[0057] The present invention will now be described in further detail with reference to the accompanying drawings.

[0058] The suffixes “module” and “part” used for constituent elements in the following description are merely for the purpose of facilitating the preparation of the description and do not have any particularly important meaning or function in themselves. Therefore, the terms “module” and “part” may be used interchangeably.

[0059] Figure 1 This is an example of an image display system illustrating an embodiment of the present invention.

[0060] Referring to the accompanying drawings, an image display system 10 according to an embodiment of the present invention may include an image display device 100, a mobile terminal 600, a server 500, and a broadcast provider 30.

[0061] In addition, the image display system 10 may also include another image display device 100b, another mobile terminal 600b, etc., that can be connected via a network.

[0062] An image display device 100 of one embodiment of the present invention receives a broadcast signal from a broadcast provider 30 and chat dialogue content from a server 500, synchronizes the broadcast image corresponding to the broadcast signal and the chat dialogue content, overlays the chat dialogue content on the broadcast image, and displays the dialogue content and transmits the dialogue content to the server 500 when the dialogue content is input based on a signal from a remote control device 200.

[0063] Thus, by connecting to server 500, broadcast images and chat dialogues corresponding to the selected channel can be displayed simultaneously from multiple broadcast channels, while dialogue content can be entered and displayed.

[0064] On the other hand, in one embodiment of the present invention, the image display device 100 displays a plurality of broadcast channel thumbnails to display chat conversation content. When a certain thumbnail is selected from the plurality of broadcast channel thumbnails, a broadcast image corresponding to the selected thumbnail is received from the broadcast provider 30, and the device connects to the server 500 to receive the chat conversation content corresponding to the selected broadcast image from the server 500. Thus, the selection of broadcast channels and chat conversation content can be conveniently performed using a plurality of broadcast channel thumbnails.

[0065] On the other hand, in one embodiment of the present invention, the image display device 100 connects to the server 500 based on the first account information, receives the first chat dialogue content corresponding to the first broadcast image selected from the server 500, synchronizes the first broadcast image and the first chat dialogue content, overlays the first chat dialogue content on the first broadcast image, displays the first dialogue content based on the signal input of the first dialogue content from the remote control device 200, and transmits the first dialogue content to the server 500.

[0066] On the other hand, in one embodiment of the present invention, a mobile terminal 600 connects to a server 500 based on second account information that is different from the first account information, receives and displays first chat dialogue content corresponding to a first broadcast image selected from the server 500, displays second dialogue content when second dialogue content is input, and transmits the second dialogue content to the server 500.

[0067] On the other hand, another image display device 100b according to an embodiment of the present invention connects to the server 500 based on third account information, receives first chat dialogue content corresponding to the first broadcast image selected from the server 500, synchronizes the first broadcast image and the first chat dialogue content, displays the first chat dialogue content overlaid on the first broadcast image, displays the third dialogue content and transmits the third dialogue content to the server 500 when inputting third dialogue content based on a signal from the remote control device 200.

[0068] On the other hand, another mobile terminal 600b according to an embodiment of the present invention connects to the server 500 based on fourth account information different from the third account information, receives and displays first chat dialogue content corresponding to the first broadcast image selected from the server 500, displays the fourth dialogue content when the fourth dialogue content is input, and transmits the fourth dialogue content to the server 500.

[0069] As described above, through various image display devices and mobile terminals of an embodiment of the present invention, connected to server 500 based on different account information, chat dialogue content corresponding to the same broadcast image can be shared.

[0070] In particular, in one embodiment of the present invention, the various image display devices 100 and 100b are connected to the server 500 based on different account information, and can share the same broadcast image and chat dialogue content corresponding to the same broadcast image.

[0071] On the other hand, with Figure 1 The image display device 100b can be a TV, monitor, tablet PC, or vehicle display device, etc.

[0072] Figure 2 yes Figure 1 An example of an internal block diagram of an image display device.

[0073] Reference Figure 2 An image display device 100 according to an embodiment of the present invention may include an image receiving unit 105, an external device interface unit 130, a network interface unit 135, a storage unit 140, a user input interface unit 150, a sensor unit (not shown), a signal processing device 170, a display 180, and an audio output unit 185.

[0074] The image receiving unit 105 can receive input images. For example, the image receiving unit 105 can receive broadcast images or HDMI images, external input images such as streaming media images, etc.

[0075] The image receiving unit 105 may include a tuning unit 110, a demodulation unit 120, and an external device interface unit 130.

[0076] On the other hand, unlike the accompanying drawings, the image receiving unit 105 may also include a tuning unit 110, a demodulation unit 120, an external device interface unit 130, and a network interface unit 135.

[0077] The tuning unit 110 selects a user-selected channel or an RF broadcast signal corresponding to all pre-stored channels from the RF (Radio Frequency) broadcast signal received via an antenna (not shown). Additionally, it converts the selected RF broadcast signal into an intermediate frequency signal, a baseband image, or a voice signal.

[0078] On the other hand, in order to receive broadcast signals from multiple channels, the tuning unit 110 may have multiple tuners. Alternatively, it may be a single tuner that simultaneously receives broadcast signals from multiple channels.

[0079] The demodulation unit 120 receives the digital IF signal (DIF) converted in the tuning unit 110 and performs demodulation.

[0080] The demodulation unit 120 can output a streaming media signal (TS) after performing demodulation and channel decoding. At this time, the streaming media signal can be a signal multiplexed from image signals, voice signals, or data signals.

[0081] The streaming media signal output from the demodulation unit 120 can be input to the signal processing device 170. After performing inverse multiplexing, image / audio signal processing, etc., the signal processing device 170 can output an image on the display 180 and output audio to the audio output unit 185.

[0082] The external device interface 130 can transmit and receive data with a connected external device (not shown), such as a set-top box 50.

[0083] Therefore, the external device interface section 130 may include an A / V input / output section (not shown), a wireless communication section (not shown), etc.

[0084] The external device interface unit 130 can connect wirelessly or wirelessly to external devices such as DVD (Digital Versatile Disk), Blu-ray, game devices, cameras, camcorders, computers (laptops), and set-top boxes, and can also perform input / output operations with external devices.

[0085] The A / V input / output section within the external device interface section 130 can receive image and voice signals from external devices. On the other hand, the wireless communication section (not shown) within the external device interface section 130 can perform short-range wireless communication with other electronic devices.

[0086] Through this wireless communication unit (not shown), the external device interface unit 130 can exchange data with the adjacent mobile terminal 600. In particular, in mirror mode, the external device interface unit 130 can receive device information, running application information, application images, etc. from the mobile terminal 600.

[0087] The network interface unit 135 provides an interface for connecting the image display device 100 to a wired / wireless network, including the Internet. For example, the network interface unit 135 can receive content or data provided by the Internet or a content provider or network operator via a network.

[0088] On the other hand, the network interface unit 135 may include a wireless communication unit (not shown).

