The above-described display device 100 can be used as a fixed type of digital broadcasting of ATSC (8-VSB), digital broadcasting of DVB-T (COFDM), digital broadcasting of ISDB-T (BST-OFDM) And may be a digital broadcast receiver capable of receiving at least one.

2, the display device 100 does not include the tuner 110 and the demodulation unit 120 shown in FIG. 2, and the network interface unit 130 or the external device interface unit 135, Through which video content can be received and played back.

3 is an internal block diagram of the control unit shown in FIG. 3 and 2, the following will be described.

The controller 170 according to an exemplary embodiment of the present invention includes a demultiplexing unit 310, an image processing unit 320, an OSD generating unit 340, a mixer 350, a frame rate converting unit 355, 360). A voice processing unit (not shown), and a data processing unit (not shown).

The demultiplexer 310 demultiplexes the input stream. For example, when an MPEG-2 TS is input, it can be demultiplexed into video, audio, and data signals, respectively. The stream signal input to the demultiplexer 310 may be a stream signal output from the tuner 110 or the demodulator 120 or the external device interface 135.

The image processor 320 can perform image processing of the demultiplexed video signal. For this, the image processing unit 320 may include a video decoder 325 and a scaler 335.

The video decoder 325 decodes the demultiplexed video signal and the scaler 335 performs scaling so that the resolution of the decoded video signal can be output from the display unit 180. The video decoder 325 can include a decoder of various standards.

For example, if the demultiplexed video signal is an MPEG-2 standard encoded video signal, it can be decoded by an MPEG-2 decoder.

Also, for example, if the demultiplexed video signal is an encoded video signal of the H.264 standard according to the DMB (Digital Multimedia Broadcasting) scheme or DVB-H, it can be decoded by the H.264 decoder.

Meanwhile, the video signal decoded by the video processor 320 is input to the mixer 350.

The OSD generation unit 340 generates an OSD signal according to a user input or by itself. For example, based on a control signal from the user input interface unit 150, a signal for displaying various kinds of information in a graphic or text format can be generated on the screen of the display unit 180. The generated OSD signal may include various data such as a user interface screen of the display device 100, various menu screens, widgets, icons, and the like.

For example, the OSD generating unit 340 may generate a signal for displaying broadcast information based on a caption of a broadcast image or an EPG.

The mixer 350 may mix the OSD signal generated by the OSD generator 340 and the decoded video signal processed by the image processor 220. The mixed signal is provided to formatter 360. Since the decoded broadcast video signal or the external input signal and the OSD signal are mixed, the OSD can be overlaid on the broadcast image or the external input image.

A frame rate converter (FRC) 355 can convert a frame rate of an input image. For example, a frame rate of 60 Hz is converted to 120 Hz or 240 Hz. When converting the frame rate of 60 Hz to 120 Hz, it is possible to insert the same first frame between the first frame and the second frame, or insert the third frame predicted from the first frame and the second frame. When converting a frame rate of 60 Hz to 240 Hz, it is possible to insert three more identical frames or insert three predicted frames. On the other hand, it is also possible to maintain the input frame rate without performing another conversion.

The formatter 360 receives the output signal of the frame rate conversion unit 355 and changes the format of the signal to be suitable for the display unit 180 and outputs the signal. For example, the R, G, and B data signals may be output as low voltage differential signaling (LVDS) signals or mini-LVDS signals.

On the other hand, the audio processing unit (not shown) in the control unit 170 can perform the audio processing of the demultiplexed audio signal. To this end, the voice processing unit (not shown) may include various decoders.

When a demultiplexed speech signal is a coded speech signal, the speech processing unit (not shown) in the control unit 170 can decode the demultiplexed speech signal. For example, the demultiplexed speech signal may be decoded by an MPEG-2 decoder, an MPEG 4 decoder, an AAC decoder, or an AC-3 decoder.

In addition, the audio processing unit (not shown) in the control unit 170 can process a base, a treble, a volume control, and the like.

The data processing unit (not shown) in the control unit 170 can perform data processing of the demultiplexed data signal. For example, if the demultiplexed data signal is a coded data signal, it can be decoded. The encoded data signal may include EPG (Electronic Program Guide) data including broadcast information such as a start time and an end time of a broadcast program broadcasted on each channel. For example, the EPG data may include ATSC-PSIP (ATSC-Program and System Information Protocol) information in case of the ATSC scheme, and DVB-Service Information .

The ATSC-PSIP information or DVB-SI information may be information included in the above-described stream, i.e., the header (4 bytes) of the MPEG-2 TS.

Hereinafter, embodiments related to a control method that can be implemented in a display device constructed as above will be described with reference to the accompanying drawings. It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Hereinafter, a method of searching for a specific content through a voice uttered by a user in the display device 100 according to an embodiment of the present invention will be described with reference to FIGS. 6 to 21. FIG.

