FIG. 1 is a diagram showing an image display system for mirroring according to an embodiment of the present invention.

Referring to the drawing, an image display system 10 for mirroring may include an image display apparatus 100, a mobile terminal 600, and a server 500.

Thereamong, the image display apparatus 100 and the mobile terminal 600 may perform mirroring.

The present invention proposes a method of easily installing and displaying a mirroring application item from the mobile terminal 600 in the image display apparatus 100 for convenience of mirroring between the image display apparatus 100 and the mobile terminal 600.

To this end, the image display apparatus 100 may display a mirroring related menu including mirroring related server information or content associated with the server information, based on user input.

In this case, the mirroring related server information or the content associated with the server information may be information provided by a manufacturer of the image display apparatus 100.

The mobile terminal 600 may receive the mirroring related server information or the content associated with the server information, displayed in the mirroring related menu, and access the server 500 based on the received information.

The mobile terminal 600 may receive a mirroring-related application from the server 500 and may install and execute the mirroring-related application in the mobile terminal 600.

In addition, upon selecting an application item as a mirroring target through the executed mirroring-related application, the mobile terminal 600 may transmit the selected mirroring application item to the image display apparatus.

The image display apparatus 100 may receive the mirroring application item from the mobile terminal 600 through an interface unit 130 or 135 and may display the received mirroring application item in the mirroring related menu.

Accordingly, the mirroring application item may be easily installed and displayed on the image display apparatus 100.

The present invention proposes a method of easily mirroring and displaying a first mirroring application execution image when a first mirroring application item is selected while the mirroring application item from the mobile terminal 600 is installed and displayed on the image display apparatus 100.

To this end, when the first mirroring application item is selected among the mirroring application items displayed in the mirroring related menu, the image display apparatus 100 may transmit pairing information or first mirroring application execution request information to the mobile terminal 600, receive the first mirroring application execution image from the mobile terminal 600 through the network interface unit 135 or 135, and display the first mirroring application execution image on a display 180.

The drawing illustrates an example in which a radio signal Saib of a gallery image 840a of a gallery application executed in the mobile terminal 600 is transmitted to the image display apparatus 100 via mirroring between the image display apparatus 100 and the mobile terminal 600 and a gallery image 840b that is enlarged to correspond to a gallery application is displayed on the image display apparatus 100.

A size of the display 180 of the image display apparatus 100 is much larger than a size of a display 680 (refer to FIG. 5) of the mobile terminal 600 and, thus, a user may view an enlarged image via mirroring.

As an example of a mirroring method, when a mirroring mode is selected in the image display apparatus 100, the image display apparatus 100 may wirelessly transmit a pairing signal to the mobile terminal 600 and the mobile terminal 600 may transmit a pairing response signal in response to the pairing signal and, accordingly, the mobile terminal 600 and the image display apparatus 100 may access each other.

In this case, the pairing signal and the pairing response signal may be a Bluetooth-based Bluetooth low energy (BLE) signal.

In this case, the image display apparatus 100 may further transmit device information including a device ID as well as the pairing signal to the mobile terminal 600.

As another example of the mirroring method, when the mirroring mode is selected in the mobile terminal 600, the mobile terminal 600 may wirelessly transmit a pairing signal to the image display apparatus 100 and the image display apparatus 100 may transmit a pairing response signal in response to the pairing signal and, accordingly, the mobile terminal 600 and the image display apparatus 100 may access each other.

After access, the mobile terminal 600 may wirelessly transmit an application image related to execution of mirroring to the image display apparatus 100. For example, the mobile terminal 600 may wirelessly transmit the application image to the image display apparatus 100 via Wi-Fi using a Miracast method.

According to the present invention, for convenience of user use, a mirroring mode may be executed based on the image display apparatus 100.

The aforementioned various operation methods of the image display apparatus 100 and the mobile terminal 600 will be described in more detail with reference to FIG. 6 and drawings subsequent thereto.

The image display apparatus 100 of FIG. 1 may be a monitor, a TV, a tablet PC, or the like.

Referring to FIG. 2, the image display apparatus 100 according to an embodiment of the present invention may include a broadcast receiver 105, the external device interface unit 130, a memory 140, a user input interface unit 150, a sensor (not shown), a controller 170, the display 180, and an audio output unit 185.

The broadcast receiver 105 may include a tuner 110, a demodulator 120, a network interface unit 135, and an external device interface unit 130.

