Abstract

A control device which controls the power of a plurality of apparatuses in a home network, and a method thereof are provided. The control device includes an input unit which receives a power off command, and a control unit which concurrently turns off apparatuses which are currently turned on among the plurality of apparatuses in response to the power off command received by the input unit. Therefore, it is possible for a user to concurrently turn off currently running apparatuses so user convenience can increase.

First claim

What is claimed is:

1. A device comprising:
a communication unit; and
a controller configured to:
in response to receiving power state information of each of a plurality of apparatuses in a home network and receiving a single power off command from an external device, identify at least one apparatus which is currently turned on among the plurality of apparatuses based on the received power state information, and
control the communication unit to transmit a command to turn off the identified at least one apparatus.

2. The device of claim 1 , wherein the power state information of each of the plurality of apparatuses comprises identification information and power control information associated with each of the plurality of apparatuses.

3. The device of claim 1 , wherein the controller is further configured to confirm that at least one apparatus is currently turned on, if at least one response is received from the at least one apparatus of the plurality of apparatuses within a predetermined period of time after queries are transmitted to the plurality of apparatuses.

4. The device of claim 1 , wherein the controller is further configured to, based on not receiving the power state information from any one of the plurality of apparatuses, determine that the one of the plurality of apparatuses is currently turned off.

5. The device of claim 1 , wherein single power control information is used to control power of the plurality of apparatuses, and
wherein the controller is further configured to control the communication unit to transmit the power control information to the identified at least one apparatus which is currently turned on, among the plurality of apparatuses, to control the identified at least one apparatus which are currently turned on to be turned off.

6. A method of controlling a plurality of apparatuses in a home network, the method comprising:
in response to receiving, by a device, power state information of each of a plurality of apparatuses in a home network and receiving a single power off command from an external device, identifying at least one apparatus which is currently turned on among the plurality of apparatuses based on the received power state information, and
transmitting, from the device, a command to turn off the identified at least one apparatus.

7. The method of claim 6 , wherein the power state information of each of the plurality of apparatuses comprises identification information and power control information associated with each of the plurality of apparatuses.

8. The method of claim 7 , wherein the method further comprises transmitting, from the device, power control information to the identified at least one apparatus which is determined to be currently turned on, among the plurality of apparatuses, to control the identified at least one apparatus which are currently turned on to be turned off.

9. The method of claim 6 , wherein the receiving the power state information comprises, if at least one response is received from at least one apparatus of the plurality of apparatuses within a predetermined period of time after queries are transmitted to the plurality of apparatuses, confirming that the at least one apparatus is currently turned on.

10. A non-transitory computer-readable recording medium having recorded thereon a program which causes a device to execute a method of controlling a plurality of apparatuses in a home network, the method comprising:
in response to receiving, by the device, power state information of each of a plurality of apparatuses in a home network and receiving a single power off command from an external device, identifying at least one apparatus which is currently turned on among the plurality of apparatuses based on the received power state information, and
transmitting, from the device, a command to turn off the identified at least one apparatus.

11. The non-transitory computer-readable recording medium of claim 10 , wherein the power state information of each of the plurality of apparatuses comprises identification information and power control information associated with each of the plurality of apparatuses.

12. The non-transitory computer-readable recording medium of claim 10 , wherein the receiving power state information comprises, if at least one response is received from at least one apparatus of the plurality of apparatuses within a predetermined period of time after queries are transmitted to the plurality of apparatuses, confirming that the at least one apparatus is currently turned on.

13. The non-transitory computer-readable recording medium of claim 10 , wherein the method further comprises transmitting, from the device, power control information to the identified at least one apparatus which is determined to be currently turned on, among the plurality of apparatuses, to control the identified at least one apparatus which are currently turned on to be turned off.

14. A system comprising:
a device configured to be communicably connected to a plurality of apparatuses; and
a control device configured to control the plurality of apparatuses via the device,
wherein the device is further configured to, in response to receiving power state information of each of a plurality of apparatuses in a home network and receiving a single power off command from an external device, identify at least one apparatus which is currently turned on among the plurality of apparatuses based on the received power state information and transmit a command to turn off the identified at least one apparatus,
wherein the control device is further configured to receive the power state information from the device, determine which apparatuses among the plurality of apparatuses are currently turned on based on the power state information, and transmit the single power off command to the device in response to a single user input being received.
