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