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.

An information processing apparatus includes: a data processing unit generates contents to be provided to a client, extracts plural blocks as content configuration data from an original content, sets patterns including block rows of the extracted blocks, generates encrypted blocks applying block keys which are different according to respective patterns and respective blocks, selects encrypted blocks from the patterns at random in each content delivery, generates individually-encrypted portions by encrypting part of configuration data of the selected blocks by applying an individual key corresponding to a client as a content delivery destination, and generates encrypted content including encrypted blocks on which encryption processing by the block keys is performed and individually-encrypted portions on which encryption processing by the individual key is performed as the content to be provided to the client.
摘要:
An information processing apparatus including: 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 copy restriction information received from a management server, comparing the copy restriction information with apparatus setting information set in a memory of the information processing apparatus, determining whether or not the copy processing is permitted in accordance with the comparison result, and copying recorded data of the first medium to the second medium under the condition it is determined that the copy processing is permitted.
摘要:
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.

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: a data processing unit that generates data for copy of data recorded on an information recording medium, wherein the information recording medium has a configuration in which data encrypted by applying an individual unit key in unit of a unit, which is segment data corresponding to an individual title, is recorded, and the data processing unit acquires title information recorded in copy processing information acquired from the information recording medium or a management server, acquires a unit key corresponding to the acquired title information, and executes decryption processing in unit of the unit by the acquired unit key to generate the data for copy.
摘要:
An information processing device including a data processing section which executes control of a copying process where recording data on a first medium is recorded onto a second medium, and a data conversion section which executes data conversion in the copying process, where the data processing section acquires position information of a packet, which corresponds to an angle change point, based on conversion data generated by the data conversion section and executes an updating process on a reproduction control information file where angle change point position information of data before conversion which is recorded in the reproduction control information file included in copy target data is changed to angle change point position information of data after conversion.
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.
