Video: Securing NMOS Apps

The still-growing NMOS suite of specifications from AMWA defines ways in which your IP network can find and register new devices plugged in to it (e.g. camera, microphone etc.), manage their connections and control them. They fit neatly along side the SMPTE ST 2110 suite of standards which define the way that the essences (video, audio, metadata) are sent over networks intended for professional media.

As such, they are core to a network and as the market for uncompressed media products matures, the attention is on the details such as whether they scale and security.

In this talk, Simon Rankine from BBC R&D starts by explaining the objectives which means looking at the different aspects of security which is split into three; securing data transfer, ensuring data goes to the right place, ensuring only authorised people can act.

TLS, standing for Transport Layer Security, is the same protocol used for secure websites; those which start with https://. It is also referred to by the name of the protocol it replaced, SSL. Given the NMOS APIs are sent over HTTP, TLS is a perfect match for the use case. TLS provides not only the ability to encrypt the connection but also provides the basis for certificate exchange which allows us trust that the data is being sent to the right place. Simon then covers ciphers and TLS versions before talking about certificate management.

This talk was given at the IP Showcase at NAB 2019.

Video: A Basic Guide For Real-Time IP Video

There are a lot of videos looking into the details of uncompressed video over IP, but not many for those still starting out – and let’s face it, there are a lot of people who are only just embarking on this journey. Here, Andy Jones takes us through the real basics do prove very useful as a building block for understanding today’s IP technologies.

Andy Jones is well known by many broadcast engineers in the UK having spent many many years working in The BBC’s Training and Development department and subsequently running training for the IABM. The news that he passed away on Saturday is very saddening and I’m posting this video in recognition of the immense amount he has contributed to the industry through his years of tireless work. You can see from this video from NAB 2018 his passion, energy and ability to make complicated things simple.

In this talk, Andy looks at the different layers that networks operate on, including the physical layer i.e. the cables. This is because the different ways in which traffic gets from A to B in networking are interdependent and need to be considered as such. He looks at an example network which shows all the different standards in use in an IP network and talks about their relevance.

Andy briefly looks at IP addresses and the protocol that makes them work. This underpins much of what happens on most networks before looking at the Real-time Transport Protocol (RTP) which is heavily used for sending audio and video streams.

After looking at how timing is done in IP (as opposed to black and burst) he has laid enough foundations to look at SMPTE ST 2110 – the suite of standards which show how different media (essences) are sent in networks delivering uncompressed streams. AES67 for the audio is also looked at before how to control the whole kit and caboodle.

A great primer for those starting out, watch now!

Video: AMWA NMOS State of Play

With all the talk of the SMPTE ST 2110 standards suite, it’s sometimes forgotten that it only deals with content. If you want a working system, you’ll need to do a few more things – find new devices on the network, work out what they can do, control them, guarantee the bandwidth and often deal with metadata that arrives separately like tallies.

This is what the AMWA NMOS specifications do. Peter Brightwell and Thomas Edwards have been heavily involved in creating them and in this video lead us through what each one does and how they are used.

Video: Designing and Utilising SMPTE 2110 for Broadcast: Opportunities and Challenges

A meeting of experienced minds here at the Pittsburgh SMPTE section talking about the opportunities and challenges of ST-2110. Phil Myers from Lawo talks optimistically about the challenges that can and often have been solved in implementing 2110 whether that be network infrastructure or timing, giving a good primer on the whole topic as he starts the session.

Hugo Gaggioni from Sony, talks about NMOS, explaining what AMWA does and the difference between their IS-04,05 and 06 specifications.

Karl Kuhn from Tektronix then discusses packet pacing, PTP and network architectures. He then looks at how to monitor PTP and see it is working well.

With the panel session at the end, joined by Dan Turk from NEP, there is a free-ranging discussion covering some of the following topics:

  • Control of IP networks
  • The limits of IP
  • Multicast traffic
  • Network Architecture
  • True non-blocking switches
  • Break-even points of IP systems
  • Split essences & dropping blanking
  • Network planning for UHD
  • Handling loss of network on PTP implementations
    plus much more!

Webinar: Control and Monitoring in an IP Infrastructure

Date: Monday 19th November 2018, 08:00 GMT and again at 16:00 GMT

Axon’s back with their 5th webinar in the Broadcast IP 101 series. Previously they have covered preparing for IP, the basics, Transport Formats and uncompressed vs compressed video. Now they are back to talk about control and monitoring.

The well-known 2022 and 2110 standards define transportation of video (and other essences). Like SDI-related standards, they don’t describe how to control the path of signals or monitor them. Unlike SDI, however, we expect to know what’s plugged in to our networks (AKA discovery) and then to control the data flow. There are proprietary and open specifications for doing this, including AMWA IS-04, IS-05 and IS-06 which deal with discovery, control and connection management.

In this webinar, CTO Peter Schut describes the lay of the land and how you can implement control and monitoring in an IP infrastructure.

The webinar happens twice. Once at 08:00 GMT (Midnight PT) and once at 16:00 GMT (11am ET).

Meeting: Further adventures in the world of IP: SMPTE2110 and NMOS


Learn what the SMPTE 2110 standards are and how they affect the future of professional media over IP networks with our speakers David Atkins and Ed Calverley. Now at a bigger venue, David and Ed will highlight areas that need further work and possible approaches that could taken to further advance progress. As a pioneer in IP-based production, Suitcase TV will share its ongoing experiences, both good and bad, of using IP with broadcast signals and look at why it is worth the pain.

  • What has changed in the past 12 months?
  • What new opportunities can we as an industry take from the standards?
  • What new developments are now possible?

Ample time will be available for discussion so bring your experiences, questions and answers.
