Patent number: 8042192Abstract: The present invention relates to an information processing apparatus, an information processing method, a recording medium, and a program for importing and exporting a content with information missing controlled. A CPU extracts a sound track contained in the content in step S301, and converts a format of the extracted sound track into a format compatible with a memory stick in step S302. The CPU generates a predetermined file from data contained in the content and excluding the sound track in step S304. In step S306, the CPU attaches reference information of the sound track to the file. In step S307, the CPU controls the writing of the sound track in the converted format and the file to the memory stick. The present invention is applied to clients of a DRM system.Type: GrantFiled: November 12, 2008Date of Patent: October 18, 2011Assignee: Sony CorporationInventors: Yoji Kawamoto, Ryuji Ishiguro, Yuichi Ezura, Motohiko Nagano

Patent number: 7861313Abstract: The present invention relates to an information managing apparatus and method, a recording medium, and a program in which unauthorized use of content can be prevented. A ripping module 91 of a client 1 retrieves the content recorded on a CD 81. In the client 1, a content ID for identifying the content and a unique ID unique to the client 1 are generated, and these IDs are added to the content retrieved by the ripping module 91. A usage right containing the usage conditions of the content, etc., is generated and saved. The usage right includes information indicating that an apparatus (client) having the same ID to the unique ID added to the content is only allowed to play back the content. The present invention is applicable to an information processing apparatus such as a personal computer.Type: GrantFiled: October 26, 2007Date of Patent: December 28, 2010Assignee: Sony CorporationInventors: Yoji Kawamoto, Ryuji Ishiguro, Yuichi Ezura, Motohiko Nagano

Patent number: 7730345Abstract: Even if contents data distributed over a network are once destroyed, the contents data are restored, as the copyright protection is maintained. A PC memorizes backup of distributed music contents on a hard disc, at the same time as it transmits the using log information of the music contents stored in the hard disc to an EMD server. If the music contents in the hard disc are destroyed, the PC acquires the using log information from the EMD server to reproduce the backup data memorized in the hard disc depending on the using log information.Type: GrantFiled: March 20, 2007Date of Patent: June 1, 2010Assignee: Sony CorporationInventors: Ryuji Ishiguro, Itaru Kawakami, Mitsuru Tanabe, Yuichi Ezura, Ichiro Sato, Munetake Ebihara

Patent number: 7516497Abstract: An information processing apparatus is provided including a memory configured to store content data and corresponding content management information. The content management information defines a rule set relative to reproduction of the content data. The content data and management data are embodied in a first format. A processor is configured to convert the first format of the content management information into a second format, different from the first format. A transmitter is provided to transmit the second format of the content management information to another information processing apparatus.Type: GrantFiled: November 15, 2006Date of Patent: April 7, 2009Assignee: Sony CorporationInventors: Itaru Kawakami, Ryuji Ishiguro, Mitsuru Tanabe, Yuichi Ezura

Patent number: 7437768Abstract: The CPU 11 of the personal computer 1 controls the CPU 32 of the adaptor 26 made of a semiconductor ID to compute a hash value of a content-managing music data base recorded in the HDD 21 and store it into the nonvolatile memory 34. When playing back a content recorded in the HDD 21, the CPU 11 computes the hash value of the music data base recorded in the HDD 21, compares it with hash values stored cumulatively in the nonvolatile memory 34, and controls the playback of the content from the HDD 21 based on the result of the comparison.Type: GrantFiled: October 19, 2005Date of Patent: October 14, 2008Assignee: Sony CorporationInventors: Itaru Kawakami, Ryuji Ishiguro, Mitsuru Tanabe, Yuichi Ezura

Patent number: 7266691Abstract: After a reproduction program is installed on a PC, a key for CD ripping is furnished e.g., from an FD. With the key for CD ripping, the music contents in a CD can be copied to a PC, however, it is not possible to download music contents from an EMD server for copying on a PD. For storing the music contents distributed from the EMD server on the PD, the reproduction program first acquired a key for EMD different from the key for ripping over the network. By so doing, the contents data distributed over the network may be improved in safety.Type: GrantFiled: October 25, 2000Date of Patent: September 4, 2007Assignee: Sony CorporationInventors: Ryuji Ishiguro, Itaru Kawakami, Mitsuru Tanabe, Yuichi Ezura, Ichiro Sato, Munetake Ebihara

Patent number: 7249106Abstract: A contents database 114 memorizes the discriminating information for discriminating contents and the temporal information as to the time of content duplication associated with the discriminating information. A recording program 113 acquires the discriminating information of contents to be duplicated and duplicates the contents in association with the acquired discriminating information and with the temporal information memorized in the contents database 114. This substantially prohibits duplication in large quantities without significantly impairing the interests of a user.Type: GrantFiled: December 24, 1999Date of Patent: July 24, 2007Assignee: Sony CorporationInventors: Mitsuru Tanabe, Itaru Kawakami, Ryuji Ishiguro, Yuichi Ezura