[0089] The storage unit 140 can store programs for processing and controlling various signals within the signal processing device 170, and can also store image, voice, or data signals for signal processing.

[0090] In addition, the storage unit 140 can also perform the function of temporarily storing image, voice, or data signals input to the external device interface unit 130. Furthermore, the storage unit 140 can store information related to designated broadcast channels through channel memory functions such as channel maps.

[0091] It shows Figure 2 In some embodiments, the storage unit 140 is separated from the signal processing device 170, but the scope of the invention is not limited thereto. The storage unit 140 may be included within the signal processing device 170.

[0092] The user input interface 150 transmits user input signals to the signal processing device 170, or transmits signals from the signal processing device 170 to the user.

[0093] For example, the remote control device 200 can send / receive user input signals such as power on / off, channel selection, and screen settings; or it can transmit user input signals input from local keys (not shown) such as power button, channel button, volume button, and setting value to the signal processing device 170; or it can transmit user input signals input from a sensor unit (not shown) that senses the user's posture to the signal processing device 170; or it can send signals from the signal processing device 170 to the sensor unit (not shown).

[0094] The signal processing device 170 can reverse multiplex the streaming media input through the tuning unit 110, demodulation unit 120, network interface unit 135, or external device interface unit 130, or generate and output signals for image or voice output by processing the reverse multiplexed signals.

[0095] For example, the signal processing device 170 receives broadcast signals or HDMI signals received from the image receiving unit 105, performs signal processing based on the received broadcast signals or HDMI signals, and can output the processed image signal.

[0096] The image signal processed in the signal processing device 170 is input to the display 180, and an image corresponding to the image signal can be displayed. Furthermore, the image signal processed in the signal processing device 170 can be input to an external output device via the external device interface 130.

[0097] The voice signal processed in the signal processing device 170 can be output as sound to the audio output unit 185. In addition, the voice signal processed in the signal processing device 170 can be input to an external output device through the external device interface unit 130.

[0098] Although not in Figure 2 As shown, the signal processing device 170 may include an inverting multiplexer, an image processing unit, etc. That is, the signal processing device 170 can perform various signal processing operations, and therefore can be implemented as a system-on-a-chip (SOC). This will be discussed later. Figure 3 Please provide an explanation.

[0099] In addition, the signal processing device 170 can control the overall operation within the image display device 100. For example, the signal processing device 170 can control the tuning unit 110 to select RF broadcasts corresponding to channels selected by the user or pre-stored channels.

[0100] In addition, the signal processing device 170 can control the image display device 100 according to user commands or internal programs input through the user input interface 150.

[0101] On the other hand, the signal processing device 170 can control the display 180 to display an image. At this time, the image displayed on the display 180 can be a static image or a dynamic image, and can be a 2D image or a 3D image.

[0102] On the other hand, the signal processing device 170 can display a specified object within the image displayed on the display 180. For example, the object can be at least one of the following: a connected webpage (newspaper, magazine, etc.), an EPG (Electronic Program Guide), various menus, controls, icons, still images, moving images, and text.

[0103] On the other hand, the signal processing device 170 can identify the user's position based on the image captured by the imaging unit (not shown). For example, it can determine the distance (z-axis coordinate) between the user and the image display device 100. In addition, it can determine the x-axis and y-axis coordinates within the display 180 corresponding to the user's position.

[0104] The display 180 generates drive signals by converting image signals, data signals, OSD signals, control signals processed in the signal processing device 170 or image signals, data signals, control signals received from the external device interface unit 130.

[0105] On the other hand, the display 180 is composed of a touch screen and can be used as an input device in addition to being an output device.

[0106] The audio output unit 185 receives the voice signal processed in the signal processing device 170 and outputs it as voice.

[0107] A camera unit (not shown) photographs the user. The camera unit (not shown) can be implemented using a single camera, but is not limited to this; it can also be implemented using multiple cameras. The image information captured by the camera unit (not shown) can be input to the signal processing device 170.

[0108] The signal processing device 170 can sense the user's posture based on each or a combination of images captured by the imaging unit (not shown) or signals sensed by the sensor unit (not shown).

[0109] On the other hand, the signal processing device 170 can be implemented as a system on chip (SOC).

[0110] The power supply unit 190 can supply power to the entire image display device 100. In particular, the power supply unit 190 can supply power to the signal processing device 170, the display 180 for image display, and the audio output unit 185 for audio output, which are implemented in the form of a system on chip (SOC).

[0111] Specifically, the power supply unit 190 may have a converter that converts AC power to DC power and a DC / DC converter that converts the level of the DC power.

[0112] The remote control device 200 can send user input to the user input interface 150. For this purpose, the remote control device 200 can use Bluetooth, RF (Radio Frequency) communication, infrared (IR) communication, UWB (Ultra Wide Bandwidth), ZigBee, etc. Furthermore, the remote control device 200 receives image, voice, or data signals output from the user input interface 150 and displays or outputs them to the remote control device 200.

[0113] On the other hand, the image display device 100 described above can be a digital broadcast receiver capable of receiving fixed or mobile digital broadcasts.

[0114] on the other hand, Figure 2 The block diagram of the image display device 100 shown is a block diagram for an embodiment of the present invention. The various components of the block diagram can be combined, added, or omitted according to the specifications of the actually implemented image display device 100. That is, as needed, two or more components can be combined into one component, or one component can be divided into two or more components. Furthermore, the functions performed in each block are used to illustrate embodiments of the present invention, and their specific actions or devices do not limit the scope of the present invention.

[0116] Referring to the accompanying drawings, a signal processing apparatus 170 according to an embodiment of the present invention may include an inverting multiplexer 310, an image processing unit 320, a processor 330, and an audio processing unit 370. In addition, it may also include a data processing unit (not shown).

[0117] The inverse multiplexing unit 310 performs inverse multiplexing on the input streaming media. For example, when inputting MPEG-2TS, inverse multiplexing can separate it into image, voice, and data signals. Here, the streaming media signal input to the inverse multiplexing unit 310 can be a streaming media signal output from the tuning unit 110, the demodulation unit 120, or the external device interface unit 130.

[0118] The image processing unit 320 can perform signal processing on the input image. For example, the image processing unit 320 can perform image processing on the image signal that has been inversely multiplexed by the inverse multiplexing unit 310.

[0119] Therefore, the image processing unit 320 may include an image decoder 325, a scaler 335, an image quality processing unit 635, an image encoder (not shown), an OSD processing unit 340, a frame rate conversion unit 350, and a formatter 360, etc.

[0120] The image decoder 325 decodes the inversely multiplexed image signal, and the scaler 335 can perform scaling to output the resolution of the decoded image signal on the display 180.

[0121] The image decoder 325 can have decoders of various specifications. For example, MPEG-2 and H.264 decoders, 3D image decoders for color images and depth images, and decoders for multiple viewpoint images.

[0122] The scaler 335 can scale the input image signal that has been decoded in the image decoder 325, etc.

