Abstract:
PROBLEM TO BE SOLVED: To realize compatibility with a conventional system reproducing a regular video in an optical disk recording a stereoscopic video and a high image quality video signal and a system reproducing the disk.SOLUTION: In a stereoscopic/high image quality correspondence type reproducer, a first video signal and a second video signal are divided into frame groups of 1GOP or more and both first and second interleave blocks which are alternately recorded on the optical disk 1 in right and left are reproduced to obtain the stereoscopic video or a high image quality video. In a reproducer of a stereoscopic/high image quality non-correspondence type, only one of the first and second interleave blocks is reproduced by track jumping so as to obtain the regular image.
Abstract:
PROBLEM TO BE SOLVED: To ensure compatibility between 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. COPYRIGHT: (C)2011,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide a moving picture decoding method capable of reducing the amount of encoding to efficiently perform encoding and decoding. SOLUTION: The method for decoding moving pictures, includes the steps of: holding step for acquiring a second quantization matrix and a matrix ID from a code train to hold them; step for extracting a matrix ID, which accompanies picture encoded data and specifies a quantization matrix used when the current picture is encoded, from the code train; and quantization matrix specifying step for specifying a quantization matrix corresponding to the extracted matrix ID. A picture is composed of a luminance component and two color difference components. In the quantization matrix specifying step, when a quantization matrix for a color difference component does not exist in a quantization matrix specified by the matrix ID, a quantization matrix for another color difference component is specified as a quantization matrix used for color difference component.

PROBLEM TO BE SOLVED: To provide an optical disk in which stereoscopic videos and high-quality video signals are recorded and to provide a system for reproducing the optical disk, the optical disk and the system being made compatible with a conventional system which reproduces an ordinary video.SOLUTION: A reproducing device which is used for reproducing stereoscopic videos and high-quality videos obtains a stereoscopic video or a high-quality video by reproducing both first and second interleaved blocks on the optical disk 1 in which a first video signal and a second video signal are divided into frame groups of one GOP (Group of Pictures) or more and recorded alternately on right and left sides, and a reproducing device which is not used for reproducing the stereoscopic videos and the high-quality videos obtains the ordinary video by reproducing only the first or second interleaved blocks by jumping tracks.

PROBLEM TO BE SOLVED: To attain compatibility for a conventional system for reproducing normal images in an optical disk, in which three-dimensional images and high-quality video signals are recorded, with a system for reproducing the optical disk.SOLUTION: A three-dimensional/high-quality correspondence type reproducing apparatus reproduces both of first and second interleave blocks obtained, by respectively dividing a first video signal and a second video signal into frame groups of 1 GOP and more, and alternately recording respective frame groups to the right and the left sides of an optical disk 1 to obtain a three-dimensional image or a high quality image; a three-dimensional/high-quality non-correspondence type reproducing apparatus reproduces only either the first or second interleave blocks by track jump to obtain a normal image; and the three-dimensional/high-quality correspondence type reproducing apparatus outputs an image signal for a right eye, an image signal for a left eye and a sound signal.
Abstract:
PROBLEM TO BE SOLVED: To provide an optical disk with signals of stereoscopic video and high resolution image recorded thereon and a system for reproducing data on the optical disk, which are compatible with a conventional system for reproducing an ordinary resolution image. SOLUTION: A first image signal and a second image signal are divided into groups of frames of one GOP or more. As for interleave blocks laterally alternately recorded on an optical disk 1, a stereoscopic/high resolution image-compatible reproducing apparatus reproduces both first and second interleave blocks, thereby providing a stereoscopic image or a high resolution image and a stereoscopic/high resolution image-non-compatible reproducing apparatus reproduces only one of the first and second interleave blocks by jumping tracks, thus providing an ordinary resolution image.
