摘要： To provide a moving picture stream generation apparatus and the like that generates a moving picture stream that can be played back in trick-play such as variable-speed playback and reverse playback even in a coding format such as the MPEG-4 AVC in which flexible prediction structures are allowed.A moving picture stream generation apparatus includes: a trick-play information generation unit TricPlay for generating supplemental information on a random access unit basis, the supplemental information being referred to at the time of playback of each random access unit and each random access unit including one or more pictures; and a variable length coding unit VLC for generating a stream including the generated supplemental information and the one or more pictures by adding the supplemental information to each corresponding random access unit. At the top of each random access unit, an intra coded picture that can be decoded without depending on any picture is placed, and the supplemental information includes information for specifying pictures to be decoded at the time when pictures included in each random access unit are played back in trick-play.

摘要： A moving image encoding method of the present invention is a moving image encoding method for encoding a moving image while switching between variable-length encoding schemes. In this method, a continuous unit to be continuously reproduced is determined (S5201); a stream is generated by encoding the moving image without switching between variable-length encoding schemes in the continuous unit (S5202); and management information is generated that includes a first flag information indicating that a variable-length encoding scheme is fixed in the continuous unit (S5204, and S5205).

摘要： A stream generation apparatus generates a stream including coded pictures and a command for managing a buffer which holds a decoded picture, the command being added to one of the coded pictures as a reference picture. A judging unit judges whether or not the coded picture to which the command is added is skipped at the time of trick-play, and an adding unit adds, in the case where the coded picture is judged to be skipped, repetition information indicating the same contents as the command to another coded picture that follows, in decoding order, the coded picture judged to be skipped and that is not skipped at the time of the trick-play. A generating unit generates the stream including the coded pictures, the command and the repetition information.
