Real-time 4K video distribution

Engineered for demanding conference room and classroom applications, DM NVX ensures real-time, full-motion 4K video performance for the presentation of multimedia, videoconferencing, and live camera images. DM NVX employs high-quality JPEG 2000 encoding using an advanced 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.

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, programmatically via a Crestron control system, or through a computer using a web browser.

HDMI output

When configured as a decoder, the DM-NVX-351's HDMI output feeds the decoded signal to the input of a switcher, a 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.

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 card, allowing a USB mouse, keyboard, or other device to be connected at one DM NVX endpoint and routed to a computer or other host at any other endpoint. 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.

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, 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 analog audio switcher. The output volume is adjustable via a control system or web browser.
