Circuit/System Description

The P22 Video Displays are located in the back of the driver and front passenger seats. The Displays show video from the media disc player.

The Displays receive power and ground from the vehicle body harness. A discrete control circuit from the disc player is used to control the power state of the displays.

The displays receive all other video, audio and control information via the LVDS cable. The LVDS cable connected to the media disc player contains two pairs of data circuits, one pair for each of the rear displays. A splitter cable is used to separate the data circuits to each individual display, providing separate information to each display.
