3.4 Terms and definitions
3G
A 3 Gbit/s serial digital 10-bit or 12-bit video interface (SMP TE 424 M and 425M).
AUX (auxiliary Output)
A video output that can show any source and seamlessly cut between them.
Background (BG)
Typically an unscaled source originating from a computer ’s multi-head graphics card, or a fram e grab from a scaled sour ce. An
Event Master processor c an use any input signal and assign it as a Background source, provided it is at the same r esolution as is
the destination. The Background appe ars at the system’s lowest layer priority and does not use any syst
em 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 ex ample on
television, is when the weatherman appears to be s tanding in front of a m ap. 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 co lor
from the foreground image, and replaces it with v ideo from the background image to form a composite image.
Clip, Gain, Opacity
In sw itcher terminology, the p rocess of fi ne-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 sens itivity of adjustmen t. T he "opacity" is the transparency or density of
the key, as rev ealed over a background.
Colorspace
All video signals have a colorspace. Versions are R GB, YUV or YrYb Yc. They also have a range like 16 -240 = Re duced 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 p latform. A progressive scan s ignal that follows VESA (Video Elec -
tronics Standards A sso ciation) 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 s witcher bus. But in E vent Mas ter device the actual backbone
of the processors w ho routes the internal video signals.
Cut
Cut is an instantaneous switch from one video source to another.
DA (Dis tribution Amplifier)
A video device that inputs one video signal, and out
puts multiple “identical” signals.
Destination (DST)
A Destination is a location to which you can route the output of an Event Mas ter device. A des tination can be co nfigured as a gr oup
of one or more outputs that feed the same screen.
A Destination can be a single, widescreen or multi-screen M ixing Layers are ass igned to Destinations.
A Destination can transition Backgrounds and Mixing Lay ers.
Event Master Control Software (EM GUI)
This user ’s guide refers to the Event Maste
r control software as the EM GU I. The s oftware consists of s everal 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 87 for more information abo ut the EM GUI.
Event Master Series Processor (EMP)
Any Event Mas ter series processor—E 2, E2 Jr., S3–4K, S3–4K Jr., or EX— ma y be referred to as an EM P.
Event Master Toolset Software (EMTS)
Event Master Toolset S oftware is an easy to us e G UI running on a PC or MAC . It provides all the Even t Master series processors
with control and configuration.
