The image processing unit 320 may perform image processing of the demultiplexed image signal. For this, the image processing unit 320 may include a video decoder 325 and a scaler 335.

The video decoder 325 decodes the demultiplexed video signal and the scaler 335 performs scaling so that the resolution of the decoded video signal can be output from the display unit 180.

The video decoder 325 can include a decoder of various standards.

For example, if the demultiplexed video signal is an MPEG-2 standard encoded video signal, it can be decoded by an MPEG-2 decoder.

Also, for example, if the demultiplexed video signal is an encoded video signal of the H.264 standard according to the DMB (Digital Multimedia Broadcasting) scheme or DVB-H, it can be decoded by the H.264 decoder.

Meanwhile, the video signal decoded by the video processor 320 is input to the mixer 350.

The OSD generation unit 340 generates an OSD signal according to a user input or by itself. For example, based on a control signal from the user input interface unit 150, a signal for displaying various kinds of information in a graphic or text format can be generated on the screen of the display unit 180. The generated OSD signal may include various data such as a user interface screen of the video display device 100, various menu screens, a widget, and an icon.

For example, the OSD generating unit 340 may generate a signal for displaying broadcast information based on a caption of a broadcast image or an EPG.

The mixer 350 may mix the OSD signal generated by the OSD generator 340 and the decoded video signal processed by the image processor 220. The mixed signal is provided to formatter 360. Since the decoded broadcast video signal or the external input signal and the OSD signal are mixed, the OSD can be overlaid on the broadcast image or the external input image.

A frame rate converter (FRC) 355 can convert a frame rate of an input image. For example, a frame rate of 60 Hz is converted to 120 Hz or 240 Hz. When converting the frame rate of 60 Hz to 120 Hz, it is possible to insert the same first frame between the first frame and the second frame, or insert the third frame predicted from the first frame and the second frame. When converting a frame rate of 60 Hz to 240 Hz, it is possible to insert three more identical frames or insert three predicted frames. On the other hand, it is also possible to maintain the input frame rate without performing another conversion.

The formatter 360 receives the output signal of the frame rate conversion unit 355 and changes the format of the signal to be suitable for the display unit 180 and outputs the signal. For example, the R, G, and B data signals may be output as low voltage differential signaling (LVDS) signals or mini-LVDS signals.

On the other hand, the audio processing unit (not shown) in the control unit 170 can perform the audio processing of the demultiplexed audio signal. To this end, the voice processing unit (not shown) may include various decoders.

When a demultiplexed speech signal is a coded speech signal, the speech processing unit (not shown) in the control unit 170 can decode the demultiplexed speech signal. For example, the demultiplexed speech signal may be decoded by an MPEG-2 decoder, an MPEG 4 decoder, an AAC decoder, or an AC-3 decoder.

In addition, the audio processing unit (not shown) in the control unit 170 can process a base, a treble, a volume control, and the like.

The data processing unit (not shown) in the control unit 170 can perform data processing of the demultiplexed data signal. For example, if the demultiplexed data signal is a coded data signal, it can be decoded. The encoded data signal may be EPG (Electronic Program Guide) information including broadcast information such as a start time and an end time of a broadcast program broadcasted on each channel. For example, the EPG information may be ATSC-PSIP (ATSC-Program and System Information Protocol) information in the case of the ATSC scheme and may include DVB-SI information in the DVB scheme . The ATSC-PSIP information or DVB-SI information may be information included in the above-described stream, i.e., the header (4 bytes) of the MPEG-2 TS.

Meanwhile, the block diagram of the controller 170 shown in FIG. 4 is a block diagram for an embodiment of the present invention. Each component of the block diagram can be integrated, added, or omitted according to the specifications of the control unit 170 actually implemented.

For example, the library 435 may include a security related library such as Secure Socket Layer (SSL), WebKit (WebKit) related to Web engine, libc (c library), video format and audio format A media framework such as a media-related library, and the like. Such a library 435 may be written on a C or C ++ basis. It can also be exposed to the developer through the framework 440.

