📋Product Description

The Crestron DM-NVX-351 is a compact and versatile AV over IP encoder/decoder designed to transport 4K Ultra HD video with a resolution of up to 4096x2160 at 60 Hz, 4:4:4 color sampling, and HDR10 support over a standard Gigabit Ethernet network. With patented DigitalMedia NVX technology using optimized JPEG 2000 encoding, this device offers exceptionally low end-to-end latency of only 30 milliseconds, ensuring smooth and real-time video performance for conferencing, video conferencing, multimedia presentations, and live content broadcasting applications.

The DM-NVX-351 unit can be dynamically configured to operate either as an encoder or a decoder, offering maximum flexibility in professional AV installations. In encoder mode, it allows for the connection of HDMI sources such as laptops, cameras, or media players and distributes them over the network. In decoder mode, it receives video streams from the network and transmits them to displays via its HDMI output. This bidirectional capability enables the creation of scalable and cost-effective AV switching and distribution solutions for installations of all sizes.

The DM-NVX-351 model includes all the features of the DM-NVX-350 with the crucial addition of the audio downmixing function, allowing for the decoding of a 7.1 multichannel surround audio signal and converting it to stereo. This feature is essential for installations requiring the simultaneous distribution of surround and stereo audio content to different receiving points.

❓Frequently Asked Questions (FAQ)

Q1: How does DM NVX technology work for 4K video distribution over standard Ethernet?
Crestron's DigitalMedia NVX technology uses highly optimized JPEG 2000 encoding with a patented technique that overlays scaling and encoding latencies. This approach allows for the transport of 4K60 4:4:4 video with HDR10 support over a standard Gigabit Ethernet infrastructure without requiring specialized cabling or dedicated AV switches. The video stream is encapsulated in standard IP packets using RTP and RTSP protocols, enabling distribution over existing LAN networks. JPEG 2000 compression offers an excellent balance between "pixel perfect" visual quality and network bandwidth, while maintaining an exceptionally low end-to-end latency of 30 milliseconds at 60 frames per second. This low latency is crucial for interactive applications such as mouse control, gaming, or live presentations. The system supports RTSP multicast to efficiently stream the same content to multiple decoders simultaneously without overloading the network.
Q2: Can we dynamically switch between encoder and decoder mode, and what are the advantages of this flexibility?
Yes, the DM-NVX-351 can dynamically switch between encoder and decoder modes via programmatic commands from a Crestron control system or through the web configuration interface. This bidirectional capability offers several major advantages for professional AV installations. In a conference room, the same unit can function as a decoder to display the main content on the screen, then switch to encoder mode to share the local content of a presenter to other rooms. This flexibility significantly reduces equipment costs by eliminating the need for separate encoders and decoders in each space. For multi-room installations, it allows for dynamic configurations where any room can become a source or destination as needed. The two auto-switching HDMI inputs also allow for the simultaneous connection of local sources and an AirMedia gateway for wireless sharing, providing a complete presentation solution in a single compact unit.
Q3: What is the specificity of the audio downmixing of the DM-NVX-351 compared to the DM-NVX-350 model?
The DM-NVX-351 differs from the DM-NVX-350 model by the addition of a surround audio downmixing capability to stereo. Specifically, when the unit receives a 7.1 multichannel audio signal (whether from a local HDMI input or over the network), it can decode this signal and automatically convert it to stereo 2.0. The mixed stereo signal is automatically routed to the device's analog audio output, while the HDMI output can be configured to deliver either the stereo signal or the full multichannel surround signal. In encoder mode, the DM-NVX-351 simultaneously distributes both versions (stereo and surround) over the network, allowing each decoder to select the appropriate audio version according to its playback capabilities. This feature is essential in environments where some areas have full surround audio installations while others only have stereo speakers. It ensures universal audio compatibility without compromising quality for systems capable of reproducing Dolby Atmos surround sound, DTS:X, or other advanced immersive formats.
Q4: What are the network prerequisites and security protocols supported by the DM-NVX-351?
The DM-NVX-351 requires a Gigabit Ethernet (1000 Mbps) network infrastructure to ensure smooth 4K60 transmission. For deployments on a shared network, managed switches supporting IGMPv2 for multicast and QoS (Quality of Service) are recommended to prioritize AV traffic. In terms of security, the device incorporates enterprise-class features required by corporate, academic, medical, and government environments: 802.1x network authentication to control device access, Active Directory integration with centralized credential management, PKI (Public Key Infrastructure) with digital certificates, AES-128 encryption to protect video streams, secure protocols TLS, SSH, HTTPS, and SFTP for all management communications. The system can operate on an isolated dedicated AV network or be integrated into the corporate LAN with appropriate access controls. HDCP 2.2 compliance ensures the protection of premium content against unauthorized copying. These security features enable the DM-NVX-351 to meet strict IT policies while preserving the integrity of the broadcast content and the confidentiality of presentation sessions.
Q5: How to configure and manage the DM-NVX-351, and is a Crestron control system necessarily required?
The initial setup of the DM-NVX-351 is easily done via its built-in web interface accessible from any browser by connecting to the device's IP address. This interface allows you to define network settings, select encoder or decoder mode, configure video resolutions, manage audio settings, and monitor system status. For standalone or small installations, a Crestron control system is not mandatory - switching between sources can be done manually via the built-in selection button or through the web interface. However, to fully leverage the advanced capabilities of the device in complex multi-room installations, integration with a Crestron control processor (CP4, CP4N, RMC4, etc.) is highly recommended. The control system enables automation of scenarios, dynamic encoder/decoder switching, sophisticated audio/video routing, centralized management of multiple units, and integration with other AV equipment. The DM-NVX-351 also supports SNMP monitoring for integration with enterprise network monitoring systems and ONVIF for interoperability with standardized video management platforms.
Q6: What are the advanced video processing capabilities like video wall and text overlay?
The DM-NVX-351 integrates an embedded video processing engine offering several advanced features without requiring external hardware. The video wall function allows for the creation of video walls by configuring each decoder to display a specific portion of a larger source image, supporting configurations of up to 8 screens wide by 8 screens high. The system automatically manages image cropping, bezel compensation, and pixel-perfect synchronization between all screens. The built-in 4K60 4:4:4 scaling allows any source resolution to be adapted to the native resolution of the destination screens without loss of quality. The text overlay function enables dynamic text insertion on video streams, useful for displaying contextual information, subtitles, alerts, or room identifications in digital signage systems. These processing capabilities occur in real-time without impacting latency, preserving the fluidity necessary for interactive applications. For installations requiring USB and KVM extension, keyboard/mouse signal routing follows video routing, allowing remote control of source computers from any decoding point on the network.
