NMOS is an open set of specifications enabling discovery, connection management, control, and interoperability of media devices and functions across professional IP infrastructures such as SMPTE ST 2110 networks.
NMOS—Networked Media Open Specifications—is a family of open, royalty-free specifications developed by the AMWA (Advanced Media Workflow Association) to enable interoperability and standardized control in professional media-over-IP environments.
Key NMOS specifications include IS-04 (Discovery & Registration), which enables devices and media resources to be automatically discovered and registered, and IS-05 (Device Connection Management), which provides a standardized, transport-independent mechanism for establishing and managing connections between media senders and receivers. IS-08 (Audio Channel Mapping) extends this approach by providing standardized control over the mapping of individual audio channels within compatible devices and media functions.
Together, these specifications reduce the need for proprietary integrations and manual configuration, making it easier to build scalable, multi-vendor IP media networks.
What Nevion Does
Nevion supports NMOS across both its VideoIPath media orchestration platform and Virtuoso software-defined media node and media functions, enabling standards-based integration and control in multi-vendor IP environments:
- VideoIPath includes NMOS Registry and Discovery functionality, enabling NMOS-compliant devices and resources to be discovered and registered using IS-04. It also uses IS-05 for standardized connection management between media senders and receivers. This enables VideoIPath to orchestrate NMOS-based equipment alongside devices controlled through other protocols and device-specific integrations.
- Since 2019, VideoIPath has supported operation as an IS-04 Registry, discovering and cataloguing NMOS resources and using IS-05 to orchestrate media connections. This allows NMOS and non-NMOS devices to be incorporated within the same centrally orchestrated media network.
- Virtuoso media functions support NMOS as part of their integration into IP-based media workflows. IS-04 enables supported Virtuoso resources to be discovered and registered within an NMOS environment, while IS-05 enables standardized connection management of media senders and receivers. Where channel-level audio routing and mapping are applicable, IS-08 provides standardized Audio Channel Mapping capabilities.
By supporting NMOS in both VideoIPath orchestration and Virtuoso media processing, Nevion enables customers to combine centralized SDN control with open, standards-based device and media-function interoperability across SMPTE ST 2110 and other professional media-over-IP environments.
