and Chroma Clip controls are enabled and clip any luma/chroma that exceed the
set limits. In RGB mode only the White Clip and Black Clip controls are active and
limit the R, G, and B values to those settings. RGB mode requires the video to pass
through the RGB Proc Amp to be converted to and from RGB.

Enables the Video Legalizer to clip RGB to legal levels.
3.1 Legalizer White Clip
When the Video Legalizer mode is YUV or RGB, this parameter limits the white
level so that it does not exceed the adjusted limit. Limit can be set from +80 IRE to
+120 IRE.
Variable
Adjusts white clip level from +80 IRE to +120 IRE in 0.5 steps.
Default (unity):
100 IRE
3.2 Legalizer Black Clip
When the Video Legalizer mode is YUV or RGB, this parameter limits the black
level to the adjusted limit. Limit can be set from -10 IRE to +20 IRE,.
Variable
Adjusts black level limit from -10 IRE to +20 IRE in 0.5 steps. Default
(unity): 0 IRE
3.3 Legalizer Chroma Clip
When the Video Legalizer mode is YUV, this parameter limits the maximum
chroma level to the adjusted limit. The limit can be set from +60% to +140%,.
Variable
Adjusts chroma clip level from +60% to +140% in 0.5 steps. Default
(unity): 100 IRE
Blank
In Blank mode, the FS-HDR copies and remembers the contents of SD line 21
and then blanks those lines before transformation to ensure captioning data
does not get included in the transformed video. If parameter 18 Caption Xlator
is On, the copied caption gets translated into an HD caption and inserted into
the transformed output (and if the caption translator is Off, the output does not
contain caption data). This is the setting to use if the SD input includes a caption
and you want to retain it at the output (parameter 18 Caption Xlator must be On),
or you want to blank it at the output (18 Caption Xlator must be Off).
Pass
In Pass mode, the FS-HDR does not blank line 21 of the SD video input and passes
the unaltered video to the Video Processor for transformation. This is the setting
to use if there is no captioning data present on line 21 of a 525i video input.
Auto blank
In Auto Blank mode, the FS-HDR automatically detects presence or absence of
line 21 caption data on the SD input. If no line 21 caption is present, the FS-HDR
passes the video unaltered. If line 21 data is detected, the FS-HDR copies the data,
blanks line 21, and reinserts translated captioning on the transformed output if
