Section 1: Introduction to Dveous/MX
The twelve video signals, the SuperMatte generator, the Pattern Framestore,
and the Defocus outputs are all available as DVE/texture matrix outputs. The
nine matrix outputs feed two video/key sources (A and B) and two texture
sources (A and B) to the transform boards, as well as to the background. Note
that you can use any source anywhere, and in more than one place.

The DVE video/key sources feed the reTouch Color Corrector function. The
™
Color Corrector output supplies the transform boards' input. The transform
boards use the texture signals to modify the light source generator.

DVE Paths
As previously discussed, you can configure the DVE in three modes:
Video+Video, Video+Key, and Video-Key+Shadow. This discussion includes a

drawing for each mode.
Video+Video Mode In the Video+Video mode, the transform boards process
the video in identical paths. It applies the texture input to the light source gen-
erator, then combines that output with the video input.
There are two transform controllers: one is dedicated to the A input, the other
to the B input. Each transform controller generates an edge key signal that
defines the transformed raster edges. The transformed outputs are then com-
bined into a single video and key output and sent to the Combiner for output
processing. The combining process uses either a fixed priority (A over B or B
over A) or a Z based priority, where each image's position in 3D space deter-
mines the priority. The graphics output has axis cursors for the A and B chan-
nels.
