About Source Patching
44
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 other recorded 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 engineering sources.
The Source Patch menu 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 to two Logical IDs, and one of these Logical sources can
be given a Source Rule that can be cut on Key 5, and the other be given a Source Rule that
cuts on Key 6. Selecting these different versions of that same source would automatically
apply or clear the keys, as needed.
