Signal Flow
(1) CVBS, Y/C
CVBS (Composite Video) or Y/C signal from AV1 or AV2 terminal is input to AV SW IC (IC1001) and selected
signal.
CVBS signal selected by IC1001 is input to 3 Dimension Y/C Separation IC (IC7101) and input to IC1001 again.
(In case of NTSC Signal) On the other hand it is input to Digital Decoder IC (IC401) and output for Monitor Out
signal (CVBS only).
(2) RGB, Component
RGB or Component signal from PC1 or PC2 (AV4) terminal is input to RGB / Component SW IC (IC1123,
IC1124) and selected signal.
(3) Decoder, I/P Conversion
CVBS or Y/C signal from IC1001 or Component signal (480i) from IC1124 input to Digital Decoder IC (IC401).
Component signal from IC401 is input to I/P (interlace / Progressive) Conversion IC (IC501) and converted.
(4) A/D Conversion
RGB ( or Progressive Component) signal from IC1124 is input A/D Conversion IC (IC207) and converted.
(5) Panel Drive
Signal from IC501 or IC207 is input to RGB Matrix IC (IC601) and proceeded for picture control.
Signal from IC601 is input to Main Scaler IC (IC301) and LVDS Interface IC (IC751) and input to PDP Panel
Module.
