Getting started with NMOS. AMWA's Networked Media Open Specifications (NMOS) exist to support the industry adoption of an open, inter-operable approach to IP-based infrastructures. NMOS – Getting Started Resources for NMOS Implementers and Integrators There is a continued interest in building systems which use the NMOS specifications and implementing these developments. To make it easy, this page lists the important information that we currently have and where to find it. It’s organised by functional areas (which match those presented on the NMOS Roadmap ): quick links Find out about IPMX and NMOS Info for Purchasers and decision-makers Info for strategic technical people and details on business efficiencies Info for those responsible for making everything work together, integrators, end users Ready to join? ● Core ● Security ● Compressed Streams ● Control & Monitoring ● Systems ● Testing The NMOS Overview page provides links to introductory information about NMOS. The Networked Media Systems - The Big Picture article is an excellent place to start for those looking to get an initial view of how networked media systems work and where NMOS plays a part. Here's a more technical introduction . Getting started quickly There are a few resources that can get you up and running with NMOS relatively quickly. Two things you might want to explore are the Easy NMOS tool from Nvidia and the nmoscpp implementation from Sony. If you already have an initial NMOS implementation, be sure to look at the NMOS Test Utilities and watch a video on the NMOS Test Utilities as well. Asking questions AMWA members can post questions or comments on the appropriate Slack or Basecamp workspaces. Please contact Tina Lipscomb if you do not already have access. Members and non-members are invited to post Issues and questions that have to do with the NMOS specifications, open source implementations or the Testing Tool on the relevant GitHub repo. Non-members are welcome to post technical questions about NMOS on the public AMWA Slack workspace . If you have questions about the AMWA, NMOS-related activities and presentations at upcoming events, etc., please use the Contact Form on the AMWA website. You may also find answers to your questions on the #nmos channel on the video-dev Slack workspace . Specifications The NMOS Roadmap provides a useful summary of the most important specifications, grouped by functional area, with a coloured indication of their status, and target completion date if appropriate. A complete index of published, WIP and deprecated NMOS specifications . The index is grouped by specification type (Interface Specifications, Data Model Specifications, etc) and sorted by specification id (IS-04, IS-05, etc), rather than grouped by functional area. The Technical Overview also explains how to find and navigate through the specifications. All NMOS specifications have their “source” on GitHub, for example https://github.com/AMWA-TV/is-04 , which is automatically formatted and rendered to AMWA’s specification site, e.g. https://specs.amwa.tv/is-04 , including documentation, APIs and examples, and access to particular versions of the specification (for example https://specs.amwa.tv/is-04/latest is the most recent IS-04 release, while https://specs.amwa.tv/is-04/v1.2 is the latest release of IS-04 v1.2) and work-in-progress versions. Informative Documents AMWA Specifications with “INFO-” identifiers are “Informative Documents”, and are used to provide implementation guides and other non-normative information. While informative in nature, and not formal technical specifications, they provide much information on how to use NMOS and are good resources for someone just getting introduced to this ecosystem. For example, the article on NMOS use of DNS-SD provides helpful guidance for those looking to implement DNS-SD in a networked media environment. As with all Specifications, INFO documents. Parameter Registers and Control Feature sets Specifications often make use of defined parameter values in NMOS APIs, for example JSON representing a video Flow will include a format parameter with value urn:x- nmos:format:video. You can find the NMOS parameter registers here . Similarly the NMOS Control & Monitoring specifications make use of “control feature sets” Implementations The “NMOS-controlled products ” page provides links to lists of commercial NMOS-capable media nodes, registries and controllers. There is also a list of open source and free implementations. There have been a number of excellent presentations on NMOS over the years made at the IP Showcase. You can find these on the IP Showcase website under “Resources.” ● AMWA NMOS: Powered by Open Source ● Bringing Up a NMOS-Capable ST 2110 Media Processing Node in 30 Minutes If you have created an NMOS implementation, you will want to look at the section of this document detailing resources available for NMOS Testing.