6 is a flowchart for explaining an example of a method of searching for a specific content through a voice uttered by a user in a display device according to an embodiment of the present invention.

In accordance with the first command, the control unit 170 may receive a voice signal corresponding to the voice uttered by the user to search for the specific content (S610).

For example, the first command may be a command to receive a voice signal for searching for a specific content through the voice signal receiver 160 of the display device 100. [ Specifically, when receiving a signal corresponding to a specific key input of the remote control apparatus 200 through the user input interface unit 150, the control unit 170 activates the microphone included in the audio signal receiving unit 160 . The activated microphone may receive a speech uttered by the user (e.g., a voice uttered by the user to search for a specific content) and convert the received voice into an electrical voice signal.

In another example, the first command may be an instruction to receive a voice signal for searching for a specific content through the voice signal receiving unit 245 of the remote control device 200. Specifically, the control unit 280 of the remote control device 200 can activate a microphone included in the voice signal receiving unit 245 in response to a specific key input of the remote control device 200. [ The activated microphone of the remote control device 200 can receive the speech uttered by the user and convert it into an electrical voice signal. The control unit 280 of the remote control device 200 can control the wireless communication unit 235 to transmit the audio signal to the display device 100. [ Accordingly, the display device 100 may receive the voice signal through the user input interface unit 150. [

The control unit 170 may recognize whether a speech recognition language is set in a second language other than the first language used in the service target country (S620). Here, the service target country may mean a country in which the display device 100 is sold, or a country in which the display device 100 is installed. In addition, the speech recognition language may be preset in a language used in the service target country from the time of shipment, and the user may use the speech recognition language in another language.

When the user sets the speech recognition language to a second language different from the first language used in the service target country, the control unit 170 recognizes that the speech recognition language is set to a second language different from the first language .

For example, when it is assumed that the service target country, that is, the country in which the display device 100 is sold, or the country in which the display device 100 is installed is Korea, a Korean language, which is a common language used in Korea, , And the second language may be a language other than Korean (e.g., English).

As another example, when it is assumed that the service target country, that is, the country in which the display device 100 is sold, or the region in which the display device 100 is installed is the United States, Language, and the second language may be a language other than English (e.g., Korean).

If the control unit 170 recognizes that the speech recognition language is set to the first language used in the service target country (S620, No), the control unit 170 transmits the received speech signal through the network interface unit 130 to the first The network interface unit 130 may be controlled so as to be transmitted to the first external server corresponding to the language (S630). Here, the first external server may be a server that receives a voice signal and converts the voice signal into text of a first language. For example, if the first language is Korean, the first external server corresponding to Korean can convert the received voice signal into Korean text.

The first external server may store characteristic information that is displayed when a person using a language other than the first language pronounces the text of the first language.

When transmitting the received voice signal to the first external server, the controller 170 may transmit information indicating that the voice recognition language is set to the first language used in the service target country. Therefore, the first external server recognizes that the speech recognition language is set in the first language, and can convert the speech signal into the text of the first language without using the characteristic information.

The control unit 170 may control the network interface unit 130 to receive the first text corresponding to the voice signal from the first external server (S640).

The control unit 170 may control the display unit 180 to display the search result of the specific content corresponding to the first text received from the first external server at operation S650.

On the other hand, when the control unit 170 recognizes that the speech recognition language is set to a second language different from the first language used in the service target country (S620, Yes), the control unit 170 transmits the received speech signal to the network interface unit 130) to the first external server corresponding to the first language and the second external server corresponding to the second language (S660). Here, the reason why the voice signal is transmitted not only to the second external server corresponding to the second language set in the voice recognition language but also to the first external server corresponding to the first language is that the foreign speaker can speak the voice recognition language in the second language There is a case where specific contents are searched using the first language.

The first external server corresponding to the first language may be a server for receiving a voice signal and converting the voice signal into text of the first language. The first external server may store characteristic information that is displayed when a person using a language other than the first language pronounces the text of the first language.

When transmitting the received voice signal to the first external server, the control unit 170 may transmit information indicating that the voice recognition language is set in the second language. Accordingly, when receiving the voice signal from the first external server, it is recognized that the voice recognition language is set to the second language other than the first language, and a person using the second language For example, if it is assumed that the first language is Korean and the second language is English, the first external server may convert the speech signal into text, After receiving the voice signal, it can be recognized that the voice recognition language is set to English. The first external server can convert the received voice signal into Korean text using characteristic information that is displayed when an American pronounces Korean. Therefore, even if the first external server receives a Korean voice signal uttered by an American who does not speak Korean using an incorrect pronunciation, the first external server can convert the received voice signal into Korean There will be.

Meanwhile, the second external server corresponding to the second language may be a server that receives a voice signal and converts the voice signal into text of the second language. For example, if the second language is English, a second external server corresponding to English may convert the received voice signal into English text. The reason why the voice signal is transmitted to the second external server is that a user desires to search for specific content using the second language.

