Abstract: A mobile video-audio switching system mounted in a motor vehicle powered by the vehicle's 12V DC battery. A mobile video-audio switch(MVAS) device is mounted in the motor vehicle and it has four different video-audio input devices electrically connected thereto and four liquid crystal display(LCD) screens are also mounted in the motor vehicle. Four separate wireless remote control transmitters send individual signals to the MVAS device directing that signals from any of the different video-audio input devices be sent to any of the individual LCD screens. Individuals viewing the respective LCD screens can receive an audio input through a headset that they may wear or they may receive the audio signals through the radio and speaker system already installed in the motor vehicle.
