Abstract

Peculiar identification information to identify a recording medium itself is recorded onto the recording medium on which contents information as a target of a reproduction deadline management is recorded. At least the identification information recorded on the recording medium as mentioned above is read by a terminal apparatus and transmitted to a server apparatus. In the server apparatus, a reproduction possible deadline of the contents information recorded on the recording medium is managed on the basis of reproduction possible deadline information indicative of the reproduction possible deadline regarding the contents information recorded on the recording medium on the basis of at least the identification information. Thus, when the reproduction deadline of the contents recorded on the recording medium is managed, the operation for allowing the server apparatus side to set registration information such as personal information or the like of the user as in the conventional system is unnecessary.
