VIDEO ENCODING DEVICE, VIDEO DECODING DEVICE, VIDEO ENCODING METHOD, VIDEO DECODING METHOD, AND PROGRAM

摘要

A video encoding device includes: a transformer for transforming an image block; an entropy encoder for entropy-encoding transformed data of the image block transformed by the transformer; a PCM encoder for PCM-encoding an image block; a multiplexed data selector for selecting output data of the entropy encoder or output data of the PCM encoder, for each block of an externally set block size; and a multiplexer for embedding a PCM header into a bitstream, in a block of the externally set block size, wherein the number of successive PCM-encoded blocks is embedded into the PCM header, and PCM data for the number of successive PCM-encoded blocks is multiplexed into the bitstream.

1. A video encoding device comprising:
a transform unit which transforms an image block; an entropy encoding unit which entropy-encodes transformed data of the image block transformed by the transform unit; a PCM encoding encoding unit which PCM (Pulse Code Modulation)-encodes an image block; a multiplexed data selection unit which selects output data of the entropy encoding unit or output data of the PCM encoding unit, for each block of an externally set block size; a multiplexing unit which embeds a PCM header into a bitstream, in a block of the externally set block size; an embedding unit which embeds the number of successive PCM-encoded blocks, into the PCM header; and a PCM data multiplexing unit which multiplexes PCM data for the number of successive PCM-encoded blocks, into the bitstream.
