Draft:Networked Media Open Specifications

Networked Media Open Specifications (NMOS) are control-plane APIs for interoperability and management of IP-connected audio and video devices. The first, and best known, specifications are IS-04, for discovery of devices, and IS-05, for connection management of devices, and are supported by many devices using SMPTE 2110 digital video networking. More recent specifications cover areas including security, audio channel mapping, device control and support for compressed streams. While a number of proprietary control systems exist in the broadcast media marketplace, there is an increasing demand on the part of end users for an open, collaboratively developed, interoperable control plane in the industry.

The NMOS specifications have been created by the Advanced Media Workflow Association, and are made available under the Apache-2.0 Licence. Several NMOS specifications are recommended by the Joint Task Force on Networked Media, a group of broadcast media industry bodies. NMOS is mandated by the European Broadcasting Union (EBU) as part of their "Minimum User Requirements to Build and Manage an IP-based Media Facility Using Open Standards & Specifications".

Many media devices that support SMPTE ST 2110 digital video support at least IS-04 and IS-05. Open source implementations and test tools are available for developers.
