OPTICAL DISK FOR HIGH RESOLUTION AND STEREOSCOPIC VIDEO RECORDING, OPTICAL DISK REPRODUCING DEVICE, OPTICAL DISK RECORDER

摘要

PROBLEM TO BE SOLVED: To provide compatibility for an optical disk recorded with stereoscopic video and high-definition video signals and a system for reproducing the signals with a conventional system for reproducing ordinary video.

SOLUTION: A first video signal and a second video signal are respectively divided into frame groups each having one GOP (Group Of Picture) or more, and recorded left and right on an optical disk 1 alternately to form an interleave block. A reproducing device supporting stereoscopic/high definition reproduces both of first and second interleave blocks to obtain stereoscopic video or high-definition video. A reproducing device not supporting stereoscopic/high definition track jumps and reproduces either the first or second interleave block to obtain ordinary video.
