The Versatile Video Coding (VVC) is the most recent video coding standard jointly developed by MPEG (ISO/IEC) and VCEG (ITU-T) in the JVET (Joint Video Experts Team).
The VVC Final Draft International Standard was issued in mid-2020. VVC can be considered as the state-of-the-art video coding standard, with an estimated bitrate gain around 40% versus the High Efficiency Video Coding (HEVC).
VVC has been developed incrementally based on the HEVC design, with the introduction of multiple new coding tools in all building blocks of the codec architecture. This paper aims at providing an overview of VVC by highlighting the main differences compared to HEVC.
It reports a compression performance analysis, based on the coding gain evaluation of each tool for various contents (including contents not used in JVET). The analysis also considers the impact of the tools in terms of encoding and decoding complexity. Global performance measures with regards to HEVC are provided in different encoding configurations and picture formats.
