ABSTRACT:
A recompression apparatus for video data possesses a first transcoder, which is able to generate an output video data by recompressing an input video data encoded by a first encode scheme, a second transcoder, which has a compressibility smaller than the first transcoder and is able to generate an output video data by recompressing an input video data by a second encode scheme, and a controller, which receives a recompression parameter including a reduction rate of a target bit rate of an output video data against an input video data, controls a transcoder to carry out compression encoding if the reduction rate is smaller than a threshold value and controls a transcoder to carry out recompression if the reduction rate is equal to or larger than the reduction value.
