基于上述显示设备200,用户可以通过特定的交互动作控制显示设备200呈现不同的用户界面。其中,用户界面可以根据其具体提供的功能不同,细分为多种类型。例如,显示设备200所提供的用户界面可以包括用于控制切换信号源的信号源界面。Based on thedisplay device 200 described above, the user can control thedisplay device 200 to present different user interfaces through specific interactive actions. Among them, the user interface can be subdivided into various types according to the different functions it specifically provides. For example, the user interface provided by thedisplay device 200 may include a signal source interface for controlling switching of signal sources.

在本申请实施例中,所述信号源泛指能够为显示设备200提供具体显示画面的各种资源服务器、外接设备、信号网络等。显示设备200可以通过外部装置接口240连接不同的设备、线路以连接不同的信号源。如图5所示,例如,外部装置接口240可以是显示设备200上设置的同轴电缆接口,用户可以将同轴电缆接口连接数字电视信号线,以从数字电视信号线接收电视直播信号,并在显示器260上进行播放。又例如,外部装置接口24可以是显示设备200上设置的HDMI接口,用户可以将HDMI接口连接游戏设备,以从游戏设备获得游戏画面信号,并在显示器260上进行播放。In this embodiment of the present application, the signal source generally refers to various resource servers, external devices, signal networks, etc. that can provide specific display images for thedisplay device 200 . Thedisplay device 200 can be connected to different devices and lines through theexternal device interface 240 to connect to different signal sources. As shown in FIG. 5, for example, theexternal device interface 240 can be a coaxial cable interface provided on thedisplay device 200, and the user can connect the coaxial cable interface to a digital TV signal line to receive live TV signals from the digital TV signal line, and Play ondisplay 260 . For another example, the external device interface 24 may be an HDMI interface provided on thedisplay device 200 , and the user may connect the HDMI interface to a game device to obtain a game screen signal from the game device and play it on thedisplay 260 .

由于显示设备200上可以设有多种类型的外部装置接口240,并且每种类型的外部装置接口240的数量也可以设有多个,因此显示设备200可以同时接入多个信号源。例如,显示设备200上可以设有同轴电缆接口、HDMI接口、USB接口以及AV接口等外部装置接口240。每个类型的外部装置接口240可以按照其规定的接口形式连接外接设备或信号线。而为了丰富显示设备200的媒资播放内容,显示设备200上可以设有两个HDMI接口,即HDMI1接口和HDMI2接口。Since multiple types of external device interfaces 240 can be provided on thedisplay device 200 , and the number of each type ofexternal device interface 240 can also be multiple, so thedisplay device 200 can simultaneously access multiple signal sources. For example, thedisplay device 200 may be provided with external device interfaces 240 such as a coaxial cable interface, an HDMI interface, a USB interface, and an AV interface. Each type ofexternal device interface 240 can be connected with external devices or signal lines according to its prescribed interface form. In order to enrich the media playing content of thedisplay device 200 , thedisplay device 200 may be provided with two HDMI interfaces, that is, an HDMI1 interface and an HDMI2 interface.

显然,同一种类型下的外部装置接口240也可以连接不同类型的信号源。例如,显示设备200通过HDMI1接口连接游戏设备,以接收游戏设备生成的游戏画面数据;显示设备200还通过HDMI2接口连接数字电视机顶盒,以通过机顶盒接收电视直播信号。Obviously, the same type ofexternal device interface 240 can also be connected to different types of signal sources. For example, thedisplay device 200 is connected to the game device through the HDMI1 interface to receive game screen data generated by the game device; thedisplay device 200 is also connected to the digital TV set-top box through the HDMI2 interface to receive live TV signals through the set-top box.

需要说明的是,显示设备200的信号源并不局限于上述通过外部装置接口240的连接形式,还可以支持其他类型的连接形式。即在一些实施例中,显示设备200还可以通过通信器220连接信号源。例如,通信器220中可以内置无线网络模块,显示设备200可以通过无线网络模块与通信终端建立投屏连接,从而同步播放通信终端上显示的内容,即此时显示设备200的信号源为通信终端。此外,对于其他以特定通信方式与显示设备200建立连接的设备或网络也可以作为显示设备200的信号源,所述特定通信方式包括但不限于有线网络、无线网络、蓝牙、红外、NFC等。It should be noted that the signal source of thedisplay device 200 is not limited to the above-mentioned connection form through theexternal device interface 240 , and may also support other types of connection forms. That is, in some embodiments, thedisplay device 200 can also be connected to a signal source through thecommunicator 220 . For example, a wireless network module can be built in thecommunicator 220, and thedisplay device 200 can establish a screen projection connection with the communication terminal through the wireless network module, so as to synchronously play the content displayed on the communication terminal, that is, the signal source of thedisplay device 200 is the communication terminal at this time. . In addition, other devices or networks that establish a connection with thedisplay device 200 through a specific communication method can also be used as a signal source of thedisplay device 200, and the specific communication method includes but is not limited to a wired network, a wireless network, Bluetooth, infrared, NFC, and the like.

为了使显示设备200能够正常呈现每个信号源中的画面内容,显示设备200在使用中通常仅播放一个信号源对应的音视频数据,并通过切换信号源的方式实现对其他信号源画面内容的播放。例如,当用户想要观看电视直播时,可以设置显示设备200的信号源为同轴电缆接口,从而播放同轴电缆接口传递的电视直播信号。而当用户想要进行游戏时,可以控制显示设备200的信号源为HDMI1接口,从而播放游戏设备传递的游戏画面信号。In order to enable thedisplay device 200 to normally present the picture content in each signal source, thedisplay device 200 usually only plays the audio and video data corresponding to one signal source during use, and realizes the picture content of other signal sources by switching the signal source. play. For example, when the user wants to watch live TV, the signal source of thedisplay device 200 can be set as a coaxial cable interface, so as to play the live TV signal transmitted by the coaxial cable interface. And when the user wants to play a game, he can control the signal source of thedisplay device 200 to be the HDMI1 interface, so as to play the game screen signal transmitted by the game device.

信号源界面可以为用户提供信号源选择、切换等操作。因此,在信号源界面中可以设有多个接口选项。例如,如图6所示,信号源界面中可以包括电视直播(同轴电缆接口)选项、HDMI1选项、HDMI2选项、USB选项以及投屏选项等。用户可以通过控制装置100上的方向键,控制信号源界面中的焦点光标在多个接口选项之间进行移动,从而在焦点光标移动至任一接口选项位置后,通过按下“确认”键,控制显示设备200播放选中接口对应的信号源内容。例如,当用户想要观看电视直播时,可以控制焦点光标移动至电视直播选项,并按下“确认”键,从而控制显示设备200通过同轴电缆接口从数字电视信号线中获取电视直播信号,并通过显示器260呈现电视直播信号中对应的画面。The signal source interface can provide users with operations such as signal source selection and switching. Therefore, multiple interface options can be set in the signal source interface. For example, as shown in FIG. 6 , the signal source interface may include live TV (coaxial cable interface) options, HDMI1 options, HDMI2 options, USB options, and screen projection options. The user can control the focus cursor in the signal source interface to move between multiple interface options through the direction keys on thecontrol device 100, so that after the focus cursor moves to any interface option position, by pressing the "confirm" key, Thedisplay device 200 is controlled to play the signal source content corresponding to the selected interface. For example, when the user wants to watch live TV, he can control the focus cursor to move to the live TV option, and press the "confirm" key, so as to control thedisplay device 200 to obtain the live TV signal from the digital TV signal line through the coaxial cable interface, And the corresponding picture in the live TV signal is presented through thedisplay 260 .

