Function
Threshold level that Phase-diffrent changes from Big to middle
is set up.
Recommendation value: [0100]
Threshold level that Phase-diffrent changes from middle to
Big is set up.
Recommendation value: [01000]
The horizontal-start-phase of the detection of Noise is set up.
“Point of 5.3µs from sync” is center.
The horizontal-width of the detection of Noise is set up.
The amount of noise-detection changes by Width.
When width is widened, detection sensitivity rises.
It is the numbers of lines which Noise is detected in.
The number of line's can be set up from 1H to 4H.
The vertical start line of the Noise detection is set up.
60Hz：7-lines as 0H.It is set up in 1 line unit.
50Hz：4-lines as 0H.It is set up in 1 line unit.
The fsc Lock-Gain is set up.
Usually used with 1/2.
Lock-period of fsc is set up.
Search-time becomes long, when it is set up ∼6V.
But, it is easy to pull in.
The position of EAV&SAV is set up.
Usually, it uses with initial-value:0[us].
V-phase of VD is set up when "H/V OUT through".
Variability of V-phase is the 1H unit.
The horizontal start phase of the picture-processing-period is
set up. The picture-processing is set up with COMBKILL
(1EH D2∼D0).
The horizontal width of the picture-processing-period is
set up. The start reference is a horizontal start phase.
Make adjustment after start-setup.
The vertical start line of the picture-processing-period is set
up.It becomes MUTE to the setup from the vertical start line.
AUTO or MANUAL is selected.
MANUAL : It becomes the value that it is set up with 1EH(D7-D4).
AUTO: 60Hz= from 10th line / 50Hz= from 23th line
Picture-processing is started from each line.
This period doesn't do picture processing.
AUTO:60Hz=1∼22H、50Hz=1∼23H
But, it is a mask period to 21H by the Y/C input of 60Hz and
the YCbCr input of 60Hz.
The start phase of H-BLANK-PULSE is set up.
Usually, it uses with initial-value:0[us].
Usually, it uses with initial-value:0[us].