Differently from the drawing, the broadcast receiver 105 may include only the tuner 110, the demodulator 120, and the external device interface unit 130. That is, the broadcast receiver 105 may not include the network interface unit 135.

The tuner 110 may tune to a radio frequency (RF) broadcast signal corresponding to a channel selected by a user or all pre-stored channels among RF broadcast signals received through an antenna (not shown). In addition, the selected RF broadcast signal may be converted into an intermediate frequency signal, a baseband image, or a voice signal.

For example, the selected RF broadcast signal may be converted into a digital IF (DIF) signal in the case of a digital broadcast signal and converted into an analog baseband image or a voice signal (CVBS/SIF) in the case of an analog broadcast signal. That is, the tuner 110 may process the digital broadcast signal or the analog broadcast signal. The analog baseband image or the voice signal (CVBS/SIF) output from the tuner 110 may be input directly to the controller 170.

The tuner 110 may sequentially select RF broadcast signals of all broadcast channels stored via a channel recording function among RF broadcast signals received through an antenna and may convert the RF broadcast signals into an intermediate frequency signal, a baseband image, or a voice signal.

To receive broadcast signals of a plurality of channels, the tuner 110 may include a plurality of tuners. Alternatively, the tuner 110 may include a single tuner for simultaneously receiving the broadcast signals of the plurality of channels.

The demodulator 120 may receive the digital IF (DIF) signal converted by the tuner 110 and demodulate the DIF signal.

The demodulator 120 may output a stream signal TS after demodulation and channel decoding. In this case, the stream signal may be obtained by multiplexing an image signal, a voice signal, or a data signal.

The stream signal output from the demodulator 120 may be input to the controller 170. The controller 170 may perform demultiplexing and image/voice signal processing to output an image to the display 180 and to output voice to the audio output unit 185.

The external device interface unit 130 may transmit or receive data to and from a connected external device (not shown), for example, a set-top box 50. To this end, the external device interface unit 130 may include an audio/video (A/V) input and output unit (not shown).

The A/V input and output unit may receive an image and voice signal of the external device. A wireless communication unit (not shown) may perform short-range communication with other electronic devices.

The external device interface unit 130 may exchange data with the mobile terminal 600 adjacent thereto through the wireless communication unit (not shown). In particular, the external device interface unit 130 may receive device information, executed application information, an application image, and so on from the mobile terminal 600 in a mirroring mode.

The network interface unit 135 may provide an interface for connecting the image display apparatus 100 to a wireless/wired network including the Internet. For example, the network interface unit 135 may receive content or data provided by the Internet, a content provider, or a network operator through a network.

The network interface unit 135 may include a wireless communication unit (not shown).

The memory 140 may store a program for processing and controlling each signal in the controller 170 and store the signal-processed image, voice, or data signals.

The memory 140 may temporally store the image, voice, or data signals input to the external device interface unit 130. In addition, the memory 140 may store information about a predetermined broadcast channel through a channel recording function such as a channel map.

Although FIG. 2 illustrates the case in which the memory 140 is included separately from the controller 170, the scope of the present invention is not limited thereto. The memory 140 may be included in the controller 170.

The user input interface unit 150 may forward a signal input by a user or forward a signal from the controller 170 to the user.

For example, the user input interface unit 150 may transmit/receive a user input signal such as power on/off, channel selection, and image setting to and from a remote controller 200, forward a user input signal input via a local key (not shown) such as a power key, a channel key, a volume key, and a setting key to the controller 170, forward a user input signal input from a sensor (not shown) for setting a user gesture to the controller 170, or transmit a signal from the controller 170 to a sensor (not shown).

The controller 170 may demultiplex a stream input through the tuner 110, the demodulator 120, the network interface unit 135, or the external device interface unit 130 or process demultiplexed signals to generate and output signals for output of an image or voice.

The image signal that is image-processed by the controller 170 may be input to the display 180 and may be displayed as an image corresponding to the corresponding image signal. In addition, the image signal that is image-processed by the controller 170 may be input to an external output device through the external device interface unit 130.

A voice processed by the controller 170 may be audibly output to the audio output unit 185. The voice signal processed by the controller 170 may be input to an external output device through the external device interface unit 130.

Although not shown in FIG. 2, the controller 170 may include a demultiplexer, an image processor, and so on, which will be described below with reference to FIG. 3.

