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

In the embodiment of the present application, the signal source generally refers to various resource servers, external devices, signal networks, and the like, which can provide specific display images for the display device 200. The display apparatus 200 may be connected to different apparatuses, 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 the user may connect the coaxial cable interface to a digital television signal line to receive a live television 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 interface 240 may also be provided in plurality, the display apparatus 200 may simultaneously access 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 connect external devices or signal lines in its prescribed interface form. In order to enrich the media playing 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.

It is apparent that the external device interface 240 under the same type can also connect different types of signal sources. For example, the display device 200 connects 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 a digital television set-top box via an HDMI2 interface to receive live television signals via 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-casting 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, at this time, a signal source of the display device 200 is the communication terminal 300. In addition, other devices or networks that establish a connection with the display device 200 in a specific communication manner, including but not limited to a wired network, a wireless network, bluetooth, infrared, NFC, etc., may also be used as the signal source of 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 realizes the playing of the picture content of other signal sources by switching the signal sources. For example, when a user wants to watch a tv live broadcast, the signal source of the display apparatus 200 may be set to be the coaxial cable interface, so as to play the tv live broadcast signal transmitted by the coaxial cable interface. When the user wants to play a game, the signal source of the display device 200 may be controlled to be the HDMI1 interface, so as to play the game picture signal transmitted by the game device.

The signal source interface can provide operations of signal source selection, switching and the like for a user. Thus, there may be multiple interface options in the signal source interface. For example, as shown in fig. 6, the signal source interface may include a live tv (coaxial cable interface) option, an HDMI1 option, an HDMI2 option, a USB option, a screen projection option, and the like. The user can control the focus cursor in the signal source interface to move among the interface options through the direction keys 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 "confirm" key. For example, when the user wants to watch the tv live broadcast, the user may control the focus cursor to move to the tv live broadcast option and press the "ok" key, so as to control the display device 200 to obtain the tv live broadcast signal from the digital tv signal line through the coaxial cable interface and present the corresponding picture in the tv live broadcast signal through the display 260.

As can be seen, when the number of interfaces on the display device 200 is larger, the number of interface options included in the signal source interface is also larger, so as to facilitate the user to switch the signal source, 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 the coaxial cable interface connects the digital television signal line, the display device 200 may change the name of the interface to "live television" to characterize the signal source it accesses. Similarly, when the HDMI1 interface is connected to a game device, the display device 200 can support manual setting by the user, changing the name of the HDMI1 interface to "game machine".

The signal source interface displayed by the display device 200 may be made to be convenient for the user to distinguish the interface options by modifying the names of the interface options. However, when the user uses the display apparatus 200, the user may change the connection destination of the external device interface 240, for example, changing the HDMI1 interface from connecting a game machine to connecting a Personal Computer (PC). At this time, since the target of the interface connection has been changed, the display apparatus 200 needs to synchronously modify the corresponding option name 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 manually modified by a user according to an actual interface connection target, or can be automatically modified by the display device 200 by identifying a signal type and a picture characteristic corresponding to the interface. For example, the display apparatus 200 may be internally provided with an image Recognition program, after the external device interface 240 receives the audio/video data, the display apparatus 200 may perform image sampling from the audio/video data, and call the image Recognition program to perform image Recognition on an image obtained by the image sampling, where the image Recognition program may recognize features included in the image through Optical Character Recognition (OCR) or a machine learning model, so as to determine a signal source type to which the image belongs, and further modify a name of an interface option according to the signal source type.

However, the types of signal sources that the display device 200 can access are numerous, and audio and video content provided by a part of the signal sources does not have specificity, for example, when the signal source that the display device 200 accesses is a live television signal, the live television signal can play different television content according to different channels and different time periods, the played television content can include various picture forms such as movies, dramas, advertisements, news, sports events, live games, and the like, and the picture forms often have the same picture characteristics, so that it is difficult to determine the accurate signal source type through the image identification method of the display device 200, which causes an error in the name of an added interface option.

To facilitate enabling a user to accurately know the signal source content corresponding to each interface option, in some embodiments, the display apparatus 200 may further 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 option may be composed of a content presentation window and an interface name. The contents presentation window may maintain a specific mutual positional relationship with the interface name according to the 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 performing screenshot or extraction on the signal source corresponding to the current interface. For example, when the display device 200 is connected to a live tv signal line through a coaxial cable interface, the display device 200 may extract video data transmitted by the live tv signal line to obtain at least one frame of preview image, and add the preview image in a content display window to display a live tv signal source corresponding to a current interface option through the preview image.