The library 435 may include a runtime 437 having a core Java library and a virtual machine (VM). This runtime 437 forms the basis of the framework 440 along with the library 435.

The virtual machine (VM) can be a plurality of instances, that is, a virtual machine that can perform multitasking. On the other hand, each virtual machine (VM) may be allocated and executed in accordance with each application in the application layer 455, at which time a binder (not shown) in the OS kernel 410, for scheduling or inter- Binder) driver (not shown) may be operated.

Meanwhile, the binder driver and the runtime 437 can connect a Java-based application and a C-based library.

On the other hand, the library 435 and the runtime 437 can correspond to the middleware of the legacy system.

On the other hand, the framework 440 in the smart system platform 405 includes a program that is the basis of the application in the application layer 455. The framework 440 is compatible with any application and may be capable of reusing, moving or exchanging components. The framework 440 may include a support program, a program for weaving other software components, and the like. For example, a resource manager, an activity manager associated with an activity of an application, a notification manager, a content provider that summarizes shared information between applications, and the like . Such a framework 440 can be created based on Java (JAVA).

The application layer 455 on the framework 440 includes various programs that can be displayed and driven in the video display device 100.

Referring to the drawings, the remote control device 200 can transmit and receive signals in accordance with the RF communication standard or the IR communication standard with the image display device 100. [

FIG. 7A illustrates that the pointer 205 corresponding to the remote control device 200 is displayed on the display unit 180. FIG.

The user can move or rotate the remote control device 200 up and down, left and right (Fig. 7 (b)), and back and forth (Fig. 7 (c)). The pointer 205 displayed on the video display device 100 corresponds to the motion of the remote control device 200. [ In this remote control device 200, as shown in the figure, since the pointer 205 is moved according to the movement in the 3D space, it can be called a space remote controller.

7B illustrates that when the user moves the remote control device 200 to the left, the pointer 205 displayed on the video display device 100 moves to the left correspondingly. Information on the motion of the remote control device 200 sensed through the sensor of the remote control device 200 is transmitted to the image display device 100. The image display device 100 can calculate the coordinates of the pointer 205 from information on the motion of the remote control device 200. [ The video display device 100 can display the pointer 205 so as to correspond to the calculated coordinates.

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

The pointer in the present specification means an object displayed on the display unit 180 in correspondence with the operation of the remote control device 200. [ Therefore, various shapes of objects other than the arrow shapes shown in the figure are possible with the pointer 205. [ For example, it can be a concept that includes points, cursors, prompts, thick outlines, and so on. The pointer 205 may be displayed corresponding to a point on a horizontal axis or a vertical axis on the display unit 180 or may be displayed corresponding to a plurality of points such as a line or a surface Do.

When the user input unit 235 has a touch screen, the user can touch a soft key of the touch screen to input a command related to the image display device 100 to the remote control device 200. [ In addition, the user input unit 235 may include various types of input means such as a scroll key, a jog key, and the like that can be operated by the user, and the present invention does not limit the scope of the present invention.

The sensor unit 240 may include a gyro sensor 241 or an acceleration sensor 243. The gyro sensor 241 can sense information on the motion of the remote control device 200. [ For example, the gyro sensor 241 can sense information on the operation of the remote control device 200 based on the x, y, and z axes. The acceleration sensor 243 can sense information on the moving speed of the remote control device 200 and the like. Meanwhile, a distance measuring sensor may be additionally provided, so that the distance to the display unit 180 can be sensed.

The output unit 250 may output an image or voice signal corresponding to the operation of the user input unit 235 or corresponding to the signal transmitted from the image display device 100. [ The user can recognize whether the user input unit 235 is operated or whether the video display device 100 is controlled through the output unit 250.

For example, the output unit 250 may include an LED module 251 that is turned on when a user input unit 235 is operated or a signal is transmitted and received between the image display device 100 and the image display device 100 through the wireless communication unit 225, 253 for outputting sound, an acoustic output module 255 for outputting sound, or a display module 257 for outputting an image.

