OPTICAL DISK FOR RECORDING HIGH RESOLUTION IMAGE AND THREE-DIMENSIONAL IMAGE, OPTICAL DISK REPRODUCING APPARATUS, AND OPTICAL DISK RECORDING APPARATUS

摘要

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

SOLUTION: A first video signal and a second video signal are respectively divided into frame groups of one GOP or more and alternately recorded in right and left interleave blocks on an optical disk 1. A three-dimensional/high resolution compatible reproducing apparatus reproduces both of first and second interleave blocks to obtain a three-dimensional image or a high resolution image. A three-dimensional/high resolution non-compatible reproducing apparatus reproduces only either one of the first and second interleave blocks by jumping tracks to obtain an ordinary resolution image.