可见,当显示设备200上的接口数量较多时,信号源界面中包含的接口选项数量也较多,为了便于用户进行信号源切换,在一些实施例中,显示设备200可以对信号源界面中的每个接口选项进行标记,以便用户区分不同的信号源。例如,如图7所示,在同轴电缆接口连接数字电视信号线以后,显示设备200可以将该接口的名称更改为“电视直播”,以表征其接入的信号源。同理,当HDMI1接口连接游戏设备时,显示设备200可以支持用户手动设置,将HDMI1接口的名称更改为“游戏机”。It can be seen that when the number of interfaces on thedisplay device 200 is large, the number of interface options included in the signal source interface is also large. In order to facilitate the user to switch signal sources, in some embodiments, thedisplay device 200 can select the Each interface option is labeled so that users can distinguish between different signal sources. For example, as shown in FIG. 7 , after the coaxial cable interface is connected to a digital TV signal line, thedisplay device 200 may change the name of the interface to "live TV" to represent the signal source connected to it. Similarly, when the HDMI1 interface is connected to a game device, thedisplay device 200 can support manual setting by the user to change the name of the HDMI1 interface to "game console".

通过修改接口选项的名称,可以使显示设备200显示的信号源界面便于用户对接口选项进行分辨。但用户在使用显示设备200时,可以更改外部装置接口240的连接目标,例如,将HDMI1接口从连接游戏机更改为连接个人计算机(Personal Computer,PC)。此时,由于接口连接的目标已更改,显示设备200需要同步修改信号源界面中对应的选项名称,即用户需要将HDMI1接口选项名称从“游戏机”修改为“PC”。By modifying the name of the interface option, the signal source interface displayed on thedisplay device 200 can facilitate the user to distinguish the interface option. However, when using thedisplay device 200 , the user can change the connection destination of theexternal device interface 240 , for example, change the HDMI1 interface from being connected to a game console to being connected to a personal computer (Personal Computer, PC). At this time, since the target of the interface connection has been changed, thedisplay device 200 needs to simultaneously modify the corresponding option name in the signal source interface, that is, the user needs to change the HDMI1 interface option name from "game console" to "PC".

上述接口选项名称的修改过程,可以由用户根据实际接口连接目标手动修改完成,也可以由显示设备200通过识别该接口对应的信号类型和画面特点自动修改完成。例如,显示设备200可以内置图像识别程序,在外部装置接口240接收到音视频数据后,显示设备200可以从音视频数据中进行图像采样,并调用图像识别程序对采样获得的图像进行图像识别,图像识别程序可以通过光学特征文字识别(Optical Character Recognition,OCR)或机器学习模型对图像中的包含的特征进行识别,从而确定图像归属的信号源类型,进而根据信号源类型修改接口选项的名称。The modification process of the interface option name above can be completed manually by the user according to the actual interface connection target, or can be automatically modified by thedisplay device 200 by identifying the signal type and screen characteristics corresponding to the interface. For example, thedisplay device 200 can have a built-in image recognition program. After theexternal device interface 240 receives the audio and video data, thedisplay device 200 can perform image sampling from the audio and video data, and call the image recognition program to perform image recognition on the sampled image. The image recognition program can identify the features contained in the image through Optical Character Recognition (OCR) or machine learning model, so as to determine the type of signal source to which the image belongs, and then modify the name of the interface option according to the type of signal source.

但是由于显示设备200能够接入的信号源类型数量众多,且部分信号源所提供的音视频内容并不具有特异性,例如,当显示设备200接入的信号源为电视直播信号时,电视直播信号可以根据不同的频道、不同时段播放不同的电视内容,播放的电视内容可以包括电影、电视剧、广告、新闻、体育比赛、游戏直播等多种画面形式,这些画面形式之间往往难以具有相同的画面特征,因此通过显示设备200的图像识别方法,较难确定其准确的信号源类型,导致添加的接口选项名称出现错误。However, due to the large number of types of signal sources that thedisplay device 200 can access, and the audio and video content provided by some signal sources is not specific, for example, when the signal source connected to thedisplay device 200 is a live TV signal, the live TV The signal can play different TV content according to different channels and time periods. The TV content played can include movies, TV dramas, advertisements, news, sports games, live games and other picture forms. It is often difficult for these picture forms to have the same Therefore, it is difficult to determine the exact signal source type through the image recognition method of thedisplay device 200, resulting in errors in the names of the added interface options.

为了便于使用户能够准确知晓各接口选项对应的信号源内容,在一些实施例中,显示设备200还可以在信号源界面中添加与各外部装置接口240相关联的内容展示窗口。即如图8所示,接口选项可以由内容展示窗口和接口名称构成。根据显示设备200的UI布局特点,内容展示窗口可以与接口名称之间保持特定的相互位置关系。例如,内容展示窗口可以位于接口名称的上方。In order to enable the user to accurately know the signal source content corresponding to each interface option, in some embodiments, thedisplay device 200 may also add a content display window associated with eachexternal device interface 240 in the signal source interface. That is, as shown in FIG. 8 , the interface options may consist of a content display window and an interface name. According to the UI layout characteristics of thedisplay device 200, the content display window and the interface name may maintain a specific mutual positional relationship. For example, the content display window can be located above the interface name.

内容展示窗口可以通过图片、动态图、短视频或实时视频播放等形式对当前接口对应的信号源内容进行展示。具体展示的内容可以通过对当前接口对应信号源进行截图或提取获得。例如,在显示设备200通过同轴电缆接口连接电视直播信号线时,显示设备200可以对电视直播信号线传递的视频数据进行提取,以从中获取至少一帧预览图像,再将预览图像添加在内容展示窗口中,以通过预览图像对当前接口选项对应的电视直播信号源进行展示。The content display window can display the content of the signal source corresponding to the current interface in the form of pictures, dynamic pictures, short videos or real-time video playback. The specific displayed content can be obtained by taking a screenshot or extracting the signal source corresponding to the current interface. For example, when thedisplay device 200 is connected to the live TV signal line through the coaxial cable interface, thedisplay device 200 can extract the video data transmitted by the live TV signal line to obtain at least one frame of preview image, and then add the preview image to the content In the display window, the live TV signal source corresponding to the current interface option is displayed through the preview image.

内容展示窗口中显示的内容,还可以通过其他方式获得,并随着用户的使用过程进行更新。例如,对于电视直播信号源,显示设备200可以根据当前时间,向服务器400发送请求,服务器400在接收到请求后,可以根据请求中的当前时间,确定电视直播信号的当前播出进度,从而根据播放进度匹配相应的预览图像。The content displayed in the content display window can also be obtained in other ways, and is updated along with the user's use process. For example, for a live TV signal source, thedisplay device 200 can send a request to theserver 400 according to the current time, and after receiving the request, theserver 400 can determine the current broadcast progress of the live TV signal according to the current time in the request, so as to The playback progress matches the corresponding preview image.

