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 up-converted video.)
Blank (default)
Pass
Auto blank
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).
Passes input video unaltered to the converter and to the outputs.
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.
Blank
In Blank mode, the FS3 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 FS3 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 FS3 automatically detects presence or absence of line 21
caption data on the SD input. If no line 21 caption is present, the FS3 passes the
video unaltered. If line 21 data is detected, the FS3 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.
21 Test Pattern
This parameter selects the video source for the Test Pattern Generator. The
pattern generator is turned off and on using Output parameter
.
75% Bars (default)
Ramp
Flat Field
Black
100% Bars
Sets the test pattern to 75% bars.
Sets the test pattern to ramp.
Sets the test pattern to flat field chroma.
Sets the test pattern to black.
Sets the test pattern to 100% bars.
22 Freeze Output
This parameter tells the FS3 to freeze the current video frame on all outputs. This
may be useful either for testing or in case of loss of the input source.
Off (default)
On
Normal operation. The FS3 outputs video from the input.
The FS3 captures and freezes the most current video frame and
displays it on the outputs as long as this parameter is set to On.
The freeze feature can be controlled not only by the front-panel and web
browser interface, but also by a GPI input. When a GPI input is causing the freeze
condition, the EXT lamp will be lit on the front-panel.
