Bandwidth

NDI operates most efficiently in a dedicated network with high bandwidth and high availability. This contrasts with unmanaged environments such as the public Internet or networks where video rides along with data without priority.

Gigabit (1000 ) networks are essential in production workflows. A typical NDI stream consisting of 1080 60P video yields a data rate up to 150 Mbps per stream. This extremely efficient stream is designed to have very low latency and allows multiple streams to be stacked together on a single Gigabit network. Even so, a production environment may require more capacity based on a simultaneous number of NDI streams required.

The following tables are intended to calculate bandwidth needs based on video resolutions and frame rates. It should be noted, however, that NDI is not deterministic. The bandwidth needed for NDI should be based on the determination of the .

NDI HX1 is a legacy format that will eventually be discontinued. As such, there are not reference tables for it. Contact our technical support team if you have any questions.
