Section 2 — Concepts
The most important difference between a fixed output and aux bus is that
an operator has control over an aux bus but a fixed output always provides
the same signal. Aux bus outputs also support YUV color correction and
optionally RGB color correction with E-MEM and macro control. If an
output is assigned to a fixed output, any color correction settings are
bypassed and the output is set back to unity default.
Aux Buses
Video production switcher Aux Buses can be used to select and route
sources to specific destinations. For example, a source selected on an Aux
Bus can be sent to an ISO recorder for instant replay. This can be done
directly by the Technical Director while he switches the program. Remote
Aux Panels can be used to give different operators control over one or more
Aux Buses.
On the Kayenne system, each Remote Aux Bus panel can have its own
source to button mapping. Source name displays on the 2 RU Local Aux
Module show what source is currently available for each button. Aux Buses
can also be configured in pairs, to send matching key cut and key fill signals
to external devices, Remote Aux Panel IP Address, Logical Aux settings,
and Button Mapping are exclusively saved with the Eng Setup file.
Point Of Use
The Kayenne system can share some resources for use at different locations.
The location where a resource is being used is called a point of use. Different
types of resources are shared differently.
Floating resources (like Transform Engines) move between points of use,
and the parameters controlling these resources are considered part of the
point of use. These resources are used at only one point of use at a time.
When the resource floats to the new location, its behavior changes. For
example, a Transform Engine can be set for 0.25 Z rotation (parameter) on
ME 1 Key 2 (point of use). That same Transform Engine can then be
assigned to ME 2 Key 3 and set to a Z rotation of 0.0. When the Transform
Engine is reassigned back to ME 1 Key 2, the 0.25 Z rotation parameter will
be restored.
Other Kayenne system resources behave differently. For example, wipe
pattern generator resources can be used for an ME wipe transition, as a
preset pattern, as a mask, or at other points of use. It is also possible to
assign the output of the same wipe pattern generator to different points of
use at the same time. For efficient operation, the Kayenne system has
divided the parameters controlling wipe pattern generators and related
utility bus functions into two categories; shared generator parameters and
point of use parameters. The set of parameters for the shared generator are
used by all points of use, so changing one of these parameters will affect all
