User Manual
Effects
Processor The portion of a switcher that performs mixes, wipes and cuts between background and/or
effects key video signals.
E-MEM
Effects
Memory A feature that permits control panel setups to be stored for later recall.
Engineering
Setups On the GV Switcher system, a collection of configuration settings that establishes an
essential baseline for system operation and integrates the system into a facility.
Ethernet A form of high speed data transport between devices on a network.
Fade To Black A mix transition to black.
Field One scan of an interlaced video image. In interlace systems, two fields are required to make
a complete picture (video frame) because alternate lines are scanned.
Fill Video A video signal which fills a hole cut in background video by a key control signal.
Fixed Linear
Key A linear key that uses predetermined Clip and gain settings that are not adjustable.
Flip-Flop A transition where the sources selected on the background buses (for example, preset and
program) of an ME are exchanged at the end of a transition. The original preset bus source
becomes selected on the program bus, and the original program bus source becomes
selected on the preset bus.
FPGA Field Programmable Gate Array.
Frame One complete scan of a video image. For interlace video, alternate lines are scanned, and so
a frame containing all the picture information consists of two fields.
Frame Rate The number of frames presented per second. For interlace systems the frame rate is half the
field presentation rate.
Gain An amplification factor applied to a key control signal by a keyer that determines how much,
if any, of the background and key fill video will be mixed together at the key edge areas. Low
gain (1, or unity) generally results in a linear key.
General
Purpose
Interface
(GPI) An interface that allows limited remote control of some of a device’s functions.
House Sync Sync generated within a facility that is used as a reference for generating and/or timing other
signals.
Hue The location of a color on the color spectrum (i.e. red, yellow, green, blue). Chroma, hue, and
luminance make up the three characteristics of television color.