9 to 10 are views for explaining various examples of the method of operating the image display device according to the embodiment of the present invention.

First, FIG. 9 illustrates that a list of applications on the network is displayed on the display unit 180. FIG. That is, it is possible for the user to directly access the content server or the network server to search for and download various applications.

FIG. 9A illustrates that various application lists 610 in the connected server are displayed on the display unit 180. FIG. The application list 610 may include an icon representing each application and a brief description information for each application. On the other hand, in the video display device 100, since full browsing is possible, it is possible to enlarge and display the size of the icon or explanation information received from the connected server. Thus, the user can easily grasp the application item. This will be described later.

Next, FIG. 9 (b) illustrates the selection of any one of the application items 620 of the application list 610 by using the pointer 205 of the remote control device 200. FIG. As a result, the application can be easily downloaded.

On the other hand, Fig. 10 illustrates that an application list in the video display device is displayed on the display.

10A shows an application list 660 stored in the video display device 100 on the display unit 180 when the user enters the application list view item by the operation of the remote control device 200. [ As shown in Fig. In the drawing, only the icon representing each application is illustrated, but the present invention is not limited thereto, and may include brief explanatory information for each application, as shown in FIG. Thus, the user can easily grasp the application item.

Next, FIG. 10 (b) illustrates the selection of any one of the application items 660 of the application list 1210 by using the pointer 205 of the remote control device 200. FIG. As a result, the application can be easily executed.

FIG. 11 is a flowchart illustrating an operation method of an image display device according to an exemplary embodiment of the present invention, and FIGS. 12A to 17C are diagrams for explaining various examples of an operation method of the image display device of FIG.

Referring to FIG. 11, first, content is played back (S1105).

The control unit 170 controls to reproduce the content. For example, the content reproduction can be performed by the content reproduction input from the remote control device 200 or a local key (not shown). The content may be content received in an external device connected to the video display device 100 or the video display device or via a network connected thereto. Such content may be at least one of a broadcast image, an external input image, an audio file, a still image, a connected web screen, and a document file.

Next, at the time of content reproduction, an image related to the content to be reproduced is displayed (S1110).

The control unit 170 controls to display an image related to the content to be reproduced at the time of content reproduction. For example, as shown in FIG. 12A, when a broadcast is reproduced, the corresponding broadcast image 1210 is displayed on the display unit 180.

In addition, although not shown in the drawing, when an audio file is reproduced, an image (not shown) indicating that the audio file is reproduced can be displayed on the display unit 180. In addition, when a predetermined web server is accessed through a network, a corresponding web screen (not shown) may be displayed on the display unit 180. In addition, when an e-book file is reproduced, an image (not shown) indicating that the e-book file is reproduced can be displayed on the display unit 180.

Next, it is determined whether there is a pause input of the content to be reproduced (S1115). If so, the playback content is temporarily stopped (S1120). At this time, an image related to the temporarily stopped contents is displayed on the display unit 180 (S1125). For example, if the content being reproduced is a broadcast image, the broadcast image at the time of the pause is displayed on the display unit 180.

The pause input of the content can be input by inputting a specific key in the remote control device 200 or by entering the menu and selecting a content pause item. On the other hand, it is also possible that an application for suspending contents is executed.

12B illustrates that the temporarily stopped broadcast image 1220 is displayed on the display unit 180. FIG. At this time, the display unit 180 may display an object 1230 indicating that it is temporarily stopped. Thereby, the user can intuitively recognize that the user is temporarily stopped.

In the lower area of the display unit 180, an object 1240 indicating a time point at which the content being reproduced (broadcast image) is temporarily stopped or an object 1244 indicating an elapsed time after the pause can be displayed. Thereby, the user can easily grasp the time point at which the user is temporarily stopped or the elapsed time after the temporary stop.

