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.  
See www.extron.com for the latest information.  
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.  
VNS 104 Multi‑Stream Decoder • Introduction and Installation

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  
documentation is found at www.extron.com.

Configuration  
This section outlines the steps required to configure the VNS 104 software and connect  
to the VN-Matrix Enterprise Controller. Topics that are covered include:  
VN-Matrix Enterprise Controller Licensing  
The VN-Matrix Enterprise Controller must be licensed to allow the VNS 104 to connect.  
Ensure the controller has the appropriate license checksum and structure present. The  
license sets the maximum number of simultaneous software decoders that may run on a  
VN-Matrix system. The system controller limits the number of software decoders to the  
maximum set by the license.  
See the VN‑Matrix Enterprise Controller User Guide, at www.extron.com for information  
about adding and managing the controller license.

VNS 104 Operation  
This section describes the process for decoding content using the VNS 104  
Multi-Stream Decoder. Topics that are covered include:  
VNS 104 Multi-Stream Software Decoder  
The VNS 104 Software Decoder provides viewing of up to four live PURE3 streams from  
VN-Matrix Series encoders that are on the same network. You can also view up to four  
PURE3 recorded streams that are in active playback on the same network. Before you  
can view content from the encoders, you need to configure the software and connect to  
the VN-Matrix Enterprise Controller that is controlling the other devices on the network  
If the VNS 104 is correctly configured during installation, it automatically connects to the  
Enterprise controller. The Enterprise controller configures the VNS 104 software to run in  
the same mode as it was in when last used.  
Figure 15. VNS 104 Connected to Enterprise Controller (Splash Screens Only)  
VNS 104 Multi‑Stream Decoder • Operation 13  
 
 
If the VNS 104 was not configured during installation, or changes to the controller,  
the PC, or the network have occured and the VNS 104 is unable to contact the  
controller, the controller is not properly licensed, or the VNS 104 shares the same ID or  
checksum with an existing VNS 104, then the application displays “Unable to contact  
controller” on the splash screen (see figure 16, below).  
Check the Enterprise controller IP address and port number settings in the network  
If the values are correct, ensure that the controller is powered and connected to the  
same network as the VNS 104.  
Connecting to a VN-Matrix Enterprise Controller  
NOTE: Ensure that the computer using the application, the controller, and all  
VN-Matrix sources are connected to the same network.  
To connect to a controller and access the content of the available sources, open the  
VNS 104 application. Either:  
EXTRON  
Double-click the icon on your desktop.

To switch from the reduced screen to full screen, select Fullscreenfrom the toolbar or  
double-click anywhere on the screen.  
To return to the reduced screen size, press <Esc> on the keyboard or double-click  
anywhere on the screen.  
When the VNS 104 is in reduced screen mode, the toolbar and window borders are  
visible. In full screen mode, only the decoded streams are displayed.  
For both reduced screen mode and full screen mode, the size of the available viewing  
area determines the scaling of the decoded stream.  
VNS 104 Display Format and Scaling Modes  
The VNS 104 has no capability to modify or change the streams, stream format, screen  
layout, stream content, or window selection. All stream formatting and window layout  
selection is done from the VN-Matrix Enterprise Controller. Individual stream selection  
and configuration is also set by the controller. The VNS 104 can be configured by the  
controller to run in either quad (4) or single (1) stream display layout.  
When a stream is assigned by the Enterprise Controller, the decoded image is displayed  
in the decoder window in the format assigned by the controller. When a stream is  
assigned but not available, a black screen is displayed. If a splash screen is enabled, it is  
displayed instead.

is displayed in the available screen or window size.  
Fill: The entire source image is scaled to fit the available window or display size.  
Aspect ratio is not maintained.  
Unity: The source will be displayed at its native resolution, positioned at the center  
of the decoded window as follows:  
Display viewing area resolution is less than the source resolution:  
A reduced size view of the image is displayed, anchored at the center of the  
image. No scroll bars are shown at the edges and panning of the image is not  
possible.  
Display viewing area resolution is equal to the source resolution: The  
entire image is displayed at its native resolution.  
Display viewing area resolution is greater than the source resolution:

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.  
VNS 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 21).
