Abstract

A digital television can include a display; an interface to receive a control signal from a remote controller; a communication unit for internet access; a broadcast receiver; and a controller to display broadcast content received through the broadcast receiver, display a screen corresponding to a voice recognition mode in response to entering the voice recognition mode, the screen includes a symbol and text indicating the voice recognition mode, receive a voice command signal corresponding to a voice command through the remote controller in the voice recognition mode while the broadcast content is displayed, in which the voice command is input via a microphone provided in the remote controller, and the input voice command includes a search source and a search keyword, and display a web page corresponding to the search source included in the voice command, which includes a search window including the search keyword and a search result.

Claims

1. A digital television comprising:

a display;

an interface configured to receive a control signal for controlling an operation of the digital television from a remote controller;

a communication unit configured to support internet access;

a broadcast receiver configured to receive broadcast signals or broadcast associated information from an external broadcast management server via a broadcast channel; and

a controller configured to;

display broadcast content received through the broadcast receiver on the display,

display a screen corresponding to a voice recognition mode on the display in response to entering the voice recognition mode, wherein the screen includes a symbol and text indicating the voice recognition mode,

receive a voice command signal corresponding to a voice command through the remote controller in the voice recognition mode while the broadcast content is displayed, wherein the voice command is input via a microphone provided in the remote controller, wherein the input voice command is a single voice command including a first part defining an Internet based search engine successively followed by a second part defining a search keyword, and

display a web page corresponding to the Internet based search engine included in the voice command,

wherein the received voice command comprises natural language,

wherein the search keyword is extracted from the natural language based on Natural Language Processing (NPL),

wherein the web page includes a search window including the search keyword,

wherein the web page includes a search result corresponding to the search keyword, and

wherein the web page corresponds to a web site corresponding to the Internet based search engine accessed through the Internet.

2. The digital television of claim 1, wherein the Internet based search engine includes a web page name.

3. The digital television of claim 1, wherein the search keyword includes at least one of a broadcast program name, a person'"'"'s name, a genre of a broadcast program, and an application name.

4. The digital television of claim 1, wherein the remote controller is a mobile terminal configured to control the digital television.