其中,预览图像可以是服务器400根据电视直播信号中默认频道的播出列表生成。即服务器400可以根据默认频道的播出列表,获取各时段对应的具有代表性的图像,作为预览图像。例如,如图8所示,当电视直播信号的默认频道“×TV-1”在上午7:00-9:00时段播出新闻节目,在上午9:00-11:00播出电视剧《A》时,则显示设备200可以获取新闻节目封面作为本时段的预览图像,从而当用户在7:00-9:00时段控制显示设备200显示信号源界面时,可以在信号源界面的电视直播接口显示新闻封面。同理,当用户在9:00-11:00时段控制显示设备200显示信号源界面时,显示设备200可以获取电视剧《A》的封面作为预览图像,从而在信号源界面的电视直播接口显示电视剧《A》的封面。Wherein, the preview image may be generated by theserver 400 according to the broadcast list of the default channel in the live TV signal. That is, theserver 400 may acquire representative images corresponding to each time period as preview images according to the broadcast list of the default channel. For example, as shown in Figure 8, when the default channel "×TV-1" of the live TV signal broadcasts a news program at 7:00-9:00 in the morning, and broadcasts a TV series "A TV-1" at 9:00-11:00 in the morning. ", thedisplay device 200 can obtain the cover of the news program as the preview image of this period, so that when the user controls thedisplay device 200 to display the signal source interface at 7:00-9:00, the live TV interface of the signal source interface can Show news cover. Similarly, when the user controls thedisplay device 200 to display the signal source interface during the time period of 9:00-11:00, thedisplay device 200 can obtain the cover of the TV series "A" as a preview image, thereby displaying the TV series on the live TV interface of the signal source interface The cover of "A".

内容展示窗口还可以根据显示设备200的硬件配置和接入情况,呈现为不同的形式。例如,对于硬件配置和网络状况良好的显示设备200,内容展示窗口可以通过短视频或实时视频播放的形式显示信号源内容。而对于硬件配置和网络状况一般的显示设备200,内容展示窗口可以通过图片或动图的形式对信号源内容进行展示。The content presentation window may also be presented in different forms according to the hardware configuration and access conditions of thedisplay device 200 . For example, for thedisplay device 200 with good hardware configuration and network conditions, the content display window can display the content of the signal source in the form of short video or real-time video playback. For thedisplay device 200 with general hardware configuration and network conditions, the content display window can display the content of the signal source in the form of pictures or animations.

在一些实施例中,显示设备200还可以根据当前计算资源消耗情况,动态调整信号源界面中内容展示窗口的预览图像展示形式。即在显示设备200中可以内置内存监控模块用于实时监控显示设备200的内存使用量,当显示设备200的内存使用量超过内存阈值时,可以采用图片或动态图片的形式在内容展示窗口显示预览图像,以减少对内存资源的占用;当显示设备200的内存使用量未超过内存阈值时,可以采用短视频或实时视频播放的形式在内容展示窗口显示预览图像,以获得更好的内容展示效果。In some embodiments, thedisplay device 200 may also 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 can be built in thedisplay device 200 for real-time monitoring of the memory usage of thedisplay device 200. When the memory usage of thedisplay device 200 exceeds the memory threshold, a preview can be displayed in the content display window in the form of pictures or dynamic pictures image, to reduce the occupation of memory resources; when the memory usage of thedisplay device 200 does not exceed the memory threshold, the preview image can be displayed in the content display window in the form of short video or real-time video playback, so as to obtain better content display effect .

由于显示设备200上可以设置有多种接口,每种接口可以根据其具体的连接方式,接入不同的信号源,因此在显示设备200呈现的信号源界面中通常包括多个接口选项,并且多个接口选项中的内容展示窗口均可以呈现当前信号源对应的预览图像内容。为了控制内容展示窗口中具体的预览图像内容,在本申请的部分实施例中,显示设备200可以内置信号源界面显示方法,当用户控制显示设备200显示信号源界面时,显示设备200可以通过运行该信号源界面显示方法,控制内容展示窗口中的具体内容。Since thedisplay device 200 can be provided with multiple interfaces, and each interface can be connected to different signal sources according to its specific connection mode, the signal source interface presented by thedisplay device 200 usually includes multiple interface options, and more The content display window in each interface option can present the 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, thedisplay device 200 can have a built-in signal source interface display method. When the user controls thedisplay device 200 to display the signal source interface, thedisplay device 200 can run the The signal source interface display method controls the specific content in the content display window.

相应的,为了使显示设备200能够运行该信号源界面显示方法,显示设备200应至少包括显示器260、外部装置接口240以及控制器250。其中,显示器260用于显示包括信号源界面在内的多种用户界面。外部装置接口240可以具有特定的接口规范,用于连接不同的设备或线路,以连接多个信号源。如图9所示,控制器250则可以被配置为执行上述信号源界面显示方法,具体包括以下内容:Correspondingly, in order for thedisplay device 200 to run the signal source interface display method, thedisplay device 200 should at least include adisplay 260 , anexternal device interface 240 and acontroller 250 . Wherein, thedisplay 260 is used for displaying various user interfaces including the signal source interface. Theexternal device interface 240 may have a specific interface specification for connecting different devices or lines to connect multiple signal sources. As shown in FIG. 9, thecontroller 250 may be configured to execute the above method for displaying the signal source interface, which specifically includes the following content:

接收用户输入的用于显示信号源界面的控制指令。用户可以通过多种方式控制显示设备200显示信号源界面。即在一些实施例中,用户可以通过显示设备200配套的控制装置100控制显示信号源界面。例如,在控制装置100上可以设置有“信号源”按键,当用户按下“信号源”按键时,可以触发显示设备200从当前界面跳转至显示信号源界面。A control instruction for displaying a signal source interface input by a user is received. The user can control thedisplay device 200 to display the signal source interface in various ways. That is, in some embodiments, the user can control and display the signal source interface through thecontrol device 100 provided with thedisplay device 200 . For example, a "signal source" button may be provided on thecontrol device 100, and when the user presses the "signal source" button, thedisplay device 200 may be triggered to jump from the current interface to display the signal source interface.

在一些实施例中,用户还可以基于显示设备200提供的UI交互界面操作,控制显示设备200跳转至信号源界面。例如,用户可以通过控制装置100上的方向键控制用户界面中的焦点光标移动,当焦点光标移动至当前画面最顶部的选项位置再按下“上”方向键时,可以触发显示设备200显示状态栏,在状态栏中可以设有“信号源”选项,当用户控制焦点光标选中“信号源”选项,再按下“确认”键以后,显示设备200可以跳转至显示信号源界面。又例如,在显示设备200的控制主页和设置界面中,也可以设有“信号源”选项,当用户选中该选项后,可以控制显示设备200跳转至信号源界面。In some embodiments, the user can also control thedisplay device 200 to jump to the signal source interface based on the UI interaction interface operation provided by thedisplay device 200 . For example, the user can control the movement of the focus cursor in the user interface through the direction keys on thecontrol device 100. When the focus cursor moves to the topmost option position of the current screen and then presses the "up" direction key, thedisplay device 200 can be triggered to display the status The “Signal Source” option can be set in the status bar. When the user controls the focus cursor to select the “Signal Source” option and presses the “Enter” key, thedisplay device 200 can jump to the signal source display interface. For another example, in the control home page and setting interface of thedisplay device 200, there may also be a "signal source" option, and when the user selects this option, thedisplay device 200 may be controlled to jump to the signal source interface.

