Informatiion Processing Apparatus, Information Processing Method and Recording Medium

Abstract

An information processing apparatus, as a recording apparatus, formulates a Clip Information file of a still picture file (TS file), made up by plural still pictures, and a PlayList, composed of plural PlayItems, indicating the replay path of a slide show, and records the information on a DVD along with the TS file. The Clip Information file has an EP_map, as a table indicating the relationship of correspondence between the value of the presentation time stamp PTS of the transport stream TS and the source packet number SPN in the TS the PTS value indicates. The information processing apparatus, as a reproducing apparatus, reads out and reproduces the data address of the TS, represented by the replay start time IN_time and the replay end time OUT_time of the PlayItem.
