Abstract

A display device according to an embodiment of the present disclosure comprises: a display unit; a user input interface unit which receives a signal from a remote control device; and a control unit which receives a voice signal, and on the basis of data extracted from the voice signal, sets an external device connected to the display device as an object to be controlled by the remote control device.

First claim

The invention claimed is:

1. A display device comprising:
a display configured to display content of an external device;
a user input interface configured to receive a signal from a remote control device; and
a controller configured to:
receive a voice signal expressing an intention of setting the external device as a control target of the remote control device;
extract, from the voice signal, data comprising at least one of a type of the external device, a service provider of the external device, a manufacturer of the external device, or an external input terminal to which the external device is connected;
determine whether the extracted data comprises all data required for setting the remote control device;
receive an additional input signal through the user input interface or an additional voice signal to acquire all of the required data among the type of the external device, the service provider of the external device, the manufacturer of the external device and the external input terminal, based on determining that the extracted data does not comprise all of the required data;
set the external device to be controlled by the remote control device based on the extracted data and the additional input signal; and
control the external device using the remote control device.

2. The display device according to claim 1 , wherein, when receiving a control command of the external device in a state in which the content of the external device that is not set as the control target of the remote control device is being displayed, the controller is further configured to perform an operation for setting the external device as the control target of the remote control device.

3. The display device according to claim 2 , wherein, when receiving the control command of the external device in the state in which the content of the external device that is not set as the control target of the remote control device is being displayed, the display is further configured to display a screen that guides the setting of the external device as the control target of the remote control device.

4. The display device according to claim 1 , wherein, when receiving the voice signal for setting the external device as the control target of the remote control device, the controller is further configured to:
acquire a number of external input terminals connected to the external device; and
receive a selection command of the external input terminal, to which the external device set as the control target of the remote control device is connected, when the external input terminal connected to the external device is provided in plurality.

5. The display device according to claim 1 , wherein, when receiving the voice signal for setting the external device as the control target of the remote control device, the controller is further configured to:
acquire a number of external input terminals connected to the external device;
recognize the external input terminal, to which the external device is connected, when there is one external input terminal to which the external device is connected; and
set the external device connected to the recognized external input terminal as the control target of the remote control device.

6. The display device according to claim 1 , wherein, when receiving a command for setting the external device connected to the display device as the control target of the remote control device through the voice signal, the controller is further configured to:
acquire a number of external input terminals connected to the external device; and
receive a selection command of the external device to be set as the control target of the remote control device when the external device connected to the display device is provided in plurality.

7. The display device according to claim 1 , wherein, when the data extracted from the voice signal comprises all data for setting the external device as the control target of the remote control device, the controller is further configured to set the external device connected to the display device as the control target of the remote control device based on the data extracted from the voice signal.

8. The display device according to claim 1 , wherein the display is further configured to display types of data required for setting the external device as the control target of the remote control device.

9. The display device according to claim 8 , wherein the display is further configured to display data, which is not extracted from the voice signal among the data for setting the external device as the control target of the remote control device, as a type of required data.

10. The display device according to claim 9 , wherein the controller is further configured to receive the additional input signal after displaying the type of required data through the display.

11. The display device according to claim 10 , wherein the controller is further configured to set the external device as the control target of the remote control device by using the data extracted from the voice signal and data depending on the additional input signal.

12. The display device according to claim 1 , wherein the controller is further configured to:
determine whether the external device requires a key test based on the data extracted from the voice signal;
when it is determined that the external device connected to the display device requires the key test, output a key test screen through the display;
execute the key test to install corresponding control information in the remote control device;
acquire the control information necessary for controlling the external device through the remote control device; and
allow the user to control the external device using the remote control device based on the control information.

13. The display device according to claim 1 , wherein the controller is further configured to:
acquire audio uttered by the user through a voice acquisition module;
convert the acquired audio through a STT (speech-to-text) module into text data; and
analyze the intention to start setting of the remote controller based on the text data through an NLP (natural language processing) module.
