This board is mounted onto the motherboard as shown in the picture in section 4
The module provides multiple functions including: - COFDM demodulator, MPEG decoder, PAL/NTSC
encoding, ASI/SDI routing, Analog audio D/A converter, AES audio encoder, Genlock, and user data
extraction.
The heart of the unit is an FPGA which deals with signal routing and control.
The video, audio, and data outputs are routed via the motherboard to the rear panel of the receiver.
The unit is controlled by the Front Panel display module.
