Networked Media Open Specifications: Introduction
About NMOS
NMOS is a family name for specifications produced by the Advanced Media Workflow Association related to networked media for professional applications.
For a non-technical introduction to NMOS see AMWA’s overview page and NMOS Roadmap.
The tables below list the current specifications and provide links to their documentation on specs.amwa.tv. The “Release” links will take you to the documentation and download page (↓) for the latest release of recent versions of the specification.
The tables no longer include direct links to the GitHub repos. These are available through the NMOS CI Dashboard.
The NMOS API Testing Tool supports the majority of these specifications.