The content displayed in the content display window can also be obtained in other ways and updated along with the use process of the user. 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 broadcast schedule of the live tv signal according to the current time in the request, so as to match a corresponding preview image according to the broadcast schedule.

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

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

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

Because the display device 200 may be provided with multiple interfaces, each interface may access different signal sources according to a specific connection manner, the signal source interface presented by the display device 200 generally includes multiple interface options, and a content display window in the multiple interface options may present preview image content corresponding to the current signal source. In order to control the specific preview image content in the content display window, in some embodiments of the present application, the display device 200 may be built in with a signal source interface display method, and when the user controls the display device 200 to display a signal source interface, the display device 200 may control the specific content in the content display window by operating 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 the display 260, the external device interface 240, and the controller 250. The display 260 is used to display various user interfaces including a signal source interface. The external device interface 240 may have a specific interface specification for connecting different apparatuses or lines to connect a plurality of signal sources. As shown in fig. 9, the controller 250 may be configured to execute the signal source interface display method, which specifically includes the following steps:

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, the user may control the display signal source interface through the control device 100 associated with the display apparatus 200. For example, a "signal source" key may be provided on the control apparatus 100, and when the user presses the "signal source" key, 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 apparatus 200 to jump to the signal source interface based on the UI interaction interface operation provided by the display apparatus 200. For example, the user may control the movement of the focus cursor in the user interface through the direction key on the control device 100, when the focus cursor moves to the top option position of the current screen and then presses the "up" direction key, the display device 200 may be triggered to display the status bar, the "signal source" option may be set in the status bar, and after 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 the display signal source interface. For another example, a "signal source" option may be provided in the control home page and setting interface of the display device 200, and when the user selects the option, the display device 200 may be controlled to jump to the signal source interface.

It should be noted that the display device 200 may also complete the input of the control command of the display signal source interface according to other supported interaction modes. For example, for the display device 200 supporting touch interactive operation, the user may select the status bar, the control home page, and the "signal source" option in the setting interface through touch operation, so as to obtain the same interactive mode 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 the intelligent voice interaction, after calling the intelligent voice assistant, the user may also control the display device 200 to display the signal source interface by inputting voice "switch the signal source".

After the user inputs a control instruction for displaying the signal source interface, the display apparatus 200 may control the signal source interface to be displayed in the display 260 in response to the control instruction input by the user. In order to enable the user to accurately identify the status of the signal source connected to each interface option in the signal source interface, a plurality of interface options are included in the signal source interface displayed by the display apparatus 200, and each interface option may include a content display 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. That is, the display apparatus 200 may acquire a preview image of the interface of the external device. The preview image is a display image pre-stored according to a signal source connected to the external device interface 240. Specifically, the display screen may be a display screen that is previously saved when the signal source of the external device interface 240 was cut out last time, a display screen that is previously saved by performing screen extraction at a specific time point with respect to the signal source of the external device interface 240, or an image obtained by capturing a screen of the display screen when the external device interface 240 was played last time.

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

After the preview image is acquired, the display device 200 adds the preview image to the content display window, and forms 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 a preview image corresponding to each interface option (i.e., the external device interface 240) one by one, and add the acquired preview image to the content display window, thereby forming a final signal source interface. Finally, the controller 250 of the display apparatus 200 may control the display 260 to display the signal source interface.

For example, as shown in fig. 10, when the display apparatus 200 includes a coaxial cable interface, an HDMI1 interface, and an HDMI2 interface thereon, and connects a live tv signal line, a game apparatus, and a PC, respectively, the display apparatus 200 can display a live tv option, an HDMI1 option, and an HDMI2 option in the signal source interface. And after a user inputs a control instruction for displaying a signal source interface, previews 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, are respectively obtained in response to the control instruction. And adding the live television picture screenshots into a content display window of a live television option, adding a game cover into the content display window of the HDMI1 option, adding a personal computer desktop pattern into the HDMI2 option, and forming a final signal source interface to be displayed on the display 260.

