4-2. Overview
A/V block (Main and Sub PCB) is Multi Media circuit board that can process various input
signals such as video, component, PC, DVI, and analog TV signal. It is mainly composed
of switching, sync processing, decoding, analog TV, digital image processing, and system
control part.
4-2-1. Composite video, Y/C(S-Video) and SCART(CVBS, RGB) composite video
Y/C(S-Video) and SCART(CVBS) have similar signal paths. For the Main signal, IC201
receives these inputted signals and switches out a selected signal. Then the signal goes
into ICV10 for video processing, SCART(RGB) signal goes directly into ICV10. The output
of ICV10 goes through ICS1 for de-interlacing and digital image processing respectively.
However, at PIP mode, sub signal has a little bit different path from the Main signal. First of
all, IC201 receives input signals such as composite video, Y/C or etc, and switches out the
selected signal like as the Main signal. But the selected signal goes into ICS1 for video
processing and image processing instead of going into ICV10.
