Abstract

A mobile video system is disclosed. The mobile video system includes: a radio that includes a loudspeaker configured to output a signal received by the radio; a video source that generates an audiovisual signal; and a video monitor configured to receive a video portion of the audiovisual signal. The video monitor includes: a housing sized be positioned within the headrest, the housing comprising a first hinge portion and defining a storage cavity; a screen sized and shaped to be positioned within the storage cavity, the screen structure comprising a second hinge portion configured to cooperate with the first hinge portion to secure the screen structure to the housing; a first transmitter configured to transmit an audiovisual signal to a first receiver, wherein the first receiver is the radio; and a second transmitter configured to transmit the audiovisual signal to a second receiver.

First claim

What is claimed is:

1. A mobile video system comprising:
a video monitor configured to receive a video portion of an audiovisual signal from a video source separate from the video monitor;
a first transmitter configured to wirelessly transmit an audio portion of the audiovisual signal to a first receiver, the first transmitter being mounted to the video monitor and configured to transmit at a first frequency band;
a second transmitter configured to wirelessly transmit the audio portion to a second receiver different from the first receiver, the second transmitter being mounted on the video monitor and configured to transmit at a second frequency band different from the first frequency band; and
a manually operated audio frequency selector operable so that the second transmitter optionally transmits the audio portion of the audiovisual signal at a third frequency band,
wherein the first frequency band, the second frequency band and the third frequency band do not overlap one another.

2. The mobile video system of claim 1 , wherein the first receiver is a personal speaker system.

3. The mobile video system of claim 2 , wherein the personal speaker system includes a headphone.

4. The mobile video system of claim 1 , further comprising a remote control, wherein the manually operated audio frequency selector is mounted to one of the video monitor and the remote control.

5. The mobile video system of claim 1 , wherein the video source comprises a DVD player.

6. The mobile video system of claim 1 , wherein the video source comprises a video game console.

7. The mobile video system of claim 1 , wherein the first transmitter comprises a radio frequency transmitter.

8. The mobile video system of claim 1 , wherein the first transmitter comprises an infrared transmitter.

9. The mobile video system of claim 1 , wherein the second receiver is radio operable so as to receive one of the audio portion of the audiovisual signal transmitted by the second transmitter and a broadcast radio station signal.

10. The mobile video system of claim 1 , further comprising an audio frequency indicator mounted to the video monitor and configured to provide a visual signal of the transmission frequency band selected by the manually operated audio frequency selector.

11. The mobile video system of claim 4 , further comprising an audio frequency indicator mounted to the remote control and configured to provide a visual signal of the transmission frequency band selected by the manually operated audio frequency selector.

12. The mobile video system of claim 1 , wherein the video source includes an audio output, the mobile video system further comprising a jack separate from the video source and the video monitor and configured to be connected to the audio output of the video source and the first transmitter.

13. The mobile video system of claim 1 , wherein the video monitor is configured to be mounted into a headrest of a seat, wherein the headrest is configured to be coupled detachably to the seat.

14. The mobile video system of claim 1 , further comprising a seat having a headrest with the video monitor mounted thereon, wherein the headrest is integral with the seat.

15. The mobile video system of claim 1 , wherein the video monitor includes:
a housing sized and shaped to be substantially positioned within a headrest, the housing including a first hinge portion and defining a storage cavity; and
a screen structure sized and shaped to be substantially positioned within the storage cavity, the screen structure including a second hinge portion configured to cooperate with the first hinge portion to pivotably secure the screen structure to the housing.

16. The mobile video system of claim 1 , wherein the first transmitter is configured to transmit the audio portion of the audiovisual signal to a speaker connected to a radio of a motor vehicle.

17. The mobile video system of claim 16 , wherein the first transmitter is a frequency modulation (FM) transmitter.

18. The mobile video system of claim 1 , wherein the video monitor further comprises an input cable comprising a multi-pin connector.

19. The mobile video system of claim 1 , wherein the manually operated audio frequency selector is mounted to the video monitor.

20. The mobile video system of claim 19 , wherein the manually operated audio frequency selector is included in a cluster of manual controls mounted to the video monitor.
