Based on the display device 200 described above, the user may control the display device 200 to present different user interfaces through specific interactions. The user interface may be subdivided into various types according to the functions it specifically provides. For example, the user interface provided by the display device 200 may include a signal source interface for controlling switching of signal sources.

In the embodiment of the present application, the signal source generally refers to various resource servers, external devices, signal networks, and the like capable of providing a specific display screen for the display device 200. The display apparatus 200 may connect different devices, lines to connect different signal sources through the external device interface 240. As shown in fig. 5, for example, the external device interface 240 may be a coaxial cable interface provided on the display apparatus 200, and a user may connect the coaxial cable interface to a digital television signal line to receive a television live signal from the digital television signal line and play it on the display 260. For another example, the external device interface 24 may be an HDMI interface provided on the display apparatus 200, and the user may connect the HDMI interface to the game apparatus to obtain a game screen signal from the game apparatus and play it on the display 260.

Since a plurality of types of external device interfaces 240 may be provided on the display apparatus 200 and the number of each type of external device interfaces 240 may be also provided in plurality, the display apparatus 200 may be simultaneously connected to a plurality of signal sources. For example, the display apparatus 200 may be provided with an external device interface 240 such as a coaxial cable interface, an HDMI interface, a USB interface, and an AV interface. Each type of external device interface 240 may be connected to an external device or a signal line in the form of its prescribed interface. In order to enrich the media play content of the display device 200, two HDMI interfaces, i.e., an HDMI1 interface and an HDMI2 interface, may be provided on the display device 200.

Obviously, the external device interface 240 under the same type may also be connected to different types of signal sources. For example, the display device 200 connects to a game device through an HDMI1 interface to receive game screen data generated by the game device; the display device 200 is also connected to the digital tv set-top box through the HDMI2 interface to receive tv live signals through the set-top box.

It should be noted that the signal source of the display apparatus 200 is not limited to the above-mentioned connection form through the external device interface 240, and other types of connection forms may be supported. That is, in some embodiments, the display device 200 may also be connected to a signal source through the communicator 220. For example, a wireless network module may be built in the communicator 220, and the display device 200 may establish a screen-throwing connection with the communication terminal 300 through the wireless network module, so as to synchronously play the content displayed on the communication terminal 300, that is, the signal source of the display device 200 is the communication terminal 300 at this time. In addition, other devices or networks that establish connections with the display device 200 in specific communication manners including, but not limited to, wired networks, wireless networks, bluetooth, infrared, NFC, etc., may also be used as signal sources for the display device 200.

In order to enable the display device 200 to normally present the picture content in each signal source, the display device 200 generally plays only the audio/video data corresponding to one signal source in use, and plays the picture content of other signal sources by switching the signal sources. For example, when a user wants to watch a live tv, the signal source of the display device 200 may be set as a coaxial cable interface, so as to play a live tv signal delivered by the coaxial cable interface. And when the user wants to play the game, the signal source of the display device 200 may be controlled to be the HDMI1 interface, thereby playing the game picture signal transferred by the game device.

The signal source interface can provide operations such as signal source selection, switching and the like for a user. Thus, a plurality of interface options may be provided in the signal source interface. For example, as shown in fig. 6, a live tv (coaxial cable interface) option, an HDMI1 option, an HDMI2 option, a USB option, a screen-cast option, and the like may be included in the signal source interface. The user can control the focus cursor in the signal source interface to move among the plurality of interface options through the direction key on the control device 100, so that after the focus cursor moves to any interface option position, the user can control the display device 200 to play the signal source content corresponding to the selected interface by pressing the 'ok' key. For example, when the user wants to watch a tv broadcast, the user may control the focus cursor to move to a tv broadcast option and press a "confirm" key, thereby controlling the display device 200 to obtain a tv broadcast signal from the digital tv signal line through the coaxial cable interface and present a corresponding picture in the tv broadcast signal through the display 260.

