The following terms and definitions are used throughout this guide:
•
A “ Background ” is an unscaled source, typically originating from a computer.
PresentationPRO-II enables you to work with one background source 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 a background. Keys are typically used for
titles 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 PresentationPRO-II.
•
A “ Mixer ” is the electronic circuitry that enables you to transition (and scale) PIPs
and Keys over a background. PresentationPRO-II has one internal mixer, capable
of layering either one PIP or one key.
•
“ Operator ” refers to the person who uses the system.
•
“ PIP ” refers to Picture-in-Picture, an on-screen effect in which one “scaled” picture
(typically of reduced size) is positioned over a background image. PIPs can be
reduced, enlarged, bordered, shadowed, and mixed on and off Program.
•
“ Screen ” and “ Menu ” both refer to the Touch Screen menus.
•
“ System ” refers to the PresentationPRO-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).
