Low latency streaming is always a compromise, but what can be done to keep QOE high?
This on-demand webinar looks at CMAF and presents some real-world data on this low latency technique. The webinar starts by explaining that CMAF is a low-latency streaming technology similar to HLS and other streaming protocols where the idea is to deliver the video as small files. Olivier and Alain from Harmonic explain how this is done and look at some of the trade-offs and compromises that are needed and introduce techniques to keep QOE high. They also look at deployment in cloud vs. on premise.
Pieter-Jan Speelmans talks about play tradeoffs and optimisations within the player. CMAF allows the buffer to be reduced and whilst a bad network may mean you buffer is similar to ‘normal’, but in good networks, this buffer can be brought down significantly. He also talks about how ABR switching is impacted by GOP length even in CMAF.
Viaccess-Orca explains how DRM works with CMAF and looks at some of the challenges including licences acquisition time and overloading licence servers at the beginning of events. Akamai’s Will Law explains some benefits of CMAF and the near-real-time of chunk-based transfer (HTTP 1.1) and how downloading chunks at full speed leads to problems when the same broadband link is used by several clients.
There are lots of good talks on CMAF, but this is one of the few which talks about CMAF not as theory, but as is deployable today.
There are many ways to speed up live streaming and much work has gone in to reducing chunk lengths for HLS-style streaming, WebRTC has arrived on the scene and techniques to speed up chunk delivery are in production in CDNs around the world.
But we shouldn’t forget lower down in the detail, we have how the web sites are actually saved to customers – the venerable HTTP. Running on TCP/IP, HTTP packets are delivered using very thorough acknowledgement mechanisms within TCP/IP. Furthermore, it’s immune to spoofing attacks due to a three way handshake to set up the connection.
However, all this communication ads latency as even for low latency connections, these communications can add up to a significant latency and affect the speed of the throughout of the connection.
This talk introduces QUIC which is a replacement for HTTP developed by Google which uses UDP as its underlying delivery mechanism, thus avoiding much of this built-in two way comms.
At the Mile High Video event, Miroslav Ponec from Akamai introduces this protocol which is undergoing standardisation at the IETF explaining how it works and why it’s such a good idea.
Akamai brings together GamesBeat, Ubisoft and Gen.G to talk about how to monetise esports. Gen.G runs esports teams, Ubisoft makes games, GamesBeat reviews games and Akamai delivers esports streaming. So together they have a pretty good idea of the industry!
Questions covered are:
What are the current esports revenue models?
Where is the bulk of revenue coming from today?
What lessons can be learned from traditional sports models?
How does Monetisation differ between East and West?

For many content providers and rights-holders, live streaming represents an exciting opportunity to connect directly with their target audiences plus drive new revenue streams.
This webinar discusses topics including the pros and cons of live streaming as compared with broadcasting, how to measure quality of experience and reliability, which business models are being used, current best practices, ongoing challenges, critical initiatives, and much more.
Join Alec Hendry, Senior Director of Technology Convergence for Viacom, Will Richmond, Editor and Publisher at VideoNuze, and Henrik Eriksson, Service Line Manager at Akamai, for a roundtable discussion covering:
The state of live streaming today
How to measure quality in live streaming and ensure a positive user experience
Successful business models for live streaming
Best practices associated with live streaming
Senior Director of Technology Convergence,
As security continues to be forefront in broadcasters’ minds, Akamai continues to monitor internet security threats. Herem they tell you what to expect in the year to come as they review the biggest events and best research from Akamai’s 2018 State of the Internet / Security: A Year in Review report.
Why low-and-slow, high-leverage application-level attacks can be just as damaging as high-bandwidth attacks
How specialisation among adversaries is driving marketisation and economies of scale in the hostile ecosystem of malicious actors
What the biggest attacks of the previous year, like memcached and the Mirai botnet, indicate about the evolution of reflection and
botnet attack vectors
What our researchers have uncovered over the past year about the dark side of APIs, emerging and popular adversarial tools, new vulnerabilities, and more
What security trends we can expect in 2019 and how attacks and threats will evolve in the year ahead
Nobody wants to find out about a big play or major news event on Twitter before they see it in their video stream, so reducing latency is crucial for OTT services’ success. Likewise, ultra-low latency is crucial for interactive streaming applications. Depending on your use case, a few seconds of latency might be fine, or you might need to try to hit that sub-second target.
Learn which technologies and solutions are best for your business, and make sure your viewers get their video on time, every time. In this webinar, you’ll learn the following:
Why it’s important to evaluate and improve latency end-to-end, including software and services, encoder, platform, and player
How to decide which technology and solution is best for your use case (e.g. CMAF, HLS/DASH, WebRTC, Websocket)
How chunked CMAF offers a standards-based approach that allows latency to be decoupled from segment duration
How chunked CMAF leverages existing CDN HTTP capacity to provide low-latency solutions at high scale
How WebRTC can be used to deliver live video sub-second latency at scale, and provide rich, interactive experiences for live streaming applications
How a single misconfigured component can undo any other effort to achieve low latency
How integrated solutions create new business opportunities for low latency interactive use cases
How to achieve low latency across all platforms and devices

OTT is just TV—or at least it should be. Viewers are looking to OTT services not simply as an add-on to broadcast or cable, but as a replacement. Akamai, Bitmovin and EZDRM join forces in this Streaming Media webinar to shed light on how to make your OTT service as reliable, robust, and feature-rich as broadcast or cable, as well as how to add features and functionality that the previous generation of TV simply can’t match.
Will Law from Akamai proves his chunky credentials by telling us how to achive 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 a 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 behavior requirements. Including live demonstrations of several streams on a production network. This talks brings a standards perspective from DVB and 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.
