24 | /* There are two bits of information that the driver needs in order | |
25 | to select the correct routing: the operating mode and the selection | |
26 | of the Y input (external or internal). | |
27 | ||
28 | The first two operating modes expect a composite signal on the Y input, | |
29 | the second two operating modes use both the Y and C inputs. | |
30 | ||
31 | Normally YCS_MODE is used for tuner and composite inputs, and the | |
32 | YCNR mode is used for S-Video inputs. | |
33 | ||
34 | The external Y-ADC is selected when the composite input comes from a | |
35 | upd64031a ghost reduction device. If this device is not present, or | |
36 | the input is a S-Video signal, then the internal Y-ADC input should | |
37 | be used. */ | |
