The Y Key invert changes the keying characteristics with respect to what colors of
the foreground image you wish to ‘key out’.
Setting it to Off will cause the colour range that’s defined to be removed - remove the
desired colors. Setting it to On will cause the colour range that’s defined to be kept -
key out all other colors.
The descriptions above behave identically on the remaining U Key Invert & V Key
Invert component versions. However they are directed at the U/B-Y (blue) colour
component and V/R-Y (red) colour components respectively. Adjustment and effects
are the same as explained above for Y Key Invert (brightness/grey-scale).
8.6 Items Associated with the Adjust sources group
The ‘Adjust Sources’ menu group accesses the parameters associated with the
processing amplifiers used for each input (RGB, CV, YC, etc.). They allow you to
fine-tune an incoming signal to optimize its color, brightness or even sharpness.
Not all settings are available for all input types, and not all input types listed here
may be available on your unit.
It is recommended that you Store your settings once you’re happy with them in
readiness for future use.
This menu item selects the input connection for which you want to make adjustments
to. As in the image above, changes will only be made to the source connected to
RGB1. Once the selection has been made, all changes made using the following
operating parameters will only apply to the selected input.
Selection of a CV/YC source will reveal different menu items that
allow adjustments beyond those used for RGB sources. The
menu discussions that follow relate first to RGB sources, then to
CV / YC type sources.
8.6.1 Menu items common to all inputs
This menu item allows manual positioning of the Top and Left portion of the image.
It is used to ensure that the input signal is captured correctly, eliminating any black
borders. These settings are often used to correct the position of a PC signal on an
input, or to eliminate any undesired noise at the top or bottom of a PAL or NTSC
video source.
