Accordingly, the input list may include live TV and at least one external input (e.g., an input via an HDMI port).In the present disclosure, the simple term "input" may refer to not only an external input via an input port provided in the display device 100, but also an internal input, i.e., an input via a tuner 130 or 131. However, the term "input port" in the present disclosure may denote only an external input, but is not necessarily limited thereto.At least one external input may be connected to an external device via the input port. The input list may include only input ports connected to all input ports or devices and activated because the device is on, or may exclude inactive input ports not connected to or powered off from the input port. However, the present disclosure is not limited thereto.For example, in addition to the input port provided in the tuner 130 or 131 or the display device 100, a wirelessly connectable device may also be included in the input list according to the present disclosure and provided via the screen.FIG. 6( a) is a block diagram of a display device 100 according to another embodiment of the present disclosure, and FIG. 6( b) is a block diagram of another configuration between the second video processor 620 and the input port in FIG. 6( a).The display device 100 may be connected to an external device via cables because it has at least one input port, and may also be wirelessly connected to at least one external device.In the present disclosure, for convenience of explanation, the input through an input port will be described using, but is not limited to, an example of an HDMI input.In FIGS. 6( a) and 6( b), four input ports (HDMI1-HDMI4) are illustrated, but the number of input ports is not limited to four.Referring to FIGS. 6( a) and 6( b), the display device 100 and an external device for exchanging data may be connected via the HDMI connection supported by each input port.The display device 100 may include a memory and a processor. The processor may include a processing unit 600. According to an embodiment, the processor may also include a second video processor 620.Referring to FIG. 6( a), the processing unit 600 may include a first video processor 610 to process data received via an internal input, i.e., a tuner 130 or 131, and output the data via the display 180. The tuner shown in Fig. 6(a) may have the same configuration as the tuner 130 or 131 of Fig. 1.The processing unit 600 may receive data from an external device via an external input, i.e., an input port, process the received data, and output it via the display 180.In the present disclosure, the data received via each input may include video data, still image data, audio data, web page data, etc., but for convenience, video data will be described only as an example.In the present disclosure, "provision" may mean reproduction of video data, provision of a web service, execution of a web application, or operation of the display device 100 therefor. Moreover, "provision" may mean that the result of the above-described operation is output through the screen.The processing unit 600 may be implemented as a system on chip (SoC) and may correspond to, but is not limited to, the controller 170 of FIG. 1. According to an embodiment, the processing unit 600 may be divided into multiple modules.Taking the example of FIG. 6( a), the display device 100 may be configured to include a first video processor 610 and a second video processor 620 in the processing unit. According to an embodiment, the second video processor 620 may also be included in the processing unit 600. According to another embodiment, the first video processor 610, like the second video processor 620, may be located outside the processing unit 600.A video processor may process video data received via at least one input. When multiple video processors are integrated in the display device 100, each video processor may exclusively be responsible for the internal (tuner) and external (input port) inputs. Thus, the display device 100 can process and provide a plurality of video data simultaneously.In FIG. 6( a), the display device 100 is provided with two video processors 610 and 620 each associated with the tuner 130 and 131, respectively, and one input port, and can process and provide the video data received via each input simultaneously. If no video processor is assigned to tuner 130 or 131, the corresponding video processor may be assigned to an input port at this time.As shown in FIG. 6( a), the second video processor 620 may be sequentially connected to each input port in a predetermined order unless the user requests selection of a particular input port. After the connection, it can process the data received via the input port. The connection can only exist for a fixed time. After this time has elapsed, the remaining inputs can be connected to the next higher input port.In the present disclosure, the first video processor 610 is provided in the processing unit 600, and the second processor 620 is provided in addition to, but not limited to, the processing unit 600.As shown in FIG. 6( b), the second video processor 620 may sequentially switch the input ports. For example, if an input port is present or one input port of multiple input ports is enabled, the second video processor 620 may process the data received via that input port at 60 frames / s. On the other hand, if multiple input ports are enabled (e.g., four), the second video processor 620 may process the signals received via each input port by continuously switching at a rate of 15 frames / s. In the latter case, for example, if the second video processor 620 can process 60 frames per second, it can process four input signals each having 15 frames by switching four times per second. The display device 100 can continuously switch by opening and closing the switch for the four input ports shown in FIG. 6( b), thus providing the data for the four input ports as if they were reproduced simultaneously. However, the present disclosure is not limited to the above numerical values.According to another embodiment, as many as the number of input ports may be assigned to the second video processor.In other words, the number of video processors in the display device 100 may be equal to or less than the number of input ports, but is not limited thereto.Referring back to FIG. 6( a), the first video processor 610 may be incorporated in the processing unit 600, and the second processor 620 may be provided outside the processing unit 600.The first video processor 610 may process video data received via an input (either dedicated to the internal input or any external input), and the second video processor 620 may process data received via an input other than the external input or the input dedicated to the first video processor 610 (which may also include a tuner).When the first video processor 610 is to process the video data received via the tuner 130 or 131, the second video processor 620 may be to process the video data received via an arbitrary input port (one of HDMI 1 to HDMI 4) simultaneously or at different times.Alternatively, if the first video processor 610 is to process video data received via one input port (e.g., HDMI1), the second video processor 620 may be to process video data received via another input port (one of HDMI2 to HDMI4), simultaneously or at different times.FIG. 7 is a flowchart illustrating an operation method of a display device 100 according to an embodiment of the present disclosure.FIG. 8 is a diagram illustrating a user interface related to the operation of the display device 100 of FIG. 7.FIG. 16 is a diagram illustrating a video data processing operation corresponding to the input port in the display device 100 according to an embodiment of the present disclosure.Referring to FIG. 7, the display device 100 (or the processor) may receive a user input (S 101).The display device 100 may provide an input list (S 103).The display device 100 may display (or provide) data received via an input that matches (or maps) at least one area included in the input list determined according to a predefined order (S 105).In step S 101, the user input may be received via the remote control device 200.According to an embodiment, the user input in step S 101 may be received by a touch input via a mobile terminal (smartphone, wearable, etc.) connected to the display device 100 or on which a remote control application is installed, a voice input via an AI speaker, a gesture, or biometric input via an image sensor installed on the display device 100 or in a predetermined space, etc.According to a further embodiment, the user input can be received in a form in which the above-mentioned methods are combined accordingly.In step S 103, the display device 100 may provide an input list based on the user input received in step S 101, but is not necessarily limited thereto.According to an embodiment, the display device 100 may configure and provide (or output) the input list of step S 103 even when the user input is not received in step S 101 if a predetermined condition is satisfied.The predetermined condition may be determined and automatically set based on, for example, a user, a time, a location, and content provided by the display device 100, or a combination thereof, and the set condition content may be provided to the user via the screen for convenience.As a prerequisite, the user may be identified by referring to at least one method of login information, an image captured by an image sensor, a password input, etc.As a condition, for example, when a predefined determined time is reached, the input list may be configured to provide comfort to the user even without a separate input of the user.As a condition, when a display device 100 is movable as in FIG. 5 and entry / exit of a certain space is correspondingly marked, an entry list may be set to provide convenience to the user even without separate input of the user.Other conditions can be explained in the same manner. As to the setting, storage, etc. of these conditions, reference is made to Fig. 16. For example, FIG. 16( a) may be regarded as a default setting, and a look-up table (LUT) or an allocation table such as FIGS. 16( b) to 16( d) may be personalized or created and stored as needed.FIG. 16( a) may illustrate a basic reproduction order (live TV screen - HDMI1 screen - HDMI2 screen - HDMI3 screen - HDMI4 screen - live TV screen). However, the present disclosure is not limited thereto. According to an embodiment, the display device 100 may process the channels of the first and last live TV screens to be different from each other, and may recommend channels whose characteristics or characteristics of the contents provided by each channel or the respective channels are related to each other, but is not limited thereto.In 16( b), a table taking