Keyer Control Commands
Set Self Key, Separate Key, or No Key C
Oxtel series products implement keying where the Key is contained in the
luminance content of the SDI signal. The Key source is selected from either
the Fill input (known as Self Key) or a separate Key signal.
Self key sets the key input associated to a particular keyer layer to be derived
from the luminance content (Y value) of the “Fill” signal itself.
Separate key sets the key input associated with a particular keyer layer to be
derived from the luminance content (Y value) of the separate “Key” signal.
No key causes the key input associated with a particular keyer layer to be
ignored. The entire fill becomes visible without transparency.
Note: In swap-preview mode this value is associated with the preview
store. The value will remain with the image as it is stored or
transferred to the program channel.