It can be seen that when the number of interfaces on the display device 200 is greater, the number of interface options included in the signal source interface is also greater, and in order to facilitate the user to switch signal sources, in some embodiments, the display device 200 may mark each interface option in the signal source interface so that the user can distinguish different signal sources. For example, as shown in fig. 7, after a coaxial cable interface connects a digital television signal line, the display device 200 may change the name of the interface to "live television" to characterize the signal source to which it is connected. Similarly, when the HDMI1 interface is connected to the game device, the display device 200 can support manual setting by the user, changing the name of the HDMI1 interface to "game machine".

By modifying the names of the interface options, the signal source interface displayed by the display device 200 may be made convenient for the user to distinguish the interface options. But the user may change the connection destination of the external device interface 240 when using the display apparatus 200, for example, change the HDMI1 interface from connecting a game machine to connecting a personal computer (Personal Computer, PC). At this time, since the destination of the interface connection has been changed, the display device 200 needs to synchronously modify the corresponding option names in the signal source interface, i.e., the user needs to modify the HDMI1 interface option name from "game machine" to "PC".

The modification process of the interface option name can be completed manually by a user according to an actual interface connection target, or can be completed automatically by the display device 200 by identifying the signal type and the picture characteristics corresponding to the interface. For example, the display apparatus 200 may incorporate an image recognition program, after the external device interface 240 receives the audio/video data, the display apparatus 200 may sample the image from the audio/video data, and invoke the image recognition program to perform image recognition on the sampled image, and the image recognition program may recognize features included in the image through optical feature word recognition (Optical Character Recognition, OCR) or a machine learning model, thereby determining a signal source type to which the image belongs, and further modifying the name of the interface option according to the signal source type.

However, since the number of signal source types that the display device 200 can access is numerous, and the audio/video content provided by some signal sources is not specific, for example, when the signal source that the display device 200 accesses is a tv live broadcast signal, the tv live broadcast signal may play different tv contents according to different channels and different time periods, and the played tv contents may include multiple picture forms such as movies, tv dramas, advertisements, news, sports games, game live broadcast, etc., which often have the same picture features, it is difficult to determine the exact signal source type by using the image recognition method of the display device 200, which leads to errors in the added interface option names.

To facilitate enabling the user to accurately know the signal source content corresponding to each interface option, in some embodiments, the display apparatus 200 may also add a content presentation window associated with each external device interface 240 in the signal source interface. That is, as shown in fig. 8, the interface options may be composed of a content presentation window and an interface name. The content presentation window may maintain a specific mutual positional relationship with the interface name according to UI layout characteristics of the display device 200. For example, the content presentation window may be located above the interface name.

The content display window can display the signal source content corresponding to the current interface in the forms of pictures, dynamic pictures, short videos or real-time video playing and the like. The specifically displayed content can be obtained by screenshot or extraction of the signal source corresponding to the current interface. For example, when the display device 200 is connected to the tv live signal line through the coaxial cable interface, the display device 200 may extract video data transmitted by the tv live signal line to obtain at least one frame of preview image therefrom, and then add the preview image to the content display window to display the tv live signal source corresponding to the current interface option through the preview image.

The content displayed in the content presentation window may also be obtained in other ways and updated as the user's use progresses. For example, for a live tv signal source, the display device 200 may send a request to the server 400 according to the current time, and after receiving the request, the server 400 may determine the current playing progress of the live tv signal according to the current time in the request, so as to match the corresponding preview image according to the playing progress.

Wherein the preview image may be generated by the server 400 from a play list of a default channel in the tv live signal. That is, the server 400 may acquire a representative image corresponding to each period as a preview image according to the play list of the default channel. For example, as shown in fig. 8, when the default channel "×tv-1" of the TV live signal plays a news program in the period of 7:00-9:00 am and plays a TV show "a" in the period of 9:00-11:00 am, the display device 200 may acquire a news program cover as a preview image of the present period, so that when the user controls the display device 200 to display the signal source interface in the period of 7:00-9:00, the news cover may be displayed in the TV live interface of the signal source interface. Similarly, when the user controls the display device 200 to display the signal source interface in the period of 9:00-11:00, the display device 200 may acquire the cover of the drama "a" as the preview image, so as to display the cover of the drama "a" on the live television interface of the signal source interface.

