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 seamlessly transition (and scale) PIPs and Keys over a background.
MVR (Multiviewer)
A video output that previews sources, backgrounds, destinations and Auxiliaries in scaled down windows with
a border and a text label.
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).
PVW (Preview)
The video that will appear next on program (main) outputs.
RGB
The red, green and blue color signal components.
Scaler
An electronic circuit that reduces or enlarges source images, thus creating PIPs and Keys that can be
positioned (and transitioned).
SDI (Serial Digital Video)
SD / HD / 3G / 6G / 12-SDI is a digital representation of the video signal that is distributed via a single coaxial
cable with BNC connectors. (SMPTE 259M / 274M / 296M / 424M / 2082M). Example formats are 480i and
525i.
