3. Basic operations
3-6.  DSK (downstream key)
Characters or other images can be combined with the background image.
This unit supports two DSK channels.
3-6-1.   Selecting the DSK type

Press the [DSK1] button (or [DSK2] button) to light its indicator and display the DSK1 menu (or DSK2 
menu).
 Refer to “2-1-5. LCD menu area”.
 Turn [F1] to display the DSK1 sub menu (or DSK2 sub menu).

 Turn [F2] to select the Type item.
Lum (luminance key/self key):
  This is for creating the key signals from the luminance component of the key fill signal.
Linear (linear key/EXT key):
   This is for creating the key signals from the luminance component of the key source signal. 
It is used when the key source signal and key fill signal are different.
Since the luminance key is operated as a self key, the key fill signals are used as the key source signals. 
When the luminance key has been selected as the downstream key type, the key signals will remain 
unchanged even when the key source signals are switched.
When using the linear key, use material with a black background and white characters or shape to be 
combined by the key as the key source signal.
Material which is not black and white may not be combined clearly.
Material with a white background and black characters, etc. can be reversed using the key invert function for 
use.
 When the luminance key has been selected, the chroma components can be contained in the key signals 
generated in view of the fact that it is used as a self key. (This is not applied to the linear key.)Turn [F3] to 
select the setting using the LumKey item.
ChrmOn:   In addition to the luminance components, the chroma components are also factored in when 
generating the key signals.
Use this setting if colors with low luminance components are used for the key signals (when, 
for instance, blue characters are to be removed).
ChrmOff:  The key signals are generated only from the luminance components.
 Turn [F4] to select the fill type using the Fill item.
Bus:  The bus signal is used for the key fill signal.
Matte:  The internal fill matte is used for the key fill signal.

selected is now established for the AUX bus crosspoint buttons.
The selected AUX bus crosspoint button lights in amber. (It will light in red if the selected signal is a PGM output 
signal.)
