What Is NDI? A Complete Guide to Network Device Interface for AV & Video Streaming

What is NDI (Network Device Interface) and How Does It Work?

NDI, or Network Device Interface, is a revolutionary IP video standard developed by NewTek that allows video-compatible devices to send and receive high-quality video over a standard local area network (LAN). This enables seamless communication between multiple video systems using existing infrastructure, significantly reducing the need for expensive, point-to-point cabling like HDMI or SDI.

NDI compresses and transmits video over IP with remarkably low latency, allowing users to switch, record, and stream video with incredible efficiency. With support across a wide range of software platforms and hardware devices, NDI is becoming a staple in AV communication and content production.

Why NDI Is a Game-Changer for AV Over IP Workflows

NDI has transformed the AV industry by replacing traditional video cables with flexible network-based workflows. This shift allows for the use of standard Ethernet cables and network switches to manage multiple video sources and destinations across a facility.

For AV professionals, this means easier setup, lower costs, and greater scalability. NDI also supports metadata, tally information, and bi-directional communication, making it an ideal choice for live video production, streaming, and remote collaboration.

How NDI is Used in Real AV Setups

From live event broadcasting and church services to corporate meetings and educational content, NDI is used in a wide range of real-world applications:

• Corporate AV: Streamline meeting room and presentation setups with fewer cables and seamless camera switching.

• Education: Enhance virtual and hybrid learning environments with smart camera switching and screen sharing.

• Live Events: Broadcast concerts, conferences, and sports with lower latency and more camera angles.

• Houses of Worship: Share services online with smooth switching between multiple cameras.

• Content Creation & Gaming: Simplify streaming setups and produce multi-source video content efficiently.
