Use the Video Proc web page (
) to adjust the composite
output of each channel. Select the channel to be adjusted from the
Channel 1 – 4
buttons.
Make the following video processing adjustments on this web page:
•
Enable a color bars test signal to the channel output by selecting the
Color Bars
radio button in the Test Signal Generator control.
Select the
Disable
button for normal operation.
•
Check the
Chroma Kill
checkbox to shut off chroma for a black and white
picture on the channel output.
•
Set the amount of Black Clip level with one of the radio buttons. Select
None
for no black clipping.
•
Turn Burst off or on (default) by checking or unchecking the
Burst
checkbox.
The Video Processing section provides the following controls:
•
Contrast/Y Gain – adjusts the percentage of luminance relative to
white.
•
Saturation/Chroma Gain – adjust the percentage of saturation and
chroma gain relative to 100% saturation.
•
Brightness/Y Offset – adjusts amount of brightness/Y offset in percent.
•
Hue/Chroma Phase – adjust hue/chroma phase in degrees for both
line rates.
Note
The Contrast Y Gain control interacts with the Brightness/Y Offset control.
Adjusting the former will affect the latter in order to maintain optimum per-
formance and range. This is normal operation and part of the design of these
controls.
