Appendix (glossary)
Defined below are the terms used in this manual.
Word | Explanation |
|
|
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 |
[Black burst] | reference signal for |
|
|
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] | |
|
|
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 |
|
|
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. |
