摘要

An apparatus stream generation information generating a train of information for trick-play, according to MPEG-4 AVC that includes (i) order control operation management OCGM memory for managing a buffer (2004) that stores a decoded picture as a reference 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 or not a first coded picture to which MMCO is added is a reference B picture which can be referred to when another coded picture is decoded; and a repeating unit (1003) operable to generate an information supplementary reinforcement redialing of decoded reference picture DRPMR SEI when said judgment unit (1002) assesses that the first coded picture is the reference B picture and is added with MMCO; wherein said generation unit is operable to generate the information stream by adding the DRPMR SEI to a second coded I picture or a second coded, so that said second image follows the first coded picture in decoding order P picture.
