AuxKey Configuration with MultiDSK Option Installed
In the above example:
• The first two groups of four are used to provide the optional S4MDX:056
MultiDSK circuitry with video sources for DSK 3 and DSK 4.
• The third group of four is not configured as AuxKeys and is fully configurable.
• The last group of four is configured as a mixer/keyer. Output K13 is the first
AuxKey “program” output, output K14 provides an identical second AuxKey
program output, output K15 is the AuxKey preview output, and output K16 is a
Clean feed output taken after the mix stage but before the keyer.
AuxKeys significantly increase the keying power of the switcher but do so without tying up
an MLE. AuxKeys are configured using the menu system, and controlled via Custom
Control macro buttons, or by temporarily using the buttons of an MLE.
Applications for AuxKeys include:
• Downstream bug insertion. This can ensure that a logo remains inserted
regardless of what is being done in the MLEs. This frees up MLE keyers.
• Multi-language applications. Add CG keys to clean feed outputs. This often frees up
one or more MLEs.
• Multi-client applications. Add keys to MLE outputs that present a variation on
the main program output. This often frees up one or more MLEs.
• Multicasting. Produce programming for two regions simultaneously but brand
them differently without consuming MLE keyers and adding production
complexity. This frees up MLE keyers.
• Stadium concourse and box seat monitors. Add different sponsor branding to
different stadium locations. This frees up MLEs and eliminates the need for costly and
complex external keyers.
• Pre-keying. Add keys to sources before they are brought into the switcher MLEs.
Time the AuxKeys early and the MLEs late and sources can be fed back into the
switcher as inputs. This frees up MLEs or unwieldy external keyers.
• Pre-mixing. Mix between two sources before they are brought into the switcher
MLEs. This makes it possible to dissolve inside any number of DVE boxes while
