Keyer Controls and Operation
Key modifiers are available to add borders whose luminance parameter
can be adjusted. The clip and gain key parameters can be set and are used
in conjunction with the optional Chroma Keyer (SD only).
SqueezeBack, a special type of key, is offered as an option on the M–2100
for both SD and HD systems.
Note All video sources to the M–2100, including primary video and key inputs,
must be timed within +/– 1/2 line (+1/4, –3/4 for HD) relative to the reference
input to be synchronous.
SD Systems
Keys are installed in pairs — you can have 2 or 4. Each keyer module can
contain 2 Linear Keyers, or 1 Chroma Keyer and 1 Linear Keyer. Modules
can be installed in either or both of slots 5 and 6 of the A/V/C Processor
Frame. Chroma Keyers (if present) are controlled by
Key Select buttons 1
and/or 3.
HD Systems
HD systems can be configured with the same Linear Keyers modules as the
SD systems, or a combination of Framestore and Single Luminance/Linear
Keyer module(s) and Linear Keyer module(s). Modules can be installed in
either or both of slots 6 and 7 of the A/V/C Processor Frame.
Note The M–2100 HD system does not have Chroma Key, Borderline, or Drop
Shadow capability.