AAF and its use of COM The Component Object Model (COM) is currently used at the top level API for AAF SDK. it does not imply that the AAF toolkit is particularly tied to Windows or the Microsoft Development Tools, COM in this instance is simply a discipline for writing and maintaining re-usable code libraries. The use of COM shows that the AAF Code and it's libraries and DLL's or shared objects adhere to the principles of Interface Invariance and provided the mechanisms for supporting a robust third party shared code library. On non-Windows platforms COM support is provided by our own portable library - (on Windows the AAF DLL isn't registered with the Registry and you don't use CoCreateInstance to create Objects). Refer to the routines in the ref-impl/src/com-api/com-dll for the specifics of the underlying ImplAAFRoot and AAFUnknown interfaces. It might be interesting to note that the Architecture of the SDK is such that a top level API based on COM is not the only alternative, there is an extra layer of abstraction below the COM API where the meat of the methods is implemented. This implementation layer could equally well act as the foundation for a Java API. The main characteristics of COM-style interfaces are: Invariance of Interface Encapsulation - hiding the implementation Support for QueryInterface dynamic casting (Unique Interface Identifiers) Built-in reference Counting for pointers to Objects The first thing most people have done when building on top of the AAF COM API is to add some kind of Reference counting and smart pointers. See the new AxExamples or the EDL2AAF project. Further reading Essential COM, Don Box, Addison Wesley 1998 Inside COM, Dale Rogerson, Microsoft Press 1997 Helper Functions The example program InfoDumper probably shows the best structure for using the COM API, Generally it helps to have extra Template Classes to simplify the reference counting, where InfoDumper makes use of IAAFSmartPointer James Cain's EDL2AAF introduces his own glue class cUnknownPtr to achieve the same goal. Issues of navigation around interfaces... One school of thought (currently implemented in AAF) is to use QueryInterface exclusively to discover the inheritance hierarchy of a Class. Whilst following the spirit of COM this can lead to a large number of QueryInterface calls while you 'probe in the dark' trying to find what interfaces a particular interface supports. There is a suggestion that for a later version of the SDK that a new interface be introduced that uses public Interface Inheritance as an alternative to the current system where there is no predictable relation between the different interfaces a particular object can have. In the current scheme the only way to find if an object supports an interface to call QueryInterface on it, even if you know from the implementation that an IAAFSourceClip is also an IAAFComponent.

AS-11: Media Contribution File Formats The AMWA AS-11 family of Specifications define constrained media file formats (based on MXF) for the delivery of finished media assets to a broadcaster or publisher. Each Specification is developed for a particular business purpose. The AS-11 Overview GitHub project is used to host additional resources for all the AS-11 Specifications including an issue tracker, sample files, tools, and more information. History of AS-11 development The AS-11 UK DPP HD & SD Specifications are well established for the delivery of finished programs to media companies within the UK. Traditionally, AMWA Specifications have been text-based. While being easily human-readable, they do not support automated processes or allow the Specification to be quickly and efficiently adapted for new users. This has led to the development of Rules-based, machine-readable Specifications. Building blocks (“rules”) for all the video, audio, metadata, etc aspects are combined into the final Specification. Human-readable descriptions can be generated automatically from the machine versions, and these building blocks can be re-used in other Specifications. This new approach has proven especially valuable as the AS-11 family of Specifications has been extended to accommodate the needs of new international users. New specifications have been created to: Meet the requirements of broadcasters in the Nordic countries, Australia and New Zealand, as well as broadcasters represented by the North American Broadcasters Association (NABA) and the DPP Add support for UHD and HDR content Cater for delivery of short-form content in addition to full-length programs (such as commercials, promotions, and music videos)

The information has been provided in the form of Frequently Asked Questions. If you have any further questions, don’t hesitate to Contact Us . Technical information which has been published, is available at https://amwa-tv.github.io/nmos/ What are Networked Media Open Specifications? Who is supporting this initiative? What is the technical basis for the NMOS project? What is the Networked Media Incubator? What are IS-04, IS-05, IS-06, etc? Where can I find technical details of the specifications? How can my company participate? Is there an NMOS compliance / certification process? When will NMOS specifications become standards? What are Networked Media Open Specifications? The Networked Media Open Specifications (NMOS) have been developed for use in IP-based infrastructures to provide a control and management layer in addition to the transport layer provided by SMPTE ST2110. The goal is to provide a means for straightforward interoperability between products from a wide range of manufacturers, in order that end users and service providers can build best-of-breed systems. As in the past, successful sales by a supplier will depend on matching their customer’s needs for functionality. NMOS simply seeks to make the interconnection of products from competing suppliers as simple as possible. The NMOS family of specifications began with projects for Discovery & Registration, Device Connection Management and Network Control. It has grown to include important subjects such as Event & Tally, Audio Channel Mapping and Interoperable Security. Additional working groups become active as new operational / business needs are identified. They are a growing family of specifications which are available to both suppliers and end users, at no cost, to support the development of products and services which work