Inventors include Li, Xinwei; Liao, Ru-Ling; Chen, Jie; and Ye, Yan.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: Methods and systems implement fusion of intra TMP mode with other intra prediction modes that utilize adjacent samples, to improve prediction accuracy. A VVC- standard encoder and a VVC-standard decoder can configure one or more processors of a computing system to apply non-CCP modes on the template of the collocated luma block, and reorder non-CCP modes based on template matching cost; additionally reorder angular modes, such as a subset of efficient angular modes based on the template of the collocated luma block; prune non-CCP modes from the ordered list based on similarity; move a non-CCP mode of the reordered ordered list based on template matching cost difference relative to a predecessor; copy and reorder the ordered list of non-CCP modes once for each respective distinctly signaled chroma fusion mode; fuse a chroma DBV mode with a CCP mode; and select a least-cost reordered block vector for chroma DBV mode.
