What is NMOS? A semiconductor technology? Yes, but in the context of broadcast, it is something very different - a set of specifications that enable practical deployments of video over IP. Why is it important? If you plan to transition to IP, even partially, the information in this paper will demystify the control plane and enable you to appreciate how to orchestrate a media over IP network.
SMPTE ST 2110 has emerged as a key technology enabling flexible and scalable Video over IP infrastructures to be deployed. Until recently, there was an absence of a common control system. Spearheaded by the Advanced Media Workflow Association (AMWA), the Networked Media Open Specification (NMOS) previously defined IS-04 (Registration & Discovery) and IS-05 (Connection Management), which was a great start to getting a standardized control system in place and met the needs of many users.
In order to meet the needs of all users, additional functionality was added to address some of the growing pains associated with transitioning to switched packet media transport. With the goal of going beyond the capabilities and security provided in SDI systems, the NMOS specifications dramatically improve the user experience.
The latest advancements in NMOS, including IS-07 (Event & Tally), IS-08 (Audio Mapping), IS-09 (System Discovery), and some Best Current Practices (BCPs) take NMOS to a new level, surpassing the level of control provided in SDI while also adding a layer of security that has been sorely needed in control systems for quite some time.
NMOS also addresses the needs of the system integrator and studio builder, enabling automatic discovery of important services required to configure endpoints automatically on startup.
This paper will dive into the details about what NMOS is, how it works, and then look at a case study of how NMOS was extended to handle a new application – secure control rooms.
