Chapter 5 Basic Operations — USK (Upstream key)
USK (Upstream key)
Combine characters or other images with the input image in the input area.
Key sources generated using the four USK lines can be handled as sources with a telop without using ME by combining them with input images.
In addition, a 4:3 source of SD can be handled as a source by placing CG sources on both of its wings.

Selecting the USK type
Set the key type on the Menu Panel AV-HS60C3.
1
Select the <DSK MISC> button → [USK] → [USK1] to [USK4] tabs.
2
Select an item in [Type] in the [USK] column.
f
Select the method to generate key signals. The selection status is stored for each source material.
[Lum]
(luminance key/self key)
Creates key signals from luminance components or luminance and chrome components of key fill signals.
f
Since the luminance key is operated as a self key, the key fill signals are used as the key source signals.
The key signals do not change even when the key source signals are switched.
[Linear]
(linear key)
Creates key signals from luminance components of key source signals.
It is used when the key source signal and key fill signal are different.
f
Use source with a black background and white characters or shape to be combined by the key as the key source
signal. Source which is not black and white may not be combined clearly. Source with white background and black
characters can be used by inverting the keys with the key invert function.
[Full]
(full key/self key)
Creates key signals using the images on the full screen as the key source signals.
f
The key signals do not change even when the key source signals are switched.
3
Select an item in [Lum Key] in the [USK] column.
[Chroma Off] Generates the key signals only from the luminance components.
[Chroma On]
Generates the key signals considering the chrome components in addition to the luminance components. This item is set
when a low luminance component color is used for key signals such as when cutting blue characters.
4
Select an item in [Clean Key] in the [USK] column.
[Off] Cuts key fill with a key signal.
[On]
Does not cut key fill with a key signal. The part of key fill not cut out with the key signal is superimposed on the
background image.
