NMOS Software Core
Nextera’s NMOS Software Core enables SMPTE ST 2110 based products to interoperate on a multi-vendor IP network and brings plug and play and push-button simplicity to AV over IP routing. Developed by the Advanced Media Workflow Association (AMWA) and specified by the Joint Taskforce on Networked Media (JT-NM), the goal of NMOS is to provide a means for straightforward interoperability between products from a wide range of manufacturers, enabling end users and service providers to build systems using best-of-breed components from multiple manufacturers.
Recognized for their crucial contribution to interoperability, the NMOS specifications are mandated by the European Broadcasters Union (EBU) as part of their “Minimum User Requirements to build and manage an IP-based Media Facility.” NMOS is also mandated by the Joint Taskforce on Networked Media in JT-NM Technical Recommendation TR-1001-1:2018
*A full reference/demo design project is provided along with all of the drivers, daemons, system control software, and a Web GUI so customers can start with a working system and customize to their needs.

IS-04 and IS-05 System Diagram
IS-07, Event & Tally
IS-07 provides the IP equivalent of GPIO events. It provides a mechanism for carrying time-sensitive information over IP, such as camera tally information, control panel button presses and status, and audio levels. IS-07 sends lightweight messages using WebSocket or MQTT, and message flows are connected using IS-05.
IS-08, Audio Channel Mapping
IS-08 introduces Audio Channel Mapping, a key feature enabling audio channels to be re-mapped at the transmitter or receiver. The IS-08 API interacts seamlessly with the IS-04 Registry and IS-05 Connection Management API, allowing the routing of multiple diverse audio streams to any receiver.
IS-08 Audio Channel Mapping is crucial for all ST2110 IP video applications where audio streams need to be combined independently of their associated video streams, a common requirement for broadcast and production studios. This capability was present in SDI-based routing systems, and IS-08 enables the same capability in IP.
IS-09, System Parameters
IS-09 allows an NMOS Node to obtain global configuration parameters used across the entire SMPTE ST 2110 system. The global configuration parameters are stored in a DNS server on the system, discoverable on powerup by DNS-SD. IS-09 enables the media node to start or re-start in a way that is consistent with the environment it is running in.
IS-11, Stream Compatibility Management
IS-11 reports supported AV formats to controller to ensure compatibility. IS-11 allows the configuration of media parameters of Senders and Inputs using information coming from Receivers and Outputs.
IS-13, Annotation and Labelling
IS-13 facilitates easy identification of nodes and devices. IS-13 allows control and monitoring applications to update resource labels, descriptions and tags.
BCP-003-01, Secure NMOS
Encrypts NMOS communications using HTTPS and TLS ensuring only authenticated users have access.
