Crestron Electronics, Inc - DM-NVX-351

DigitalMedia™ NVX technology transports ultra high-definition 4K video with 60 Hz frame rates and 4:4:4 color sampling over standard Gigabit Ethernet. Support for HDR video (HDR10) and HDCP 2.2 ensures the ultimate in picture quality and compatibility for all of today’s varied media sources. Using standards-based Ethernet wiring and switches, DM® NVX delivers a vastly scalable, high-performance solution for enterprise-wide 4K content distribution.

The Crestron® DM-NVX-351 is a compact video encoder/decoder designed to function as either a transmitter or receiver with the ability to switch between the two modes programmatically via commands from a Crestron control system. Featuring simple web-based control and management, USB and KVM integration, and support for copper and fiber LAN connectivity, the DM-NVX-351 offers a one-stop solution for any-sized network AV installation.

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 using a patent-pending technique that overlaps scaling and encoding latencies, achieving an ultra-low end-to-end latency of 30 ms at 60 fps, so on-screen functions such as mousing and game play are fluid and natural.

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.
• 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.
• The encoder/decoder mode can be switched on-the-fly via a control system to provide a versatile, cost-effective presentation switching solution using one integrated device.

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.

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.
