According to an embodiment of the present invention, when a user inputs a search for a broadcast program related to a video content currently being displayed while a search function and an on-demand service of the display device 100 are being executed, the controller 380 receives the input search word externally. The communication unit 350 is controlled to be transmitted to the server 250, and the external server 200 includes a search word input by a user, information on image content (eg, EPG information, captured screen and metadata, etc.), and other search words. The image information desired by the user may be extracted using information related to (eg, a search word previously searched by the user, a search record of other viewers for image content), and the like. Thereafter, the control unit 380 of the display apparatus 100 may provide image information related to the search word input by the user received from the external server 200. For example, as shown in FIG. 8A, it is assumed that the user incorrectly inputs'Search for a broadcast program in which Jeon Ji-Hoi appears' (810). As described above, the external server 200 uses the received incorrectly entered search word 810 and information on video content (for example, EPG information, captured screen and metadata, etc.) to the viewers in the search record. It is possible to extract information about the information, and extract a recommended broadcast program in which'Jeon Ji-hyun', which is highly related to the search word'Jeon Jeon Hyeon,' incorrectly entered by the user, appears. Thereafter, in the same manner as in the above-described embodiment, the control unit 380 of the display device compares and analyzes the search word input by the user in real time based on the information on the search records of viewers received from the external server 200, It is possible to display a list of edited search words related to the entered'Jeon Jeon Hyeon... (omitted)' (① Jeon Ji-hyun broadcasting program recommendation, 820). Thereafter, as shown in FIG. 8B, a list of recommended image information 810 related to a search word input by a user received from the external server 200 may be displayed.

Meanwhile, in the above-described embodiment, it has been described that the external server 200 extracts a broadcast program in which'Jeon Ji-hyun' (modified search word Jeon Ji-hyun) appears using the received EPG information, and transmits it to the display device 100. This is just an example.

That is, the external server 200 extracts not only the EPG information, but also the contents corresponding to the user's input intention among contents stored in another external device (eg, a DVD device) connected to the VOD service and the display device 100 , The extracted search result may be transmitted to the display device 100.

In this case, as shown in FIG. 9B, the display apparatus 100 may display the recommended image information Lists 930 and 940 by dividing the searched content for each service. For example, when a broadcast program in which'Jeon Ji-hyun' (name of the performer) appears is searched for from EPG information and a DVD player connected to the display device 100, the display device 100 is a recommended video including the broadcast program searched from the EPG information. The information list 930 and the recommended video information list 940 including the DVD content retrieved from the DVD player may be displayed on one screen.

In the above-described embodiment, it is assumed that the search word input by the user is corrected to display the corrected search word list, and then the recommended broadcasting program list related to the modified search word is displayed. This is only an embodiment, and the user If not inputted, it may be applied to an embodiment of displaying a list of recommended search words and a list of related broadcast programs. For example, as shown in FIG. 9A, when a user does not input a search word in relation to the image content currently being displayed while the search function and the ondemand service of the display device are being executed, the controller 380 provides information on the image content. (E.g., EPG information, captured screen and metadata, etc.) are transmitted to the external server 200, and the external server 200 provides information on video content and pre-stored information (for example, the user has previously Information on the search history of viewers is extracted using the searched search word, the search history of other viewers for video content, etc., and related information on the extracted viewers' search history and information on the extracted viewers' search history. Recommended broadcast program information can be extracted. Thereafter, the control unit 380 of the display apparatus 100 may analyze information on the search records of viewers received from the external server 200 in real time, and display a recommended search word list 920 that can be input by the user. In this case, when the user selects and inputs one of the recommended search word List 920, the controller 380 may display a list of recommended broadcast programs (see FIGS. 8B and 9B) related to the selected search word.

In addition, in the above-described embodiment, it is assumed that the user inputs a search word through the user input unit. This is only an example, and a search word can be input through various input devices such as a voice input unit, a touch screen, and a pointing device. have.
