Abstract

A mobile video system for a vehicle is provided. The mobile video system includes a video source, a monitor, a radio, a wireless transmitter, and a manual actuator. The monitor receives a video signal from the video source and generates a visual display based thereon. The radio is installed in the vehicle and includes at least one loudspeaker. The wireless transmitter transmits an audio signal from the video source to the radio via an FM transmission on a. FM frequency. The manual actuator selects the FM frequency. The manual actuator is operable by a passenger within the vehicle. The passenger can thereby change the FM frequency when the passenger perceives that the FM transmission is subject to interference.

Claims

1. An audiovisual system for a vehicle having a vehicle seat including a headrest, the audiovisual system comprising:

at least one audio signal receiver;

a video monitor adapted to be mounted to the headrest of the vehicle seat;

a video signal transmitter adapted to provide a selected video signal from at least one video source to the video monitor for display;

a wireless audio transmitter that transmits a selected audio signal related to the selected video signal to the at least one audio signal receiver on a selected frequency; and

a manually operated audio frequency selector that selects the selected frequency.

2. The audiovisual system of claim 1, wherein the audio frequency selector comprises a button that is wired to the wireless audio transmitter.

3. The audiovisual system of claim 2, wherein the audio frequency selector is at least partially positioned within a housing for the video monitor.

4. The audiovisual system of claim 1, wherein the frequency selector comprises a remote control device.

5. The audiovisual system of claim 1, further comprising an audio frequency indicator that indicates the selected frequency.

6. The audiovisual system of claim 5, further comprising a housing for the video monitor, the audio frequency indicator positioned within the housing.

7. The audiovisual system of claim 5, further comprising a housing for the audio frequency indicator, the housing adapted to be mounted to the headrest of the vehicle seat.

8. The audiovisual system of claim 5, further comprising a remote control device, the audio frequency indicator positioned on the remote control device.

9. The audiovisual system of claim 1, wherein the transmitter comprises a frequency modulation (FM) transmitter.

10. The audiovisual system of claim 1, wherein the transmitter comprises a radio-frequency transmitter.

11. The audiovisual system of claim 1, wherein the video monitor is adapted to be adjustably mounted to the headrest of the vehicle seat.

12. The audiovisual system of claim 11, wherein an angular orientation of the video monitor relative to the headrest is adjustable without moving the headrest.

13. The audiovisual system of claim 1, further comprising a wireless infrared audio transmitter.

14. The audiovisual system of claim 1, wherein the at least one audio signal receiver comprises a radio.

15. The audiovisual system of claim 14, wherein the radio is coupled with loudspeakers that are installed in the vehicle.

16. The audiovisual system of claim 1, wherein the at least one audio signal receiver comprises a set of headphones.

17. The audiovisual system of claim 1, wherein the at least one audio signal receiver comprises two sets of headphones.

18. The audiovisual system of claim 1, further comprising a digital video disc player coupled with the video signal transmitter.

19. The audiovisual system of claim 18, further comprising a video game console coupled with the video signal transmitter.

20. The audiovisual system of claim 1, further comprising a video game console coupled with the video signal transmitter.

21. The audiovisual system of claim 1, further comprising a video cassette player coupled with the video signal transmitter.

22. A mobile video system for a vehicle having a headrest, comprising:

a video source;

a monitor that receives a video signal from the video source and that generates a visual display based thereon, the monitor being mounted in the headrest of the vehicle;

a radio including at least one loudspeaker, the radio being installed in the vehicle;

a wireless transmitter that transmits an audio signal from the video source to the radio via an FM transmission on a FM frequency; and

a manual actuator that selects the FM frequency, the manual actuator being operable by a passenger within the vehicle, thereby permitting the passenger to change the FM frequency when the passenger perceives that the FM transmission is subject to interference.
