Abstract

The present invention has an objective of realizing compatibility of an optical disk having a high resolution video signal recorded thereon and a system for reproducing the optical disk, with a conventional system for producing a standard resolution video signal. A high resolution video signal is divided by video division means into a main signal and a sub signal, and the main signal and the sub signal are MPEG-encoded. The stream of the main signal and the stream of the sub signal are divided into 1 GOP or more of frames. First interleave blocks 54 each including 1 GOP or more of the stream of the main signal and second interleave blocks 55 each including 1 GOP or more of the stream of the sub signal are recorded on an optical disk 1. A high resolution reproduction apparatus reproduces both the first and second interleave blocks to obtain a high resolution video output. A non-high quality picture reproduction apparatus reproduces only the first or second interleave blocks to obtain a standard resolution video output.

Claims

1. An optical disk reproduction apparatus for reproducing a signal recorded on an optical disk, in which the optical disk has, recorded thereon, at least a first video stream for outputting a left eye component of a stereoscopic video signal and a second video stream for outputting a right eye component of the stereoscopic video signal, the first video stream and the second video stream each being a stream for stereoscopic video, the first video stream includes a plurality of first interleave units, the second video stream includes a plurality of second interleave units, the first video stream and the second video stream are alternately recorded on tracks of the optical disk in units of the interleave units, and information to find whether or not a stream for stereoscopic video exists on the optical disk is recorded on the optical disk, the optical disk reproduction apparatus comprising, when the information indicates that a stream for stereoscopic video exists on the optical disk:

a reproduction section for reproducing the first video stream and the second video stream recorded on the optical disk;

a resolving section for resolving the reproduced first video stream into the plurality of first interleave units and the reproduced second video stream into the plurality of second interleave units; and

a decoding section for decoding the plurality of first interleave units to generate a first reproduction signal for outputting the left eye component signal of the stereoscopic video signal and for decoding the plurality of second interleave units to generate a second reproduction signal for outputting the right eye component signal of the stereoscopic video signal.

2. An optical disk reproduction apparatus according to claim 1, further comprising an output section for alternately outputting the first reproduction signal and the second reproduction signal.

3. A method for recording to an optical disk, comprising:

a stream generating step of generating a first video stream including a plurality of first interleave units from the first video signal and generating a second video stream including a plurality of second interleave units from the second video signal;

an outputting step of alternately outputting the plurality of first interleave units included in the first video stream and the plurality of second interleave units included in the second video stream;

a recording step of recording the signal outputted in the outputting step on an optical disk; and

a step of recording information to find whether or not a stream for stereoscopic video exists.

4. A method for recording to an optical disk according to claim 3, further comprising:

a dividing step of dividing a stereoscopic video signal into a first video signal for outputting a left eye component of the stereoscopic video signal and a second video signal for outputting a right eye component of the stereoscopic video signal.
