Abstract

A mobile video system includes a first video source, a second video source, a first video monitor, a second video monitor, an audio signal receiver, and a wireless transmitter. One of the first video source and the second video source generates a first audiovisual signal. One of the first video monitor and the second video monitor receives a video portion of at least one of the first audiovisual signal and the second audiovisual signal. The wireless transmitter transmits an audio portion of one of the first audiovisual signal or the second audiovisual signal to the audio signal receiver. A video portion of the first audiovisual signal or the second audiovisual signal is displayed on the first video monitor, on the second video monitor, or on both the first video monitor and the second video monitor.

Claims (30)

1. A mobile video system, comprising:

a motorized land vehicle comprising a passenger compartment, a first seat having a first headrest, the first seat positioned in the passenger compartment;

a first video source that generates a first audiovisual signal;

a second video source that generates a second audiovisual signal;

a first video monitor configured to receive a video portion of at least one of the first audiovisual signal and the second audiovisual signal, the first video monitor comprising:

a housing comprising a first hinge portion adjacent an upper edge thereof and defining a storage cavity having a floor, the floor having formed therein a plurality of apertures configured to receive fasteners for securely mounting the first video monitor to the headrest of the first seat; and

a screen structure comprising a viewing screen and a second hinge portion adjacent an upper edge thereof, the viewing screen facing the passenger compartment when the screen structure is in a stowed position, the second hinge portion cooperating with the first hinge portion to pivotably secure the screen structure to the housing such that when the screen structure is pivoted outward from the housing, access is provided to the apertures;

a second video monitor mounted in the passenger compartment, the second video monitor configured to receive a video portion of at least one of the first audiovisual signal and the second audiovisual signal;

a radio that includes a loudspeaker and that is installed in the vehicle; and

a first wireless transmitter configured to transmit an audio portion of one of the first audiovisual signal or the second audiovisual signal to the radio;

whereby a video portion of either of the first audiovisual signal or the second audiovisual signal can be displayed on the first video monitor, on the second video monitor, or on both the first video monitor and the second video monitor.

2. The mobile video system of claim 1 , wherein the plurality of apertures comprises four apertures.

3. The mobile video system of claim 1 , further comprising an aperture formed in the housing configured to receive an input cable.

4. The mobile video system of claim 1 , wherein the motorized land vehicle further comprises a second seat having a second headrest, the second video monitor mounted to the second headrest of the second seat.

5. A mobile video system, comprising:

a motorized land vehicle comprising a passenger compartment, a first seat having a first headrest, the first seat positioned in the passenger compartment;

a first video source that generates a first audiovisual signal;

a second video source that generates a second audiovisual signal;

a first video monitor configured to receive a video portion of at least one of the first audiovisual signal and the second audiovisual signal, the first video monitor comprising:

a housing comprising a first hinge portion adjacent an upper edge thereof and defining a storage cavity having a floor, the floor having an aperture formed therein;

a screen structure comprising a viewing screen and a second hinge portion adjacent an upper edge thereof, the viewing screen facing the passenger compartment when the screen structure is in a stowed position, the second hinge portion cooperating with the first hinge portion to pivotably secure the screen structure to the housing such that when the screen structure is pivoted outward from the housing, access is provided to the aperture; and

a fastener configured to be advanced through the aperture and to coupled with the headrest of the first seat to secure the first video monitor thereto;

a second video monitor mounted in the passenger compartment, the second video monitor configured to receive a video portion of at least one of the first audiovisual signal and the second audiovisual signal;

a radio that includes a loudspeaker and that is installed in the vehicle; and

a first wireless transmitter configured to transmit an audio portion of one of the first audiovisual signal or the second audiovisual signal to the radio;

whereby a video portion of either of the first audiovisual signal or the second audiovisual signal can be displayed on the first video monitor, on the second video monitor, or on both the first video monitor and the second video monitor.

6. The mobile video system of claim 5 , comprising a plurality of apertures formed in the floor of the housing and a corresponding plurality of fasteners configured to be advanced through the apertures.

7. The mobile video system of claim 6 , wherein the plurality of apertures comprises four apertures.

8. The mobile video system of claim 5 , further comprising an aperture formed in the housing configured to receive an input cable.

9. The mobile video system of claim 5 , wherein the motorized land vehicle further comprises a second seat having a second headrest, the second video monitor mounted to the second headrest of the second seat.
