H.266/VVC Standard Finalized With ~50% Lower Size Compared To H.265
The Versatile Video Coding (VVC) standard is now firmed up as H.266 as the successor to H.265/HEVC.
[...] Fraunhofer won't be releasing H.266 encoding/decoding software until this autumn. It will be interesting to see meanwhile what open-source solutions materialize. Similarly, how H.266 ultimately stacks up against the royalty-free AV1.
Through a reduction of data requirements, H.266/VVC makes video transmission in mobile networks (where data capacity is limited) more efficient. For instance, the previous standard H.265/HEVC requires ca. 10 gigabytes of data to transmit a 90-min UHD video. With this new technology, only 5 gigabytes of data are required to achieve the same quality. Because H.266/VVC was developed with ultra-high-resolution video content in mind, the new standard is particularly beneficial when streaming 4K or 8K videos on a flat screen TV. Furthermore, H.266/VVC is ideal for all types of moving images: from high-resolution 360 video panoramas to screen sharing contents.
Versatile Video Coding (VVC/H.266):
In October 2015, the MPEG and VCEG formed the Joint Video Exploration Team (JVET) to evaluate available compression technologies and study the requirements for a next-generation video compression standard. The new algorithms should have 30-50% better compression rate for the same perceptual quality, with support for lossless and subjectively lossless compression. It should support resolutions from 4K to 16K as well as 360 videos. VVC should support YCbCr 4:4:4, 4:2:2 and 4:2:0 with 10 to 16 bits per component, BT.2100 wide color gamut and high dynamic range (HDR) of more than 16 stops (with peak brightness of 1000, 4000 and 10000 nits), auxiliary channels (for depth, transparency, etc.), variable and fractional frame rates from 0 to 120 Hz, scalable video coding for temporal (frame rate), spatial (resolution), SNR, color gamut and dynamic range differences, stereo/multiview coding, panoramic formats, and still picture coding. Encoding complexity of several times (up to ten times) that of HEVC is expected, depending on the quality of the encoding algorithm (which is outside the scope of the standard). The decoding complexity is expected to be about twice that of HEVC.
