OPTICAL DISK FOR RECORDING HIGH-RESOLUTION AND THREE-DIMENSIONAL VIDEO, OPTICAL DISK REPRODUCTION DEVICE, AND OPTICAL DISK RECORDING DEVICE |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide compatibility with a conventional system reproducing a normal-resolution video, in an optical disk with high-resolution video signals recorded thereon and a system for reproducing the high-resolution video signals. <P>SOLUTION: A high-resolution video signal is divided into a main signal and an auxiliary signal by video separation means. A first interleave block 54 and a second interleave block 55, in which respective streams subjected to MPEG coding are divided into frame groups of 1GOP or more, are recorded alternately on an optical disk 1. A reproduction device corresponding to high-resolution obtains a high resolution video by reproducing both the first and second interleave blocks. On the other hand, a reproduction device which does not correspond to high-image-quality obtains a normal-resolution video by reproducing only one of the first and second interleave blocks. <P>COPYRIGHT: (C)2013,JPO&INPIT |
