Abstract

An electronic device can include: a communication unit; a display unit for display contents; and a controller configured to: display a user interface for querying whether to continuously display the contents or stop a display of the contents on the display unit, when the electronic device enters a high rate time slot determined based on electricity rate information received through the communication unit, receive an input for stopping the display of the contents through the user interface, and output a power ON signal and source information of the contents to a replacement electronic device.

Claims

1. An electronic device comprising:

a communication unit;

a display unit for display contents; and

a controller configured to;

display a user interface for querying whether to continuously display the contents or stop a display of the contents on the display unit, when the electronic device enters a high rate time slot determined based on electricity rate information received through the communication unit,

receive an input for stopping the display of the contents through the user interface, and

output a power ON signal and source information of the contents to a replacement electronic device.

2. The electronic device of claim 1, wherein the controller automatically selects the replacement electronic device based on a predetermined criterion, when the input for stopping the display of the contents is received through the user interface.

3. The electronic device of claim 2, wherein the selected replacement electronic device consumes less power than the electronic device.

4. The electronic device of claim 1, wherein the controller provides a selection list associated with the replacement electronic device, when the input for stopping the display of the contents is received through the user interface.

5. The electronic device of claim 4, wherein the selection list includes at least one of a name of the replacement electronic device, a screen size of the replacement electronic device, a unit electricity rate of the replacement electronic device, a power state of the replacement electronic device, information for whether the replacement electronic device is a portable terminal, remaining charge of the replacement electronic device, and display time to play the contents with the remaining charge.

6. The electronic device of claim 1, wherein the controller turns off the display unit when the input for stopping the display of the contents is received through the user interface.

7. An electronic device comprising:

a communication unit;

a display unit for display contents; and

a controller configured to;

display a user interface for querying whether to continuously display the contents or stop a display of the contents on the display unit, when the electronic device enters a high rate time slot determined based on electricity rate information received through the communication unit,

receive an input for stopping the display of the contents through the user interface, and

output a power ON signal and contents stored in the electronic device in a form of streaming data to a replacement electronic device.

8. The electronic device of claim 7, wherein the contents are streamed in a form of one of original data before the contents are decoded, decoded data, and data trans-coded to conform to device characteristics of the replacement electronic device.

9. The electronic device of claim 7, wherein the controller automatically selects the replacement electronic device based on a predetermined criterion, when the input for stopping the display of the contents is received through the user interface.

10. The electronic device of claim 9, wherein the selected replacement electronic device consumes less power than the electronic device.

11. The electronic device of claim 7, wherein the controller provides a selection list associated with the replacement electronic device, when the input for stopping the display of the contents is received through the user interface.

12. The electronic device of claim 11, wherein the selection list includes at least one of a name of the replacement electronic device, a screen size of the replacement electronic device, a unit electricity rate of the replacement electronic device, a power state of the replacement electronic device, information for whether the replacement electronic device is a portable terminal, remaining charge of the replacement electronic device, and display time to play the contents with the remaining charge.

13. The electronic device of claim 7, wherein the controller turns off the display unit, when the input for stopping the display of the contents is received through the user interface.

14. A method for changing an electronic device for displaying contents, the method comprising:

displaying contents on a display unit;

receiving electricity rate information through a communication unit;

displaying a user interface for querying whether to continuously display the contents or stop a display of the contents on the display unit in a case entering a high rate time slot determined based on the electricity rate information received through the communication unit;

receiving an input for stopping the display of the contents through the user interface; and

outputting a power ON signal and source information of the contents to a replacement electronic device.

15. A method for changing an electronic device for displaying contents, the method comprising:

displaying contents on a display unit;

receiving electricity rate information through a communication unit;

displaying a user interface for querying whether to continuously display the contents or stop a display of the contents on the display unit, in a case entering a high rate time slot determined based on the electricity rate information received through the communication unit;

receiving an input for stopping the display of the contents through the user interface; and

outputting a power ON signal and contents stored in the electronic device in a form of streaming data to a replacement electronic device.
