    Abstract: 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.

    Abstract: A video encoding device includes a down-sampler with sampling position shifter 107 configured to down-sample a luminance signal, and a predictor 101 configured to linearly predict a color difference signal from a down-sampled luminance signal. The down-sampler with sampling position shifter 107 shifts a sampling position of the down-sampled luminance signal in accordance with a scan to be processed. A video decoding device includes a down-sampler with sampling position shifter 205 configured to down-sample a luminance signal, and a predictor 203 configured to linearly predict a color difference signal from a down-sampled luminance signal. The down-sampler with sampling position shifter 205 shifts a sampling position in the down-sampled luminance signal in accordance with a scan to be processed.
