    摘要: A contents using device (or a terminal device) 300 is composed of: a license processing unit 305 which judges, on the basis of a usage rule of a license, whether or not the content is available; a content reproduction unit 304 which uses the content judged by the terminal device 300 to be available; a restriction unit (or a content reproduction unit 304) which restricts the license corresponding to the contents from being used by another source by reason that the license is currently in use, for a time period between a start and a normal end of the content usage by the content reproduction unit 304; an event detection unit 307 which detects a predetermined event that occurs between the start and the normal end of the content usage and that forcefully aborts the content usage; a restriction-relaxation necessity judgment unit (or a recovery/penalty judgment unit) 309 which judges whether or not the predetermined event is against an intention of a user; and a restriction relaxation unit (or a license recovery unit) 306 which relaxes the restriction on the content usage when the recovery/penalty judgment unit 309 judges that the predetermined event is against the intention of the user.

    摘要: The invention relates to power saving in portable terminals (100) with recording media (200). Conventionally, there is the problem that a battery (104) in the portable terminal (100) may become exhausted and as a result the original function of the terminal cannot be performed. To solve this problem, when the remaining battery capacity is low, the invention controls power supply (108) to the recording media (200) and clock supply (110) to a CPU (202) in the recording media (200) so as to reduce power supplied to the recording media (200)

    摘要: A content playback apparatus reduces load concentration on a specific server apparatus that manages content keys of encrypted content, while protecting copyrights of the content. The content apparatus makes playback of content recorded in a recording medium sold possible after the specific server breaks down. A key acquisition control unit (204) reads a playback control information table (211) from a recording medium (102) via a reading unit (201). The key acquisition unit (204) acquires a rights key via a key acquisition intermediation unit (223) from an apparatus specified by an acquisition-destination type and a request-destination type that are stored in the playback control information table (211) and that corresponding to the content to be played. The key acquisition unit (204) generates a content key using the acquired rights key and, when required, a medium key recorded in a medium. A decryption unit (203) decrypts encrypted content using the content key.
