Patent number: 9749048Abstract: A connector provided on a projector has an RF chip. A plug connected to the connector has an RF chip at a position opposite to the RF chip of the connector. When a protruding section of the plug is inserted and fit into an aperture section of the connector, the RF chip of the plug and the RF chip of the connector perform wireless communication with each other in a non-contact state. Thus, a connecting tool can be easily attached to/detached from a receiving tool without breaking a terminal due to contact such as in a case where a conventional contact type terminal is used.Type: GrantFiled: September 29, 2015Date of Patent: August 29, 2017Assignee: Sony CorporationInventors: Koichiro Kishima, Ayataka Nishio, Tamotsu Yamagami

Patent number: 8565055Abstract: In step S1, the address generator generates address information composed of a sync signal which is recorded on an optical disc, address data and an error correction code for the address data, pre-encodes and supplies it to a modulator. At the same time, a carrier signal generator generates a carrier signal which is to carry the address information, and supplies it to the modulator. In step S2, the modulator makes MSK modulation of the carrier signal supplied from the carrier signal generator on the basis of the pre-encoded address information supplied from the address generator, and supplies a resultant MSK modulation signal to a wobbling unit. In step S3, the wobbling unit forms, on the optical disc, a spiral groove wobbled adaptively to the MSK modulation signal supplied from the modulator. In this optical disc, a given address can be accessed quickly and accurately.Type: GrantFiled: June 21, 2012Date of Patent: October 22, 2013Assignee: Sony CorporationInventors: Shoei Kobayashi, Nobuyoshi Kobayashi, Tamotsu Yamagami, Shinichiro Iimura

Patent number: 8305856Abstract: To record specific information to a disk-shaped record medium and reproduce the recorded specific information without any influence on the error correction capability. Copy protection information (CPID) having an error correction code appended thereto, shuffled and otherwise treated is sent as a CPID bit block to an EDC rewrite circuit (14). The EDC rewrite circuit (14) rewrites an error detection code appended to user data in each sector in accordance with bit information in the CPID bit block. Thereafter, the data in each sector is scrambled, and an ECC block including a plurality of sectors is modulated with an error correction code and sync signal appended thereto. The modulated signal is recorded in a reserve area of a lead-in area of the disk-shaped record medium. During reproduction, CPID is restored based on the result of error detection of each sector.Type: GrantFiled: September 29, 2006Date of Patent: November 6, 2012Assignees: Sony Corporation, Matsushita Electric Industrial Co., Ltd., Koninklijke Philips Electronics N.V.Inventors: Shoei Kobayashi, Tamotsu Yamagami, Yuji Takagi, Makoto Usui, Paulus Gijsbertus Petrus Weijenbergh, Bart Van Rompaey

Patent number: 7975206Abstract: An ECC block is constituted by RS(248,216,33). Of a data length of 216 bytes (symbols), only 16 bytes are allocated to BCA data and the remaining 200 bytes are used for fixed data having a predetermined value. Using the fixed data of 200 bytes and the BCA data of 16 bytes, parities of 32 bytes (symbols) are calculated. Only the BCA data of 16 bytes and the parities of the former 16 bytes of the 32-byte parities, that is, a total of 32 bytes only, are recorded in a burst cutting area of an optical disc. In decoding, error correction processing is carried out by using the fixed data of 200 bytes. The unrecorded parities of 16 bytes are processed as having been erased. Thus, the error correction capability in a burst cutting area of an optical disc can be improved.Type: GrantFiled: April 18, 2007Date of Patent: July 5, 2011Assignees: Sony Corporation, Panasonic Corporation, Koninklijke Philips Electronics, N.V.Inventors: Shoei Kobayashi, Susumu Senshu, Tamotsu Yamagami, Makoto Usui, Hideshi Ishihara, Mitsurou Moriya, Cornelis Marinus Schep, Jakob Gerrit Nijboer, Aalbert Stek

Patent number: 7913146Abstract: Optical discs are adapted to be used with a light beam having a wavelength of 405 nm for recording or reproducing data. Error correcting blocks for recording BMID including copy protection key information are defined on optical discs (1) dedicated to data reproduction. A data string of BMID to be recorded has 64 bytes. An error correcting block is constituted by 304 columns of error correcting code words (LDC). A BMID data string of 64 bytes is inserted to predetermined 64 error correcting code words (LDC) of a block (304 columns of error correcting code words). The total code length of the predetermined 64 error correcting code words (LDC) is 248 bytes, of which a predetermined byte (symbol) is replaced by a predetermined byte (symbol) of the BMID data string.Type: GrantFiled: January 31, 2006Date of Patent: March 22, 2011Assignee: Sony CorporationInventors: Shoei Kobayashi, Seiji Kobayashi, Tamotsu Yamagami

Patent number: 7861142Abstract: Four ECC blocks are recorded in a burst cutting area of an optical disc. Each ECC block is constituted by a BCA content code of 1 byte, content data length of 1 byte, and content data of 14 bytes. Of the BCA content data, the leading 6 bits are used for application ID and the remaining 2 bits are used for block number. Disc ID is stored in the content data. Since the four ECC blocks exist, the optical disc can be managed individually by four applications at the maximum. Thus it becomes possible to manage the same optical disc by a plurality of applications.Type: GrantFiled: April 24, 2007Date of Patent: December 28, 2010Assignees: Sony Corporation, Panasonic Corporation, Koninklijke Philips Electronics N.V.Inventors: Shoei Kobayashi, Susumu Senshu, Tamotsu Yamagami, Makoto Usui, Hideshi Ishihara, Mitsurou Moriya, Cornelis Marinus Schep, Jakob Gerrit Nijboer, Aalbert Stek

Patent number: 7616552Abstract: An optical disc or other optical recording medium enables reading barcode-shaped-BCA marks in a burst cutting area (BCA) with tracking on while making tampering with the BCA marks difficult. The optical disc 100 has a first area 102 containing tracks at a first track pitch d2, and a second area 101 containing tracks at a second track pitch d1. The barcode-shaped marks 104 are recorded in the second area, and the second track pitch is wider than the first track pitch.Type: GrantFiled: February 10, 2003Date of Patent: November 10, 2009Assignees: Koninklijke Philips Electronics, N.V., Panasonic Corporation, Sony CorporationInventors: Shinya Abe, Shin-ichi Tanaka, Hiroshi Ogawa, Jacobus Petrus Josephus Heemskerk, Tamotsu Yamagami, Cornelis Marinus Schep
