OPTICAL DISK FOR HIGH RESOLUTION AND THREE-DIMENSIONAL VIDEO RECORDING, OPTICAL DISK REPRODUCTION APPARATUS, AND OPTICAL DISK RECORDING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an optical disk with signals of three-dimensional video and high resolution image recorded thereon and a system for reproducing data on the disk, which are compatible with a conventional system for reproducing ordinary resolution image.

SOLUTION: A first image signal and a second image signal are divided into groups of frames of one GOP or more. As for interleave blocks laterally alternately recorded on an optical disk 1, a three-dimensional/high resolution image-compatible reproducing apparatus reproduces both first and second interleave blocks, thus providing a three-dimensional image or a high resolution image and a three-dimensional/high resolution image-non-compatible reproducing apparatus reproduces only one of the first and second interleave blocks by jumping tracks, thus providing an ordinary resolution image.
