NMOS - Networked Media Open Specifications

Fundamentals

​

An Introduction to the AMWA Networked Media Incubator project  4:47

Brad Gilmer, AMWA

 

1. Introduction to Networked Media Open Specifications  9:08

Andrew Bonney and Alex Rawcliffe, BBC R&D

An introduction to the current specifications in progress, their data model and key concepts.

 

2. NMOS: Discovery and Registration  8:39

Andrew Bonney and Alex Rawcliffe, BBC R&D

A robust and scalable approach to Discovery is essential element of real-world management networked media.  This presentation describes how to use NMOS's Node, Registration and Query APIs for discovery, from small peer-to-peer cases to large installations.

 

3. NMOS: Connection Mangement  2:52

Andrew Bonney and Alex Rawcliffe, BBC R&D

NMOS allows Senders and Receivers to be connected in a transport-agnostic way.  Andrew and Alex describe how to do this using the Node API.

 

4. NMOS: In-stream Identity and Timing  4:18

Andrew Bonney and Alex Rawcliffe, BBC R&D

NMOS provides a universal identity model for content and an end-to-end timing model, both important elements of a future-proof networked media architecture.  This presentation explains these contents, and how they are mapped to media streams.

 

Demonstration of NMOS Registration and Discovery  3:40

Alex Rawcliffe, BBC R&D

An example of NMOS Registration and Discovery in action using software and hardware from multiple manufacturers.

​

NMOS Now and Next  28:43
Peter Brightwell, BBC R&D

An introduction to the AMWA Networked Media Open Specifications, including an outline of the specifications themselves, how they have been developed and tested, the state of industry adoption, and broadcaster perspectives.

​

AMWA NMOS Automated Testing  30:41
Andrew Bonney, BBC R&D and Gareth Sylvester-Bradley, Sony Europe

An introduction to the open source AMWA NMOS Testing Tool, which can be used to automatically ensure that Media Nodes and other appliances are adhering to the NMOS specifications.

​

NMOS IS-07 – GPI Replacement and Much, Much More  23:58

Miroslav Jeras, Pebble Beach Systems

IS-07 Event & Tally is part of the NMOS suite that defines how states and state changes are communicated in an IP environment.  It is not only a GPI replacement but it also provides a platform for resolving many other problems broadcasters are facing in the IP transition.

​

Security for Discovery and Connection management of ST 2110 Media Devices  25:30

Arne Bönninghoff, Riedel Communications

This session describes the current workflow of the BCP-003 Security best practices, including proposed mechanisms to encrypt NMOS APIs with TLS to prevent man in the middle attacks.  Furthermore, AMWA IS-10 is reserved to specify authorization mechanisms to secure access to NMOS APIs like IS-04, -05, or -08.

​

Using AMWA IS-06 for Flow Control on Professional Media Networks  26:15

Rob Porter, Sony Europe and Sachin Vishwarupe, Cisco Systems

AMWA IS-06 is an open specification for setting up and modifying flows on a professional media network, allowing the use of Software Defined Networking to both authorise and optimise network usage. This presentation describes the current IS-06 APIs and some of the future areas of development.

AMWA NMOS: The Whole Story  31:25

Brad Gilmer, AMWA and Peter Brightwell, BBC R&D

This talk serves as an introduction to AMWA NMOS, covering all parts of this suite of interface specifications and best practices.  It also touches on why we’re creating it, the approach we’re taking, and how it’s being implemented.  The AMWA IS-04 and IS-05 interfaces are now recognized as being essential to the industry’s move to interoperable live IP infrastructure. They allow control applications to automatically discover and connect networked media devices and are now mature specifications featured in many products.

​

AMWA NMOS IS 04 and IS 05: Things You Might Not Know  29:31

Andrew Bonney

Did you know for example, that there is no requirement for every node in a system to run the same IS-04 version? This presentation will take a look at some of the lesser-known and more advanced features of IS-04 and IS-05, along with how they may assist you in deploying anything from a small ad-hoc setup through to a large-scale multi-format facility.

​

AMWA BCP 003 NMOS API Security  17:03

Simon Rankine, BBC R&D

BBC Research and Development’s Simon Rankine presents an update from AMWA’s NMOS API Interoperable Security Group which is working to apply tried and tested web technologies to the APIs in order to provide APIs that are simultaneously secure and cross-vendor interoperable.

Scalability and Performance of the AMWA NMOS IS-04 and IS-05 Specifications  27:53

Rob Porter and Gareth Sylvester-Bradley, Sony Europe

A key requirement is that APIs such as those used for AMWA IS-04 and IS-05 scale successfully in the very large installations, typical of real world deployments.  To help address this, Sony has been leading an AMWA NMOS Scalability study to test these protocols for installations comprising thousands of media devices.

Exploring the Role of NMOS: Discovery and Connection in an IP World  1:32:52

Peter Brightwell

SMPTE ST 2110 specifies how to stream video, audio, and data between devices for professional applications using IP networks. How best to discover, connect, and monitor those devices? That is addressed by the Advanced Media Workflow Association (AMWA) Networked Media Open Specifications (NMOS).  This SMPTE Technology Webcast will focus on how different parts of the AMWA NMOS work, in theory as well as in practice, and on how NMOS can be used in a range of applications, whether within a broadcast control room or a cloud-based workflow.
