System Description

OUTLINE
- As a unique feature of Rear Seat Entertainment (RES) system, the front and rear seat occupants can enjoy different audio-visual modes at the same time. Thus, this system offers enhanced entertainment to the rear seat occupants.
- The rear seat occupants can control the audio-visual modes with the remote controller (switch assembly), and listen to audio by using wired or wireless headphones.
- The RSE system is controlled by the multi-display controller, and the communication among the audio head unit and, rear display assembly (DVD player) is established via an AVC-LAN (Audio Visual Communication-Local Area Network).

FUNCTION OF MAIN COMPONENT

MAIN COMPONENT FUNCTION

Rear display assembly Control Panel DVD Player Headphone Terminal	Displays DVD and video images in accordance with video signals from the multi-display controller. Displays a map screen in accordance with the signals from the navigation ECU. Receives signals from the remote controller and outputs them to the multi-display controller. Outputs operation signals to the rear display to the multi-display controller. Outputs audio signals to the wireless headphones in the form of infrared signals. Outputs audio signals to the wired headphones that are connected. Adjusts the volume of the wired headphones in accordance with volume control. Displays the audio-visual control screen. Displays the adjustment screen. Displays the diagnosis screen. The diagnosis screen appears when the diagnosis mode is started on the audio head unit.
Multi-display assembly	Displays DVD and video images in accordance with video signals from the multi-display controller. Displays a map screen in accordance with the signals from the navigation ECU.
Radio receiver assembly	Outputs audio signals to the multi-display controller and the stereo component amplifier. Outputs a request to the multi-display controller to start the diagnosis mode.
Multi-display controller (Multi-display controller)	Processes video and audio signals from the DVD player and video player and audio signals from the audio head unit, and outputs them to the television display assembly and headphone terminals. Controls the distribution of the audio-visual mode to the front (audio head unit) and the rear (RSE).
Remote Controller (Switch assembly)	Outputs various control signals of the RSE system to the television display assembly in the form of infrared signals.
Wireless Headphone	Receives the audio signals from the television display assembly in the form of infrared signals. Volume adjustment of the wireless headphone can be done by using the volume equipped on the wireless headphone.
VTR terminal	This terminal is for connecting the video player's video and audio output terminals.

2. The multi-display controller functions as a master unit, which performs communication between the multi-display controller and rear display assembly, in the sub AVC-LAN circuit.
  HINT:
  
  Refer to "NAVIGATION SYSTEM" (SeeNAVIGATION SYSTEM ) and SYSTEM DESCRIPTION for the main AVC- LAN circuit.
3. The multi-display controller is equipped with a resistor (60 to 80 Ω) for communication.
DIAGNOSIS FUNCTION
1. The multi-display controller functions as a master unit in the sub AVC-LAN circuit. It identifies trouble in this circuit, and the identified information is displayed on the television display assembly.
