Video Processor Description
Note: Unless otherwise noted, the following functions are independently available
for Path 1 thru Path 4 processing paths.
The 9926-xHtoS video subsystem provides the functions described below.
Input Video Select Functions
Used in common as a routing source for
Path 1
thru
Path 4
is a GUI-based
control that allows the card to select from up to four HDMI inputs to be used
as four sources for
Path 1
thru
Path 4
processed video paths.
Additionally for each path, Source Colorimetry can be independently set for
used as marked, or set for BT.709 or BT.2020. Also for each path, Source
OETF can be independently set for used as marked, or set for SDR, PQ/ST
2084, or HLG.
Frame Sync Function
This function provides for frame sync control using either one of two external
FRAME REF IN (1,2)
reference signals distributed with the card frame, selected
input video, or internal timing as a frame sync reference.
This function also independently allows horizontal and/or vertical offset to be
added between the output video and the frame sync reference for any of the
up to card’s four processed video paths.
Frame sync can select from either of two card frame reference sources, or
free-run input video sync. Selectable failover allows alternate reference
selection should the initial reference source become unavailable or invalid. In
the event of input video loss of signal, the output can be set to disable video,
go to an internal flat-field generator, or freeze to the last intact frame (last
frame having valid SAV and EAV codes).
Color Corrector
Option
+COLOR
converts the YCbCr SDI input video to the 4:4:4 RGB color
space (where the color correction is applied), and then back to YCbCr SDI on
the output. Controls are available to adjust each RGB level independently for
both white levels (gain) and black levels (offset). Gamma can also be
independently adjusted for each RGB channels. Various controls can be
ganged to provide adjustment for all three color channels simultaneously.
Color Correction allows custom independent user settings for each of the up
to four processing paths.
