Abstract
Abstract An optical disk having such a data structure that moving image data and audio data are naturally reproduced under one title without stoppage (freeze), etc., of video display at the connections of system streams (VOB) in which the data are interleaved when the data are reproduced by connecting the system streams (VOB) to each other. At least the first audio frame (Af) contains the same audio data in a plurality of branched stream systems (VOB) and at least the last GOP contains the same moving picture in a plurality of system streams (VOB) before connected. <IMAGE>
