VN-MATRIX User Guide Section 1: Introduction SECTION 1: Introduction I458GB issue 6 Page 9
Section 1: Introduction VN-MATRIX User Guide What is VN-MATRIX? VN-MATRIX is used to distribute RGB video/graphics from a source computer (or similar graphical device) across an IP network to one or more viewing stations. An RGB signal is captured/acquired by a VN-MATRIX unit and encoded in to a TCP or RTP data stream for transport across a local area or wide area network.
VN-MATRIX User Guide Section 1: Introduction Functional Overview The VN-MATRIX can be configured to operate in one of two modes: As an encoder to encode a source and stream it across a network, As a decoder to decode a VN-MATRIX data stream from a network. Therefore, any VN-MATRIX system will comprise at least two devices, one configured as an encoder and the other as a decoder. However, multiple encoders and decoders can co-exist on the same network.
Section 1: Introduction VN-MATRIX User Guide Control Capability Source Control Loop-through connections are provided on the VN-MATRIX for the source computer keyboard and mouse. Local keyboard and mouse control of the source computer is fully maintained while connected to the VN-MATRIX. In addition, keyboard and mouse functions can be remotely controlled from the viewing station.
VN-MATRIX User Guide Section 1: Introduction Network Requirements VN-MATRIX uses highly efficient compression algorithms to minimize the amount of data needed to be transported across the network. It is, however, crucial to the effective operation of VN-MATRIX that sufficient data throughput can be achieved, especially where multiple sources are being encoded. The efficiency of a network will be directly affected by the speed and configuration of each element within its infrastructure, e.g.
Section 1: Introduction VN-MATRIX User Guide Example System Application The diagram below shows an example system application utilizing eight VN-MATRIX units. Four are configured as encoders (sources) and four as decoders (displays). Each device is connected to a network. Configuration of each device, including which source is displayed on which display, can be achieved by any PC/laptop on the same network, using the VN-MATRIX Integrated Web Management System.
VN-MATRIX User Guide Section 1: Introduction Data Transport Methods Source data from a VN-MATRIX Encoder can be distributed to multiple displays/encoders (one-tomany) or to a single display/decoder (point-to-point). Video data is transported from the source (encoder) to the display (decoder) using one of three methods: Multicast RTP Unicast RTP Unicast TCP A description of each method, together with its advantages and disadvantages, can be found on the next few pages.
Section 1: Introduction VN-MATRIX User Guide Multicast RTP This method uses a real-time variation of UDP (User Datagram Protocol), called RTP (Real Time Protocol). Multicast RTP allows a source to be displayed on any number of displays. . The source encoder uses RTP to send data to a multicast group. The source does not need to know the IP address of any decoders that use that source. RTP provides very low latency which is important for video transport.
VN-MATRIX User Guide Section 1: Introduction Unicast RTP Like Multicast RTP this method uses a real-time variation of UDP protocol, called RTP. This method can be used where the network infrastructure does not support multicast traffic. Typically this should be used as a point-to-point configuration (i.e. single source to single display) but can be used for up to four displays.
Section 1: Introduction VN-MATRIX User Guide Unicast TCP This method transports data using standard TCP (Transport Control Protocol) and should only ever be used for single point-to-point transfer of data. TCP is a connection-based protocol and, therefore, data is guaranteed to be delivered. However, in the event of excessive network traffic, delivery may be delayed which will impact on real-time performance. The decoder defines which source to ‘connect to’.

Section 4: Advanced Setup Procedures VN-MATRIX User Guide Encoder Set Up This section provides details for advanced set up options for a VN-MATRIX encoder.
VN-MATRIX User Guide Section 4: Advanced Setup Procedures Advanced Source Setup For most applications it is recommended that the source input of VN-MATRIX is set to auto mode. This enables the device to detect the electrical/timing characteristics of the input signal and determine the exact source type. It will then invoke the appropriate input parameters for optimum processing of that source. This also has the advantage that if the input source changes to another source type (e.g.