In addition, the controller 170 may control an overall operation of the image display apparatus 100. For example, the controller 170 may control the tuner 110 to tune to RF broadcast corresponding to a channel selected by a user or a pre-stored channel.

In addition, the controller 170 may control the image display apparatus 100 according to an internal program or a user command input through the user input interface unit 150.

The controller 170 may control the display 180 to display an image. In this case, the image displayed on the display 180 may be a still image or a video image and may be a 2D image or a 3D image.

The controller 170 may display a predetermined 2D object in the image displayed on the display 180. For example, the object may be at least one of an accessed web image (a newspaper and a magazine), electronic program guide (EPG), various menus, widgets, an icon, a still image, a video image, and text.

The controller 170 may recognize a user position based on an image captured by a photographing unit (not shown). For example, the controller 170 may recognize a distance (z-axis coordinates) between a user and the image display apparatus 100. In addition, the controller 170 may recognize x-axis coordinates and y-axis coordinates on the display 180, which correspond to the user position.

The display 180 may convert an image signal, a data signal, an OSD signal, or a control signal, which is processed by the controller 170, an image signal, a data signal, or a control signal, which is received by the external device interface unit 130, or the like to generate a driving signal.

The display 180 may be a PDP, an LCD, an OLED, a flexible display, or the like and may be a 3D display. The 3D display 180 may be classified into a glassless mode and a glasses mode.

The display 180 may be configured as a touchscreen to be used as an input device as well as an output device.

The audio output unit 185 may receive the audio signal that is signal-processed by the controller 170 to output a corresponding sound.

The photographing unit (not shown) may photograph a user. The photographing unit (not shown) may include, but is not limited to, one camera and may include a plurality of cameras.

In addition, the remote controller 200 may receive image, voice, or data signals output from the user input interface unit 150 and display the signals or output voice through the remote controller 200.

The aforementioned image display apparatus 100 may be a stationary or mobile digital broadcast receiver that is capable of receiving digital broadcasts.

The block diagram of the image display apparatus 100 of FIG. 2 is a block diagram of an embodiment of the present invention. Components of the block diagram may be integrated, added, or omitted according to the specifications of the image display apparatus 100 that is actually embodied. That is, as necessary, two or more components may be integrated as one component or one component may be divided into two or more components. In addition, a function performed by each block is merely an embodiment of the present invention, and the scope of the present invention is not limited by a detailed operation or device.

FIG. 3 is an internal block diagram of an example of the controller of FIG. 2.

Referring to the drawing, the controller 170 according to an embodiment of the present invention may include a demultiplexer 310, an image processor 320, a processor 330, an OSD generator 340, a mixer 345, a frame rate converter 350, and a formatter 360. In addition, the controller 170 may further include an audio processor (not shown) and a data processor (not shown).

The demultiplexer 310 may demultiplex an input stream. For example, when MPEG-2 TS is input, the MPEG-2 TS may be demultiplexed to extract image, voice, and data signals. 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 130.

The image processor 320 may image-process 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 may decode the demultiplexed image signal and the scaler 335 may scale the resolution of the decoded image signal to output the image signal through the display 180.

The image decoder 325 may include various standards of decoders. For example, the image decoder 325 may include MPEG-2, and H. 264 decoders, a 3D image decoder of a color image and a depth image, a decoder of an image of a plurality of viewpoints, and so on.

The processor 330 may control an operation of the image display apparatus 100 or the controller 170. For example, the processor 330 may control the tuner 110 to tune to an RF broadcast corresponding to a channel selected by a user or a pre-stored channel.

The processor 330 may control the image display apparatus 100 according to an internal program or a user command input through the user input interface unit 150.

The processor 330 may control data transmission through the network interface unit 135 or the external device interface unit 130.

In addition, the processor 330 may control operations of the demultiplexer 310, the image processor 320, the OSD generator 340, and so on in the controller 170.

The OSD generator 340 may generate an OSD signal according to user input or autonomously. For example, the OSD generator 340 may generate a signal for displaying various information items as graphics or text on a monitor of the display 180 based on a user input signal. The generated OSD signal may include various data items such as a user interface image, various menu images, widgets, icons, and so on of the image display apparatus 100. In addition, the generated OSD signal may include a 2D object or a 3D object.

