Product Overview
Router Controller Configuration
A MV-831 Multiviewer module fits into a
pair
of adjacent Sirius 830 input/output module slots
(both front and rear). More than one MV-831 may be fitted into a Sirius 830 router.

, on page 40, for router front and rear
module slot details.)
Router Controller Configuration
From a router controller perspective, the MV-831 module’s input/output functionality appears
to a host Sirius 830 router like a standard video input module and a standard video output
module. And this input/output functionality is under the control of the host router and is
unchanged from normal input/output router modules. The MV-831 module’s multiviewer
functionality, however, is essentially a separate sub-system.
The MV-831 has access to its own router inputs and router destinations. In particular, each
destination may be configured to either a) have routing redundancy, or b) provide up to 24-off
extra destinations to each MV-831 module. It is configured in the host router’s router controller
configuration. This determines the mixture of router sources, destination outputs and MV-831
module inputs monitored by the MV-831’s multiviewer.
From a router controller configuration point of view, an MV-831:
• has a specific input/output port type;
• has specific module types;
• has access to internal Sirius 830 video crosspoint destinations in the second (redundant)
crosspoint (i.e. destination numbers above 288); and
• can use the internal LTC signal.
Router Controller Configuration Items
The host router’s controller configuration needs to be modified to accommodate all the fitted
MV-831 Multiviewers and any extra external crosspoint control required.
Router controller configurations differ. The controller configuration of any host router is
tailored to the system it is part of and to that particular router’s application. Router controller
configurations are created, edited and managed with the Grass Valley WorkBench software
tool.

Note:
Second (redundant) video crosspoint module - Exposing crosspoints to external
control:
Strictly speaking, not all of a host router’s redundant crosspoint destinations need to be
exposed for external control; only those used directly by MV-831(s) need to be given a
control interface (or added to an existing control interface).
However, all redundant crosspoints may be exposed for external control because any
crosspoints of the second crosspoint module that are used for redundancy are
systematically unaffected by external control.
Setting up all of the crosspoints of the second (redundant) crosspoint module for external
control simplifies host router controller configuration when adding various MV-831s.
