Explanation

 

 

Frame Memory

A memory which can hold the video signals equivalent to one frame.

 

 

Frame Synchronizer

A function which matches the synchronization of non-synchronized video

 

input signals.

 

 

Freeze

A function which continues the display of the same image, creating the

 

impression that the image has been “frozen”.

 

 

FTB [Fade to Black]

This is the effect where the background image is faded out to the black

 

screen.

 

 

Genlock

A function for synchronizing the video signals using an external sync signal

 

as the reference.

 

 

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 Effect]

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]
