Abstract

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.

Claims

1. A content transmission device coupled to an in-home network, and comprising:

a device information manager unit that registers and manages the device information received from a content-receiving device and a relay device;

a content provider unit that provides the contents to the content-receiving device; and

a remote access setting management unit that performs settings to send the contents to the content-receiving device coupled to the content transmission device by way of an out-of-home network based on the device information that is registered and managed in the device information manager unit,

wherein, the remote access setting management unit;

sets a first coupling information to couple the in-home network and the out-of-home network by a secure communication path, to a relay device containing a remote access server function that relays the in-home network and the out-of-home network communications;

sets a second coupling information to couple by the secure communication path to the content-receiving device containing a remote access client function that acquires the contents and data from the content transmission device coupled to the out-of-home network; and

the content provider unit provides the content by way of the secure communication path when providing the contents to the content-receiving device coupled from the out-of-home network.

2. The content transmission device according to claim 1,

wherein the remote access setting management unit:

manages a third coupling information to couple the in-home network and the out-of-home network by the secure communication path,

sets the first or the second coupling information based on the device information managed by the device information management method in the relay device or the content-receiving device, when the device information for the content-receiving device or the relay device managed by the device information manager unit is adaptable to the third coupling information; and

when not adaptable, the first or the second coupling information is not set in the relay device or the content-receiving device.

3. The content transmission device according to claim 1,

wherein the remote access setting management unit:

manages information for the external server coupled to an out-of-home network; and

decides whether or not the out-of-home network can be coupled by way of the in-home network based on information acquired from the external server.

5. The content transmission device according to claim 1,

wherein the device information that the device information manager unit records and manages, includes information on devices including the remote access server function and devices including the remote access client function.

4. The content transmission device according to claim

wherein the remote access setting management unit manages information for the DDNS server required for coupling to the in-home network from the out-of-home network.
