Abstract: A CD on which only music information specified by the CD-DA is recorded, or a CD on which both music information specified by the CD-DA and music information to be recorded on a CD-ROM are recorded is mounted upon an information processing terminal. When the CD on which only music information specified by the CD-DA is recorded is mounted, the information processing terminal acquires, from a directory server, an ISRC number that identifies the music information recorded on the CD, and distribution server location information that identifies a content distribution server. The information processing terminal acquires content that is the music information compressed according to the MP3 and encrypted, from the content distribution server identified by the acquired distribution server location information, and the decryption key. The information processing terminal then decrypts the acquired content using the acquired decryption key and reproduces music.

Abstract: To provide a content playback device that can use content appropriately by avoiding output of content not permitted to be used according to contract information. A playback control unit 102 extracts a content name from playback control information in a playback path information table 210, and inquires of a rights management unit 108 whether content identified by the extracted content name is playable or not. If the content is judged as being unplayable, the playback control unit 102 extracts an alternative playback number from the playback control information, and extracts a content name from playback control information whose playback number matches the alternative playback number. The playback control unit 102 then instructs a decryption unit 103 and a playback unit 107 to decrypt and play back encrypted content identified by the extracted content name.

Abstract: 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.
