Abstract
An optical disc includes a data area for recording a plurality of video segments and index area for recording original type chain information and user-defined type chain information. The original type chain information defines an original type chain including first ones of the video segments by describing a reproduction order of the first video segments. The user-defined type chain information defines a user-defined type chain including second ones of the video segments by describing a reproduction order of the second video segments. The first video segments are positioned in the data area in the reproduction order of the first video segments whereas the second video segments are positioned in the data area independently of the reproduction order of the second video segments.