In addition, the OSD generator 340 may generate a pointer displayable on a display based on a pointing signal input from the remote controller 200. In particular, the pointer may be generated by a pointing signal processor, and the OSD generator 340 may include the pointing signal processor (not shown). Needless to say, the pointing signal processor (not shown) may not be disposed in the OSD generator 340 and may be separately provided from the OSD generator 340.

The mixer 345 may mix the OSD signal generated by the OSD generator 340 and the decoded image signal that is image-processed by the image processor 320. The mixed image signal may be provided to the frame rate converter 350.

The frame rate converter (FRC) 350 may convert a frame rate of an input image. The frame rate converter 350 may output the input image without change and without separate frame conversion.

The formatter 360 may arrange a left-eye image frame and a right-eye image frame of the 3D image with the converted frame rate. In addition, the formatter 360 may output a synchronization signal Vsync for opening a left-eye glass and a right-eye glass of a 3D viewing apparatus (not shown).

The formatter 360 may convert format of the input image signal into an image signal to be displayed on a display and may output the image signal.

The formatter 360 may change the format of a 3D image signal. For example, the format of a 3D image signal may be changed to any one of various 3D formats such as side by side format, top/down format, frame sequential format, interlaced format, and checker box format.

The formatter 360 may convert a 2D image signal into a 3D image signal. For example, according to a 3D image generation algorithm, an edge or a selectable object may be detected from the 2D image signal, and an object according to the detected edge or the selectable object may be extracted and generated as a 3D image signal. In this case, as described above, the generated 3D image signal may be separated into a left image signal L and a right image signal R and the left image signal L and the right image signal R may be arranged.

Although not shown, after the formatter 360, a 3D processor (not shown) for 3-dimensional (3D) effect signal processing may be further disposed. The 3D processor (not shown) may adjust the brightness, tint, and color of the image signal to enhance the 3D effect. For example, signal processing and so on may be performed to make a short distance be in focus and to make a long distance be out of focus. The function of the 3D processor may be integrated with the formatter 360 or the image processor 320.

The audio processor (not shown) in the controller 170 may voice-process the demultiplexed voice signal. To this end, the audio processor (not shown) may include various decoders.

The audio processor (not shown) in the controller 170 may adjust base, treble, volume, and so on.

The data processor (not shown) in the controller 170 may data-process the demultiplexed data signal. For example, when the demultiplexed data signal is an encoded data signal, the encoded data signal may be decoded. The encoded data signal may be electronic program guide (EPG) information including broadcast information such as start time and finish time of a broadcast program that is broadcast on each channel.

The block diagram of the controller 170 of FIG. 3 is a block diagram of an embodiment of the present invention. Components of the block diagram may be integrated, added, or omitted according to the specifications of the controller 170 that is actually embodied.

In particular, the frame rate converter 350 and the formatter 360 may not be disposed in the controller 170 but may be separately disposed from the controller 170 or may be provided as one module.

FIG. 4A is a diagram showing a control method of the remote controller of FIG. 2.

FIG. 4A(a) illustrates the case in which a pointer 205 corresponding to the remote controller 200 is displayed on the display 180.

A user may move or rotate the remote controller 200 up and down, right and left (FIG. 4A(b)), and forward and backward (FIG. 4A(c)). The pointer 205 displayed on the display 180 of the image display apparatus may correspond to movement of the remote controller 200. As shown in the drawing, the corresponding pointer 205 is moved and displayed according to movement in a 3D space and, thus, the remote controller 200 may be referred to as a spatial remote controller or a 3D pointing device.

FIG. 4A(b) illustrates the case in which, when a user moves the remote controller 200 to the left, the pointer 205 displayed on the display 180 of the image display apparatus is also moved to the left in response to the movement of the remote controller.

Information about movement of the remote controller 200, detected through the sensor of the remote controller 200, may be transmitted to the image display apparatus. The image display apparatus may calculate coordinates of the pointer 205 from the information about the movement of the remote controller 200. The image display apparatus may display the pointer 205 to correspond to the calculated coordinates.

FIG. 4A(c) illustrates the case in which a user moves the remote controller 200 away from the display 180 while pushing a specific button of the remote controller 200. Accordingly, a selected area of the display 180, corresponding to the pointer 205, may be zoomed in to be enlarged and displayed. On the other hand, when the user moves the remote controller 200 close to the display 180, the selected area of the display 180, corresponding to the pointer 205, may be zoomed out to be reduced and displayed.
