CTN DM-NVX-370C DM NVX® 4K60 4:4:4 AV-over-IP Encoder/Decoder Card with HDMI® and USB-C® Connectivity

The DM‑NVX‑370C is a DM NVX® AV-over-IP encoder/decoder card that occupies one card slot in a DMF‑CI‑8 card chassis. The card is designed to function as either a transmitter or receiver. Capable of handling a network AV installation of any size, the DM‑NVX‑370C includes features such as secure web-based control and management, a scaling HDMI output, video wall processing, an analog audio input or output¹, native AES67 transmit and receive capability, support for copper and fiber Ethernet connectivity^2,3, and USB 2.0 and KVM (keyboard, video, and mouse) integration.

DM NVX System on Chip
The DM‑NVX‑370C is a first-generation endpoint that utilizes the DM NVX System on Chip (SoC). As a dedicated, purpose‑built chip, the SoC allows for a smaller form‑factor and more efficient heat dissipation than previous DM NVX system designs. The SoC is fully interoperable with all other DM NVX endpoints and maintains the Pixel Perfect Processing performance of the DM NVX AV-over-IP platform.

HDMI and USB-C 2x1 Input Switching
The DM‑NVX‑370C includes one HDMI® input and one USB‑C® input that comprise a 2x1 video switcher. Switching between the two inputs can be performed automatically using autoswitching mode, programmatically via a control system, or through the web interface. When mounted behind a conference room display device, the HDMI input provides a convenient way to connect a Crestron AirMedia® presentation gateway, video-conferencing codec, or small form factor computer. The USB‑C input allows for a DisplayPort™ Alt Mode video connection to laptops that do not feature an HDMI connection. The USB-C connector also enables bidirectional USB 2.0 data transfer between the host PC and local USB HID devices (or remote DM NVX and DM NUX endpoints) and supports up to 100 W of USB Power Delivery (PD) to the connected device.

eARC Support
The HDMI output of the DM‑NVX‑370C supports Enhanced Audio Return Channel (eARC) connectivity, enabling audio to be extracted from a connected display and transmitted over the network as a multichannel audio‑over‑IP (AoIP) stream. With eARC support, only a single cable is required for A/V input and audio output from the display. This also makes local audio content from the display (such as smart TV streaming applications) available to an AoIP audio distribution system.

The HDMI input supports eARC as an audio output to pass content from a multichannel AoIP stream to the HDMI output of a connected AVR. The multichannel stream generated by the DM NVX endpoint is also compatible with the DM‑NAX‑XSP (sold separately) for zones where video transmission is not required.

Real-Time 4K60 Video Distribution
DM NVX technology ensures real-time, full‑motion 4K60 video performance for presenting multimedia, videoconferencing, and live camera images. Interactive functions such as gameplay and using a mouse are fluid and natural. Line‑synchronized outputs ensure synchronization of content across multiple displays for applications such as digital signage and video walls. Variable Multicast Time-to-Live (TTL) support enables multicast traffic to traverse multiple routers.

Pixel Perfect Processing Technology
A DM NVX system incorporates Pixel Perfect Processing technology, which provides flawless video transport over the network. Depending on the operating mode, the DM‑NVX‑370C can encode or decode a video signal to achieve end-to-end latency of less than one frame. The image quality of the source is maintained across a 1 Gbps network at resolutions up to 4K60 4:4:4.⁴

Enterprise-Grade Security
A DM NVX system delivers a true enterprise-grade network AV solution that is engineering to fulfill demanding IT polices. Advanced security features and protocols that are supported include 802.1X authentication, Active Directory® credential management, AES-128 content encryption, PKI authentication, TLS, SSH, and HTTPS.

Encoder or Decoder Functionality
The DM‑NVX‑370C is configurable to operate as either a network AV encoder or decoder. As an encoder, the connected media source can be transmitted over the network to one or many decoders. As a decoder, the device feeds the received signal to a connected display device and can quickly switch between multiple encoder feeds. The operating mode can be reconfigured dynamically in less than one minute via a control system, web interface, or the DMF‑CI‑8 front panel.

HDMI Output with 4K60 4:4:4 Scaler
Whether configured as an encoder or decoder, 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.⁵

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.

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. In decoder mode, the DM‑NVX‑370C can receive both multichannel and 2-channel downmix signals from an encoder, allowing either signal to be selected at the HDMI output while the 2-channel signal is automatically routed to the analog output.

Audio Embedding or De‑embedding
AES67 support via native integration of Crestron DM NAX® audio-over-IP technology allows the selected audio source to be transmitted as a 2-channel AES67 source. Another AES67 2-channel audio stream can be received from another AES67 capable device or Crestron DM NAX device simultaneously and combined with the video signal.

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

An unbalanced stereo analog audio port is also included, which can be configured as either an input or output.¹

Copper and Fiber Ethernet Connectivity
The DM‑NVX‑370C includes two RJ‑45 1000BASE-T ports (Ethernet ports 1 and 2) and one SFP port (Ethernet port 3). Any Ethernet port can be used to transport video over a Gigabit Ethernet network. The ports can also be used to daisy chain multiple endpoints feeding a single-source video wall or individual displays that show the same video image.²

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 AV-over-IP Network Design Guide.

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 ports are provided on the DM‑NVX‑370C, allowing a USB mouse, keyboard, or other peripheral device to be paired with a computer or other host either at the local endpoint or a remote endpoint over the network.⁶

USB 2.0 Layer 3 data transport supports USB signal extension in DM NVX point-to-point applications across VLANs.

Streamlined Management Using a DM NVX Director Virtual Switching Appliance
For small to moderate-sized applications, a DM NVX endpoint network can be configured and controlled via a control system. For larger enterprise and campus‑wide signal routing applications, adding a DM NVX Director virtual switching appliance (DM‑NVX‑DIR‑ENT or DM‑NVX‑DIR2) enhances and streamlines the entire configuration and control process. A DM NVX Director appliance provides centralized management and enables creating multiple virtual matrix switchers through one easy‑to‑use web‑based portal.

Crestron XiO Cloud Service Support
