5-6-1 Outline

VIC50 sends VSYNC and HSYNC from VIC1(A/V decoder) and receives 8bit video data.
VIC50 does RGB encoding, copy guard processing and D/A conversion of 8bit video data inputted from VIC1(A/V
decoder) by control of MIC1(Micom).
Video signal converted into analog signal is outputted via amplifier of analog part.
