Video: Into the Depths: The Technical Details behind AV1

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: The state of advanced codecs; separating hype from reality

There are a lot of codecs both new and old that are in use or vying to be the next big thing. Tom Vaughan helps us see what they really can achieve and where each one is useful.

Recorded at San Francisco Video Tech Meetup in September, this video starts with a look at a the ‘hype cycle’. Tom places each codec, from MPEG 2 to VVC on the curve before looking at what the barriers to adoption are.

Tom then looks at HEVC discussing which devices can receive it, which can create it, the streaming services which support it and where adoption is likely to be. Finally, HEVC discussion is complete without a look at the HEVC patent landscape Venn diagram.

The focus then shifts to the Alliance for Open Media and their AV1 codec, its patent status and technical progress to date. He then discusses the performance of AV1, HEVC and Beamr against each other.

Almost brand new out of the starting blocks is VVC from MPEG and the Media Coding Industry Forum (MC-IF). Tom explains the aims of the forum and the VVC codec they are creating before taking questions from the floor.

Top Video of 2018: HEVC vs AV1 and the Future of the Codec Battle

 

As the first post of 2019, please allow me to say Happy New Year and to thank you for the time you spend coming to the website, following by email and/or following on social media. Your visits, interest and recommendations are very important and highly appreciated. 2018 ended with being nominated for the Royal Television Society Website of the Year. Whilst the hardworking and knowledgable people at The Broadcast Bridge won, and deservedly so, I hope you’ll be as mighty pleased as I was to see a non-commercial site pitted against the best in the industry. Be assured that The Broadcast Knowledge always aims higher than before so what better motivation than to top that!

As we set our sights on 2019, there’s time for a brief look back at the top video linked to here on The Broadcast Knowledge in 2018. Looking back at the stats, it has the most page visits and the most clicks, so let’s revisit this panel on AV1 and HEVC. It’s not often you get the likes of Facebook and Harmonic sharing their latest research on stage with companies like Harmonic and Bitmovin who are very active in the Codec community, so it’s no surprise this piqued the interest of many.

This panel took place during NAB 2018 when AV1 had just ‘released’ the AV1 codec at the show but the points discussed are as relevant today as they were then including the adoption of HEVC in the marketplace. Having said that, do check out the AV1 and HEVC tags to see what more recent discussions there have been including a discussion of the future of video codecs at Streaming Media East 2018

Sit back and watch HEVC vs AV1 and the Future of the Codec Battle!

Video: HEVC Vs AV1 and the Future of the Codec Battle

In this debate from NAB 2018, the panel discusses the video codecs which are competing to be the next-generation standard in the OTT environment and, notably, HEVC and AV1 being the front-runners. The debate on which video standard is best suited to our industry is in full swing especially as the Alliance for Open Media released AV1 at the NAB Show and Apple is supporting HEVC in its products and has decided to join the Alliance for Open Media as a founding member. This panel discusses the pros and cons of HEVC and AV1, and also put in perspective content-aware encoding techniques with AVC that might be a strong challenger in the short term for OTT distribution.

Webinar: Online Video Formats: 2018 and Beyond


Webinar: Tue, Mar 27, 2018 6:00 PM – 7:00 PM BST
Sifting through the plethora of online codecs current and upcoming, Jason Thibeault and Thierry Fautier present this webinar from Harmonic and the Streaming Video Alliance

Recently, we have seen renewed attention on HEVC following Apple’s announcement to support the codec on their devices. 6 months later, Apple surprisingly became a founding member of the Alliance for Open Media (AOM) as a supporter of the AV1 codec. Yet, while the AOM group claims AV1 provides better performance than HEVC and will be offered royalty-free, there are some academic benchmarks who find AV1 inferior to HEVC on codec quality and performance.
In the meantime, MPEG / ITU-T is working on a next generation video codec, in a group called JVET (Joint Video Exploration Team) that has a mandate to deliver a video compression standard that can reach 50% over HEVC in 2020. Additionally, on the streaming side, we have seen the MPEG CMAF standard getting some traction not only to unify the HLS and DASH worlds, but also to offer the long awaited low latency delay solution for OTT.

This panel will discuss perspectives on these video compression technologies to help content providers, broadcasters, and service providers figure out the best path forward to distribute content over the internet in the coming years.
