Patent number: 7948356Abstract: A mobile terminal is capable of reducing unnecessary consumption of electric power. The mobile terminal includes a terminal status detecting unit which detects a first terminal status and a second terminal status, the first terminal status being a status of the mobile terminal before a change in the mobile terminal takes place, and the second terminal status being a status of the mobile terminal after the change in the mobile terminal takes place.Type: GrantFiled: October 11, 2005Date of Patent: May 24, 2011Assignee: Panasonic CorporationInventors: Hiromi Kawamura, Masayuki Imada

Patent number: 7254318Abstract: Disclosed is a recording apparatus for recording a plurality of audio-visual contents stored in a HD to a writable DVD. A drive controller copies at least one of the contents stored in the HD to the DVD. If the available capacity of the DVD left after the copying falls short to copy a remaining content, the remaining content is re-encoded prior to being recorded in the DVD. The bit rate to be allocated to the remaining content upon re-encoding is calculated from the available capacity of the DVD and the reproduction time of the remaining content to be re-encoded.Type: GrantFiled: November 27, 2002Date of Patent: August 7, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masayuki Imada, Ryuichi Hori, Masahiro Horie, Masahiro Kawasaki, Toru Suetomo

Patent number: 7031240Abstract: A disc drive device optimally controls a speed for reading RTR-format data, such as video and audio, recorded on a DVD-format disc, thereby enabling real-time playback without interruption. In the disc drive device, information added to each sector is used for determining whether data is RTR-format data. When an error occurs at high-speed reading of RTR-format data and therefore the reading speed is changed to a low speed, the reading speed is so controlled as to be kept at the low speed for reading the following RTR-format data. Thus, for RTR-format data, overhead due to repetitive acceleration and deceleration processes can be avoided, and reading can be carried out without interfering with real-time playback. For normal data, reading can be carried out in a manner similar to that in the background art.Type: GrantFiled: April 22, 2004Date of Patent: April 18, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Toru Suetomo, Masahiro Kawasaki, Masayuki Imada, Yoichi Yamamoto

Patent number: 6873584Abstract: A disk reproducing apparatus and a disk reproducing method which permit continuous reproduction of data of the RTR type without interruption and without affecting real time reproduction. A defective block list with defective blocks and alternative blocks registered linked to each other by the types of defective blocks has been acquired beforehand from a recording medium and when there arises need to read a defective block, its alternative block is read out and forwarded to a reproduction requester. Here, reading control means identifies the type of defective blocks registered on the defective block list and controls the reading according to the identification results.Type: GrantFiled: May 24, 2001Date of Patent: March 29, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masayuki Imada, Yoichi Yamamoto, Masahiro Kawasaki, Yoshinori Imanishi, Toru Suetomo

Publication number: 20030108328Abstract: A recording/reproducing apparatus for deleting or protecting a file. In the apparatus, a detecting unit detects the end of reproduction of a recorded file. When the detecting unit detects the end of the file, an inquiry issuing unit issues an inquiry whether the file is deleted or not to a user. When the user issues an instruction of the deletion, a deleting unit has only to delete the file. Therefore, the user can readily delete a file.Type: ApplicationFiled: December 9, 2002Publication date: June 12, 2003Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Masahiro Kawasaki, Masayuki Imada, Tohru Suetomo

Publication number: 20030023807Abstract: A hard disk drive 102 includes: a disk 11 that stores data in units of sectors; a ROM unit 12 and a RAM unit 13 that store sector information D showing an extent to which a maximum number of transfer-target sectors can be extended; and a control unit 14. The control unit 14 sends the sector information D in response to an inquiry from a controller 101 about the sector information D, extends the maximum number of the transfer-target sectors in accordance with a transfer request for transferring data and with an instruction from the external device on receiving the transfer request while in a state of being instructed by the instruction to ease the restrictions, and transfers data to/from the disk 11.Type: ApplicationFiled: June 11, 2002Publication date: January 30, 2003Inventors: Youichi Yamamoto, Masahiro Kawasaki, Masayuki Imada, Toru Suetomo