The content presentation window may also take different forms depending on the hardware configuration and access conditions of the display device 200. For example, for a display device 200 with a good hardware configuration and network condition, the content presentation window may display the source content in the form of a short video or a real-time video play. For the display device 200 with a general hardware configuration and network conditions, the content display window may display the signal source content in the form of a picture or a diagram.

In some embodiments, the display device 200 may also dynamically adjust the preview image presentation form of the content presentation window in the signal source interface according to the current computing resource consumption situation. That is, the memory monitoring module may be built in the display device 200 to monitor the memory usage of the display device 200 in real time, and when the memory usage of the display device 200 exceeds the memory threshold, the preview image may be displayed in the memory display window in the form of a picture or a dynamic picture, so as to reduce the occupation of memory resources; when the memory usage of the display device 200 does not exceed the memory threshold, the preview image may be displayed on the content display window in a form of short video or real-time video playing, so as to obtain a better content display effect.

Since the display device 200 may be provided with multiple interfaces, each interface may access a different signal source according to a specific connection manner thereof, a signal source interface presented by the display device 200 generally includes multiple interface options, and content presentation windows in the multiple interface options may each present preview image content corresponding to a current signal source. In order to control the specific preview image content in the content presentation window, in some embodiments of the present application, the display apparatus 200 may incorporate a signal source interface display method, and when the user controls the display apparatus 200 to display the signal source interface, the display apparatus 200 may control the specific content in the content presentation window by running the signal source interface display method.

Accordingly, in order for the display apparatus 200 to be able to operate the signal source interface display method, the display apparatus 200 should include at least a display 260, an external device interface 240, and a controller 250. Wherein the display 260 is used to display a variety of user interfaces including a signal source interface. The external device interface 240 may have specific interface specifications for connecting different devices or lines to connect multiple signal sources. As shown in fig. 9, the controller 250 may be configured to execute the above signal source interface display method, which specifically includes the following:

And receiving a control instruction which is input by a user and used for displaying the signal source interface. The user may control the display device 200 to display the signal source interface in a variety of ways. That is, in some embodiments, a user may control the display signal source interface through the control apparatus 100 that is associated with the display device 200. For example, a "signal source" button may be provided on the control apparatus 100, and when the user presses the "signal source" button, the display device 200 may be triggered to jump from the current interface to the display signal source interface.

In some embodiments, the user may also control the display device 200 to jump to the signal source interface based on UI interaction interface operations provided by the display device 200. For example, the user may control the movement of the focus cursor in the user interface by controlling the directional key on the apparatus 100, and when the focus cursor moves to the top option position of the current screen and then presses the "up" directional key, the display device 200 may be triggered to display a status bar, and in the status bar, a "signal source" option may be provided, and when the user controls the focus cursor to select the "signal source" option and then presses the "confirm" key, the display device 200 may jump to display the signal source interface. For another example, in the control homepage and the setting interface of the display apparatus 200, a "signal source" option may be provided, and when the user selects the option, the display apparatus 200 may be controlled to jump to the signal source interface.

It should be noted that, the display device 200 may also complete input of a control instruction for displaying the signal source interface according to other supported interaction modes. For example, for the display device 200 supporting the touch interactive operation, the user may select a status bar, control a homepage, and set a "signal source" option in the interface through touch operation, so as to obtain the same interaction manner as the key operation function of the control apparatus 100, that is, control the display device 200 to jump to the signal source interface. For the display device 200 supporting intelligent voice interaction, the user may also control the display device 200 to display a signal source interface by inputting voice "switching signal sources" after exhaling the intelligent voice assistant.

