Abstract:
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.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.
Abstract:
PROBLEM TO BE SOLVED: To solve difficulty in searching data recorded on an exchangeable medium such as an optical disc, and to provide the optical disc allowing the data recorded on the optical disc to be searched by a simple operation.SOLUTION: Transmitting/receiving antennas 2 and 3 are provided along an inner periphery of an optical disc 1. An IC module connected to a transmitting/receiving IC having ID information is formed, and the IC is embedded in an optical disc substrate. By attaching a radio transmitting/receiving IC 4 having the ID information to the disc, management of each disc by the ID can be performed. Thus, an IC-module-embedded optical disc excellent in mass productivity is enabled.

PROBLEM TO BE SOLVED: To provide a communication device which can simplify various setting operations in a display device such as a TV which provides information associated with an article (communication device).SOLUTION: An imaging device 1 has an RF-ID 47 which performs a proximity radio communication with an RF-ID reader/writer 46 connected to a TV 45 by an infrared communication path. The imaging device 1 includes: a proximity radio communication antenna 21; a data reception unit 105 which receives an input signal supplied from the reader/writer 46; a nonvolatile second memory 52 which stores a UID unit 75 as identification information for identifying at least the communication device and an operation program 116 executed by the TV 45 by referencing the UID unit 75; and a data transfer unit 108 which transmits the UID unit 75 and the operation program 116 to the reader/writer 46 via the antenna 21 in accordance with the input signal. The transmitted UID unit 75 and the operation program 116 are transferred to the TV 45 via the reader/writer 46.
Abstract:
PROBLEM TO BE SOLVED: To provide an optical disk having a high resolution video signal recorded thereon and a system for reproducing signal, which are compatible with a conventional system for reproducing an ordinary resolution video. SOLUTION: Streams obtained by dividing a high resolution signal into a main signal and a sub signal by a video separator and MPEG-coding are divided into frames each having ≥1 GOP. A first interleave block 54 and a second interleave block 55 which are obtained in this way are alternately recorded on an optical disk 1. A high resolution reproduction apparatus obtains a high resolution video by reproducing both first and second interleave blocks. At the same time, a non-high image quality reproduction apparatus reproduces only the first or second interleave block, so that an ordinary resolution video is obtained. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an optical disk in which a three-dimensional video signal and a high resolution video signal are recorded and a system for reproducing the signals recorded in the optical disk, which are compatible with a conventional system for reproducing an ordinary resolution image. SOLUTION: A first video signal and a second video signal are respectively divided into frame groups of one GOP or more and alternately recorded in right and left interleave blocks on an optical disk 1. A three-dimensional/high resolution compatible reproducing apparatus reproduces both of first and second interleave blocks to obtain a three-dimensional image or a high resolution image. A three-dimensional/high resolution non-compatible reproducing apparatus reproduces only either one of the first and second interleave blocks by jumping tracks to obtain an ordinary resolution image.

Abstract:
PROBLEM TO BE SOLVED: To provide an optical disk having a stereoscopic video signal and a high quality video signal recorded therein, and a system which can reproduce the optical disk, wherein a compatibility with a prior art system for reproducing an ordinary video can be achieved. SOLUTION: For a reproducer compatible with stereoscopic and high-quality video signals, a stereoscopic or high-quality video is obtained by dividing each of first and second video signals into a group of frames more than 1 GOP, and reproducing both of first and second interleave blocks recorded on an optical disk 1 alternately at its right and left sides. For a reproducer not incompatible with stereoscopic and high-quality video signals, an ordinary video is obtained by track jumping and reproducing only one of the first and second interleave blocks.

Abstract:
PROBLEM TO BE SOLVED: To achieve compatibility with a conventional system for reproducing normal images in an optical disk in which three-dimensional images and high quality video signals are recorded and a system for reproducing the images and the video signals from the optical disk. SOLUTION: A stereoscopic/high quality correspondence type reproducing device obtains three-dimensional images or high quality images by reproducing both of first and second interleaved blocks which are obtained by respectively dividing first and second video signals into frame groups of one GOP or more and alternately recording the divided frame groups on the right and left sides of the optical disk 1. In a stereoscopic/high quality non-correspondence type reproducing device, only either one of the first and second interleaved blocks is track-jumped and reproduced to obtain normal images.