Section 4: Advanced Setup Procedures VN-MATRIX User Guide Video Setup Page All advanced source setup is achieved via the Video Setup page. This is accessed by clicking the Video Setup tab on the Configure (videoPort) page for the relevant VN-MATRIX encoder: For most source types it is recommended that you select the auto input mode, allowing full auto-detection of the source. To apply a fixed input mode, select the required mode from the drop down list and click Update or Save.
VN-MATRIX User Guide Section 4: Advanced Setup Procedures Fine-Tuning a Source (manual overrides) The following adjustments are classed as manual overrides. The chosen settings are not saved as part of the current source mode and, once applied, will remain in force until they are changed. Phase (Pixel Clock) Macrovision Defeat When an analog graphics signal is being digitized it is essential that each pixel is sampled as close as possible to its center in order to obtain a stable value.
Section 4: Advanced Setup Procedures VN-MATRIX User Guide Creating a Custom Input Mode A custom input mode allows you to specify your own values for the various input parameters, e.g. number of lines/pixels of active video, the start line/pixel of active video, etc. When VN-MATRIX performs an auto-detect on a non-standard source, it will usually be able to choose an existing mode that ‘best matches’ the source.

VN-MATRIX User Guide Section 4: Advanced Setup Procedures Managing Compression & Bandwidth Settings VN-MATRIX can apply various types of compression to an input source in order to reduce the volume of source data being streamed across the network. In addition, various parameters are provided to manage and, if necessary, limit the amount of data flow to ensure that the available network bandwidth is not exceeded.
Section 4: Advanced Setup Procedures VN-MATRIX User Guide Bandwidth (source) Page All advanced source setup is achieved via the Bandwidth (source) page.
VN-MATRIX User Guide Section 4: Advanced Setup Procedures Compression Settings The Luminance and Chrominance settings can be individually modified (Lock unchecked) or they can be locked together (Lock checked). When locked together the Chrominance tracks the Luminance setting plus 2 stops. The Luminance compression can be modified between 0 and 10, where 0 is no compression and 10 is maximum compression. The picture may look noticeably ‘blocky’ at higher compression values.
Section 4: Advanced Setup Procedures VN-MATRIX User Guide Bandwidth Management Settings VN-MATRIX can apply various bandwidth management policies and these can be selected using the Mode parameter: None – no bandwidth management policy will be followed apart from the underlying compression settings. Manual Frame Drop – allows the user to specify the precise fraction of frames to drop.
VN-MATRIX User Guide Section 4: Advanced Setup Procedures Audio Compression The S/PDIF digital data bus can carry two types of data: 2 channel (stereo) uncompressed audio, or encoded digital data, typically AC-3 (Dolby Digital) format. VN-MATRIX supports limited compression of S/PDIF audio sources. This is controlled by the Compression setting on the Configure (audioPort) page.
Section 4: Advanced Setup Procedures VN-MATRIX User Guide Decoder Set Up This section provides details for advanced set up options for a VN-MATRIX decoder.
VN-MATRIX User Guide Section 4: Advanced Setup Procedures Setting Optimum Playback Delay During playback of a source stream, data is transported from a VN-MATRIX encoder across the network and into a buffer on the VN-MATRIX decoder. Data is then read from the buffer and output to the display. Because of the inherent time delay (latency) for data to be transported across the network, it is clearly not possible for the decoder to display the source at exactly the same instant as it is being encoded.
Section 4: Advanced Setup Procedures VN-MATRIX User Guide Bandwidth Monitoring Page Playback Delay is adjusted via the Bandwidth page for the VN-MATRIX decoder.
VN-MATRIX User Guide Section 4: Advanced Setup Procedures Adjusting the Playback Delay n Open the Bandwidth page for the video object. o Enter a value into the Playback Delay field and click the update button. p Check the Pipeline Status indicator to ensure that the Playback Delay is at a valid level: Setting is valid and should give a stable image.

Section 5: Serial Transport & Control Methods VN-MATRIX User Guide SECTION 5: Serial Transport & Control Methods Page 86 I458GB issue 6
VN-MATRIX User Guide Section 5: Serial Transport & Control Methods Overview Routing of external serial (RS-232) communications can be achieved between any VN-MATRIX units on the same network. Serial traffic can be unidirectional as part of a source stream (encoder to decoder) – Data Stream Mode - or bi-directional and independent of any source stream – Passthrough Mode.
