Video Processing
Proc Amp Functions
Each of the two output channels has an associated video proc amp which provides user
adjustable
Gain

Black Level
and
Hue
using on screen sliders.
Aperture Correction
An adjustable horizontal aperture corrector is provided for each of the two output
channels. This can be used to add (or remove) image sharpness as required.
Note. When using the down converter the filtering process results in a very slight
loss of high frequency information (which is normal), the aperture corrector can
be used to compensate for this slight loss.
Test Patterns
Each of the two output channels has its own independent test pattern generator which
provides a wide selection of test patterns which can be switched into each output.
(The
Test pattern will follow the selected output standard selected for each channel).
The selected test pattern is also available as one of the modes the synchronizer will
switch to when excessive video TRS errors are encountered. Possible synchronizer
actions when the input video errors become excessive are:
•
Freeze Field 1
•
Freeze Field 2
•
Freeze Frame
•
Selected Test Pattern
•
Black
Programmable Video Delay (optional: OC-5610-VDLY)
Each of the two SDI outputs has separate programmable video delays which can be set
(independently) between 0 and 12 frames (max). The adjustment is available in pixel, line
and full frame increments.
Note
The ARC (including the OC-5610-UPXD option, if installed) has fixed frame
delays depending on the signal path and selected function (see below). The 0 >
12 frame user adjustment is additional delay relative to the fixed delays.
This adjustment will delay the video output relative to the connected reference by the
delay setting specified. (+ fixed delay)