In some embodiments, in order to present the content presentation window in the signal source interface, the display device 200 may obtain a final display effect of the signal source interface by overlapping a plurality of layers. For example, the Display apparatus 200 may set three layers, i.e., a Video (Video) layer, an On-Screen Display (OSD) layer, and a Group Of Pictures (GOP) layer, in the process Of rendering a signal source interface. After obtaining the control instruction for displaying the signal source interface, the display device 200 may extract the display template of the signal source interface in 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 signal source interface on the Video layer does not include 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 on 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 the overlay effect can be obtained visually.

After rendering the OSD layer, the display apparatus 200 may further display a plurality of regions for displaying the preview images at the GOP layer plan according to the positions of the content presentation windows in the OSD layer, so that after the display apparatus 200 acquires the preview image of the signal source corresponding to each external device interface 240, the preview image corresponding to each content presentation window is displayed in the defined region. Therefore, a final signal source interface can be obtained through superposition of the Video layer, the OSD layer and the GOP layer, and the signal source interface can comprise a content display window and a preview image displayed in the content display window through superposition of a plurality of layers.

According to the above technical solution, after the user inputs a control instruction, the signal source interface display method may automatically obtain the preview image pre-stored according to the connection of each external device interface 240 with the signal source, and add the obtained preview image to the content display window corresponding to each interface option, so as to display the current signal source of each interface, thereby facilitating the user to distinguish each signal source through the preview image, know the content corresponding to each signal source, and control the display device 200 to switch to the specified signal source according to the need of the user.

Since the 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 HDMI2 interface does not connect any apparatus or signal line while the HDMI1 interface connects the game apparatus. Therefore, the display apparatus 200 may also adjust a display form of each interface option according to a 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 a preview image of the interface option.

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

The display apparatus 200 may display the interface options in an appropriate 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 in the manner of the above-described embodiment, and add the preview image to the content presentation window, forming a screen interface with the preview image and a signal source interface to be displayed in the display 260.

If the external device interface 240 is in a non-accessed state, the display apparatus 200 may skip the step of acquiring the preview image and add a default icon in the content presentation window. The default icon may be formed in a pattern, text, or a combination thereof, according to the specific 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 by 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 state of the external device interface 240, it is determined that the connection state of each external device interface 240 of the current display apparatus 200 is: the coaxial cable interface is in an access state, the HDMI1 interface is in an access state, and the HDMI2 interface is in an unaccessed state. The display apparatus 200 may perform the steps of acquiring a preview image for the coaxial cable interface and the HDMI1 interface to display a live tv screenshot and a game cover through the content display window to display the signal source content 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 grayscale to represent the state that the HDMI2 interface is not connected to an available signal source.

It can be seen that, in the above embodiment, the display apparatus 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, a grayed signal source represents that the channel is empty, no device or signal line is accessed, a highlighted signal source represents that the channel has accessed the device or signal line, and display the corresponding signal source content through a preview image.

Since a plurality of external device interfaces 240 may be included in the display apparatus 200, and a 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 can set the display sequence of the interface in the signal source according to the arrangement rule such as the use frequency. For example, the default display order of the 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 (VGA) Interface, a Digital Video Interface (DVI) Interface, a USB-type c Interface, a USB Interface, and a Digital Living Network Alliance (DLNA) Interface. The plurality of interface options can be arranged in a line-shaped arrangement or a rectangular array according to the sequence, so that a user can conveniently select a frequently played signal source by pressing the direction key of the control device 100 for a small number of times.

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

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

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

As shown in fig. 13, after calculating the priority determination value corresponding to each interface, the display device 200 may adjust the display order of the interface options again according to the order from the highest priority determination value to the lowest priority determination value, so that the live tv interface, the HDMI2 interface, and the USB interface in the connected state are arranged at the front position, so that the user may select an available signal source through a few times of interaction.

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 apparatus 200 may, after displaying the three interface options in the front positions, still follow the default display order, so that the live tv interface is in the first position, the HDMI2 interface is in the second position, and the USB interface is in the third position, so that the user selects the interface with high use frequency and currently having a signal input 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 embodiment, and in some embodiments, the preview image may be a display screen saved when the user previously cuts out the external device interface 240. 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 obtain an exit instruction for exiting the play interface, which is input by the user.

The quitting instruction for quitting the playing interface may also be input in a manner similar to the input manner of the control instruction for displaying the signal source interface in the foregoing embodiment, by using 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. For example, the user may control to switch out the current signal source by pressing an "exit" key on the control apparatus 100 when the display device 200 displays the play interface.