[0123] For example, when the size or resolution of the input image signal is small, the scaler 335 can perform up scaling, and when the size or resolution of the input image signal is large, it can perform down scaling.

[0124] The image quality processing unit 635 can perform image quality processing on the input image signal that has been decoded in the image decoder 325, etc.

[0125] For example, the image quality processing unit 635 can perform noise removal processing on the input image signal, expand the grayscale resolution of the input image signal, or perform image resolution enhancement, high dynamic range (HDR) based signal processing or change the frame rate, or perform panel characteristics, especially image quality processing corresponding to organic light-emitting panels, etc.

[0126] The OSD processing unit 340 generates OSD signals based on user input or spontaneously. For example, it can generate signals for displaying various information in graphics or text on the screen of the display 180 based on user input signals. The generated OSD signals can include various data such as user interface screens, menu screens, controls, and icons of the image display device 100. In addition, the generated OSD signals can include 2D objects or 3D objects.

[0127] Furthermore, the OSD processing unit 340 can generate a cursor that can be displayed on the screen based on the cursor signal input from the remote control device 200. In particular, this cursor can be generated in a cursor signal processing device, which the OSD processing unit 240 may include (not shown). Of course, the cursor signal processing device (not shown) may also be provided separately and not within the OSD processing unit 240.

[0128] The frame rate converter (FRC) 350 can convert the frame rate of the input image. On the other hand, the frame rate converter 350 can also output directly without the need for separate frame rate conversion.

[0129] On the other hand, Formatter 360 can convert the format of the input image signal into an image signal that can be displayed on the monitor and then output it.

[0130] In particular, Formatter 360 can change the format of image signals to match the display panel.

[0131] On the other hand, Formatter 360 can also change the format of image signals. For example, it can change the format of 3D image signals to one of various 3D formats, such as side-by-side, top / down, frame sequence, interlaced, and checker box formats.

[0132] The processor 330 can control the overall operation within the image display device 100 or the signal processing device 170.

[0133] For example, the processor 330 can control the tuner 110 to select RF broadcasts corresponding to channels chosen by the user or pre-stored channels.

[0134] In addition, the processor 330 can control the image display device 100 according to user commands or internal programs input through the user input interface 150.

[0135] In addition, the processor 330 can perform data transmission control with the network interface unit 135 or the external device interface unit 130.

[0136] In addition, the processor 330 can control the operation of the inverted multiplexer 310, the image processing unit 320, etc. in the signal processing device 170.

[0137] On the other hand, the audio processing unit 370 within the signal processing apparatus 170 can perform speech processing on inversely multiplexed speech signals. Therefore, the audio processing unit 370 can have various decoders.

[0138] In addition, the audio processing unit 370 within the signal processing device 170 can handle baseband, treble, volume adjustment, etc.

[0139] The data processing unit (not shown) within the signal processing apparatus 170 can perform data processing on the inversely multiplexed data signal. For example, if the inversely multiplexed data signal is an encoded data signal, it can be decoded. The encoded data signal may be electronic program guide information that includes broadcast information such as the start and end times of broadcast programs displayed on various channels.

[0140] on the other hand, Figure 3 The block diagram of the signal processing apparatus 170 shown is a block diagram for one embodiment of the present invention. The various components of the block diagram can be combined, added, or omitted according to the specifications of the actual implemented signal processing apparatus 170.

[0141] In particular, the frame rate conversion unit 350 and the formatter 360 can be respectively located outside the image processing unit 320.

[0142] Figure 4a It is shown Figure 2 A diagram illustrating the control method of a remote control device.

[0143] like Figure 4a As shown in (a), a cursor 205 corresponding to the remote control device 200 is displayed on the display 180.

[0144] Users can remotely control the device up and down, left and right (200). Figure 4a (b) of, before and after ( Figure 4a (c) Movement or rotation. The cursor 205 displayed on the display 180 of the image display device corresponds to the movement of the remote control device 200. As shown, since the corresponding cursor 205 of this remote control device 200 moves and is displayed according to its movement in 3D space, it can be named a space remote control or a 3D cursor device.

[0145] Figure 4a Example (b) illustrates that if the user moves the remote control device 200 to the left, the cursor 205 displayed on the display 180 of the image display device also moves to the left accordingly.

[0146] Information related to the movement of the remote control device 200, sensed by the sensors of the remote control device 200, is transmitted to the image display device. The image display device can calculate the coordinates of the cursor 205 from the information related to the movement of the remote control device 200. The image display device can display the cursor 205 in a manner corresponding to the calculated coordinates.

[0147] Figure 4a Example (c) illustrates a case where, with a specific button within the remote control device 200 pressed, the user moves the remote control device 200 away from the display 180. As a result, the selection area on the display 180 corresponding to the cursor 205 can be zoomed in and enlarged. Conversely, when the user moves the remote control device 200 closer to the display 180, the selection area on the display 180 corresponding to the cursor 205 can be zoomed out and reduced in size. Alternatively, the selection area can be zoomed out when the remote control device 200 is away from the display 180, and zoomed in when the remote control device 200 is close to the display 180.

[0148] On the other hand, when a specific button within the remote control device 200 is pressed, the recognition of up / down and left / right movement can be excluded. That is, when the remote control device 200 moves away from or towards the display 180, only forward / backward movement can be recognized, while up / down, left / right movement is not. When the specific button within the remote control device 200 is not pressed, only the cursor 205 moves according to the up / down, left / right movement of the remote control device 200.

[0149] On the other hand, the moving speed or moving direction of the cursor 205 can correspond to the moving speed or moving direction of the remote control device 200.

[0150] Figure 4b yes Figure 2 Internal block diagram of the remote control device.

[0151] Referring to the accompanying drawings, the remote control device 200 may include a wireless communication unit 420, a user input unit 430, a sensor unit 440, an output unit 450, a power supply unit 460, a storage unit 470, and a control unit 480.

[0152] The wireless communication unit 420 transmits and receives signals with any of the image display devices in the aforementioned embodiments of the present invention. Among the plurality of image display devices in the embodiments of the present invention, one image display device 100 will be described as an example.

[0153] In this embodiment, the remote control device 200 may have an RF module 421, which can transmit and receive signals with the image display device 100 according to RF communication specifications. Additionally, the remote control device 200 may have an IR module 423, which can transmit and receive signals with the image display device 100 according to IR communication specifications.

[0154] In this embodiment, the remote control device 200 transmits a signal including information related to the movement of the remote control device 200 to the image display device 100 via the RF module 421.

[0155] Additionally, the remote control device 200 can receive signals transmitted by the image display device 100 via the RF module 421. Furthermore, the remote control device 200 can transmit commands related to power on / off, channel change, volume change, etc., to the image display device 100 via the IR module 423 as needed.

