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 having a high resolution video signal recorded thereon and a system for reproducing signal, which are compatible with a conventional system for reproducing an ordinary resolution video.

SOLUTION: Streams obtained by dividing a high resolution signal into a main signal and a sub signal by a video separator and MPEG-coding are divided into frames each having ≥1 GOP. A first interleave block 54 and a second interleave block 55 which are obtained in this way are alternately recorded on an optical disk 1. A high resolution reproduction apparatus obtains a high resolution video by reproducing both first and second interleave blocks. At the same time, a non-high image quality reproduction apparatus reproduces only the first or second interleave block, so that an ordinary resolution video is obtained.
