Abstract:
1. A moving picture decoding apparatus for receiving stream data which includes slice pictures and for decoding the slice pictures to reproduce a moving picture, wherein the slice pictures include, as attribute information, a delimiter indicating a picture boundary, and frame number control information indicating whether an increment in frame_num is limited to 0 or 1, the apparatus comprising: a first decision unit which decides whether the delimiter exists, and which decides that a position of the delimiter is the picture boundary when it is decided that the delimiter exists; a second decision unit which decides whether an increment in frame_num is 1 or more than 1, when the first decision unit decides that no delimiter exists, and which decides that a boundary between a current slice picture and a preceding slice picture is the picture boundary, when deciding that the increment in frame_num is 1; and a controller which discards the current slice picture when the first decision unit decides that no delimiter exists, and the second decision unit decides that the increment in frame_num is more than 1.
