4 Implementation Considerations volante is based on gigabit Ethernet protocol. Each device is a 3-port gigabit Ethernet switch. (Except for VRR-204 decoders) When devices are connected discretely, they form a dedicated gigabit LAN. Devices can be installed within an existing gigabit network and share that network s bandwidth. Installation can incorporate any off-the-shelf gigabit Ethernet device into the video LAN. Products can incorporate any off-the-shelf 10/100-baseT device but video traffic must be blocked from going into the network port to which the device is connected. This can be done in Conductor software Each video stream is user-adjustable between Mbps depending on resolution and video content. Video 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-rates 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 or Server software, DiVAS, VDT111 or a thirdparty control system using TCP/IP, such as AMX, Altinex, Extron or Crestron. Using the VDT111 Practically any Third Party Control system can be utilized. Successful implementation requires involvement of the facility IT administrator as soon as possible. Signal Formats Control and video signal formats for volante devices are shown in the table below.

The host machine must be connected to the network containing the SVSi equipment. DiVAS is a stand-alone 1RU device that simplifies set-up and allows expanded web-based control. All can be used to control a video network. The following table lists features of each.

6 Video Inputs 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 before input to a encoder. Supported Resolutions Each encoder samples the incoming digital video frequency and adjusts accordingly. The supported video resolutions are: 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: all video formats with a pixel rate higher than 720p@60Hz are limited to 30-Hz on the wire. For these modes, the decoder plays each frame twice to achieve 60-Hz frame-rates. If a video source gives the encoder a resolution that it does not support, a default screen will be displayed indicating non-supported 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. 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 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. See the operating manual for further information on setting EDID. volante does not scale either inputs or outputs so that a common resolution must be used for deployments with varying display resolutions. HDCP Copy protected content cannot be transmitted by SVSi encoders as received from the factory. However, if the end-user has authority and license from the content provider to distribute copy-protected media across the video distribution system, digitally signing the End User License Agreement (EULA) enables the HDCP-capable feature of volante and allows copy protected content to be distributed. This is a one-time set-up feature upon configuration. SVSi fully supports the rights of content creators to protect their intellectual property and explicitly condemns use of its equipment to distribute content without proper approval.

7 Network Properties volante uses different network packet protocols for different operations. These network formats are described in the table below: Signal Conductor DiVAS Default Address Range Comments Auto-discovery UDP/IP Broadcast UDP/IP Broadcast switchable but not routable -not configurable, must add by MAC address Control (including serial) TCP/IP Unicast UDP/IP Unicast TCP/IP Unicast UDP/IP Unicast xxx.xxx -IP address settable in Conductor or DiVAS -IP broadcast reset for unreachable IP addresses -switching commands are UDP all other control TCP Video UDP/IP Multicast UDP/IP Multicast xxx -administratively-scoped IP address -switchable and routable with correct router configuration -IGMP can be used for flood control Audio UDP/IP Multicast UDP/IP Multicast xxx -administratively-scoped IP address -switchable and routable with correct router configuration -IGMP can be used for flood control These network protocols should be familiar to any network engineer. Because volante bridges 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. The same system can be connected through a network as shown below. If the same decoder when connected through a network to the same encoder does not deliver high-fidelity video, a network problem exists. This cannot be solved with SVSi hardware or software. Contact your network administrator to determine network properties and configuration. More elaborate video networks can be constructed as illustrated below.

8 Once configured using Conductor software, the system will remember these settings and will no longer be plugand-play. IGMP and Routing Video Signals SVSi decoders and the Viewer software both support the internet group management protocol (IGMP) that allows video streams (groups) to be dropped or subscribed upon passage through a network switch. The IGMP feature can significantly reduce network traffic if the network infrastructure supports IGMP queries. Control signals are TCP/IP unicast and can be routed. Video signals, as described in the table above are multicast and cannot be routed directly. 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. 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 volante on your network.

9 Even if a particular network is gigabit enabled, installing volante 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. The Conductor 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 below illustrates how SVSi can be installed on a dedicated VLAN and travel over an organization's existing network infrastructure separate from voice and data traffic. The following things can be done (at the discretion of your network administrator) to facilitate integration with an existing network: ü Remove Flow Control and/or Storm Control on any network port passing the video stream. ü Enable IGMP-query on layer-3 switches and IGMP-snooping on layer-2 ü Enable VLANs on layer-2 switches to separate video traffic from data and voice. ü Allow broadcast and multi-cast traffic on all network ports through which video streams pass. ü Reduce the variable bit-rate for each video stream in Conductor to obtain the lowest bandwidth at acceptable video quality. ü Reduce frame-rate 2x in Conductor software ü Turn all encoders off in Conductor when not in use. Encoders can be scheduled to turn on and off within

10 the software. ü Upload slide-show content to LocalPlay and display this locally-stored content when possible. ü Manually enter IP addresses, MAC numbers, and descriptions of all SVSi devices into the rx.txt, tx.txt, and dvr.txt files to prevent Conductor from sending out broadcasts to locate. Any or all of these items can help integrate your video onto an existing network. Installation Over a Dedicated Network Whenever possible, SVSi recommends a physically dedicated network for transmitting video. Network switches should be gigabit Ethernet with IGMP. The Cisco 3750, Dell 6224, or equivalent family of managed network switches are preferred. 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. Up to ten channels of video can be sent or received from each port in this switch example although full bandwidth may not be used at any one time. It is possible to overwhelm a single switch port using IGMP when more than ten decoders on that port request different video streams. When this happens, all video streams on that port will drop significant numbers of frames and appear still or jerky. This situation cannot be managed through the network except by reducing the bit-rates for all video streams involved. Avoidance of more than 10 streams down one wire during installation is the preferred method to prevent this occurrence. SVSi volante's 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.
