3. TERMS AND DEFINITIONS
LAYER: a “layer” is an image display element that has a visual priority.
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. A PIP is considered as a layer.
FRAME: a “frame” is a full screen image which is selected from one of the still frames you can capture. A
frame can be captured in flash memory from any video or computer source plugged into the machine.
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 Chroma Key, and removing content based on
its brightness or luminance levels is called a (Luma Key). Keys are typically used for titles, logos and special
effects.
QuickMatriX
allows you to key a live source (such as a camera shot with green or blue background,
or a title with a black background) over any other source or sources.
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.
RCS²: Remote Control Software used to control, set up, and operate the device.
QUICK FRAME: The “Quick Frame” feature allows the instant display of a stored frame above all layers.
