Chroma Keyer Subpanel
The basic Chroma Keyer option consists of a Chroma Key Carrier
Module for each M/E, providing two chroma keyers per M/E.
With this option installed, a chroma key may be done using any
4:2:2 crosspoint signal on the M/E key bus as a source. For
external component video sources, an optional dual Chroma Key
Input Module can be added, this provides two component video
sources.
With a Chroma Keyer option installed in one or both M/Es, the
Model 2200 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 2-6)
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. These are described here and in the menu
descriptions under Chroma Key Menu on page 3-65
