13-2-3 Analog Board Block Description
■ Analog Video Signal Processing
■ Select Sound/Video
One is selected from multiple inputs by the switching ID. MICOM decides which port is used for output.
For broadcasting signals, sub-outputs are transferred in CVBS and, the main outputs in Y/C through the 3D Comb, to the digital
board.
Sound signals are selected by the switching IC, of which only one input is transferred to the speaker.
■ Detection Signal Flow
When each port is connected to a signal cable, the detection signal is "low" and can be checked by Micom scanning.
