Abstract
An electronic apparatus performs a method of decoding video data. The method comprises: receiving, from the bitstream, a plurality of syntax elements associated with a coding unit, wherein the plurality of syntax elements indicate the coding tree type of the coding unit, and whether the local dual tree mode is enabled for the coding unit; and in accordance with the determination that the coding tree type of the coding unit is a single tree, and the local dual tree mode is enabled for the coding unit: disabling the palette mode for the coding unit when the coding unit has the size equal to or less than a predefined threshold. In some embodiments, disabling palette mode for the coding unit includes: disabling the palette mode for both the luma component and chroma component of the coding unit, or disabling the palette mode for only the chroma component of the coding unit.