After the user inputs a control instruction for displaying the signal source interface, the display apparatus 200 may control the display of the signal source interface in the display 260 in response to the control instruction input by the user. In order to enable the user to accurately identify the signal source status of the corresponding connection of the interface options in the signal source interface, a plurality of interface options should be included in the signal source interface displayed by the display apparatus 200, and each interface option may include a content presentation window associated with the external device interface 240.

Therefore, before displaying the signal source interface, the display device 200 may display the content specifically displayed in the content display window according to the program corresponding to the signal source interface display method. I.e. the display apparatus 200 may acquire a preview image of the external device interface. The preview image is a display screen stored in advance according to a signal source connected to the external device interface 240. Specifically, the display screen may be a display screen that is stored in advance when the signal source of the external device interface 240 was previously cut out, a display screen that is stored in advance when the signal source of the external device interface 240 is subjected to screen extraction at a specific time point, or an image obtained by capturing a screen of the display screen when the external device interface 240 is played last time.

Depending on the form of the preview image screen specifically presented by the display apparatus 200, the form of the preview image acquired by the display apparatus 200 in response to the control instruction is also different. For example, when the preview image form displayed by the content presentation window is set to be a picture, the display apparatus 200 may acquire the preview image in the form of a picture; when the preview image displayed on the content presentation window is set to be in the form of a short video, the display device 200 may acquire a short video file corresponding to the current signal source.

After acquiring the preview image, the display apparatus 200 adds the preview image to the content presentation window and composes an interface option with the content such as the interface name. When the signal source interface includes a plurality of interface options, the display apparatus 200 may acquire preview images corresponding to each interface option (i.e., the external device interface 240) one by one, and add the acquired preview images to the content presentation window, thereby forming a final signal source interface. Finally, the controller 250 of the display device 200 may control the display 260 to display the signal source interface.

For example, as shown in fig. 10, when a coaxial cable interface, an HDMI1 interface, an HDMI2 interface are included on the display device 200 and a tv live signal line, a game device, a PC are connected, respectively, the display device 200 may display a tv live option, an HDMI1 option, and an HDMI2 option in the signal source interface. After a control instruction for displaying the signal source interface is input by a user, responding to the control instruction, and respectively acquiring preview images corresponding to the coaxial cable interface, the HDMI1 interface and the HDMI2 interface, namely, a live television picture screenshot, a game cover and a personal computer desktop pattern. And then adding the screenshot of the television live broadcast picture into a content display window of the television live broadcast option, adding a game cover into a content display window of the HDMI1 option, adding a desktop pattern of a personal computer into the HDMI2 option, and forming a final signal source interface to be displayed on the display 260.

In some embodiments, to present the content presentation window in the signal source interface, the display device 200 may obtain the final display effect of the signal source interface by way of overlapping multiple layers. For example, the Display apparatus 200 may set three layers, namely, a Video (Video) layer, an On-Screen Display (OSD) layer, and a group of pictures (Group Of Pictures, GOP) layer, in the process of rendering the signal source interface. After acquiring the control instruction for displaying the signal source interface, the display device 200 may extract a display template of the signal source interface from the UI template library according to the UI layout policy of the operating system, and form an initial signal source interface through the Video layer. Wherein the initial source interface on the Video layer does not contain a content presentation window.

After the initial signal source interface of the Video layer is rendered, the display device 200 may add a content display window in the OSD layer according to the position of each interface option in the Video layer. The position of each content presentation window is associated with the position of the interface option in the Video layer so that it can visually obtain the layer stacking effect.

After the OSD layer is rendered, the display apparatus 200 may further display a plurality of areas for displaying preview images at the GOP layer plan according to the positions of the respective content presentation windows in the OSD layer, so that after the display apparatus 200 acquires the preview images of the signal sources corresponding to each external device interface 240, the preview images corresponding to each content presentation window are displayed in the demarcated areas. It can be seen that, by superposition of the Video layer, the OSD layer and the GOP layer, a final signal source interface can be obtained, and by superposition of multiple layers, the signal source interface can include a content display window and a preview image displayed in the content display window.

