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: The Audio Parts of ST 2110 Explained

At the IBC 2018 IP Showcase, Andreas Hildebrand explains how AES67 and 2110 work together and how technologies like Dante, RAVENNA and Livewire fit in.

While there are lots of resources for working with 2110 video, but this is one of the few which tackles Audio. Andreas covers one of the ‘gotchas’ in 2110 – the compatability requirements for AES within the standard. He then looks at the timing requirements of 2110 and how they differ to those of AES67 and finally discusses AES3 while explaining the ST 2110-31 standard.
