摘要

A video encoding device includes a transformer for transforming an image block, an entropy encoder (103) for entropy encoding transformed data of the image block transformed by the transformer, a PCM encoder (1070) for PCM encoding the image block, and a multiplexed data selector (109) for selecting output data of any one of the entropy encoder (103) and the PCM encoder (1070) for each image block. The PCM encoder (1070) embeds, at the beginning of PCM data, a subsequent_pcm_flag syntax indicating whether an image block of PCM data follows or not.
