Thereby, the selected area in the display 180 corresponding to the pointer 205 can be zoomed in and displayed. Conversely, when the user moves the remote control device 200 close to the display 180, the selection area within the display 180 corresponding to the pointer 205 may be zoomed out and zoomed out. On the other hand, when the remote control device 200 moves away from the display 180, the selection area is zoomed out, and when the remote control device 200 approaches the display 180, the selection area may be zoomed in.

On the other hand, when the specific button in the remote control device 200 is pressed, it is possible to exclude recognizing the up, down, left, and right movement. That is, when the remote control apparatus 200 moves away from or approaches the display 180, it is not recognized that the up, down, left, and right movements are recognized, and only the forward and backward movements are recognized. Only the pointer 205 is moved in accordance with the upward, downward, leftward, and rightward movement of the remote control device 200 in a state where the specific button in the remote control device 200 is not pressed.

On the other hand, the moving speed and moving direction of the pointer 205 may correspond to the moving speed and moving direction of the remote control device 200.

That is, when the OK key 291 is pressed, it is used as a menu or item selection. When the OK key 291 is scrolled up and down, a display screen scrolling or a list page switching can be performed.

Specifically, when an image larger than the size of the display is displayed on the display unit 180 and the OK key 291 is scrolled to search for the corresponding image, the image area that is not currently displayed on the display is displayed on the display. As another example, when the list page is displayed on the display unit 180, the previous page or the next page of the current page can be displayed by scrolling the OK key 291. [

This scroll function may be provided with a separate key other than the confirmation key 291. [

On the other hand, the four directional keys 293 can be arranged in four directions in the circular type, as shown in the figure, up, down, left, and right keys.

FIG. 6 is a flowchart illustrating an operation method of an image display apparatus according to an embodiment of the present invention, and FIGS. 7 to 14 are diagrams referred to explain the operation method of FIG.

First, an operation method of an image display apparatus according to an embodiment of the present invention receives electronic program guide (EPG) information (S610)

Such an electronic program guide (EPG) is a kind of data broadcasting service that allows a user to refer to a program list of a broadcasting station or content providers through a data broadcasting.

That is, the user can obtain additional information such as information on the program, performer information, shooting location information, PPL (product in place) product information, background music, travel goods, multimedia product information, etc. while watching TV or the like.

FIG. 7A shows an example of a typical EPG screen, and FIG. 7B shows an example of a detailed view screen.

Referring to FIG. 7, if an EPG view is selected from an existing TV, only the EPG data 710 shown in FIG. 7A is displayed, and even if a detailed view of a predetermined program is selected, only basic information supplied by a content provider is provided . Therefore, in many cases, the details related to the program such as the previous program information, planning intention, broadcast time, performer information, and the like should be separately retrieved.

On the other hand, a smart TV that can use the Internet network has adopted a method of inputting a search word using a web search engine and displaying the search result as it is.

Therefore, in consideration of the case where a search is performed while watching a TV, an optimal search result related to the content being watched can not be provided. In addition, the search result is complicated, and it is inconvenient to perform the search again in the search result in order to obtain the desired search result.

On the other hand, when a search is performed while using a broadcast program or other contents, and when a search is performed on the Internet without watching a TV, the search result desired by the user may be different.

Accordingly, it is an object of the present invention to provide an image display apparatus and an operation method thereof, which can improve the user's convenience by providing search results optimized for search during content use.

Meanwhile, the image display apparatus 100 can receive electronic program guide (EPG) information through the broadcast receiving unit 105, the network interface unit 130, and the like.

For example, when a broadcast signal is received by the broadcast receiver 105, particularly the tuner 110, the demultiplexer 310 demultiplexes the audio signal, video signal, and PSIP data from the incoming broadcast signal have.

The separated PSIP data is processed to obtain the PSAT data such as system time table (STT), master guide table (MGT), virtual channel table (VCT), rating region table (RRT), event text table (EIT) Information can be stored in the storage unit 140, and basic keywords can be extracted from the information.

Meanwhile, the image display apparatus 100 according to the embodiment of the present invention generates a search term based on the received electronic program guide information (S620), and performs search based on the search term and a predetermined category (S630)

In the keyword generating step S620, the controller 170 may generate the keyword based on the basic information included in the electronic program guide. That is, a keyword may be extracted from the basic information included in the electronic program guide, and the keyword may be combined to generate the search term.

In addition, the predetermined category may be used as one of the keywords.

