Glossary
DVI-I
DVI-I transfers digital and analog video in-
formation via one single interface. Thus, us-
ing a simple adapter, a VGA signal can be
derived from the DVI-I output.
E
Effect
A setup of panel controls specifying the
sources involved and any processing applied
to those sources. Effects can be learned
(saved) and recalled by the E-MEM effects
memory system.
Effect Transition
Recalling an E-MEM effect so that a transi-
tion is automatically performed at the start of
the recall.
Effects Processor
The portion of a switcher that performs mix-
es, wipes and cuts between background
and/or effects key video signals.
E-MEM Effects Memory
A feature that permits control panel setups to
be stored for later recall.
Ethernet
A form of high speed data transport between
devices on a network.
F
Fade to Black
A mix transition to black.
Fader
Straight-line slider for the audio level con-
trol.
Field
One scan of an interlaced video image. In in-
terlace systems, two fields are required to
make a complete picture (video frame) be-
cause alternate lines are scanned.
Fill Video
A video signal which fills a hole cut in back-
ground video by a key control signal.
Flip-Flop
A transition where the sources selected on
the background buses (for example, preset
and program) of an M/E are exchanged at
the end of a transition. The original preset
bus source becomes selected on the program
bus, and the original program bus source be-
comes selected on the preset bus.
Frame
One complete scan of a video image. For in-
terlace video, alternate lines are scanned, and
so a frame containing all the picture informa-
tion consists of two fields.
Frame Rate
The number of frames presented per second.
For interlace systems the frame rate is half
the field presentation rate.
G
Gain
An amplification factor applied to a key con-
trol signal by a keyer that determines how
much, if any, of the background and key fill
video will be mixed together at the key edge
areas. Low gain (1, or unity) generally results
in a linear key.
Also the amplification (boost) of an audio
signal, esp. useful with mic inputs.
GP (General Purpose Interface)
An interface that allows limited remote con-
trol of some of a device’s functions.
