Appendix (glossary)

Defined below are the terms used in this manual.

WordExplanation

 

 

AB Bus system

A bus control mode. By executing a transition, the A bus and B bus signals are output to

 

the program images alternately.

 

 

Ancillary Data

The auxiliary data other than the video signals which is transmitted inside the data

 

stream of the video serial interface. The data superimposed on the vertical blanking

 

period is referred to as the V ancillary data (VANC).

 

 

Aspect ratio

The ratio between the horizontal and vertical dimensions of an image or screen.

 

It is 16:9 for the HD format and 4:3 for the SD format.

 

 

AUX

A spare bus which can be switched by signals other than the main line output signals.

[Auxiliary Bus]

 

 

 

AVDL

A function to automatically adjust the input image signal phase to the horizontal

[Automatic Video Delay Line]

synchronization reference signal phase.

 

 

BB

The black burst signal. A full-screen black level composite signal which is used as the

[Black burst]

reference signal for gen-lock.

 

 

Border

The area or margin that is added to the edge of a wipe or key.

 

Its width and color can be adjusted. The defocusing of the area around a border is

 

referred to as the soft effect.

 

 

Chroma key

This refers to the function for creating the key signals based on the color information of

 

the video signals and combining the keys.

 

 

Clip

The threshold level of the luminance when key signals are created from a key source.

 

 

Color Background

The signals which are output from the internal color generator and used as the

 

background image.

 

 

Cut

This refers to the effect where the display is instantly switched to the next image.

 

 

Density

A parameter which is used to adjust the density of the key signals.

 

 

Dot by Dot

This treats images as actual size (1) images. With PinP, it allows SD images to be

 

combined with HD images with no accompanying deterioration in the images themselves.

 

 

Down Converter

This is the function that converts material in the HD format into the SD format.

 

 

DSK [Downstream Key]

This refers to the key combination process which is performed at the end of the mix

 

effect. The key is always combined with the foremost image.

 

 

DVE [Digital Video Effect]

This refers to the transition patterns accompanying size reductions or slide effects.

 

 

DVI

A digital video interface standard.

[Digital Visual Interface]

DVI-I can handle both digital signals and analog signals.

 

 

Embedded Audio

This refers to the audio data packets which are transferred inside the data stream of the

 

video serial interface.

 

 

Flip Flop system

A bus control mode. The signals selected by the program bus are always output as the

(PGM/PST system)

program images. By executing a transition, the program bus and preset bus signals are

 

switched over.

 

 

Flying Key

This function uses DVE effects to move, expand or reduce key signals.

 

 

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.
