The xvc codec wins price and stands strong against AI-empowered image compression schemes
The xvc codec is not only a very capable video compression format – which outperforms all other available video codecs (link) – it is also an extremely competent image compression format. This is recognized at the Conference on Computer Vision and Pattern Recognition (CVPR) 2018 where xvc has been announced as one of the winners in the challenge on learned image compression. The focus of the challenge, and the associated workshop, is on using Artificial Intelligence (AI) and Machine Learning (ML) techniques for image compression, but traditional approaches have also been welcomed to participate. The xvc codec has been designed for real-time decoding, typically at 30 frames per second or more, and does so far not include any elements of AI or ML. Nevertheless, the xvc codec provides better subjective quality than all other tested codecs, except for one, compared to which it falls short by only 0.007 in Mean Opinion Score (MOS) as can be seen at the challenge results page. But an important aspect to highlight is xvc’s fast decoding time. The xvc codec is between 29 times faster and 209 times faster compared to the other top performing schemes, which can explain why it’s awarded the price for fastest top entry.
Technical work towards new MPEG standard – and next version of xvc on it’s way
The MPEG standardization group (part of ISO/IEC) has kicked of technical work in a collaborative project together with VCEG (part of ITU-T) called JVET, and is aiming for publishing a new international video coding standard in late 2020. You can read more about the project at the MPEG convenor’s blog. A lot of new interesting technology will be evaluated in the context of the JVET project and Divideon is taking part in both technical and non-technical discussions and is continuing to work actively for reasonable licensing terms and rapid adoption of new technology for the benefit of the industry and the consumers. We are also continuing the work on the xvc codec, and the preparation for the second version of xvc is ramping up. Version two of xvc will provide better compression performance and include additional functionality, such as multi-threaded encoding – a feature that can already be turned on in the dev branch of the xvc repository by using the ‘-threads’ parameter.
The xvc codec at the IETF meeting – and new results for xvc
The xvc codec has been submitted to the NETVC Working Group of IETF as a candidate proposal and will be presented at the 101st IETF meeting in London. The submission, which is available here, includes a high-level description of xvc as well as performance numbers comparing a recent revisions of xvc with recent revisions of AV1 and HEVC. The performance page at the xvc website has been updated to include examples and illustrations of the new results. From the results, it can be noted that xvc is a clear overall winner and that xvc delivers extraordinarily good performance at lower resolutions (360p), with average bitrate savings relative to AV1 of 20% for single pass encoding and 16% for multi-pass encoding.
Divideon issues Call for Patents in xvc
Efficient video compression involves a large number of advanced processing steps applied to reduce video bandwidth as much as possible, without compromising visual quality. Developing and optimizing those processing steps requires a lot of hard work and throughout the years, a large number of organizations have been engaged in such development. Some combinations of processing steps, have been patented by the organization that have developed them, and at Divideon we are determined to share the licensing income from xvc with anyone that holds patents which read on xvc. We are already in contact with many organizations that have been involved in video compression technology development, but we are now also issuing a formal Call for Patents in xvc, in order to reach out to those that we might not previously have been in contact with. The Call for Patents in xvc is available here and patent holders are requested to contact email@example.com if they believe that they hold patents that read on xvc.
New xvc demo shows the quality improvement of deploying xvc
The xvc codec in the news
The xvc codec has now been available for a few months and it is starting to gain traction in the media streaming industry. An article about xvc can be found in the November/December 2017 issue of Streaming Media Magazine with the title “A Better HEVC Codec?”. The article is also available online here. The article summarizes some of the most central aspects of xvc and the xvc licensing model. There is also a short section around quality and compression performance relative to other codecs such as HEVC and AV1, mentioning that “in the two real-world files, xvc was the quality leader”. The article ends by emphasizing that “It’s definitely early days, but xvc appears to be a codec you should keep your eye on.”. The xvc codec was also one of the topics discussed at the Streaming Tech Sweden conference, where Divideon’s Jonatan Samuelsson presented about HEVC and xvc (slides available here).
Continued development of xvc
The first version of xvc was released less than a month ago but work towards the next version of xvc has already commenced. If you want to take a closer look at the development, or even start contributing to xvc, please check out https://github.com/divideon/xvc/tree/dev. Next week, Divideon will attend the MPEG meeting in Macau to present about xvc – and we are looking forward to valuable and fruitful discussions together with some of the world’s leading experts on video compression.
Introducing xvc – a world class video codec with indemnification
We are extremely proud to announce the release of xvc – a novel video codec with a revolutionary licensing model. The xvc codec is a software defined video codec with unprecedented performance, developed by Divideon. Please read the official press release for further details. Feel free to contact us if you have questions around xvc or if you would like to meet up and see our real-time xvc software decoding demo. We will be at IBC in Amsterdam from September 14 to September 18, send an email to firstname.lastname@example.org to schedule a meeting. At xvc.io you will find the source code of xvc and additional information about the codec and the one-stop shop license. We have also uploaded a white paper with background information about xvc.
Compression beyond HEVC at the MPEG meeting
Divideon attended the MPEG meeting in Turin in July 2017. One of the most interesting developments was in the area of video compression beyond HEVC. A Call for Evidence had been issued and it could be determined that there is technology showing improved performance relative to HEVC. The MPEG community is now taking the first steps towards starting a new project together with VCEG in developing a successor to HEVC. Divideon is actively taking part in this work, with a focus on making a future compression format broadly accessible, with extraordinary performance on low-bitrate streaming applications. An official press release from the MPEG meeting can be found at http://mpeg.chiariglione.org/meetings/119.
Divideon joins MPEG
Divideon is now a proud member of the MPEG community, joining forces with the largest and most productive video codec community in the world. MPEG has a remarkable history of producing media coding standards used all over the world, such as MPEG-2, AVC (MPEG-4 Part 10) and HEVC. MPEG meetings are being held four times per year with the next one scheduled for Torino in July 2017 (check out the MPEG website for more info). Would you like to meet up with us in Torino and learn more about Divideon, please send an email directly to email@example.com.
New Divideon website
Finally, a proper website for Divideon has been created. You can now find a little bit more information about Divideon, and we will continuously add more information about the company and the progress of our product development. Stay tuned to make sure you do not miss out on anything, or sign up for our newsletter so that you always get the latest news first.
