Description
To identify relevant patents, comprehensive searches were conducted across multiple patent databases using a combination of search strings, IPC/CPC classifications, and VVC–specific keywords. Since the VVC standard was officially published in August 2020, the search focused exclusively on patents with a priority date on or before August 2020.
The development of VVC was marked by a surge in patent activity, particularly between 2017 and 2020, as researchers raced to contribute novel techniques that would define the future of video compression. These patents underpin a wide array of sophisticated coding tools introduced in the standard, including quad-tree plus multi-type tree (QTMT) block partitioning, advanced intra/inter prediction, affine motion compensation, and transform skip techniques, all of which collectively enable up to 50%-bit rate reduction over HEVC for the same visual quality.
