3.6.4.3 Self/Couple Key Button / Split/Couple Key Button (Software V622 and higher)
When the Miscellaneous Bus is delegated to a keyer, a source selection always
selects the Fill signal for the according keyer.
The Self/Couple and Split/Couple buttons define the way in which the key signal is
selected.
If Self/Couple Key is selected, the selected Fill signal is also used as key signal.
If Split/Couple is active, a selection of the Fill signal does not change the key signal. To
select the Key signal, hold down the Split/Couple button and select the key source on
the Miscellaneous Bus.
NOTE! If you want to see in Split Key mode which source you have selected as key
source, press Split/Couple Key. The Key Buses row will indicate the source as long as
the button is held down.
If
both of the two buttons are active, the selection is done in coupled key mode.
In Coupled key selection mode, the operator selects a Key Fill source on the Key
Buses row and the switcher automatically selects the Key Source signal using the
Coupled Key table.
The Coupled Key table is defined in the menu.
The default table entry for Coupled Key is
White . For DVEs, character generators,
graphics, etc., the input where the Key signal from such an image source is connected
should be coupled to the input where the video signal is connected.
