Abstract
The present invention is a method and apparatus for providing a vehicle entertainment control system that controls a plurality of display units. The vehicle entertainment control system includes a remote override control circuit capable of activating a remote signal for moving at least one of the plurality of display units between a first position and a second position. In addition, the vehicle entertainment control system includes a local display unit movement control circuit coupled to one of the plurality of display units. The local display unit movement control circuit includes a photodiode coupled to said local display unit movement control circuit, the photodiode transmits a light beam capable of being reflected from a reflective surface near the photodiode to make a reflected light beam, and a photodetector coupled to the local display unit movement control circuit, the photodetector providing a signal to the local display unit control circuit upon detection of said reflected light beam to move the one of the display units between the first position and the second position.
