摘要： A content playback apparatus prevents related content recorded on separate media that make up a virtual package from being played separately, thereby restricting playback of the content to only when the virtual package is assembled as intended by the creator, and protecting copyright of the content. A key obtaining unit obtains a second key, with use of key management information recorded on a recording medium on which related content relating to the encrypted content is also recorded. An information obtaining unit obtains the encrypted content and key generation information that relates to generation of the first key, from a source other than the recording medium. A key generation unit generates the first key with use of the second key and the obtained key generation information. A decryption unit decrypts the encrypted content with use of the first key.

摘要： A rental system includes a terminal apparatus, a BD player, and a server apparatus. At renting BD storing pieces of content, the terminal apparatus writes rental information including content ID identifying each piece of content, viewing status, and content key, to the user's memory card. The player plays back content when viewing status is "viewing-permitted" or "additionally-viewed", and when viewing status is "not-viewed", changes to "additionally-viewed", and plays it back. At returning BD, the terminal apparatus calculates a content rental fee when "additionally-viewed" is in the memory card, and charges the fee to the user. The terminal apparatus reads use-history information about playback of content from the memory card, internally stores it as use information, and regularly transmits the use information to the server apparatus managed by the content provider. The server apparatus calculates a content fee using the stored use information, and charges the fee to the rental agent.

摘要： A storage-medium rental system includes a portable storage medium to be rented to the user, a portable semiconductor memory owned by the user, a rental-shop apparatus owned by the rental agent, and a playback apparatus owned by the user. The storage medium prestores encrypted content generated by encrypting digital work using a content encryption key. The semiconductor memory has an area f or securely storing a content decryption key. The rental-shop apparatus stores a content decryption key for decrypting the encrypted content. The rental-shop apparatus writes the content decryption key to the semiconductor memory. The playback apparatus securely reads the content decryption key from the semiconductor memory, reads the encrypted content from the storage medium, decrypts the encrypted content using the content decryption key, and plays back the decrypted content.
