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.

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)
摘要翻译：本发明涉及具有记录介质（200）的便携式终端（100）中的节能。通常，存在便携式终端（100）中的电池（104）可能耗尽的问题，结果不能执行终端的原始功能。为了解决这个问题，当剩余电池容量低时，本发明将记录介质（200）的电源（108）和时钟供应（110）控制到记录介质（200）中的CPU（202），以便减少提供给记录介质（200）的功率

摘要： An internal data storage unit stores distributed music data. A copyright management table stores a process right to each music data item. The process right includes a playback right and a right to copy the data to an external storage medium. A control unit refers to the stored process right to determine whether an inputted instruction can be executed. If determining that the instruction can be executed, the control unit supplies a control signal to a playback unit or another relevant process unit. A display unit displays the stored process right based on an operation mode set in a mode storage unit. The playback and copy rights to the data are displayed with icons. If an icon indicating a copyright in use is selected, information is displayed about the external medium to which the data was copied. If the inputted instruction cannot be executed, a warning screen is displayed.
摘要翻译：内部数据存储单元存储分布式音乐数据。版权管理表存储每个音乐数据项的处理权。该过程权限包括播放权和将数据复制到外部存储介质的权利。控制单元参考所存储的处理权限，以确定是否可以执行输入的指令。如果确定可以执行指令，则控制单元将控制信号提供给重放单元或另一相关处理单元。显示单元基于在模式存储单元中设置的操作模式显示存储的处理权。数据的播放和复制权利将显示图标。如果选择了指示使用版权的图标，则显示关于复制数据的外部介质的信息。如果输入的指令无法执行，则显示警告画面。
