Next, the problem of the conventional display device 100 will be described with reference to FIG.

5 is a view for explaining a problem of a conventional display device. More specifically, FIG. 5A may be a screen displayed when the display device 100 displays an image corresponding to a signal received through the antenna cable.

5B shows a screen displayed when the display device 100 displays an image corresponding to a signal received through an external input such as a set-top box.

5A, when the display device 100 receives a signal through an antenna cable, at least one of the channel number 501, the channel name 502, and the program name 503 currently being broadcast The channel information including the above can be received together and displayed on the screen. Accordingly, in this case, the display apparatus 100 can analyze the viewing pattern of the user based on the received channel information.

5B, when the display apparatus 100 receives a signal through an external input such as a set-top box or the like, it can not receive information related to the currently broadcast channel. Accordingly, in this case, the controller 170 can not acquire information such as the channel number, the channel name, or the program name currently being broadcasted, and only the name 511 of the external input device or the type 512 of the external input, Can be displayed.

5B, when the display apparatus 100 receives a signal through an external input such as a set-top box or the like, it is necessary to provide information related to the currently viewed channel and program in order to provide a customized service to the user A method of acquiring the information is required. In particular, given the recent increase in the use of set-top boxes, the need for such a method is further demanded.

To this end, the set-top box analyzes the viewing pattern of the user to acquire viewing information, and transmits the acquired viewing information to the display device 100.

Alternatively, according to another embodiment of the present invention, the display apparatus 100 can recognize the character displayed on the image corresponding to the signal received from the set-top box, thereby obtaining the audience information.

To this end, the display device 100 may first perform character recognition on the entire displayed screen. At this time, the control section 170 does not need to detect the channel information display area in order to obtain the audience information. However, since character recognition is performed on the entire screen, it takes a long time to recognize the characters, and other characters included in the image are recognized together, making it difficult to acquire accurate viewing information. have.

Alternatively, character recognition can be performed only on the channel information display area of the screen displayed by the display device 100. [ In this case, the time required for character recognition is shortened, and it is possible to acquire more accurate viewing information by recognizing only the characters of the channel information. However, since the area in which the channel information is displayed differs for each set-top box, it is required to detect the channel information display area according to the type of the set-top box connected thereto.

Next, a method of detecting the channel information display area by the display device 100 will be described with reference to FIG.

First, the control unit 170 may connect to the set-top box through the external device interface unit 135 (S101).

In order for the control unit 170 to connect with the set-top box, the following steps may be required.

First, selecting a device to be connected may be included. Specifically, the control unit 170 may receive an instruction to select one of external devices including a set-top box, a DVD player, a home theater, and a sound bar. According to an embodiment of the present invention, the controller 170 may receive an instruction to select a set-top box from an external device list.

The method may further include selecting an external device connection method. Specifically, the control unit 170 may receive an instruction to select any one of an HDMI item, a component item, a wireless connection item, and an external input item including an external input. According to an embodiment of the present invention, the control unit 170 may receive an instruction to select an HDMI item among the device connection methods.

It may also include selecting a service brand, an installation area, or a manufacturer. Specifically, the control unit 170 may receive a command for selecting a service brand providing the broadcast service to use and a current region in which the set-top box is installed. Also, as the case may be, the control unit 170 may receive an instruction to select a maker of the set-top box.

Next, the controller 170 may transmit a signal requesting the channel information display area of the corresponding device to the server based on the display device information and the set top box information (S103).

The area in which the channel information is displayed may be different depending on the type of the display device and the type of the set-top box. Accordingly, the controller 170 can transmit a signal requesting the channel information display area to the server according to the display device information and the information of the set-top box connected to the display device.

Display device information and set-top box information may be received via HDMI-CEC (HDMI-CEC) or received via user input.

Consumer Electronics Control (CEC) is a protocol for providing a high level of control among various audio and video products in a user environment. Therefore, HDMI-CEC is a protocol for providing high-level control functions between devices connected by HDMI.

The server receiving the channel information request signal can obtain whether or not the channel information display area information in the display device is stored based on the received display device information and the set top box information. When the server stores information on the channel information display area in the display device, the server can transmit the channel information display area to the display device. In addition, if the server does not store information on the channel information display area in the display device, the server can transmit a signal including a message indicating that the information is not present to the display device.

The controller 170 may determine whether the channel information display area has been received from the server (S105). If the controller 170 does not receive the channel information display area from the server, the controller 170 may enter the integrated remote controller setting step (S107). Alternatively, if the controller 170 receives a signal including a message indicating that there is no information on the channel information display area from the server, the controller 170 may enter the integrated remote controller setting step (S107).

