NDI
What is NDI?
NDI (Network Device Interface) is a high-quality, low-latency video standard developed by NewTek that enables video to be delivered over IP networks. It revolutionizes video production by allowing multiple video sources to be shared across a network with minimal delay.
Key Features of NDI Technology
- Low-latency video transmission (typically under 100ms)
- High-quality 4K video support
- Bi-directional communication over IP networks
- Compatibility with major video software and hardware
- Minimal bandwidth requirements compared to traditional methods

NDI FAQ Section
NDI Technology Questions
Q: What are the main benefits of using NDI over traditional video connections?
A: NDI offers several advantages including reduced cabling requirements, greater flexibility in system design, lower infrastructure costs, and the ability to easily scale your video production setup. Unlike traditional connections that require point-to-point wiring, NDI allows any device on the network to access any video source, making it ideal for modern production environments.
Q: Can NDI be used for live broadcasts?
A: Absolutely. NDI was specifically designed for live production environments. Its low-latency characteristics (typically under 100ms) make it perfectly suitable for live broadcasts, switchers, and production workflows. Many professional broadcast facilities have successfully implemented NDI for their live productions.
NDI Setup Questions
Q: What kind of network infrastructure do I need for NDI?
A: For optimal NDI performance, you'll need a gigabit network (1Gbps) for HD content and a 10Gbps network for 4K streams. The network should be properly managed with quality switches that support multicast traffic. While NDI can work on shared networks, we recommend dedicated networks for professional production environments to ensure consistent performance.