The control unit 170 receives the first text corresponding to the voice signal from the first external server and transmits the second text corresponding to the voice signal from the second external server to the network interface unit 130 (S670). Wherein the first text includes text of the first language corresponding to a speech recognition result of the speech signal and the second text includes text of the second language corresponding to a speech recognition result of the speech signal can do. For example, assuming that the first language is Korean and the second language is English, the first text includes the Korean text corresponding to the speech recognition result of the speech signal, and the second text includes the speech And may include English text corresponding to speech recognition results of the signal.

The control unit 170 may control the display unit 180 to display the search result of the specific content corresponding to at least one of the received first text and the received second text (S680). Specifically, the control unit 170 displays the search result of the specific content corresponding to the first text in the first area on the screen, and the search result of the specific content corresponding to the second text in the second area The display unit 180 may be controlled so that the display unit 180 is displayed.

According to the embodiment, the control unit 170 determines the priority of the first text and the second text according to a predetermined condition, and determines the priority of the first text and the second text And may control the display unit 180 to display the search result of the corresponding specific content. A detailed description thereof will be described later in more detail with reference to FIGS. 19 to 21. FIG.

According to an embodiment, the control unit 170 may control the display unit 180 such that the received first text and the received second text are displayed together with the search result. This will be described in more detail with reference to Figs. 9, 10, 15 and 16.

According to an embodiment, the control unit 170 includes a first GUI (Graphical User Interface) for confirming a search result of the specific content corresponding to the first text and the second text, and a second GUI And may control the display unit 180 to display a second GUI for confirming the search result of the specific content corresponding to each content. This will be described in more detail with reference to Figs. 11, 12, 17 and 18.

Meanwhile, according to the embodiment, the control unit 170 may convert the speech signal into text of the first language or the second language through a speech recognition program stored in advance in the storage unit 140. [ Here, the speech recognition program may be a program for converting the received speech signal into text. If it is difficult to convert the received voice signal into text using only the voice recognition program stored in the storage unit 140, the control unit 170 transmits the received voice signal through the network interface unit 130 to at least one external And control the operation of the display device using at least one text corresponding to the text recognition result transmitted from the external server. Specifically, when a simple command (for example, a command for changing the volume) is received from the user as a voice signal, the control unit 170 converts the voice signal into text through the voice recognition program, And can execute a specific command corresponding to the recognized text. However, when the control unit 170 receives a complicated command (for example, a command for searching for a specific content) from a user as a voice signal, the control unit 170 can not convert the voice signal into text by using only the voice recognition program, And can control the network interface unit 130 to transmit the voice signal to the server.

If the voice recognition language is set to a second language different from the first language, the control unit 170 controls the network interface unit 130 (not shown) to transmit the voice signal only to the second external server ). If the second text corresponding to the voice signal is received from the second external server and corresponds to a predetermined condition (for example, when there is no search result of the specific content corresponding to the second text) And may transmit the voice signal to the first external server to control the network interface unit 130 to receive the first text from the first external server.

According to the present embodiment, even when the user sets the voice recognition language to a language other than the language used in the service target country of the display device 100, There is an effect that the specific content can be searched by uttering a voice of a language used in the service target country.

Hereinafter, with reference to FIG. 7 to FIG. 12, if the user country is Korea and the voice recognition language is English, the display device 100 according to the embodiment of the present invention, A method of searching will be described. 13 to 18, when the user country is the United States of America and the voice recognition language is Korean, the display device 100 according to the exemplary embodiment of the present invention searches for a specific content through a voice uttered by the user Will be described.

7 is a diagram for explaining an example of a method of setting a speech recognition language in a display device according to an embodiment of the present invention.

For convenience of description of this embodiment, the service target country of the display device 100 is assumed to be Korea and will be described below.

7A, when the control unit 170 receives a signal corresponding to a specific key input of the remote control device 200 through the user input interface unit 150, the menu bar 700 is displayed on the screen The display unit 180 may be controlled to be displayed on the display unit 180. The control unit 170 controls the display unit 710 to display the language setting menu 710 according to a command to select an icon 701 that performs a function of outputting a language setting menu among the icons included in the menu bar 700. [ (180).

The language setting menu 710 includes a first icon 711 for setting the language of the text displayed on the menu, a second icon 712 for setting the language of the audio data output through the audio, And a fourth icon 714 for setting the language of the keyboard output via the screen.

Referring to FIG. 7B, the controller 170 selects the third icon 713 among at least one icon included in the menu 710 for setting the language in FIG. 7A The display unit 180 can be controlled to display a menu 720 for setting a speech recognition language. The user can set a language used in another country as well as Korean, which is a language used as an official language in Korea, as the service target country, through the menu 720 in the speech recognition language. For example, when the user desires to set the speech recognition language to English, when selecting the region 721 corresponding to English in the menu 720 for setting the speech recognition language, Can be set.