According to the technical scheme, after the control instruction is input by the user, the method for displaying the signal source interface can automatically acquire the preview image pre-stored according to the connection signal source of each external device interface 240, and adds the acquired preview image to the content display window corresponding to each interface option, so that the current signal source of each interface is displayed, the user can conveniently distinguish each signal source through the preview image, know the corresponding content of each signal source, and control the display device 200 to switch to the designated signal source according to the self requirement.

Since a plurality of external device interfaces 240 may be included in the display apparatus 200, and the plurality of external device interfaces 240 may have different connection states, for example, the HDMI1 interface is connected to a game apparatus while the HDMI2 interface is not connected to any apparatus or signal line. Accordingly, the display apparatus 200 may also adjust the display form of each interface option according to the connection state in displaying the signal source interface. That is, as shown in fig. 11, in some embodiments, the display apparatus 200 may also detect the connection state of each external device interface 240 before acquiring the preview image of the interface option.

Wherein the connection state includes an accessed state and a non-accessed state. The display apparatus 200 may determine whether the current external device interface 240 is connected to a line or an apparatus by detecting parameters such as a signal input condition of the external device interface 240, a change in hot plug voltage, etc. When detecting that the current external device interface 240 has signal input or the hot plug voltage is at a high potential, determining that the connection state of the current external device interface 240 is an access state; otherwise, when no signal input of the current external device interface 240 is detected and the hot plug voltage is at a low potential, it is determined that the connection state of the current external device interface 240 is an unaccessed state.

The display apparatus 200 may display interface options in an adaptive manner according to the connection state of each external device interface 240. That is, if the external device interface 240 is in the connected state, the display apparatus 200 may perform the step of acquiring the preview image of the external device interface 240 and add the preview image to the content presentation window in the manner of the above-described embodiment, forming a screen interface option with the preview image and a source interface displayed in the display 260.

If the external device interface 240 is in the unaccessed state, the display apparatus 200 may skip the step of acquiring the preview image, but add a default icon in the content presentation window. The default icons may be formed in patterns, text, and combinations thereof, depending on the particular form of the interface. Since the external device interface 240 in the unaccessed state generally cannot provide a specific display screen or audio content to the display apparatus 200, the display apparatus 200 may also control the display 240 to display a content presentation window through a gray pattern in order to guide the user not to select the interface option.

For example, as shown in fig. 12, by detecting the connection states of the external device interfaces 240, it is determined that the connection states of the respective external device interfaces 240 of the present display apparatus 200 are respectively: the coaxial cable interface is in an access state, the HDMI1 interface is in an access state, and the HDMI2 interface is in a non-access state. The display device 200 may perform the steps of acquiring the preview image for the coaxial cable interface and the HDMI1 interface to display the live tv screenshot and the game cover through the content presentation window, presenting the signal source contents of the coaxial cable interface and the HDMI1 interface. For the HDMI2 interface, the display device 200 may add a default icon representing the shape of the HDMI interface in the content presentation window, and display the content presentation window in gray scale to represent a state that the HDMI2 interface is not connected to an available signal source.

It can be seen that, in the above embodiment, the display device 200 may display, in the signal source interface, the connection state of the option corresponding to the external device interface 240 through different interface option display forms, that is, the gray signal source represents that the channel is empty, the device or signal line is not connected, the highlighted signal source represents that the channel has been connected to the device or signal line, and the corresponding signal source content is displayed through the preview image.

Since a plurality of external device interfaces 240 may be included in the display apparatus 200 and the plurality of external device interfaces 240 may be connected to different apparatuses or signal lines, a plurality of interface options need to be displayed in the signal source interface. The plurality of interface options may be arranged according to a frequency of use or the like, and their display order in the signal source interface may be set. For example, the default display order of interface options in the signal source interface is: a live television interface, an HDMI (1, 2,3 …) interface, a component interface, an audio-video interface, a video graphics array (Video Graphics Array, VGA) interface, a digital video (Digital Visual Interface, DVI) interface, a USB-typeC interface, a USB interface, and a digital living network alliance (Digital Living Network Alliance, DLNA) interface. The interface options may be arranged in a line or a rectangular array according to the above sequence, so that the user can conveniently select the frequently played signal source by pressing the direction key of the control device 100 a small number of times.

