​How Does NMOS Help?



Since the NMOS developments began, there has been a steady demand from users to provide additional functionality.


Version 2 of the NMOS Roadmap shows all of these key developments, now grouped to show the overall benefits and how they work together.  These include the many developments that are finished and deployed, along with “work in progress” and future additions.


Much of the new work is to accommodate compressed video formats to extend the use of NMOS between media premises and to / from the Cloud.


Also, as the IPMX standard is adopted in the Pro AV market, NMOS will bring valuable plug and play benefits to both end users and suppliers alike.


The roadmap includes Interface Specifications (IS-xx), Best Current Practices (BCP-xx) and Data Model Specifications (MS-xx), to show the functionality and benefits that they offer.


Please note - there is a range of supporting material for these technical developments.  These can be found as INFO documents on the Specifications page of

What you will find 

  • Core Functionality

  • Security Features

  • Compressed Streams

  • Control and Monitoring

  • System Features

  • Testing Tools

Join the family of NMOS users and suppliers


AMWA members have invested thousands of hours in developing the open specifications that are in use today.  But we also encourage non-members to benefit from this development time by including the code, free of charge, in their product range.

See below for a range of resources that are available to help you.

​How can I use it?

NMOS is available form a broad range of vendors


Suppliers worldwide have signed up to participate in the NMOS developments.

Big industry names and small independent specialists are contributing to the working groups, showing a long-term commitment to the success of this initiative.

The JT-NM Tested program offers confidence to purchasers that products have been thoroughly checked by industry experts.

Where can I buy it?

nmos developments are based on real business needs


End users and their suppliers are working towards open standards and specifications to escape the limitations of closed technology solutions.  Customers want the ability to build systems using products with the best features.  Vendors value the ability to make sales into the widest customer markets.

​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.
