Word Explanation
GPI
[General Purpose Interface]
Interface signals which control auto transition from an external source.
Hue The color tone of the video signals.
IRE A unit used for video signal levels.
The setup level (black level) of the signals is expressed as 0 IRE, 7.5 IRE, etc.
Key Edge The border or shadow added to the edges of keys.
Key Fill The signal that uses key combination processing to fill in the areas left blank by the
key signals.
Key Gain A parameter which is used to adjust the amplitude of the key signals.
Key Invert A function which inverts the key signals.
Key Mask This is the function that specifies the area for key combination using the box pattern,
etc. When only part of the area of the key signals is used, key combination is
executed with the unnecessary area masked.
Key Source The video signals for creating the key signals.
Linear Key The function which combines keys using monochrome key signals with gradations in
its outlines as a reference.
Lum
[Luminance]
The brightness portion of the video signals.
Luminance Key The function which creates key signals based on the luminance (brightness)
information of the video signals to combine keys.
ME
[Mix Effect]
A video effect device which combines a number of video signals to create mix, wipe,
key and other video signals.
Mix The picture-changing effect produced by overlapping one image with the next.
It is also referred to as “dissolve”.
Multi View Display This function combines multiple materials and displays them on one screen. PGM,
PVW and the input material can be previewed at the same time on a single screen.
OSD [On Screen Display] This function enables settings to be performed on the menu screens which are
displayed in the monitor output.
PinP [Picture in Picture] This function combines a sub screen image with the background image.
PVW
[Preview]
The function for checking ahead of time the image which will be output after the next
transition. The image is output from the PVW system.
PGM
[Program Bus]
The bus which always carries the program output signals.
PST
[Preset Bus]
The bus which carries the program output signals after the next background
transition.
RS-422 A serial interface standard. It is the interface used to control the switcher from an
editor or other external device.
Sat
[Saturation]
This refers to the intensity of the color chrominance level of video signals.
SDI
[Serial Digital Interface]
The standard by which video signals in various SD and HD formats are transmitted
along a single coaxial cable.
Self Key A function that creates key signals from key fill signals for combining keys.
Setup Data The memory in which the control panel statuses can be saved and recalled.
The button selection statuses as well as the border, color and other setting
information can be saved in this memory.