When a plurality of interface options are displayed in the signal source interface, the display apparatus 200 may adjust the arrangement sequence of the interface options according to the access state of each interface option corresponding to the external device interface 240, so as to facilitate the user to quickly select an effective signal source. In some embodiments, when the content presentation windows are arranged in a line in the signal source interface, the display apparatus 200 may traverse the connection state of the external device interface 240 and calculate the arrangement priority of the content presentation windows according to the connection state. And then adjusting the arrangement sequence of the content display window in the signal source interface according to the arrangement priority.

In the calculated arrangement priority, the content display window in the access state is higher than the content display window in the non-access state. In order to calculate the ranking priority, the display apparatus 200 may calculate the priority by a value-added operation on the basis of the default ranking order. For example, the display device 200 may assign a value to each interface option according to a default arrangement sequence, i.e., a value of 1 to a live tv interface arranged in the first position by default, 0.99 to an HDMI1 interface arranged in the second position by default, and 0.98 to … … to an HDMI2 interface arranged in the third position by default

According to the assignment result, the display device 200 sets the adjustment value according to the connection state, that is, the adjustment value of the access state is 1, and the adjustment value of the non-access state is 0. The adjustment value and the default assignment are summed, that is, by traversing the connection states of the external device interfaces 240, it can be determined that the external device interfaces 240 currently in the access state are: and calculating the corresponding priority judgment value of the live television interface in the access state to be 1+1=2 according to the connection state, and calculating the corresponding priority judgment value of the HDMI1 interface in the non-access state to be 0.99+0=0.99. Similarly, according to the above calculation method, the HDMI2 interface corresponding priority determination value is 0.98+1=1.98, and the USB interface corresponding priority determination value is 0.3+1=1.3.

As shown in fig. 13, after calculating the priority judgment value corresponding to each interface, the display device 200 may adjust the display sequence of the interface options again according to the sequence of the priority judgment values from large to small, so that the live tv interface, the HDMI2 interface and the USB interface in the access state are arranged in a front position, so that the user may select the available signal sources through fewer interaction operations.

It should be noted that, in the process of adjusting the display order of the interface options according to the connection state, the display apparatus 200 still maintains the default display order for the external device interface 240 in the co-located access state or the co-located non-access state. For example, when the live tv interface, the HDMI2 interface, and the USB interface are all in the connected state, the display device 200 may still make the live tv interface in the first order, the HDMI2 interface in the second order, and the USB interface in the third order according to the default display order after displaying the three interface options in the front position, so that the user selects the interface that is used frequently and has a signal input at present as the signal source.

After setting the display order of the interface options, the display apparatus 200 may add a preview image to the content presentation window corresponding to the interface options in the manner described in the above embodiments, and in some embodiments, the preview image may be a display screen saved by the user when the external device interface 240 was cut out last time. For this reason, the display apparatus 200 needs to generate and save a preview image each time the current signal source is cut out. That is, as shown in fig. 14, the display device 200 may first acquire an exit instruction for exiting the play interface, which is input by the user.

The exit command for exiting the playing interface may be input by means of a key on the control device 100, a UI interface of a system operated by the display device 200, touch interaction operation, intelligent voice interaction, and the like, similar to the input manner of the control command for displaying the signal source interface in the above embodiment. For example, the user may control the cutting of the current signal source by pressing the "exit" key on the control apparatus 100 while the display device 200 displays the play interface.

In the interaction process, since the display device 200 can only play audio/video data corresponding to one signal source, when the user controls the display device 200 to switch to a new signal source, the original signal source is cut out. At this time, an exit instruction for exiting the playback interface is also entered on behalf of the user.

