The present invention registers a content so that its composition can be easily recognized, and promotes the reduction of a load in playing processing on the registered content, and improves convenience of users. Also, it evaluates the value of production of a content more properly. An information processing apparatus includes: a generator for generating meta information including content composition information representing a composition of a content to be registered, and mashed-up-or-not information representing whether a content to be registered is a unitary content or a mashed-up content in which a plurality of contents are combined; and a register for registering the generated meta information as content information.
