A system allows a user to integrally manage content regardless whether the content is owned or not owned by the user. In a reproduction terminal, one piece of sort-out information is generated from one play list. Sort-out information is obtained by classifying the metadata of content registered with a play list into three types of metadata, search metadata, display metadata and processing metadata. The sort-out information generated in the reproduction terminal is transmitted to a reproduction terminal via a sort-out information server. In the reproduction terminal, a same play list as a play list of the reproduction terminal is created on the basis of the provided sort-out information. In the created play list, each piece of content registered with the play list is managed by making a distinction between the content owned by the user and the content not owned by the user.
