Abstract

This video encoding device is provided with: a transformer that transforms image blocks; an entropy encoder that entropy encodes the transformed data from the image blocks transformed by the transformer; a PCM encoder that PCM encodes the image blocks; a multiplexing data selector that selects output data from either the entropy encoder or the PCM encoder for each block of an externally set block size; and a multiplexer that embeds PCM headers into a bitstream using blocks of the externally set block size. A count of consecutive PCM encoded blocks is embedded into each PCM header and an amount of PCM data corresponding to the number of consecutive PCM encoded blocks is then multiplexed onto the bitstream.
