6 is a flowchart illustrating a method of operating an image display apparatus according to an exemplary embodiment of the present invention, and FIGS. 7 to 13 are views for explaining various examples of the method of operating the image display apparatus of FIG. 7.

Referring to the drawing, first, an external input image is received from an external device (S610). The external device interface 135 of FIG. 7 receives an external input image from the external device 300. The external device 300 may be various examples such as an optical disc player such as a Blu-ray player, a set top box, a camera, and a game device. The following description focuses on the optical disc player.

When the content is played in the optical disc player 300, the played content may be input to the HDMI terminal of the external device interface unit 135.

8 illustrates that a content image 810 reproduced in the optical disc player 300 is transmitted to the image display apparatus 100.

Meanwhile, the playback content image 810 input to the external device interface unit 135 is transmitted to the image synthesizing unit 710. The image synthesizing unit 710 receives the external input image 810 from the external device interface unit 135.

Next, the OS or image is received from the server (S620). The network interface unit 130 of FIG. 7 receives an OSD or an image from the server 500 through a network.

For example, when there is a home screen display input of the image display apparatus 100, the image display apparatus 100 may transmit an OSD or graphic image transmission request related to the home screen to the server 500. Accordingly, the server 500 generates an OSD or graphic image related to the home screen in the graphic processing unit 750, and displays an image of the OSD or graphic image related to the home screen through the network interface unit 730. To the device 100.

8 illustrates that the OS 820 related to the home screen generated by the server 500 is transmitted to the image display apparatus 100.

The network interface unit 130 of the image display apparatus 100 receives an OSD or graphic image 820 associated with the generated home screen, transmits the received OS or graphic image 820 to the image synthesizing unit 710, and then, the image synthesizing unit ( 710 receives an OSD or graphical image 820 associated with the home screen.

Next, it is determined whether a broadcast image is received by the image display apparatus 100 (S625). If a broadcast image is not received, step S630 may be performed. When the broadcast video is received, operation S635 may be performed.

In operation S630, the image synthesis unit 710 synthesizes the received OSD or image and the received external input image in operation S630. The display 180 displays the synthesized video (S640).

The image synthesizer 710 synthesizes the received external input image 810 and the OSD 820 related to the received home screen. To this end, scaling of the received external input image 810 may be performed. In FIG. 8, it can be seen that the size of the external input image 815 in the home screen displayed in the display 180 is smaller than that of the external input image 810 input from the optical disc player 300.

The image synthesizing unit 710 may arrange the positions of the scaled external input image 815 according to the home screen setting. In FIG. 8, the scaled external input image 815 is disposed on the upper left portion of the display 180.

In this way, the video display device 100 synthesizes and displays the received external device input video and the received OSD or image, thereby efficiently managing resources between the video display device and the server.

In operation S635, the image synthesizer 710 synthesizes the received OSD or image and the received broadcast image in operation S630. The display 180 displays the synthesized video (S640).

The broadcast signal may be received through the broadcast receiver 105, for example, the tuner 110, the demodulator 120, or the like in the image display apparatus 100. The received broadcast signal is signal processed through demultiplexing, and the like, and the broadcast image of which the signal is processed may be input to the image synthesizer 710.

FIG. 11 illustrates a broadcast image 1110 received by the video display device 100, in particular, by the broadcast receiver 105.

The image synthesizer 710 synthesizes the received broadcast image 1110 and the OSD 820 related to the received home screen. To this end, scaling of the received broadcast image 1110 may be performed. In FIG. 11, it can be seen that the size of the broadcast video 1115 in the home screen displayed in the display 180 is smaller than the broadcast video 1110 received by the broadcast receiver 105.

The image synthesizing unit 710 may arrange the positions of the scaled broadcast image 1115 according to the home screen setting. In FIG. 11, the scaled broadcast image 1115 is disposed on the upper left portion of the display 180.

In this way, the video display device 100 synthesizes and displays the received broadcast video and the received OSD or image, thereby efficiently managing resources between the video display device 100 and the server 500. do.

As shown in FIG. 8, the image synthesis in the image display apparatus 100 is performed by using the OS 820 related to the home screen generated by the server 500 and the external input image 810 received from the optical disc player 300. In operation 710, when the OS 820 and the external input image 810 are synthesized, the home screen 900 as illustrated in FIG. 9 may be displayed on the display 180 of the image display apparatus 100. .

9 illustrates that a home screen is displayed on the display 180 of the image display apparatus.

The home screen 900 of FIG. 9 is an initial screen when the power is on or in the standby mode, or is provided in the local key (not shown) or the remote controller 200. It may be set as a basic screen by the operation of a home key (for example, a 'menu' button).

In order to implement such a home screen, the smart system platform may be mounted in the processor 740 or a storage unit (not shown) in the server 500.

