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: 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.

Video: Deep Dive into SMPTE ST 2110-30, 31 & AES 67 Audio

Despite the title, a relatively light and short video for the weekend from NAB on using audio in 2110.

Why is there a separate SMPTE ST 2110-30 standard from AES67? Are AES67 devices compatible with SMPTE ST 2110-30? Why is there a SMPTE ST 2110-31 standard? This presentation from Leigh Whitcomb (Architect, Imagine Communications) is a deep dive into the SMPTE ST 2110-30, 31 and AES67 audio and will answer all these questions.
