Abstract

An audio information system comprising an audio player that is triggered by an RF signal. The RF signal is generated by a GPS controller that recognizes a location and sends a command to the players to play a specific track. The system consists of individual audio players and central GPS/RF transmitters. Each individual player contains all of the audio content, and the appropriate track is selected by an RF command. The GPS/RF controller contains a list of locations, and when the GPS controller is near one of the locations an RF signal is transmitted indicating which track for the audio players to play.

Claims

1. An audio information system comprising,

At least one controller, said controller having

A global positioning system receiver, and

A radio frequency transmitter electrically coupled thereto and broadcasting an audio track identification based on a position sensed by the global positioning system receiver, and

At least one audio player, said audio player having

A radio frequency receiver, and

A set of audio tracks, playback of a selected audio track being enabled by receipt of an audio track identification from said controller.

2. The audio information system of claim 1 further comprising

A plurality of controllers, and wherein

Said audio player comprises means for identifying the closest controller and accepting the audio track identification from said closest controller.

3. The audio information system of claim 2 wherein each controller broadcasts a controller identification signal.

4. The audio information system of claim 3 further comprising means for assigning sequential identifiers to adjacent controllers.

5. The audio information system of claim 4 wherein each of said controllers has a broadcast area, and each broadcast area overlaps at least each adjacent broadcast area.

6. The audio information system of claim 5 wherein each controller is mounted on a transportation vehicle.

7. The audio information system of claim 6 wherein the transportation vehicle is a train.

8. The audio information system of claim 2 wherein each controller is mounted on a transportation vehicle.

9. The audio information system of claim 8 wherein the transportation vehicle is a train.

10. The audio information system of claim 1 wherein each controller is mounted on a transportation vehicle.

11. The audio information system of claim 10 wherein the transportation vehicle is a train.
