Video: Routing AES67

Well ahead of video, audio moved to uncompressed over IP and has been reaping the benefits ever since. With more mature workflows and, as has always been the case, a much higher quantity of feeds than video traditionally has, the solutions have a higher maturity.

Anthony from Ward-Beck Systems talks about the advantages of audio IP and the things which weren’t possible before. In a very accessible talk, you’ll hear as much about soup cans as you will about the more technical aspects, like SDP.

Whilst uncompressed audio over IP started a while ago, it doesn’t mean that it’s not still being developed – in fact it’s the interface with the video world where a lot of the focus is now with SMPTE 2110-30 and -31 determining how audio can flow alongside video and other essences. As has been seen in other talks here on The Broadcast Knowledge there’s a fair bit to know.(Here’s a full list.

To simplify this, Anthony, who is also the Vice Chair of AES Toronto, describes the work the AES is doing to certify equipment as AES 67 ‘compatible’ – and what that would actually mean.

This talk finishes with a walk-through of a real world OB deployment of AES 67 which included the simple touches as using google docs for sharing links as well as more technical techniques such as virtual sound card.

Packed full of easy-to-understand insights which are useful even to those who live for video, this IP Showcase talk is worth a look.

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!

Webinar: IP for Media Part 4 – Audio

Date: Thursday 21st March 2019
Time: 2PM EDT / 18:00 GMT

The fourth in the series of IP in broadcasting, Wes Simpson, NewTek and TV Technology are back, this time, to discuss using Audio over IP – specifically uncompressed audio over IP.

There are a number of proprietary systems like Dante, RAVENNA and others, but this webinar focusses on the standardised AES67 and the closely linked SMPTE ST 2110-30 standards.

Register here for this webinar and the previous IP ones which cover Security, Remote Production and the first ‘101’ session covering the basics of compressed and uncompressed IP for broadcasting.

Video: AES67 Open Media Standard for Pro-Audio Networks

AES67 is a method of sending audio over IP which was standardised by the Audio Engineering Society as a way of sending uncompressed video over networks between equipment. It’s become widespread and is part of SMPTE’s professional essences-over-IP standards suite, ST 2110.

Here, Conrad Bebbington gives us an introduction to AES67 explaining why AES67 exists and what it tries to achieve. Conrad then goes on to look at interoperability with other competing standards like Dante. After going into some implementation details, importantly, the video then looks the ‘Session Description Protocol’, SDP, and ‘Session Initialisation Protocol’, SIP which are important parts of how AES67 works.

Other topics covered are:

  • Packetisation – how much audio is in a packet, number of channels etc.
  • Synchronisation – using PTP
  • What are SDP and SIP and how are they used
  • Use of IGMP multicast
  • Implementation availability in open source software

Video: Audio Network Standards AES67 and SMPTE ST2110

This is a very accessible overview of AES67 and 2110 from Andreas Hildebrand, evangelist for RAVENNA audio over IP technology at ALC Networx.

Andreas explains what SMPTE 2110 and AES67 are and how they relate to other standards in the industry. He then looks at the timing requirements of 2110 and how they differ to those of AES67 with examples. Another important area examined is when 2110’s audio is/isn’t compatible with AES67.

Finally AES3 is discussed as this is part of the ST 2110-31 standard and Andreas shows how this relates to RAVENNA standards.

Two presentations from BBC Research and development, by Chris Baume and Jamie Laundon at a joint event from AES South and SMPTE South Section.

Chris Baume: The Mermaid’s Tears – creating the world‘s first live interactive object-based radio drama

Object-based audio is a revolutionary approach to broadcasting that enables the production and delivery of immersive, interactive and accessible listening experiences. Chris will start by presenting an overview of the opportunities and challenges of object-based audio. He will describe how BBC R&D designed and built an experimental radio studio and an end-to-end object-based broadcast chain. Finally, he will discuss how the studio was used to deliver the world’s first live interactive object-based radio drama, as part of the Orpheus collaborative project.

Chris Baume is a Senior Research Engineer at BBC R&D in London, where he leads the BBC’s research into audio production tools and the BBC’s role in the Orpheus EU H2020 project. His research interests include semantic audio analysis, interaction design, object-based audio and spatial audio. Chris is a Chartered Engineer and a PhD candidate at the Centre for Vision, Speech and Signal Processing at the University of Surrey.

Jamie Laundon: Audio over IP and AES67 – learning to play nicely together

As AoIP becomes commonplace across the industry, the BBC’s Jamie Laundon provides an informative summary of the current state of IP audio in the radio studio, how the latest update to AES67 improves interoperability, and how Plugfests are used to identify and resolve issues between different systems. He will also walk us through an example installation to discuss the various options and decisions you need to make to make your next installation fully IP.

Jamie Laundon is a Senior Technologist at BBC Design and Engineering. He delivers complex technology projects for the BBC’s national radio networks, with a focus on connectivity, workflow design, metadata and networked audio. His 16 year radio career began within UK commercial radio at Heart and LBC in London, before becoming Technical Manager at Galaxy Radio in Yorkshire. He later joined Radio Computing Services (RCS) as an integration specialist working with radio networks across Europe and the Middle East. Jamie is a member of the Engineering innovation team researching BBC Radio’s next-generation “Internet Fit Radio Studios”, with a focus on networked audio interoperability.
