In UpConvert or SD Aspect Ratio Convert modes, this setting blanks input video

Passes input video Line 21 to the converter and to the outputs.
The FS1 looks for Line 21 caption data on the video input. If present, Line 21 is
blanked before video conversion occurs. If no caption data is found, Line 21 passes
to the converter.
