Patent ID: 8249991

Claim:
A contents reproduction deadline management system comprising a terminal apparatus and a server apparatus, wherein said terminal apparatus includes a terminal apparatus network interface configured to communicate with said server apparatus through a network, a reading unit configured to read information from a recording medium on which one or more contents information and unique identification information to identify the recording medium have been recorded, wherein the contents information recorded on the recording medium is encrypted, and a reproduction control unit configured to cause said terminal network apparatus interface to transmit at least said identification information read by said reading unit to said server apparatus each time the reading unit reads the content information and unique identification information from the recording medium, and control a reproducing operation of the contents information recorded on said recording medium on the basis of reproducing operation control information received from said server apparatus and corresponding to said transmitted identification information, and said server apparatus includes a server apparatus network interface configured to communicate with said terminal apparatus through said network, a memory configured to store reproduction expiration information showing a reproduction expiration of said contents information recorded on said recording medium on the basis of at least said identification information is stored, wherein the reproduction expiration stored in the memory is based on the time of first receipt of the identification information from the terminal apparatus, a processor configured to discriminate whether the reproduction expiration of the contents information recorded on said recording medium has passed on the basis of said identification information which is received by said server apparatus network interface and said reproduction expiration information stored in said memory, and a communication controller configured to control said server apparatus network interface in such a manner that if it is determined by a discrimination result of said processor that said reproduction expiration is not come yet, reproducing operation control information to enable reproduction of said contents information is transmitted by said server apparatus network interface, wherein the control information enabling reproduction includes key information to decrypt the encrypted content and, if it is determined that said reproduction expiration has passed, the reproducing operation control information to inhibit reproduction of said contents information on said terminal apparatus side is transmitted and the transmission of said key information to said terminal apparatus is inhibited.
