摘要： A recording medium (100) for storing content that can be read and written by a host device stores a content key (a key that is used for encrypting content) (805a) encrypted in a first format, and a content key (805b) that is encrypted in a second format for content that is the same as the content related to the content key (805a) encrypted in the first format. The first format is, for example, a format used for distributed content, and the second format is a format used with local content.
摘要翻译：用于存储可由主机设备读取和写入的内容的记录介质（100）存储以第一格式加密的内容密钥（用于加密内容的密钥）（805a）和内容密钥（805b），内容密钥以与第一格式加密的内容密钥（805a）相关的内容的内容的第二格式加密。第一种格式是例如用于分布式内容的格式，第二格式是与本地内容一起使用的格式。

摘要： A recording medium stores contents and contents keys to be used for encrypting the contents, in a plurality of storage formats. The storage formats include a storage format (a first format) for delivered contents acquired through a network, and a storage format (a second format) for local contents acquired by a method other than the delivery. The intrinsic storage formats of the contents to be stored in the recording medium are determined according to the kinds of the contents. The recording medium stores not only the contents and the contents keys but also original storage format information (an import flag) (851) which is information indicating the intrinsic storage formats of the contents. With reference to the original storage format information, a reproduction device selects a reproduction method in accordance with the intrinsic storage formats of the contents.

摘要： While reproducing content stored in a recording medium, a user terminal as a data processing device downloads a related content as different content related to the reproduction target content from a content distribution server via a communication network. Immediately after the reproduction of the reproduction target content is completed, a notification prompting reproduction or purchase of the related content is provided. This permits immediate reproduction of the related content when the user purchases it, which reduces the user's waiting time, thus improving purchase motivation for the related content.

摘要： Area management information is cached in a cache memory by controlling the access size when an information processor accesses the area management information in an information recording medium. When the processing content of the information processor is to retrieve a free area from the area management information, a physical management block size determined from the physical characteristics of the information recording medium is used. When the processing content is to acquire a link destination from the area management information, minimum access unit of the information recording medium is used. Consequently, overhead can be lessened when the area management information is accessed.

摘要： An information recording medium includes a data storage section having a plurality of recording regions for storing data, and a region information storing section operable to store information about each recording region in the data storage section. The region information storing section stores information about a recording region (for example, a recording region has been accessed finally) which is set first as an accessible region when the information recording medium is initialized at the next time among a plurality of recording regions in the data storage section. A data processing apparatus refers to the information about the recording region and changes over a recording region to the recording region specified by the information about the recording region just after initialization of the recording medium.

摘要： The invention presents an encrypted content playback equipment capable of decryption and playback of an encrypted content by using key information when a key medium storing the key information is not inserted, an encrypted content playback method, a program, and a recording medium for storing the program.An encrypted content playback equipment 100 obtains key information 1 for a key medium 120, and stores the key information 1 in a provisional-key storage memory 102 as provisional key 1a, and obtains provisional-key usage limitation information 2 for limiting the use of provisional key 1a from the key medium 120. The encrypted content playback equipment 100 judges whether the provisional key 1a is usable or not based on the provisional-key usage limitation information 2, and if usable, plays back an encrypted content 3 by using the provisional key 1a.

摘要： An information processing device that reads out and records data from and on an information recording medium includes a file system controller. File system control information is constructed in a system memory within the information processing device, and the file system controller unifies and controls a plurality of information recording media which are managed by individual file systems into a single virtual file system. In addition, the file system controller manages a priority order that indicates an information recording medium to be utilized with priority if files having the same name exist. This priority order can be changed in response to a request from an application program. Thus, the processor can unify and manage the plurality of information recording media and, also, enables the application to access all of the files having the same name.

摘要： A content search device calculates the number of valid encrypted contents as comparison objects contained in encrypted content databases and the number of valid decryption keys contained in decryption key databases. The database having the smaller number is decided to be a reference database. By successively reading out entries contained in the reference database, a combination of an encrypted content and a corresponding decryption key is searched.
