Internal Dsk; External Dsk - Datavideo SE-900 Instruction Manual

Internal DSK

With Internal DSK the SE-900 does the keying internally, removing the background from the CG input. The
levels can be set to remove black levels or white levels according to the graphic you are working with.

External DSK

External DSK relies on an external card, such as a Black magic Design Card, to overlay the graphics and
return the signal to the SE-900.
