Explanation of Block Diagram
Input signal processing
RGB(1,2) & Component & VIDEO and S-VIDEO .
The RGB(D-sub15x2 or 5BNC) and COMPONENT input signals are switching output to
ADC front end(AFE1000) . After these signals and VIDEO, S-VIDEO have been
converted into 10-bit digital signals of RGB/YUV each at the A/D converter (U217) , the
resultant signals are output to the scaler (U001).
Digital input system
HDMI/Displayport
The HDMI/Displayport signals input to HDMI switch (U408) then output to HDMI receiver
(U409). The signals are further converted
into 10-bit digital signals of RGB/YCbCr, and then output to the scaler (U001).
Output signals processing
RGB out(D-sub15 black) .
The RGB output signals pass through from VGA1 only by analog switching Ics
(ADA4862).
