Abstract

Although a video encoding device multiplexes ctu_pcm_flag syntax indicating whether all image blocks belonging to a coding tree unit as a set of image blocks are PCM blocks, at the top of the coding tree unit, when all image blocks belonging to the coding tree unit are PCM blocks, at least cu_split_flag syntax indicative of the splitting pattern of the coding tree unit is not multiplexed to transmit PCM data efficiently.
