FS1-X v1.1

78
The FS1-X Downconverters automatically intercept and reformat the SD caption data in
the incoming CEA-708 VANC packets, and output it on line 21 of the standard definition
outputs.
Input Scan and PSF
This parameter determines how the Deinterlacer handles interlaced vs. PsF inputs.
Normally, this control will only be used to indicate that a 1080PsF25 input is PsF and not
interlaced.
Auto
When Auto is selected, the system will look for clues in the source's SMPTE 352 (Payload
ID) data and respond accordingly. If there is no SMPTE 352 information, the system will
assume that 23.98/24 fps sources are PsF, and 25/29.97/30 fps sources are interlaced.
Progressive
When Progressive is selected, the system will assume that all sources are PsF (even if
there is SMPTE 352 data to the contrary).
Interlaced
When Interlaced is selected, the system will assume that all sources are interlaced (even if
there is SMPTE 352 data to the contrary)

SD Line 21Closed
Caption Blanking
This parameter determines whether the FS1-X 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.)
20 SD Line 21 Blanking
Blank
In Blank mode, the FS1-X 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 the output video is SD 525i, the copied caption
information gets reinserted on line 21 of the output. If the output video is Upconverted
and 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
HD 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 FS1-X 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 FS1-X automatically detects presence or absence of line 21
caption data on the SD input. If no line 21 caption is present, the FS1-X passes the video
unaltered. If line 21 data is detected, the FS1-X copies the data, blanks line 21, and
reinserts translated captioning on the transformed HD output if parameter 18 Caption
Auto (default)
Deinterlacer detects input source payload ID data and sets the
processing format accordingly.
Progressive
Assumes all input sources are progressive.
Interlaced
Assumes all input sources are interlaced.