[0156] The user input unit 430 may be composed of a keyboard, buttons, a touchpad, or a touchscreen. The user can input commands related to the image display device 100 to the remote control device 200 by operating the user input unit 430. If the user input unit 430 has physical buttons, the user can input commands related to the image display device 100 to the remote control device 200 by pressing the physical buttons. If the user input unit 430 has a touchscreen, the user can input commands related to the image display device 100 to the remote control device 200 by touching the soft keys on the touchscreen. Furthermore, the user input unit 430 may have various types of input devices that the user can operate, such as scroll keys or microswitches; this embodiment does not limit the scope of the invention.

[0157] The sensor unit 440 may include a gyroscope sensor 441 or an accelerometer sensor 443. The gyroscope sensor 441 can sense information related to the movement of the remote control device 200.

[0158] As an example, the gyroscope sensor 441 can sense information related to the operation of the remote control device 200 with reference to the x, y, and z axes. The accelerometer sensor 443 can sense information related to the moving speed of the remote control device 200. On the other hand, a distance measurement sensor may also be included, thereby allowing the sensing of the distance between the remote control device 200 and the display 180.

[0159] The output unit 450 can output image or voice signals corresponding to the operation of the user input unit 430 or to the signals transmitted from the image display device 100. Through the output unit 450, the user can identify whether the user input unit 430 is operated or whether the image display device 100 is controlled.

[0160] As an example, the output unit 450 may include an LED module 451 that lights up when operating the user input unit 430 or transmitting and receiving signals with the image display device 100 via the wireless communication unit 420, a vibration module 453 that generates vibration, a sound output module 455 that outputs sound, or a display module 457 that outputs images.

[0161] The power supply unit 460 supplies power to the remote control device 200. If the remote control device 200 remains stationary for a specified period, the power supply unit 460 interrupts the power supply, thereby reducing power waste. The power supply unit 460 can restore the power supply by operating a designated key on the remote control device 200.

[0162] The storage unit 470 can store various types of programs, application data, etc., required for the control or operation of the remote control device 200. If the remote control device 200 and the image display device 100 wirelessly transmit and receive signals via the RF module 421, the remote control device 200 and the image display device 100 transmit and receive signals via a specified frequency band. The control unit 480 of the remote control device 200 can store information such as the frequency band of the image display device 100 that can wirelessly transmit and receive signals with the remote control device 200 in the storage unit 470 for reference.

[0163] The control unit 480 controls all matters related to the control of the remote control device 200. The control unit 480 can transmit signals corresponding to the operation of a specified key on the user input unit 430 or signals corresponding to the movement of the remote control device 200 sensed in the sensor unit 440 to the image display device 100 via the wireless communication unit 420.

[0164] The user input interface 150 of the image display device 100 may include: a wireless communication unit 411, which is capable of wirelessly transmitting and receiving signals with the remote control device 200; and a coordinate value calculation unit 415, which calculates the coordinate value of the cursor corresponding to the action of the remote control device 200.

[0165] The user input interface unit 150 can wirelessly transmit and receive signals with the remote control device 200 via the RF module 412. Additionally, via the IR module 413, signals transmitted by the remote control device 200 can be received according to IR communication specifications.

[0166] The coordinate calculation unit 415 corrects for hand tremors or errors in the signal corresponding to the action of the remote control device 200 received through the wireless communication unit 411, thereby being able to calculate the coordinate values ​​x and y of the cursor 205 to be displayed on the display 170.

[0167] The transmission signal from the remote control device 200, input through the user input interface 150, is transmitted to the signal processing device 170 of the image display device 100. The signal processing device 170 determines information related to the operation and key operation of the remote control device 200 from the signal transmitted by the remote control device 200, and can control the image display device 100 accordingly.

[0168] As another example, the remote control device 200 can calculate the cursor coordinates corresponding to the action and output them to the user input interface 150 of the image display device 100. In this case, the user input interface 150 of the image display device 100 can transmit information related to the received cursor coordinates to the signal processing device 170 without additional correction for hand tremors or errors.

[0169] Alternatively, as another example, unlike the attached figure, the coordinate value calculation unit 415 may also be located inside the signal processing device 170 instead of the user input interface unit 150.

[0182] The sensing unit 640 can generate a sensing signal for controlling the operation of the mobile terminal 600 by sensing the current state of the mobile terminal 600, such as the open / closed state of the mobile terminal 600, the position of the mobile terminal 600, and whether or not a user is touching it.

[0183] The sensing unit 640 may include a proximity sensor 641, a pressure sensor 643, and a motion sensor 645. The motion sensor 645 may use an accelerometer, a gyroscope, a gravity sensor, etc., to sense the movement or position of the mobile terminal 600. In particular, the gyroscope is a sensor that measures angular velocity and can sense the direction (angle) of rotation relative to a reference direction.

[0184] The output unit 650 may include a display 680, an audio output unit 653, a notification unit 655, and a haptic module 657, etc.

[0187] The audio output unit 653 outputs audio data received from the wireless communication unit 610 or stored in the memory 660. This audio output unit 653 may include a speaker, a buzzer, etc.

[0188] The notification unit 655 outputs a signal to notify the mobile terminal 600 of an event that has occurred. For example, the signal can be output in the form of vibration.

[0189] The haptic module 657 produces various tactile effects that the user can perceive. A representative example of the tactile effects produced by the haptic module 657 is vibration.

[0190] The memory 660 can also store programs for processing and controlling the control unit 670, and can also perform functions for temporarily storing multiple data (e.g., phone books, messages, still images, moving images, etc.) for input or output.

[0191] The interface unit 625 performs the function of interfacing with all external devices connected to the mobile terminal 600. The interface unit 625 can receive data or power from such external devices and transmit it to the various components inside the mobile terminal 600, and data inside the mobile terminal 600 can be transmitted to external devices.

[0192] Typically, the control unit 670 controls the overall operation of the mobile terminal 600 by controlling the actions of the various units.

[0194] on the other hand, Figure 5The block diagram of the mobile terminal 600 shown is a block diagram for one embodiment of the present invention. The various components of the block diagram can be combined, added, or omitted according to the specifications of the actually implemented mobile terminal 600. That is, as needed, two or more components can be merged into one component, or one component can be divided into two or more components. Furthermore, the functions performed in each block are used to illustrate embodiments of the present invention, and their specific actions or devices do not limit the scope of the present invention.

[0195] Figure 6 yes Figure 1 Internal block diagram of the server.

[0200] On the other hand, when receiving dialogue content information based on dialogue content input from the image display device 100 or mobile terminal 600, the processor 570 in the server 500 updates the dialogue content information and provides the updated chat dialogue content to the image display device 100 or mobile terminal 600.

[0201] Figure 7 This is a flowchart illustrating an example of an operation method of an image display device according to an embodiment of the present invention. Figures 8a to 20b It is used for explanation Figure 7 A diagram illustrating the action method.

[0202] Referring to the accompanying drawings, the signal processing device 170 within the image display device 100 is controlled to determine whether there is an input for executing a broadcast chat application based on a signal from the remote control device 200 (S710), and if there is an input for executing a broadcast chat application, to display a broadcast image and a plurality of broadcast channel thumbnails (S715).

