Introduction

This guide describes how to transport NDI® content over the public internet with very low latency using high quality compression to reduce transport bandwidth requirements. NDI from NewTek lets you transmit and receive broadcast-quality video with very low latency over Gigabit Ethernet networks. With Zixi, NDI can be ingested on the LAN at one location and then compressed to high quality AVC/H.264 or HEVC/H.265 to be delivered to another location over the public internet to any distance, using the reliable, low latency Zixi protocol. Then at the receiving location the stream can be decoded and broadcasted on the local LAN as NDI. While a single 1920×1080@30 fps NDI stream may require 125 Mbps of bandwidth on the local network, once it is compressed for delivery with Zixi it will only require 10 to 15Mbps using HEVC/H.265 and no perceptible quality loss, to move the stream over the public internet.

About This Guide

This guide demonstrates a basic use case for using Zixi to transport an NDI file over the internet. In this example, an NDI stream is ingested by the Zixi Broadcaster where it is compressed and delivered to another Zixi Broadcaster where the stream is decoded and then broadcasted with no perceptible quality loss.