the user and the time into account as conditions is exemplarily shown, in 16( c), a table taking the user and the space into account as conditions is exemplarily shown, in 16( d), a table taking the user, the time, and the space into account as conditions is exemplarily shown, and in 16( e), a table taking the horizontal mode or the vertical mode into account as conditions in the case where the display device 100 can be operated in the horizontal mode or the vertical mode as in FIG. 5.The table illustrated in FIG. 16 may be stored in the integrated database of the display device 100 or in a database (for example, in the form of a cloud) connected to a server (not illustrated).Referring to FIG. 7, a screen-provided user interface related to the operation of the display device 100 of FIG. 8 will be described.FIG. 8( a) shows an entry list 810 on a home screen dashboard, and FIG. 8( b) shows an entry list 820 displayed when a home screen dashboard and an application list are present. However, the present disclosure is not limited to the configuration of a user interface having the entry list illustrated in FIG. 8.FIG. 8 shows an embodiment in which, for simplicity, an entry list (810, 820) is provided on a home screen dashboard. However, the input list may be provided on an application list or provided via an input list created separately instead of the home screen dashboard or the application list.The input list 810 illustrated in FIG. 8( a) provides areas for providing information to all input ports (live TV, HDMI 1, HDMI 2, and HDMI 3) equipped to the display device 100, and data received via a device connected to the corresponding input port may be provided in each area.The input list in FIG. 8 may include areas including only information on some of the input ports (live TV, HDMI 1, and HDMI 2) of the display device 100. Each region contains data received via a device connected to the corresponding input port. In the case of Fig. 8(b), the input port (HDMI3) may be excluded from the input list because it is in an inactive state, e.g. when no device is connected or the connected device is switched off.According to an embodiment, when there are sufficient resources, that is, when the number of video processors is equal to or larger than the number of input ports provided in the display device 100, video data received via the respective input ports can be reproduced simultaneously in each area included in the input list.According to an embodiment, even if there are sufficient resources as described above, the display device 100 may control not to activate all the areas included in the input list, i.e., to reproduce the video data received via the respective input ports simultaneously, but to activate only some areas and then to reproduce the remaining areas one after another in a predefined order.The display device 100 may be controlled to provide a still image of data to be received and reproduced via an input associated with the corresponding area, or a representative image representing the corresponding input for an area other than at least one area determined according to a predefined order.According to an embodiment, when the resources are insufficient, that is, when the number of video processors is less than the number of input ports provided in the display device 100, only some areas may be selected from all areas included in the input list. In some areas, video data received via the associated input may be reproduced, and in the remaining areas, an empty screen (or black screen) or a still screen image (or still image) of the video data to be provided later may be provided.According to an embodiment, when the display device 100 provides data received by an input associated with the next area, for example, according to satisfaction of the first condition described below for the previous order area, the output may be controlled by at least one of the first frame of the provided data, the last frame, the representative thumbnail of the corresponding data, the representative thumbnail representing the input associated with the corresponding area, and the still image for the scene in which the user input for the corresponding area has been performed.In the present disclosure, only some of the areas are activated, not all areas included in the input list. However, when the display device 100 has sufficient resources, precoding of the video data of the areas may be performed to reproduce them later. This makes it possible to avoid problems due to network conditions or other problems occurring later in the advance or to quickly detect problems such as network conditions at the corresponding input port.The input list shown in FIGS. 8( a) and 8( b) allocates a range to at least one input port. Each area reproduces and provides the video data received via at least one input port as described below. Each area may be associated with the playback order of the video data received via the corresponding input port. In the example of FIG. 8( a), in the input list, four areas are allocated to each input port, namely, the input ports Live TV, HDMI 1, HDMI 2, and HDMI 3, and video data received via the input ports HDMI 1, HDMI 3, and HDMI 3 may be reproduced in the order of Live TV, and vice versa.In this connection, when a user performs an operation such as touching and dragging, voice input, or gestures via a remote control device 200, an artificial intelligence