VNM 250 System Controller
All matrix systems require one device that acts as the system controller. For small systems
(ten devices or fewer), this can be either a VNE 250 or VND 250. For larger systems, a
VN-Matrix Enterprise Controller must be used.
Systems Controlled by
VNM Enterprise Controller
Systems Controlled by
VNM 250 Device
The VNM Enterprise Controller is able to
control all VN-Matrix systems (large and small)
but is required for large systems (more than
10 devices).
A VNM 250 device can control small systems
(10 devices or fewer). It is less effective as the
system size increases.
The system is controlled through a powerful
web-based user interface served from the
Enterprise Controller. An HLI interface is also
provided for control via an external control
system.
The system is controlled through a more
limited web-based user interface served from
the VNM 250 controller device.
Supports all VN-Matrix devices, including
recorders.
Supports VNM 250 encoders and decoders
and PCs running the VNS 104 software
decoder. Does not support recorders.
NOTES:
•
A small system that includes a VNM 250 device must be controlled by either a
VNM Enterprise Controller or a VNM 250 device.
•
If an incompatible VN-Matrix device is added to a small system controlled by a
VNM 250 device, the controller is unable to detect or control that device.
Transport Protocols Used for Streaming
The source data from a VN-Matrix encoder can be distributed to multiple displays/decoders
(one-to-many) or to a single display/decoder (point-to-point). A previously recorded stream
can be distributed in the same way and can be thought of as an encoder in this context.
A stream can be transported from the source (encoder, recorded stream) to the display
(decoder) using one of three methods:
•
Multicast Real-time Transport Protocol (RTP)
on page 4.
•
Unicast Real-time Transport Protocol (RTP)
•
Transmission Control Protocol (TCP)
on page 5.
