system is configured, the outgoing signals are assigned to connectors on
output modules located at the back of the Kalypso Video Processor.
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 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. It is also possible to assign control of an Aux Bus to an external
device, like a DPM, and allow that device to directly switch sources as
required.
On the Kalypso system, each Remote Aux Bus panel can have its own
source to button mapping. Source name displays on the Local Aux panel
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.
Point Of Use
The Kalypso 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
M/E 1 Key 2 (point of use). That same Transform Engine can then be
assigned to M/E 2 Key 3 and set to a Z rotation of 0.0. When the Transform
Engine is reassigned back to M/E 1 Key 2, the 0.25 Z rotation parameter
will be restored.
Other Kalypso system resources behave differently. For example, wipe
pattern generator resources can be used for an M/E 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 Kalypso 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
