    摘要： A content recording/reproducing system, which records and reproduces a sub-content relating to a main content, includes a distribution device, first and second recording media, a recording device and a reproducing device. The first recording medium that is non-rewritable prestores key data based on which a public key is derivable, and the main content. The distribution device outputs verification information that includes the sub-content and is generated by applying a digital signature to relative information relating to the sub-content based on a secret key corresponding to the public key. The recording device acquires and records the verification information on the second recording medium that is rewritable. The reproducing device acquires the key data from the first recording medium and the verification information from the second recording medium, derives the public key from the key data, verifies the verification information using the public key, and reproduces the sub-content if the verification succeeds.

    摘要： An information presentation system simplifies entry of information relating to a package media of a user, and management of the information. The information presentation system is made up of a playback apparatus, a library information management apparatus, and a terminal apparatus. The playback apparatus reads an identifier identifying a content from a portable recording medium in which the content is recorded, and transmits the read identifier to the library information management apparatus via a network. The library information management apparatus receives the identifier, acquires attribute information showing attributes of the content identified by the identifier, generates library information including the attribute information and the identifier, and stores the library information. Further, upon request by the terminal apparatus, the library information management apparatus generates presentation information based on the library information, and transmits the presentation information. The user accesses the presentation information using the terminal apparatus.

    摘要： An aggregation system for aggregating contents recorded on a plurality of recording mediums and recording them onto another recording medium while protecting the copyrights of the contents is provided. An aggregation system (1) includes an aggregation apparatus (16) and a reproduction apparatus (17). The aggregation apparatus (16) obtains a main content from an optical disc (11), obtains a sub content from a memory card (12), and aggregates the obtained main content and sub content and records them onto a portable medium (13). The reproduction apparatus (17) obtains the main content from the optical disc (11), obtains reproduction control information for controlling reproduction of the main content, and reproduces the main content recorded on the optical disc (11) based on the reproduction control information.
