3.21.2 VIDEO ARCHITECTURE
The DD35 internal DVx (DVE) offers a high flexibility in the way it can be controlled.
You can control it in the same way you control existing DVEs, that means you can
combine up to 4 channels via a combiner and feed it into the switcher via a video
and a key input. That means you can combine up to 4 channels via the combiner
and the Video and Key are internally supplied to the input bus.
It is also possible to break down the architecture into two 2–channel DVxs each with
a video and key signal. Both DVxs can be controlled independently.
Each of the 2–channel DVxs can further be split into two 1–channel DVxs. In this
case the input into the switcher is superblack.
So up to 4 individual DVxs can be controlled independently for e.g. background–
or key–transitions.
DVx architecture can differ per DVx effect.
