Task
The digital TV tuner has the following tasks:
- Reading in digital TV signals
- Evaluating input factors
- Output of output values
- Exchange of control commands and transfer of audio signals and data for the auxiliary TV services (e.g. videotext, DVB-T data services)
Reading in digital TV signals
The input factors are read in with the following connections:
- Antennas for reception of digital TV signals
- Digital TV signals via:
- TV 1 and TV 2 antenna (model 211.0, 219)
- Left antenna amplifier module (A2/64)
- TV 3 and TV 4 antenna (model 211.0, 219)
