Functional Description
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,
another 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 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.
