Webinar: Transforming creative workflows: Making great content in the cloud

Posted on 18th April 2019 by Russell Trafford-Jones

Join IBC365 on Thursday 25 April at 4pm BST to explore why creators are turning to cloud to transform the way they make great content and how virtualised workflows are unlocking the ability to work in new ways: faster, more collaborative, more efficient and more creative.

This webinar goes inside some of the world’s leading content creators, production and post-production operations to hear how they are embracing cloud technology to transform the creative processes used to make, produce and deliver video.

The webinar will cover ways in which cloud is enabling more collaboration, access to more talent, round-the-clock working, more content security, and slicker workflows. There’s also a dose of reality, as the human and technology challenges and the potential pitfalls of virtualising creative workflows are explored.

Case studies focus on using cloud for:
•Streamlining content creation in the field
•Transforming production and post-production processes
•Efficient content delivery and backhaul

Video: Making Video Streams QUICer

Posted on 15th April 2019 by Russell Trafford-Jones

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.

Video: Into the Depths: The Technical Details behind AV1

Posted on 10th April 2019 by Russell Trafford-Jones

As we wait for the dust to settle on this NAB’s AV1 announcements hearing who’s added support for AV1 and what innovations have come because of it, we know that the feature set is frozen and that some companies will be using it. So here’s a chance to go in to some of the detail.

AV1 is being created by the AOM, the Alliance for Open Media, of which Mozilla is a founding member. The IETF is considering it for standardisation under their NetVC working group and implementations have started. On The Broadcast Knowledge, we have seen explanations from Xiph.org, one of the original contributors to AV1. We’ve seen how it fares against HEVC with Ian Trow and how HDR can be incorporated in it from Google and Warwick University. For a complete list of all AV1 content, have a look here.

Now, we join Nathan Egge who talks us through many of the different tools within AV1 including one which often captures the imagination of people; AV1’s ability to remove film grain ahead of encoding and then add back in synthesised grain on playback. Nathan also looks ahead in the Q&A talking about integration into RTP, WebRTC and why Broadcasters would want to use AV1.

Video: HEVC/H.265 Video Coding Standard

Posted on 9th April 2019 by Russell Trafford-Jones

HEVC, also known as H.265 is often discussed even many years after its initial release fro MPEG with some saying that people aren’t using it and others saying its gaining traction. In reality, both sides have a point. Increasingly HEVC is being adopted partly because of wider implementation in products and partly because of a continued push toward higher resolution video which often gives the opportunity to make a clean break from AVC/H.264/MPEG 4.

This expert-led talk looks in detail at HEVC and how it’s constructed. For some, the initial part of the video will be enough. Others will want to bookmark the video to use as reference in their work, whilst still others will want to watch the whole things and will immediately find it puts parts of their work in better context.

Wherever you fit, I think you’ll agree this is a great resource for understanding HEVC streams enabling you to better troubleshoot problems.
