The processor 330 may control overall operations in the image display apparatus 100 or the controller 170. For example, the processor 330 may control the tuner 110 to control tuning of an RF broadcast corresponding to a channel selected by a user or a previously stored channel.
In addition, the processor 330 may control the image display apparatus 100 by a user command or an internal program input through the user input interface unit 150.
In addition, the processor 330 may perform data transmission control with the network interface unit 135 or the external device interface unit 130.
The processor 330 may control operations of the demultiplexing unit 310, the image processing unit 320, the OSD generating unit 340, and the like in the controller 170.
Meanwhile, in accordance with an embodiment of the present invention, when the power is turned on, the processor 330 controls to call the fixed boot image stored in the nonvolatile memory for displaying the home screen. Here, the nonvolatile memory may be the storage 140. Then, it controls to call the dynamic boot image from the network server 220, which is received through the network interface unit 130. Then, the fixed boot image and the dynamic boot image are combined to generate the final boot image. And, based on the generated final boot image, the control to display the home screen on the display 180.
In particular, when the power is turned on for the first time, since there is no dynamic boot image previously stored in the network server 220, the processor 330 generates a home screen by using the fixed boot image stored in the nonvolatile memory, and displays the display ( 180) to display.
Meanwhile, when the power is turned on, the processor 330 controls to display a user selection object for selecting a user, and controls the network interface 130 to receive a dynamic boot image for the selected user. . As a result, the processor 330 controls the generation of the final boot image and the home screen based on the same by using the operation boot image and the fixed boot image of the user.
Meanwhile, in relation to an embodiment of the present invention, when the power is turned off, the processor 330 calls the final boot image based on the last home screen displayed when the power is turned off. Then, it controls to call the fixed boot image stored in the nonvolatile memory. Here, the nonvolatile memory may be the storage 140. Then, the dynamic boot image is extracted using the final boot image and the fixed boot image. Then, the extracted dynamic boot image is controlled to be transmitted to the network server 220 through the network interface unit 130. At this time, when the power is off, the extracted dynamic boot image may be a dynamic boot image for each user. The dynamic boot image for each user may be transmitted to the network server 220, respectively.
The OSD generator 340 generates an OSD signal according to a user input or itself.

The generated OSD signal may include various data such as a user interface screen, various menu screens, widgets, and icons of the image display apparatus 100.
For example, the OSD generator 340 may generate a signal for displaying broadcast information based on subtitles or EPGs of a broadcast image.
The mixer 350 may mix the OSD signal generated by the OSD generator 340 and the decoded image signal processed by the image processor 220. The mixed signal is provided to the formatter 360. Since the decoded broadcast video signal or the external input signal and the OSD signal are mixed, the OSD may be overlaid and displayed on the broadcast video or the external input video.
The frame rate converter (FRC) 355 may convert the frame rate of the input video. On the other hand, the frame rate converter 350 can output the data as it is without additional frame rate conversion.
The formatter 360 receives the output signal of the frame rate converter 355 and changes the format of the signal to be suitable for the display 180 and outputs the signal. For example, the R, G, B data signals may be output, and the R, G, B data signals may be output as low voltage differential signaling (LVDS) or mini-LVDS.
The formatter 360 may change the format of the 3D video signal or convert the 2D video into a 3D video.
Although not shown in the figure, a 3D processor (not shown) for processing a 3D effect signal may be further disposed after the formatter 360. The 3D processor (not shown) may process brightness, tint, and color adjustment of an image signal to improve 3D effects. For example, signal processing may be performed to sharpen the near distance and blur the far distance. Meanwhile, the functions of the 3D processor may be merged into the formatter 360 or merged into the image processor 320.
The voice processing unit (not shown) in the controller 170 may perform voice processing of the demultiplexed voice signal. To this end, the voice processing unit (not shown) may include various decoders.
Also, the voice processing unit (not shown) in the controller 170 may process a base, a treble, a volume control, and the like.
The data processor (not shown) in the controller 170 may perform data processing of the demultiplexed data signal. For example, when the demultiplexed data signal is an encoded data signal, it may be decoded. The encoded data signal may be EPG (Electronic Progtam Guide) information including broadcast information such as a start time and an end time of a broadcast program broadcasted in each channel.
Meanwhile, a block diagram of the controller 170 shown in FIG. 5 is a block diagram for an embodiment of the present invention. Each component of the block diagram may be integrated, added, or omitted according to the specification of the controller 170 that is actually implemented.
