Patent number: 8688587Abstract: Disclosed is a content recording apparatus having recording devices A and B and first and second encrypting units that are provided for the respective recording devices. When receiving stream data representing content from an input unit, a rate changing unit operates so as to input streams of data in parallel to the respective encrypting units. The first encrypting unit encrypts the stream data with an encryption key generated from the IDs of the recording device A and of a recording medium a. The second encrypting unit encrypts the stream data with an encryption key generated from the IDs of the recording device B and of a recording medium b. Each of the recording devices A and B records the content encrypted by a corresponding one of the first and second encrypting units.Type: GrantFiled: October 13, 2005Date of Patent: April 1, 2014Assignee: Panasonic CorporationInventors: Miki Shimizu, Hiromichi Shimada

Publication number: 20110182156Abstract: Optical disc recording processing of recording data to be recorded on an optical disc having a plurality of recording layers at a recording velocity depending on the radial position includes use pattern selection processing of selecting a use pattern in which given recordable regions included in a data zone of the optical disc are used for recording of the data to be recorded in given use order, among a plurality of use patterns different in the number of recording layers used, so that the total recording time is shortened, based on given conditions including at least the capacity of the data to be recorded, the recording velocities of use regions in the use pattern, and the number of interlayer shifts in the use pattern. The data to be recorded is recorded according to the use pattern selected in the use pattern selection processing.Type: ApplicationFiled: April 6, 2011Publication date: July 28, 2011Applicant: PANASONIC CORPORATIONInventors: KEISUKE SASAKI, HIROMICHI SHIMADA, HIROYUKI YABUNO

Patent number: 6992959Abstract: In a DVD player, when data information in a DVD disk is played back, it is judged whether the data information is protected by a copyright or not on the basis of disk control information. Further, it is judged whether the DVD disk is writable or not, based on whether the DVD disk is provided with a wobble or not. Thus, if the data information is protected by the copyright and the DVD disk is writable, a playback of the DVD disk is prevented so that an illegal use of the DVD disk, which infringes the copyright, is effectively prevented.Type: GrantFiled: November 2, 1999Date of Patent: January 31, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshihiro Tosaki, Tsutomu Kai, Shinji Inoue, Hiromichi Shimada

Remote control unit for operating server, and server system including server and remote control unit
Publication number: 20040237115Abstract: A remote control unit can operate a server capable of transmitting contents data, and accept a recording medium. The remote control unit includes a controller for generating a control signal to control the server and the remote control unit, an operation section for switching an operating mode of the remote control unit, a transmitter/receiver operable to transmit the control signal generated by the controller to the server, and to receive the contents data from the server, and a recorder/reproducer. The recorder/reproducer is operable to accept the recording medium, record the contents data received by the transmitter/receiver into the recording medium, reproduce data from the recording medium, and output the data to the transmitter/receiver. According to the control signal generated by the controller based on the operating mode, the recorder/reproducer is operable to switch a function of the remote control unit between a drive belonging to the server and a drive independent from the server.Type: ApplicationFiled: May 17, 2004Publication date: November 25, 2004Inventors: Koichi Horiuchi, Hiromichi Shimada, Toyohiko Matsuda, Kuninaga Azuma -
Patent number: 6791937Abstract: A DVD-R 1 has a main information area 2 where data information is recorded in a track having a wobble, and first and second control data areas 3,15 each of which is disposed in an inner space closer to the disk center than the main information area 2. The information structure and physical structure of the first control area 3 are different from those of the second control area 15. In the second control area 15, predetermined physical format information and disk production information, for example, the last address of when data is written in the DVD-R 1, the maximum transfer rate or the like, are recorded. Thus, when the DVD-R 1 is reproduced by a DVD player etc., the physical format information and disk production information etc. recorded in the second control data area 15 are read.Type: GrantFiled: April 29, 2002Date of Patent: September 14, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshihiro Tosaki, Masaru Odagiri, Hiromichi Shimada, Shinichi Tanaka