[0203] For example, such as Figure 8a As shown, the signal processing device 170 within the image display device 100 can be controlled to display the broadcast image 800 of the first channel.

[0204] At this time, the broadcast image 800 of the first channel may be a broadcast image corresponding to a broadcast signal received by the tuner 110 in the image receiving unit 105 or a broadcast signal received by the external device interface unit 130 such as the HDMI terminal.

[0205] Alternatively, the broadcast image 800 of the first channel may be a streaming media-based broadcast image received via the network interface unit 135.

[0206] On the other hand, the signal processing device 170 within the image display device 100 can receive application display input based on specific key movements or cursor movements within the remote control device 200.

[0207] The signal processing unit 170 within the image display device 100 can be controlled to, when receiving application display input, such as Figure 8b As shown, along with the broadcast image 800, an application list 810 including a plurality of applications is displayed.

[0208] At this point, the application list 810 may include the broadcast chat application 735.

[0209] On the other hand, the signal processing device 170 within the image display device 100 can receive input from the broadcast chat application based on specific key movements or cursor movements within the remote control device 200.

[0210] For example, such as Figure 8b As shown, when the broadcast chat application 735 in the application list 810 is selected based on a specific key action within the remote control device 200 or the action of the cursor 205, such as Figure 8c As shown, the signal processing device 170 within the image display device 100 can be controlled to display a broadcast image 800 and a plurality of broadcast channel thumbnails 820.

[0211] The plurality of broadcast channel thumbnails 820 includes thumbnails of broadcast channels received from tuner 110 and thumbnails of broadcast channels received from external device interface section 130 such as external input terminal.

[0212] On the other hand, the plurality of broadcast channel thumbnails 820 may also include thumbnails of broadcast channels received from the network interface unit 135.

[0213] On the other hand, a portion 824 of the plurality of broadcast channel thumbnails 820 may include a broadcast video image 824a, an object 742 representing a chat window, and audience number information 744.

[0214] Figure 8c Five broadcast channel thumbnails 821, 823, 824, 825, and 826 are shown as a plurality of broadcast channel thumbnails 820. Each of the broadcast channel thumbnails 821, 823, 824, 825, and 826 includes a broadcast video image, an object representing a chat window, and audience number information, respectively.

[0215] As described above, by displaying an object representing the chat window, it is easy to identify chat conversation content that can be provided related to the corresponding broadcast image when a specific broadcast channel thumbnail is selected.

[0216] On the other hand, by displaying audience count information, it is easy to identify the audience attention level of the corresponding broadcast.

[0217] Figure 8c Of the five broadcast channel thumbnails 821, 823, 824, 825, and 826, the third broadcast channel thumbnail 824 can be a thumbnail corresponding to the channel of the broadcast signal received from the tuner 110. Of the five broadcast channel thumbnails 821, 823, 824, 825, and 826, the fourth broadcast channel thumbnail 825 and the fifth broadcast channel thumbnail 826 can be thumbnails corresponding to the channel of the broadcast signal received from the external device interface section 130.

[0218] Next, the signal processing device 170 within the image display device 100 is controlled to determine whether there is a specific channel selection input based on the signal from the remote control device 200 (S720), and if there is a specific channel selection input, to display a chat window that includes the broadcast image of the corresponding channel and the chat dialogue content of the corresponding broadcast image (S725).

[0219] On the other hand, when no specific channel selection input is received, the signal processing device 170 within the image display device 100 controls the device to determine whether a subscription reservation for a specific channel's broadcast program is set (S721). If a subscription reservation for a specific channel's broadcast program is set, the device receives a notification at the corresponding broadcast program's broadcast time (S723) and displays a chat window that includes the broadcast image of the corresponding broadcast program and the chat dialogue content of the corresponding broadcast image.

[0220] On the other hand, the signal processing device 170 within the image display device 100 is controlled to transmit the input dialogue content to the server 500 when the broadcast image and chat dialogue content are displayed, based on the input dialogue content from the remote control device 200. It can be controlled to highlight the input dialogue content in the chat window (S735).

[0221] Therefore, by connecting to the server 500 that provides chat conversation content 750, chat conversation content can be entered and displayed simultaneously while displaying the broadcast image 830 corresponding to the selected channel from multiple broadcast channels. Furthermore, the selection of broadcast channels and chat conversation content 750 can be conveniently performed via the multiple broadcast channel thumbnails 820.

[0222] On the other hand, such as Figure 8c As shown, when multiple broadcast channel thumbnails 820 are displayed, and the second channel's broadcast channel thumbnail 824 is selected based on a specific key action or cursor 205 action within the remote control device 200, the signal processing device 170 within the image display device 100 controls the receiving unit 105 to receive the broadcast image 830 corresponding to the selected thumbnail from the image receiving unit 105, connect to the server 500 via the network interface unit 135, receive the chat dialogue content 750 corresponding to the broadcast image 830, and synchronize the broadcast image 830 and the chat dialogue content 750, such as... Figure 8d As shown, chat conversation content 750 is overlaid on broadcast image 800.

[0223] To synchronize the broadcast image 830 and the chat conversation content 750, the signal processing device 170 can synchronize the time information of the broadcast image 830 received from the image receiving unit 105 with the time information of the chat conversation content 750 received from the server 500 from the interface unit 135. This allows users to share chat conversation content with other users while viewing the same broadcast image 830.

[0224] On the other hand, such as Figure 8b As shown, the signal processing device 170 can be controlled to synchronize the broadcast image 830 received from the image receiving unit 105 with the chat conversation content 750 received from the server 500 from the interface unit 135 when the broadcast chat application 810 is executed. Figure 8d As shown, the chat conversation content 750 is overlaid on the broadcast image 830. Therefore, both the broadcast image 830 and the chat conversation content 750 can be viewed simultaneously.

[0225] Figure 9a The example shows an overlay of the broadcast image 830 and chat content 750 from Channel 2 at the first point in time. Figure 9bAn example is shown where the broadcast image 832 and chat content 750, 752 of the second channel are overlaid at a second time point after the first time point.

[0226] Server 500 receives chat content from a plurality of image display devices or a plurality of mobile terminals and can transmit the chat content to each of the plurality of image display devices or a plurality of mobile terminals.

[0227] Therefore, the amount of chat content displayed at the second time point after the first time point is greater than the amount of chat content displayed at the first time point.

[0228] On the other hand, in order to ensure the visibility of the chat content, as shown in the figure, the signal processing device 170 can be controlled to display the newly updated chat content at the upper right of the screen.

[0229] Figure 9b The example shows the existing chat content 750 moving downwards, and the new chat content 752 positioned at the top right.

[0230] On the other hand, the signal processing device 170 can be controlled to set a second interval larger than the first interval and display subsequent chat dialogue content in order to ensure the visibility of the chat dialogue content when the interval of the chat dialogue content received from the server 500 is within the first interval.

