One of the component1 and 2 video signals received in P201 is selected by the video switch(IC202) and sent to
Analog to Digital converter(IC201).
The analog signal received in IC201 is converted to the digital signal and sent as output in 24 bit.
The digital signal of 24bit is received in DTV controller(IC401) and decoded to convert to LVDS signal and sent to
the LCD panel through LVDS connector.
Also because the caption information in the component signal received in IC202 is in Y signal, the Y signal is sent to
the analog video switch of IC706 to be sent to IC401 through IC107 and IC705.
