Devices used in mobile environments are making increasing demands for access to in-home content while commuting or traveling away from home. A content-receiving device that accesses an in-home content transmission device from outside the home: determines a method for establishing secure communication with a router in advance inside the home; executes a first authentication with the content transmission device and registration processing needed during access from outside the home; and registers information relating to the content-receiving device and out-of-home access information with the content transmission device. When utilizing the content-receiving device outside of the home to access the in-home content transmission device, the content transmission device sends content to the content-receiving device only when the content-receiving device is registered with the content transmission device, and only when second authentication is successful using the out-of-home access information therebetween. |
