Version 2.0 of xvc released with improved compression performance and a royalty-free baseline
Posted 2018-07-03

Divideon has just released a new version of the xvc video codec. The official press release is available here. Version 2.0 of xvc includes new tools for improved compression performance and a royalty-free baseline profile. The xvc software is publicly available at GitHub under a dual licensing scheme; an LGPL license and a commercial license. And even though the codec and the software has been extended with new compression tools and new features such as multi-threaded encoding, xvc’s extensible bitstream structure and versioning framework ensures that all version 1 bitstreams are fully compatible and decodable by version 2 decoders.

 

The xvc codec wins price and stands strong against AI-empowered image compression schemes
Posted 2018-06-07

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
Posted 2018-05-18

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
Posted 2018-03-07

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
Posted 2018-02-09

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 xvc-licensing@divideon.com if they believe that they hold patents that read on xvc.

 

New xvc demo shows the quality improvement of deploying xvc
Posted 2018-01-24

Since the first day when the xvc codec was released it has been clear that it is the world’s most efficient video codec, and it is constantly improving (in the dev branch of the xvc repository). But xvc does not only come with the best compression performance, it also comes with a lightweight decoding process and an efficient reference decoder implementation. The decoding process is actually so light that it can be run in JavaScript directly in browsers, without requiring any plug-ins or preinstalled applications. Sounds to good to be true? Try it out yourself, at our mobile video streaming with xvc page where we demonstrate the quality improvement that can be achieved when switching your mobile streaming service from h.264 to xvc.

 

The xvc codec in the news
Posted 2017-12-11

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
Posted 2017-10-10

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.

Compression beyond HEVC at the MPEG meeting
Posted 2017-08-14

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.
