Multiple Suite Resource Sharing
The Resource Sharing feature permits the allocation of GV K-Frame XP system resources
between suites. This allows independent system operation from multiple locations without
conflict.
Logical resource assignments allow the reuse of E-MEM effects in any suite regardless of
which specific hardware resources were allocated.
Each suite can be run with its own Suite Prefs settings, and two different Panel Prefs
preference settings can operate simultaneously in each suite. These preferences can be
saved and loaded, permitting reliable system changes to meet varying requirements.
The system retains the current suite/resource relationships. If the system powers down or is
reset, resource allocations for each suite are restored when the system returns to operation.
Collaborative Resource Sharing
Collaborative resource sharing permits a group of operators to have simultaneous access to
a resource. For example, a video operator may want access to an M/E so he can set up a
chroma key, but the operator also wants control of that M/E so that he can put the chroma
key on air. This type of sharing is available simply by installing additional Control Panels.
Corroborative system operation has inherent limitations. Since one operator can change
the settings used by another operator, it is assumed the operators are in close
communication with each other so they can avoid system control conflicts.
If two conflicting corroborative commands are sent, the switcher system ends in the state
of the last command processed. For example, one operator could select a source on a bus of
an M/E at nearly the same time another operator selects a different source on that same
bus. The output of that M/E will momentarily display the first source and then switch to the
last source selected, possibly causing an apparent flash on that output.
The Resource Sharing feature allows collaborative sharing of system components with
different User Prefs. For example, when a smaller 25 source panel is used in a corroborative
environment with a larger 35 source panel, the button mapping for the two panels must be
different because of the different number of source buttons available.
Independent Resource Sharing
Independent resource sharing isolates an operator or group of operators from other
operators, by defining separate suites. When one suite has acquired a resource, only the
operator or group of operators in that suite will be able to control it. An example of
independent sharing is splitting a 4-M/E switcher system into two independent 2-M/E
switchers.
When a suite acquires a physical resource (like an M/E) it uses that resource logically. For
example, the M/E B physical resource can be used as a logical PGM PST bank. Each of the
two switchers created can therefore have their own PGM PST bank, and this allows effects
built in one suite to operate correctly when recalled in another suite. Effects will also run
correctly in the same suite when run at a later time even if different physical resources have
been acquired. Resources can be released by a suite. Once released, these resources can be
acquired by another suite. This permits dynamic reconfiguration of the system resources to
meet varying operational requirements.
