Interactive functions such as gameplay and the use of a mouse are fluid and natural.

      A DM NVX system is engineered for stability and reliability. Line-synchronized outputs ensure perfect synchronization of content across multiple displays for applications such as digital signage and video walls. Variable Multicast TTL (Time To Live) enables traversing multiple network routers for optimal flexibility.

      Pixel Perfect Processing Technology
      A DM NVX system incorporates Pixel Perfect Processing technology, which provides flawless video transport in all applications. Depending on the operating mode, the DM-NVX-351 can encode or decode a video signal to achieve imperceptible end-to-end latency of less than 1 frame. The image quality of the source is maintained across a 1-Gigabit network at any resolution up to 4K60 4:4:4.

      Enterprise-Grade Security
      Using advanced security features and protocols such as 802.1X authentication, Active Directory® credential management, AES-128 content encryption, PKI authentication, TLS, SSH, and HTTPS, a DM NVX system delivers a true enterprise-grade network AV solution engineered to fulfill demanding IT policies.

      Encoder or Decoder Functionality
      The DM-NVX-351 is configurable to operate as either a network AV encoder or decoder:

      As an encoder, the DM-NVX-351 allows the HDMI signal of a laptop computer, camera, or other media source to be transmitted over the network to one or many decoders.1
      As a decoder, the DM-NVX-351 receives the signal from a DM NVX encoder and feeds it to a display device via the HDMI output. The decoder can quickly and easily switch between multiple encoders on the network alongside locally connected HDMI sources.1
      The DM-NVX-351 provides a versatile, cost-effective solution for applications that require encoder and decoder operating modes in a single device. The operating mode can be reconfigured dynamically in less than 1 minute via a control system or web browser or can be changed by using the onboard Setup button.

      Auto-Switching HDMI® Inputs
      The DM-NVX-351 includes two HDMI inputs. Switching between the two inputs can be performed automatically using auto-switching mode, programmatically via a control system, manually using the onboard Input Select button, or through a computer using a web browser. When used as a decoder mounted behind a typical conference room display device, the HDMI inputs provide a convenient way to connect a Crestron AirMedia® presentation gateway, videoconferencing codec, or small form factor computer.1

      HDMI Output with 4K60 4:4:4 Scaler
      When the DM-NVX-351 is configured as a decoder, the HDMI output feeds the decoded signal to the HDMI input of a local display device, switcher, or other equipment. The built-in scaler ensures an optimal image, scaling the encoded source resolution up or down to match the native resolution of the display device. When the DM-NVX-351 is configured as an encoder, the HDMI output can be used to feed a local display, confidence monitor, or audio system.1, 4

      Video Wall Processing
      A video wall composed of up to 64 individual displays can be configured using multiple DM NVX endpoints. Each endpoint provides fully adjustable zoom capability and bezel compensation to accommodate a range of video wall configurations and display types. One DM NVX endpoint is required per display, supporting configurations of up to eight wide by eight high.

      The ability to display dynamic or fixed text on screen provides a means to label the video source or to display special instructions, schedules, announcements, alerts, and other messaging.

      Adaptive Bit Rate
      In DM NVX encoder mode, adaptive bit rate can be enabled or disabled using the web interface or a control system. Adaptive bit rate enables the encoder to automatically set the bit rate required for the input resolution of the stream; for example, the adaptive bit rate for a common resolution such as 1920x1080p@60Hz (1080p60) is automatically set to 400 Mbps. Adaptive bit rate makes better use of the available bandwidth.

      Analog Audio Embedding or De-embedding
      A balanced stereo analog audio port is included, which can be configured as either an input or output. As an input, the port allows a stereo audio source to be connected and combined with the video signal from either HDMI input or the incoming network video stream. As an output, the port can provide a stereo line-level signal to feed a local sound system or soundbar. The output volume is adjustable via a control system or web browser.5

      7.1 Surround Sound Audio with Downmixing
      DM NVX technology supports the lossless transport of 7.1 surround sound audio signals, including Dolby® TrueHD, Dolby Atmos®, DTS HD®, DTS:X®, and uncompressed linear PCM. The DM-NVX-351 can decode the incoming multichannel surround sound signal, whether from the network or an HDMI input, and downmix that signal to stereo. The stereo downmix signal is automatically routed to the onboard analog output5, while the HDMI output can be configured to output either stereo or multichannel signals. As an encoder, the DM-NVX-351 distributes both stereo and multichannel signals simultaneously over the network, allowing either signal to be selected at any decoder on the network.

