3. General
Key Fill
The video which fills the hole cut by the keying circuitry. Typically, switchers provide a variety of choices for the fill source — internal
mattes, external video, or "self" fill are several examples.
Key Mask
A key modification system that protects a portion of the foreground video from being keyed, using the switcher's internal pattern
system.
Key Signal
Also known as Key Source. The signal that electronically cuts the hole in the background video signal. Key signals typically originate
from external inputs such as character generators or cameras.
Layer
An image display element (such as a PIP, Key or Background) that has an associated visual priority — either in front (or in back) of
another layer.
Linear Key
Linear key is a keying mode in which the edges of anti-aliased key sources (such as character generators) are reproduced clearly.
Typically, two separate signals are required from a linear key source: a cut and a fill.
Menu
A term used to describe buttons and functions on the high-resolution color LCD touch screen.
Mix
Also known as a Dissolve. A transition between two video sources in which one source fades out as the other fades in.
Mixer
Circuitry that enables you to transition (and scale) PIPs and Keys over a background.
Multiviewer (MVR)
MVR is a monitoring system that enables multiple sources (input and outputs) to be displayed on one or more monitors, eliminating
the need for individual source monitors. By utilizing different arrays of PIPs, users can select the preferred multiviewer "look," and
streamline their workflow.
NTSC
National Television Standards Committee. The oldest standard for color picture broadcasting. NTSC is a standard definition format
that operates at a frequency of 60Hz, with 525 lines, 60 fields and 30 frames per second.
PAL
Phase Alternating Line. PAL is the NTSC equivalent TV standard in Europe. PAL is a standard definition format that operates at a
frequency of 50Hz, with 625 lines, 50 fields, and 25 frames per second.
PGM (Program)
The switcher's main output signal.
PIP
Picture-in-Picture, an on-screen configuration in which one picture (typically of reduced size) is positioned over another background
image — or another PIP. PIPs can be reduced, enlarged, bordered, shadowed, and mixed on and off Program. PIPs can overlap
each other, depending on their visual priority. In E2, the multiviewer PIPs are not allowed to overlap.
Preset
Storage register in which you can store (and recall) the entire configuration or "look" of your destination(s).
PRVW (Preview)
The video that will appear next on program (main) outputs.
RGB
The red, green and blue color signal components.
RGBHV
Defines a connection scheme with five lines: one for red, one for green, one for blue, one for the horizontal sync and one for the
vertical sync. This is the standard used in VGA and other analog PC computer monitors.
