Abstract:
1. A stream generation apparatus which generates a stream that includes (i) information obtained by coding a command for managing a buffer that holds a decoded picture as a reference picture, and (ii) a coded picture, said apparatus comprising: a judging unit operable to judge whether or not a first coded picture is a coded picture corresponding to a picture that is to be skipped at a time of trick-play, the first coded picture being added with a first information obtained by coding the command; a coding unit operable to code same contents as the command shown by the first information, as a second information, when said judging unit judges that the first coded picture is the coded picture corresponding to the picture that is to be skipped at the time of trick-play; and a generation unit operable to generate the stream, by adding the second information to a second coded picture that follows the first coded picture in decoding order and that corresponds to a picture which is not to be skipped at the time of the trick-play.
