Why NDI?

Why NDI?

Traditional AV networks are set up on their own infrastructure, with cables running between AV transmitters, receivers and a matrix system, with the number of sources limited by the ports on the matrix.

With AVoIP systems the basics are similar – transmitters become encoders, receivers become decoders and the matrix is replaced by an IP switch, but that is where the similarities end. AVoIP frees workflows from the limitations of point to point systems and allows content to be distributed in the same way as other IP traffic with both flexibility and scalability. It also allows remote monitoring, control and contribution. Moving away from traditional AV networks opens the door to new ways of working, the world of NDI and its boundless capacity for remote production.

So what is NDI?

NDI (Network Device Interface), is a free protocol developed by NewTek that enables devices and applications to connect and communicate over standard IP networks to share video, audio and data. There has never been a simpler way to connect video equipment together. New devices are automatically discovered and available to all other systems on the network making video production, streaming and conferencing applications simple to deploy, manage and scale.

There are thousands of NDI developers and a wide range of products already available from manufacturers like Adobe, Avid, BirdDog, Microsoft, Newtek, Panasonic and VLC. 

Key Features

Easy to setup/configure

  • Auto discovery
  • Ability to span networks & subnets
  • Find sources by name

Completely interoperable

  • Between NDI® applications
  • Between versions
  • Between standards


  • Works on all networks and even in the cloud delivering frame-accurate, high quality video at the lowest latency.
  • Allows multiple video sources to work simultaneously on 1GbE networks and grows to 10Gbit and beyond for massive scaling up to almost unlimited streams and resolutions.
  • Supports embedded alpha channel for keying, control, tally, metadata, precision time stamps and now, via BirdDog even Dante audio.
  • Extends to mobile integration over WiFi using mobile devices as sources and streaming out to websites and social media platforms, utilising computers, webcams, media players, and media applications as NDI sources and destinations. 
  • NDI is bi-directional, so any source can also be a destination.


NDI HX is a high-efficiency version of NDI.

NDI | HX is much slimmer, so it can be used in much more bandwidth restrictive environments. At 15mb, an NDI | HX camera can be connected through a wide area network, the tradeoff being that there are a few frames (3) of latency with NDI | HX.
