摘要： [Object] To generate content in which it is possible to analyze a source of illegally copied content or the like, and make normal reproduction possible without a pause in reproduction in a reproduction device.
[Solution] Content including an individual segment region formed of a plurality of variation data in which identification information different from each other is embedded and each of which can be decrypted by a different key, and a common segment region is used. The variation data is formed of a 6144-byte aligned unit. A reproduction device calculates a reproduction path by applying a device key, and selects an aligned unit corresponding to the reproduction path from an aligned unit configuring variation data in an individual segment region, and then, executes decryption and reproduction processing.

摘要： An apparatus and method configured to identify the type of a content to be copied and perform a copying process in a sequence according to the result of identification is provided. In an information processing apparatus configured to perform the copying process for copying recorded data in an information recording medium to other media or the like, the type of the data recorded in the recording medium of a copy source is identified. More specifically, whether the type of the content to be copied is either a reproduction-pass-specific content which sets a reproduction pass corresponding to the information processing apparatus and causes the information processing apparatus to execute the reproduction according to the reproduction pass, or a content-code-applied content which verifies the reproduction sequence to be executed in the reproducing apparatus and verifies whether the reproduction process is executed according to the correct reproduction sequence is discriminated, and an optimal sequence is applied on the basis of the result of discrimination, whereby the copying process is executed. In this configuration, a reliable copying process on the basis of the optimal process according to various data types is realized.

摘要： A configuration that can execute a process according to usage rules information inheriting usage rules information delivered by a broadcasting station is realized in using recorded content of an information recording medium. A mapping process is executed to convert set values of usage rules information according to a first standard, such as CI+ (CI Plus), received from the broadcasting station into usage rules information defined by a second standard, such as AACS, different from the first standard to record the usage rules information in the information recording medium. An apparatus that reproduces or copies the recorded content uses the content according to the usage rules information defined by AACS inheriting the usage rules information defined by CI+ (CI Plus) recorded in the information recording medium.

摘要： A structure that can perform an efficient process to update a revocation list in a memory card is realized. This structure includes a data processing unit that controls updating of the revocation list to be stored into a data storage unit, and the data processing unit acquires a revocation list URL from a server that performs data recording on the data storage unit, and acquires the revocation list from a revocation list providing server by using the acquired revocation list URL. The acquired revocation list is further recorded into the data storage unit. In the recording process, a data writing process command that does not include the revocation list is input from a server, the acquired revocation list is inserted into the command, a process based on the command is performed, and the revocation list is recorded.

摘要： A configuration is achieved in which content copying between media and content downloading are performed effectively and under strict management. In content copying between media, the identification information (medium ID) of a copying destination medium is obtained using an API for providing a predefined processing, then the obtained medium ID is transmitted to a server to obtain copying permission information from the server, and then content copying is performed under the management of the server. This configuration allows a copying destination medium to be managed, which can eliminate the unauthorized use of the content. Also, the configuration in which content downloading from the server is performed according to, for example, a Java® program allows a ROM disc on which the content is recorded to store the program and to be provided to a user.

摘要： A configuration is provided that allows secure data management to be performed on subsequently acquired data associated with content management units. When subsequently acquired data, such as information subsequently generated or downloaded by a user in association with content stored on an information recording medium, is recorded to a hard disk or the like, subsequently-acquired-data search information and access control information are set. This configuration allows a subsequently-acquired-data file to be searched for and be obtained based on the subsequently-acquired-data search information and allows access control for each subsequently-acquired-data file to be performed based on the access control information. The search information and the access control information are also set in shared directories, such as a studio shared directory.
