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.
See www.extron.com for the latest information.
Overview of the VNS 104
The VNS 104 Multi-Stream Decoder Software application allows decoding of up to four simultaneous PURE3 video streams from VN-Matrix 200/225/250 Series and VN-Matrix 300/325 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 does 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.
VNS 104 Multi‑Stream Decoder • Introduction and Installation 1
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 200/225/250 Series and VN-Matrix 300/325 Series encoders, VN-Matrix Enterprise Controller, and VNM Recorders for more detailed information about these devices. This documentation is found at www.extron.com.

Figure 22. Screen Formats as Displayed in the Decoder Window
18VNS 104 Multi‑Stream Decoder • Operation
Decoded Window Splash Screen
Each decoded window can 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 can also be disabled from the Enterprise Controller (see the Enterprise Controller User Guide).
NOTES:
• A custom splash screen may be added and used in place of the supplied design (see Application Configuration on page 13).
• Only one splash screen can be used at a time. The same splash screen is applied to all decoder windows.
Decoded Window Status Messaging
Status text can be overlaid at any of nine 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
Stream assigned and available [encoder name]
Stream assigned but not available No source data stream
No stream assigned (Stream = none) 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 on which it resides.
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 of 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 (see System Requirements on page 3).
20VNS 104 Multi‑Stream Decoder • Performance
Single stream limit
When PC resources are insufficient to support decoding and display of all streams, the connection for a single stream is temporarily suspended giving the resources time to recover. A splash screen is displayed in the window of the affected stream (see figure 23).

Figure 23. Decoder Window, Single Stream Limit
Each decoded window can have its stream suspended independently of the other decoded windows. The administrator is advised to reduce the bit rate of the affected stream or streams.
Quad stream limit
When PC resources are insufficient to support decoding and display of any incoming streams, all existing connections are suspended for 65 seconds allowing the PC to recover. The splash screen is displayed in all decoded windows (see figure 24).
Quad_Split.decoder3Stream suspended... Please wait...
Quad_Split.decoder2Stream suspended... Please wait...

Under these circumstances, the administrator is advised to reduce the bit rate of one or more of the streams.