Section 5: Serial Transport & Control Methods VN-MATRIX User Guide Passthrough Mode In this mode, data received by a device ‘input’ is transmitted using TCP/IP over the network and then converted back to serial data by a device ‘output’. Data flow is fully bi-directional and totally independent of whether a VN-MATRIX is configured as an encoder or decoder. One device within a passthrough group is designated as a server.
VN-MATRIX User Guide Section 5: Serial Transport & Control Methods Remote Control Mode In addition to ‘passthrough’ operation outlined above, a VN-MATRIX serial input can be configured to communicate directly with the VN-MATRIX controller. This provides basic serial ‘remote control’ functionality of a VN-MATRIX system, such as display source switching. A full list of serial commands can be found on page 93. One or more devices are designated as clients (in remote control mode).
Section 5: Serial Transport & Control Methods VN-MATRIX User Guide Setting-up a Serial Data Stream Login to the Web Interface (see page 41). From the Device List page click on the required encoder device. From the Device page click the Serial tab to display the following: Using the mode listbox select the server option.

Appendix A: Guide to IP Addressing VN-MATRIX User Guide APPENDIX A: Guide to IP Addressing Page 124 I458GB issue 6
VN-MATRIX User Guide Appendix A: Guide to IP Addressing What is an IP Address? A full explanation of IP addressing is beyond the scope of this user guide. However the following details will provide you with enough information to get started. An IP Address is a 32-bit binary number that is used to identify each device on an Ethernet network. This number is usually represented by four decimal numbers (each in the range 0 to 255) separated by dots, e.g. 198.123.34.240.
Appendix A: Guide to IP Addressing VN-MATRIX User Guide Choosing IP Addresses If your VN-MATRIX units are connected via their own independent network, then follow the guidelines below for choosing your IP Addresses. However, if you intend connecting your VN-MATRIX units to an existing network, you will need to advise the network administrator and ask them to allocate suitable addresses to you. On an independent network you can (in theory) use just about any addresses you wish.
VN-MATRIX User Guide Appendix A: Guide to IP Addressing Using the ‘Ping’ Utility to Test Communications You can test for communications between a Windows computer and another device on the same network by using the Windows Ping utility. From the Windows Desktop of the computer, click on the Start button, and select Run from the pop-up menu. The Run dialog box will appear. In the Open box, type in the following command: ping xxx.xxx.xxx.xxx –t where xxx.xxx.xxx.xxx is the IP Address of the device (e.g.
VN-MATRIX User Guide Appendix C: Browser Configuration APPENDIX B: Understanding Network Performance Page 128 I458GB issue 6
Appendix B: Understanding Network Performance VN-MATRIX User Guide Network Characteristics There are a number of characteristics of networks that have to be taken into account when transmitting image data. When a conventional analog or digital video signal is sent from a source to a display, the image is transmitted in real time with negligible delay (or “latency”). The signal itself is continuous with (even in the case of a digital signal) very little redundancy in the signal (i.e.
VN-MATRIX User Guide Appendix C: Browser Configuration Nodes, Switchers & Routers An Ethernet Local Area Network (LAN) will have a number of nodes, and in principle all nodes can communicate with each other. The principle used is “Carrier Sense, Multiple Access/Collision Detection” or CSMA/CD. This means that when not transmitting, all nodes are listening. When a node transmits no other node attempts transmission. However, signal speed limits mean that a “collision” is possible.
Appendix B: Understanding Network Performance VN-MATRIX User Guide Protocols For communication to work over networks there must be some formality about how communication is done in order to ensure inter-operability between different systems. The ISO proposed a model for this in its Open Systems Interconnection (OSI) model.
VN-MATRIX User Guide Appendix C: Browser Configuration Comparison between UDP and TCP The two different transport layer protocols are compared in the following table: UDP Connectionless Datagrams must be formatted in application Multiple applications using ports Unreliable (best effort) communication No flow control (must be in application if required) No error recovery Multicast possible (one to many) Minimum latency TCP Connection oriented Automatically generates datagrams from bitstream Multiple appli
