Abstract
A smooth reproduced picture is produced at inverse playback, without losing of naturality of display. Picture output candidate frames are decided such that intervals between frame are uniform on a time axis at a normal playback. When the candidate frame exists in a group of pictures (GOP) preceding a GOP which is presently displayed and a number of frames in the GOP is unknown, a frame among one of a last or a second to last I or P coded frame in the GOP, which is nearer to a true picture output frame is decided as a picture output candidate frame.