In the interaction process, since the display device 200 can only play audio and 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 switched out. At this time, an exit instruction for exiting the play interface is also input on behalf of the user.

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

Since the external device interface 240 on the display apparatus 200 can connect various apparatuses, some of the interfaces may have different forms according to the connected apparatuses. For example, in some usage environments, the USB interface is used to transfer general data such as files, data, and programs, i.e., not used as a signal source. In some usage environments, the display device 200 may also be connected to a device such as an intelligent terminal through a USB interface to transmit audio and video data, that is, to serve as a signal source. As for the HDMI interface, the coaxial cable interface, etc., they are usually only used for transmitting audio/video data, i.e., they are always used as signal sources. For convenience of description, in the present application, an interface that has been used as a signal source is referred to as a first type interface, an interface that has a partial environment as a signal source and has a partial environment as a signal source is referred to as a second type interface.

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

According to the traversal 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 executed, that is, according to the signal source interface display mode in the above embodiment, the signal source interface is displayed 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 status of the USB interface and the DLNA interface, the USB interface and the DLNA interface are displayed in the signal source interface after having equipment access, and are not displayed if not.

In some embodiments, while the display apparatus 200 displays the content presentation window, the display apparatus may also display a name of an apparatus connected to the interface, that is, in the step of controlling the display 260 to display the signal source interface, the apparatus name of the apparatus connected to the external device interface 240 is obtained, and the apparatus name is displayed in the associated 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 shown.

For example, when the HDMI1 interface connects a game device, the display device 200 may determine that the game device is currently interfaced by reading device information frame data obtained by the HDMI1 interface and reading the device type therefrom. And then replacing the original name of the interface option "HDMI 1" with the corresponding device name of the game device, such as "game machine", "s-xxx (model) game machine", to form a new interface option for the user to understand and recognize.

In some embodiments, the user may also control the content display window in the signal source interface through a specific interactive operation to control the real-time playing of the corresponding signal source content. That is, as shown in fig. 16, the display device 200 may detect a dwell time of the focus cursor on the content presentation window in the signal source interface after controlling the display 260 to display the signal source interface. The detected staying time duration can be used for comparing with a preset time duration threshold, and when the staying time duration is greater than the time duration threshold, 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 external device interface 240 corresponding to the content display window 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 duration threshold may be set to be 3s in advance, that is, when the focus cursor stays above the content presentation window 3s, the real-time preview function of the display device 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 live tv interface 3s, the digital television signal corresponding to the live tv interface may be acquired, and the digital television signal may be played in real time through the content display window, so as to preview the content of the current signal source in real time.

Therefore, by controlling the dwell 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 signal source switching process of the user.

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

In some embodiments, for a particular interface option, when the user controls to move the focus cursor away, the content presentation window may retain the display at the time of cursor removal as a preview image and display 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, and in response to the movement instruction, extract the last frame image at the input time of the movement instruction in the asset data, 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 live tv interface for more than 3s, the display device 200 may play a live tv picture in real time in a content display window corresponding to the live tv interface. And, when the user moves the focus cursor to the HDMI1 interface option through the "right" arrow 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 interface option, and determine the dwell 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 dwell 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 picture content at the time of the focus cursor moving out, that is, the last frame image, as the preview image. And replacing the content in the content display window corresponding to the live television interface by the generated preview image.

Based on the signal source interface display method, in some embodiments of the present application, a display device 200 is further provided, 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 execute the following program steps:

As can be seen from the above technical solutions, the display apparatus 200 provided in the above embodiment may obtain, as a preview image, a display screen pre-saved in correspondence to a signal source according to the external device interface 240 after a user inputs a control instruction for displaying a signal source interface. And adding the preview image to the content presentation window for display in the signal source interface. The display device 200 may 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 intuitive, a user can know the access status corresponding to the signal source conveniently, and the user can select the signal source correctly.

And after the signal source interface is displayed, the dwell time of a focus cursor on any content display window in the signal source interface can be detected, the media asset data corresponding to the content display window is acquired when the dwell time exceeds a time threshold, and the acquired media asset data is played in the content display window. The display device 200 can control the content of the current signal source to be previewed 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 source correctly.

The embodiments provided in the present application are only a few examples of the general concept of the present application, and do not limit the scope of the present application. Any other embodiments extended according to the scheme of the present application without inventive efforts will be within the scope of protection of the present application for a person skilled in the art.
