Task
- Receive signals
- Demodulating and decoding signals
- Transmit signals
Receive signals
- Direct lines
- CAN (with code (864) Rear entertainment system)
- Media Oriented System Transport (MOST)
Direct lines
- Power supply via terminal 31 and terminal 30g
- Electronic wake-up via a direct line
- TV 1 antenna amplifier (A94/1) via a coaxial cable
- TV 2 antenna amplifier (A94/2) via a coaxial cable
- TV 3 antenna amplifier (A94/3) via a coaxial cable
CAN (with code (864) Rear entertainment system)
The TV tuner (analog/digital) is a subscriber of the telematics CAN (CAN A) and communicates with the following control units:
- Left rear display (A40/5)
- Right rear display (A40/6)
- DVD player (A40/4)
Media Oriented System Transport (MOST)
The TV tuner (analog/digital) is a subscriber of the MOST, via which it communicates with the COMAND operating, display and controller unit (A40/3).
Demodulating and decoding signals
The received TV signals are evaluated internally and separated into video and audio signals.
Transmit signals
- Direct line
- CAN (with code (864) Rear entertainment system)
- MOST
Direct line
- Phantom power supply to following antenna amplifiers:
- TV 1 antenna amplifier
- TV 2 antenna amplifier
- TV 3 antenna amplifier
- Transmit video signals to the COMAND controller unit via Y/C lines
- Transmit video signals via Y/C lines to the DVD player (with code (864) Rear entertainment system)
- Transmit audio signals to the DVD player (with code (864) Rear entertainment system)
CAN (with code (864) Rear entertainment system)
The TV tuner (analog/digital) is a telematics CAN subscriber and it communicates with the following control units:
- Left rear display
- Right rear display
- DVD player
MOST
The TV tuner (analog/digital) is a subscriber of the MOST, via which it communicates with the COMAND controller unit. The audio signals are transmitted to the COMAND controller unit or the sound system amplifier control unit (N40/3) (with code (810) Sound system).
