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

1-11. -11. (canceled)

12. A mobile video system comprising:

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

a first video source that generates a first audiovisual signal and comprises a first video output;

a second video source that generates a second audiovisual signal and comprises a first video output;

a first video monitor mounted in the passenger compartment, the first video monitor comprising a first primary video input and a first secondary video input;

a second video monitor mounted in the passenger compartment, the second video monitor comprising a second primary video input and a second secondary video input;

a first communication line connecting the first video output to the first primary video input and the second primary video input; and

a second communication line connecting the second video output to the first secondary video input and the second secondary video input;

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.
