More Details


DigitalMedia™ NVX technology transports ultra high-definition 4K60 4:4:4 video over standard Gigabit Ethernet with no perceptible latency or loss of quality. Leveraging standard network switches and CAT5e UTP wiring, DM® NVX delivers a rock-solid, high-performance virtual matrix routing solution that is both economically advantageous and infinitely scalable for any enterprise or campus-wide 4K content distribution application. Professional onboard scaling, plus support for HDR10 and HDCP 2.2, ensures the ultimate in picture quality and compatibility for all of today’s varied media sources.[1,2]

The Crestron® DM-NVX-351 is a compact AV over IP encoder/decoder designed to function as either a transmitter or receiver. Featuring simple, secure web-based control and management, auto-switching HDMI® inputs and output, analog audio in or out, USB and KVM integration, video wall processing, and support for copper and fiber LAN connectivity, the DM-NVX-351 offers a one-stop solution for any-sized network AV installation.[2,3]

The DM-NVX-351 includes all the features of the DM-NVX-350 with the addition of surround sound to stereo downmixing. Refer to the “7.1 Surround Sound Audio with Downmixing” section below for details.

Real-Time 4K60 Video Distribution
Engineered for demanding conference room and classroom applications, DM NVX ensures real-time, full-motion 4K60 video performance for the presentation of multimedia, videoconferencing, and live camera images. DM NVX employs high-quality JPEG 2000 encoding and decoding using a patent-pending technique that decodes and scales simultaneously to achieve imperceptible end-to-end latency of just 25 ms or less (1.5 frames). With DM NVX, interactive functions such as mousing and game play are fluid and natural.

DM NVX is engineered for rock-solid stability and ultimate reliability. Forward Error Correction is employed to ensure that AV data is delivered without interruption regardless of interference around the network cable. Line-synchronized outputs ensure perfect synchronization of content across multiple displays for one-to-many applications such as digital signage or video walls. Variable Multicast TTL (Time To Live) enables traversing multiple network routers for optimal flexibility.

Encoder and Decoder in One
In a single compact device, the DM-NVX-351 is configurable to operate as either a network AV encoder or decoder.

  • As an encoder, it allows a laptop computer, camera, or other media source to be connected via HDMI and then transmitted over the network to one or many decoders.[1]
  • As a decoder, it receives the signal from a DM NVX encoder and feeds it to a display device via the HDMI output. It can quickly and easily switch between multiple encoders on the network alongside locally-connected HDMI sources.[1]
  • The encoder/decoder mode can be reconfigured dynamically in under one minute via a control system or web browser, or using the onboard Setup button, offering a versatile, cost-effective solution for applications that require both modes in one box.

2x1 HDMI® Auto-Switcher
The DM-NVX-351 includes two HDMI inputs. Switching between the two inputs can be performed automatically using auto-switching mode, manually using the onboard input select button, programmatically via a Crestron control system, 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 mini computer.[1]

HDMI Output
When configured as a decoder, the DM-NVX-351’s HDMI output feeds the decoded signal to the local display device (or any other device with an HDMI input). Its 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 used as an encoder, the HDMI output can be used to feed a local display, confidence monitor, or audio system.[1,4]

USB and KVM Integration
For a complete signal management solution, DM NVX supports the extension of USB signals, which may be switched and routed alongside the AV signal or separately via the control system. USB 2.0 host and device ports are provided on each DM-NVX-351 box, allowing a USB mouse, keyboard, or other device to be connected at one box and routed to a computer or other host at another box. KVM switch functionality is a natural application for this feature, but all types of USB peripherals are supported including whiteboards, touch screens, game controllers, cameras, mobile devices, headsets, and flash drives.[5]

USB signals can also be routed to other locations where a DM NVX box does not exist using Crestron USB over Ethernet Extender Modules (USB-EXT-DM-LOCAL or USB-EXT-DM-REMOTE). USB signals can be freely routed between DM NVX and USB-EXT-DM units over Ethernet under the management of a Crestron control system.[6]

7.1 Surround Sound Audio with Downmixing
DM NVX 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 includes the ability to 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 output [7], while the HDMI output can be configured to output either stereo or multichannel. 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.

