Content decryption device

摘要

A decryption unit decrypts encrypted content to generate content. An instruction execution unit outputs a transfer destination address showing a position in a content output unit to an address detection unit. The address detection unit judges whether the transfer destination address matches a pre-stored permitted address, and outputs the generated content only when the transfer destination address and the permitted address match, to the position in the content output unit shown by the transfer destination address. The content output address receives the content and outputs the received content to an external device.
