User Manual
Router Destination (Feeding AUX)
This is a setting that identifies the NV9000 router destination that feeds an auxiliary device such
as a waveform monitor. The setting represents a physical connection between the router and
the auxiliary device.
As a panel operator selects a video source on the aux bus, the Imagestore 750 issues commands
to the NV9000 system controller to perform appropriate auxiliary source switches. In that way,
the panel operator controlling an Imagestore 750 has an “extra” set of controls (i.e., the aux
buttons) with which to view sources on a monitor, or to route sources to some other device for
another purpose. All source switches are tallied back to all iMC control panels that own the
channel.
Router Sources (Fed by PGM, PST, CLN, and MON Outputs)
 Note: See the definitions of router sources and definitions under Router Destinations
(Feeding Program and Preset Inputs) above.
These settings identify the NV9000 router sources that are fed by the Imagestore 750’s program,
preview, clean-feed, and monitor outputs. Connections to these sources allow the NV9000
system to route the Imagestore 750’s outputs to a local monitor wall.
These settings represent physical connections between the Imagestore 750 and router. Conse-
quently unique sets of sources must be defined for every Imagestore 750 within the Master
Control system.
Router Source (Fed by BLACK/SILENCE)
This setting identifies the NV9000 router source that corresponds to black/silence in a video
standard that is appropriate for this channel processor. The source allows the NV9000 system to
route black/silence to the local monitor wall when gaps appear within the current source group.
Router Source (Fed by USER 1-20)
These 20 settings identify the NV9000 router sources corresponding to custom-defined sources
for this Imagestore 750. Such sources can be used to route outputs from a backup channel
processor to the local monitor wall, or to view “mirrored” HD/SD channel processors in parallel.
Graphics Co-Processor Feeding Fill and Key
The Intuition XG co-processor (also known as the “slave” device) provides advanced graphics to
the Imagestore 750 using one of the 3 available external fill and key inputs. The graphics are
then keyed onto the video background signal using any of the 4 available keyers (DSKs). The fill
provides the graphics signal, and the key provides the transparency.
You can use the Imagestore 750 configurator to identify which external fill and key inputs
receive signals from the Intuition XG. The configuration also specifies to which DSK layer
external graphics are assigned and specifies the automatic keying behavior of the assigned DSK
as Intuition XG layers cut up and down.
You should also configure the system to allow slave layer states and other system information to
be communicated between the Imagestore 750 and the Intuition XG. This can be done over an
RS-232 serial connection or over Ethernet.
