Fixed value.
021-F BDRIVE
B channel drive gain control. Range:
0- 63, 0H = -4.2 dB, 29H = 0 dB, 3FH = +2.1 dB.
Fixed value.
022-F RCUTOFF
R channel cutoff control Range:
0-63, 0H = -9.1dB, 1FH = 0 dB, 3FH = +4.4 dB.
Fixed value.
023-F GCUTOFF
G channel cutoff control Range:
0-63, 0H = -9.1dB, 1FH = 0 dB, 3FH = +4.4 dB.
Fixed value.
024-F BCUTOFF
B channel cutoff control Range:
0-63, 0H = -9.1dB, 1FH = 0 dB, 3FH = +4.4 dB.
Fixed value.
025-F BLKBTM
RGB-OUT bottom limiter level con-
trol (valid when BLKSW = 1). The limiter level
is replaced with the reference DC for each H in
RGB system, and the drop voltage from that DC
defines it; it is not dependent on DC level
control setting made by BRIGHT, etc. This lim-
iter functions for all video signals. For fur-
ther details, refer to the description of opera-
tion. Range: 0-3.
026-F PICTURE:
Picture gain control. Range:
0-63.
027-F BRIGHTNESS:
Brightness level range: 0-
63.
028-F GAMMA
Control of gamma correction amount.
0H = OFF. 3H = MAX.
029-F DCOL:
Dynamic color mode setting. Range:
0 = OFF, 1 = ON, R:98%, G:100%, B:102.5%.
030-F PLIMITLEV:
Setting of level detection DC
at RGBOUT of PEAK-ABL. 0 = 115IRE.
031-F WBSW:
White balance offset setting. 0=off,
normal color temperature.
032-F CTILEV AUX:
Chrominance transient im-
provement for Aux video input.
033-F CTIMODE AUX:
Chrominance transient mode
for Aux video input.
034-F COLAXIS:
Color detection axis setting. 0=
for NTSC.
035-F GAMMAL:
Fine tuning for gamma.
036-F LTILEV AUX:
Luminance signal edge en-
hancement setting for Aux video inputs. Range:
0-3, 0 = OFF, 1 = Low, 2 = Medium, 3 = High.
037-F LTIMODE AUX: Luminance transient im-
provement for aux video inputs. Default value
in 1.
038-F SYSTEM AUX:
Signal frequency band switch-
ing; select the band in accordance with the TV
System. Range: 0- 3, 0 = NORMAL, 1 = FF, 2 = HD,
3 = FIX-HD (setting which gives greater impor-
tance to frequency response than 2).
039-F DCTRAN:
Y system DC transmission ratio
setting. Range: 0-3, 2 = 90%.
040-F YOFFSET:
DC offset canceling for y sig-
nal. Default value is 7.
041-F DPICLEV:
Dynamic picture (black expan-
sion) control. Range: 0-3, 0 = OFF, 1 = Low:
inflection point 25 IRE, 2 = Medium: inflection
point 30 IRE, 3 = High: inflection point 35 IRE.
042-F LRGB2LEV:
LRGB2 system picture level con-
trol. Range: 0-15, 0H = -8 dB, Fh = 0 dB.
043-F ABLMODE:
Switch for ABL mode. Range: 0-3,
0 = Picture ABL only mode, 1 = Picture/bright-
ness ABL mode: Low, 2 = Picture/brightness ABL
mode: Medium, 3 = Picture/brightness ABL mode:
High.
044-F ABLTH:
Adjustment of threshold voltage
for ABLIN (Pin 44) input. Range 0-15. Default
value is 2.
045-F PABL:
RGB output level detection DC set-
ting for peak ABL. Default value is 15d.
046-F CBOFFSET:
For canceling the offset be-
tween CrCb of IN1 and SELIN systems. Range: 0-
63. This variable range is DC variation amount
of respective input pins.

For canceling the offset be-
tween CrCb of IN1 and SELIN systems. Range: 0-
63. This variable range is DC variation amount
of respective input pins.