需要说明的是,显示设备200还可以根据所支持的其他交互方式完成显示信号源界面的控制指令的输入。例如,对于支持触控交互操作的显示设备200,用户可以通过触摸操作,选中状态栏、控制主页、设置界面中的“信号源”选项,从而获得与控制装置100按键操作功能相同的交互方式,即控制显示设备200跳转至信号源界面。对于支持智能语音交互的显示设备200,用户还可以在呼出智能语音助手后,通过输入语音“切换信号源”,控制显示设备200显示信号源界面。It should be noted that thedisplay device 200 may also complete the input of the control instruction for displaying the signal source interface according to other supported interaction modes. For example, for adisplay device 200 that supports touch interactive operations, the user can select the "signal source" option in the status bar, control homepage, and setting interface through touch operations, so as to obtain the same interaction mode as the button operation function of thecontrol device 100, That is, thedisplay device 200 is controlled to jump to the signal source interface. For thedisplay device 200 that supports intelligent voice interaction, the user can also control thedisplay device 200 to display the signal source interface by inputting the voice "switch signal source" after calling out the intelligent voice assistant.

在用户输入用于显示信号源界面的控制指令后,显示设备200可以响应于用户输入的控制指令,控制在显示器260中显示信号源界面。为了使用户能够准确识别信号源界面中各接口选项对应连接的信号源状况,在显示设备200显示的信号源界面中应包括多个接口选项,每个接口选项均可以包括一个与外部装置接口240相关联的内容展示窗口。After the user inputs a control instruction for displaying the signal source interface, thedisplay device 200 may control thedisplay 260 to display the signal source interface in response to the control instruction input by the user. In order to enable the user to accurately identify the signal source status corresponding to the connection of each interface option in the signal source interface, the signal source interface displayed on thedisplay device 200 should include multiple interface options, and each interface option can include anexternal device interface 240 The associated content display window.

因此,在显示信号源界面前,显示设备200可以根据信号源界面显示方法对应的程序,对内容展示窗口具体显示的内容进行展示。即显示设备200可以获取外部装置接口的预览图像。其中,所述预览图像为根据外部装置接口240连接的信号源预先保存的显示画面。具体可以是在前一次切出外部装置接口240的信号源时预先保存的显示画面,或者针对外部装置接口240的信号源在特定时间点进行画面提取而预先保存的显示画面,或者针对上一次该外部装置接口240进行播放时的显示画面进行截图获得的图像。Therefore, before displaying the signal source interface, thedisplay 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, thedisplay apparatus 200 may acquire a preview image of the external device interface. Wherein, the preview image is a display screen saved in advance according to a signal source connected to theexternal device interface 240 . Specifically, it may be the display screen saved in advance when the signal source of theexternal device interface 240 was switched out last time, or the display screen previously saved for the signal source of theexternal device interface 240 at a specific time point for image extraction, or the display screen for the last time the signal source of theexternal device interface 240 The image obtained by screenshotting the display screen when theexternal device interface 240 is playing.

根据显示设备200所具体呈现的预览图像画面形式的不同,显示设备200响应于控制指令所获取的预览图像形式也不同。例如,当设定内容展示窗口显示的预览图像形式为图片时,显示设备200可以获取图片形式的预览图像;当设定内容展示窗口显示的预览图像形式为短视频时,显示设备200可以获取当前信号源对应的短视频文件。According to the different forms of preview image screens specifically presented by thedisplay device 200, the preview image forms acquired by thedisplay device 200 in response to the control instruction are also different. For example, when the format of the preview image displayed in the content display window is set to be a picture, thedisplay device 200 can obtain the preview image in the form of a picture; when the format of the preview image displayed in the content display window is set to be a short video, thedisplay device 200 can obtain the current The short video file corresponding to the signal source.

在获取预览图像后,显示设备200再将预览图像添加至内容展示窗口,并与接口名称等内容组成接口选项。当信号源界面中包括多个接口选项时,显示设备200可以逐一获取每个接口选项(即外部装置接口240)对应的预览图像,并将获取的预览图像添加至内容展示窗口,从而形成最终的信号源界面。最后,显示设备200的控制器250可以控制显示器260显示信号源界面。After acquiring the preview image, thedisplay device 200 adds the preview image to the content display window, and forms an interface option together with content such as the interface name. When the signal source interface includes multiple interface options, thedisplay device 200 can acquire the preview image corresponding to each interface option (ie, the external device interface 240 ) one by one, and add the acquired preview image to the content display window to form the final Signal source interface. Finally, thecontroller 250 of thedisplay device 200 can control thedisplay 260 to display the signal source interface.

例如,如图10所示,当显示设备200上包括同轴电缆接口、HDMI1接口、HDMI2接口,并分别连接电视直播信号线、游戏设备、PC时,显示设备200可以在信号源界面中显示电视直播选项、HDMI1选项和HDMI2选项。并且在用户输入用于显示信号源界面的控制指令后,响应于该控制指令,分别获取同轴电缆接口、HDMI1接口和HDMI2接口对应的预览图像,即电视直播画面截图、游戏封面和个人电脑桌面图案。再将电视直播画面截图添加至电视直播选项的内容展示窗口中,将游戏封面添加至HDMI1选项的内容展示窗口中,将个人电脑桌面图案添加至HDMI2选项,形成最终的信号源界面显示在显示器260上。For example, as shown in FIG. 10, when thedisplay device 200 includes a coaxial cable interface, an HDMI1 interface, and an HDMI2 interface, and is respectively connected to a live TV signal line, a game device, and a PC, thedisplay device 200 can display the TV on the signal source interface. Live option, HDMI1 option and HDMI2 option. And after the user inputs the control command for displaying the signal source interface, in response to the control command, the preview images corresponding to the coaxial cable interface, the HDMI1 interface and the HDMI2 interface are obtained respectively, that is, the screenshot of the live TV screen, the cover of the game and the desktop of the personal computer. pattern. Then add the screenshot of the live TV screen to the content display window of the TV live option, add the game cover to the content display window of the HDMI1 option, and add the PC desktop pattern to the HDMI2 option to form the final signal source interface displayed on themonitor 260 superior.

在一些实施例中,为了在信号源界面中呈现内容展示窗口,显示设备200可以通过多个图层叠加的方式获得信号源界面的最终显示效果。例如,显示设备200在渲染信号源界面的过程中可以设置三个图层,即视频(Video)层、菜单控制(On-Screen Display,OSD)层和画面组(Group Of Pictures,GOP)层。在获取用于显示信号源界面的控制指令后,显示设备200可以根据操作系统的UI布局策略,在UI模板库中提取信号源界面的显示模板,并通过Video层形成初始的信号源界面。其中,Video层上的初始信号源界面不包含内容展示窗口。In some embodiments, in order to present a content display window on the signal source interface, thedisplay device 200 may obtain the final display effect of the signal source interface by superimposing multiple layers. For example, thedisplay device 200 may set three layers in the process of rendering the signal source interface, namely a video (Video) layer, a menu control (On-Screen Display, OSD) layer and a group of pictures (Group Of Pictures, GOP) layer. After obtaining the control instruction for displaying the signal source interface, thedisplay device 200 can extract the display template of the signal source interface from the UI template library according to the UI layout strategy 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 display window.

