摘要：
A method and an apparatus for parallel encoding and decoding of moving picture data are provided. The method includes decoding, from a bitstream, a syntax element indicating that a picture can be decoded using wavefront parallel processing and decoding encoded data of the picture. The step of decoding encoded data of the picture includes for a first coding block of a current CTU row encoded in a palette mode, predicting a palette table for the first coding block by using palette data from a first CTU of a previous CTU row and decoding the first coding block in the palette mode using the palette table predicted for the first coding block.
