Abstract

The present invention has an objective of providing an optical disk having a high resolution picture and a system for reproducing data on the optical disk, which are compatible with a conventional system for reproducing an ordinary resolution picture. A high resolution signal is divided into a main signal and a sub signal by picture division means and MPEG-encoded. The main signal and the sub signal are divided into frames each having 1 GOP or more. The resultant first interleave block 54 and second interleave block 55 are recorded alternately on an optical disk. A high resolution reproduction apparatus reproduced both the first and second interleave blocks, so that a high resolution picture is obtained. A non-high resolution reproduction apparatus reproduces only the first or second interleave block, so that an ordinary resolution picture.

Claims

1. An optical disk on which at least a first video stream corresponding to a first signal source and a second video stream corresponding to a second signal source are recorded,

the first video stream is digital data for outputting a component for one of the eyes (a right-eye or a left-eye) of a three-dimensional video (3D) or digital data for outputting a non-three-dimensional video (2D), the second video stream is digital data for outputting a component for the other of the eyes (a left-eye or a right-eye) of the three-dimensional video (3D), the first video stream includes a plurality of first interleave units, the second video stream includes a plurality of second interleave units, each of the plurality of first interleave units includes a plurality of frames, each of the plurality of second interleave units includes a plurality of frames,

wherein, in at least a set of the first interleave unit and the second interleave unit, which are adjacent to each other, among the plurality of first interleave units and the plurality of second interleave units, which are alternately recorded on the optical disk, at least one frame of the plurality of frames included in the first interleave unit has the same time information as at least one frame of the plurality of frames included in the second interleave unit,

the optical disk further having recorded thereon:

information configured such that the reproduction of the second video stream is limited.
