Abstract
A recording medium allows random access to be performed in playing back 3D graphics. The recording medium includes a digital stream area where a digital stream including temporally-arranged GOP pairs is recorded, and a map information area where map information is recorded. The map information indicates entry addresses in one to one correspondence with entry times on a time axis of the digital stream, and each entry address shows a beginning of a corresponding GOP pair region in the digital stream area. Each GOP pair includes first-type and second-type GOPs, wherein each first-type GOP is data indicating a plain view picture set to be played back from a corresponding entry time, and each second-type GOP is data to be played back with a corresponding first-type GOP to provide a stereoscopic view. The data indicates a difference between a stereoscopic picture set and the plain view picture set.