According to the present invention, when the user sets the speech recognition language to English and utterances the voice for searching for the specific content in Korean, the controller 170 displays the search result in Korean as well as the search result in English The display unit 180 can be controlled. This will be described in detail with reference to FIG.

FIG. 8 is a view for explaining an example of a method of searching for a specific content using a voice uttered by a user in a display device according to an embodiment of the present invention. With reference to FIG. 8, the contents overlapping with those described with reference to FIG. 7 will not be described again, and the differences will be mainly described below.

For convenience of description of the present embodiment, it is assumed that the service target country of the display device 100 is Korea and the speech recognition language is English. It is assumed that the user intends to search for a specific content called "Infinite Challenge" having a title of Korean, which is the language of the service target country, through the voice recognition function. ("Infinite Challenge") that the user utteres to search for a voice signal.

For example, the first command may be a command to receive a voice signal for searching for a specific content through the voice signal receiver 160 of the display device 100. [ Specifically, when receiving the first signal corresponding to the specific key input of the remote control apparatus 200 through the user input interface unit 150, the control unit 170 controls the microphone included in the audio signal receiving unit 160 Can be activated. Then, the activated microphone can receive a voice (e.g., "undefined") uttered by the user and convert it into an electrical voice signal.

In another example, the first command may be an instruction to receive a voice signal for searching for a specific content through the voice signal receiving unit 245 of the remote control device 200. Specifically, the control unit 280 of the remote control device 200 can activate a microphone included in the voice signal receiving unit 245 in response to a specific key input of the remote control device 200. [ Then, the activated microphone of the remote control device 200 can receive a voice (e.g., "undefined") uttered by the user and convert it into an electric voice signal. The control unit 280 of the remote control device 200 can control the wireless communication unit 235 to transmit the audio signal to the display device 100. [ Accordingly, the display device 100 may receive the voice signal through the user input interface unit 150. [

The control unit 170 can recognize whether or not a second language other than the first language used in the service target country is set as the speech recognition language. Here, since the first language is Korean and the second language is English, the controller 170 can recognize that the second language is not the first language but the speech recognition language.

The control unit 170 recognizes that the speech recognition language is set to English rather than Korean used in Korea, which is a service target country, and transmits the speech signal to a first external server corresponding to Korean and a second external server corresponding to English 2 to the external server. Here, the voice signal may be transmitted to a second external server corresponding to English set in the voice recognition language, as well as to a first external server corresponding to Korean The reason is that Americans can set the speech recognition language to English and search for specific content using Korean. The first external server may be a server for converting the received voice signal into Korean text. The first external server may store characteristic information that is displayed when a person using a language other than the first language pronounces the text of the first language.

When transmitting the received voice signal to the first external server, the control unit 170 may transmit information indicating that the voice recognition language is set to English instead of Korean.

When receiving the voice signal from the first external server, recognizes that the voice recognition language is set to English rather than Korean and uses the specific information displayed when a person using English pronounces Korean, The voice signal can be converted into text. Therefore, the first external server can recognize the Korean language text that is uttered with the correct pronunciation even if the American person utteres the Korean text with a lean pronunciation. For example, even if the first external server receives a voice signal that an American has pronounced " Infinite Challenge "as" undangaged ", the first external server may transmit characteristic information (e.g., Can be recognized as "Infinite Challenge" by using characteristic information for pronouncing 'ah' close to the vowel 'vowel', specific information for pronouncing the vowel 'vowel' closer to the vowel, etc.). Then, the first external server can convert the audio signal into text corresponding to "infinite challenge ".

Meanwhile, the second external server may be a server for converting the received voice signal into English text. For example, when the received voice signal is "undefined ", the second external server transmits the received voice signal to a text

(E.g., "More John"). That is, since the "undhension" is not English, the received voice signal can be converted into a text "More John" corresponding to an English word having similar pronunciation. As mentioned above, "More John" does not correspond to the specific content ("Infinite Challenge") that the user intended to search.

The control unit 170 receives the first text corresponding to the voice signal from the first external server and transmits the second text corresponding to the voice signal from the second external server to the network interface unit 130 Can be controlled. Here, the first text may include a Korean text corresponding to a speech recognition result of the speech signal, and the second text may include English text corresponding to a speech recognition result of the speech signal. For example, the control unit 170 receives an "infinite challenge" as a first text corresponding to the voice signal from the first external server, and receives a second text corresponding to the voice signal from the second external server And can control the network interface unit 130 to receive "More John ".

The control unit 170 may search for specific content corresponding to at least one of the received first text and the received second text.

For example, the control unit 170 extracts EPG (Electronic Program Guide) data included in a broadcast signal received through the tuner 110, and outputs the first text and the second text The specific content corresponding to at least one of the plurality of content items can be searched. The EPG data includes at least one of a channel number, a title of a program being broadcast or scheduled to be broadcast on a channel, a start time of the program, an end time of the program, an elapsed time of the program currently being broadcast, , And contents of the program. Specifically, the control unit 170 searches for the specific content corresponding to the received first text "infinite challenge" and the received second text "More John" using the EPG data extracted from the broadcast signal .

