About this Guide
About this Guide
This guide provides detailed information on how to install and use the VNS 104
Multi-Stream Decoding Software. The terms “decoder software”, “decoder”, and
“VNS 104” refer to the VNS 104 Multi-Stream Decoding Software. The term “encoder”
refers to a VN-Matrix system hardware encoder. “EC”, “controller”, and “system
controller” refer to the VN-Matrix Enterprise Controller.
Overview of the VNS 104
The VNS 104 Multi-Stream Decoder Software application allows decoding up to four
simultaneous PURE3 video streams from VN-Matrix 200/225 Series and VN-Matrix 300
Series encoders and PURE3 recorded streams in active playback on the network.
PURE3 streams contain video information compressed by the PURE3 codec and used
to transport media signals in real time over an Ethernet network. In addition, a PURE3
stream may contain associated audio content.
NOTE: The VNS 104 Multi-Stream Decoding Software will not correctly display
interlaced source images.
The PURE3 codec preserves three performance factors that affect the delivery of video
over a network:
•
•
•
Low latency
Low bandwidth
High image quality
The VNS 104 software is a Microsoft® Windows® -based PC application installed on a
Windows-based PC. Each VNS 104 installation requires a unique device ID and license.
These are supplied with the VNS 104 and entered as part of the installation process.
NOTE: Only one instance of each VNS 104 device ID is allowed on a system.

A system license, stored on the VN-Matrix Enterprise Controller, manages the number
of connections that can be made simultaneously. The VNS 104 decoder is ideal for use
in monitoring, remote presentation viewing, collaboration, or data visualization. It is also
useful as an alternative to hardware-based PURE3 decoding.
The VNS 104 Multi-Stream Software Decoder is controlled by the VN-Matrix Enterprise
Controller. Stream selection, screen layout, scaling, and audio settings are configured
and assigned by the controller.
See the user guides and supporting documentation associated with the
VN-Matrix 200/225 Series and VN-Matrix 300 Series encoders, VN-Matrix Enterprise
Controller, and VNM Recorders for more detailed information about these devices. This

Decoded Window Splash Screen
Each decoded window may display a splash screen generated by the program. The
splash screen is enabled by default and displayed when a source stream is either not
assigned or not available. The splash screen option may be disabled from the Enterprise
Controller.
NOTES:
• A custom splash screen may be added and used in place of the supplied
• Only one splash screen can be used at a time. The same splash screen is
applied to all decode windows.
Decoded Window Status Messaging
Status text may be overlaid at one of 9 positions on each decoded window. The
messaging provides information on the status of the stream connection.
Status text is authored and enabled by the Enterprise Controller. The size and
positioning of the text, and the foreground and background color are configurable from
the Enterprise Controller.
The status messaging appears as follows:
Status
On-screen Message
[encoder name]
Stream assigned and available
Stream assigned but not available
No stream assigned (Stream = none)
No source data stream
No stream selected
VNS 104 Audio
Whether a single stream is displayed in full screen layout, or multiple streams are
displayed, audio from one of the assigned sources is selected by the controller.
Audio controls include signal level and mute, selected by the Enterprise Controller.
VNS 104 Device Name
The VNS 104 Decoder can be given a user-defined name to help identification in a large
system. The device name is visible in the device list of the Enterprise Controller and is
displayed as part of the status overlay text when it is enabled.
The default name is the same as the device ID entered during the installation of the
VNS 104 software. This value can be changed from the Enterprise Controller.
Multiple Controller Domains
The VNS 104 is able to decode streams that originate from different VNM Enterprise
Controller domains.

VNS 104
Performance
The performance of the VNS 104 depends on the bit rate of the PURE3 streams and the
capability of the PC hardware it resides on.
If hardware limitations are encountered, the image may update more slowly. The
VNS 104 monitors its performance and makes adjustments in real time to ensure the
highest quality video. Decoding a source stream can be suspended when resource limits
mean decoding is no longer possible.
Image Quality and Motion
When the hardware hosting the VNS 104 is unable to sustain performance at the bit rate
of the connected stream, image quality is maintained at the expense of motion. Where a
tradeoff must occur, the application throttles back to support a maximum 30 Hz refresh
rate, independent of the encoded stream.
Host PC Resource Monitoring
The VNS 104 monitors the host PC resources at all times. It can suspend decoding
of a single stream or all streams when resource limits in the host PC prevent normal
decoding.
The application monitors resources and protects against problems that may cause the
VNS 104 application or the operating system to fail.
NOTE: Resource limitations can occur if the bit rate of the streams is such that the
packet density causes UDP frames to be dropped in the network (switch) or in the
PC network card. Resource problems can also occur on a PC platform that does
not meet the minimum requirements.