In particular, the frame rate converter 350 and the formatter 360 are not provided in the controller 170, but may be provided separately.

The platform of FIGS. 6A and 6B described above may be used in a variety of electronic devices as well as an image display device.
Meanwhile, the platform of FIGS. 6A and 6B may be loaded in the storage 140 or the controller 170 or a separate processor (not shown).
7 is a flowchart illustrating a method of operating an image display apparatus according to an exemplary embodiment of the present invention, and FIGS. 8 to 14C are views referred to for describing various examples of the method of operating the image display apparatus of FIG. 7.
Referring to the drawings, first, it is determined whether the power is on (S1310). For example, when the power key of the local key (not shown) of the image display apparatus 100 or the power key of the remote control apparatus 200 operates, the power-on signal passes through the user input interface unit 150. It may be delivered to the controller 170. In more detail, it may be delivered to the processor 330 in the control unit 170.
When the power is turned on, it is determined whether the power is turned on for the first time (S1315). When the initial power is turned on, the first step S340 or less is performed.
The processor 330 may count each time the power is turned on, and determine whether the power is turned on for the first time.
On the other hand, when the power is not turned on for the first time, the fixed boot image previously stored in the nonvolatile memory is called (S1320). In operation S1325, the dynamic boot image is stored in the network server.
The processor 330 may execute a boot loader when the power is turned on. Such a boot loader may be stored in the nonvolatile memory 1410. The processor 330 may call the boot loader to execute the boot loader.
The boot loader may perform initialization of various hardware such as initialization of volatile memory. After the booting process of the boot loader is completed, the following steps may be performed.
When power is turned on instead of initially powered on, the processor 330 calls a fixed boot image stored in the nonvolatile memory 1410. The processor 330 controls to receive the dynamic boot image stored in the network server 220 through the network interface unit 135 and calls the received dynamic boot image.
The dynamic boot image received from the network server 220 may correspond to an image excluding the fixed boot image on the final home screen displayed at power off before powering on.
In this case, when the fixed boot image is called first, the fixed boot image may be temporarily stored in the volatile memory 1420. Of course the reverse is also possible.
On the other hand, when the network condition is unstable, that is, when the dynamic boot image cannot be received, only the fixed boot image may be called. In this case, similarly to the case where the power is turned on for the first time, steps 1340 or less may be performed.
Next, the final boot image is generated by combining the fixed boot image and the dynamic boot image (S1330).
When the fixed boot image and the dynamic boot image are called, the processor 330 combines them to generate a final boot image. For example, if a fixed boot image is stored in the volatile memory 1420, it is called back to the processor 330 and, in combination with the dynamic boot image, creates a final boot image.
In this case, the dynamic boot image may include information indicating the location of the dynamic boot image and information indicating the content of the dynamic boot image, and the processor 330 may use the location information and the content information of the dynamic boot image. Can be combined with a fixed boot image.
Meanwhile, the generated final boot image may be stored in the volatile memory 1420.
Next, the home screen is displayed based on the generated final boot image (S1335).
The final boot image generated by the processor 330 may be input to the OSD generator 340. On the other hand, the image processor 320 may perform signal processing (decoding, scaling, etc.) on the broadcast video. The mixer 350 may generate a home screen as illustrated in FIG. 9 or 10 by mixing the broadcast image processed with the final boot image.
In addition, the home screen generated by the mixer 350 may be displayed on the display 180.
On the other hand, the home screen displayed on the display may be the same as the last home screen displayed at the time of power off before power on. As described above, when the dynamic boot image stored in the network server corresponds to the final home screen displayed when the power is turned off, when the power is turned on again, the same home screen as the previous final home screen is displayed.
As such, the home screen is displayed by quickly booting by displaying the home screen based on the fixed boot image stored in the nonvolatile memory 1410 and the final boot image generated by using the dynamic boot image stored in the network server 220. The display becomes possible.
On the other hand, since the home screen displayed when the power is turned on is the same as the final home screen when the power is turned off, the user can watch the home screen continuously, thereby increasing user convenience.
Meanwhile, in operation S1315, when the first power-on is turned on, the fixed boot image previously stored in the nonvolatile memory is called in operation S1340. Then, the home screen is displayed based on the fixed boot image (S1345).
When initially powered on, the processor 330 calls a fixed boot image stored in the nonvolatile memory 1410.
When the call of the fixed boot image is completed, the processor 330 generates a final boot image by using only the fixed boot image.