speaker, or a connected smartphone, the display device 100 may control the desired area to be selected and shifted, deleted, or added in response thereto, and may also control reproduction of a particular input port to be excluded, stopped, stopped, or played back again.When the display device 100 in FIG. 6 is equipped with a number of video processors corresponding to the input ports, each area included in the input list in FIG. 8 may provide video data received via the corresponding input port.When video data is reproduced in an area corresponding to two or more input ports included in the input list, all audio data may be muted or only audio data may be controlled to be output for video data received and reproduced via an input port having the highest priority.According to an embodiment, when video data received via at least one input port included in the input list is provided, output control of audio data may be determined according to content provided via the main screen of the display device 100.In the input lists of FIGS. 8( a) and 8( b), input ports corresponding to contents currently provided via the main screen of the display device 100 or contents whose reproduction has been stopped may be excluded.According to another embodiment, in the entry list of FIGS. 8( a) and 8( b), video data of a medium or channel other than the content may be provided without being excluded when an input port corresponding to the content currently provided or stopped via the main screen of the display device 100 corresponds to a tuner and the display device 100 is equipped with a plurality of tuners.FIG. 9 is a flowchart illustrating an operation method of a display device 100 according to another embodiment of the present disclosure.FIG. 10 is a diagram illustrating a user interface related to the operation of the display device 100 of FIG. 9.Referring to FIG. 9, the display device 100 may receive a user input (S 201).The display device 100 may determine whether the user input is a request to change an input port (S 203).When the result of the judgment in step S 203 is a request to change the input port, the display device 100 may output the first screen (S 205).The display device 100 may determine whether the first condition is satisfied (S 207).When the result of the judgment in step S 207 is that the first condition is satisfied, the display device 100 may provide video data received via the input port corresponding to the input list and at least one area included in the input list in the corresponding area (S 209).The display device 100 may determine whether the second condition is satisfied (S 211).When the result of the judgment in step S 211 is that the second condition is satisfied, the display device 100 may output the second screen (S 213).Referring to FIG. 9, FIGS. 10( b) to 10( d) may be screens on which video data received via each input port included in the input list is reproduced. Figs. 10(b) to (d) may be screens displayed one after another.Meanwhile, FIG. 10( a) may illustrate a first screen displayed as in step S 205 because user input that is an input list request or a missed input that is not related to the content output via the display 180 has been input in step S 201 of FIG. 9. According to an embodiment, the first screen of FIG. 9 may be a "no signal" screen. According to another embodiment, the first screen may continue the previous screen, but in response to the user input, the information "no signal" is displayed in a dialog window or the like in a region of the screen.FIG. 10( b) may provide a live TV screen as a first priority input port that is included in the input list after the screen of FIG. 10( a) is provided.The display device 100 may control the provision of data received via an input, wherein video data is assigned to the next area in the predefined order among the areas included in the input list when the first condition is satisfied.FIG. 10( b) shows that the first condition is satisfied. The first condition may indicate a predefined time. This can be, for example, 3 seconds, 5 seconds, 10 seconds, 30 seconds, 1 minute, etc. and can be changed arbitrarily.Figure 10(c) may provide an HDMI1 screen as a second priority input port included in the input list after the screen of Figure 10(b).FIG. 10( d) may provide an HDMI2 screen as a third priority input port included in the input list after the provision of the screen of FIG. 10( c).FIG. 10( e) may illustrate a second screen displayed after the display of the screen in FIG. 10( d) as in step S 213. According to an embodiment, the second screen may be empty or black. According to another embodiment, the second screen may be the same as the screen shown in FIG. 10( a), or may be one of the screens shown in FIGS. 10( b) to 10( d).The second screen in FIG. 10( e) may be displayed when the second condition is satisfied. The second condition may indicate that there is no input port in the input list that is not being played back.Figs. 10(a) to 10(e) show the screen contents sequentially displayed on the screen of the display device 100. In FIG. 10, for convenience, the screen received through each input port is represented as a frame, but this is not limited thereto.The display device 100 displays the video data received through the input ports illustrated in FIGS. 10( b) to 10( d) on the screen, and can display various information in a screen area. The first information may be the