Metadata

NDI includes the ability to send XML-formatted metadata messages between NDI senders and receivers using several different methods. This powerful mechanism can communicate status, provide remote control, and serve many other purposes. In particular, the ability to send messages bidirectionally between NDI senders and receivers allows NDI to simplify workflows that would be significantly more complex if implemented with other audio/video streaming protocols.

The following documentation explains how to utilize the metadata capabilities of NDI and includes all standard metadata elements developed to date. As new use cases emerge, expect this list of standards to expand.

We recommend that you use an XML Linter of your choice to prevent any potential syntax errors.