For example, the smart system platform may include an OS kernel, a library on the OAS kernel, a framework, and an application layer. Under this smart system platform, the application can be freely downloaded, installed, executed, deleted, and the like.

The home screen 900 of FIG. 9 broadly lists items from a live image area 910 displaying a live image 815, from various sources (eg, content providers or applications such as CPs). The card object area 920 including the card objects 921 and 1222 to be displayed separately, and the application menu area 930 including a shortcut menu of the application item.

In the drawing, the application menu area 930 is displayed at the bottom of the screen. In addition, the login item and the exit item are further displayed.

In this case, the live image area 910 and the application menu area 930 may be fixedly displayed items or objects therein.

Meanwhile, the card object area 920 may be displayed by moving or replacing the card objects 921 and 922 therein. Alternatively, each item (eg, an item “yakoo”) in the card objects 921 and 922 may be displayed by being moved or replaced.

Meanwhile, in the drawing, the scaled external image 815 in which the external input image input from the external device is scaled is displayed in the live image area 910.

Meanwhile, as shown in FIG. 9, when the location of the pointer 905 is in the live image 915 while the home screen is displayed on the display 180, an arrow-shaped pointer 905 may be displayed.

For example, when a pointing signal (motion information, etc.) of the remote control apparatus 200 is input through the user input interface unit 150 of the image display apparatus 100 of FIG. 7, the user input interface unit 150 is input. Alternatively, the processor 330 may extract pointer coordinate information of the remote controller based on the pointing signal. The extracted pointer coordinate information may be transmitted to the server 500 through the network interface 130.

The server 500 may generate a pointer image together when generating an OSD or an image related to a home screen in the graphic processor 750 based on the received pointer coordinate information. Accordingly, as illustrated in FIG. 9, the pointer image 905 may be generated in the external image 815.

As another example, when a pointing signal (movement information, etc.) of the remote control apparatus 200 is input through the user input interface unit 150 in the image display apparatus 100 of FIG. 7, the processor 330 may indicate the pointing signal. Can be transmitted to the server 500 as it is.

The processor 740 of the server 500 may calculate coordinate information based on the received pointing signal. The graphic processor 750 may also generate a pointer image when generating an OSD or an image related to a home screen. Accordingly, as illustrated in FIG. 9, the pointer image 905 may be generated in the external image 815.

On the other hand, the image synthesizing unit 710 in the image display apparatus 100 has the priority of the pointer image 905 as the highest priority, so that when the image is synthesized, the pointer image is superimposed on another image or the OSD image. .

On the other hand, when the application card object 922 is selected by using the pointer 905 corresponding to the movement of the remote controller 200, the card object name 923 in the application card object 922 is selected. In this case, an app store screen (not shown) may be displayed.

Meanwhile, an app store screen (not shown) may also be generated in the server 500.

FIG. 10 illustrates that when the camera 301 is used as an external device, the user image 1010 captured by the camera 301 and another user image 1020 are transmitted from the server 500 to the image display device. To illustrate.

The other user image 1020 may be an image of a user of another image display apparatus remotely connected to the image display apparatus 100 through a network.

When the video call function of the video display device 100 is activated, the video display device 100, as shown in the figure, the user image 1010 taken by the camera 301 and another user image from the server 500 1020 may be received.

The image synthesizer 710 synthesizes the received external input image 1010 and another user image 1020 received from the server 500. To this end, scaling of another user image 1020 received from the server 500 may be performed. In FIG. 20, it can be seen that the size of the other user image 1036 in the video call screen 1030 displayed in the display 180 is smaller than that of the other user image 1020 input from the server 500.

Meanwhile, the video synthesizing unit 710 may arrange the positions of other scaled user images 1036 according to activation of the video call function. 20 illustrates placing another scaled user image 1036 in the lower left portion of the display 180.

As such, the image display apparatus 100 efficiently displays resources between the image display apparatus 100 and the server 500 by synthesizing and displaying the external apparatus input image received from the external apparatus and the image received from the server. It can be managed.

Meanwhile, as shown in FIG. 11, the OSD 820 associated with the home screen generated by the server 500 and the broadcast image 1110 received by the image display apparatus 100 are used to operate in the image display apparatus 100. When the image synthesizer 710 synthesizes the OS 820 and the broadcast image 1110, the home screen 1200 as shown in FIG. 12 may be displayed on the display 180 of the image display apparatus 100. have.

12 illustrates that a home screen is displayed on the display 180 of the image display apparatus.

The home screen 1200 of FIG. 12 is similar to the home screen of FIG. 9, except that the broadcast screen 1115 is displayed in the live video area 1110 instead of the external input video 815. Accordingly, broadcast video information is displayed in the broadcast video 1115.

