4-2-3. DTV/DVD signal

Both DTV(Y, Pb, Pr) and DVD(Y, Cb, Cr) share same jack and signal path. Main and Sub in
PIP mode have same path. ICI3 switches out signal and also detects type of signal so that
ICA10 can convert the analog signal to digital. Then the signal goes through ICS1 for the
image processing.
