3 1 IMPLEMENTATION SVSi's Networked AV products offer large seamless matrix switching and video-over-ip content distribution for professional A/V dealers. Our Networked AV solutions provide unsurpassed video and audio quality at bandwidths appropriate to any network segment or link. Matrix switches as large as 650x450 have been constructed on a house network using SVSi's Networked AV products. Alternatively, many customers choose to deploy on physically separate networks in order to use low-cost network appliances but keep video traffic separate from data or voice. In this latter case, control is through a house network connected through a blocked port to the video network. Items can be purchased through our network of domestic and international authorized partners and are backwardly compatible with SVSi's legacy Networked AV products.

4 SVSi provides Crestron and AMX modules to our authorized partners that allow either direct control of each decoder, networked video recorder or windowing processor or relayed commands through an N8000 controller. Please contact SVSi for third-party control modules. Implementation Considerations SVSi's Networked AV solutions are based on gigabit Ethernet protocol. Networked AV devices can be installed on a physically separate network or converged onto an existing gigabit Ethernet network. Network devices must have unique IP addresses. Any control software or device must have an IP address in the same subnet as all Networked AV devices. Any layer-3 switch with IGMP-query capability or layer-2 switch with VLAN capability can be used for routing Networked AV video streams. A video network can incorporate 10/100-baseT devices such as third-party controllers or point-of-sale devices. However, video traffic must be blocked from going into the network port to which the device is connected. This can be done through an extra switch port on an SVSi device or through a port on a switch with IGMP-query enabled. N3000 (and N2000 in some cases) video streams can be routed through 100-baseT network appliances. However, if data or voice are converged on the network, careful consideration must be given to bandwidth management or video frame-rate will be unacceptable. SVSi recommends gigabit Ethernet networks whenever possible. The maximum distance between devices directly is 100 meters (328 feet) over CAT5/6 cable. This distance can be extended in 100 meters (328 feet) increments by using a gigabit switch as a repeater between devices. Copper to Fiber adapters can extend the maximum distance between devices up to 10km. The system is controllable through Conductor NetLite, N8001/N8002/N8012 Controllers, or a third-party control system using TCP/IP, such as Savant, Utelogy, AMX, Altinex, or Crestron. Successful implementation requires involvement of the facility IT administrator as soon as possible.

Once units are auto-discovered in NetLite, the CSV file can be exported into Excel where parameters such as IP address, subnet mask, gateway, stream number, audio settings, etc., can be configured. Once configured, importing this CSV file back into NetLite will assign those parameters to the appropriate device and reboot the device to activate. This procedure can be used to configure multiple Networked AV devices at the same time. It can also provide valuable diagnostics by allowing the user to see how NetLite thinks the device is configured.

5 Conductor NetLite, N8001, N8002 and N8012 Controllers Conductor Lite and Conductor Pro are network management software packages that install and run on a host machine. The host machine must be connected to the network containing the SVSi equipment. The N8000 Controller is a dedicated hardware device that simplifies set-up and allows expanded web-based control. All can be used to control a video network.

6 Although extensive video networks can be constructed using the Networked AV plug-and-play capabilities without Conductor software or a hardware controller, the following tasks can be accomplished only through the software: Manage multiple video streams down one cable Upload LocalPlay, HostPlay, and EMCast locally-stored content View a graphical presentation of video network connections Turn audio on and off Turn encoders on and off Switch any display from one video stream to another Switch between live video stream and locally-stored LocalPlay, HostPlay, or EMCast content Adjust variable bit-rate for each video stream Assign fixed IP addresses for each component Record and playback from N6123 or N6223 Networked Video Recorders Schedule tasks to be performed over the video network Address remote devices through the bi-directional RS232 control interface Provide LAN diagnostics The following table lists the host PC requirements for installing Conductor NetLite: Table 1 - System Requirements for Conductor NetLite Software Operating System RAM Network Connection Hard Disk Space Windows XP/Vista/7/8 or Mac OSX 512 MB minimum, 1GB recommended Ethernet (1000-baseT recommended) 100 MB 2 VIDEO INPUTS Analog or digital video is input directly to any encoder through the digital video input (DVI-I) connector. HDMI, Displayport, DVI-D, VGA, or component signals can be input using passive adapters or cables. HD-SDI, composite, or RF sources require digital conversion. 2.1 Supported Resolutions Each encoder samples the incoming digital video frequency and adjusts accordingly. The supported video resolutions are: Source Resolutions (width x height) Supported Frame-rate Computer Modes Up to 1600x Hz for all modes TV Modes Up to 1080p up to 60-Hz for all modes Note: 1080i is the only supported interlaced mode. Unscaled modes at resolutions above 720p are 30-Hz on the wire. If a video source gives the encoder a resolution that it does not support, a default screen will be displayed indicating nonsupported mode. Note that a particular monitor or TV may not support all of these modes. In this case, the display itself may default to its un-supported resolution screen. Both encoders and decoders have a scaling option that can be turned on or off. For seamless switching between video streams, all inputs should be scaled to the same resolution (720p60 is preferred). Decoder scaling set to native will bypass display scaling and present content at highest fidelity.

