Using 802.1X authentication, Active Directory® credential management, AES-128 content encryption, PKI authentication, TLS, SSH, and HTTPS, a DM NVX system provides a true enterprise-grade network AV solution engineered to fulfill demanding IT policies.

Encoder Functionality
The DM-NVX-E760 is an encoder that is compatible with DM NVX products that can function as decoders. The DM-NVX-E760 enables AV signals from the DM input to be transmitted over the network to one or many decoders. Encoder functionality of the DM-NVX-E760 can be used in any DM NVX network AV design.

Interoperability with DM 8G+ Output Devices and DM Lite Transmitters
The DM input of the DM-NVX-E760 can be connected to the DM 8G+ output of a DM switcher, transmitter, or other DM device. Supported DM 8G+ output devices are the DMC-4KZ-CO-HD and DMB-4K-O-C of DM switchers, the DM-TX-4KZ-100-C-1G transmitter, and the DMPS3-4K-350-C and DMPS3-4K-250-C presentation systems.

The DM input can also be connected to the DM Lite port of a DM Lite transmitter. Supported DM Lite transmitters are the HD-TX-101-C-E and the HD-TX-101-C-1G-E.

HDBaseT Certification
Crestron DM 8G+ technology of the DM input is designed using HDBaseT Alliance specifications, ensuring interoperability with other HDBaseT certified products. The DM input of the DM-NVX-E760 can be connected directly to an HDBaseT compliant source. The DM-NVX-E760 provides the capability to bridge an HDBaseT system with AV over IP, resulting in a hybrid system design and a smooth migration path for existing DM or HDBaseT solutions. Investment protection is achieved for applications that require integration of AV over IP with existing HDBaseT systems or expansion of an existing room system for broader distribution.

NOTE: The DM input will support Ethernet and control signals in a future release.

Image Preview
Image preview provides still images (thumbnails) that show the current video being received by the DM input of the DM-NVX-E760. Still images are shown at 1 frame per second. Image preview supports the maximum resolution of the source and scales the image while maintaining the aspect ratio. Images can be previewed in the DM NVX web interface and accessed remotely by using a web browser. The images can also be previewed on a Crestron touch screen or third-party interface.

Test Pattern Generator
The built-in test pattern generator can be used during setup to ensure that video streaming is functional and can also be used as a tool for the adjustment, calibration, and alignment of displays, projectors, and video walls. The DM-NVX-E760 can send the test pattern to any routed DM NVX decoder.

Fixed, Adaptive, or Variable Bit Rate
In DM NVX encoder mode, the bit rate of a stream can be set to fixed, adaptive, or variable:

  • A fixed bit rate, also referred to as Constant Bit Rate (CBR), is user specified and can be set to a value ranging from 200 Mbps to 950 Mbps.3
  • Adaptive bit rate (ABR) enables the encoder to automatically set a fixed bit rate based on the input resolution of the stream. For example, the adaptive bit rate for a common resolution such as 1920x1080p@60Hz (1080p60) would automatically be set to 400 Mbps. Adaptive bit rate makes better use of the available bandwidth than a user-specified fixed bit rate.
  • Variable bit rate (VBR) enables the encoder to automatically vary the bit rate based on the content and input resolution of the stream. The bit rate can vary from less than 150 Mbps to a maximum of 750 Mbps. A variable bit rate results in the use of less bandwidth to produce the same image quality as a user-specified fixed bit rate or an adaptive bit rate.

The web interface or a control system can be used to set a fixed bit rate or to enable adaptive or variable bit rate functionality.

Analog Audio De-embedding
The analog audio output provides a balanced or unbalanced stereo line level signal to feed a local sound system or sound bar. The output volume is adjustable using the web interface or a control system.4

7.1 Surround Sound Audio
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.

AES67 Audio Embedding and De-embedding
AES67 support enables an HDBaseT source to be transmitted as a 2-channel AES67 audio stream while another 2-channel AES67 audio stream is received from a Crestron DSP or other third-party device. The received AES67 audio stream can be output via the analog audio output.

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

Copper and Fiber Ethernet Connectivity
The DM-NVX-E760 includes two RJ-45 1000BASE T Ethernet 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-1GSeries transceiver module (sold separately). A selection of modules is offered to accommodate various multimode and single-mode fiber types.

Ethernet port 1, 2, or 3 can be used to transport video over a Gigabit Ethernet network. The remaining Ethernet ports can be used to provide connections to local network devices or to daisy-chain multiple endpoints.

Ethernet port 1 is PoE++ and UPOE compliant and can be powered from PoE++ power sourcing equipment such as the Crestron DM-PSU-ULTRA-MIDSPAN (sold separately), a PoE++ or UPOE compliant Ethernet switch, or third-party compliant PSE.

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.

Network Port Selection
Network port selection enables network traffic to be managed and segregated based on traffic type. Internal VLANs are used to route different traffic types to specific external Ethernet ports, which can then be assigned to the various traffic types. AES67 audio can be separated from the primary video and control network resulting in a dedicated audio network.

Automatic Point-to-Point Connectivity
Point-to-point connectivity enables the DM-NVX-E760 to be connected directly to a DM NVX 4K60 4:4:4 decoder to stream video and audio. Rather than being connected to an Ethernet switch, a 1000BASE-T Ethernet port of the DM-NVX-E760 is connected directly to a 1000BASE-T port of a decoder.

By default, point-to-point mode automatically detects whether the DM-NVX-E760 is connected directly to a DM NVX 4K60 4:4:4 decoder or to a 1000BASE-T switch. When a direct connection between the DM-NVX-E760 and a decoder is detected, the devices operate in point-to-point mode without the need for additional configuration. The web interface or a control system can be used to disable point-to-point mode or to enable automatic detection of point-to-point connectivity.

Web-Based Setup
Setup of the DM-NVX-E760 is accomplished by using the built‑in web interface. 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
Use of a DM NVX Director virtual switching appliance (DM-NVX-DIR-80, DM-NVX-DIR-160, or DM-NVX-DIR-ENT) 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.

Low-Profile Installation
The DM-NVX-E760 mounts conveniently to a flat surface or rack rail and fits easily beneath a tabletop or inside a lectern, AV cart, or equipment cabinet. All connectors and LED indicators are positioned on the front and rear of the device, offering optimal access and visibility for a clean, serviceable installation. Power is provided via PoE++, UPOE, or the included PW-2420RU power pack.