在渲染出Video层的初始信号源界面后,显示设备200可以根据Video层中各接口选项所在的位置,在OSD层添加内容展示窗口。每个内容展示窗口的位置与Video层中接口选项所在位置相关联,以使其在视觉上可以获得图层叠加效果。After rendering the initial signal source interface of the Video layer, thedisplay device 200 may add a content display window on the OSD layer according to the positions of the interface options in the Video layer. The position of each content display window is associated with the position of the interface option in the Video layer, so that it can obtain a layer overlay effect visually.

在渲染OSD层以后,显示设备200还可以根据OSD层中各内容展示窗口的位置,在GOP层规划处多个用于显示预览图像的区域,从而在显示设备200获取每个外部装置接口240对应信号源的预览图像后,在划定的区域内显示每个内容展示窗口对应的预览图像。可见,通过Video层、OSD层以及GOP层的叠加,可以获得最终的信号源界面,通过多个图层的叠加,可以使信号源界面中包括内容展示窗口以及在内容展示窗口中显示的预览图像。After rendering the OSD layer, thedisplay device 200 can also plan multiple areas for displaying preview images at the GOP layer according to the positions of the content display windows in the OSD layer, so that thedisplay device 200 can obtain the corresponding information of eachexternal device interface 240. After the preview image of the signal source, the preview image corresponding to each content display window is displayed in the designated area. It can be seen that the final signal source interface can be obtained through the superposition of the Video layer, OSD layer and GOP layer, and the signal source interface can include a content display window and a preview image displayed in the content display window through the superposition of multiple layers .

由以上技术方案可知,上述信号源界面显示方法可以在用户输入控制指令后,自动获取根据每个外部装置接口240连接信号源预先保存的预览图像,并将获取的预览图像添加至每个接口选项对应的内容展示窗口中,从而对各接口的当前信号源进行展示,便于用户通过预览图像分辨每个信号源,了解各信号源对应的内容,从而根据自身需要控制显示设备200切换至指定的信号源。It can be seen from the above technical solution that the above signal source interface display method can automatically obtain the preview image pre-saved according to eachexternal device interface 240 connected to the signal source after the user inputs the control command, and add the obtained preview image to each interface option In the corresponding content display window, the current signal source of each interface is displayed, which is convenient for users to distinguish each signal source through the preview image, understand the content corresponding to each signal source, and thus control thedisplay device 200 to switch to the specified signal according to their own needs. source.

由于显示设备200中可以包括多个外部装置接口240,并且多个外部装置接口240可以具有不同的连接状态,例如,HDMI1接口在连接游戏设备的同时,HDMI2接口未连接任何设备或信号线路。因此,显示设备200还可以在显示信号源界面的过程中,根据连接状态调整每个接口选项的显示形式。即如图11所示,在一些实施例中,显示设备200还可以在获取接口选项的预览图像前,检测每个外部装置接口240的连接状态。Since thedisplay device 200 may include multiple external device interfaces 240, and the multiple external device interfaces 240 may have different connection states, for example, the HDMI1 interface is connected to a game device while the HDMI2 interface is not connected to any device or signal line. Therefore, thedisplay device 200 may also adjust the display form of each interface option according to the connection state during the process of displaying the signal source interface. That is, as shown in FIG. 11 , in some embodiments, thedisplay device 200 may also detect the connection status of eachexternal device interface 240 before acquiring the preview image of the interface options.

其中,所述连接状态包括接入状态和未接入状态。显示设备200可以通过检测外部装置接口240的信号输入情况、热插拔电压变化等参数确定当前外部装置接口240是否接入线路或设备。当检测到当前外部装置接口240有信号输入,或者热插拔电压处于高电位时,确定当前外部装置接口240的连接状态为接入状态;反之,当检测到当前外部装置接口240无信号输入,且热插拔电压处于低电位时,确定当前外部装置接口240的连接状态为未接入状态。Wherein, the connection state includes an access state and a non-access state. Thedisplay device 200 can determine whether theexternal device interface 240 is currently connected to a line or device by detecting parameters such as signal input conditions of theexternal device interface 240 and changes in hot plug voltage. When it is detected that the currentexternal device interface 240 has a signal input, or when the hot plug voltage is at a high potential, it is determined that the connection state of the currentexternal device interface 240 is an access state; otherwise, when it is detected that the currentexternal device interface 240 has no signal input, And when the hot plug voltage is at a low potential, it is determined that the current connection state of theexternal device interface 240 is not connected.

显示设备200可以根据每个外部装置接口240的连接状态,采用相适应的方式显示接口选项。即如果外部装置接口240处于接入状态,则显示设备200可以按照上述实施例的方式执行获取外部装置接口240的预览图像的步骤,并将预览图像添加至内容展示窗口,形成带有预览图像画面接口选项以及信号源界面显示在显示器260中。Thedisplay device 200 may display interface options in an appropriate manner according to the connection state of eachexternal device interface 240 . That is, if theexternal device interface 240 is in the connected state, thedisplay device 200 can perform the step of obtaining the preview image of theexternal device interface 240 according to the above-mentioned embodiment, and add the preview image to the content display window to form a screen with a preview image. Interface options and source interfaces are displayed ondisplay 260 .

如果外部装置接口240处于未接入状态,则显示设备200可以跳过获取预览图像的步骤,而是在内容展示窗口中添加默认图标。默认图标可以根据接口具体形式,以图案、文字及其组合形成。由于未接入状态的外部装置接口240通常无法为显示设备200提供具体的显示画面或音频内容,因此为了引导用户不选择该接口选项,显示设备200还可以控制显示器260通过灰度图案显示内容展示窗口。If theexternal device interface 240 is not connected, thedisplay device 200 may skip the step of acquiring the preview image, but add a default icon in the content display window. The default icon can be formed by patterns, characters and combinations thereof according to the specific form of the interface. Since theexternal device interface 240 in the unconnected state usually cannot provide specific display images or audio content for thedisplay device 200, in order to guide the user not to select the interface option, thedisplay device 200 can also control thedisplay 260 to display the content display through a grayscale pattern. window.

例如,如图12所示,通过检测外部装置接口240的连接状态,确定当前显示设备200各外部装置接口240的连接状态分别为:同轴电缆接口为接入状态,HDMI1接口为接入状态,HDMI2为未接入状态。则显示设备200可以针对同轴电缆接口和HDMI1接口执行获取预览图像等步骤,以通过内容展示窗口显示电视直播截图和游戏封面,展示同轴电缆接口和HDMI1接口的信号源内容。而对于HDMI2接口,显示设备200可以在内容展示窗口中添加代表HDMI接口形状的默认图标,并通过灰度显示该内容展示窗口,以表征HDMI2接口没有连接可用信号源的状态。For example, as shown in FIG. 12 , by detecting the connection status of theexternal device interface 240, it is determined that the connection status of eachexternal device interface 240 of thecurrent display device 200 is respectively: the coaxial cable interface is in the connected state, the HDMI1 interface is in the connected state, HDMI2 is not connected. Then thedisplay device 200 can perform steps such as obtaining preview images for the coaxial cable interface and HDMI1 interface, so as to display live TV screenshots and game covers through the content display window, and display the signal source content of the coaxial cable interface and HDMI1 interface. For the HDMI2 interface, thedisplay device 200 may add a default icon representing the shape of the HDMI interface in the content display window, and display the content display window in grayscale to represent the state that the HDMI2 interface is not connected to an available signal source.

