About NDI

NDI is more than simply video over IP. NewTek NDI (Network Device Interface) offers the ability to share high-quality video over your local Ethernet network. Using NDI, each video source is instantly available to multiple devices and viewers. You can establish this wherever your network extends (broadcast studio, office, campus, etc.). It allows for immediate display, capture, replay, production, and much more.

NDI operates over a local area network (LAN) and support ulta-low latency and ultra-high quality video stream alike, on shared connections. The manufacturer calls it resolution and framerate independent. It natively supports tally, metadata, access management, plus a host of other functions.

NDI enables multiple applications to access the same sources at the same time. An example might be how you can simultaneously send high-quality, low latency video to your video mixer system, while also streaming it and capturing it elsewhere on the network.
