Patent attributes
Methods, systems, and devices for using palette mode with different partition structures are described. An example method for video processing includes maintaining, for a conversion between a video comprising one or more video regions comprising a current video block and a bitstream representation of the video, a palette prediction table for a prediction of a palette used in a palette mode coding tool used for the current video block, making a determination that a local dual tree coding is applied to the conversion, modifying, based on the determination, the palette prediction table, and performing, based on the palette prediction table subsequent to the modifying, the conversion, wherein the palette mode coding tool represents the current video block using a palette of representative color values, and wherein the local dual tree coding enables partitioning of chroma blocks independently from corresponding luma blocks based on a block size.
