ABSTRACT:
Picture data are reproduced by fast forward (F.F.) or fast backward (F.B.) reproduction from moving picture data including picture frames belonging to the first picture frame group obtained by compressing picture data in accordance with intra-frame method and picture frames belonging to the second picture frame group obtained by compressing picture data in accordance with inter-frame prediction method and further coded at a high efficiency by a high efficiency compression system. During the real time reproduction, an average interval between two adjacent picture frames belonging to the first frame group is obtained. Further, during F.F. or F.B. reproduction, a search start position of a first picture frame to be next reproduced after a second picture frame now being reproduced is set based on the obtained average interval, the first and second picture frames belonging to the first picture frame group, and the first picture frame is started to be searched from the set search start position.