Here, the basic information included in the electronic program guide may be basic information supplied from a content provider or an EPG provider, for example, information shown in FIGS. 7A and 7B.

The keyword may be extracted from all the text information included in the EPG information such as program genre, program description, and the like, as well as the program title included in the EPG information.

On the other hand, a search category can be set in advance by classifying the types of search results, and a predetermined category can be used for keyword generation.

For example, the category may include categories of programs related to the broadcast information such as previous program information, planning intention, broadcast time, program related information category including the broadcast information, storyline information, brand name, lowest price, manufacturer, A location information category including travel information, transportation information, and the like may be set.

In addition, information that a viewer is wondering while watching a program is information related to a program currently being used. Therefore, the category may vary depending on the genre and other attributes of the program.

 For example, as a basic category, videos, images, personal information, places, and related search words can be set as categories. When a program being watched when a user requests detailed information viewing is a drama, ) Can be added. Category [1]: Image, category [2]: Person (performer), category [3]: Place sponsorship / location, category [4]: Related search term) , The category can be dynamically configured considering the properties of the program,

If one of the search word generation step (S620) and the search step (S630) is examined in detail, keywords such as title, main character, summary information, and the like can be extracted for at least some programs in the EPG.

For example, in the case of a music program, the keywords may include broadcast time, title, cast, song information and the like. In the case of the drama program, keywords may be extracted during broadcast, title, cast,

Thereafter, a search term is generated based on the extracted keyword. A search word can be generated by combining keywords extracted for every program stored in the EPG. For example, you can create a query with 'Program Title + Performer Name'.

On the other hand, a keyword can be used to generate a keyword. That is, the keyword may be one of a plurality of search words, or a combination of a plurality of keywords may be a search word.

Thereafter, it is possible to perform a search for each category based on the search term. Category [2] performs image search using the search term " program title ", while category [1] Category [3] can be used to search for "program title" as a search term, location support / location search, and category [4] as a search term for "program title" have. Although only one example of searching with one keyword is described here, it will be clear that a plurality of keywords can be searched as described above.

Meanwhile, the search may be performed using the Internet through which the video display device 100 is connected.

Alternatively, the search step S630 may include transmitting the keyword to the search server and receiving the search result.

The search server may be a commercial search engine such as provided on the Internet or a specialized search engine constructed to search professionally for broadcast information. In this case, the image display apparatus 100 can transmit the generated keyword and category information to the predetermined search server and receive the search result from the search server.

Meanwhile, the category may be added or modified through updating of the image display device, or may be set to a setting input by the user's own selection.

Alternatively, the frequency of use of the search results for each user may be utilized to delete the category that is not used well or to change the category lower than the frequently used category. That is, the category may be set based on the user's use history.

Meanwhile, an operation method of an image display apparatus according to an exemplary embodiment of the present invention may include the steps of: before the search word generation step (S620) or before the search step (S630), when the program end time of the electronic program guide information is after the current time And extracting information relating to the information.

That is, the present invention is for providing information optimized for a program being viewed by a user, and may not perform a search for a program that has already been terminated.

In addition, the search word generating step (S620) and the searching step (S630) may be performed automatically before the user inputs the detailed program information.

According to an embodiment of the present invention, pre-searched information is pre-searched using EPG data and category information, and the pre-searched information is stored in a database for each category. By pressing the OK key or the detailed information key, information can be retrieved and displayed from the database already retrieved and stored. Therefore, since the present invention uses pre-searched data, it is possible to provide relevant details without a search delay time.

Meanwhile, the search result by the search can be stored in the storage unit 140 (S640)

Such information may be stored in a single table or a plurality of tables, or may be stored in various ways such as a relational database structure, a tree structure, a linked-list, and the like.

Meanwhile, the search results may be classified and stored according to the categories, or may be stored for each broadcast channel. In addition, the search result may be stored and managed by linking the category or the broadcast channel in a hierarchical structure.

The present invention can be constructed with a relational database in order to store channel information related thereto in addition to the EPG database. That is, the retrieved result can be stored in each channel by program for each category.

On the other hand, when new EPG information is received and parsed, the PID values are compared, and if there is an added program, the above steps can be repeated to update the new information to the database.

8, a predetermined broadcast program 810 is displayed on the display 180, and a program detailed information view input, for example, an OK (OK) or detailed information key included in the remote control device is displayed (S660), a detailed information image including search results corresponding to the displayed program is displayed in the stored search results (S670)
