2.
DRVOUT(IC101-3) from CCD BD is A/D Converted and handled by Digital Camera Processing, then it goes
to Encoding block.
3.
Encoding block does digital encoding and this signal goes to D/A Converting block.
4.
In D/A Converting blcok, digital signal is changed to analog signal, so Y signal
(IC101-75(IOY)) and
C signal(IC101-67(IOC)) is output.
