Terms and Definitions

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).
