Word | 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 |
| 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] |
|
|
|
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. |
