Institute of Telecommunications Fraunhofer HHI officially unveiled a new codec called H.266 / Versatile Video Coding (VVC). Over time, it should replace the H.265 / HEVC codec, which is now widely used in Apple devices.
Fraunhofer HHI notes that while the H.265 / HEVC codec requires about 10 GB of data to create a 90-minute 4K UHD video, H.266 / VVC will need only 5 GB of data for the same task. In this case, the video quality will remain unchanged.
The full specifications of the H.266 / VVC codec are described on more than 500 pages. The main thing you need to know is that it is designed to create high-resolution content – 4K and 8K. Thus, users will be able to take much more photos and record more videos in high quality, which will take up less space, and therefore consume less traffic when sending content.
However, the large-scale implementation of H.266 / VVC will have to wait 7-8 years. At the moment, the H.264 / AVC codec, introduced in 2003, is still very popular. The first versions of the H.265 / HEVC codec were ratified in January 2013 (although the first developments appeared back in 2010), and Apple announced its implementation in iOS 11 only in September 2017. Only recently, graphics cards on Macs began supporting HEVC's advanced hardware acceleration.
But, in any case, the H.266 / VVC codec promises significant progress, so we will wait for further information on plans for its implementation.
