Versatile Video Coding (VVC), also known as H.266,[1] ISO/IEC 23090-3,[2] and MPEG-I Part 3, is a video compression standard finalized on 6 July 2020, by the Joint Video Experts Team (JVET),[3] a joint video expert team of the VCEG working group of ITU-T Study Group 16 and the MPEG working group of ISO/IEC JTC 1/SC 29. It is the successor to High Efficiency Video Coding (HEVC, also known as ITU-T H.265 and MPEG-H Part 2). It was developed with two primary goals – improved compression performance and support for a very broad range of applications.[4][5][6]

Concept[]

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 standard has about 50% better compression rate for the same perceptual quality, with support for lossless and subjectively lossless compression. It supports resolutions ranging from very low resolution up to 4K and 16K as well as 360° videos. VVC supports YCbCr 4:4:4, 4:2:2 and 4:2:0 with 8–10 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. Work on high bit depth support (12 and 16 bits per component) started in October 2020[7] and is ongoing. 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 about twice that of HEVC.

VVC development has been made using the VVC Test Model (VTM), a reference software codebase that was started with a minimal set of coding tools. Further coding tools have been added after being tested in Core Experiments (CEs). Its predecessor was the Joint Exploration Model (JEM), an experimental software codebase that was based on the reference software used for HEVC.

History[]

JVET issued a final Call for Proposals in October 2017, and the standardization process officially began in April 2018 when the first working draft of the standard was produced.[8][9]

At IBC 2018, a preliminary implementation based on VVC was demonstrated that was said to compress video 40% more efficiently than HEVC.[10]

The content of the final standard was approved on 6 July 2020.[11][12][13]

Schedule[]

  • October 2017: Call for Proposals
  • April 2018: Evaluation of the proposals received and first draft of the standard[14]
  • July 2019: Ballot issued for Committee Draft
  • October 2019: Ballot issued for Draft International Standard
  • 6 July 2020: Completion of final standard

Licensing[]

To reduce the risk of the problems seen when licensing HEVC implementations, for VVC a new group called the Media Coding Industry Forum (MC-IF) was founded.[15][16] However, MC-IF had no power over the standardization process, which was based on technical merit as determined by consensus decisions of JVET.[17]

Four companies were initially vying to be patent pool administrators for VVC, in a situation similar to the previous AVC[18] and HEVC[19] codecs. Two companies were later reported to be forming pools: Access Advance and MPEG LA.[20]

Adoption[]

Software[]

Encoders/decoders

  • Fraunhofer HHI released an open source VVC encoder called VVenC[21] and an open source decoder called VVdeC[22][1]
  • VVC VTM reference software
  • Tencent Media Lab supports VVC in a real time decoder[23] and the Tencent Cloud service supports it with transcoding and streaming in its cloud infrastructure.[24]

Players

  • Spin Digital sells a real time VVC decoder and player for Linux and Windows devices.[25]
  • MX Player[26] was reported to deliver content in VCC to up to 20% of its mobile customers.[27]

No change to the standardization has been done, so it could theoretically happen that the same thing with HEVC happens again. No measures have been done to prevent that, unfortunately.
