Comment: This article needs to be rewritten to be understandable to a general audience. Currently it is highly esoteric and uses technical language. The references are not formatted correctly; please use the citation generator to generate correct references. Also, please check whether the article is notable according to independent, reliable sources. If it is not or if it is borderline, the topic may be a better fit for adding some mention to an existing article, rather than creating a new standalone article.

Networked Media Open Specifications (NMOS) is the collective name for a group of specifications produced by the Advanced Media Workflow Association[1] (AMWA) related to networked media for professional applications. NMOS provides users with an open and simple to use control-plane solution that enables interoperability and management of IP-connected audio and video devices.[2]
Origins of NMOS
NMOS is designed to help broadcasters and pro AV customers migrate from legacy connectivity (SDI) to IP formats, which are now increasingly prevalent in broadcasting, media production and professional AV.[3] Comprising a growing set of specifications, NMOS provides seamless management of video, audio and data streams for interactive and interoperable production of live content. Open and free of charge, NMOS is available to all stakeholder groups, including end-users, suppliers, integrators and hire companies.[4]
Foundational technologies
Intended to enable a smoother transition from legacy SDI to new IP-baed workflows, NMOS synthesises existing specifications and standards, and expands upon them with additional functionality. NMOS is based on existing work from other well-established technology organisations, including the Society of Motion Picture and Television Engineers (SMPTE), European Broadcasting Union (EBU), Audio Engineering Society (AES) and Video Services Forum (VSF).
Two key technical recommendations from the VFF, TR-03 and TR-04, were important in the creation of ST 2110 and NMOS.[5] Published in October 2015, TR-03 provides for the carriage of video, audio and ancillary data as separate elementary streams that can be individually forwarded through an IP network. TR-04 builds on the capabilities of TR-03 to allow complete SDI signals that have been encapsulated using ST 2022-6 to interoperate more easily with TR-03-based systems via compatible RTP time-stamping and common SDP constructs.
Recognising that there was still a requirement for more clarity around discovery & registration, AMWA built on this work to develop two new technical specifications: AMWA IS-04 Discovery and Registration Specification[6] and AMWA IS-05 Device Connection Management Specification.[7]
Recent developments
Work continues on revisions to existing specifications (although many are now regarded as stable) and the development of new ones. For example, at the start of 2024, NMOS announced four new specifications that, collectively, provide a full control plane solution: NMOS Control Architecture (MS-05-01), NMOS Control Framework (MS-05-02), NMOS Control Protocol (IS-12) and NMOS Control Feature Sets Register.
This part of the NMOS project was explored in detail by IBC 365 (https://www.ibc.org/connective-tech/features/nmos-control-project-what-does-the-latest-development-mean-for-ip-production/21349), the content platform of the International Broadcasting Convention.
Current projects include the development of an open source NMOS Receiver & Sender with fully integrated NMOS Control and Media planes. It is anticipated that both of the related specifications, BCP-008-01 (NMOS Receiver Status) and BCP-008-02 (NMOS Sender Status), will be completed later in 2025.
The full list of NMOS specifications, recommendations and guidance can be found at the NMOS website.[8]
