A DVD reproduction apparatus includes a video decoder capable of outputting smooth video data during forward or backward high-speed reproduction. The video decoder is intermittently supplied with data in VOBU (Video Object Unit) units. According to control by a controller, the decoder outputs the decoded I pictures or P pictures from a memory having a capacity of three or more pictures. In a case of forward reproduction, the pictures are outputted according to the time axis, and in a case of backward reproduction, the pictures are outputted in the opposite direction of the decoding order. Moreover, the decoder counts a VOBU passing time through a demultiplexer provided at a preceding stage and outputs respective pictures at averaged intervals. That is, because three pictures are outputted for each VOBU, pictures are outputted at an interval of the averaged VOBU passing time multiplied by ⅓.
