- with CODE (863) Digital/analog TV tuner
Component Identification
Location
The TV combination tuner is located on a bracket in the trunk on the right sidewall behind the paneling.
Task
The TV combination tuner has the following tasks:
^
Reading in analog and digital TV signals
^
Evaluating input factors
^
Output of output values
^
Exchange of control commands and transfer of audio signals (PCM format) and data for the auxiliary TV services (e.g. videotext, DVB-T-data
services)
Reading in analog and digital TV signals
The input values are read in over the following discrete lines:
-
Power supply via circuit 31 and circuit 30g over one direct line each
-
Electronic wake-up for Media Oriented System Transport (MOST) via one direct line
-
Analog and digital TV signals over a coaxial line by TV antennas 1 to 4 via the left antenna amplifier module (A2/64) and the right antenna
amplifier module (A2/65)
Evaluation of input factors
The amplified TV signals are evaluated internally and separated into video and audio signals.
Output of output values
The output values are output over the following discrete lines:
-
Control/power supply antenna amplifier
-
Y/C line (video output)
-
Left and right analog audio
