Patent ID: 8315501

Claim:
A reproduction apparatus, comprising: a reproduction section which reproduces video data from a record medium, the video data being managed in a unit of a clip composed of a plurality of frames which are chronologically successive, each frame being one of I (Intra-coded) picture data, B (Bi-directional) picture data and P (predictive-coded picture data); a decode section which (a) compares a storage state of a current frame pattern for a frame buffer, which stores a plurality of frames for the video data currently reproduced by the reproduction section, with a target reproduction frame buffer pattern which designates an output frame pattern of a plurality of frames necessary to decode a next frame, the target reproduction frame buffer pattern including the target frame and adjacent frames earlier and later than the target frame, (b) removes only one unnecessary frame in a current state of the frame buffer based on the comparison and (c) newly decodes and stores one new frame in an area which the one unnecessary frame is removed; and a control section which controls the decode section to pre-decode a frame of a second clip and to store the pre-decoded frame in the frame buffer based on the target reproduction frame which is a frame which is currently being output in the first clip and a frame which is output at beginning of a second clip adjacent to the first clip in a reproduction order.
