Dsk Function - Datavideo HS-2200 Quick Start Manual

DSK Function

The HS-2200 has two Down Stream Keys (DSK PGM, DSK PVW). This means it is able to take a key source video
input and replace the white or black parts of this image with the video from another source. If the input video carries
an alpha channel it is also possible to key in this way too.
