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

摘要

PROBLEM TO BE SOLVED: To provide an optical disk having a high resolution video signal and a system for reproducing thereof, which are compatible with a conventional system for reproducing an ordinary resolution video.

SOLUTION: A high resolution video signal is divided into a main signal and a sub signal by video 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 1. A high resolution reproduction apparatus reproduced both the first and second interleave blocks, so that a high resolution video is obtained. A non-high resolution reproduction apparatus reproduces only the first or second interleave block, so that an ordinary resolution video is obtained.
