FS4 Frame Synchronizer/Converter v1.1
3 SD Line 21
Blanking
This parameter determines whether the FS4 blanks line 21 closed captioning data prior
to video processing of an SD 525i video input. (Line 21 normally occurs at the top of the
raster in the overscan area of video, so the presence of captioning data or blanking does
not interfere with the visible SD or Upconverted video.).I
Blank
In Blank mode, the FS4 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 FS4 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 FS4 automatically detects presence or absence of line 21 caption
data on the SD input. If no line 21 caption is present, the FS4 passes the video unaltered.
If line 21 data is detected, the FS4 copies the data, blanks line 21, and reinserts translated
captioning on the transformed output if parameter 18 Caption Xlator is On. If the Caption
Translator is Off, the output will not contain captioning. This is the setting to use if your
SD input video sometimes contains captions and other times does not, or if you are
uncertain which setting to use

In Four Channel Mode, the settings in this menu group apply only to the selected Video

1.1 Proc Amp Gain
This parameter adjusts the video gain from 0 to 1.5 times luma in 0.01 steps
Blank (default)
This setting copies caption data and blanks 525i input video Line 21
caption data before conversion, and may or may not include that
data (see above).
Pass
Passes input video unaltered to the converter and to the outputs.
Auto blank
Automatically detects caption data on SD input, passing unaltered
video if no line 21 caption is present, and reinserting caption data
if 18 Caption Xlator is On.
Off
(default)
On
Sets the YUV Proc Amp to Off.
Sets the YUV Proc Amp to On.
Variable
Adjusts Proc Amp Gain from zero to 1.5 in 0.01 steps.