可见,在上述实施例中,显示设备200可以在信号源界面中,通过不同的接口选项显示形式,对该选项对应外部装置接口240的连接状态进行展示,即置灰的信号源代表该通道为空,未接入设备或信号线路、高亮的信号源代表该通道已经接入设备或信号线路,并通过预览图像展示对应的信号源内容。It can be seen that in the above-mentioned embodiment, thedisplay device 200 can display the connection status of theexternal device interface 240 corresponding to the option through different interface option display forms in the signal source interface, that is, the signal source that is grayed out represents that the channel is Empty, no device or signal line is connected, and the highlighted signal source means that the channel has been connected to the device or signal line, and the corresponding signal source content is displayed through the preview image.

由于显示设备200中可以包括多个外部装置接口240,并且多个外部装置接口240可以连接不同的设备或者信号线路,因此信号源界面中需要显示多个接口选项。多个接口选项可以按照使用频率等排列规则,设定其在信号源界面中的显示顺序。例如,信号源界面中接口选项的默认显示顺序为:直播电视接口、HDMI(1,2,3…)接口、分量接口、音视频接口、视频图形阵列(Video Graphics Array,VGA)接口、数字视频(Digital VisualInterface,DVI)接口、USB-typeC接口、USB接口、数字生活网络联盟(Digital LivingNetwork Alliance,DLNA)接口。多个接口选项可以按照上述顺序,并以一字形排列或矩形阵列方式排列,方便用户通过较少次数的按下控制装置100方向键,选中经常播放的信号源。Since thedisplay device 200 may include multiple external device interfaces 240, and the multiple external device interfaces 240 may be connected to different devices or signal lines, therefore multiple interface options need to be displayed on the signal source interface. Multiple interface options can be set in the order of display in the signal source interface according to the arrangement rules such as frequency of use. For example, the default display order of interface options in the signal source interface is: live TV interface, HDMI (1,2,3...) interface, component interface, audio and video interface, video graphics array (Video Graphics Array, VGA) interface, digital video (Digital Visual Interface, DVI) interface, USB-type C interface, USB interface, Digital Living Network Alliance (Digital Living Network Alliance, DLNA) interface. The multiple interface options can be arranged in a straight line or in a rectangular array according to the above order, so that the user can select frequently played signal sources by pressing the direction keys of thecontrol device 100 less times.

在信号源界面中展示多个接口选项时,显示设备200可以根据每个接口选项对应外部装置接口240的接入状态对接口选项的排列顺序进行调整,以方便用户快速选择有效的信号源。在一些实施例中,当内容展示窗口在信号源界面中呈一字形排列时,显示设备200可以遍历外部装置接口240的连接状态,并根据连接状态计算内容展示窗口的排列优先级。再根据排列优先级调整内容展示窗口在信号源界面中的排列顺序。When displaying multiple interface options on the signal source interface, thedisplay device 200 can adjust the arrangement order of the interface options according to the access state of theexternal device interface 240 corresponding to each interface option, so as to facilitate the user to quickly select an effective signal source. In some embodiments, when the content display windows are arranged in a line on the signal source interface, thedisplay device 200 may traverse the connection status of theexternal device interface 240, and calculate the arrangement priority of the content display windows according to the connection status. Then adjust the arrangement order of the content display window in the signal source interface according to the arrangement priority.

其中,计算获得的排列优先级中,处于接入状态的内容展示窗口高于处于未接入状态的内容展示窗口。为了计算所述排列优先级,显示设备200可以在默认排列顺序的基础上通过加值运算计算优先级。例如,显示设备200可以根据默认排列顺序为每个接口选项赋值,即默认排列在第一位的直播电视接口赋值为1、默认排列在第二位的HDMI1接口赋值为0.99、默认排列在第三位的HDMI2接口赋值为0.98……Wherein, in the arrangement priority obtained through calculation, the content display windows in the connected state are higher than the content display windows in the non-connected state. In order to calculate the sorting priority, thedisplay device 200 may calculate the priority based on the default sorting order through an added value operation. For example, thedisplay device 200 can assign a value to each interface option according to the default arrangement order, that is, the live TV interface that is arranged in the first place by default is assigned a value of 1, the HDMI1 interface that is arranged in the second place by default is assigned a value of 0.99, and the interface that is arranged in the third place by default is assigned a value of 0.99. Bit HDMI2 interface assignment is 0.98...

根据赋值结果,显示设备200再根据连接状态设置调整值,即接入状态的调整值为1,未接入状态的调整值为0。再针对调整值和默认赋值进行求和,即通过遍历各外部装置接口240的连接状态,可以确定当前处于接入状态的外部装置接口240分别为:直播电视接口、HDMI2接口和USB接口,则根据连接状态计算处于接入状态的直播电视接口对应优先级判断值为1+1=2,处于未接入状态的HDMI1接口对应优先级判断值为0.99+0=0.99。同理,根据上述计算方式,可以计算出HDMI2接口对应优先级判断值为0.98+1=1.98、USB接口对应优先级判断值为0.3+1=1.3。According to the assignment result, thedisplay device 200 sets an adjustment value according to the connection state, that is, the adjustment value is 1 for the connected state, and 0 for the unconnected state. Then sum the adjusted value and the default assignment, that is, by traversing the connection states of eachexternal device interface 240, it can be determined that the external device interfaces 240 currently in the access state are: live TV interface, HDMI2 interface and USB interface, then according to Connection status calculation The corresponding priority judgment value of the connected live TV interface is 1+1=2, and the corresponding priority judgment value of the unconnected HDMI1 interface is 0.99+0=0.99. Similarly, according to the above calculation method, it can be calculated that the priority judgment value corresponding to the HDMI2 interface is 0.98+1=1.98, and the priority judgment value corresponding to the USB interface is 0.3+1=1.3.

如图13所示,在计算每个接口对应的优先级判断值后,显示设备200可以根据优先级判断值由大至小的顺序,再次对接口选项的显示顺序进行调整,从而使处于接入状态的直播电视接口、HDMI2接口和USB接口排列在靠前的位置,以便用户可以通过较少次数的交互动作,即可选中可用的信号源。As shown in FIG. 13 , after calculating the priority judgment value corresponding to each interface, thedisplay device 200 can adjust the display order of the interface options again according to the order of the priority judgment value from large to small, so that the access The state-of-the-art live TV interface, HDMI2 interface and USB interface are arranged in the front position, so that users can select available signal sources through fewer interactions.

