Introducing the VVC video codec with the ability to reduce video volume up to 50%

News unit EMGblog.com: The German institute Fraunhofer HHI on Monday, July 6 2020 (July 16, 2019) announced that after years of research, the VVC (or H.266) video codec has been finalized Is. Fraunhofer attributed this achievement to cooperation with its industrial partners, including Apple, Ericsson, Intel, Huawei, Microsoft, Qualcomm and Sony knows. According to the claim of this institute, the new VVC standard has made significant progress in terms of compression, and compared to the previous standard – that is, HEVC (or H.265) – it can reduce the file size by about 50% while maintaining the image quality. Considering that almost 80% of all Internet traffic is related to streaming video, we can call the VVC codec a great achievement.

VVC codec increases the efficiency of video transmission in mobile networks (which face limitations in data capacity) by reducing data requirements. For example, the previous HEVC standard required 10 gigabytes of data to transmit a 90-minute video with UHD resolution. But according to Fraunhofer’s claim, only 5 gigabytes of data are needed to transmit the same video with the VVC codec. According to Fraunhofer, the new VVC codec is suitable for video of various resolutions – from SD to 8K – as well as 360-degree video, and can support HDR on all of these videos. Of course, since the VVC codec was developed considering video content with very high resolutions, the superiority of this standard will be more noticeable, especially in streaming 4K or 8K videos on a flat screen TV. Not to mention, the VVC codec is not only suitable for regular videos, but also for screen sharing and game streaming applications.

Benjamin Bross, head of the video coding systems group at the Fraunhofer Institute, said that the VVC codec was a source of pride for Fraunhofer, referring to spending about 3 years to develop this standard. According to Benjamin Brass, the use of video around the world will increase further due to the significant leap in coding efficiency in VVC. Also, the versatility of VVC makes this codec an attractive option for a wider range of video storage and transmission applications. Detlev Marpe, Head of the Video Coding and Analysis Department at the Fraunhofer Institute, while pointing out the key role of this institute in the development of previous video coding standards (including AVC and HEVC), expressed his satisfaction that currently more than 50% of Internet bits are produced with Fraunhofer technology.

Like previous standards, VVC also includes options that are exempt from intellectual property, such as the open source AV1 and EVC base implementations. According to Fraunhofer, a transparent and integrated licensing model based on the FRAND (fair, reasonable and non-discriminatory) principle is to be established for the use of standard VVC patents. In this regard, an assembly called MC-IF (Media Coding Industrial Assembly) has been formed. In addition to Fraunhofer, more than 30 companies and organizations are now members of MC-IF. New chips needed to use the VVC codec – such as chips in mobile devices – are in the design process. According to Thomas Schierl, one of the officials of Fraunhofer, the first software to support VVC (both encoder and decoder software) will be released by this institute in the fall of this year.

According to Fraunhofer, the VVC video codec is the result of at least 4 generations of international standards for video coding. The previous standards, AVC and HEVC, which were developed through Fraunhofer’s efforts, are currently active in more than 10 billion devices worldwide and account for more than 90% of the world’s total video bit volume. These two standards won 3 Engineering Emmy Awards for their significant role in the development of television technology.

It was in September 2017 that Apple with the unveiling of iOS 11, added HEVC codec support to this operating system. Currently, iDevices users have the option to use the previous H.264 codec by selecting the “most compatible” option in the device settings, but recording 4K video at 60 frames per second, as well as recording slow-motion video at 240 frames per second. Second, only possible with HEVC codec. How long it will take for the new VVC codec to become widespread remains to be seen, but it will certainly take time. We should not forget that despite the fact that the first version of the HEVC codec was released in January 2013, the old AVC codec still has a colorful presence in the industry.
