C. Misc. Information
Appli cation Notes
The master control operator chooses which router source to map to an MCPM main source. Control
panel buttons will display the source mnemonics used in the NV9000 system.
Such source mapping is an intrinsic feature of the master control system.
You can also apply source mapping to keyers, squeeze backgrounds, and audio over sources,
although this kind of source mapping is not automatic. A master control operator can execute router
salvos at the control panel that switch keyer sources, background sources, audio over sources, and
in fact, any sources.
The master control operator can also use any NV9000 control panel to perform router operations.
Using External Router Sources
External router sources (ERS) are a topic for MCPM configurers and system designers. The master
control panel operator need not and probably will not know which sources are
external (from rout-
ers) and which sources are local (connected at the frame’s backplane), although the operator might
have to load and control media in local devices.
Much of ERS is customer-dependent. At best, this document can present some general guidelines.
An NV5100MC or NV5128-MC frame has 128 potential input ports in 8 input card slots. ERS can
consume up to 30 ports — video or audio. The master control system must balance cabling between
local sources and external sources.

If all audio is embedded, the cabling job is easier.
ERS configurations apply to MCPMs. Two MCPM configurations that use completely different
ERS inputs could consume 60 inputs. It is to your advantage to configure ERS inputs for all
MCPMs in one frame in exactly the same way. (Doing so makes the NV9000 configuration simpler
too.)
You must have a number of video input cards and audio input cards that support your application.
Inputs come in multiples of 16. (An audio input is stereo pair, but it can be split.)
MCPMs occupy 1, 2, 3, or 4 output slots. MCEs occupy from 1 to 3 slots. You could conceivably
have 8 MCPM-MK-SDs in one frame. MCPM backplane modules occupy 1, 2, or 3 backplane
slots. MCPMs (including MCEs) can coexist in a frame if you have the slots for them.
Note that MCPM-MK-HDs have 16 inputs on their own (2-slot) backplanes and those inputs are
not shared. All main, squeeze, and key sources, external and local, must come through the those 16
inputs, and not from the motherboard.
An MFR (multi-format router) can coexist in the frame with the MC system. The combination can
offer great benefits

but imposes constraints on the MC system (i.e., fewer slots for MCPMs, dedi-
cated slot assignments for the MFR with port cards and time-code cards, HD output cards in
MCPM wings, etc.) The MFR can manipulate/manage some of the signals of the MC system.
Configuring ERS
ERS configuration is performed entirely in MasterConfig. Any MCPM, including MCEs, can per-
form external router source selection. ERS must be enabled in MasterConfig’s general settings.