Analog Audio Embedding or De-embedding
A balanced stereo analog audio port is included, which may be configured as either an input or output. As an input, it 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, it can provide a stereo line-level signal to feed a local sound system or sound bar. The output volume is adjustable via a control system or web browser.[7]

Breakaway Audio
A DM NVX decoder may select and combine separate video and audio signals from two different inputs, even two different encoders. There are just two exceptions: A) signals may not be combined between the two onboard HDMI inputs, and B) combining signals from two separate encoders is limited to 2-channel stereo audio.[8]

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

Video Wall Processing
A video wall composed of up to 64 individual displays can be configured using multiple DM-NVX-351 units. Each unit provides fully-adjustable zoom capability and bezel compensation to accommodate a range of video wall configurations and display types. One DM-NVX-351 is required per display, supporting configurations of up to eight wide by up to eight high.

Copper or Fiber LAN Connectivity
The DM-NVX-351 includes two RJ45 1000Base-T LAN ports. Either port may be used as the primary LAN connection, allowing the other to be used to provide a network connection for the display, AirMedia gateway, or other local device(s). These ports may also be used to daisy-chain multiple units feeding a single-source video wall or individual displays all showing the same video image. Port 1 is also capable of receiving power from a Crestron power injector (DM-PSU-ULTRA-MIDSPAN) or approved third-party PSE.[2,9]

Connection to a fiber optic network is facilitated by inserting an appropriate SFP transceiver module (Crestron SFP-1G series) into the SFP port on the DM-NVX-351. A selection of modules is offered to accommodate various multimode and single-mode fiber types.[3]

DM NVX can be deployed on an existing corporate or campus network or a dedicated network. The optimal choice depends on a number of considerations. For complete network requirements and guidelines, please refer to the DM NVX Application Design Guide and DigitalMedia NVX Series System Design Guide, Doc. 7977, both available at https://www.crestron.com/nvx.

Enterprise-Grade Security
A secure AV network ensures its own reliability by protecting the integrity of the content being delivered and the privacy of the personnel accessing it. Every device on the network must be secure to protect against malicious intrusions from both inside and outside of the LAN. Employing advanced security features and protocols like 802.1x authentication, Active Directory® credential management, AES content encryption, PKI authentication, TLS, SSH, and HTTPS, DM NVX delivers a true enterprise-grade network AV solution engineered to fulfill the demanding IT policies of corporate, university, medical, military, and governmental clients.

Device Controller
The DM-NVX-351 includes built-in RS-232 and IR control ports for control of the connected display, camera, and other devices under the management of a control system. Additional control capability is afforded by harnessing the CEC (Consumer Electronics Control) signal embedded in HDMI. Through its Ethernet connection to the control system, the DM-NVX-351 provides a gateway for controlling the display and source devices right through their HDMI connections, potentially eliminating the need for any dedicated serial cables or IR emitters.[10]

Web-Based Setup
Setup of the DM-NVX-351 is accomplished using a computer web browser. Full control and monitoring of the device is enabled through integration with a Crestron control system.

DM XiO Director Option
For small to moderate sized applications, a network of DM NVX endpoints can be configured and controlled using a Crestron control system. For larger enterprise and campus-wide signal routing applications, adding the DM XiO Director (DM-XIO-DIR-80, DM-XIO-DIR-160, or DM-XIO-DIR-ENT) enhances and streamlines the entire configuration and control process by providing a central point of management, and by enabling the creation of multiple virtual matrix switchers, all through one easy-to-use web-based portal.

Low-Profile Installation
The DM-NVX-351 mounts conveniently to a flat surface or rack rail, and fits easily behind a flat panel display, above a ceiling-mounted projector, beneath a tabletop, or inside a lectern, AV cart, or equipment cabinet. All connections and LED indicators are positioned on the top and bottom, offering optimal access and visibility for a clean, serviceable installation. Power is provided using the included 100-240V universal power pack, an optional power injector (Crestron DM-PSU-ULTRA-MIDSPAN), or an approved third-party PSE.[9]