需要说明的是,在根据连接状态调整接口选项的显示顺序的过程中,显示设备200针对同处接入状态或同处未接入状态的外部装置接口240仍然维持默认显示顺序。例如,当直播电视接口、HDMI2接口和USB接口均处于接入状态时,显示设备200可以在将这三个接口选项显示在靠前位置后,仍然按照默认显示顺序,使直播电视接口处于第一位、HDMI2接口处于第二位、USB接口处于第三位的顺序,以便用户选择使用频率高、且当前有信号输入的接口作为信号源。It should be noted that during the process of adjusting the display order of the interface options according to the connection state, thedisplay device 200 still maintains the default display order for theexternal device interface 240 that is also in the connected state or in the same non-connected state. For example, when the live TV interface, the HDMI2 interface and the USB interface are all in the connected state, thedisplay device 200 can still make the live TV interface in the first position according to the default display order after displaying these three interface options at the front position. 1, the HDMI2 interface is in the second place, and the USB interface is in the third place, so that users can choose the interface with high frequency and current signal input as the signal source.

在设置接口选项的显示顺序后,显示设备200可以按照上述实施例中的方式,向接口选项对应的内容展示窗口添加预览图像,在一些实施例中,所述预览图像可以是用户在前一次切出该外部装置接口240时保存的显示画面。为此,显示设备200需要在每次切出当前信号源时,生成并保存预览图像。即如图14所示,显示设备200可以先获取用户输入的用于退出播放界面的退出指令。After setting the display order of the interface options, thedisplay device 200 can add a preview image to the content display window corresponding to the interface option according to the method in the above-mentioned embodiment. The display screen saved when theexternal device interface 240 is opened. For this reason, thedisplay device 200 needs to generate and save a preview image each time the current signal source is switched out. That is, as shown in FIG. 14 , thedisplay device 200 may first obtain an exit command input by the user for exiting the playback interface.

其中,用于退出播放界面的退出指令也可以类似于上述实施例中用于显示信号源界面的控制指令的输入方式,通过控制装置100上的按键、显示设备200操作的系统的UI界面、触控交互操作以及智能语音交互等方式进行输入。例如,用户可以在显示设备200显示播放界面时,通过按下控制装置100上的“退出”键,控制切出当前信号源。Wherein, the exit instruction for exiting the playback interface may also be similar to the input method of the control instruction for displaying the signal source interface in the above-mentioned embodiments, through the buttons on thecontrol device 100, the UI interface of the system operated by thedisplay device 200, the touch Control interactive operation and intelligent voice interaction for input. For example, when thedisplay device 200 is displaying the playback interface, the user can control to cut out the current signal source by pressing the "exit" key on thecontrol device 100 .

在交互过程中,由于显示设备200通常只能播放一个信号源对应的音视频数据,因此当用户控制显示设备200切换至新的信号源时,即切出原信号源。此时,也代表用户输入了用于退出播放界面的退出指令。During the interaction process, since thedisplay device 200 can usually only play audio and video data corresponding to one signal source, when the user controls thedisplay device 200 to switch to a new signal source, the original signal source is cut out. At this time, it also means that the user has input an exit instruction for exiting the playing interface.

在获取退出指令后,显示设备200再响应于该退出指令,根据切出的原信号源音视频数据内容,生成预览图像。生成预览图像的方式可以包括对播放界面中显示画面执行截图,以生成预览图像;以及,从播放界面中显示画面对应的音视频数据提取切出时刻对应的一帧画面,以生成预览图像。在生成预览图像以后,显示设备200再将预览图像进行存储,从而下一次显示信号源界面时可以将存储的预览图像添加至内容展示窗口,完成信号源界面的显示。After acquiring the exit instruction, thedisplay device 200 responds to the exit instruction and generates a preview image according to the clipped audio and video data content of the original signal source. The method of generating the preview image may include taking a screenshot of the display screen in the playback interface to generate the preview image; and extracting a frame corresponding to the cut-out time from the audio and video data corresponding to the display screen in the playback interface to generate the preview image. After the preview image is generated, thedisplay 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.

由于显示设备200上的外部装置接口240可以连接多种设备,其中,部分接口可以根据连接设备的不同具有不同的形式。例如,对于USB接口,在部分使用环境下是用来传递文件、数据、程序等通用数据的,即不作为信号源。而在部分使用环境下,显示设备200也可以通过USB接口连接智能终端等设备,以传递音视频数据,即作为信号源。而对于HDMI接口、同轴电缆接口等,通常仅用于传递音视频数据,即一直作为信号源。为了便于描述,本申请将一直作为信号源的接口称为第一类接口,将部分环境作为信号源,部分环境不作为信号源的接口称为第二类接口。Since theexternal device interface 240 on thedisplay device 200 can be connected to various devices, some of the interfaces can have different forms according to different connected devices. For example, for the USB interface, it is used to transfer common data such as files, data, and programs in some usage environments, that is, it is not used as a signal source. In some usage environments, thedisplay device 200 can also be connected to devices such as smart terminals through a USB interface to transmit audio and video data, that is, as a signal source. As for the HDMI interface, coaxial cable interface, etc., they are usually only used to transmit audio and video data, that is, they are always used as signal sources. For ease of description, in this application, the interface that always serves as a signal source is called the first type of interface, and the interface that uses part of the environment as a signal source and part of the environment as a signal source is called a second type of interface.

在显示信号源界面的过程中,对于第二类接口,显示设备200可以根据其连接状态控制其是否在信号源界面对应的内容展示窗口,以减少信号源界面中的内容展示窗口数量,简化界面内容。即如图15所示,在一些实施例中,显示设备200可以在获取接口选项的预览图像的步骤前,遍历外部装置接口240的接口类型。其中,接口类型包括用于传递音视频数据的第一类接口和用于传递通用数据的第二类接口。In the process of displaying the signal source interface, for the second type of interface, thedisplay device 200 can control whether it is in the content display window corresponding to the signal source interface according to its connection status, 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, thedisplay device 200 may traverse the interface types of theexternal device interface 240 before the step of obtaining the preview image of the interface options. Wherein, the interface type includes a first-type interface for transmitting audio and video data and a second-type interface for transmitting general data.

根据接口类型的遍历结果,如果外部装置接口240的接口类型为第一类接口,执行获取外部装置接口240的预览图像的步骤,即按照上述实施例中的信号源界面显示方式,通过获取预览图像以及向内容展示窗口中添加预览图像的方式,进行信号源界面显示。According to the traversal result of the interface type, if the interface type of theexternal device interface 240 is the first type interface, perform the step of obtaining the preview image of theexternal device interface 240, that is, according to the signal source interface display mode in the above-mentioned embodiment, by obtaining the preview image And a method of adding a preview image to the content display window to display the signal source interface.

如果外部装置接口240的接口类型为第二类接口,检测第二类接口的连接状态,并在连接状态为未接入时,隐藏外部装置接口240对应的内容展示窗口。例如,通过检测外部装置接口240的接口类型,可以确定USB接口和DLNA接口为第二类接口,再通过检测USB接口和DLNA接口的连接状态,从而在USB接口和DLNA接口有设备接入后再展示于信号源界面中,未接入时则不做展示。If the interface type of theexternal device interface 240 is the second type interface, the connection status of the second type interface is detected, and when the connection status is not connected, the content display window corresponding to theexternal device interface 240 is hidden. For example, by detecting the interface type of theexternal device interface 240, it can 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, after the USB interface and the DLNA interface have equipment connected It is displayed on the signal source interface, and it is not displayed when it is not connected.