The integrated remote controller setting step means a step required to control a display device such as a TV and a set-top box with one remote control device 200. Accordingly, the user can control not only the display device and the set-top box but also the DVD player and the home theater with a single remote controller 200.

The control unit 170 may request a signal to press a key button provided in the remote control device 200 for setting the integrated remote control. In particular, the controller 170 may request a signal to press a channel key button or a numeric key button.

The control unit 170 may receive a key button operation command for pressing the channel key button or the numeric key button provided in the remote control device 200 from the remote control device 200 in step S109.

Next, an operation of receiving a key button operation command for pressing a channel key button or a numeric key button from the remote controller 200 will be described with reference to FIG.

7 is an example of an integrated remote controller setting screen for displaying an integrated remote controller setting in a display device according to an exemplary embodiment of the present invention.

The control unit 170 displays a request message to press the channel key button or the numeric key button provided in the remote control device 200 for setting the integrated remote control on the integrated remote control setting screen 700 as shown in FIG. .

The integrated remote controller setting screen 700 may include at least one of external device information 701, a key button command display window 702, and a preview image window 703 connected to a display device.

The external device information 701 may include a type of external device connected to the display device 100, a connection method with the external device, and information related to the external device. According to an embodiment of the present invention, as shown in FIG. 7, the display device 100 may be connected to the set-top box via HDMI, and may indicate that the LK TV brand is providing an IPTV service. However, this is merely exemplary and not limited thereto.

The key button command display window 702 may include a message to press a specific key button included in the remote controller 200 for setting the integrated remote controller. For example, the message may be a description such as "Press the number 1 button" (not shown) and may be a highlighted number 1 entry as shown in FIG.

The reason for issuing a command to press a specific key button is that the information of the device to be used must be registered in order to set the integrated remote controller. Specifically, in order to set the integrated remote controller, a code set of a device to be controlled according to the maker and model information of the device is required. However, since the manufacturers of the display device are various and the device models are various, It is difficult to set the control code set. Therefore, in order to facilitate this, an instruction is issued to press a specific key button, and the integrated remote controller can be set by recognizing the device using information received according to the command.

According to the example shown in FIG. 7, the controller 170 requests a command to press the number 1 button among the number 1 button, the channel up button, and the menu button provided in the remote controller 100.

The preview image 703 is a preview screen for displaying an image corresponding to a signal received from the remote controller 200 according to the key button command display window 702. [

Again, Fig. 6 will be described.

The control unit 170 detects a change area of the displayed image based on the key button operation command received from the remote control device 200 (S111).

The control unit 170 can detect the change area of the image after the point of time when the key button operation command is received from the remote control device 200 to detect the channel information display area.

The change area of the image may be an area generated by displaying the changed channel information before informing the user before changing the channel upon receiving the operation command for changing the channel from the remote controller 200. [

Next, the operation of detecting a change area of an image will be described with reference to Figs. 8 to 12. Fig.

FIGS. 8 to 12 are diagrams for explaining change area detection of an image after receiving a key button operation command from a remote controller according to an embodiment of the present invention.

First, the detection of a change area of an image in accordance with a numeric key button operation command will be described.

The control unit 170 may display a request message on the display unit 180 to press the number 1 button provided on the remote control device 200 as shown in FIG.

The user can see a request message to press the number 1 button in the key button command display window 702 displayed on the display unit 180 and can issue a key button operation command for pressing the number 1 button provided in the remote controller 200 have.

The controller 170 receives the key button operation command for pressing the number 1 button included in the remote controller 200, and can display the number 1 with the channel information 801 as shown in FIG.

The reason for displaying the channel information 801 is that the user confirms whether or not the command for operating one channel through the remote control device 200 matches the command received at the display device 100. [ Accordingly, when receiving the channel operation command through the other key buttons as well as the numeric 1 key button, the controller 170 can display the contents corresponding to the received key button operation command in the channel information 801. [

When the key button command is received from the remote control device 200 as described above, the content corresponding to the received key button command is displayed, thereby causing a change in the image. The control unit 170 can detect the change area of the image.

Next, after displaying the number 1 in the channel information 801, the control unit 170 can switch to the channel corresponding to the number 1. 9, the control unit 170, together with the channel number 801 including the channel number and the broadcast station name corresponding to the channel, (703).

Next, the detection of the change area of the image in accordance with the channel key button operation command will be described.

