Signal Routing
Source mapping is distinct from source definition, as source mapping only
involves the location of sources on the control panel and does not affect the
inputs or names defined for the sources.
Note EMEM effects store Source IDs, not the source select buttons, so remapping
sources does not change the appearance of recalled effects.
You can also assign sources to buttons using the Sidepanel program.
Key Memory
Key parameters can be saved to a separate key memory for every Kayak
HD system source. These parameters can be applied automatically when-
ever that source is selected.
Buses and Crosspoints
A
bus
is technically defined as a signal path where one of several available
inputs can be selected to feed a single output. A crosspoint is an electronic
switch that enable a signal to pass when the switch is closed. On video
switchers, a bus can be constructed containing a series of crosspoints,
which permits selecting which one of several incoming signals will be sent
out the bus. In
Figure 1 on page 31 , source 2 has been selected on the back-
ground A bus. This signal can now be called
background
video and is avail-
able for further processing.
Figure 1. Buses with Crosspoints
Buttons on a control panel can be used to control the switching of cross-
points. The buttons are usually arranged horizontally, making it easy to
imagine the available signals coming in from the top, and the single bus
output signal going out the right side. In earlier generation switchers, the
terms
crosspoint button and crosspoint bus have been used in reference to
control panel source selection.
For a Kayak HD system, the terms source button and source bus will be used.
