ScreenPRO-II • User's Guide
A "Background" is an unscaled source, typically originating from a computer.
ScreenPRO-II enables you to work with two background sources, each of which
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.
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 ScreenPRO-II.
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." ScreenPRO-II has one internal
M/E, capable of layering 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.
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).
