Abstract

A method and apparatus for reducing power consumption in an electronic device are provided. The method includes receiving media content from a server, establishing a control state based on the media content, controlling power of at least one of a communication connection device and a display according to the control state of the received media content, determining whether a reception of the media content is completed, determining whether the electronic device performs functions for playing and controlling a digital media, transitioning a Wireless Local Area Network (WLAN), when it has been determined that a reception of the media content and that the functions are not performed by the electronic device, to a power save mode, and disconnecting the WLAN, when it has been determined that receiving the media content is completed and that the functions are performed by the electronic device, wherein the electronic device comprises the communication connection device.

Claims

1. A method comprising:

selecting, at a first electronic device, at least one content from one or more contents stored in a second electronic device communicating with the first electronic device via a network;

receiving, at the first electronic device, at least one portion of the at least one content from the second electronic device in a non-power saving mode of the network; and

transitioning the network from the non-power saving mode to a power saving mode based at least in part on a determination that the receiving of the at least one portion is completed,

wherein the determination is based at least partly on whether the second electronic device is transmitting the at least one content to the first electronic device.

2. The method of claim 1, wherein the selecting comprises:

displaying information corresponding to the one or more contents via a display operatively coupled to the first electronic device; and

determining the at least one content based on a user input in relation with the information corresponding to the at least one content.

3. The method of claim 1, wherein the receiving comprises:

presenting the at least one content in a slide show via a display operatively coupled to the first electronic device while the network is in the non-power saving mode.

4. The method of claim 1, wherein the transitioning comprises:

disconnecting a communication connection between the first electronic device and the second electronic device.

5. The method of claim 1, wherein the transitioning comprises:

terminating power supplied to the network.

6. The method of claim 1, wherein the transitioning comprises:

notifying a user of the first electronic device.

7. The method of claim 1, wherein the network comprises a Wireless Local Area Network (WLAN).

8. The method of claim 1, further comprising:

determining an operation state of a display operatively coupled to the first electronic device based at least in part on a reproduction mode of the at least one content.

9. The method of claim 8, wherein the determining comprises:

turning on the display if the reproduction mode is a play mode;

turning off the display if the reproduction mode is a stop mode; and

dimming the display if the reproduction mode is a pause mode.

10. The method of claim 8, wherein the determining is further based on a determination that a specified time has elapsed.

11. A method comprising:

transmitting, at a second electronic device, at least one content selected from one or more contents stored in the second electronic device via a network coupled to one or more first electronic devices; and

terminating a network connection of the second electronic device based at least in part on a determination that the transmitting of the at least one content is completed and that there is no request for the one or more contents from the one or more first electronic devices for at least a specified period time.

12. The method of claim 11, wherein the terminating comprises:

notifying a user of the second electronic device of the disconnection.

13. The method of claim 11, wherein the terminating comprises:

turning off a display operatively coupled to the second electronic device.

14. An apparatus comprising:

a display to display at least one content; and

a controller operatively coupled to the display, the controller configured to;

select at least one content from one or more contents stored in an electronic device communicating with the apparatus via a network,

receive at least one portion of the at least one content from the electronic device in a non-power saving mode of the network, and

transition the network from the non-power saving mode to a power saving mode based at least in part on a determination that the receiving of the at least one portion is completed,

wherein the determination is based at least partly on whether the electronic device is transmitting the at least one content to the apparatus.

15. The apparatus of claim 14, wherein the controller is further configured to control to disconnect a communication connection between the apparatus and the electronic device.

16. The apparatus of claim 14, wherein the controller is further configured to control to terminate power supplied to the network.

17. The apparatus of claim 14, wherein the controller is further configured to control to notify a user of the apparatus.

18. The apparatus of claim 14, wherein the network comprises a Wireless Local Area Network (WLAN).

19. The apparatus of claim 14, wherein the controller is further configured to determine an operation state of the display based at least in part on a reproduction mode of the at least one content.

20. The apparatus of claim 19, wherein the controller is further configured to control to turn on the display if the reproduction mode is a play mode, to turn off the display if the reproduction mode is a stop mode, and to dim the display if the reproduction mode is a pause mode.
