Background (BG)
An Event Master processor can use any still store or matte and assign it as a Background source, provided it
is at the same resolution as is the destination. The Background appears at the system
’ s lowest layer priority
and does not use any system scaler resources.
Chroma Key
A type of key where the hole-cutting information is derived from a color rather than from a video level. An
common example on television, is when the weatherman appears to be standing in front of a map. The map
itself is a video signal, and the weatherman is in fact standing in front of a green (or blue) screen. On the
switcher, the Chroma Key process electronically subtracts the color from the foreground image, and replaces
it with video from the background image to form a composite image.
Clip, Gain, Opacity
In switcher terminology, the process of fine-tuning a key of any type (luminance, linear, or chroma). Clipping
sets the threshold for the hole cutting circuitry, while "gain" defines the range and sensitivity of adjustment.
The "opacity" is the transparency or density of the key, as revealed over a background.
Colorspace
All video signals have a colorspace. Versions are RGB, YUV or YrYbYc. They also have a range like 16 -240 =
Reduced or Full 0-254.
There is also a color processing scheme that allow bandwidth saving. Full would be 4:4:4 and versions include
4:2:2 and 4:2:0
Computer Video
A generic term indicating video that originates from a computer platform. A progressive scan signal that
follows VESA (Video Electronics Standards Association) standards, with typical resolutions of 800 x 600, 1920
x 1080, UHD and 4K etc.
Crosspoint
Traditionally the button that selects the input required on a particular switcher bus. But in Event Master device
the actual backbone of the processors who routes the internal video signals.
Cut
Cut is an instantaneous switch from one video source to another.
DA (Distribution Amplifier)
A video device that inputs one video signal, and outputs multiple “ identical ” signals.
Destination (DST)
A Destination is a location to which you can route the output of an Event Master device. A destination can be
configured as a group of one or more outputs that feed the same screen.
A Destination can be a single, widescreen or multi-screen Mixing Layers are assigned to Destinations.
A Destination can transition Backgrounds and Mixing Layers.
Event Master Control Software (EM GUI – EMTS)
This user's guide refers to the Event Master control software as the EM GUI (version 6.4) or as the EMTS
(Event Master Toolset Software). The software consists of several menus and tabs that enable you to
configure your system, setup the input sources and output Destinations, manage the dedicated Multiviewer
and create your presentation
’ s overall “ look. ” Refer to the chapter . “ EM GUI orientation ” , page 65 for more
information about the EM GUI.
Event Master Series Processor (EMP)
Any Event Master E2 Lite processor may be referred to as an EMP.
