Video and Key Signal Paths
This discussion is an overview of the video and key signal flow paths, which will
help you better understand how DVEOUS works. It includes details of your
options for channel configurations, which is followed by block diagrams that
show the system video and key signal paths in more detail.
Channel Configurations
The standard DVEOUS is a twin channel system. It has one channel dedicated
for video (A) and a second channel (B). Both transformation paths are full-
bandwidth video channels. However, the B channel can process a key or drop
shadow signal instead of video. This gives DVEOUS three modes of operation.
Video+Video
This mode lets you use the B channel as a video channel. This channel has inde-
pendent control of all keyframe parameters including motion paths, warps, light
sources, and textures. The DVE processor internally generates the key signals
associated with these signals. Each channel's key signals are raster size “white”
with adjustable opacity and edge softness.
