Abstract:
An encoding method and apparatus which include a coded picture that enables special playback to be easily performed while suppressing reduction in coding efficiency are provided. Coding is performed per a certain number of pictures, including pictures for special playback. When coded pictures for special playback using an interframe predictive coding scheme, referencing is limited to coded pictures encoded using an intraframe predictive coding scheme or coded pictures encoded using the interframe predictive coding scheme having the same reference limitation.
