- with CODE (498) Japan version

Component Identification:

Location
The TV digital tuner is located in the trunk on the right side wall behind the paneling on a bracket. With model 204.9 the TV digital tuner is located in the trunk on the left side wall behind the paneling on a bracket

The TV digital tuner is delivered with a "B-CAS card". The card slot in the TV digital tuner is sealed with a cap to prevent unintended removal of the "B-CAS card".

Task
In addition to the TV reception, the TV digital tuner also supports the following functions:
- "Electronic Program Guide" Enables reception and display of information about the broadcast (e.g. title, time, duration of broadcast, encryption, program category, age restriction, etc.).
- Broadcast Markup Language (BML) Enables the reception and structured display of information that is sent by the available stations (e.g. on the weather, news, traffic information, etc.). Reception of regional information is also possible.
- 2 languages are supported, depending on station availability (e.g. Japanese and English).

The TV digital tuner performs the following tasks:
^ Reception of signals
^ Demodulating and decoding signals
^ Transmission of signals

Receive signals
^ Direct lines
^ media-oriented system transport (MOST)

Direct lines
- Power supply via circuit 31 and circuit 30g using one direct line each
- Electronic wake-up for MOST via a direct line
- TV 1 antenna amplifier and DAB Band III (A94/1)
- TV 2 and Keyless-Go antenna amplifier (A94/2) (model 204.0/9) or TV 2 antenna amplifier (A94/2) (model 204.2)
- TV 3 antenna amplifier (A94/3)

MOST
The TV digital tuner is a subscriber of MOST and communicates with the COMAND controller unit (A40/3).

Demodulating and decoding signals
The TV signals are evaluated internally and separated into video and audio signals.

Transmission of signals
^ Direct line
^ MOST

Direct line

- Phantom voltage to the following amplifiers:
- TV 1 and DAB Band III antenna amplifiers TV 2 and Keyless-Go antenna amplifier (model 204.0/9) or TV 2 antenna amplifier (model 204.2)
- TV 3 antenna amplifier

- Transmission of video signals via a Y-brightness (luminance)/C-color information (chrominance) (Y/C) line to the COMAND controller unit

MOST
The TV digital tuner is a subscriber of MOST and communicates with the COMAND controller unit.