On the other hand, if the content is a broadcast image after the pause, it is possible to store the broadcast image. Such a function can be referred to as a digital video recording (DVR). This is to reproduce again from the point in time when it is temporarily stopped when returning to the broadcast viewing. On the other hand, the stored amount of the broadcast image may correspond to the object 1244 indicating the elapsed time since the above-described pause.

Next, an application menu having at least one application item executable based on the image related to the paused content or the content is displayed in the first area of the display (S1130).

 The display of the application menu can be performed by a specific key input in the remote control device 200 or by entering the menu and selecting the application menu display.

The application menu 1250 preferably includes at least one application item that is executable based on the paused content or an image related to the content. Accordingly, the user is able to provide a more friendly environment to the user by executing the application using the still image as it is while the broadcast image being viewed is paused.

12C illustrates that the application menu 1250 is superimposed and displayed on the paused broadcast image 1220. [ At this time, as described above, the object 1240 indicating the time point at which the broadcast image is temporarily stopped or the object 1244 indicating the elapsed time after the pause can be displayed in the lower region of the display unit 180.

The application menu 1250 is preferably an easy menu and an application item with a high frequency of use by the user is disposed.

In the drawing, a puzzle application 1252, a drawing application 1254, a music setting application 1256, an image reproduction application 1258, ). In addition, it may further include an enlarged view application item, a time setting application item, a configuration application item, and the like.

Meanwhile, in the application menu 1250, an editing step for adding or deleting a predetermined application or changing the arrangement order may be performed separately according to the setting of the user. This allows the user to add a favorite application item or the like to the application menu 1250, thereby enhancing the user's convenience.

12D differs from FIG. 12C in that, in addition to the application menu 1250, a second application menu 1260 is additionally displayed in a lower area of the display unit 180. FIG.

The second application menu 1260 may include an application item that runs through an external content provider or external network. In this regard, it can be differentiated from the application menu 1250 having an application item to be executed in the video display device 100. In addition, fixed application items can be provided that are not edited, edited, or otherwise edited with the application item, and can be differentiated from the application menu 1250 in this regard. In addition, the second application menu 1260 can be set as a default in the home screen configuration.

Next, it is determined whether there is a predetermined application execution command in the application menu (S1135), and if so, the corresponding application is executed (S1140).

Figure 12E illustrates the use of the pointer 205 of the remote control device 200 to select the snapshot application item 1252 in the application menu 1250. [ Thereby, the picture fitting application is executed.

13A illustrates an execution screen 1310 of a picture-snapping application based on a paused broadcast image 1220. FIG. An execution screen 1310 of the picture matching application illustrates that the paused broadcast image 1220 is divided into a plurality of pieces. Thereby, the user can move each piece by using the pointer 205 of the remote control device 200 and align it with the original paused broadcast image 1220.

Such an application can be executed for a short time, for example, while the advertisement image is displayed on the broadcast image being watched, so that the user's convenience of use can be increased.

Next, at the time of executing the application, a timer object indicating the execution time of the application is displayed or an object capable of reproducing the paused content is displayed (S1145).

13A illustrates that a timer object 1320 indicating the execution time of the picture-aligning application is displayed at the lower end of the display unit 180. [ Thereby, the user can easily return to the broadcast image again according to the end time of the advertisement or the like.

On the other hand, it is also possible to display an object 1325 indicating the end of execution of the pic- ture application. When this object 1325 is selected, the execution of the application is terminated. After the termination, the screen as shown in FIG. 12B can be returned.

Next, Fig. 13B is similar to Fig. 13A. However, instead of the object 1325 indicating the end of the execution of the application, an object (e.g., a video object) 1330) is displayed. As a result, the suspended broadcast image can be reproduced again.

Next, FIG. 14A illustrates that the drawing application item 1254 of the application menu 1250 illustrated in FIG. 12E is selected, and the drawing application is executed.

The pointer 205 of the remote control device 200 can be moved based on the suspended broadcast image 1220 to perform the drawing operation.
