3. TERMS AND DEFINITIONS
BACKGROUND: a “Background” is a source, typically originating from a computer. Ascender 32 enables you
to work with live or still (Frame) background sources — visually in back of all other sources.
LAYER: a “Layer” is an image display element (such as a PIP window, Key, Logo or Background) that has a
visual priority — either in front (or in back) of another layer. Up to 4 independent true-seamless scaled layers
are available on the Ascender 32.
PIP: a “PIP” (Picture In Picture) is a picture, typically of reduced size, which is positioned over another
background image or other PIPs. PIPs can be repositioned, reduced, enlarged and displayed with borders.
PIPs can overlap, depending on their visual priority. Ascender 32 offer various slides, wipes, and fades for
dynamic PIP entrances and exits. A “flying” PIP is also possible using vertical, horizontal, diagonal, or curved
movement. A PIP is considered a layer.
FRAME: a “Frame” is a full screen image which is selected from one of the still Frames you can capture or load
to the Ascender 32. A Frame can be flash captured and imported from any video or computer source plugged
into the machine. It can also be loaded to the device from a USB key.
LOGO: a “Logo” is a part of a screen image that can be flash captured and imported from any video or
computer source, by keying or image cut-out. A Logo can be positioned anywhere on the screen. Ascender 32
can also resize the logo to be displayed in any size on the screen. An animated logo is also available.
KEYING: “Key” is an electronic process whereby a video image is electronically superimposed over another
source or background, by dynamically removing a portion of the first image. For example, removing all content
of a certain color (such as green or blue) is called a cutting out either a color (Chroma Key,) and removing
content based onor its brightness or luminance levels is called a (Luma Key). Keys are typically used for titles,
Logos and special effects. Ascender 32 allows you to key use a live source with Luma or Chroma key effects
with green or blue background and to display key it over any other source or sources.
SCREEN: A “Screen” is a destination where the picture will be displayed. For example, it could be a single
display or a projection surface or which can be composed of one or several outputs. Each screen might be
used to composed with one or several layers.
SEAMLESS: Clean transition with no glitch or loss of sync while switching between two sources. For example,
fading through black to another source is a seamless transition.
TRUE SEAMLESS: Clean seamless transitions with no glitch or freeze between two sources. For example,
crossfading from source to source is a true seamless transition.
WEB RCS: Web browser based Remote Control Software used to control, set up, and operate the device.
SOFT EDGE: Soft Edge blending technology is used to compensate for the overlap or covering area when two
(or more) video projectors are combined to display a continuous content across one screen. The resulting
image will appear as though it were a single unified picture.
HARD EDGE: Hard Edge technology is used to display continuous content using to several outputs without
any overlap or covering area. The outputs are “side by side”, they don’t overlap or share pixel information.
(Opposed to Soft Edge where some parts of the image are simultaneously on several displays.)
CONFIDENCE MONITOR: Confidence monitoring consists on using an output to display a specific content
such as another screen, input or combination there-of. You can display one of the main outputs or Preview
output content. For example, you might use the confidence monitor to show both the presenter’s laptop
input as well as the Program screen on a single display.
