摘要:
An information processing apparatus includes a playback controller and a storage unit. The playback controller reads per-disc or per-title identification information in the form of a media ID recorded onto a disc, and then executes content playback selection processing or determines a playback processing mode according to bit information included in the media ID. The storage unit stores a program that causes the processing of the playback controller to be executed. By thus using the media ID, provided services, such as the content authorized for playback, can be modified.

An information processing device for executing playback processing of a disc recorded content, includes: a data processing unit configured to employ a playlist where content playback order information has been recorded to execute playback of a content; and a local storage unit storing a content; wherein the data processing unit plays a local storage unit stored content instead of a disc recorded content specified with the playlist by content obtaining processing employing mapping information for obtaining a local storage unit stored content as a playback content by employing a disc recorded content information recorded in the playlist. Thus, for example, processing can be performed such that a new commercial content provided by a server is played instead of an old commercial content recorded in a disc.

The present invention relates to a reproducing apparatus, a reproducing method, a program, a program storage medium, a data delivery system, a data structure, and a manufacturing method of a recording medium for easily handling a content file recorded on a disk and an update file recorded on a local storage. Downloaded data can be handled with a file having a path name and a file name on the local storage being different from a file having a path name and a file name on a virtual file system based on a path name specified by an src_file_name field of and a path name specified by a dst_file_name field of a manifest ( ) section. The present invention is applicable to reproducing apparatuses.
摘要:
An information processing system including a medium where a content to be played is stored; and a playing apparatus for playing contents stored in the medium; with the playing apparatus being configured to discriminate the content type of a content selected as an object to be played, to selectively obtain a device certificate correlated with the discriminated content type from a storage unit, and to transmit the selectively obtained device certificate to the medium; with the device certificate being a device certificate for content types in which content type information where the device certificate is available is recorded; and with the medium determining whether or not an encryption key with reading being requested from the playing apparatus is an encryption key for decrypting an encrypted content matching an available content type recorded in the device certificate, and permitting readout of the encryption key only in the case of matching.

The present invention relates to a compound or a pharmacologically acceptable salt thereof having superior glucokinase activating activity, and is a compound represented by general formula (I), or pharmacologically acceptable salt thereof: [wherein, A represents, for example, an oxygen atom or sulfur atom, R1 represents, for example, a C1-C6 alkyl group, a C1-C6 alkoxy group or a C1-C6 halogenated alkyl group, A and R1 together with the carbon atom bonded thereto form a heterocyclic group that may be substituted with 1 to 3 group(s) independently selected from Substituent Group α, R2 represents a phenyl group that may be substituted with 1 to 5 group(s) independently selected from Substituent Group α or a heterocyclic group that may be substituted with 1 to 3 group(s) independently selected from Substituent Group α, R3 represents a hydroxy group or a C1-C6 alkoxy group, and Substituent Group α consists of, for example, a halogen atom, a C1-C6 alkyl group, a C1-C6 alkyl group substituted with 1 or 2 hydroxy group(s), a C1-C6 alkylsulfonyl group, and a group represented by the formula —V—NR5R6 (wherein, V represents a carbonyl group or a sulfonyl group, and R5 and R6 may be the same or different and respectively represent a hydrogen atom or a C1-C6 alkyl group, or R5 and R6 together with the nitrogen atom bonded thereto form a 4- to 6-membered saturated heterocycle that may be substituted with 1 or 2 group(s) independently selected from a C1-C6 alkyl group and a hydroxy group, and the 4- to 6-membered saturated heterocycle may further contain one oxygen atom or nitrogen atom)].
摘要:
An information processing apparatus includes: a reproducing unit that reads, from a disc, a content and a content code file storing a content code that includes at least any one of a program or conversion data applied to a content reproducing process, to execute the content reproducing process; and a signature verification unit that verifies a digital signature set for the content code file. The signature verification unit verifies the signature using different pieces of set signature target data between a signature verification process executed in reproducing the content recorded in a ROM disc and a signature verification process executed in reproducing the content recorded in a non-ROM disc other than the ROM disc. The reproducing unit, when signature verification is successfully executed by the signature verification unit, applies the content code stored in the content code file, for which signature verification is successful, to reproduce the content.
摘要:
An information processing system includes a medium storing contents for reproduction, and a reproducing device to reproduce the contents. The reproducing device obtains a device certificate and transmits the device certificate to the medium. The device certificate includes the reproducing device's type information, and the medium encodes a media ID for identifying the medium according to an encoding algorithm selected according to the reproducing device's type information. The encoded media ID is transmitted to the reproducing device, which decodes the encoded media ID according to a decoding algorithm corresponding to the device type of the reproducing device, and decrypts and reproduces data to which the obtained media ID is applied.

An information processing apparatus includes: a communication unit which performs communication with a management server; and a data processing unit which performs copy processing for recording recorded data of a first medium in a second medium, wherein the data processing unit performs processing for displaying a content list having a data entry compatible with a copy unit included in recorded data of the first medium on a display unit on the basis of the received information from the management server, and the data processing unit displays a data entry in which the data form of each copy unit is identifiable in accordance with selection information included in the received information from the management server.
摘要:
An information processing apparatus includes: a data processing unit which performs copy processing for recording recorded data of a first medium in a second medium, wherein the data processing unit performs processing for referencing selection information received from a management server, selecting a copy unit having a data form defined as copy permitted data in the selection information from the first medium, and copying the copy unit to the second medium.
摘要:
An information processing apparatus includes an application execution unit configured to generate data to be recorded onto a medium that records data or reproduce data from the medium, a file system unit configured to manage data recorded on the medium using a file system, and a file conversion unit configured to perform conversion between a first file format processable by the application execution unit and a second file format defined by the file system. The file conversion unit converts a file of the first file format generated by the application execution unit into a file of the second file format having an allowable size defined by the file system and supplies the converted file to the file system unit in the form of a file to be recorded.