[0231] On the other hand, the signal processing device 170 is controlled to, when executing the broadcast chat application 810, such as Figure 10a As shown, broadcast image 800b and multiple broadcast channel thumbnails 820 are displayed simultaneously.

[0232] At this time, with Figure 10a In contrast, the signal processing device 170 can be controlled to display the chat content of the first channel corresponding to the broadcast image 800b of the first channel.

[0233] On the other hand, it can be controlled such that, while displaying the broadcast image 800b and chat content of the first channel, based on a signal from the remote control device 200, if a chat window object within the thumbnail of the second channel is selected from among the plurality of broadcast channel thumbnails 820, the chat content of the second channel is displayed on the broadcast image 800b of the first channel. This allows for convenient provision of chat content from other channels.

[0234] On the other hand, such as Figure 10aAs shown, when broadcast image 800b and multiple broadcast channel thumbnails 820 are displayed together, based on the signal from remote control device 200, if the first thumbnail 824 corresponding to the second channel is focused among the multiple broadcast channel thumbnails 820, the signal processing device 170 can be controlled to display a preview item 760 of the chat dialogue content corresponding to the first thumbnail 824.

[0235] Furthermore, when the signal selection preview item 760 is based on the remote control device 200, the signal processing device 170 can be controlled to display a preview screen (not shown) of the chat conversation content of the second channel.

[0236] Specifically, when the signal selection preview item 760 is based on the remote control device 200, the signal processing device 170 can be controlled to display a preview screen (not shown) of the chat conversation content of the two channels while the broadcast image 800b of the first channel, which is not the second channel, is being displayed. This allows for convenient access to chat conversation content from other channels not currently displayed, thus guiding channel switching.

[0237] On the other hand, when broadcast image 800b and a plurality of broadcast channel thumbnails 820 are displayed together, and based on the signal from remote control device 200, the signal processing device 170 can control the display to show the most recommended or most preferred chat content corresponding to the first thumbnail in the chat conversation content corresponding to the first thumbnail, rather than... Figure 10a The preview item 760. This allows for easy access to the most recommended or preferred chat content from followed channels, guiding users to switch channels.

[0238] On the other hand, such as Figure 10a As shown, when broadcast image 800b and a plurality of broadcast channel thumbnails 820 are displayed together, and the signal processing device 170 selects the first thumbnail 824 corresponding to the second channel among the plurality of broadcast channel thumbnails 820 based on the signal selection of the remote control device 200, the signal processing device 170 can control it to, as follows: Figure 10b As shown, the broadcast image 830 and chat conversation content 750 of the second channel are displayed overlaid.

[0239] Figure 11a An example is shown where the broadcast image 830 and chat conversation content 750 of the second channel are overlaid at the first time point. Figure 11b An example is shown where a broadcast image 832 and chat dialogue content 750, 752 from the second channel are overlaid at a second time point after the first time point. Figure 11cAn example is shown where a broadcast image 834 and chat dialogue content 750, 752, and 754 of the second channel are overlaid at a third time point after the second time point.

[0240] Reference Figures 11a to 11c The chat content 750 can correspond to the chat content entered based on the first account, the second chat content 752 can correspond to the chat content entered based on the second account, and the third chat content 754 can correspond to the chat content entered based on the account (ID) of the image display device 100.

[0241] The signal processing device 170 can be controlled to transmit the input dialogue content to the server 500 based on the signal input dialogue content from the remote control device 200, and the input dialogue content is highlighted in the chat window.

[0242] Figure 11c The third chat dialogue content 754 is shown as being highlighted at a different size than the other dialogue contents 750 and 752. This allows for the input and display of dialogue content while broadcast images and chat dialogue content are displayed together.

[0243] Figure 12a The example shows the broadcast image 834 and chat dialogue content 750, 752, 754 overlapping. Figure 12b The example shows that the number of likes or recommendations in the first chat conversation (750) increased by 786.

[0244] Referring to the accompanying drawings, the signal processing device 170 is controlled to transmit the preference or recommendation information of the first chat conversation 750 to the server 500 when a preferred item or recommendation item 783 of the first chat conversation 750 is selected based on a plurality of chat conversation contents 750, 752, 754 displayed by the remote control device 200. Figure 12b As shown, it can be controlled to display the increased number of likes or recommendations of the first chat conversation content 750.

[0245] exist Figure 12a When the number of likes or recommendations in the first chat conversation 750 is displayed as "1", and the likes or recommendations in the first chat conversation 750 are selected, the signal processing device 170 can control the selection to, for example, Figure 12b As shown, the number of likes or recommendations displayed in the first chat conversation 750 has increased to "2". Therefore, while performing likes or recommendations based on chat conversation content from other accounts, the number of likes or recommendations can be provided.

[0246] Figure 13aAn example is shown where a broadcast image 800 and multiple broadcast channel thumbnails 856 aligned vertically are displayed together.

[0247] Referring to the accompanying drawings, the signal processing device 170 can be controlled to, based on signals from the remote control device 200, such as Figure 13a As shown, the broadcast image 800 of the first channel and the thumbnails 856 of multiple broadcast channels aligned vertically are displayed together.

[0248] Multiple broadcast channel thumbnails 856 are aligned vertically, with one of the thumbnails being focused and displayed at its maximum size.

[0249] On the other hand, a portion of the plurality of broadcast channel thumbnails 856 may include broadcast video images, objects representing chat windows, and audience number information.

[0250] On the other hand, when the first thumbnail 856a is focused among a plurality of broadcast channel thumbnails 856, and the up or down arrow key of the remote control device 200 is activated, the signal processing device 170 can be controlled to, based on the signal from the remote control device 200, such as Figure 13b As shown, the first thumbnail 856a moves downwards, and the second thumbnail 856b moves towards the central area and is focused on.

[0251] On the other hand, it can be controlled such that, when focusing on the first thumbnail 856a among a plurality of broadcast channel thumbnails 856, upon receiving a channel up or channel down signal from the remote control device 200, the focus 856b moves to a second thumbnail located above or below the first thumbnail 856a.

[0252] On the other hand, the signal processing device 170 can be controlled to, for example Figure 13a As shown, based on a signal from the remote control device 200, while displaying a broadcast image 800 of the first channel and a plurality of broadcast channel thumbnails 856 aligned vertically, when focusing on the second thumbnail 856b corresponding to the second channel among the plurality of broadcast channel thumbnails 856, [the signal is displayed]. Figure 10a Similarly, the chat preview item 760 can be controlled to display the chat conversation content corresponding to the second channel in the preview screen (not shown) when the chat preview item 760 is selected.

[0253] On the other hand, the signal processing device 170 can be controlled to display chat content corresponding to the first channel on a preview screen (not shown) when focusing on the first thumbnail 856a of the first channel among the plurality of broadcast channel thumbnails 856, and can also be controlled to display chat content corresponding to the second channel on a preview screen (not shown) when focusing on the second thumbnail 856b of the second channel among the plurality of broadcast channel thumbnails 856. Thus, a preview of the chat content can be conveniently provided depending on the focus movement.

