Scheme for realizing communications through external network from contents processing device connected to local network in home environment

A contents processing device, comprising:

• a home network interface for connection to a home network;
• a protocol processing unit for executing protocol processing for communications with a server device through a telephone network;
• a solicitation unit for soliciting a set up of connection to the server device through the telephone network, to a gateway device which is connected with both the home network and the telephone network, by using the home network interface when the contents processing device is in a state not capable of carrying out direct communications through the telephone network;
• an information processing unit for processing contents information obtained by the communications with the server device through the gateway device and the home network interface;
• and
• an extraction unit for extracting an address information of the server device to be communicated with in order to obtain a permission regarding contents information utilization,
• wherein the solicitation unit solicits the set up of connection to the server device according to the address information extracted by the extraction unit, and the protocol processing unit carries out a prescribed procedure for obtaining the permission from the server device through the connection established by the gateway device in response to a solicitation by the solicitation unit.