在一些实施例中,显示设备200在显示内容展示窗口的同时,还可以对该接口对应连接的设备名称进行显示,即在控制显示器260显示信号源界面的步骤中,获取外部装置接口240所连接设备的设备名称,并在信号源界面中内容展示窗口的关联区域显示设备名称。即对于有信号接入的外部装置接口240,显示设备200可以将接口名称替换为需要展示信号源设备的名称。In some embodiments, while displaying the content display window, thedisplay device 200 can also display the name of the device connected to the interface, that is, in the step of controlling thedisplay 260 to display the signal source interface, thedevice interface 240 is connected to The device name of the device, and display the device name in the associated area of the content display window in the signal source interface. That is, for theexternal device interface 240 with signal access, thedisplay device 200 may replace the interface name with the name of the signal source device that needs to be displayed.

例如,在HDMI1接口连接游戏设备时,显示设备200可以通过读取HDMI1接口获得的设备信息帧数据,并从中读取设备类型,以确定当前接口连接游戏设备。再使用游戏设备对应的设备名称,如“游戏机”、“s-××(型号)游戏机”替换接口选项的原始名称“HDMI1”,形成新的接口选项,以便于用户理解和识别。For example, when the HDMI1 interface is connected to a game device, thedisplay device 200 can read the device information frame data obtained by the HDMI1 interface and read the device type from it to determine the game device currently connected to the interface. Then use the device name corresponding to the game device, such as "game console" and "s-XX (model) game console" to replace the original name "HDMI1" of the interface option to form a new interface option for users to understand and identify.

在一些实施例中,用户还可以通过特定的交互操作,对信号源界面中的内容展示窗口进行控制,以控制实时播放对应的信号源内容。即如图16所示,显示设备200可以在控制显示器260显示信号源界面后,检测信号源界面中焦点光标在内容展示窗口上的停留时长。检测的停留时长可以用来与预先设置的时长阈值进行对比,当停留时长大于时长阈值时,即确定用户想要通过内容展示窗口实时播放对应信号源内容,因此显示设备200可以获取内容展示窗口对应外部装置接口240接收的媒资数据,并在内容展示窗口播放媒资数据。In some embodiments, the user can also control the content display window in the signal source interface through specific interactive operations, so as to control real-time playback of the corresponding signal source content. That is, as shown in FIG. 16 , after thedisplay device 200 controls thedisplay 260 to display the signal source interface, it can detect how long the focus cursor stays on the content display window in the signal source interface. The detected dwell time can be used to compare with the preset duration threshold. When the dwell time is greater than the duration threshold, it is determined that the user wants to play the corresponding signal source content in real time through the content display window. Therefore, thedisplay device 200 can obtain the content corresponding to the content display window. Theexternal device interface 240 receives the media asset data, and plays the media asset data in the content display window.

例如,如图17所示,根据用户的操作习惯,可以预先设置时长阈值为3s,即焦点光标停留在内容展示窗口3s以上时,可以触发显示设备200实时预览功能。基于此,如图18所示,当显示设备200检测到焦点光标位于电视直播接口3s以上时,可以获取电视直播接口对应的数字电视信号,并通过内容展示窗口对数字电视信号进行实时播放,以实时预览当前信号源内容。For example, as shown in FIG. 17 , according to the user's operating habits, the duration threshold can be set to 3s in advance, that is, when the focus cursor stays above the content display window for 3s, the real-time preview function of thedisplay device 200 can be triggered. Based on this, as shown in FIG. 18 , when thedisplay device 200 detects that the focus cursor is located above the live TV interface for 3s, it can acquire the digital TV signal corresponding to the live TV interface, and play the digital TV signal in real time through the content display window, so as to Preview the content of the current signal source in real time.

可见,通过控制焦点光标在各接口选项上停留时间的控制,用户可以在不切换显示设备200信号源的前提下,对每个接口当前内容进行预览,从而便于用户实施获悉每个接口当前的画面内容,提高用户信号源切换过程的准确率。It can be seen that by controlling the dwell time of the focus cursor on each interface option, the user can preview the current content of each interface without switching the signal source of thedisplay device 200, so that the user can easily know the current picture of each interface. Content, improve the accuracy of the user's signal source switching process.

在显示设备200通过内容展示窗口对各接口信号源内容进行预览的过程中,如果焦点光标一直处于一个接口选项上,则显示设备200可以一直实时播放该外部装置接口240对应的信号源内容。而在焦点光标从该接口选项上移走时,显示设备200则可以停止该内容展示窗口的内容播放,继续对其他接口选项进行停留时长的判断。When thedisplay device 200 previews the content of each interface signal source through the content display window, if the focus cursor is always on an interface option, thedisplay device 200 can always play the signal source content corresponding to theexternal device interface 240 in real time. When the focus cursor moves away from the interface option, thedisplay device 200 may stop playing the content in the content display window, and continue to judge the duration of other interface options.

在一些实施例中,对于特定的接口选项,当用户控制将焦点光标移走后,其内容展示窗口可以保留光标移走时刻的显示画面,作为预览图像,并显示在内容展示窗口中。即显示设备200可以获取用户输入的用于移动焦点光标的移动指令,并响应于该移动指令,在媒资数据中提取移动指令的输入时刻的末帧图像,最后将内容展示窗口中显示的内容替换为末帧图像。In some embodiments, for a specific interface option, when the user controls to move the focus cursor away, the content display window may retain the display image at the time the cursor is removed as a preview image and display it in the content display window. That is, thedisplay device 200 can acquire the movement instruction input by the user for moving the focus cursor, and in response to the movement instruction, extract the last frame image at the time of inputting the movement instruction from the media asset data, and finally display the content displayed in the window Replaced by the last frame image.

例如,如图19所示,用户控制焦点光标在电视直播接口上停留3s以上时,显示设备200可以在电视直播接口对应的内容展示窗口中实时播放电视直播画面。并且,当用户通过控制装置100上的“右”方向键将焦点光标移动至HDMI1接口选项上时,显示设备200可以停止电视直播接口选项中内容展示窗口的实时播放进程,并对HDMI1接口上光标停留时长进行判断,从而在停留时长超过3s时通过HDMI1接口对应的内容展示窗口实时播放HDMI1接口接收的信号源画面。For example, as shown in FIG. 19 , when the user controls the focus cursor to stay on the live TV interface for more than 3 seconds, thedisplay device 200 can display live TV images in real time in the 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 thecontrol device 100, thedisplay device 200 can stop the real-time playback process of the content display window in the live TV interface option, and control the cursor on the HDMI1 interface. The stay time is judged, so that when the stay time exceeds 3s, the signal source screen received by the HDMI1 interface is played in real time through the content display window corresponding to the HDMI1 interface.

在焦点光标移出电视直播接口选项的同时,显示设备200可以保留焦点光标移出时刻电视直播画面内容,即末帧图像,以作为预览图像。并且通过生成的预览图像替换电视直播接口对应的内容展示窗口中的内容。When the focus cursor moves out of the live TV interface option, thedisplay device 200 may retain the content of the live TV screen when the focus cursor moves out, that is, the last frame image, as a preview image. And the content in the content display window corresponding to the live TV interface is replaced by the generated preview image.