[0254] Figure 13b When selecting the second thumbnail 856b corresponding to the second channel from the plurality of broadcast channel thumbnails 856 shown, the signal processing device 170 can control it to, as follows: Figure 13c As shown, the broadcast image 830 of the second channel and the chat dialogue content 750b corresponding to the second channel are displayed.

[0255] On the other hand, the signal processing device 170 can be controlled to, for example Figure 13c As shown, in addition to the broadcast image 830 of the second channel and the chat dialogue content 750b corresponding to the second channel, a plurality of broadcast channel thumbnails 856 can also be displayed.

[0256] On the other hand, the signal processing device 170 can be controlled to display an indicator for menu guidance based on a signal from the remote control device 200.

[0257] For example, when the cursor of the remote control device 200 moves to the right end of the display 180, the signal processing device 170 can be controlled to display an indicator 905 for hiding the menu.

[0258] Furthermore, when the indicator 905 used for menu guidance is focused or selected based on a signal from the remote control device 200, the signal processing device 170 controls it to, as... Figure 14a As shown, menu 900 includes chat input item 960.

[0259] Figure 14a An example is shown where, while broadcast image 834 and chat dialogue content are displayed, menu 900, including chat input item 960, is displayed.

[0260] Referring to the attached diagram, menu 900 includes configuration file item 910, product item 920, music item 930, review item 940, PIP item 950, chat input item 960, and settings item 970.

[0261] When selecting an item 920 from the menu 900 based on a signal from the remote control device 200, the signal processing device 170 can control it to, for example, Figure 14bAs shown, a product catalog screen 1400 displays product items related to the broadcast image.

[0262] At this time, the signal processing device 170 can be controlled to display the product catalog screen 1400 instead of the broadcast image 834, while still displaying the chat dialogue content 1450. This allows product items related to the broadcast image to be provided.

[0263] Figure 14c This example shows the first item 1414 in the product catalog screen 1400.

[0264] Referring to the accompanying drawings, the signal processing device 170 can be controlled to focus on the first product item 1414 among a plurality of product items in the product catalog screen 1400 based on a signal from the remote control device 200.

[0265] On the other hand, when focusing on or selecting the first item 1414 among a plurality of items, the signal processing device 170 can be controlled to display a screen related to the purchase of the first item 1414.

[0266] Figure 15a An example is shown where a menu 900 with multiple items is displayed while broadcast image 834 and chat dialogue content are displayed.

[0267] Based on the configuration file item 910 within the signal selection menu 900 from the remote control device 200, the signal processing device 170 can be controlled as follows: Figure 15b As shown, screen 1500 displays account settings or a configuration file containing account information for setting up a configuration file.

[0268] Figure 15b The configuration file screen 1500 can include multiple account information 1503, 1507.

[0269] At this time, the signal processing device 170 can be controlled to display the configuration file screen 1500 instead of the broadcast image 834, while still displaying the chat dialogue content 1550.

[0270] Figure 16a An example is shown where a menu 900 with multiple items is displayed while broadcast image 834 and chat dialogue content are displayed.

[0271] In the case of music item 930 within the signal selection menu 900 from the remote control device 200, the signal processing device 170 can be controlled to, for example, Figure 16b As shown, a music catalog screen 1600 displays a music catalog related to the broadcast image 834.

[0272] Figure 16bThe music catalog screen 1600 may include: a first list 1620, which includes a plurality of music catalogs 1622, 1624, and 1626 associated with the broadcast image 834; and a second list 1610, which includes the previous music catalog 1603.

[0273] At this time, the signal processing device 170 can be controlled to display the music catalog screen 1600 instead of the broadcast image 834, while still displaying the chat dialogue content 1450.

[0274] Figure 16c An example is shown where a menu 900 with multiple items is displayed while broadcast image 834 and chat dialogue content are displayed.

[0275] In the case of a re-view item 940 within the signal selection menu 900 from the remote control device 200, the signal processing device 170 can be controlled to, for example, Figure 16d As shown, the review catalog screen 1640 displays a review catalog related to broadcast image 834.

[0276] Figure 16d The review of the catalog screen 1640 may include broadcast image 834 and review of the catalog 1642, 1644, 1646 at different times.

[0277] At this time, the signal processing device 170 can be controlled to display the review catalog screen 1640 instead of the broadcast image 834, while still displaying the chat conversation content 1450.

[0278] Figure 17a An example is shown where a menu 900 with multiple items is displayed while broadcast image 834 and chat dialogue content are displayed.

[0279] When based on the PIP item 950 within the signal selection menu 900 from the remote control device 200, the signal processing device 170 can be controlled to, for example, Figure 17b As shown, the chat dialogue content 1450 is displayed on the broadcast image 834 based on PIP input separation, and the chat dialogue content 1450 is displayed separately from the broadcast image in a first area. This improves the visibility of the chat dialogue content 1450.

[0280] Specifically, the signal processing device 170 can be controlled to reduce the screen size of the selected broadcast image 834 based on the PIP item 950, separate the reduced-size broadcast image 1710 from the chat dialogue content 1450, and display the broadcast image 1710 and the chat dialogue content 1450 separately.

[0281] Figure 17cThis example illustrates the display of broadcast image 1710 and chat conversation content 1450 in PIP mode, with... Figure 17b In contrast, it is illustrated by displaying a plurality of thumbnails 856 arranged in the vertical direction within the broadcast image 1710.

[0282] The signal processing device 170 can be controlled to display the broadcast image 1710, which includes a plurality of thumbnails 856, separately from the chat conversation content 1450 based on the selection of PIP item 950. This improves the visibility of the chat conversation content 1450.

[0283] On the other hand, when the broadcast image 1710, including a plurality of thumbnails 856, and the chat content 1450 are displayed separately, if the first thumbnail is focused based on a remote control signal, the signal processing device 170 can be controlled to display the chat content of the channel corresponding to the first thumbnail in the first area. This allows for convenient provision of chat content from other channels.

[0284] Figure 18a An example is shown where a menu 900 with multiple items is displayed while broadcast image 834 and chat dialogue content are displayed.

[0285] In the case of chat input item 960 within the signal selection menu 900 from the remote control device 200, the signal processing device 170 can be controlled to, for example, Figure 18b As shown, the keyboard display window 1810 and the text input window 1815 are displayed.

[0286] When text is selected in the keyboard display window 1810 based on a signal from the remote control device 200, the signal processing device 170 can control the text to be displayed in the text input window 1815.

[0287] Furthermore, the signal processing device 170 can be controlled to transmit the input text to the server 500 when the transmission item for transmitting text input to the text input window 1815 is selected, and the input text transmitted to the server 500 is displayed as dialogue content in the chat window. Thus, when dialogue content is input based on signals from the remote control device 200, dialogue content can be conveniently input and displayed.