      AES67 Audio Embedding or De-embedding
      AES67 support allows the selected audio source to be transmitted as a 2-channel AES67 source while another AES67 2-channel audio stream is received from a Crestron DSP or other third-party device and combined with the video signal.

      In DM NVX encoder mode, the received AES67 audio stream can be output via the local HDMI output, primary AV stream, secondary audio stream, and analog audio output. In DM NVX decoder mode, the received AES67 audio stream can be combined with the video and then output via the HDMI output and analog audio output.

      NOTE: An AES67 stream that is received by a DM NVX endpoint cannot be transmitted from that endpoint.

      Breakaway Audio
      A DM NVX decoder can select and combine separate video and audio signals from two different inputs—even two different encoders.6

      Copper and Fiber Ethernet Connectivity
      The DM-NVX-351 includes two RJ-45 1000BASE-T LAN ports (Ethernet ports 1 and 2) and one SFP port (Ethernet port 3). The SFP port enables connection to a fiber-optic network with the use of the appropriate Crestron SFP-1G Series transceiver module (sold separately). A selection of modules is offered to accommodate various multimode and single-mode fiber types.3

      Ethernet port 1, 2, or 3 can be used to transport video over a Gigabit Ethernet network. Ports 1 and 2 can also be used to provide network connections for an AirMedia gateway, display device, or other local device. In addition, the ports can be used to daisy-chain multiple endpoints feeding a single-source video wall or individual displays that show the same video image. Port 1 is also capable of receiving power from a Crestron power injector (DM-PSU-ULTRA-MIDSPAN), UPOE compliant Ethernet switch, or third-party IEEE 802.3bt compliant PSE.2, 7

      A DM NVX system can be deployed on an existing corporate or campus network or on a dedicated network. For information about network requirements and guidelines, refer to the DM NVX AV-over-IP System Design Guide, Doc. 7977.

      USB 2.0 and KVM Integration
      DM NVX technology supports the extension of USB signals, which can be switched and routed alongside the AV signal or separately via a control system. USB 2.0 HOST and DEVICE ports are provided on the DM-NVX-351, allowing a USB mouse, keyboard, or other peripheral device to be connected to a remote endpoint and routed to a computer or other host at the local endpoint. In addition to KVM switch functionality, various types of USB peripherals are supported, including whiteboards, touch screens, game controllers, cameras, mobile devices, headsets, and flash drives.8

      USB 2.0 data transport can be configured for Layer 2 or Layer 3. Layer 2 supports USB signal extension in point-to-point and multipoint applications. USB signals can be routed from the HOST port of up to seven remote DM NVX endpoints to the DEVICE port of a single local DM NVX endpoint. Layer 2 also supports Crestron USB over Ethernet Extender Modules (USB-EXT-DM-LOCAL or USB-EXT-DM-REMOTE), which can be used in locations that do not include DM NVX endpoints. USB signals can be routed between DM NVX and USB-EXT-DM devices under the management of a control system.9

      USB 2.0 Layer 3 data transport supports USB signal extension in DM NVX point-to-point applications across VLANs. USB-EXT-DM devices do not support Layer 3.

      Device Control
      The DM-NVX-351 includes built-in COM (RS-232) and IR ports for control of the connected display, camera, or other devices under the management of a control system. Additional control capability is provided by CEC (Consumer Electronics Control) over the HDMI connections. Under the management of a control system, the DM-NVX-351 can control the display and source devices, potentially eliminating the need for dedicated serial cables or IR emitters.

      The COM port, IR port, and CEC over the HDMI output can also enable the display device to be turned on or off automatically without the use of a control system.

      Web-Based Setup
      Setup of the DM-NVX-351 is accomplished by using a web browser. Full control and monitoring of the device is enabled through integration with a control system or with a DM NVX Director™ virtual switching appliance.

      Streamlined Management Using DM NVX Director Virtual Switching Appliances
      For applications that are small to moderate in size, a network of DM NVX endpoints can be configured and controlled with the use of a control system. For larger enterprise and campus-wide signal routing applications, adding a DM NVX Director virtual switching appliance (DM-NVX-DIR-80, DM-NVX-DIR-160, or DM-NVX-DIR-ENT) enhances and streamlines the entire configuration and control process. A DM NVX Director appliance provides a central point of management and enables the creation of multiple virtual matrix switchers through one easy-to-use web-based portal.

      Crestron XiO Cloud® Service Support
      The DM-NVX-351 is compatible with the Crestron XiO Cloud service, which is a platform for remotely provisioning, monitoring, and managing Crestron devices across an enterprise or an entire client base. The service enables installers and IT managers to deploy and manage thousands of devices in the amount of time it previously took to manage a single device.
