Using standard network switches and CAT5e UTP wiring, a DM NVX system delivers a high‑performance virtual matrix routing solution for any enterprise or campus‑wide 4K content distribution application. Support for HDR (High Dynamic Range) and HDCP 2.3 compliance ensures the ultimate in picture quality and compatibility for all of today’s varied media sources.1, 2
The DM‑NVX‑D30C is an AV over IP decoder that occupies one slot of a DMF‑CI‑8 card chassis. The card is designed to function as a receiver in a high‑density rack‑mount installation. Featuring secure web‑based control and management, an HDMI® output, an analog audio output, AES67 transmit and receive capability, and copper Ethernet connectivity, the DM‑NVX‑D30C offers a decoder solution for a DM NVX network AV installation of any size.2
Real‑Time 4K60 Video Distribution
Engineered for demanding conference room and classroom applications, DM NVX technology 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.
Pixel Perfect Processing Technology
A DM NVX system incorporates Pixel Perfect Processing technology, which provides flawless video transport in all applications. The DM‑NVX‑D30C can decode a video signal to achieve imperceptible end‑to‑end latency of less than 1 frame. The image quality of the source is maintained across a 1‑Gigabit network at any resolution up to 4K60 4:4:4.
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.
The DM‑NVX‑D30C is a basic decoder card that receives a signal from a DM NVX encoder and feeds it to a local display device via the HDMI output. The DM‑NVX‑D30C can quickly and easily switch among multiple encoders on the network. Compatible with DM NVX products that can function as encoders, the DM‑NVX‑D30C can be used in any DM NVX network AV design.
NOTE: The HDMI output does not support video scaling.
Image preview provides still images (thumbnails) that show the current video being displayed by an output of a DM NVX decoder. Still images are shown at one 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 using a web browser. The images can also be previewed on a Crestron touch screen or third-party interface.
Background Image for On-Screen Display
An image can be uploaded to the DM-NVX-D30C for use as a background image on a display whenever active video content is not being displayed. Supported image file types are .jpeg, ,jpg,, and .png. The supported maximum resolution of an image is 3840x2160 pixels. Up to 20 image files can be uploaded for a total storage capacity of up to 100 MB.
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 is adjustable via a control system or web browser.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 and combined with the video signal. The received AES67 audio stream can be combined with the video 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‑D30C includes one RJ-45 1000BASE‑T Ethernet port.2 For information about network requirements and guidelines, refer to the DM NVX AV-over-IP System Design Guide, Doc. 7977.
Automatic Point-to-Point Connectivity
Point-to-point connectivity enables the DM-NVX-D30C to be connected directly to a DM NVX 4K60 4:4:4 encoder to stream video and audio. Rather than being connected to an Ethernet switch, the 1000BASE-T Ethernet port of the decoder is connected directly to a 1000BASE-T port of an encoder.
By default, point-to-point mode automatically detects whether the DM-NVX-D30C is connected directly to a DM
NVX 4K60 4:4:4 encoder or to a 1000BASE-T switch. When a direct connection between the DM-NVX-D30C and an encoder is detected, the devices operate in point-to-point mode without the need for additional configuration; however, a control system is required for CEC (Consumer Electronics Control).
CEC Device Control
Under the management of a control system, the DM‑NVX‑D30C can control the display device via CEC over the HDMI connection, potentially eliminating the need for dedicated serial cables or IR emitters.
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.
Setup of the DM‑NVX‑D30C is accomplished by using a web browser. Full control and monitoring of the card 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
For applications that are small to moderate in size, a network of DM NVX endpoints can be configured and controlled with the use of a control system. For larger enterprise and campus‑wide signal routing applications, adding a DM NVX Director virtual switching appliance (DM-NVX-DIR-80, DM-NVX-DIR-160, or DM-NVX-DIR-ENT) enhances and 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.
High‑Density Card‑Based Solution
The DM‑NVX‑D30C is designed for installation into a DMF‑CI‑8 card chassis, which provides a high‑density solution for applications requiring multiple encoders and decoders in one equipment rack.
