摘要： A configuration of performing reliable source analysis of the illegally copied content by using content for which a playback path can be configured is realized. Content is used which has a segment region configured with a plurality of pieces of variation data which can be respectively decrypted by different keys, and for which a playback path can be configured according to selected variation data. In each piece of variation data, a variation data identifier can be analyzed from the decrypted data. The playback device selects variation data according to the playback path information received from the server, and plays content. The server generates management data in which the playback path information notified to the playback device and the playback device identification information are associated with each other, and performs the source tracing of illegal copy, based on the variation data included in the illegally copied content.

摘要： According to the present invention, a data reproduction process and a disc manufacturing process are carried out on the basis of disc type information as disc-recorded data configuration information. A reproduction apparatus executing data reproduction from a disc reads disc type information recorded on the disc, grasps the disc-recorded data configuration on the basis of the disc type information, and executes the data readout and reproduction processes at a transfer rate according to the grasped recorded data configuration. The disc type information includes zone setting information indicating whether the disc is a single-zone disc composed of a single transfer rate zone or a plural-zone disc composed of a plurality of different transfer rate zones. The reproduction apparatus performs data readout and reproduction by the use of algorithms corresponding to the zones.

摘要： To enable conversion of the MPEG-2 TS format data including the variation data into the MP4 format data and, the setting of the reproduction path or the source tracking even in the converted MP4 data. A data processing unit is included which converts MPEG-2 TS format data, which includes segment regions including a plurality of pieces of variation data decryptable with different keys and in which a reproduction path can be set according to the selected variation data, into the MP4 format data. The data processing unit selects the encrypted MP4 variation data from the segment regions of the MPEG-2 TS format and stores the MP4 variation data in an MP4 file while the selected MP4 variation data remains as encrypted data.

摘要： An information processing device and a program processing method, a program storage medium, and a program for allowing a recording method to be selected which records a maximum number of continuous angle-switching units with priority given to the AV stream rate. In step S91 to step S93, the target value of the AV stream rate is obtained, the jump distance is selected, and the corresponding jump time is obtained. In step S94, a minimum angle-switching time is calculated from the jump time and the data read rate and, in step S95, the size of the minimum angle-switching unit is determined according to the minimum angle-switching time and the AV stream rate. In step S96, the number of minimum angle-switching units within the jump distance is calculated and, in step S97, the number of angles that can be recorded is checked. In step S99, a method is selected that continuously records the largest amount of data for a required number of angles. The present invention is applicable to a recording/playback device.

摘要： A configuration capable of performing the using management of each of contents divided at units, strictly and efficiently. CPS units divided from storage contents of an information recording medium are set, and unit keys are made to correspond to the individual CPS units, thereby to encrypt and record the data configuring the individual units. At a reproduction time, the unit keys are created and applied for a data processing. As the creation information of the unit keys, there are applied a copy/reproduce control information (CCI) to be set to correspond to the CPS units, and a contents hash or a hash value based on the CPS unit configuring data. By this configuration, it is possible to realize the tamper protection against the CCI and CPS unit configuring data and the valid contents using configuration.
