Panasonic AW-HS50N General Purpose Interface Hue, Key Edge, Key Fill, Key Gain, Key Invert, Lum

Appendix (glossary)

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,
[Mix Effect]	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]	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
[Preset Bus]	transition.
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
[Serial Digital Interface]	along 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.
