Abstract: In an information recording medium storing many pieces of content, a configuration that allows use management on segmented content basis is provided. A plurality of content management units corresponding to title, index and other information are set by partitioning stored content in an information recording medium. Different unit keys that are encryption keys are allocated to different content management units. At least the content real data included in each content management unit is encrypted by use of the unit key and the encrypted data is stored. In content reproduction, units are identified and decryption is executed by use of a unit key corresponding to each unit for reproduction. In an information recording medium storing many pieces of content for example, each of segmented pieces of content may be managed.

Abstract: Provided are a reproduction device and a reproduction method, which are enabled to easily handle a contents file recorded in a disk and an update fi le recorded in a local storage. Further provided are a program and a program storage medium, a data distribution system, a data structure, and a method f or manufacturing a recording medium. On the basis of both a path name designate d with an src_file_name field of a Manifest () section and a path name designated with a dst_file_name field, the downloaded data can be so handled that the files are different between the path name and file name in the loca l storage and the path name and file name in a virtual file system.

Abstract: 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.
