Abstract
A recording medium stores contents and contents keys to be used for encrypting the contents, in a plurality of storage formats. The storage formats include a storage format (a first format) for delivered contents acquired through a network, and a storage format (a second format) for local contents acquired by a method other than the delivery. The intrinsic storage formats of the contents to be stored in the recording medium are determined according to the kinds of the contents. The recording medium stores not only the contents and the contents keys but also original storage format information (an import flag) () which is information indicating the intrinsic storage formats of the contents. With reference to the original storage format information, a reproduction device selects a reproduction method in accordance with the intrinsic storage formats of the contents.
