source containing data indicative of the geographic range of channels broadcast in at least one selected region and a channel determination module that uses data indicative of a location in conjunction with the data source to determine a preferred channel. The preferred channel may be an FM channel. A transmitter is used with a portable media player to broadcast audio data contained on or received by the portable media player over the preferred channel. The media can be received by a corresponding receiver set to the same preferred channel. Adjustments to the channel settings can be determined repeatedly so that, as a preferred channel changes with location, an automated process or a user facilitated process can be used to change the channel settings on each of the transmitter and the receive. A location identification system such as GPS can be used to identify the location.

Claims

1. A preferred channel determination system, comprising:

a data source containing data indicative of the geographic range of channels broadcast in at least one selected region and route information that indicates a user'"'"'s expected travel route; and

a channel determination module in communication with the data source, the channel determination module operable to use the data indicative of the geographic range of channels broadcast in at least one selected region to determine a preferred channel for use in transmission at a given location and configured to use the route information to determine preferred channels for certain portions of a user'"'"'s trip.

2. A system as defined in claim 1, wherein the channels broadcast in at least one selected region comprise FM channels and the preferred channel for a given location comprises an FM channel.

3. A system as defined in claim 1, wherein the channels broadcast in at least one selected region comprise DAB channels and the preferred channel for a given location comprises and a DAB channel.

4. A system as defined in claim 1, further comprising an FM transmitter in communication with the channel determination module, the FM transmitter operable to broadcast media received from a portable media player over a selected FM channel.

5. A system as defined in claim 4, further comprising means for communicating the selected FM channel to a user.

6. A system as defined in claim 4, further comprising a location identification device operable to identify the location of the FM transmitter.

7. A system as defined in claim 1, further comprising:

an FM receiver in communication with the channel determination module, the FM receiver operable to receive media transmitted over a selected FM channel.

8. A system as defined in claim 7, further comprising means for communicating the selected FM channel to a user.

9. A system as defined in claim 7, further comprising a location identification device operable to identify the location of the FM receiver.

10. A system as defined in claim 1, further comprising a satellite radio player and an FM transmitter integrated in a single device with the channel determination module.

11. A system as defined in claim 1, further comprising an FM transmitter and a device selected from a car stereo and a digital audio player integrated in a single device with the channel determination module.

12. A system as defined in claim 1, further comprising a video player, configured to output the audio portion of selected video content such that it can be played by a different device, integrated in a single device with the channel determination module and a radio transmitter.

13. A system as defined in claim 1, further comprising a module for providing an audible cue to direct a user to change a channel setting on at least one of a transmitter and a receiver in response to correspond to the preferred channel.

14. A system as defined in claim 1, further comprising a module for providing a visible cue to direct a user to change the channel setting of at least one of a transmitter and a receiver.

15. A method for facilitating the transmission of media between an FM transmitter and an automotive radio, comprising:

providing a portable media player, the portable media player having or being operable to receive selected media content;

providing a transmitter in communication with or integrated with the portable media player, the transmitter operable to broadcast media received from the portable media player over a range of channels;

at a channel determination module, upon receiving data indicative of the location of the transmitter and route information indicative of a user'"'"'s expected travel route, accessing a database to identify data related to the channel and broadcast range of area stations and using the route information to thereby determine a preferred channel for use in transmission at the indicated location and for certain portions of a user'"'"'s trip; and

directing the adjustment of the transmitter and a corresponding receiver to the preferred channel.

16. A method as defined in claim 15, wherein the preferred channel comprises an FM channel and the transmitter and corresponding receiver are an FM transmitter and an FM receiver.

17. A method as defined in claim 15, wherein the data indicative of the location of the transmitter is determined by a GPS device.

18. A method as defined in claim 17, wherein the transmitter, the channel determination module, and the GPS device are integrated in a single device.

19. A method as defined in claim 15, wherein the portable media player comprises a satellite radio player.

20. A method as defined in claim 15, wherein the portable media player is a digital audio player.

21. A method as defined in claim 15, wherein the portable media player is a video player and the transmitter is configured to broadcast the audio portion of selected video content.

22. A method as defined in claim 15, further comprising the act of providing an audible cue to direct a user to change the channel setting of at least one of the transmitter and the receiver.

23. A method as defined in claim 15, further comprising the act of providing a visible cue to direct a user to change the channel setting of at least one of the transmitter and the receiver.

24. In a computer system that is adapted for use in conjunction with a transmitter, a computer readable medium encoded with computer executable instructions for performing a method for determining a preferred channel for use in local transmission, the method comprising:

receiving data indicative of the actual location of a transmitter;

accessing a data source to identify data related to stations which broadcast in the actual location of the transmitter and locations adjacent to the actual location of the transmitter;

using the data indicative of the actual location of a transmitter and the data related to stations which broadcast in the actual location of the transmitter and locations adjacent to the actual location of the transmitter, determining a preferred channel for use in local transmission by selecting a channel that is clear in both the actual location of the transmitter and locations adjacent to the actual location of the transmitter; and

directing the adjustment of the transmitter and a corresponding receiver to the preferred channel.
