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： Processing load on an executing device for conducting playback is high during the playback of contents since the executing device performs verification of the contents validity in parallel with the contents playback, and therefore the executing device has to be equipped with a highly efficient processor. The present invention reduces the processing load involved in the verification by using, for the verification, only a predetermined number of encrypted units selected randomly from multiple encrypted units constituting encrypted contents recorded on the DVD. In addition, the present invention is capable of improving the accuracy of detecting unauthorized contents to some extent by randomly selecting a predetermined number of encrypted units every time the verification is performed.
摘要翻译：由于执行装置与内容重放并行地执行内容有效性的验证，所以在内容的重放期间，用于进行再现的执行装置上的处理负载很高，因此执行装置必须配备高效率的处理器。本发明通过仅使用构成在DVD上记录的加密内容的多个加密单元随机选择的预定数量的加密单元来验证验证。此外，本发明能够通过每次执行验证时随机选择预定数量的加密单元，来在一定程度上提高检测未授权内容的准确性。

摘要： The recorder/reproducer, when moving a first content data, writes a second content data, which is obtained by re-coding the first content data recorded in a first recording medium, into a second recording medium instead of the first content data, writes one or more first partial information extracted from the first content data into the second recording medium, and makes the first content data irreproducible, using one or more first invalidated partial information having one-to-one correspondence with the extracted one or more first partial information. When restoring the first content data, it makes the irreproducible first content data reproducible, using the one or more first partial information recorded in the second recording medium.

摘要： A content management system formed from a playback apparatus that requests and plays content, and a content management apparatus that manages duplication and deletion of content. The playback apparatus notifies group information of the playback apparatus to the content management apparatus, acquires information from the content management apparatus showing whether requests are permitted, and duplicates/deletes content. By judging whether the playback apparatus belongs to a group, and notifying whether a duplication request is permitted or rejected, based on in-group and out-group remaining numbers that show the remaining number of duplications permitted of apparatuses in-group and out-group, respectively, the content management apparatus relaxes restrictions on in-group content duplication as compared with out-group content duplication, and thus improves convenience for users in a home network, while protecting the rights of copyright holders, with respect to content duplication and usage.
