Description of video signal processing stage
Input signal selecting stage:
TV input;
RF signal is converted to TV_CV signal in A101(Analog Tuner) and sent to IC4001.
TV composite video signal is selected in IC4001. The output signal from IC4001 is
sent to IC5500.
Composite video input;
Composite video signal [Video1] is selected in IC4001. The output signal from IC4001
is sent to IC5500.
S-video input;
S-video Y signal [Video1]is selected in IC4001. The output signal from IC4001 is sent
to IC5500. S-video C signal is sent to IC5500. S_SW signal [Video1] is sent to IC801
and IC5500.
(Truth table of IC4001; AV_SW1/SW2: L/H=Tuner, H/L=S-video, H/H=CVBS)
Component video input;
Component video signals [Video2/3] are sent to IC6200(A/D converter). They are
selected by IIC bus, and A/D-converted in IC6200. Y signal is sync-separated in
IC6200. The output RGB digital signals are sent to IC5500.
HDMI input;
TMDS data are sent to IC5500.
Digital-TV input;
IF signals from A6120(ATSC Tuner) are converted to serial data in IC6100(TS
Demodulator), then sent to IC5500.
Video signal processing stage:
All signals are scaled and converted to RGB LVDS signals in IC5500(Scan converter), then sent to MAIN board.
LVDS signals are received in IC5201(LVDS Receiver), then sent to IC9401(Color manager). After correcting for
picture quality in IC9401 and IC401(Digital Gamma), and they are sent to IC501, IC1501, IC2501(sampling &
holding, D/A converter).
