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 high resolution video signal is recorded and a system for reproducing the signal recorded in the optical disk, which are compatible with a conventional system for reproducing an ordinary resolution image.

SOLUTION: A first interleave block 54 and a second interleave block 55 which are respectively obtained by dividing a high resolution video signal into a main signal and a sub signal by a video separation means and dividing respective MPEG encoded streams into frame groups of one GOP or more are alternately recorded on the optical disk 1. A high resolution compatible reproducing apparatus reproduces both the first and second interleave blocks to obtain a high resolution image. On the other hand, a high resolution non-compatible reproducing apparatus reproduces only either one of the first and second interleave blocks to obtain a normal resolution image.
