Functional Description
The Effects Send outputs can also be directed to the Frame Store
option for image capture. One optional Effects Loop Crosspoint
module services all three Mix/Effects banks.
Each M/E has two keyers and two background buses (A and B) as
inputs. In standard mode, Keyers 1 and 2 can be mixed into a
composite video and key which can be forwarded to the DSK, the
other M/E, or output. In layered mode, Backgrounds A and B are
also used as keyers that operate in a manner similar to Keyers 1
and 2.
Optional preview capability allows monitoring of sources at
certain points in the signal flow. You can preview video from the
M/E mixers, Flip/Flop Mix and DSK mixer, switched preview
bus, or mask bus.
Eight pulse- or level-sensitive GPI inputs are provided. You can
assign each of these inputs via the GPI Input menu to perform a
specific function when triggered.
The editor interface consists of an asynchronous RS-422, 38.4K
baud serial communications port, managed by a communications
processor.
