Abstract
A method of decoding video data is performed by an electronic apparatus. The electronic apparatus receives, from a video bitstream, one or more syntax elements indicating that a coding block is coded under a palette mode. The electronic apparatus divides the coding block into multiple segments, each of the multiple segments having a set of index values that is independent from another one of the multiple segments. The electronic apparatus receives, from the video bitstream, index values associated with each of the multiple segments and a palette table associated with the coding block and decodes the multiple segments in parallel according to the index values and the palette table associated with the coding block.
