Abstract

A multimedia device for effectively managing power consumption thereof based on a handle that is used when moving the multimedia device is provided. The multimedia device includes a display, a handle attached to the multimedia device, a sensor for sensing the state of the handle, a power supplier, and a controller configured to block power being supplied to the display, when a sensing value of the sensor indicates a state in which the handle is used.

First claim

What is claimed is:

1. A multimedia device comprising:
a display configured to display multimedia content;
a handle attached to the multimedia device;
a sensor configured to sense whether the handle is in a first state or in a second state used;
a power supplier configured to supply power to the multimedia device; and
a controller configured to control the power supplier to block power being supplied to the display, when a sensing value received from the sensor indicates that the handle is in the first a state;
wherein the first state is a state in which the handle is used in a predetermined fashion and
the second state is a state in which the handle is not used.

2. The multimedia device of claim 1 , wherein the sensor is configured to sense whether the handle is used after the power being supplied to the display is blocked,
wherein the controller is configured to control the power supplier to provide power to the display when the sensing value indicates a state in which the handle is not used, and the display is configured to display the multimedia content when the power is supplied to the display.

3. The multimedia device of claim 1 , wherein the sensor is configured to sense whether the handle is used after the power being supplied to the display is blocked,
wherein when a duration time, during which a sensing value indicating a state in which the handle is used remains constant, is equal to or greater than a set reference time, the controller is configured to control the power supplier to block power being supplied to the multimedia device.

4. The multimedia device of claim 1 , wherein the multimedia device further comprises input circuitry configured to receive a touch-based input,
wherein the controller is configured to receive a sensing value from the sensor when an input indicating entry into a power-saving mode is received from the input circuitry.

5. The multimedia device of claim 1 , wherein the state in which the handle is used comprises a state in which the handle is grasped.

6. The multimedia device of claim 1 , wherein when the handle is configured to act as a stand for the multimedia device, the state in which the handle is used comprises a state in which the handle is folded.

7. The multimedia device of claim 1 , further comprising a communication unit including communication circuitry, the communication unit configured to receive the multimedia content.

8. A method of managing power of a multimedia device, comprising:
providing multimedia content using a multimedia device;
sensing whether a handle attached to the multimedia device is in a first state or in a second state; and
blocking power being supplied to a display of the multimedia device, when a sensing value indicates that the handle is in the first state,
wherein the first state is a state in which the handle is used in a predetermined fashion and the second state is a state in which the handle is not used.

9. The method of claim 8 , further comprising supplying power to the display to display the multimedia content on the display when the sensing value indicates a state in which the handle is not used, after the blocking of power being supplied to the display.

10. The method of claim 8 , further comprising blocking power being supplied to the multimedia device when a duration time during which a sensing value indicating a state in which the handle is used remains constant, is equal to or greater than a set reference time after the blocking of power that is supplied to the display.

11. The method of claim 8 , further comprising receiving a touch-based input indicating entry into a power-saving mode, wherein when the touch-based input is received, sensing of whether the handle is used is performed.

12. The method of claim 8 , wherein the state in which the handle is used comprises a state in which the handle is grasped.

13. The method of claim 8 , wherein when the handle has a form in which the handle acts as a stand for the multimedia device, the state in which the handle is used comprises a state in which the handle is folded.

14. A non-transitory computer-readable recording medium having recorded thereon a program which, when executed, causes the multimedia device to perform the operations of claim 8 .
