Abstract
A video transcoder includes: a decoding unit which decodes coded video data in which each of blocks in a frame included in the coded video data has been coded for each first unit of coding by switching a frame coding mode and a field coding mode; a coding mode determination unit which determines a coding mode to be applied among the frame coding mode and the field coding mode, based on a first statistical value regarding the frame coded blocks and a second statistical value regarding the field coded blocks for each second unit of coding larger than the first unit of coding; and a re-coding unit which re-codes a block which belongs to a first frame and is coded with reference to a second frame, in the coding mode which is determined to be applied.
