摘要

A variable speed reproduction is accomplished without sacrifice of picture quality. A controller 425 creates EP_map() in a clip information file with an address of RAPI extracted by an RAPI information extraction unit 423, PTS of an intra-picture immediately preceded by RAPI, and one of end positions of the intra-picture and second, third, and fourth reference pictured preceded by the intra-picture and stores EP_map() to an output server 426. In other words, the controller 425 copies a value close to a predetermined sector count (the number of sectors that can be read at a time in the encode process) of the end positions of the four reference pictures (1stRef_picture, 2ndRef_picture, 3rdRef_picture, and 4thRef_picture) to N-th Ref_picture copy, decides index_minus1 based on N-th_Ref_picture_copy and records it on a disc.
