Abstract
A video coding device may receive a video bit-stream that carries a video captured in a non-4:4:4 chroma format. A palette mode may be used to decode the video bit-stream. The video bit-stream may include data defining a palette table and a palette index map in a 4:4:4 chroma format for the current block. A luma sample value for a luma sample position in the non-4:4:4 chroma format may be determined based on the luma sample position, the palette index map and the palette table. A chroma sample position associated with the 4:4:4 chroma format on the palette index map may be derived based on the luma component to chroma component resolution ratio in the non-4:4:4 chroma format. A chroma sample value for a chroma sample position in non-444 chroma format may be determined based on the derived chroma sample position, the palette index map and the palette table.
