Resource Sharing and Point Of Use
The KayakDD system has 1 dedicated BNC output connector per aux bus.
Resource Sharing and Point Of Use
The Kayak system can share some resources for use at different locations.
The location where a resource is being used is called a point of use.
The wipe pattern generator resources can be used for an M/E wipe transi-
tion, as a preset pattern, as a mask, or at other points of use. It is also pos-
sible to assign the output of the same wipe pattern generator to different
points of use at the same time.
For efficient operation, the Kayak system has divided the parameters con-
trolling 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 locations where that
wipe pattern generator is being used at that time. Separate sets of point of
use parameters, however, are maintained for each Kayak system point of
use.
These settings are used only by each individual points of use, so changing
them will not affect any other point of use.
For example, a wipe shape (box, circle, etc.) is a generator parameter, but
the softness of the shape’s edges is a point of use parameter. If the same
wipe generator is used by both an M/E wipe transition and a preset pat-
tern, adjusting softness at one point of use will not affect the other’s soft-
ness settings. However, changing the pattern shape affects both locations.
Transition
A transition is a change from one image to another. The Kayak system sup-
ports three basic types of transitions:
• Cut
• Mix
• Wipe
• DPM (optional)
A transition can be applied to the entire picture, or to only the background
or keyed elements of the picture, and can include multiple elements.
