A design data storage unit stores a plurality of pieces of design data. A judgment unit 203 judges whether a circuit for decrypting an encrypted content received from a content server 10 is realized in a reconfigurable unit 208, and judges whether a piece of the design data for realizing the circuit for decrypting the encrypted content is held. If the desired circuit is not realized in the reconfigurable unit 208 and the desired piece of the design data is not held, the desired piece of the design data is acquired from a design data server 30 via a network. |
