A reliable, high-performance AV over IP encoder that transports 4K60 4:2:0 and 4K30 4:4:4 video over standard Gigabit Ethernet with no perceptible latency or loss of quality. Supports HDCP 2.3 and provides a secure 4K signal routing solution for enterprise and campus-wide content distribution applications.

The DM-NVX-D20 is a compact AV-over-IP decoder designed to receive video with resolutions up to 4K60 4:2:0 over standard Gigabit Ethernet. Featuring secure web‑based control and management, an HDMI® output, an analog audio output, AES67 transmit and receive capability, and copper Ethernet connectivity with PoE support, the DM-NVX-D20 provides a decoder solution that offers price and performance optimization in a DM NVX network AV installation of any size.1, 2

Real-Time 4K60 Video Performance
Engineered for demanding conference room and classroom applications, the DM-NVX-D20 ensures real‑time, full‑motion 4K60 video performance for the presentation of multimedia, videoconferencing, and live camera images. Interactive functions such as gameplay and the use of a mouse are fluid and natural.

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

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.

Decoder Functionality
The DM-NVX-D20 provides decoder functionality designed for use with the DM-NVX-E20 or DM-NVX-E10 encoder. The DM-NVX-D20 supports resolutions up to 4K60 4:2:0 including 4K30 4:4:4. The DM-NVX-D20 receives a signal from the DM-NVX-E20 or DM-NVX-E10 and feeds it to a local display device via the HDMI output.

NOTE: In addition to the DM-NVX-E20 or DM-NVX-E10, the DM-NVX-D20 is also interoperable with other DM NVX products that can function as encoders. If the DM-NVX-D20 is used with a DM NVX encoder other than the DM-NVX-E20 or DM-NVX-E10, the stream type of the encoder must be configured to interoperate with the DM-NVX-D20. The resolution of the encoder must also be configured so that it does not exceed the maximum resolution of the DM-NVX-D20. Configuration of the encoder is accomplished by using the web interface or a control system.

It is recommended that the DM-NVX-D20 not be used with 4K60 4:4:4 encoders (for example, the DM-NVX-36x[C] Series) in order to maintain the higher resolutions supported by the 4K60 4:4:4 encoders.

NOTE: The HDMI output does not support video scaling.

Analog Audio De-embedding
The analog audio output provides a stereo line‑level signal to feed a local sound system or sound bar. The output volume can be adjusted by using the web interface or a control system.3

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 the selected audio 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 AES67 audio stream that is received can be combined with the video signal and then output via the HDMI output and analog audio output.

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

Copper Ethernet Connectivity
The DM-NVX-D20 includes one RJ-45 1000BASE‑T Ethernet port.2 The port is PoE compliant, enabling the device to be powered via a PoE Ethernet switch.4 For information about network requirements and guidelines, refer to the DM NVX AV-over-IP System Design Guide.

Automatic Point-to-Point Connectivity with the DM-NVX-E20 or DM-NVX-E10
Point-to-point connectivity enables the DM-NVX-D20 to be connected directly to a DM-NVX-E20 or DM-NVX-E10 to stream video and audio. Rather than being connected to an Ethernet switch, the 1000BASE-T Ethernet port of the DM-NVX-D20 is connected directly to the 1000BASE-T port of the encoder. By default, point-to-point mode automatically detects whether a DM-NVX-D20 is connected directly to the encoder or to a 1000BASE-T switch. When a direct connection between the DM-NVX-D20 and the encoder 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.

Device Control via RS-232, IR, and CEC
The DM-NVX-D20 includes built‑in COM (RS‑232) and IR ports for control of devices under the management of a control system. Additional control capability is provided by CEC (Consumer Electronics Control) over the HDMI connection. Under the management of a control system, the DM-NVX-D20 can control the display device via CEC, 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-D20 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
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.

Compact, Surface-Mountable Design
The DM-NVX-D20 mounts conveniently to a flat surface or rack rail and fits easily behind a flat panel display, above a ceiling‑mounted projector, or inside an 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 or an optional power pack (sold separately).4
