Signal processing of the TV sound
The headphones module is equipment attached to the MOST bus. The MOST bus connects the control modules for the information and communications systems of the vehicle.
The headphones module is the interface between the MOST bus and the control module for the rear seat entertainment system (RSE control module).
The video module for analog and digital television (video module hybrid DRIVE) receives the TV signals via the TV antennas.
Whereas the picture signals are sent from the video module via the CVBS or RGB line directly to the RSE control module, the video module sends the TV sound as a message (optical signal) on the MOST bus.
The headphones module transforms the optical signal into an analog signal. The headphones module transfers the TV sound as an analog signal via the audio lines to the RSE control module. The RSE control module regulates the audio output of the TV sound for the rear seat entertainment system (RSE).