After acquiring the exit instruction, the display device 200 responds to the exit instruction, and generates a preview image according to the cut audio-video data content of the original signal source. The method for generating the preview image can comprise the steps of executing screenshot on a display screen in a playing interface to generate the preview image; and extracting a frame of picture corresponding to the cutting-out moment from the audio and video data corresponding to the display picture in the playing interface so as to generate a preview image. After generating the preview image, the display device 200 stores the preview image, so that the stored preview image can be added to the content presentation window when the signal source interface is displayed next time, and display of the signal source interface is completed.

Since the external device interface 240 on the display apparatus 200 can be connected to various apparatuses, part of the interfaces may have different forms according to the connection apparatuses. For example, with respect to the USB interface, general-purpose data such as files, data, programs, etc. are transferred in some usage environments, that is, not used as a signal source. In some usage environments, the display device 200 may also be connected to devices such as an intelligent terminal through a USB interface, so as to transmit audio and video data, i.e. to be used as a signal source. In contrast, HDMI interfaces, coaxial cable interfaces, and the like are generally used only for transmitting audio/video data, i.e., are always used as signal sources. For convenience of description, the present application refers to an interface that is always used as a signal source as a first type interface, and refers to an interface that is partly used as a signal source and partly used as no signal source as a second type interface.

In the process of displaying the signal source interface, for the second type of interface, the display device 200 can control whether the second type of interface is a content display window corresponding to the signal source interface according to the connection state of the second type of interface, so that the number of content display windows in the signal source interface is reduced, and the interface content is simplified. That is, as shown in fig. 15, in some embodiments, the display apparatus 200 may traverse the interface type of the external device interface 240 prior to the step of acquiring the preview image of the interface option. The interface type comprises a first type of interface for transmitting audio and video data and a second type of interface for transmitting general data.

According to the traversing result of the interface type, if the interface type of the external device interface 240 is the first type interface, the step of obtaining the preview image of the external device interface 240 is performed, that is, according to the signal source interface display mode in the above embodiment, the signal source interface display is performed by obtaining the preview image and adding the preview image to the content display window.

If the interface type of the external device interface 240 is the second type interface, detecting the connection state of the second type interface, and hiding the content display window corresponding to the external device interface 240 when the connection state is not accessed. For example, by detecting the interface type of the external device interface 240, it may be determined that the USB interface and the DLNA interface are the second type of interface, and then by detecting the connection state of the USB interface and the DLNA interface, the USB interface and the DLNA interface are displayed in the signal source interface after the USB interface and the DLNA interface are accessed, and are not displayed when the USB interface and the DLNA interface are not accessed.

In some embodiments, the display device 200 may display the device name corresponding to the interface while displaying the content presentation window, that is, in the step of controlling the display 260 to display the signal source interface, obtain the device name of the device connected to the external apparatus interface 240, and display the device name in the association area of the content presentation window in the signal source interface. That is, for the external device interface 240 with signal access, the display apparatus 200 may replace the interface name with the name of the signal source apparatus to be presented.

For example, when the HDMI1 interface is connected to a game device, the display device 200 may determine that the current interface is connected to the game device by reading the device information frame data obtained by the HDMI1 interface and reading the device type therefrom. And then the original name 'HDMI 1' of the interface option is replaced by the corresponding device name of the game device, such as 'game machine','s- × (model) game machine', so as to form a new interface option, thereby facilitating understanding and recognition of a user.

In some embodiments, the user may also control the content presentation window in the signal source interface through a specific interaction operation, so as to control playing corresponding signal source content in real time. That is, as shown in fig. 16, the display apparatus 200 may detect a stay time of the focus cursor on the content presentation window in the signal source interface after the signal source interface is displayed by the control display 260. The detected stay time length can be used for comparing with a preset time length threshold, when the stay time length is greater than the time length threshold, namely, it is determined that the user wants to play the corresponding signal source content in real time through the content display window, so that the display device 200 can acquire the media asset data received by the content display window corresponding to the external device interface 240, and play the media asset data in the content display window.

