Display device and method for operating same
A display device according to an embodiment of the present invention may comprise: an audio output unit; a display unit that displays a first image and a second image; and a control unit that, when the first image is focused from among the first image and the second image, outputs a first voice corresponding to the first image through the audio output unit, converts a second voice corresponding to an unfocused second image into text, and displays the converted text on the second image.
1 . A display device comprising:
a speaker;
a display configured to display a first video at a first area of the display and to display a second video at a second area of the display; and
a controller configured to:
based on the first video being focused from among the first video and the second video:
output a first voice corresponding to the first video through the speaker, without outputting, through the speaker, a second voice corresponding to the second video which is not focused;
extract voice data corresponding to the second voice of the second video;
convert the voice data corresponding to the second voice into text; and
display the text to be superimposed on the second video displayed at the second area.
2 . The display device of claim 1 , wherein the controller is further configured to determine that the first video is focused based on receiving a command to select the first video from a remote control device.
3 . The display device of claim 1 , wherein the controller is further configured to output a notification indicating that a keyword is included when the text includes a preset keyword.
4 . The display device of claim 1 , further comprising:
a network interface configured to communicate with a first counterpart device and a second counterpart device.
5 . The display device of claim 4 , wherein the first video which is focused is a first conference video received from the first counterpart device, and the second video which is not focused is a second conference video received from the second counterpart device.
6 . The display device of claim 5 , wherein the controller is further configured to receive a spoken voice uttered by a user from a remote control device and transmit the received spoken voice to the first counterpart device.
7 . The display device of claim 1 , further comprising:
a network interface configured to communicate with a first external device; and
an external device interface connected to a second external device,
wherein the first video which is focused is a conference video received from the first external device via the network interface, and the second video which is not focused is an external input video received from the second external device via the external device interface.
8 . A method for operating a display device, the method comprising:
displaying a first video at a first area of a display of the display device;
displaying a second video at a second area of the display; and
based on the first video being focused from among the first video and the second video:
outputting a first voice corresponding to the first video through a speaker of the display device, without outputting, through the speaker, a second voice corresponding to the second video which is not focused;
extracting voice data corresponding to the second voice of the second video:
converting the voice data corresponding to the second voice into text; and
displaying the text to be superimposed on the second video displayed at the second area.
9 . The method of claim 8 , further comprising:
determining that the first video is focused based on receiving a command to select the first video from a remote control device.
10 . The method of claim 8 , further comprising:
outputting a notification indicating that a keyword is included when the text includes a preset keyword.
11 . The method of claim 8 , wherein the first video which is focused is a first conference video received from a first counterpart device, and the second video which is not focused is a second conference video received from a second counterpart device.
12 . The method of claim 11 , further comprising:
receiving a spoken voice uttered by a user from a remote control device; and
transmitting the received spoken voice to the first counterpart device.
13 . The method of claim 8 , wherein the display device includes a network interface configured to communicate with a first external device, and an external device interface connected to a second external device, and
wherein the first video which is focused is a conference video received from the first external device via the network interface, and the unfocused second video is an external input video received from the second external device via the external device interface.
