About Source Patching
Facility engineers need to know the exact routing of all the video signals
connecting all the devices they are responsible for. These engineers need to
be able to identify video signals in a way that will help them connect
devices properly. Production personnel, on the other hand, are interested in
the content they work with for their shows, and are generally not con-
cerned about which individual device or routing path is used to make those
signals available. They just need a way to identify the content and access it
when they need it. To support these differing needs, two source naming
mechanisms are available on GV Switcher systems; Engineering Source ID
and Logical ID.
By default engineering source IDs are mapped one-to-one with logical IDs
but Source Patching can be used to quickly set up production elements for
use in a different facility. For example, a show’s effects, DDR clips, and
taped material may have been built in one production truck with one set of
devices, but the next show is scheduled for a different truck. Previously, to
use effects in the other truck the Technical Director (TD) would need to edit
the engineering source definitions in the new truck so they exactly matched
the old truck. By remapping the engineering sources of the devices in the
new truck to the logical sources used to build the effects, all the effects can
be used without having to edit them. Source Patching can also be used to
quickly swap out a defective device during a show without having to
reconfigure the engineering sources. In this case logical names seen by the
production personnel would be identical for that content, even though the
actual device playing the material changed.
Note Source Patching is the bridge between engineering sources and logical
sources. Both TD and EIC should make reference to the Source Patch menu
when resolving source issues. The mechanism is similar in concept to a
physical patch panel. Effects and all source selections are based on logical
sources. Tally and associations with external devices are based on engi-
neering sources.
The Source Patch menu ( Figure 18 ) scrolling list has more Logical IDs than
physical inputs. These can be used to permit alternative processing of the
same incoming signal. For example, the same camera input can be assigned
