Abstract:
A video data editing apparatus for use with an optical disc, the optical disc having recorded thereon at least one file of video data split into a plurality of segments, each segment being recorded in a consecutive area on the optical disc, wherein the optical disc is for use with a reproduction apparatus including a read unit, a track buffer, a decoder, and an optical pickup, and the at least one file of video data is accessible by the reproduction apparatus, at least one of the segments are to be read by the read unit via the optical pickup, the video data is to be decoded by the decoder, at least one of the segments are to be inputted into the track buffer, and video data is to be outputted from the track buffer to the decoder, said video editing apparatus comprising:detection means for detecting a first segment, from the plurality of segments, where a length of the consecutive area in which the first segment is recorded is below a predetermined length, the predetermined length being a length below which the first segment would cause an underflow in the track buffer; andlinking means for linking the detected first segment with at least part of a second segment, and moving at least one of the first segment and a linked part of the second segment to a different area of the optical disc so as to make a total continuous length of the first segment and the linked part of the second segment at least equal to the predetermined length, wherein the second segment includes video data that is reproduced either immediately before or immediately after reproduction of video data in the first segment.
