To provide a playback device that plays back a content recorded in an optical disc in conjunction with execution of an application supplied by a server. The playback device includes a disc region code detection unit operable to detect a region code from the optical disc; an application region code estimation unit operable to estimate a region code assigned to the application based on an address of the server; a restriction unit operable, if a region code assigned to the playback device, the region code detected from the optical disc, and the estimated region code assigned to the application do not match each other, to restrict the playback of the content in conjunction with the execution of the application.