input port identification information for receiving video data output through the corresponding screen. The second information may be a query as to whether to maintain the video data screen of the current input port. The third information may be the input port identification information of the next screen to be changed. The various information described above may be displayed in the form of a dialog window, etc. The display device 100 may immediately change to the screen of the desired input port, maintain the screen of the corresponding input port, or return to the previous reproduction screen, depending on the user selection, instead of performing the sequential reproduction.FIG. 11 is a flowchart illustrating an operation method of a display device 100 according to another embodiment of the present disclosure.FIG. 12 is a diagram illustrating a user interface related to the operation of the display device 100 of FIG. 11.FIGS. 11 and 12 describe a processing operation of the display device 100, particularly when at least one input port among the input ports included in the input list is disabled.In the present disclosure, the deactivation of an input port may refer to at least one of the following cases: when no device is connected to the corresponding input port, when a device is connected to the corresponding input port, but the device is turned off or cannot normally receive video data from the corresponding device due to other errors, or when normally received video data cannot be decoded or processed due to causes such as codec.Referring to FIG. 11, the display device 100 may determine whether the input port is in an inactive state (S 301).When the input port is in an inactive state as a result of the determination in step S 301, the display device 100 may issue an instruction for power-on control of the inactive input port (S 303). The instruction may be as shown in FIG. 10( d), but is not limited thereto.After providing the guidance message in step S 303, the display device 100 may determine whether the user has received a power-on request for the corresponding inactive input port device (S 305). The power-on request for the corresponding inactive input port device may be made by, for example, pressing the "OK" button of the remote control device 200, but is not limited thereto.As a result of the judgment in step S 305, when the display device 100 is not a power-on request for an inactive input port compatible device, for example, when a signal is received via the remote control device 200 in response to pressing a key other than the "Okay" key, the display device 100 may determine whether the input is an input in response to pressing the power-on key (S 307).When the display device 100 does not output an input as a result of the judgment in step S 307 in response to the pressing of the power button, the display device 100 may output an error message such as "Have pressed the wrong button" (S 317).On the other hand, if the display device 100 outputs an input in response to the depression of the power switch as a result of the judgment in step S 307 in response to the depression of the power switch, the display device 100 may provide an associated guidance message to identify whether the input is a power-off input for turning off the power supply of the display device or an input in response to the power supply of the inactive input port compatible device of the aforementioned step S 305 (S 309).After providing the guidance message in step S 309, the display device 100 may determine whether the input of the user via the remote control device 200 requests the display device 100 to be turned off (S 311).When the user's input via the remote control device 200 is a power-off request for the display device 100 as a result of the determination in step S 311, the display device 100 may turn off the power supply of the display device 100.On the other hand, when the user input via the remote control device 200 is not a power-off request for the display device 100 according to a result of the determination in step S 311, i.e., an input for turning on a device corresponding to an inactive input port in step S 305, the display device 100 may generate a device power-on control command and transmit it to the corresponding device (S 313). The same applies to the case where the "OK" key is pressed in step S 305.The display device 100 may output the video data of the corresponding input port (S 315) when the corresponding device is turned on after step S 313. The display device 100 may also determine whether the corresponding device is turned on, for example, based on receiving data via the corresponding input port.The display device 100 can execute the operations shown in Figs. 12(a) to 12(c) as shown in Figs. 10(a) to 10(c), and can refer to Fig. 9 as needed. FIG. 11 may thus be based on at least one or more of the steps illustrated in FIG. 9.When the result of the determination in step S 301 shows that at least one input port is in an inactive state, the display device 100 may provide a screen such as (d) in FIG. 12 and a guidance message from step S 330.The display device 100 may provide a screen as illustrated in FIG. 12( d) according to the result of the determination in step S 301, and when the inactive input port becomes active by at least one operation in steps S 305 to S 315, the display device 100 may receive video data from the device connected to the