Generating apparatus information streams, generating process information streams, encoding apparatus, encoding method, recording medium and program for them.

An apparatus stream generation information generating a train of information including (i) order management information mmco memory for managing a buffer (2004) storing a decoded as a reference image picture, and (ii ) coded pictures, said apparatus comprising: a generating unit (1004) operable to generate the coded pictures by coding pictures, an adding unit operational commands to add the MMCO to a predetermined coded picture, characterized by: an evaluation unit (1002) operable to assess whether a first coded picture or not skipped at the time of trick-play and is added with MMCO; and an operating repeat unit (1003) for generating an information supplementary reinforcement redialing of decoded reference picture DRPMR SEI, and to repeat MMCO entering data of MMCO to the DRPMR SEI, when said evaluation unit evaluates the first coded picture to be skipped at the time of trick-play and is added with MMCO; wherein said generation unit is operable to generate the information stream, adding the DRPMR SEI to a second coded picture that follows, in decoding order, the first coded picture and should not skip at the time of trick-play .
