S-Video signal is received through P101 jack.
Y signal and C signal are separated in this signal and is received directly by DTV controller(IC401) and decoded by
IC401 to convert to LVDS signal.
Then it is sent to the LCD panel through P503.
And the caption signal is send to IC401 through the video filter (IC107) and microprocessor(IC705) via analog video
switch(IC706).
The audio signal of S-Video is used as the audio signal of AV3.