In another example, the control unit 170 may retrieve the specific content corresponding to at least one of the first text and the second text via the network interface unit 130. [ Specifically, the control unit 170 controls the network interface unit 130 to search the Internet for the specific content corresponding to the received first text "Infinite Challenge" and the received second text "More John" .

Specifically, the controller 170 displays the search result of the specific content corresponding to the first text in the first area 810 on the screen 800, and displays the search result of the specific content corresponding to the second text The display unit 180 may be controlled to display the second area 820 on the screen 800.

For example, if the EPG data includes only a broadcast program having a title corresponding to the first text "infinite challenge " and no broadcast program having a title corresponding to the second text" More John & , The control unit 170 may control the display unit 180 to display information about the broadcast program corresponding to the first text in the first area 810 as a search result. Here, the search result may include a thumbnail image of a broadcast program called "Infinite Challenge. &Quot; However, according to the embodiment, the controller 170 may control the display unit 180 to display EPG information of the program in the first area 810.

In another example, when the EPG data includes a broadcast program having a title corresponding to the first text "infinite challenge" and a broadcast program having a title corresponding to the second text "More John" The controller 170 displays information about a broadcast program called "Infinite Challenge" in the first area 810 as a search result, and stores information about the broadcast program "More John" 820 of the display unit 180. [0050]

As another example, when there is a search result of the first text "Infinite Challenge" and the second text "More John " on the Internet, the controller 170 searches the first text" A result (e.g., an Internet address, a thumbnail image of a moving picture, etc.) is displayed in the first area 810, and a search result (e.g., an Internet address, Image, etc.) may be displayed on the second area 820. [0053] FIG.

As another example, if there is no search result of the first text "Infinite Challenge " and only the search result of the second text" More John " exists on the Internet, May be displayed on the second area 820. In another example, the EPG data may be broadcasted with the title corresponding to the first text "infinite challenge & If there is a search result of the second text "More John " on the Internet, the controller 170 searches the information on the broadcast program" Infinite Challenge " The display unit 180 may control the display unit 180 to display the search result of the second text "More John " in the second area 820.

The control unit 170 may control the display unit 180 to display the received first text and the received second text in a predetermined area on the screen 800. [ Accordingly, the user can confirm the first text and the second text that are output on the screen 800, and confirm which text the search was performed.

According to an embodiment, the control unit 170 may include a first GUI 1010 for confirming only the search results of the specific content corresponding to the second text among the first text and the second text, The display unit 180 may be controlled to display on the screen 800 a second GUI 1020 for confirming all the search results of the specific content corresponding to each of the two texts.

The control unit 170 displays the search result of the specific content corresponding to the second text in a predetermined area on the screen 800 according to a command to select the first GUI 1010 And a search result of a specific content corresponding to each of the first text and the second text is displayed on a predetermined area on the screen 800 according to a command to select the second GUI 1020, It is possible to control the unit 180.

The user can set a language used in another country as well as English, which is a language used as a common language in the United States of America, through the menu 720 as the speech recognition language. For example, when the user desires to set the speech recognition language to Korean, when the region 722 corresponding to Korean is selected in the menu 720 for setting the speech recognition language, Can be set.

According to the present invention, when the user sets the speech recognition language to Korean and utteres a voice for searching for the specific content in English, the controller 170 not only displays the search result in Korean but also the search result in English The display unit 180 can be controlled. This will be described in detail with reference to FIG.

FIG. 14 is a view for explaining another example of a method for searching for a specific content using a voice uttered by a user in a display device according to an embodiment of the present invention. With reference to FIG. 14, the contents overlapping with those described with reference to FIG. 13 will not be described again, and the differences will be mainly described below.

For convenience of description of the present embodiment, it is assumed that the service target country of the display device 100 is the United States of America and the voice recognition language is Korean. It is assumed that the user intends to search for a specific content called " House of card "having a title in English, which is the language of the service target country, through the voice recognition function.

According to the first command, the control unit 170 may receive a voice signal corresponding to a voice ("House of card ") uttered by the user to retrieve a specific content.

For example, the first command may be a command to receive a voice signal for searching for a specific content through the voice signal receiver 160 of the display device 100. [ Specifically, when receiving the first signal corresponding to the specific key input of the remote control apparatus 200 through the user input interface unit 150, the control unit 170 controls the microphone included in the audio signal receiving unit 160 Can be activated. The activated microphone can receive a voice (e.g., "House of card") uttered by the user and convert it into an electrical voice signal.

