Signal Routing
Re-Entry
Switchers with multiple MEs generally have re-entry capabilities. Re-entry
permits the switcher to select the output of one ME for use as an input
source to another ME. The signals are routed internally.
The Kayenne system supports ME re-entry in any order. For example, an
output of ME 2 can be sent to ME 1, and an output of ME 1 can be sent to
ME 3. Infinite looping re-entry (for example, ME 1 sent to ME 2 and ME 2
sent back to ME 1) is allowed but should be done with great caution.
Utility Buses
Besides the standard A and B background buses, each Kayenne ME also
accepts Utility 1 and Utility 2 inputs. Kayenne Utility buses can be used to
select signals for special purposes, and have no relation to the background
buses. For example, a video signal selected on a Utility bus can be used to
fill a keyed Borderline border, to feed a custom pattern into a wipe gener-
ator, or create a custom border wash pattern. When the ME is in Double-
Take, Split ME mode, the Utility Buses contribute to the secondary mixer of
that ME allowing for independent ME transitions
Outputs
Video production switchers generate several different video outputs (Pro-
gram, Preview, etc.). A final program output from PGM PST is typically
sent to the Master Control/Transmission for broadcast and/or to servers or
VTRs for recording. Individual ME program and preview outputs and an
additional switched preview output are sent to monitors in the control
room. These outputs may also be routed elsewhere in the facility. Aux Bus
outputs may also be used for studio display systems, ISO feeds, and
complex clean feeds.
Output Mapping
Unlike earlier generation switchers, all the Kayenne system outputs are
configurable. There are no dedicated output connectors. Any signal can be
assigned to any output connector, which provides flexibility and control of
the number of fixed and up to 46 Aux bus outputs the system will have. A
fixed output is always the same, while an Aux bus’s output can change
depending on what source has been selected on that bus. Once the fixed
system outputs have been assigned, all the remaining outputs can be
assigned for use with Aux Buses. When the system is configured, the out-
going signals are assigned to connectors on output modules located at the
back of the Kayenne Video Processor.