corresponding input port and provide it as illustrated in FIG. 12( e).According to an embodiment, the display device 100 may determine whether the inactive state of the corresponding input port is due to the absence of a connected external device by generating and transmitting a device power-on command between steps S 303 and S 305 (step S 313), and since the inactive input port may not necessarily be a connected but power-off external device but may not be a connected device, a simplified version of the command may be generated and transmitted that determines only the presence or absence of an external device connected to the corresponding input port compared to the device power-on command (step S 313).In the operations of FIGS. 12( d) and 12( e), the display device 100 may use a predetermined protocol to control the power supply of the device connected to the deactivated input port. In the present disclosure, HDMI-CEC (Consumer Electronics Control) is used as an example of the device power control protocol, but is not limited thereto.FIG. 13 is a flowchart illustrating an operation method of a display device 100 according to another embodiment of the present disclosure.FIG. 14 is a diagram illustrating a user interface related to the operation of the display device 100 of FIG. 13.FIG. 13 specifically illustrates a processing operation according to the present disclosure when the display device 100 supports a multi-view mode. The multi-view mode may denote a mode that provides different contents over at least two individual screen areas on one screen, as illustrated in FIG. 14( a).The display device 100 may control data received via an input associated with at least one area among the areas included in the input list in a predefined order to be reproduced via at least one display screen area of the full-screen or multi-view mode.When a user input is received (S 401), the display device 100 may determine the multi-view mode (S 403).When the display device 100 is in the multi-view mode, the display device 100 may provide video data received via each input port to each multi-view screen area (S 405).The display device 100 may provide video data of the input port in the multi-view mode through step S 405 but may determine whether a condition is satisfied (S 407).When the condition of the judgment result of step S 407 is satisfied, the display device 100 may provide video data corresponding to another input port (S 409).When at least one of the following applies: when the current playback mode of the display device 100 is a multi-view mode; when the multi-view mode is requested via a remote control device 200, etc.; when a plurality of viewers currently view the display device 100; when it is determined that the multi-view mode is preferred based on the history information of a user logged on to the display device 100; the display device 100 may execute the process after step S 405, i.e., provide an input list according to the present disclosure in the multi-view mode.Referring to FIG. 14, the display device 100 may output video data of the first input port (e.g., live TV) to the first screen region 1410 and output video data of the second input port (e.g., HDMI 4) to the second screen region 1420.The display device 100 may individually edit each screen area depending on whether the condition in step S 407 is satisfied. That is, the display device 100 may individually execute the process after step S 407 for the first screen region 1410 and the process after step S 407 for the second screen region 1420. The individual processes can be carried out simultaneously or successively. As shown in FIG. 14, due to the judgment in step S 407, the video data of the first input port is continuously output in the first screen region 1410, while the video data of the second input port in the second screen region 1420 may be changed to the video data of the third input port.The condition in step S 407 may correspond to either the first condition or the second condition described above in FIG. 9, but is not limited thereto.FIG. 15 is a drawing illustrating another user interface related to the operation of the display device 100 according to the present disclosure.As illustrated in FIGS. 10 and 12, the video data received via each input port in the display device 100 may be provided in the full-frame mode or the multi-view mode as illustrated in FIG. 14.Referring to FIG. 15, the display device 100 may provide video data received via one input port as a full screen, and simultaneously provide video data received via the remaining input ports in an area within the screen.Referring to FIG. 15(a), the display device 100 may automatically execute the dashboard 1520 and provide video data received via the remaining input ports to elements or areas of the dashboard 1520.Referring to FIG. 15(b), the display device 100 may associate a predetermined area within the screen with as many input ports as remaining, similarly to FIG. 15(a) described above, and provide the video data received via the remaining input ports to each associated area 1530, 1540, 1550.When a predetermined condition is satisfied, the display device 100 may shift the display of the corresponding input port provided over the entire screen to and continue to display in an area of the dashboard 1520 (see FIG. 15( a) ), or may shift to and continue to display in one of the assigned areas ( 1530 to 1550) (see FIG. 15( b)).
