BORDERLINE Key Edge Generation
BORDERLINE® Key Edge Generators are optional for each keyer in the switcher.
The BORDERLINE option is added by plugging a small sub-module onto the
Keyer module of an M/E or the DSK. One sub-module can be installed for each of
the two keyers in each M/E and one in each of the two keyers of the Down Stream
Keyer (DSK) module. The Switcher could have up to six sub-modules installed,
two for the keyers in each M/E and two for the DownStream Keyer.
Each BORDERLINE Key Edge Generator supports 1, 2, or 3 line wide borders or
outlines. Video fill is provided within the borders. Shadow and extrude modes
create 1 to 6 line wide edges, positioned either below left or below right. Separate
mattes are provided by the generators for edge and fill. Key Edge opacity is
adjustable.
Tally Output
The Tally Relay Module Option provides 64 tally relay closures for on-air source
indicators. This option is a single module which slides into the rear bays.
An Extended Tally Option is also available to allow expanded tally relay outputs.
Three additional Tally Modules provide 64 tally relay outputs per module. The
additional Tally Modules are housed in a separate two rack-unit frame which
connects to the main frame via a standard SMPTE interconnect cable not to exceed
1000 feet (305 meters).
Look-Ahead Preview
The Look-Ahead Preview option provides look-ahead preview processing for both
M/Es, the Program/Preset and the DSK. This option provides a Clean Feed output
in place of the M/E Program Key and allows you to preview the next event on the
preview bus output. Each Look-Ahead Preview Module is a plug-in mezzanine
module that installs below the Primary Wipe Generator Module mezzanine on
each Mix/Wipe Module in the system.
