The demultiplexer 310 demultiplexes an input stream. For example, when an MPEG-2 TS is input, it may be demultiplexed and separated into video, audio, and data signals, respectively. Here, the stream signal input to the demultiplexer 310 may be a stream signal output from the tuner 110, the demodulator 120, or the external device interface unit 135.

The image processor 320 may perform image processing of the demultiplexed image signal. To this end, the image processor 320 may include an image decoder 325 and a scaler 335.

The image decoder 325 decodes the demultiplexed image signal, and the scaler 335 performs scaling to output the resolution of the decoded image signal on the display unit 180.

The video decoder 325 may include decoders of various standards.

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

Also, for example, when the demultiplexed video signal is a digital video broadcasting (DMB) scheme or an encoded video signal of H.264 standard according to DVB-H, it may be decoded by an H.264 decoder.

On the other hand, the video signal decoded by the image processor 320 is input to the mixer 350.

The OSD generator 340 generates an OSD signal according to a user input or itself. For example, based on a control signal from the user input interface unit 150, a signal for displaying various types of information on a screen of the display unit 180 as a graphic or text may be generated. 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 can be overlaid on the broadcast image or the external input image.

The frame rate converter (FRC) 355 may convert the frame rate of the input video. For example, a 60Hz frame rate is converted to 120Hz or 240Hz. When converting a frame rate of 60 Hz to 120 Hz, it is possible to insert the same first frame or insert a third frame predicted from the first frame and the second frame between 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 three predicted frames. On the other hand, it is also possible to maintain the input frame rate without additional 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 unit 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 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.

The speech processing unit (not shown) in the controller 170 may decode the demultiplexed speech signal if it is an encoded speech signal. For example, the demultiplexed speech signal may be decoded by an MPEG-2 decoder, or an MPEG 4 decoder, or an AAC decoder, or an AC-3 decoder.

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 Program Guide) information including broadcast information such as a start time and an end time of a broadcast program broadcasted in 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-Service Information (DVB-SI) in the case of the DVB scheme. . The ATSC-PSIP information or the DVB-SI information may be information included in the aforementioned stream, that is, the header (4 bytes) of the MPEG-2 TS.

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

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

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

Next, when the content is played back, an image related to the played content is displayed (S1110).

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

In addition, although not shown in the drawing, when the audio file is played, an image (not shown) indicating that the audio file is played may be displayed on the display unit 180. In addition, when a predetermined web server is connected 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 played, an image (not shown) indicating that the e-book file is played may be displayed on the display unit 180.

Next, it is determined whether there is a pause input of the content to be played back (S1115). If applicable, the content to be played is paused (S1120). In this case, an image related to the paused content is displayed on the display unit 180 (S1125). For example, if the content being played is a broadcast video, the broadcast video at the paused time point is displayed on the display unit 180.

The pause input of the content may be input by inputting a specific key in the remote control apparatus 200 or by entering a corresponding menu and selecting a content pause item. Meanwhile, an application for pausing content may be executed.

12B illustrates that the paused broadcast image 1220 is displayed on the display unit 180. In this case, the display unit 180 may display an object 1230 indicating that it is paused. As a result, the user can intuitively recognize that the user is paused.

Meanwhile, an object 1240 indicating a pause time of the content (broadcast image) being played or an object 1244 indicating an elapsed time after the pause may be displayed in the lower area of the display 180. Thus, the user can easily grasp the time at which the pause is made or the elapsed time after the pause.

On the other hand, after the pause, if the content is a broadcast video, it is possible to store the broadcast video. Such a function may be referred to as digital video recording (DVR). This is for replaying from the paused point when the user returns to watching the broadcast again. Meanwhile, the amount of broadcast video stored may correspond to the object 1244 indicating the elapsed time since the pause.

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

 The display of the application menu may be performed by inputting a specific key in the remote control apparatus 200 or by entering the menu and selecting an 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 can 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.

FIG. 12C illustrates that the application menu 1250 is overlapped and displayed on the paused broadcast image 1220. In this case, as described above, the object 1240 indicating the pause time of the broadcast image or the object 1244 indicating the elapsed time after the pause may be displayed on the lower area of the display unit 180.

The application menu 1250 is a simple menu, in which application items having a high frequency of use by the user are preferably arranged.

In the drawing, a picture fitting application item 1252, a drawing application item 1254, a music setting application item 1256, an image reproducing application 1258 ) And the like. In addition, it may further include an enlarged view application item, a time setting application item, a preference application item, and the like.

Meanwhile, in the application menu 1250, an editing step of adding or deleting a predetermined application or changing an arrangement order may be separately performed according to a user's setting. As a result, an application item or the like that a user prefers can be added to the application menu 1250, thereby increasing user convenience.

12C is different from FIG. 12C in that the second application menu 1260 is further displayed in the lower region of the display unit 180 in addition to the application menu 1250.

The second application menu 1260 may include an application item executed through an external content provider or an external network. In this regard, it may be differentiated from the application menu 1250 having an application item executed in the image display apparatus 100. In addition, when the application item is edited, a fixed application item that is not deleted may be provided, and thus may be differentiated from the application menu 1250. In addition, the second application menu 1260 may be set as a default when the home screen is configured.

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

12E illustrates selecting a picture matching application item 1252 of the application menu 1250 using the pointer 205 of the remote control apparatus 200. As a result, the picture matching application is executed.

13A illustrates an execution screen 1310 of the picture matching application based on the paused broadcast video 1220. The execution screen 1310 of the picture matching application illustrates that the paused broadcast video 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 to fit the original paused broadcast image 1220.

Such an application may be executed for a short time, such as while an advertisement video is displayed on the broadcast video being viewed, thereby increasing user convenience.

Next, when the application is executed, a timer object indicating an execution time of the application is displayed or an object capable of replaying the paused content is displayed (S1145).

FIG. 13A illustrates that a timer object 1320 indicating an execution time of a picture matching application is displayed at the bottom of the display unit 180. As a result, the user can easily return to the broadcast video again at the end 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 picture matching application.