The control unit 170 may display a request message on the display unit 180 to press a channel up button included in the remote control device 200 as shown in FIG.

The user can issue a manipulation command to press the channel up button provided in the remote control device 200 by viewing a request message to press the channel up button in the key button command display window 702 displayed on the display unit 180. [

Upon receipt of the operation command for pressing the channel up button included in the remote control device 200, the controller 170 transmits the number 2 to the channel 1, as shown in FIG. 11, Information 801 can be displayed.

At this time, the control unit 170 can also detect the change area of the image in which the channel information 801 is converted from 1 to 2.

Next, the control unit 170 switches to the channel No. 2, and as shown in FIG. 12, the channel information 801 including the channel number and the broadcast station name corresponding to the channel, And can be displayed on the preview image window 703.

As described above, the control unit 170 receives the key button operation command for pressing the channel key button or the numeric key button, and detects the change area of the image, which is changed to display the channel information 801 immediately after receiving the key button operation command can do.

The controller 170 may detect the channel information display area using the size or the font size of the character. Specifically, the controller 170 receives the channel change command from the remote controller 200, detects that only the shape of the character is changed while maintaining the font body and size of the character displayed on the image, As shown in FIG.

Again, Fig. 6 will be described.

The control unit 170 stores the changed area of the detected image as the channel information display area in the storage unit 140 (S113).

Thereafter, character recognition is performed only for the stored channel information display area. A detailed description thereof will be described later.

In addition, the controller 170 may transmit the stored channel information display area to the server (S115).

The control unit 170 may transmit the channel information display area to the server together with information on the display device and information on the set-top box.

The server can store information on the received display device and information on the set-top box and corresponding channel information display area in the memory.

Through this method, the server can continuously update, store, and manage the channel information display area for each type of display device and set-top box. Accordingly, upon receipt of the request for the channel information display area, the server can transmit the channel information display area depending on whether the channel information display area is stored according to the type of the display device and the set-top box included in the received request . In this case, the operation for detecting the channel information display area as described above is not required.

Next, an operation of receiving the information from the server without detecting the channel information display area will be described with reference to Fig.

If the controller 170 receives the information on the channel information display area stored in the server from the server in step S105, the controller 170 may store information on the received channel information display area in the storage unit 140 (step S117).

The server can transmit information on the channel information display area storing the information on the display device and the set-top box to the display device.

The display device can receive the channel information display area of the display device from the server and store the received channel information in the storage part 140. [ In this case, the process of detecting the channel information display area in the integrated remote controller setting step is not required.

The control unit 170 receives an operation command from the remote control device 200 to depress a channel key button or a numeric key button provided in the remote control device 200 (S119) (S121).

The detailed description thereof is the same as that described in step S109 and step S111.

The controller 170 may determine whether the channel information display area according to the received channel information display area information matches the change area of the detected image (S123).

According to an embodiment of the present invention, the controller 170 may obtain the coincidence between the channel information display area and the change area of the detected image at a ratio of overlapping areas. Specifically, when the area of the overlapped portion of the channel information display area and the detected change area of the detected image is equal to or larger than a predetermined ratio of the area area, it can be determined that the areas coincide with each other.

Alternatively, according to another embodiment of the present invention, the controller 170 may acquire the coincidence between the channel information display area and the change area of the detected image from the scale position information. Specifically, the channel information display area and the change area of the detected image can be respectively stored as x-coordinates and y-coordinates for the entire area. For example, the channel information display area is a region including (1,1), (6,1), (1,4), (6,4) , (8,3), (2,6), and (8,6). Therefore, if there are overlapping parts in both areas stored in this manner, it can be determined that the areas match. But. The method of determining whether or not such regions are matched is illustrative, and is not limited thereto.

Next, an operation of confirming whether or not the received channel information display area coincides with the change area of the detected image will be described in detail with reference to Figs. 13 to 14. Fig.

FIGS. 13 to 14 are views for explaining an operation of checking whether a channel information display area received from a server and a change area of a detected image coincide with each other according to an embodiment of the present invention.

The channel information display area received from the server may be an area as shown in FIG. Specifically, a dotted line area 1301 located at the upper left of the entire area 1300 in which an image is displayed may be a channel information display area.

In addition, the change area of the detected image may be a dotted line area 1401 as shown in Fig. Specifically, a change in the image can be detected in the dotted line area 1401 located at the lower right of the entire area 1300 in which the image is displayed.

