MMG D:ONE is a compact NDI® and USB media player with an HDMI output. It receives any NDI® source on your network and puts it on a screen, shows four sources at once in a quad multiview, plays video and stills from a USB drive, or runs beat-reactive audio visuals — all managed from a browser.

Does MMG D:ONE support 4K?

Yes. The HDMI output drives whatever the connected display advertises, up to 4K at 60fps. NDI®|HX (HEVC) sources are decoded on the device's dedicated video block and passed straight to the display on a zero-copy path, at 4K 60fps. Full-bandwidth NDI® (SpeedHQ) is decoded in software and handles 1080p and 4K at 30fps. Video played from a USB drive is decoded in software and is supported up to 1080p.

How do you set up an MMG D:ONE?

Power it on and it raises its own WiFi hotspot and shows a scan-to-join QR code on the display. Scan the code with your phone, join the network, and you land straight in the device's web interface — no laptop or prior network configuration required. The QR code clears itself as soon as you choose something to play.

Can MMG D:ONE show more than one NDI source at a time?

Yes. Quad multiview shows four NDI® sources on one screen. You choose which of the four you hear, drag them into any order, and promote any quadrant to full screen instantly. The four quad streams run in the efficient proxy tier to keep network use low, which makes it ideal for monitoring.

Can you manage several MMG D:ONE units together?

Yes. Units discover each other on the network automatically, and any one of them can drive the rest — there is no central server to run and nothing in the cloud. Control travels over an encrypted mutual-TLS channel, and a device only joins a fleet once you approve the six-digit code shown on its own screen.

Does MMG D:ONE work on a managed or enterprise network?

Yes. You can point it at an NDI® Discovery Server, join specific receive groups, and filter the source list so a given screen only ever sees the sources it should. It takes a static IP or DHCP on Gigabit Ethernet, and each unit reports its own temperature, load and input voltage so you can monitor the estate.

What happens if the NDI source disappears?

You decide. MMG D:ONE can show a branded holding screen, hold the last frame it received, or go to black. You can upload your own full-screen holding image so the room sees your branding between sessions. Every setting survives a reboot.

How much does MMG D:ONE cost?

Image for illustration only. Final product design is subject to change.

Four ways to play

One box, ready for the job in front of it.

Single Source

Put any NDI® source on your network full-screen, in full quality — or switch to a lean proxy stream to keep the network light.

Quad Multiview

Keep an eye on four sources at once. Pick which one you hear, drag them into the order you want, and promote any quadrant to full screen instantly.

USB Media

Plug in a drive and play video and stills straight from it. Build playlists with loop, shuffle and per-image timing, then pause, resume and seek.

Audio Visualiser

Turn the screen into a live visual. A real-time spectrum analyser, or a flowing ambience mode that moves with the beat of whatever is playing.

MMG D:ONE interface — choosing an NDI source

Sources

Everything on your network, one tap away.

MMG D:ONE keeps a running list of every NDI® source it can see — cameras, encoders, switchers, other MMG gear — and appears in that list for everyone else too.

Switch between a single full-screen feed, a quad multiview, or the media player from the same place. Choose full quality when it matters, or a lean proxy when the network is busy — and see exactly what's live, at what resolution, as you do it.

Features

Small box. Serious flexibility.

Hardware HEVC Decode

NDI®|HX runs on the dedicated video block and goes straight to the display on a zero-copy path — 4K at 60fps, with a core to spare.

Audio That Behaves

Master volume on tap, and a buffer that quietly tunes itself to the network — so sound stays smooth and in step with the picture.

USB Media & Playlists

Drives are picked up the moment you plug them in and mounted read-only, so you can swap one over and walk away with it. Mix stills and video, loop, shuffle, and set the timing per image.

Built for Managed Networks

Point it at an NDI® Discovery Server, join receive groups, and filter the source list down to just what that screen should ever see.

Automation Ready

A full REST API and mDNS discovery, so a show controller can drive it. An optional PIN lock keeps the interface in the right hands.

Set It and Forget It

Every setting survives a reboot. A factory reset — from the interface, the API, or the button on the box — puts a unit on a new network in seconds.

Display

The output takes care of itself.

Leave it on Auto and the HDMI output re-tunes itself to match whatever source arrives. Pick a mode by hand and it only sticks once you've confirmed the picture — so you always end up looking at something.

Decide what fills the screen when a source drops: a holding card, the last frame, or black. Upload your own full-screen image and the room sees your branding between sessions.

Then there's Spectrum and Ambience — a live analyser and a flowing visual that moves with the beat of whatever is playing. Trim overscan to the millimetre while you're there.

Set Up in Seconds

Power on. Scan. You're in.

Straight out of the box, MMG D:ONE raises its own WiFi hotspot and paints a scan-to-join QR code onto the display. Scan it with your phone, connect, and you land right in the interface.

The code clears itself the moment you pick something to play. Every setting survives a reboot, and a factory reset — from the interface, the API, or the button on the box — will move a device onto a new network in seconds.

One Screen, Every Unit

Drive one box, or the whole estate.

Point a browser at any MMG D:ONE and you get a live interface that updates itself as things happen — sources appearing, drives being plugged in, displays waking up.

Units discover each other on the network, so any one of them can drive the rest. Control travels over an encrypted mutual-TLS channel, and a device only joins once you approve the six-digit code shown on its own screen.

Each unit reports its own temperature, load and input voltage, so you can see every screen in the building is running happy — long before the doors open.

Use Cases
