Display apparatus and operating method therefor
The present disclosure is to solve a problem that, when sound is not output because a sound output device is changed, this is mistaken as a defect of a display apparatus, and the present disclosure may comprise: a display which outputs an image; an audio output unit which outputs sound according to the image through an internal speaker, a wired connection device, or a wireless connection device; and a control unit which obtains audio through a microphone when a connection with the wireless connection device is released, and outputs a message requesting confirmation of settings of the sound output device on the basis of a change in audio volume level.
1 . A display device comprising:
a display which outputs an image;
a sound output device which outputs sound according to the image through an internal speaker, a wired connection device, or a wireless connection device based on settings of the sound output device; and
a control unit configured to:
turn on a microphone connected to the display device when a connection with the wireless connection device is released,
obtain audio output from the sound output device through the microphone for a predetermined period of time based on the connection with the wireless connection device being released, and
output a message requesting confirmation of the settings of the sound output device when there is no change in an audio volume level of the audio obtained through the microphone.
2 . The display device of claim 1 , wherein the control unit is further configured to:
display a menu for receiving selection of the sound output device,
receive a command for selecting an icon of the menu, and
set the selected sound output device.
3 . The display device of claim 1 , wherein the controller is configured to perform control such that the microphone is turned on when the connection with the wireless connection device is released and the sound output device is set to the wired connection device, and acquire the audio recorded for the predetermined period of time including a section in which the audio volume level is changed according to a command for changing the audio volume level.
4 . The display device of claim 3 , wherein the control unit is configured to perform control such that the microphone is turned on when the sound output device switches from the wireless connection device to the wired connection device.
5 . The display device of claim 3 , wherein the control unit is configured to perform control such that the microphone is turned on when a command for changing a volume level is received from a remote control device after the connection with the wireless connection device is released.
6 . The display device of claim 1 , wherein the control unit is configured to acquire the audio including a section for changing the audio volume level according to a command for changing a volume level, which is received from a remote control device after the microphone is turned on.
7 . The display device of claim 1 , wherein the control unit is configured to automatically change the audio volume level in a gradual manner after the microphone is turned on and acquire the audio including a section in which the audio volume level is changed.
8 . The display device of claim 1 , wherein the control unit is configured to filter a third audio to exclude ambient noise by comparing a first audio input along with the image to the display device with a second audio acquired through the microphone, and output a message requesting confirmation of the settings of the sound output device when there is no change in the audio volume level of the third audio.
9 . The display device of claim 1 , wherein the control unit is configured not to re-output the message until there is a change in the settings of the sound output device after the message is output.
10 . The display device of claim 1 , wherein the microphone includes at least one of an internal microphone or a microphone provided in a remote control device, and the control unit is configured to acquire the audio through at least one of the internal microphone or the microphone provided in the remote control device.
