The types of consecutive k pictures are checked. If there is at least one I picture, the last I picture is output (F107) . If there is no I picture, the first P picture is output (F109). If there is neither I picture nor P picture, the last B picture is output (F110). When checking the types of the next plurality of pictures, the types of the first P picture after the output picture and the following pictures included in the consecutive k pictures and the types of the next k pictures following the k consecutive pictures are checked. The same processing is performed thereafter. <IMAGE> |