The dotted line areas 1301 and 1401 shown in FIGS. 13 and 14 are illustrative, and the position and size of the dotted line area may vary depending on the type of the display device and the set-top device. For example, the location of the dotted area may be located in one of the upper left, upper right, lower left, or lower right. In addition, the size of the area in which the channel information is displayed may vary according to the type of the apparatus, even though it is located at the upper left corner.

The controller 170 can determine whether the received channel information display area 1301 matches the change area 1401 of the detected image. Specifically, the control unit 170 can determine whether the positions of the two areas coincide with each other based on the scale information of the channel information display area 1301 and the change area 1401 of the image or based on the area ratio information of each area .

The controller 170 determines whether or not the channel information display area 1301 and the image change area 1401 match and that the channel information display area and the image change area do not coincide with each other. Specifically, the control unit 170 overlaps the area based on the scale information of the channel information display area 1301 and the scale information of the image change area 1401, It can be determined that the regions do not match. Alternatively, if the ratio of the full screen contrast channel information display area 1301 and the full screen contrast image change ratio 1401 are different, the controller 170 may determine that the two areas do not match.

Such a method of determining whether or not both regions are coincident is an exemplary one, and may be determined differently.

Again, Fig. 6 will be described.

If it is determined that the received channel information display area and the detected image change area do not coincide with each other (S123), the controller 170 can acquire the change area of the detected image as the channel information display area (S125).

The control unit 170 may update the channel information display area to the change area of the detected image and store the updated channel information display area in the storage unit 140 if the received channel information display area does not match the change area of the detected image.

This is because, even if the same display device and the same set-top box are used, the channel information display area can be changed as the set-top box is updated, so that the channel information display area is updated.

The controller 170 can update and transmit the stored channel information display area to the server (S127).

If the channel information display area received from the server does not match the change area of the detected image, the controller 170 may transmit a request to the server to update the channel information display area. Alternatively, the controller 170 may transmit a message to the server indicating that the channel information display area has been changed.

In addition, the controller 170 may transmit the detected change region of the image to the server so that the server can update the channel information display region.

The server may receive a request from the display device 100 to update the channel information display area. Alternatively, the server may receive a message from the display device 100 indicating that the channel information display area has been changed.

The server can receive the changed channel information display area from the display device 100. [ The server can delete the previously stored channel information display area and store the received channel information display area. Specifically, the server may update and store the previously stored channel information display area corresponding to the information of the display device and the set-top box that transmitted the channel information display area to the newly received channel information display area.

In addition, the server can confirm whether the channel information display area has been updated properly. Specifically, the server may transmit the updated channel information display area to the display device 100. [

The display device 100 determines whether the received updated channel information display area matches the change area of the detected image. If the updated channel information display area matches the change area of the detected image, the controller 170 can transmit a message to the server that the update is performed properly. Alternatively, if the received updated channel information display area and the detected change area of the detected image do not coincide with each other, the controller 170 may transmit a message to the server that the update is not performed properly.

As such, the display device 100 can send feedback to the server about the update.

According to this method, even when the position of the channel information displayed on the display device changes, it is possible to update the channel information display area without setting or manipulating that the channel information display area is changed arbitrarily.

Also, there is an effect that updating of the channel information display area according to the type of the display device and the set-top box can be automatically performed without any additional operation by the user, so that the updated channel information display area can be easily updated.

In addition, by receiving update information on the channel information display area of the server, it is confirmed whether the update has been properly performed, and it is possible to provide quick and accurate information on the channel information display area.

In addition, if the channel information display area and the changed area of the detected image coincide with each other (S123), the controller 170 can transmit the stored channel information display area to the server (S127).

The server can check whether the channel information display area is updated by determining whether the received channel information display area matches with the transmitted channel information display area.

Alternatively, according to another embodiment of the present invention, a message indicating that the received channel information display area and the detected channel information display area coincide with each other can be transmitted to the server without transmitting the stored channel information display area.

Next, a method of providing related information using the channel information display area will be described with reference to FIG.

15 is a flowchart illustrating a method of providing related information using a channel information display area according to an embodiment of the present invention.

The control unit 170 may receive an operation command from the remote control device 200 to press a channel key button or a numeric key button provided in the remote control device 200 (S201).

The user can press the channel key button or the numeric key button provided in the remote control device 200 to change the channel.

The control unit 170 can receive a channel key button for changing the channel from the remote control device 200 or an operation command for pressing the numeric key button.

After receiving the operation command from the remote control device 200, the control unit 170 recognizes characters displayed in the channel information display area (S203).

Next, a method of recognizing characters displayed in the channel information display area will be described with reference to Fig.

