Abstract

A method and an apparatus for providing information of a device to other devices through the home network are provided. The method includes: generating relative location information indicating that a first device is present in a vicinity of a second device if a remote control signal for the second device is received; and providing the relative location information as location information of the first device to at least one other device belonging to the home network. Accordingly, the user can acquire location information of devices belonging to the home network. Therefore, it is possible to easily identify the correspondence of devices visually recognized by the user to the device list obtained as a result of the search.

Claims

1. A method of providing device information through a home network, the method comprising:

generating relative location information indicating that a first device is present in a vicinity of a second device if a remote control signal for the second device is received; and

providing the relative location information as location information of the first device to at least one other device belonging to the home network.

2. The method of claim 1, further comprising:

receiving absolute location information from the second device; and

providing the absolute location information as location information of the first device to the at least one other device belonging to the home network.

3. The method of claim 1, wherein the remote control signal comprises an Infrared Data Association (IrDA) signal.

4. The method of claim 1, wherein the home network is based on a Universal Plug and Play (UPnP) protocol, and

wherein in the providing the relative location information, the relative location information is inserted in a service description document and an <

alive>

message or a <

M-Search>

response message including a Uniform Resource Locator (URL) of the service description document is transmitted.

5. The method of claim 2,

wherein the home network is based on a Universal Plug and Play (UPnP) protocol, and

wherein in the receiving the absolute location information, an <

alive>

message including a Uniform Resource Locator (URL) of a service description document having the absolute location information inserted therein is received.

6. The method of claim 2,

wherein the home network is based on a Universal Plug and Play (UPnP) protocol, and

wherein in the providing the absolute location information, the absolute location information is inserted in a service description document and an <

alive>

message or a <

M-Search>

response message including a Uniform Resource Locator (URL) of the service description document is transmitted.

7. A computer-readable medium having embodied thereon a computer program for executing the method comprising:

generating relative location information indicating that a first device is present in a vicinity of a second device if a remote control signal for the second device is received; and

providing the relative location information as location information of the first device to at least one other device belonging to the home network.

8. A home network device comprising:

a location information generating unit which generates relative location information indicating that a first device is present in a vicinity of a second device if a remote control signal for the second device is received through a home network comprising a plurality of devices; and

a location information provider which provides the relative location information as location information of the first device to at least one other device belonging to the home network.

9. The device of claim 8, wherein the location information provider receives absolute location information input by a user from the second device and provides the absolute location information as location information of the first device to the at least one other device belonging to the home network.

10. The device of claim 8, wherein the remote control signal comprises an Infrared Data Association (IrDA) signal.

11. The device of claim 8, wherein the home network is based on a Universal Plug and Play (UPnP) protocol, and wherein the location information provider inserts the relative location information in a service description document and transmits an <

alive>

message or a <

M-Search>

response message including a Uniform Resource Locator (URL) of the service description document.

12. The device of claim 9, wherein the home network is based on a Universal Plug and Play (UPnP) protocol, and wherein the location information provider is provided with the absolute location information by receiving an <

alive>

message including a Uniform Resource Locator (URL) of a service description document having the absolute location information inserted therein.

13. The device of claim 9, wherein the home network is based on a Universal Plug and Play (UPNP) protocol, and wherein the location information provider is provided with the absolute location information by inserting the absolute location information in a service description document and transmitting an <

alive>

message or a <

M-Search>

response message including a Uniform Resource Locator (URL) of the service description document.

14. The device of claim 12, wherein the location information provider comprises:

a determining unit which determines whether the <

alive>

message originated from a device of the plurality of devices which pre-provided the relative location information;

a message generating unit which generates a response message for responding to an <

M-Search>

command or the <

alive>

message by including the relative location information in the response message; and

a transmitter which transmits the response message through the home network.
