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

摘要

PROBLEM TO BE SOLVED: To provide compatibility between a conventional stereoscopic high- picture quality optical disk and an ordinary image by respectively dividing a basic video signal and an interpolated video signal into frame groups, mutually interleaving them and recording them on an optical disk. SOLUTION: A P-MPEG signal and an L-MPEG signal are interleaved by an interleave circuit 4 so as to alternately arrange an R frame group collecting the frame group of R frames in the R-MPEG signal more than 1 GOP and an L frame group collecting the frame group of frames in the L-MPEG signal more than 1 GOP. The interleave block of such a recording unit is recorded for ten and several rotations more than one rotation of the disk. Then, address information is outputted and progressive/stereoscopic image arrangement information is outputted and recorded on the optical disk by a recording circuit 9. This progressive/stereoscopic image arrangement information contains an identifier showing whether a progressive or stereoscopic image exists on the optical disk or not.
