NDI™ (Network Device Interface) is an open protocol developed by NewTek™ to enable video compatible products to share video across a local area network. We believe that the future of the video industry is one in which video is transferred easily and efficiently in IP space, and that this vision will largely supplant current industry-specific connection formats (HDMI, SDI, etc.) in the production pipeline.
NDI allows multiple video systems to identify and communicate with one another over IP, and to encode, transmit and receive many streams of high quality, low latency, frame-accurate video and audio in realtime. This new protocol can benefit any network-connected video device, including video mixers, graphics systems, capture cards, and many other production devices.
NDI can operate bi-directionally over a local area network, with many video streams on a shared connection. Its encoding algorithm is resolution and frame-rate independent, supporting 4K (and beyond) along with 16 channels (and more) of floating-point audio. The protocol also includes tools that implement video access rights, grouping, bi-directional metadata and IP commands. And its superb
performance over standard GigE networks makes it possible to transition facilities to an incredibly versatile IP video production pipeline without negating existing investments in SDI cameras and infrastructure, or costly new high-speed network infrastructures.
