Explanation

 

 

GPI

Interface signals which control auto transition from an external source.

[General Purpose Interface]

 

 

 

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

The brightness portion of the video signals.

[Luminance]

 

 

 

Luminance Key

The function which creates key signals based on the luminance (brightness) information

 

of the video signals to combine keys.

 

 

ME

A video effect device which combines a number of video signals to create mix, wipe, key

[Mix Effect]

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

The function for checking ahead of time the image which will be output after the next

[Preview]

transition. The image is output from the PVW system.

 

 

PGM

The bus which always carries the program output signals.

[Program Bus]

 

 

 

PST

The bus which carries the program output signals after the next background transition.

[Preset Bus]

 

 

 

RS-422

A serial interface standard. It is the interface used to control the switcher from an editor

 

or other external device.

 

 

Sat

This refers to the intensity of the color chrominance level of video signals.

[Saturation]

 

 

 

SDI

The standard by which video signals in various SD and HD formats are transmitted along

[Serial Digital Interface]

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.
