Data structure, recording medium, reproducing device, reproducing method, and program

摘要

Disclosed are a data structure, a recording medium, a reproducing device, a reproducing method, and a program capable of providing a 3D video format suitable for 3D displaying of a caption and a menu button. Left-eye and right-eye caption data used for 3D displaying of a caption are recorded on a disc (501) on a per epoch basis. The left-eye and right-eye caption data reproduced simultaneously have the same epoch structures. That is, the numbers of display sets constituting the epochs of the left-eye and right-eye caption data reproduced simultaneously are equal to each other. The invention is applicable to, for example, a 3D disc.