7 2.2 EDID Information Most video sources have the capability to output in multiple formats. The supported video resolutions and formats are stored in Extended Display Identification Data (EDID). Some video sources will query the attached display's EDID to assess supported resolutions and then output the highest common format. Other video sources will not query and instead start outputting in a pre-determined format. Each SVSi encoder acts like a display to a video source and comes pre-stored with a specific EDID indicating supported resolutions and formats. Conductor NetLite software allows an encoder to be loaded with the EDID from a particular display. This may be necessary to restrict the video source output format to only those supported by a particular monitor. Alternatively, enabling scaling on the encoder allows selection of a format that may be compatible with the display. See the operating manual for further information on setting EDID. 2.3 HDCP Copy protected content cannot be transmitted by SVSi's Networked AV products as shipped from the factory. Please contact SVSi if your video distribution requirements include fair-use or owner-created content. 3 NETWORK PROPERTIES Networked AV products use different network packet protocols for different operations. These network formats are described in the table below: Signal NetLite N8000 Series Controllers Default Address Range Comments Auto-discovery Broadcast Broadcast switchable but not routable not configurable, must add by MAC address Control (including serial) Video Audio TCP/IP Unicast TCP/IP Unicast xxx.xxx xxx.xxx xxx.xxx IP address settable in Conductor or N8000 controller administratively-scoped IP address switchable and routable with correct router configuration IGMP can be used for flood control administratively-scoped IP address switchable and routable with correct router configuration IGMP can be used for flood control Note: multi-cast addresses may be user-configured. Contact SVSi for configuration utility. These network protocols should be familiar to any network engineer. Because our Networked AV solutions bridge the gap between the audio-visual (AV) and information technology (IT) worlds, SVSi suggests involvement of both AV and IT departments in any installation. SVSi products are designed to be plug-and-play. The diagram below illustrates the basic installation of one encoder and one decoder. A video source provides the digital video content to the encoder which converts to Ethernet packets and sends to the attached decoder. The decoder reconstitutes the video with synchronized audio for presentation to the attached display. If high-fidelity video and audio are playing on the display in this simple configuration, the SVSi hardware is operating successfully. Source Decoder Display

8 The same system can be connected through a network as shown below. Network Source Decoder Display If the same decoder when connected through a network to the same encoder does not deliver high-fidelity video, a network problem exists. In most cases, the device IP addresses are incompatible with the existing network configuration. Contact your network administrator to determine network properties and configuration. More elaborate video networks can be constructed as illustrated below. Existing LAN Once configured using Conductor NetLite software, devices will remember their respective settings and will no longer be plugand-play. 3.1 IGMP and Routing Video Signals SVSi decoders, networked video recorders, and windowing processors support the internet group management protocol (IGMP) that allows video streams (groups) to be dynamically routed only to those ports requesting the video stream. The IGMP feature prevents the multi-cast video traffic from flooding the network and can significantly reduce traffic in a layer-3 network. Control signals are TCP/IP unicast and can be routed. Video signals, as described in the table, above are multi-cast and can be routed in certain cases. Many Cisco routers require that the routing table be pre-loaded so that the processor doesn't have to touch each packet to determine its destination. Pre-loading the routing table has been used successfully to route multi-cast video traffic. Alternatively, existing routing protocols like generic routing encapsulation (GRE) or equivalent can be used to route video traffic. These protocols generally encapsulate the multi-cast packets in unicast wrappers for point-to-point transmission between routers. Once at the intended unicast destination address, the unicast wrapper is stripped and packers revert to multi-cast. Although N1000 and N2000 encoders output only multi-cast video, N3000 encoders can output unicast video natively at a bandwidth compatible with lower speed links. N3000 also supports standard streaming protocols like RTP, RTSP, and HTTP Live commonly used with content delivery services.

9 3.2 Installation Over an Existing Network Heritage network equipment may or may not be fully gigabit enabled. Even though most appliances on a network are gigabit, it only takes one 100-baseT switch or router within the video pathway to degrade or block the signal completely. If you are unsure of your network appliances or configuration, contact your network administrator before trying to implement a Networked AV solution on your network. CAT 5/6 Fiber Managed Switch Managed Switch Managed Switch VLAN Voice/Data VLAN Voice/Data VLAN Voice/Data Even if a particular network is gigabit enabled, installing Networked AV components can cause excessive amounts of video packets to overwhelm a network segment, VLAN, or appliance depending on the background traffic level. This can adversely affect other users on the network and must be avoided. Contact your network administrator before installation to determine traffic levels. Conductor NetLite software allows each encoder's video stream to be turned off before connecting to an existing network. Once connected, encoders can be turned on one at a time to determine network impact. SVSi strongly recommends that all encoders be turned off and variable bit-rates set as low as possible before connecting to an existing network. The diagram above illustrates how Networked AV products can be installed on an existing layer-2 network over a dedicated VLAN separate from voice and data traffic while using an organization's existing infrastructure. The following steps can be taken (at the discretion of your network administrator) to facilitate integration with an existing network: Remove Flow Control and/or Storm Control on any network port passing the video stream. Enable IGMP query and snooping on all supported network switches. Enable VLANs to separate video traffic from data and voice. Allow multi-cast traffic on all network ports through which video streams pass. Reduce the variable bit-rate for each video stream in NetLite to obtain the lowest bandwidth at acceptable video quality. Reduce frame-rate 2x in NetLite software Turn all encoders off in NetLite when not in use. s can be scheduled to turn on and off within the software. Upload slide-show content to LocalPlay and display this locally-stored content when possible. Manually enter devices by mac address to prevent NetLite from sending out broadcasts to locate. For a large number of devices during setup, a CSV file of the format below can be imported into NetLite. Any or all of these items can help integrate your video onto an existing network.

