Abstract:
PROBLEM TO BE SOLVED: To provide an optical disk in which a high resolution video signal is recorded and a system for reproducing the signal recorded in the optical disk, which are compatible with a conventional system for reproducing an ordinary resolution image. SOLUTION: A first interleave block 54 and a second interleave block 55 which are respectively obtained by dividing a high resolution video signal into a main signal and a sub signal by a video separation means and dividing respective MPEG encoded streams into frame groups of one GOP or more are alternately recorded on the optical disk 1. A high resolution compatible reproducing apparatus reproduces both the first and second interleave blocks to obtain a high resolution image. On the other hand, a high resolution non-compatible reproducing apparatus reproduces only either one of the first and second interleave blocks to obtain a normal resolution image.

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 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 achieve compatibility with a conventional system which reproduces an ordinary resolution video in an optical disk which records a high resolution video signal, and a system which reproduces it. SOLUTION: An optical disk recording apparatus divides a high resolution video signal into a main signal and a sub signal by a video separation means, and alternately records a first interleave block 54 and a second interleave block 55 on the optical disk 1, which are divided blocks of each stream encoded by the MPEG into frame groups of 1 GOP (Group of Pictures) or more. A reproducing apparatus corresponding to high resolution, obtains the high resolution video by reproducing both the first and the second interleave blocks. Meanwhile, a reproducing apparatus non-corresponding to high picture quality, reproduces one of the first or the second interleave block, and obtains the ordinary resolution video.

Abstract:
PROBLEM TO BE SOLVED: To provide an optical disk that records a three-dimensional video and a high quality video signal, and a system for reproducing the optical disk, which are compatible with a conventional system for reproducing an ordinary video. SOLUTION: A first video signal and a second video signal are individually divided into groups of frames each having 1 GOP or more, and resultant groups of frames of the first video signal and resultant groups of frames of the second video signal are recorded on the right and the left alternately on the optical disk 1 to provide interleave blocks. A three-dimensional and high-quality-adaptive reproducer reproduces both of a first and a second interleave block to provide a three-dimensional video or a high quality video. A three-dimensional and high-quality-non-adaptive reproducer reproduces singly one of the first and the second interleave block through track jump to provide the ordinary video.

Abstract:
PROBLEM TO BE SOLVED: To achieve compatibility with a conventional system for reproducing an ordinary video, in an optical disc having three-dimensional video and high-quality video signals recorded therein and a system for reproducing them. SOLUTION: Interleaved blocks are formed by dividing a first video signal and a second video signal into groups of frames of one GOP or more and recording them alternately on the right and left sides on an optical disc 1. In a three-dimension/high-quality-picture compatible reproduction device, a three-dimensional video or a high-quality video is obtained by reproducing both the first and second interleaved blocks. In a three-dimension/high-quality-picture non-compatible reproduction device, the ordinary video is obtained by reproducing only either the first or second interleaved block by jumping tracks.

Abstract:
PROBLEM TO BE SOLVED: To provide a program recommendation server which rejects a program highly preferred in general, and recommends a program suitable for the preference of specific users. SOLUTION: In a program recommendation server 3: a reservation information receiver 230 receives reservation information transmitted by a program viewing terminal; a reservation information DB 235 stores the reservation information with respect to each of the users; a community reservation information statistics section 236 groups the users as a first group, based on the received reservation information, and the reservation information stored for each of the users; a user reservation information statistics section 237 groups the users as a second group including the first group; a recommended program creator 239 generates recommentation information specific to the first group, based on the result of aggregating the reservation information of the users belonging to the first group, and the result of aggregating the reservation information of the users belonging to the second group; a recommendation transmitter 240 transmits the recommentation information to the program viewing terminal, and the program viewing terminal reproduces the program based on the recommentation information.

Abstract:
PROBLEM TO BE SOLVED: To solve the difficulty in searching data recorded on a changeable medium such as an optical disc, and to provide an optical disc allowing data recorded on the optical disc to be searched by a simple operation. SOLUTION: A transmitting/receiving antenna (231) is provided along the inner circumference of an optical disc. An IC module (201) connected to a transmitting/receiving IC (230) having ID information is formed and embedded in an optical disc substrate. Attachment of the radio transmitting/receiving IC having the ID information to the disc enables each disc to be managed by the ID. Thus, the IC-module-embedded optical disc excellent in mass productivity is obtained. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an optical disk having a high resolution video signal and a system for reproducing the optical disk, which are compatible with a conventional system for reproducing an ordinary resolution video. SOLUTION: A high resolution video signal is divided into a main signal and a sub signal by video division means and MPEG-encoded. The main signal and the sub signal are divided into frames each having 1 GOP or more. The resultant first interleave block 54 and second interleave block 55 are recorded alternately on an optical disk 1. A high resolution reproduction apparatus reproduced both the first and second interleave blocks, so that a high resolution video is obtained. A non-high resolution reproduction apparatus reproduces only the first or second interleave block, so that an ordinary resolution video is obtained. COPYRIGHT: (C)2009,JPO&INPIT
