Video: CHUNKY MONKEY – using chunked-encoded chunked-transferred CMAF to bring low latency live to very large scale audiences

Posted on by Russell Trafford-Jones

Will Law from Akamai proves his chunky credentials by telling us how to achieve very low-latency streaming in his talk at Demuxed 2018.

In the jungle of solutions for low latency live streaming, there are many current options ranging from WebRTC, to proprietary UDP protocols to standard segmented media with ever-shortening segments. This session highlights one of these – chunked-encoded chunked-transferred CMAF – as an optimal and practical confluence of both reach and performance. On the technical side, we’ll investigate the underlying technology, the latency regimes possible, compatibility with legacy players, cachability on delivery networks and player behaviour requirements. Including live demonstrations of several streams on a production network. This talk looks at the standards from DVB and MPEG DASH as well as CDN support. As a sweetener, Will points you at open source code on both the encoder and player side for doing this all yourself.

Video: Visual Excellence in Production

Posted on by Russell Trafford-Jones

In this Tech Talk we shall hear from researchers and vision scientists, how they are ensuring the precision of HDR and colour in image capture.

Today’s imaging technology strives to produce a viewing experience which is, as far as possible, identical with that perceived by the human visual system. Strangely, one limiting factor in high dynamic range (HDR) design has been that existing measurements of the human vision have not been sufficiently accurate. Another of these issues is skin tone: humans are particularly sensitive to skin colour – regarding it as an indicator of well-being. The accurate portrayal of this subtle parameter is therefore particularly important. A further interesting image quality issue is slow motion – here we explore the development of an 8K UHD 240fps camera and slow motion capture and replay server.

Video: Audio Network Standards AES67 and SMPTE ST2110

Posted on by Russell Trafford-Jones

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.

Video: Architecting a media virtual network function (VNF) for broadcast services

Posted on by Russell Trafford-Jones

This technical presentation from Carl Petch of Telstra Broadcast Services looks at some of the reasons why broadcast providers are moving to virtualization, and what the benefits are of applying virtualization to broadcast workflows. Carl explains the vendors they used, the way they architected their solution and some lessons learnt!