In another example, the first command may be an instruction to receive a voice signal for searching for a specific content through the voice signal receiving unit 245 of the remote control device 200. Specifically, the control unit 280 of the remote control device 200 can activate a microphone included in the voice signal receiving unit 245 in response to a specific key input of the remote control device 200. [ The activated microphone of the remote control device 200 can receive a voice (e.g., "House of card") uttered by the user and convert it into an electrical voice signal. The control unit 280 of the remote control device 200 can control the wireless communication unit 235 to transmit the audio signal to the display device 100. [ Accordingly, the display device 100 may receive the voice signal through the user input interface unit 150. [

The control unit 170 can recognize whether or not a second language other than the first language used in the service target country is set as the speech recognition language. Here, since the first language is English and the second language is Korean, the controller 170 can recognize that the second language other than the first language is set as the speech recognition language.

The control unit 170 recognizes that the speech recognition language is set to Korean rather than the language used in the United States of America, which is a service target country, and transmits the speech signal to a first external server corresponding to English and a second external server corresponding to Korean 2 to control the network interface unit 130 to transmit to the external server. Here, the reason why the voice signal is transmitted not only to the second external server corresponding to the Korean language set in the voice recognition language but also to the first external server corresponding to English is because Korean sets the voice recognition language to Korean, You can also search for content.

The first external server may be a server for converting the received voice signal into English text. The first external server may store characteristic information that is displayed when a person using a language other than the first language pronounces the text of the first language.

When transmitting the received voice signal to the first external server, the control unit 170 may transmit information indicating that the voice recognition language is set to Korean, which is not English.

When receiving the voice signal from the first external server, recognizes that the voice recognition language is set to English rather than Korean and uses the specific information displayed when a person using English pronounces Korean, The voice signal can be converted into text. Accordingly, the first external server can recognize the Korean language as English text that is uttered with accurate pronunciation, even if the Korean language utteres the English text with a lean pronunciation. For example, although the first external server receives a voice signal in which a Korean person has not properly pronounced the " House of card " and converts the voice signal into an electrical signal, the first external server transmits character information For example, a Korean accent, specific information that a Korean person pronounces when pronouncing 'r', etc.) as a "House of card". The first external server can convert the audio signal into a text "House of card ".

Meanwhile, the second external server may be a server for converting the received voice signal into Korean text. For example, if the received voice signal is "House of card ", the second external server may convert the received voice signal into Korean text (e.g.," House of cards "). Here, since the "House of card" is not Korean, the received voice signal may be converted into a text corresponding to a Korean word having similar pronunciation. However, the following description assumes that the " House of card ", which is the voice uttered by the user at the second external server, can be converted into " The first text corresponding to the voice signal from the second external server and the second text corresponding to the voice signal from the second external server. Here, the first text may include a text of English corresponding to a speech recognition result of the speech signal, and the second text may include a text of Korean corresponding to a speech recognition result of the speech signal. For example, the control unit 170 receives a first text "House of card" corresponding to the voice signal from the first external server, and receives a second text corresponding to the voice signal from the second external server The " House of Cards ".

The control unit 170 may search for specific content corresponding to at least one of the received first text and the received second text.

For example, the control unit 170 extracts EPG (Electronic Program Guide) data included in a broadcast signal received through the tuner 110, and outputs the first text and the second text The specific content corresponding to at least one of the plurality of content items can be searched. The EPG data includes at least one of a channel number, a title of a program being broadcast or scheduled to be broadcast on a channel, a start time of the program, an end time of the program, an elapsed time of the program currently being broadcast, , And contents of the program. Specifically, the control unit 170 uses the EPG data extracted from the broadcast signal to determine whether the received first text "House of card" and the received second text " You can search for specific content.

In another example, the control unit 170 may retrieve the specific content corresponding to at least one of the first text and the second text via the network interface unit 130. [ Specifically, the control unit 170 controls the network interface unit 130 to search for the specific content corresponding to the received first text "House of card" and the received second text " Can be controlled.

The control unit 170 searches for the specific content corresponding to at least one of the first text and the second text using the EPG data included in the broadcast signal, Text and the second text corresponding to at least one of the first text and the second text. That is, the control unit 170 may search the specific content through the network interface unit 130 while searching for the specific content using the EPG data. If the specific content is not retrieved using the EPG data, The specific content may be searched through the unit 130. However, the present invention is not limited thereto.

The control unit 170 may control the display unit 180 to display the search result of the specific content corresponding to at least one of the received first text and the received second text. Specifically, the controller 170 displays the search result of the specific content corresponding to the first text in the first area 810 on the screen 800, and displays the search result of the specific content corresponding to the second text The display unit 180 may be controlled to display the second area 820 on the screen 800.

For example, since the service target country is the United States, the EPG data includes only a broadcast program having a title corresponding to the first text "House of card ", and the second text A broadcast program having a title may not exist. Accordingly, the controller 170 may control the display unit 180 to display information on the broadcast program corresponding to the first text in the first area 810 as a search result. Here, the search result may include a thumbnail image of a broadcast program called "House of card ". However, the controller 170 may control the display unit 180 to display EPG information of the program in the first area 810 according to the embodiment.

