The Video Proc web page (
) provides access to pro-
cessing amplifier controls for each channel. Refer to
a summary of controls, defaults, parameter ranges and what lines of video
are affected by each control.
Select the channel to be adjusted from the
Channel 1 – 4
buttons.
Configure the following for each channel:
•
Video Processing – enable or disable video processing for the channel
or select a test signal (100% Color Bars or Pathological).
Note
Test signals are not adjustable with the video processing controls. The video
processing controls can be changed while using the test signals but will have
no affect on the test signal output.
•
Chroma Kill – select this checkbox to shut off chroma on the channel
output. This control will also affect the VBI lines.
If the channel is assigned as a monochrome signal (see
), the Chroma Kill function will be forced to a
. If the monochrome
status is turned off, the checkbox will return to its previous state.
When the
Enable
button is checked in the Video Processing section, the fol-
lowing controls will be active:
•
Contrast/Y Gain – adjusts the percentage of luminance relative to
white.
•
Saturation/Chroma Gain – when ACC is enabled on the Video Com-
posite In web page, adjust the percentage of saturation and chroma
gain relative to 100% saturation. When ACC is disabled (the default),
this control will be a read-only value (100%).
•
Brightness/Y Offset – adjusts amount of brightness/Y offset in mV.
•
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.