Meanwhile, the generated final boot image may be stored in the volatile memory 1420.
Hereinafter, various examples of the operating method of FIG. 7 will be described with reference to FIGS. 9 to 14C.
9 illustrates that a home screen is displayed on the display 180 of the image display apparatus.
The home screen 1500 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. The home screen may be set as a default screen by an 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 on the controller 170, the storage 150, or a separate processor.
For example, the smart system platform may include an OS kernel, a library on the OAS kernel, a framework, and an application layer. Meanwhile, the smart system platform and the legacy system platform may be separated. Under this smart system platform, the application can be freely downloaded, installed, executed, deleted, and the like.
The home screen 1500 of FIG. 9 broadly displays, by list, items from a broadcast video area 1510 displaying a broadcast video 1501, and from various sources (e.g., content providers or applications such as CP). A card object area 1520 including card objects 1521 and 1522, and an application menu area 1530 including a shortcut menu of application items.
In the drawing, the application menu area 1530 is displayed at the bottom of the screen. In addition, the login item and the exit item are further displayed.
In this case, the broadcast image region 1510 and the application menu region 1530 may be fixedly displayed with items or objects therein.
The card object area 1520 may be displayed by moving or replacing the card objects 1521 and 1522 therein. Alternatively, each item in the card objects 1521 and 1522 (eg, an item “yakoo”) may be displayed by being moved or replaced.
Meanwhile, as shown in FIG. 9, when the home screen is displayed on the display 180, when the location of the pointer 1505 is in the broadcast image 1501, an arrow-shaped pointer 1505 may be displayed.
On the other hand, when the application card object 1522 is selected using the pointer 1505 corresponding to the movement of the remote controller 200, the card object name 1523 in the application card object 1522 is selected. In this case, as shown in FIG. 10, the app store screen 1600 may be displayed.
10 illustrates an example of an app store screen 1600 which is a kind of home screen.
Referring to the drawings in detail, as shown in FIG. 10, the app store screen 1600 may display a first area 1610 on which a broadcast image is displayed, a second area 1620 on which a tab menu is displayed, and a plurality of card objects. The third region 1630, and the fourth region 1650 on which menu items are displayed. The tab menu may include a category item for classifying a plurality of applications.
Through the tab menu, applications are categorized into categories, for example, as shown in FIG. 10, and provided to the user by categorizing the category items most relevant to the application such as games, news, sports, and the like. It can help you figure it out.
In addition, since the user can access the app store while watching the broadcast video 1611, the application to be installed can be searched without missing the content to be watched.
On the other hand, when a category item of one of the tab menus (All, Entertain, Game, ...) is selected, a plurality of card objects 1631, 1633, and 1635 are placed in the third area 1630 of the display 180. In addition, icons of applications included in the selected tab menu may be classified and displayed on the plurality of card objects 1631, 1633, and 1635.
In other words, the applications included in the selected category item are reclassified according to a predetermined criterion, and displayed according to a card object so that the user can easily identify the applications.
Icons of applications included in the selected tab menu may be reclassified and displayed on the corresponding card object.
FIG. 10 illustrates an example in which a category item 'All' 1621 including all applications is selected. As shown in FIG. 10, the selected category item 1621 may be displayed differently from other category items 1622 in a display state such as color and size.
Meanwhile, selection of one of the tab menus is possible not only when an item is selected by the user, but also by setting.
For example, when the default setting is set to the 'All' category item, when accessing the App Store, the application card objects included in the 'All' category item are automatically displayed on the screen as shown in FIG. 10. Can be.
Meanwhile, at least one of the plurality of card objects may further include a menu object 1640 for viewing another application. The menu object 1640 may be represented as a graphic object in various ways. For example, as shown in FIG. 10, when the menu object 1640 is displayed in a direction, and there is an input corresponding to the menu object 1640, the icon corresponding to the application in the direction indicated by the menu object 1640. Can be displayed.
A menu object may be selected using a pointer 1690 displayed in response to input of a direction key of the remote controller or movement of the remote controller, and then icons corresponding to applications included in the corresponding card object are displayed.
In addition, the fourth region 1650 of the display 180 may display menu items including separate menus such as a search menu, a view menu of an application, and an exit menu.
For example, when the exit menu of the app store is selected, the home screen 1500 of FIG. 9 may be displayed again.
11 through 12 illustrate generating a final boot image by using a fixed boot image and a dynamic boot image.
