Terms and Definitions
qÉêãë=~åÇ=aÉÑáåáíáçåë
The following terms and definitions are used throughout this guide:
• A “Background” is an unscaled source, typically originating from a computer. A
background source appears at the system’s lowest priority — visually in back of all
other sources.
• The abbreviation “BG” is also used throughout this guide for Background.
• The term “Controller” is synonymous with ScreenPRO-II Controller.
• A “Key” is an electronic (and visual) process whereby one image is electronically
superimposed over another source or background. Keys are typically used for
titles, logos and banners.
• A “Layer” is 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.
• A “LOGO” is a full screen image that is selected from one of three still frames that
you can capture with each individual ScreenPRO-II unit. A maximum of 12 still
frames can therefore be controlled from the ScreenPRO-II Controller.
• A “Mixer” is the electronic circuitry that enables you to transition (and scale) PIPs
and Keys over a background.
• “M/E” (Mix/Effects) is synonymous with “mixer.” Each individual ScreenPRO-II
has one internal M/E that can layer either two PIPs, two keys, or one of each.
• “Operator” refers to the person who uses the system.
• “PIP” refers to Picture-in-Picture, an on-screen setup 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.
• “Screen” and “Menu” both refer to the Touch Screen menus.
• “System” refers to the ScreenPRO-II Controller and its associated individual
ScreenPRO-II units.
• A “Scaler” is the electronic circuitry that enables you to reduce or enlarge source
images, thus creating PIPs and Keys that can be positioned (and transitioned).