16 is a diagram for explaining a method of recognizing characters displayed in a channel information display area according to an embodiment of the present invention.

According to an embodiment of the present invention, the control unit 170 may perform character recognition on the entire area 1600 in which an image is displayed.

As a method of recognizing a character, it is possible to use a pattern matching technique in which a plurality of standard pattern characters prepared in advance are compared with input characters and a character most similar to the standard pattern character is selected as the corresponding character. However, Other techniques may be used.

When the control unit 170 performs character recognition on the entire area 1600 in which an image is displayed, the character displayed in the channel information display area 1601, the character displayed in the area 1 1602, It is possible to recognize all the characters displayed in the second area 1603.

However, when character recognition is performed on the entire area 1600, it may take a long time to perform character recognition. In addition, since the shapes and sizes of the characters displayed on the video are various, the possibility that the characters are misrecognized increases.

In accordance with another embodiment of the present invention, the controller 170 may perform character recognition only on the channel information display area 1601. FIG. In the case of performing character recognition only on the channel information display area 1601, the time required for character recognition may be short because the target area for character recognition is relatively narrow. In addition, since the characters displayed in the channel information display area 1601 are generally characters having a predetermined shape and size, the possibility of erroneous character recognition may be low.

The controller 170 may perform character recognition on the channel information display area 1601 to acquire channel information such as a channel number and a channel name.

15 will be described again.

The control unit 170 acquires the audience information based on the recognized character (S205).

The viewing information may represent information such as a channel preferred by the user, a program preferred by the user, a time zone in which the user mainly watches the video, and the like.

The control unit 170 can acquire the audience information in consideration of various factors such as the frequency of the characters repeatedly recognized and the time period when the characters are recognized by using the recognized characters.

The control unit 170 can receive an operation command for pressing the search key button from the remote control device 200 (S207).

The control unit 170 can receive an operation command from the remote control device 200 to depress a search key button provided in the remote control device 200. [

Alternatively, the control unit 170 may receive an operation command from the remote control device 200 to press a key button for viewing broadcast information provided in the remote control device 200.

The control unit 170 may display the related recommendation information based on the obtained audience information in response to the operation command received from the remote control device 200 (S209).

17 to 19, the operation of displaying the related recommendation information based on the obtained audience information in response to the operation command received from the remote control device 200 will be described.

17 to 19 are views for explaining an operation of displaying related recommendation information based on the obtained audience information according to an embodiment of the present invention.

As shown in Fig. 17, the control unit 170 can receive an operation command to press the search key button from the remote control device 200. [ Accordingly, the control unit 170 can display the related recommendation information 1702 together with the search window 1701. The reason for displaying the related recommendation information 1702 together with the search window 1701 is to display the information that the user can search for in order to save the user from the trouble of searching.

Accordingly, the related recommendation information 1702 may include information that can be recommended to the user based on the previously obtained audience information. For example, it may be information obtained by acquiring a program broadcast in the time zone and channel most frequently viewed by the user from the EPG, and acquiring a story, an actor, an Internet article, etc. related to the program. As another example, a user may include information related to a program that is the most preferred channel. In addition, the related recommendation information 1702 may include information that is recommended to the user in relation to the currently displayed image. For example, the control unit 170 may display information such as broadcast information, related drama, video, music, actor, or audience rating / related search word, as related recommendation information 1702 with respect to the currently displayed image.

Alternatively, as shown in FIG. 18, the control unit 170 can display the related recommendation information 1800 upon receipt of an operation command to press the channel key button from the remote control device 200. FIG. In this case, the recommendation recommendation information 1800 includes the current channel number and channel name 1801, broadcast information 1802 about the currently broadcasted program, video 1803 related to the program currently being broadcast, or information 1804 related to the next program ), And the like. Also, it is apparent that the related recommendation information 1702 as shown in Fig. 17 can be included.

19, upon receipt of an operation command to press a key button for viewing broadcast information from the remote control device 200, the control unit 170 displays EPG information 1920 on the broadcast guide screen 1900 And related recommendation information 1910 can be displayed together with the recommendation information. The related recommendation information 1910 may include an associated video 1911. The related video 1911 may include a link of the associated content.

As described above, according to the embodiment of the present invention, when the control unit 170 receives the operation command to press the key button from the remote control device 200, it can display the related recommendation information corresponding to the received operation command.

According to an embodiment of the present invention, the above-described method can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .

The above-described display device is not limited to the configuration and method of the above-described embodiments, but the embodiments may be configured such that all or some of the embodiments are selectively combined so that various modifications can be made. It is possible.