In another example, when there is a search result of the first text "House of card" and the second text "House of Card" on the Internet, the controller 170 reads the first text & (E.g., an Internet address, a thumbnail image of a moving picture, and the like) of the second text is displayed in the first area 810, and the search result (e.g., Internet address, A thumbnail image of a moving picture, etc.) may be displayed in the second area 820. [

As another example, if there is no search result of the first text "House of card " on the Internet and only the search result of the second text" House of Card "exists, Of card "may be displayed in the second area 820. The display unit 180 may be configured to display the search results of the "

In another example, the EPG data includes a broadcast program having a title corresponding to the first text "House of card ", and the search result of the" House of Card " The controller 170 displays information about a broadcast program called " House of card "in the first area 810 as a search result, and stores the search result of the " House of Card " The display unit 180 may be controlled to display the second area 820.

The control unit 170 may control the display unit 180 to display the received first text and the received second text in a predetermined area on the screen 800. [ The user can confirm the first text and the second text outputted on the screen 800 and confirm which text is used for the search.

According to an embodiment, the control unit 170 may include a first GUI 1010 for confirming only the search results of the specific content corresponding to the second text among the first text and the second text, The display unit 180 may be controlled to display on the screen 800 a second GUI 1020 for confirming all the search results of the specific content corresponding to each of the two texts.

The control unit 170 displays the search result of the specific content corresponding to the second text in a predetermined area on the screen 800 according to a command to select the first GUI 1010 And a search result of a specific content corresponding to each of the first text and the second text is displayed on a predetermined area on the screen 800 according to a command to select the second GUI 1020, It is possible to control the unit 180. This will be described later in more detail with reference to FIGS. 17 and 18. FIG.

Conventionally, when a speech recognition language is set in a second language other than the first language used in a country in which a display device is sold or a country in a region in which a display device is installed, when a user uses a first language There was a problem that the content could not be found. In addition, when the speech recognition language is set in the first language and the specific content is searched using the first language, the specific content is searched through accurate pronunciation and accurate accent so that the search result of the specific content desired by the user is outputted I could. That is, there is a problem that if a foreigner uses a first language to search for a specific content and utteres a wrong pronunciation and an incorrect accent, an incorrect result is output. However, according to the present embodiment, even if a speech recognition language is set in a second language other than the first language used in a country where a display device is sold or a country in a region where a display device is installed, Can be used to find specific content. In addition, according to the present embodiment, when a user sets a speech recognition language as a second language and searches for a specific content using the first language, even if the first language is spoken as an incorrect pronunciation and an incorrect accent, Can be output.

According to the present invention, the control unit 170 displays a search result of a specific content corresponding to the selected text on the screen according to a command to select any one of the first text and the second text displayed on the screen The display unit 180 can be controlled. This will be described in more detail with reference to FIGS. 15 and 16. FIG.

15 and 16 are diagrams for explaining another example of a method of displaying a search result of a specific content on a screen by using a voice uttered by a user in a display device according to an embodiment of the present invention. With respect to Figs. 15 and 16, the contents overlapping with those described above with reference to Figs. 13 and 14 will not be described again, and the differences will be mainly described below.

For convenience of description of the present embodiment, it is assumed that the service target country of the display device 100 is the United States of America and the voice recognition language is Korean. It is assumed that the user intends to search for a specific content called " House of card "having a title in English, which is the language of the service target country, through the voice recognition function.

This will be described in more detail with reference to FIGS. 17 and 18. FIG.

17 and 18 are views for explaining another example of a method of displaying a search result of a specific content on a screen by using a voice uttered by a user in a display device according to an embodiment of the present invention. With reference to Figs. 17 and 18, the contents overlapping with those described above with reference to Figs. 13 and 14 will not be described again, and the following description will focus on the differences.

For convenience of description of the present embodiment, it is assumed that the service target country of the display device 100 is the United States of America and the voice recognition language is Korean. It is assumed that the user intends to search for a specific content called " House of card "having a title in English, which is the language of the service target country, through the voice recognition function.

According to the present embodiment, the control unit 170 generates a voice signal for searching for a specific content according to the first command (for example, a voice uttered by the user to search for a specific content (e.g., "House of card Quot;) into an electrical signal) from the audio signal received by the audio signal receiving unit 160. [ Since the speech recognition language is set in Korean rather than English used in the service target country, the control unit 170 transmits the voice signal received through the voice signal receiver to the first external server corresponding to the English and the Korean To the second external server corresponding to the second external server. The control unit 170 receives the first text corresponding to the voice signal from the first external server (e.g., "House of card ", text) For example, the text "House of Cards") from the second external server. The control unit 170 may control the display unit 180 to display the search result of the specific content corresponding to at least one of the received first text and the second text.

