Movable TV and method for controlling the same

1 . A method for controlling a movable display apparatus, the method performed by the movable display apparatus including a network interface configured to receive a signal including content, a speaker configured to output audio data of the content, a display configured to output video data of the content, and a controller configured to control output of the audio data and the video data, the method comprising:

outputting the audio data of the content via the speaker and the video data of the content via the display while the display is located at a first location;

in response to the movable display apparatus being moved from the first location to a second location, lowering a volume level of the audio data being output from the speaker to a predetermined volume level and outputting a guide voice indicating that the movable display apparatus is moving;

in response to the movable display apparatus being moved to the second location, receiving state information of an external device located around the second location, wherein the state information indicates noise caused by the external device; and

raising a volume level of the audio data being output via the speaker while maintaining the output of the video data via the display according to the received state information.

2 . The method of claim 1 , wherein the lowered volume level of the audio data is at least two times lower than a volume level of the guide voice.

3 . The method of claim 2 , further comprising:

raising the volume level of the audio data and no longer outputting the guide voice based on detecting that the movable display apparatus has not been moved for a predetermined time period or more.

4 . The method of claim 1 , wherein the external device is configured to generate noise from vibration during operation.

5 . The method of claim 1 , further comprising:

receiving the state information from a plurality of external devices located around the second location, the state information indicating noise caused by the plurality of external devices;

calculating total noise level using the noise caused by the plurality of external devices; and

raising the volume level of the audio data being output according to the noise caused by the plurality of external devices.

6 . The method of claim 5 , further comprising:

learning a pattern of noise caused by at least one of the plurality of external devices when the noise caused by the at least one of the plurality of external devices is not received from a server.

7 . The method of claim 6 , further comprising:

mapping the state information of the at least one of the plurality of external devices to the learned pattern of the noise and storing the mapping in a memory.

8 . The method of claim 7 , further comprising:

outputting a destructive interference wave using the stored mapping when the noise caused by the at least one of the plurality of external devices is not received from the server.

9 . A movable display apparatus comprising:

a speaker configured to output audio data of content while the display is located at a first location;

a display configured to output video data of the content while the display is located at the first location;

a network interface; and

a controller configured to:

detect that the display is being moved from the first location to a second location;

in response to that the movable display apparatus is being moved from the first location to a second location, lower a volume level of the audio data being output from the speaker to a predetermined volume level and output a guide voice indicating that the movable display apparatus is moving;

in response to that the movable display apparatus has been moved to the second location, receive, via the network interface, state information of an external device located around the second location, wherein the state information indicates noise caused by the external device; and

raise a volume level of the audio data being output while maintaining the output of the video data according to the noise indicated by the received state information.

10 . The movable display apparatus of claim 9 , wherein the lowered volume level of the audio data is at least two times less than a volume level of the guide voice.

11 . The movable display apparatus of claim 10 , wherein the controller is further configured to raise the volume level of the audio data and no longer output the guide voice based on detecting that the movable display apparatus has not been moved for a predetermined time period or more.

12 . The movable display apparatus of claim 9 , wherein the external device is configured to generate noise from vibration during operation.

13 . The movable display apparatus of claim 9 , wherein the controller is further configured to:

receive the state information from a plurality of external devices located around the second location, the state information indicating noise caused by the plurality of external devices;

calculate total noise level using the noise caused by the plurality of external devices; and

raise the volume level of the audio data being output according to the noise caused by the plurality of external devices.

14 . The movable display apparatus of claim 13 , wherein the controller is further configured to learn a pattern of noise caused by at least one of the plurality of external devices when the noise caused by the at least one of the plurality of external devices is not received from a server.

15 . The movable display apparatus of claim 14 , wherein the controller is further configured to:

map the state information of the at least one of the plurality of external devices to the learned pattern of the noise and store the mapping in a memory.

16 . The movable display apparatus of claim 15 , wherein the controller is further configured to output a destructive interference wave using the stored mapping when the noise caused by the at least one of the plurality of external devices is not received from the server.
