​How Does NMOS Help?



Since the NMOS developments began, there has been a steady demand from users to provide valuable new functionality.  The table below shows the key developments.  These include all that are finished and in use, plus some “work in progress” and future additions.  The successful adoption of NMOS developments in real world systems provides a solid basis for additional work, as both media companies and Pro AV users, working closely with their suppliers, gain benefits from IP-based infrastructures.

Please note - there is a range of material to support these technical developments.  These include Best Current Practice documents, Implementation Guides and Data Model Specifications, which can be found on the Specification page of

​Will it help my business?

NMOS is a fundamental part of an ip-based infrastructure

For an excellent picture of how both vendors and their customers are embracing NMOS and IP-based architectures, the AIMS IP Showcase presentations from IBC2019 shows how NMOS is being developed and adopted in a wide range of applications.

And for end users who want to specify NMOS in their procurement processes, there is a standard form of words, prepared by the EBU.

Is there a risk in adopting it?

SO what for the future?


IP-based infrastructures take us on important first steps, liberating workflows from traditional, hard-wired, point-to-point installations.  However, the professional media industry can also harness the power of IT infrastructures that we have come to expect every day in our office systems.

The future vision​

  • NMOS provides a path to true IT infrastructures.

  • A presentation by Brad Gilmer explains the business benefits that an IT infrastructure can deliver and how flexible professional media workflows can be built using IT principles.

  • At IBC2019, Gordon Castle of Discovery / Eurosport gave his vision for an IT future.