According to an embodiment, the control unit 170 includes a first GUI 1010 for confirming a search result of a specific content corresponding to the second text among the first text and the second text, 2 text to display the second GUI 1020 for confirming the search result of the specific content corresponding to each of the texts. The control unit 170 may control the display unit 180 such that the first GUI 1010 and the second GUI 1020 are displayed together with the search result, The display unit 180 may be controlled such that the first GUI 1010 and the second GUI 1020 are displayed.

17, in response to a command to select the first GUI 1010, the control unit 170 displays a search result of a specific content corresponding to the second text on a predetermined area 830 on the screen It is possible to control the unit 180. For example, in accordance with a command to select the first GUI 1010, the control unit 170 displays only a search result of a specific content corresponding to the second text "House of Cards" The display unit 180 may be controlled so that the display unit 180 is displayed.

According to the present embodiment, when the user wishes to search only in the language set in the speech recognition language, the first GUI 1010 can be selected so that the search result is output only in the language set in the speech recognition language .

Referring to FIG. 18, in accordance with a command to select the second GUI 1020, the controller 170 searches for a search result of a specific content corresponding to the one text and a search result of a specific content corresponding to the second text And can control the display unit 180 to display on the screen. Specifically, the control unit 170 can control the display unit 180 to display the search result of the specific content corresponding to the first text "House of Cards" in the first area 810 on the screen, It is possible to control the display unit 180 to display the search result of the specific content corresponding to the second text "House of Cards " in the second area 820 on the screen.

According to the present embodiment, the user can select the second GUI 1020 and output all the search results of the specific content corresponding to the first text and the second text.

According to an embodiment of the present invention, the priority of the first text and the second text is determined, and the search of the specific content corresponding to the high priority text among the first text and the second text Results may also be displayed. This will be described in more detail with reference to FIGS. 19 to 21. FIG.

19 is a flowchart illustrating an example of a method of displaying search results of specific content according to the priority of text received from at least one external server in a display device according to an embodiment of the present invention. With reference to FIG. 19, the contents overlapping with those described above with reference to FIG. 6 will not be described again, and the differences will be mainly described below.

The control unit 170 may receive a voice as a voice signal for searching for a specific content uttered by the user according to the first command. If the voice recognition language is set to a second language that is different from the first language used in the service target country, the control unit 170 controls the first external server corresponding to the first language through the network interface unit 130, And to control the network interface unit 130 to transmit the received voice signal to a second external server corresponding to the second language. The control unit 170 receives the first text corresponding to the voice signal from the first external server and transmits the second text corresponding to the voice signal from the second external server to the network interface unit 130 Can be controlled.

The control unit 170 may determine the priority of the first text and the second text according to a predetermined condition (S681). Specifically, the priority may be determined based on whether the text corresponding to the voice signal is text corresponding to a specific content currently being broadcasted or scheduled to be broadcast on a specific channel, or a text corresponding to a specific content in which a search history exists And information on the text corresponding to the specific content in which the viewing history is present. For example, a text corresponding to a specific content currently broadcasted on a specific channel has the highest priority, a text corresponding to a specific content scheduled to be broadcast in a specific channel, a text corresponding to a specific content in which a viewing history exists, The priority order can be determined in the order of the text corresponding to the specific content present. According to an exemplary embodiment, the predetermined condition for determining the priority may be periodically or non-periodically updated according to a specific signal received from an external server.

According to the embodiment, the control unit 170 may determine the priority of the first text and the second text according to a predetermined condition only when the user sets it through a menu.

The control unit 170 can recognize the high priority text among the received first text and the received second text (S682).

For example, if the first text is text corresponding to a title of a specific content currently being broadcast on a specific channel, the controller 170 recognizes the received first text as a text having a higher priority than the second text can do.

Alternatively, if the first text is a text corresponding to a specific content currently being broadcast in a specific channel and the second text is a text corresponding to a specific content in which a search history exists, The text can be recognized as a text having a higher priority than the second text.

As another example, when the first text is a text corresponding to a specific content in which a search history exists, and the second text is text corresponding to a specific content in which a viewing history exists, It can be recognized as text having a higher priority than the text.

The control unit 170 may control the display unit 180 to display the search result of the specific content corresponding to the text having the high priority (S683). When the search result of the specific content corresponding to the high priority text is displayed, the probability that the search result of the specific content desired by the user is displayed is increased.

For example, when the first text and the first text are high-priority text, the controller 170 displays a search result of the specific content corresponding to the first text having a high priority The display unit 180 can be controlled.

In another example, when the second text of the first text and the second text are high-priority text, the controller 170 displays the search result of the specific content corresponding to the second text having the high priority The display unit 180 can be controlled.

According to an embodiment, if the first text and the second text have the same priority, the display unit 180 is controlled to display a search result of the specific content corresponding to the first text and the second text It is possible.
