Claim:
An information processing apparatus, comprising: a local storage in which a virtual file system is created, the virtual file system supporting an information recording medium on which encrypted content, with respect to which an encryption process has been performed, is recorded, the encrypted content being managed for each of content management units serving as content use management units, and on which content management units used by the encrypted content are set; and a playback unit, implemented by a hardware processor, configured to read and play back the encrypted content managed by the content management units used by the encrypted content by using the virtual file system created in the local storage, configured to receive a data distribution file set for linking other information with the encrypted content of the information recording medium, the encrypted content being distributed from an information distribution server, and configured to update the virtual file system using the received data distribution file set, wherein the playback unit supplies, to a name mapping mechanism of the virtual file system, name mapping information specifying a file set associated with a fixed title, the file set to be exchanged with a file set provided in advance in the local storage, the file set being replaced with a file set downloaded into the local storage and used, so that the fixed title is used by a plurality of file sets by using the virtual file system, and each of a Blue-ray Disc Java object file, a Blue-ray Disc program file, a playlist file, a clip information file, and an audio-visual stream file in the data distribution file set are individually mapped to corresponding virtual file system names associated with the fixed title, when the data distribution file set is to be used.