[0288] In the case of chat input item 960 within the signal selection menu 900 from the remote control device 200, the signal processing device 170 can be controlled to, for example, Figure 18b As shown, in addition to the keyboard display window 1810 and the text input window 1815, the mobile terminal input item 1830 is also displayed.

[0289] Figure 18cThis illustrates how the keyboard display window 1810 disappears when the input item 1830 on the mobile terminal is focused on or selected by the remote control device 200.

[0290] The signal processing device 170 can be controlled to, for example Figure 18b As shown, when the keyboard display window 1810, text input window 1815, and mobile terminal input item 1830 are displayed, the keyboard display window 1810 disappears when the mobile terminal input item 1830 is focused on or selected by the remote control device 200.

[0291] On the other hand, the signal processing device 170 can be controlled to, when the mobile terminal input item 1830 is focused or selected by the remote control device 200, such as Figure 18d As shown, image 1840 displays the code used to install a chat application on mobile terminal 600.

[0292] For example, when the mobile terminal input item 1830 is focused or selected by the remote control device 200, the signal processing device 170 can be controlled to wirelessly connect to the preset mobile terminal 600 to confirm whether a chat application is installed. If not installed, the code image 1840 for installing the chat application is displayed.

[0293] On the other hand, the signal processing device 170 can also be controlled to not display if a chat application is confirmed to be installed on the mobile terminal 600. Figure 18d Image 1840.

[0294] The mobile terminal 600 can be controlled to display a chat input window based on the installed or executed chat application, and transmit the input text to the server 500. The input text transmitted to the server 500 is displayed as the dialogue content in the chat window.

[0295] Therefore, the text input via the mobile terminal 600 can be displayed on the image display device 100.

[0296] Figure 19a An example is shown where, while broadcast image 834 and chat conversation content 1450 are displayed, an object for continuing or ending the chat conversation content 1450 is displayed based on a signal from remote control device 200.

[0297] Referring to the accompanying drawings, the signal processing device 170 can be controlled to display an object 1910 for continuing to display or ending the chat conversation content 1450 based on a signal from the remote control device 200, while the broadcast image 834 and chat conversation content 1450 are displayed.

[0298] Object 1910 may include a continue display option or an end option for the chat conversation content 1450.

[0299] On the other hand, as shown in the figure, object 1910 may also include shared item 1920.

[0300] In the case of a shared item 1920 within the signal selection object 1910 from the remote control device 200, the signal processing device 170 can perform image capture or motion image capture of the broadcast image 834.

[0301] Figure 19b This is a diagram showing an image capture or a dynamic image capture of broadcast image 834.

[0302] Referring to the accompanying drawings, when selecting a shared item 1920 within object 1910 based on a signal from remote control device 200, signal processing device 170 can be controlled to display an object 1925 indicating the object being captured while performing image capture or motion image capture of broadcast image 834.

[0303] At this point, the captured images or moving images may also include broadcast images and chat conversation content.

[0304] The signal processing device 170 can be controlled to, after acquisition is completed, such as Figure 19c That way, the captured image or moving image 1930 is displayed, along with the recapture item 1932 and the transmission item 1934.

[0305] When recapture option 1932 is selected, signal processing device 170 can perform image capture or motion image capture of broadcast image 834 again.

[0306] When transmission item 1934 is selected, the signal processing device 170 can be controlled to transmit the captured image or moving image to the server 500.

[0307] That is, the signal processing device 170 can be controlled to transmit the captured image or moving image to the server 500 for sharing in the chat window displaying the chat conversation content 1450.

[0308] Figure 19d An example is shown where a captured image or moving image is displayed on the upper right side of the image display device 100 and on the lower side of the mobile terminal 600.

[0309] The signal processing device 170 can be controlled to display the captured shared image or moving image 1942 on the upper right side to ensure visibility.

[0310] That is, the signal processing device 170 of the image display device 100 can be controlled to display the latest conversation content on the upper right side, unlike the mobile terminal 600 displayed at the lower end, to ensure visibility.

[0311] Figure 20a An example is shown where a menu 900 with multiple items is displayed while broadcast image 834 and chat dialogue content are displayed.

[0312] Based on the setting item 970 within the signal selection menu 900 from the remote control device 200, the signal processing device 170 can be controlled to, for example, Figure 20b As shown, the settings screen 2000 displays a plurality of settings options 2010, 2015, and 2017.

[0313] At this time, the signal processing device 170 can be controlled to display the setting screen 2000 instead of the broadcast image 834, while still displaying the chat dialogue content 1450.

[0314] On the other hand, the server 500 can control the separation of chat windows and the execution of multiple chat windows based on the number of image display devices 100 or mobile terminals 600 connected to chat windows associated with the specified broadcast image.

[0315] Specifically, if the number of image display devices 100 or mobile terminals 600 connected to chat windows associated with a specified broadcast image exceeds a baseline value, the server 500 can generate and provide new chat windows. This prevents overload of connections for specific chat windows.

[0316] For example, server 500 can be controlled such that if the number of image display devices 100 or mobile terminals 600 connected to the chat window related to the specified broadcast image is 1999 and the baseline value is set to 1000, 1000 can be connected in the first chat window and 999 in the second chat window.

[0317] On the other hand, the baseline value can be changed; for example, it can be set to 667 instead of 1000.

[0318] For example, server 500 can be controlled such that if the number of image display devices 100 or mobile terminals 600 connected to the chat window related to the specified broadcast image is 1999 and the baseline value is set to 667, 667 can be connected in the first chat window, 667 in the second chat window, and 665 in the third chat window.

[0319] On the other hand, server 500 can be controlled to share conversations with a high number of likes or recommendations in the first chat window among multiple chat windows to other chat windows.

[0320] For example, the image display device 100 can be controlled to receive and display chat conversation content from the server 500 while the first chat window is connected, and to receive chat conversation content from the server 500 that has a base number of likes or recommendations, and to display it at any time at a specific position within the first chat window. This allows for the sharing of chat conversation content with a large number of likes or recommendations.

[0321] On the other hand, when the amount of dialogue content input from the outside is greater than a certain amount, the image display device 100 can change the display speed of the chat dialogue content.

[0322] For example, the image display device 100 can be controlled to display one chat message every three seconds when the number of externally inputted chat messages is greater than a certain threshold, and it can also be controlled to display one chat message every five seconds when the number of externally inputted chat messages is less than the threshold. This improves the visibility of the chat messages.

[0323] On the other hand, the image display device 100 can be controlled to adjust the display speed of the chat conversation based on the on / off options in the chat settings screen. This allows for selective adjustment of the chat conversation display speed.

[0324] The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the specific embodiments described above. It will be apparent to those skilled in the art that various modifications can be made without departing from the spirit of the invention as claimed in the claims. Such modifications should not be understood separately from the technical concept or prospect of the present invention.
