<p>A recording/replaying/editing device capable of randomly accessing moving picture data compressed by inter-frame coding even when only a low signal processing capability is available. The recording/replaying/editing device includes: an image data input unit for entering image data compressed by inter-frame prediction; a reference image frame sequence creation determination unit for determining whether or not a reference image frame sequence should be created, based on the number of I frames included in each file in the image data or the intervals at which I frame are inserted; and a reference image frame sequence creation unit for creating, if it is determined by the reference image frame sequence creation determination unit that a reference image frame sequence should be created, a reference image frame sequence consisting of I frames and additional image frames by adding image frames to I frames.</p> |
