/* There are two bits of information that the driver needs in order
to select the correct routing : the operating mode and the selection
of the Y input ( external or internal ) .
The first two operating modes expect a composite signal on the Y input ,
the second two operating modes use both the Y and C inputs .
Normally YCS_MODE is used for tuner and composite inputs , and the
YCNR mode is used for S - Video inputs .
The external Y - ADC is selected when the composite input comes from a
upd64031a ghost reduction device . If this device is not present , or
the input is a S - Video signal , then the internal Y - ADC input should
be used . */
