NMOS is an open set of specifications enabling discovery, control, and interoperability of media devices over IP infrastructures like SMPTE ST 2110 networks.
NMOS—Networked Media Open Specifications—is a family of open, royalty-free API standards developed by AMWA (Advanced Media Workflow Association) to facilitate interoperability and control in professional media-over-IP environments. At the heart of NMOS are IS‑04 (Discovery & Registration), which automates device discovery and resource registration via HTTP/REST and optional DNS‑SD, and IS‑05 (Connection Management), which provides a standard, transport-agnostic way to connect media senders to receivers—supporting staged workflows, SDP transport metadata, and versioned activation. Together, these specs eliminate manual device configuration and Wi-Fi coding, promoting scalable, multi-vendor IP media networks.
What Nevion Does
Nevion integrates NMOS into its orchestration and control toolkit to power flexible, multi-vendor media networks:
- VideoIPath, Nevion’s SDN-based orchestration platform, includes a built-in NMOS RDS (Registry & Discovery Server) to onboard and register NMOS‑compliant devices via IS‑04, while also controlling media path connections using IS‑05—either in combination with device-specific drivers or standalone.
- Since 2019, VideoIPath supports acting as an IS‑04 registry to detect and catalog devices, and using IS‑05 to orchestrate actual media connections between senders and receivers—even bridging NMOS and non-NMOS environments seamlessly Nevion.
Earlier iterations of Nevion’s orchestration software, such as Maestro, also supported NMOS standards, demonstrating Nevion’s long-term commitment to open interoperability.
