Abstract:
When the terminal device attempts to use a special content, which has an attribute including information distinguishing the special content from regular contents and which is stored in the recording medium device, the recording medium device refers to the revocation information indicating terminal devices restricted from using the special content. When the recording medium device determines the terminal device as a terminal device to be restricted from using the special content based on the terminal identifying information of the terminal device, the usage information output unit of the recording medium device does not transmit the necessary information for using the special content to the terminal device.
