Chroma Keyer Subpanel
The Chroma Keyer option, which consists of a dual Chroma Key
input module and a dual Chroma Keyer (processor) module, adds
two Chroma Keyers to an M/E.
With a Chroma Keyer option installed in one or more M/Es, the
Model 3000 switcher can generate key signals on the basis of color
information contained in a video picture. User control of chroma
keying is provided by the Chroma Keyers subpanel (Figure 2-11)
and the CLIP and GAIN controls on the Keyer subpanel.
In addition to the controls provided on the Chroma Keyers
subpanel, several Chroma Keyer controls are provided via the
Menu Display.
