Signal Routing
Source definition data is stored as a part of Engineering Setups. Only one
set of source definition data can be active on a Zodiak system at a time.
Note that source definition is separate from source memory, which speci-
fies what processing is to be applied to the source and can dynamically
change during system operation.
Source to Button Mapping
Source to button mapping makes it possible to organize sources on Zodiak
control panels in a preferred order. For example, cameras can be placed on
the left side or the right side of the button row, whichever is preferred.
Source mapping is distinct from source definition, as source mapping only
involves the location of sources on the control panel and does not affect any
capabilities defined for the sources. Note that E-MEM effects store the
source IDs, not the source select buttons, so remapping sources will not
change the appearance of recalled effects.
Source Memory
Keying and other parameters can be saved to a separate source memory for
every Zodiak system source. These parameters can be applied automati-
cally whenever that source is selected. See Source Memory
on page 76 for
specific information.
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 allows 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 10 , source 2 has been selected on the background A
bus. This signal can now be called background video is available for further
processing.
