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]
History
[edit]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]
Interface specifications
[edit]NMOS Interface Specifications (IS) specify HTTP APIs to support interoperability between systems. There are currently two Interface Specifications deemed critical for the success of ST 2110:[2][7]
- IS-04 - Discovery and Registration – IS-04 helps devices find each other and announce their capabilities.
- IS-05 - Connection Management – IS-05 allows the configuration of connections between devices called Senders and Receivers.
There are several other published NMOS Interface Specifications:[8]
- IS-07 - Event and Tally
- IS-08 - Audio Channel Mapping
- IS-09 - Systems Parameters
- IS-10 - Authorization
- IS-11 - Stream Compatibility Management
- IS-12 - Control Protocol
- IS-14 - Device Configuration
(IS-06 - Network Control - is deprecated as of September 2022.)[9]
Other specifications
[edit]As well as Interface Specifications, AMWA publishes Data Specifications, Best Current Practice and Informative Documents to support NMOS.
Work in Progress
[edit]The AMWA develops NMOS Specifications in Working Groups that are authorized by the AMWA Board. The Working Groups operate within a specific scope. Work product under development is called Work in Progress. Work in Progress is publicly visible very early in the process.
Recognition & reception
[edit]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]
