1Productivity
If existing video coding technologies (MPEG-2, MPEG-4, H.263, H.264, HEVC, VVC) are used, then video compression is achieved, but coding efficiency needs further improvement
Solution Approach 1:
The patent merges intra template matching prediction with other coding tools to create a unified prediction framework. This combination allows the system to leverage the strengths of multiple approaches, achieving both improved coding efficiency and maintained reliability by selecting the best prediction method for each block based on template matching results

AI summary
Embodiments of the disclosure provide a solution for video processing. A method for video processing is proposed. The method includes: deriving, for a conversion between a video unit of a video and a bitstream of the video, a prediction or reconstruction of the video unit based on one of: one or more intra template matching prediction (intra TMP) candidates, one or more intra prediction modes (IPMs), one or more reordered intra TMP candidates, or one or more reordered IPMs, and wherein the video unit is applied with a fusion of intra template matching prediction (intra TMP) mode and a coding tool; and performing the conversion based on the prediction or reconstruction of the video unit.