Meanwhile, as shown in FIG. 12, when the location of the pointer 1205 is in the broadcast image 1115 while the home screen is displayed on the display 180, an arrow-shaped pointer 1205 may be displayed.

For example, when a pointing signal (motion information, etc.) of the remote control apparatus 200 is input through the user input interface unit 150 of the image display apparatus 100 of FIG. 7, the user input interface unit 150 is input. Alternatively, the processor 330 may extract pointer coordinate information of the remote controller based on the pointing signal. The extracted pointer coordinate information may be transmitted to the server 500 through the network interface 130.

The server 500 may generate a pointer image together when generating an OSD or an image related to a home screen in the graphic processor 750 based on the received pointer coordinate information. Accordingly, as illustrated in FIG. 11, the pointer image 1205 may be generated in the broadcast video 1115.

As another example, when a pointing signal (movement information, etc.) of the remote control apparatus 200 is input through the user input interface unit 150 in the image display apparatus 100 of FIG. 7, the processor 330 may indicate the pointing signal. Can be transmitted to the server 500 as it is.

The processor 740 of the server 500 may calculate coordinate information based on the received pointing signal. The graphic processor 750 may also generate a pointer image when generating an OSD or an image related to a home screen. Accordingly, as illustrated in FIG. 11, the pointer image 1205 may be generated in the broadcast image 1115.

On the other hand, the image synthesizing unit 710 in the image display apparatus 100 has the priority of the pointer image 1205 as the highest priority, so that when the image is synthesized, the pointer image is superimposed on another image or the OSD image. .

Meanwhile, FIG. 13 illustrates that one server 500 transmits an OSD or an image to the plurality of image display apparatuses 100a and 100b.

The video display device system 50 according to an exemplary embodiment of the present invention may control the video display devices 100a and 100b by using the server 50.

In detail, when the server 500 receives an OSD or image transmission request from the first image display apparatus 100a, the server 500 generates the corresponding OSD or image 1310 in response to the request. . The generated OS or image 1310 is transmitted to the first image display apparatus 100a through the network interface unit 730.

On the other hand, when the server 500 receives an OSD or image transmission request from the second image display apparatus 100b at the same time, the graphic processing unit 750 generates the corresponding OSD or image 1320 according to the request. do. The generated OSD or image 1320 is transmitted to the second image display apparatus 100b through the network interface unit 730.

As such, when receiving the OSD or image transmission request from the plurality of image display apparatuses 100a and 100b, respectively, the graphic processing unit 750 in the server 500 may execute the corresponding OSD or image in parallel, respectively. By creating the 1310, 1320, it is possible to perform data processing quickly.

14 is a flowchart illustrating a method of operating a server according to an embodiment of the present invention.

Referring to the drawing, first, an OSD or an image transmission request is received from an image display apparatus (S1410).

For example, when there is a home screen display input, the video display device 100 may transmit a home screen-related OSD or image transmission request to the server 500.

As another example, when the video call function is activated, the video display device 100 may transmit another user captured image transmission request to the server 500.

The network interface unit 730 in the server 500 may receive this request and forward it to the processor 740.

Next, according to the request, the corresponding OSD or image is generated (S1420).

For example, the graphic processor 740 in the server 500 generates a corresponding home screen OSD or image according to the home screen OSD or image transmission request.

As another example, the network interface unit 730 in the server 500 may receive another user captured image from another image display device through a network according to another user captured image transmission request.

Next, the generated OS or image is transmitted to the image display apparatus (S1430).

The network interface unit 730 in the server 500 may transmit the generated home screen-related OSD or image to the image display apparatus 100 or may transmit another received user captured image to the image display apparatus.

The server 500 may include an external device interface unit (not shown), through which an external input image may be received from the external device 300.

FIG. 16 illustrates that the content image 810 reproduced in the optical disc player 300 is transmitted to the server 500. Similar to FIG. 8, the difference is that the reproduced content image 810 is transmitted to the reproduced server 500 instead of the image display device 100.

17 illustrates that the user image 1010 captured by the camera is transmitted to the server 500. Although similar to FIG. 10, there is a difference in that the captured user image 1010 is transmitted to the reproduced server 500 instead of the image display apparatus 100.

In operation S1510, an OSD or image transmission request is received from the image display apparatus 100. In operation S1520, the corresponding OSD or image is generated according to the request. In operation S1525, the OSD or the image and the external input image are synthesized.

For example, when there is a home screen display input, the video display device 100 may transmit a home screen-related OSD or image transmission request to the server 500.

According to the home screen display input, the server 500 generates an OSD or an image 820 related to the home screen. The image synthesizer (not shown) in the server 500 synthesizes the generated OSD or image 820 and the external input image 810.
