摘要

An information train generation apparatus that generates an information train that includes (i) OCGM memory management information order for buffer management (2004) that saves a decoded image as a reference image, and (ii ) encoded images, said apparatus comprising: a generating unit (1004) operative to generate the encoded images by image coding, an operative order addition unit for adding the OCGM to a predetermined encoded image, characterized by: a valuation unit (1002) operational to assess whether or not a first encoded image should be skipped at the time of intelligent playback and added with OCGM; and a repeating unit (1003) operative to generate a supplementary reinforcement information for the decoding of the reference image decoded ISR RMIRD, and to repeat OCGM by entering OCGM data in the RMRD ISR, when said valuation unit assesses that the first encoded image must be skipped at the time of intelligent playback and added with OCGM; wherein said generating unit is operative to generate the information stream, adding the RMIRD ISR to a second encoded image that follows, in decoding order, the first encoded image and which should not be skipped at the time of intelligent reproduction .