For example, as shown in fig. 17, according to the operation habit of the user, the time duration threshold may be preset to be 3s, that is, when the focus cursor stays above the content presentation window 3s, the real-time preview function of the display apparatus 200 may be triggered. Based on this, as shown in fig. 18, when the display device 200 detects that the focus cursor is located above the tv live interface 3s, a digital tv signal corresponding to the tv live interface may be acquired, and the digital tv signal is played in real time through the content display window, so as to preview the current signal source content in real time.

Therefore, by controlling the stay time of the focus cursor on each interface option, the user can preview the current content of each interface on the premise of not switching the signal source of the display device 200, thereby facilitating the user to learn the current picture content of each interface, and improving the accuracy of the switching process of the signal source of the user.

In the process that the display apparatus 200 previews the signal source contents of each interface through the content presentation window, if the focus cursor is always on one interface option, the display apparatus 200 may always play the signal source contents corresponding to the external device interface 240 in real time. When the focus cursor is removed from the interface option, the display device 200 may stop playing the content of the content display window, and continue to determine the stay time for other interface options.

In some embodiments, for a particular interface option, when the user controls to remove the focus cursor, its content presentation window may retain the display of the moment of cursor removal as a preview image and be displayed in the content presentation window. That is, the display device 200 may acquire a movement instruction for moving the focus cursor input by the user, extract a last frame image of the input time of the movement instruction from the media asset data in response to the movement instruction, and finally replace the content displayed in the content presentation window with the last frame image.

For example, as shown in fig. 19, when the user controls the focus cursor to stay on the tv live interface for more than 3s, the display device 200 may play the tv live screen in real time in the content display window corresponding to the tv live interface. And, when the user moves the focus cursor to the HDMI1 interface option through the "right" direction key on the control device 100, the display device 200 may stop the real-time playing process of the content display window in the tv live broadcast interface option, and determine the stay time of the cursor on the HDMI1 interface, so as to play the signal source picture received by the HDMI1 interface in real time through the content display window corresponding to the HDMI1 interface when the stay time exceeds 3 s.

While the focus cursor moves out of the tv live interface option, the display device 200 may retain the tv live screen content, i.e., the last frame image, at the time of focus cursor movement out as a preview image. And replacing the content in the content display window corresponding to the television live broadcast interface through the generated preview image.

Based on the above signal source interface display method, some embodiments of the present application further provide a display device 200, where the display device 200 includes: a display 260, an external device interface 240, and a controller 250. Wherein the display 260 is configured to display a user interface including a signal source interface for displaying a plurality of signal sources; the external device interface 240 is configured to connect a plurality of signal sources; as shown in fig. 20, the controller 250 is configured to perform the following program steps:

As can be seen from the above technical solution, the display apparatus 200 provided in the above embodiment may obtain, as the preview image, the display screen pre-stored according to the signal source corresponding to the external device interface 240 after the control instruction for displaying the signal source interface is input by the user. And adding the preview image to the content presentation window for display in the signal source interface. The display device 200 can display the signal source correspondingly connected to each external device interface 240 through the content display window, so that the content displayed on the signal source interface is more visual, the user can know the access condition corresponding to the signal source, and the user can select the signal source correctly.

After the signal source interface is displayed, the stay time of the focus cursor on any content display window in the signal source interface can be detected, and when the stay time exceeds a time threshold, the media data corresponding to the content display window is obtained, and the obtained media data is played in the content display window. The display device 200 can control the content of the current signal source to preview in the content display window by controlling the stay time of the focus cursor on the content display window, so that a user can know the content corresponding to other signal sources on the premise of not cutting out the current signal source, and the user can switch the signal sources correctly.

The above-provided detailed description is merely a few examples under the general inventive concept and does not limit the scope of the present application. Any other embodiments which are extended according to the solution of the application without inventive effort fall within the scope of protection of the application for a person skilled in the art.