10 3.2.1 Network Diagnostic Utilities SVSi offer free network utilities to facilitate this deployment. Our download site offers the following diagnostic tools available for free: Wireshark with an SVSi plug-in for extracting packet information from our Networked AV devices. This utility captures network packets to show source, destination, and payload. All multi-cast and broadcast packets will be captured and decoded. Wireshark does not require the host to have a compatible IP address. Viewer software this software runs on a host and automatically detects all Networked AV streams to allow selection from a drop-down list. Once selected, the video and audio streams are sampled directly from the network and played in a confidence window. This will allow encoder diagnostics in the event that video does not display. If Viewer shows the video and audio as good, encoder is working and decoder or network downstream of Viewer host is suspect. Viewer does not require the host to have a compatible IP address Networked AV Ping Test this Excel macro discovers devices on the video network and displays properties in a table. The host PC will need a compatible IP address in the same subnet as the Networked AV devices. NetLite software available for PC or Mac, this software provides a matrix presentation of all Networked AV devices color coded to indicate status. Red columns or rows indicate decoders or encoders, respectively, are non-communicative. Red text in a column indicates that a video source is not connected. Red text in a row indicates that a decoders display is not connected or not powered on. NetLite CSV output this comma-separated file identifies each device by mac and serial number along with IP address, stream number, audio status, etc. This file can be sorted by any parameter. 3.3 Installation Over a Dedicated Network Whenever possible, SVSi recommends a dedicated layer-3 network for transmitting video. We offer the Cisco SG300- and SG500- lines of pre-configured switches for resale to our partners. These switches are shipped pre-configured for Networked AV from the factory. Any network switch should have a backplane capacity at least (2 x 1000-Mbps x N) where N is the number of ports on the switch passing the video traffic. For example, a 24-port switch where all available ports may be used to pass video traffic should have a (2 x 1000 x 24) = 48-Gbps backplane. A single channel of N1000 video and up to ten channels of N2000 video can be sent or received from each port in this switch example although full bandwidth may not be used at any one time. Depending on N3000 encoder bandwidth settings, over 100 channels can be sent through one gigabit Ethernet port. It is possible to overwhelm a single switch port using IGMP when more than qty-10 N2000 or qty-1 N1000 decoders on the port request different video streams. When this happens, all video streams on the port will drop significant numbers of frames and appear jerky or cease to display video at all. This situation cannot be managed through the network except by reducing the bit-rates for all video streams where possible. Avoidance of more than a gigabit of traffic per wire during installation is the preferred method to prevent this occurrence.

11 The network diagnostic utilities of section can also be used for Networked AV systems deployed over physically separate dedicated networks. In many cases, the customer desires control of the AV system over the house network but doesn't want the multi-cast video traffic touching the house network. This is easily accomplished with an N8000-series controller. Dual IP addresses can be assigned to the controller one compatible with the house network and the other compatible with the AV network. The controller firewalls cross-over of video traffic onto the control network. 4 VIDEO OUTPUTS attached to the video network request certain video streams and convert the IP packets to synchronized video and audio for display. Digital video only is output through the DVI-D connector on each decoder. Balanced analog audio is available through the 5-pin Phoenix connector on the decoder or embedded digital audio is available through the DVI-D connector. Most decoder models have an IR transmitter and bi-dirctional serial port built-in for control of the display or third-party device co-located at the decoder. Please check your specific decoder model to make sure IR and serial control options are available. Each decoder (and encoder) have locally-stored splash-screens (LocalPlay) that can be commanded to play or will show in the event of network outage. When the network link goes down, this image will automatically play and can be used for diagnostics. Users can upload their own LocalPlay images and audio for digital signage when live video may not be needed. Up to 64 images can be stored in each N2000 device and a single splash-screen only for N1000 and N3000. SVSi's Networked AV IP format allows it to be integrated over copper, fiber, or wireless links with the appropriate network hardware. With IT support, high-definition video and audio can be streamed over common networks to be delivered when and where it's needed.
