Abstract

A display device according to an embodiment disclosed herein may include a controller for receiving an audio signal and determining whether the received audio signal is an alarm signal. A display device according to an embodiment disclosed herein may include: a microphone for receiving an audio signal; a controller for determining whether the audio signal is an alarm signal; and a speaker for outputting a signal corresponding to the alarm signal. A display device according to an embodiment disclosed herein may include a display for outputting a signal corresponding to an alarm signal.

Claims (35)

1 . A display device comprising:

a microphone receiving an audio signal;

a controller determining whether the audio signal is an alarm signal; and

a speaker outputting a signal corresponding to the alarm signal,

wherein the controller:

extracts a music signal from the received audio signal, and

registers the extracted music signal as an alarm signal based on the extracted music signal being received at a predetermined time or at a predetermined period.

2 . The display device of claim 1 , further comprising:

a display outputting a signal corresponding to the alarm signal.

3 . The display device of claim 2 ,

wherein the controller recognizes a trigger signal added to an alarm signal among the audio signals and outputs a signal corresponding to the trigger signal.

4 . The display device of claim 3 ,

wherein the trigger signal is connected to and added to an end portion of the alarm signal.

5 . The display device of claim 3 ,

wherein the controller recognizes the trigger signal and generates a control signal corresponding to the trigger signal to drive at least one of the speaker or the display.

6 . The display device of claim 3 ,

wherein the controller recognizes the trigger signal, generates a control signal corresponding to the trigger signal, and transmits the control signal to a peripheral device.

7 . The display device of claim 2 ,

wherein when an alarm signal is recognized, the controller displays a QR code or barcode on the display and provides connection to a user device.

8 . The display device of claim 2 ,

wherein when an alarm signal is recognized, the controller generates a control signal set corresponding to the recognized alarm signal and drives at least one of the speaker or the display.

9 . The display device of claim 1 ,

wherein the audio signal received by the microphone includes a voice signal and a music signal, and

wherein the controller determines whether the received music signal is an alarm signal.

10 . The display device of claim 1 ,

wherein the controller:

registers the extracted music signal as an alarm signal, for the extracted music signal, based on at least one of a similarity comparison value with a music signal stored in a database, a reception time coincidence comparison value, or a reception period comparison value satisfying a preset criterion.

11 . The display device of claim 10 ,

wherein a music signal that is not received again until a certain period of time has elapsed among the music signals registered as the alarm signals is released from the registered alarm signal.

12 . The display device of claim 1 ,

wherein the audio signal is generated from a device located around the microphone.

13 . The display device of claim 1 ,

wherein the controller outputs an audio signal or a video signal to inquire whether to register an alarm based on an alarm signal being recognized.

14 . The display device of claim 1 ,

wherein when an alarm signal is recognized, the controller transmits a control signal set corresponding to the recognized alarm signal to a peripheral device.