within an open industry framework. Wherever possible, the specifications are being developed using Internet standards or Internet-friendly techniques. Back to the top Who is supporting this initiative? The NMOS initiative is supported by the Joint Task Force on Networked Media (JT-NM), comprised of four organisations; the AMWA, EBU, SMPTE and VSF. http://www.jt-nm.org/ The work of the AMWA complements and, in turn, supports the contributions from the other organisations. More than 70 AMWA members, end users and their suppliers, have signed up as participants in this project and are active in the working groups that most directly affect their business. The list ranges from large, multinational suppliers to single person consultancies. The list of end users and suppliers . The JT-NM works closely with the Alliance for IP Media Solutions (AIMS) to provide education and advocacy across our industry. Back to the top What is the technical basis for the NMOS project? In 2015, the JT-NM published a Reference Architecture which describes a conceptual model for interoperability. It is designed for contribution that will allow end users and manufacturers to truly benefit from the cost saving, flexibility and scalability of an Internet-based approach. However, the Joint Task Force did not go as far as working on specifications or encouraging implementations. Instead, they laid out the Reference Architecture and a collection of best practices, leaving it to initiatives such as NMOS and the AMWA Networked Media Incubator project to work out the details and to get implementers together to create interoperable solutions. Back to the top What is the Networked Media Incubator? This is a key project set up to enable the creation of a family of Open Specifications. The Networked Media Incubator project is sponsored by the AMWA to enable open, multi-vendor interoperability in professional media networks. The activity is focused on getting early tangible results by concentrating on specific technical areas through a series of collaborative development activities and facilitating virtual and physical interchanges between system developers. The technical goals of the group are guided by the JT-NM’s Reference Architecture. The Networked Media Incubator (also simply called the "Incubator”) was set up in September 2015 as an “umbrella” project, under which the working groups could operate. The number of working groups has grown steadily and most hold weekly or fortnightly conference calls in addition to technical discussions on the Basecamp project forum. Regular developer workshops take place throughout the year. These are open to any AMWA member which has software to test. The workshops provide a supportive environment where developers share experiences to the mutual benefit of all participants. To encourage openness and discussion, there is strict rule not to speak negatively about any other participant who takes part in a workshop. Back to the top What are IS-04, IS-05, IS-06, etc? These are Interface Specification (IS) identifiers assigned to the NMOS specs. Specifications are formally given an IS number once they reach Specification status. Other supporting specifications may have different numbering, such as "BCP", for Best Current Practice. Details of all specifications can be found by the link at the top of this page. NMOS APIs are built on widely adopted patterns used on the Internet/Web, using open-source components wherever available. Back to the top Where can I find technical details of the specifications? An overview can be found at https://amwa-tv.github.io/nmos/ with more detailed documentation starting at https://github.com/AMWA-TV/ . NMOS specifications are made publicly available (Apache 2 licence) as early as is practical, and at the latest on elevation to AMWA Specification. Note that some specifications are in private repos in their early stages. These are accessible to AMWA NMOS participants (if you are a member who needs access, please contact the Incubator or activity lead). As well as proprietary implementations, several open-source implementations of IS-04 and IS-05 are available. These are available via the first link above. At the time of writing, they all use the Apache 2.0 license, which matches the NMOS specifications themselves. If you have an implementation you would like added, please create an issue against this repository indicating where it is available from. Back to the top How can my company participate? Any company can join this work by becoming a member of the AMWA and signing the Rules document **. Membership provides access to all current NMOS projects and a shared IPR framework through the AMWA’s IPR policy. There are three company membership levels plus an individual membership. Details of the range of membership benefits are available via the JOIN button at the top of this page. If you have questions of any sort, please use the CONTACT button above. Please note that the NMOS Incubator project is "RAND-Z" so it requires any contributions to be made available on a reasonable and non-discriminatory basis at zero cost. ** The Rules document exists simply to support open, honest communication and ensure that no participant speaks negatively about a competitor following discussions and / or developer workshops. Back to the top Is there an NMOS compliance / certification process? At present, there are interoperability checklists at workshops and in preparation for public demonstrations but these are for use for testing by suppliers and do not let vendors formally claim compliance. The AMWA does not currently provide a certification process for NMOS implementations. Back to the top When will NMOS specifications become standards? Development of an Interface Specification reaches a point where it is sufficiently advanced to be formally elevated to an “AMWA Specification”. However, further versions of NMOS specifications are likely, for example, to support the additional requirements of newer, later specifications. Also, as the professional networked media industry matures we can expect end user requirements to evolve so, although individual versions will become “Stable” and widely implemented, NMOS will not stand still. This need to accommodate evolving end user requirements does not allow as easy fit with the traditional standards processes which have worked so well for transport streams such as SMPTE ST2110.