Referring to the drawing, a region of the home screen 1500 of FIG. 9 except for the broadcast video region 1510 may correspond to the fixed boot image 1710.
Meanwhile, the screen may be switched by the user's input or the like to display the home screen 1600 of FIG. 10. In this case, when the power is turned off, the dynamic boot image may be stored in the network server 220.
The dynamic boot image 1720 includes a second region 1620 in which the tab menu of FIG. 10 is displayed, a partial region of the third region 1630 in which a plurality of card objects are displayed, and menu items, as compared to FIG. 9. It may correspond to the fourth region 1650 to be displayed.
In this case, the dynamic boot image 1720 stored in the network server 220 may include information indicating the location of the dynamic boot image and information indicating the content of the dynamic boot image. Furthermore, the information may further include user information.
In the drawing, the dynamic boot image 1720 is shown to include a first dynamic boot image 1725 and a second dynamic boot image 1728.
The first dynamic boot image 1725 and the second dynamic boot image 1728 may be images spaced apart from each other. Accordingly, the header 1726 of the first dynamic boot image 1725 may include information indicating the location of the first dynamic boot image 1725, and the data 1725 of the first dynamic boot image 1725 may be included in the header 1726. It may include information indicating the content of the first dynamic boot image 1725.
At power-on, the processor 330 calls the fixed boot image 1710 associated with the home screen 1500 of FIG. 9 from the nonvolatile memory 1410, and the home screen 1600 of FIG. 10 from the network server 220. Call the dynamic boot image 1720 and combine them to create the final boot image 1730. In particular, the final boot image 1730 may be generated using location information and content information of the dynamic boot image 1720.
13A to 13D illustrate a process of displaying a home screen on a display when the power is turned off and the power is turned on.
FIG. 13A illustrates that a basic home screen 1500 is displayed as shown in FIG. 9. The basic home screen 1500 may be divided into a broadcast image area, a card object area, and an application area as shown in the drawing.
Next, FIG. 13B illustrates that the app store screen 1600 is displayed as shown in FIG. 10. When an application card object in the card object area of FIG. 13A is selected, the app store screen 1600 may be displayed as shown in the figure.
Next, FIG. 13C illustrates that the power is turned off, so that no image is displayed on the display 180. When the power is turned off, as described above, the processor 330 is based on the home screen 1600 and the basic home screen 1500 to be finally displayed, specifically, the home screen 1600 and the fixed boot image to be finally displayed. Based on 1710, the dynamic boot image 1720 is extracted, and the dynamic boot image 1720 is transmitted to the network server 220.
Next, FIG. 13D illustrates that the same home screen 1600 is displayed as the home screen that is finally displayed when the power is turned on again. That is, the app store screen 1600 is displayed.
To this end, the image display apparatus 100 combines the fixed boot image 1710 from the nonvolatile memory 1410 and the dynamic boot image 1720 from the network server 220 to form the final boot image 1730. Generates and displays a home screen 1600 on the display 180, corresponding to the generated final boot image 1730.
By displaying the home screen in this manner, the home screen can be displayed by fast booting.
14A to 14C illustrate that a home screen for a user selected through a user selection object is displayed when the power is turned on.
Referring to the drawings, as shown in FIG. 14A, when the power key of the remote control apparatus 200 operates while the image display apparatus 100 is turned off, as shown in FIG. 14B, any one of a plurality of users. A user selection object 2010 capable of selecting may be displayed.
When there are a plurality of users of the image display apparatus 100, a home screen for each user may be configured. In an embodiment of the present invention, the final display home screen for each user is displayed as it is when the power is turned on.
To this end, as shown in FIG. 14B, the user selection object 2010 may be immediately displayed on the display 180 when the power is turned on.
When a specific user is selected through the user selection object 2010, the processor 330 requests the network server 220 to transmit a dynamic boot image associated with the selected user. Accordingly, network server 220 transmits a dynamic boot image associated with the selected user.
The processor 330 combines the dynamic boot image associated with the selected user with the fixed boot image stored in the nonvolatile memory 1410 to generate a final boot image associated with the selected user. The home screen 1600 corresponding to the generated final boot image is displayed on the display 180 as illustrated in FIG. 14C.
14C, it can be seen that the object 2020 indicating that the first user is logged in is displayed on the home screen 1600.
As such, when the power is on, the user selection object is displayed and the final home screen for the selected user is displayed as it is, so that the user's convenience may be improved.
