AV1 implementations are still being worked on along a number of fronts and the business cases are starting to shake out. Here’s a developer-focussed look at AV1 from patents to the way it works and to lessons learnt implementing it.
It was last year that the Alliance for Open Media released its next-generation video codec AV1. It achieves better compression than proprietary competitors, while its patents can be licensed via a royalty-free, open-source friendly license. With a broad array of industry support including all major browser vendors, many hardware partners, internet streaming video and conferencing providers, many think this is the best chance yet to create a successful video codec of its type that achieves wide deployment.
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
Thierry Fautier, speaking at SMPTE 2017, explains the planned advances in Codecs for the next 5 years explaining the new techniques and likely future abilities of the different codecs. Based on his technical paper, Thierry explains efforts to ‘boost’ HEVC and, in the future JVET which complements his comprehensive look across VP9, HEVC, AVC, JVET and AV1.
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.
