Networked Media Open Specifications (NMOS) are a group of open-source specifications intended to allow interoperability on the control layer for media devices on an Internet Protocol (IP) infrastructure.[1] NMOS provide discovery, registration and control services for the SMPTE ST 2110 media over IP networks, and other media over IP applications.[2]
The NMOS specifications were created by the Advanced Media Workflow Association (AMWA), and are made available under the Apache-2.0 Licence.
The first NMOS specification (IS-04 v1.0.0) was published by AMWA in April 2016.[3] There have been 15 total published releases of the IS-04 NMOS Discovery and Registration Specification, the most recent being v1.3.3 in December 2024.[4][5]
The NMOS Connection Management API (IS-05) was released in October 2017. There have been 6 total published releases of IS-05, the most recent being v1.2.2 in October 2022.[6]
There are currently two NMOS interface specifications (IS) deemed critical for the success of ST 2110:[2][7]
There are six other NMOS specifications:[8]
The development of at least two more specifications (IS-13 and IS-14) is in progress. IS-06 - Network Control is deprecated as of September 2022.[9]
NMOS specifications have been endorsed by several industry organizations, including the European Broadcasting Union, which published a position statement in 2019 urging the accelerated adoption of NMOS.[10] The Joint Task Force on Networked Media (JT-NM) have endorsed NMOS as a key enabling technology for SMPTE ST 2110 environments.[11] Leaders from technology companies like Sony and Nextera Video have spoken on record about their support of NMOS.[12]