FIG. 15 is a flowchart illustrating a method of operating an image display apparatus according to another exemplary embodiment. FIG. 16 is a view referred to for describing various examples of the method of operating the image display apparatus of FIG. 15.
Referring to the drawing, first, it is determined whether the power is off (S2110). For example, when the power key of the local key (not shown) of the video display device 100 or the power key of the remote control device 200 is operated, the power-off signal passes through the user input interface unit 150. It may be delivered to the controller 170. In more detail, it may be delivered to the processor 330 in the control unit 170.
The processor 330 transmits a power off signal to the power supply 190. Accordingly, the power supply unit 190 stops supplying power to the image display device 100.
On the other hand, the processor 330 may be supplied with standby power to generate the following dynamic boot image.
Next, when the power is off, the final boot image based on the final home screen displayed on the display 180 is called (S2120). The fixed boot image previously stored in the nonvolatile memory is called (S2130).
When the power is turned off, the processor 330 calls the final boot image based on the final home screen displayed on the display 180.
In general, screen contents to be displayed, in particular, home screen contents are resident in the volatile memory 1420, and the processor 330 transmits them to the OSD generator 340, and the OSD generator 340 is a mixer 350. ), The home screen is displayed on the display 180.
When the power is turned off, the processor 330 calls a boot image temporarily stored in the volatile memory 1420, that is, the final boot image. The processor 330 then calls a fixed boot image stored in the nonvolatile memory 1410.
Next, the dynamic boot image is extracted based on the final boot image and the fixed boot image (S2130).
When the final boot image and the fixed boot image are called, the processor 330 generates a dynamic boot image by using the final boot image and the fixed boot image.
The dynamic boot image may correspond to an image except for the fixed boot image on the final home screen displayed at power off.
In this case, the dynamic boot image may include information indicating the location of the dynamic boot image and information indicating the content of the dynamic boot image. In addition, the dynamic boot image may further include user information. As described above with reference to FIGS. 14A to 14C, it is also possible to extract a dynamic boot image for each user.
For example, when the end user is the first user at power off, the extracted dynamic boot image may be a dynamic boot image for the first user.
Meanwhile, before the power off, when the second user watches the home screen and logs out, similarly to the power off, the dynamic boot image for the second user is automatically extracted and the information is transferred to the network server 220. It is also possible to transmit.
Next, the extracted dynamic boot image is transmitted to the network server (S2135).
The dynamic boot image extracted by the processor 330 may be delivered to the network interface unit 130, and the network interface unit 130 may transmit the dynamic boot image to the network server 220 through a network.
Accordingly, the dynamic boot image at power off can be easily stored in the network server.
As such, by extracting the dynamic boot image and storing it in the network server 220, when the power is turned on in the future, it can be easily used.
In particular, by storing the dynamic boot image outside the image display apparatus 100, not in the image display apparatus 100, and not in the memory in the image display apparatus 100, the lifespan of the memory in the image display apparatus 100 is reduced. Can be prevented.
10 illustrates generating a dynamic boot image using the final boot image and the fixed boot image.
Referring to the drawings, an area of the home screen 1500 of FIG. 9 except for the broadcast video area 1510 may correspond to the fixed boot image 2210.
Meanwhile, when the home screen 1600 of FIG. 10 is displayed when the power is turned off, an area of the home screen 1600 of FIG. 10 except for the broadcast video region 1610 may correspond to the final boot image 2220.
The processor 330 extracts the dynamic boot image 2230 based on the fixed boot image 2210 and the final boot image 2220.
9 and 10, the dynamic boot image 2230 may include a second region 1620 where the tab menu of FIG. 10 is displayed, a partial region of the third region 1630 where a plurality of card objects are displayed, And the fourth area 1650 in which menu items are displayed.
In the drawing, the dynamic boot image 2230 is shown to include a first dynamic boot image 2225 and a second dynamic boot image 2228.
The first dynamic boot image 2225 and the second dynamic boot image 2228 may be images spaced apart from each other. Accordingly, the header 2226 of the first dynamic boot image 2225 may include information indicating the location of the first dynamic boot image 2225, and the data 2227 of the first dynamic boot image 2225 may be included. It may include information indicating the content of the first dynamic boot image 2225. Meanwhile, the dynamic boot image 2220 may further include user information.
The processor 330 transfers the generated dynamic boot image 2230 to the network interface unit 130. The network interface unit 130 transmits the generated dynamic boot image 2230 to the network server 220 through a network. Accordingly, the generated dynamic boot image 2230 is stored in the network server 220.
