  • Patent number: 8510421
    Abstract: A system including a server holding content and a terminal using the content, whereby the terminal is registered in the server if a communication time between the terminal and the server is less than or equal to a reference value. A measuring unit of the server measures a communication time from transmitting measuring information to the terminal until receiving response information from the terminal, and repeats the transmission, the reception, and the measurement until the measured communication time is less than or equal to the reference value. An elapsed-time measuring unit measures an elapsed time from when the measuring unit first begins measuring the communication time, and a transmission unit transmits, to the terminal, status notification information showing a processing status depending on the elapsed time. A response unit of the terminal receives measuring information from the server and transmits response information to the server when the measuring information is received.

  • Patent number: 8220064
    Abstract: A content management system which can prevent a content from being copied exceeding the limited number of copies for the content. The content management system includes a first content management device and a second content management device. The first content management device stores period information that indicates an available period during which a first external device is permitted to use a copied content which has been copied from the content, and outputs the period information to the second content management device when the content is moved. Upon receiving the period information from the first content management device, the second content management device judges whether the available period of the copied content has expired, using the received period information, and if it is judges that the available period has not expired, it inhibits the content from being copied to the second external device.
