具体实施方式Detailed ways
以下基于实施例对本申请进行描述，但是本申请并不仅仅限于这些实施例。在下文对本申请的细节描述中，详尽描述了一些特定的细节部分。对本领域技术人员来说没有这些细节部分的描述也可以完全理解本申请。为了避免混淆本申请的实质，公知的方法、过程、流程、元件和电路并没有详细叙述。The present application is described below based on examples, but the present application is not limited to these examples only. In the following detailed description of the application, some specific details are described in detail. Those skilled in the art can fully understand the present application without the description of these detailed parts. Well-known methods, procedures, procedures, components and circuits have not been described in detail in order to avoid obscuring the essence of this application.
此外，本领域普通技术人员应当理解，在此提供的附图都是为了说明的目的，并且附图不一定是按比例绘制的。Furthermore, those of ordinary skill in the art will appreciate that the drawings provided herein are for illustrative purposes and are not necessarily drawn to scale.
除非上下文明确要求，否则在说明书的“包括”、“包含”等类似词语应当解释为包含的含义而不是排他或穷举的含义；也就是说，是“包括但不限于”的含义。Unless clearly required by the context, words such as "including", "comprising" and the like in the specification should be construed in an inclusive rather than an exclusive or exhaustive sense; that is, in the sense of "including but not limited to".
在本申请的描述中，需要理解的是，术语“第一”、“第二”等仅用于描述目的，而不能理解为指示或暗示相对重要性。此外，在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。In the description of the present application, it should be understood that the terms "first", "second" and the like are used for descriptive purposes only, and should not be construed as indicating or implying relative importance. Also, in the description of this application, unless otherwise specified, "plurality" means two or more.
在相关技术中，用户可以通过控制目标终端将目标终端的显示画面共享给另一个终端A，以实现在终端A可以同步展示目标终端所显示的图像、文本、演示文稿等文件。In the related art, the user can control the target terminal to share the display screen of the target terminal with another terminal A, so that the terminal A can display the image, text, presentation and other files displayed by the target terminal synchronously.
然而，在屏幕共享过程中，由于客观原因可能会出现接受屏幕共享的终端A的显示画面不正常的问题。例如，由于目标终端和终端A的操作系统不同，可能会导致终端A即使接收到目标终端发送的数据也无法正常显示的问题。再例如，由于目标终端和终端A显示屏尺寸的不同，可能会导致终端A同步展示的内容出现偏移等问题。再例如，目标终端和终端A中应用程序的版本不同，目标终端和终端A所显示的显示画面会由于版本的不同而出现差异，进而可能会出现同步展示的内容无法同步至显示界面中相应的位置。However, during the screen sharing process, there may be a problem that the display screen of the terminal A that accepts the screen sharing is abnormal due to objective reasons. For example, since the operating systems of the target terminal and terminal A are different, it may cause a problem that terminal A cannot display the data sent by the target terminal normally even if it receives data from the target terminal. For another example, due to the difference in the size of the display screen of the target terminal and the terminal A, problems such as offset may occur in the content displayed by the terminal A synchronously. For another example, if the versions of the application programs in the target terminal and terminal A are different, the display screen displayed by the target terminal and terminal A will be different due to the different versions, and it may happen that the content displayed synchronously cannot be synchronized to the corresponding display interface in the display interface. Location.
因此，如何保证屏幕共享时各个终端均可以显示正常的画面是目前亟需解决的问题。Therefore, how to ensure that each terminal can display a normal picture during screen sharing is an urgent problem to be solved at present.
为了解决上述问题，本申请实施例提供一种同步显示方法，该方法可以应用至同步显示系统中的电子设备，其中，电子设备包括同步终端和服务器，同步终端可以是智能手机、平板电脑、个人计算机(Personal Computer，PC)或者虚拟现实(Virtual Reality，VR)设备等，服务器可以是单个服务器，也可以是以分布式方式配置的服务器集群，还可以是云服务器。其中，VR技术是基于计算机技术产生的电子信号，通过VR设备向用户展示三维模型、二维图像、视频的技术。In order to solve the above problem, an embodiment of the present application provides a synchronous display method, which can be applied to electronic equipment in a synchronous display system, wherein the electronic equipment includes a synchronization terminal and a server, and the synchronization terminal can be a smart phone, a tablet computer, a personal A computer (Personal Computer, PC) or a virtual reality (Virtual Reality, VR) device, etc., the server may be a single server, a server cluster configured in a distributed manner, or a cloud server. Among them, VR technology is a technology based on electronic signals generated by computer technology to display three-dimensional models, two-dimensional images and videos to users through VR equipment.
在本申请实施例中，同步终端包括目标终端，其中，目标终端为向服务器发送数据，并使得各同步终端中除目标终端以外的同步终端基于同步显示的终端。In the embodiment of the present application, the synchronization terminal includes a target terminal, wherein the target terminal is a terminal that sends data to the server, and makes the synchronization terminals other than the target terminal among the synchronization terminals based on the synchronization display.
如图1所示，图1为本申请实施例同步显示系统的示意图，该示意图包括：服务器11、目标终端12、同步终端13和同步终端14。As shown in FIG. 1 , FIG. 1 is a schematic diagram of a synchronous display system according to an embodiment of the present application. The schematic diagram includes: a
其中，服务器11、目标终端12、同步终端13和同步终端14可以通过图1所示的网络连接方式实现在线数据传输，在另一种情况下，服务器11、目标终端12、同步终端13和同步终端14也可以通过有线连接的方式实现数据传输。Among them, the
在本申请实施例中，目标终端可以是可操作且具有显示功能的终端，同步终端可以是具有显示功能的终端。例如，如图1所示，目标终端12为计算机设备，同步终端13为移动终端设备，同步终端14为VR设备。当然，图1中的目标终端和同步终端仅为本申请实施例的一种举例说明，在实际应用中，目标终端和同步终端也可以是其它类型的终端，例如平板电脑、智能显示屏等等，目标终端和同步终端的数量也不仅限于图1所示的数量。In this embodiment of the present application, the target terminal may be an operable terminal with a display function, and the synchronization terminal may be a terminal with a display function. For example, as shown in FIG. 1 , the
服务器11在与多个设备(目标终端12、同步终端13和同步终端14)进行通信连接之后，服务器11可以通过该通信连接接收目标终端12设备发送的数据，然后向同步终端13和同步终端14下发目标终端12发送的数据，以实现同步终端13和同步终端14可以与目标终端12同步显示。After the
具体的，为了保证屏幕共享时各个终端均可以显示正常的画面，同步显示系统中的服务器可以被配置为执行：向各同步终端广播编码同步图像，接收目标终端发送的触控坐标，并基于触控坐标和编码同步图像执行同步操作，以使得各同步终端中除目标终端以外的同步终端进行同步显示。Specifically, in order to ensure that each terminal can display a normal picture when the screen is shared, the server in the synchronous display system can be configured to: broadcast the encoded synchronous image to each synchronous terminal, receive the touch coordinates sent by the target terminal, and based on the touch A synchronization operation is performed on the control coordinates and the coded synchronization image, so that the synchronization terminals other than the target terminal among the synchronization terminals are synchronously displayed.
同步显示系统中的同步终端可以被配置为执行：接收编码同步图像。A sync terminal in a sync display system may be configured to perform: receive an encoded sync image.
同步显示系统中的目标终端可以被配置为执行：向服务器发送触控坐标，并执行控制指令。The target terminal in the synchronous display system can be configured to perform: send touch coordinates to the server, and execute control instructions.
其中，编码同步图像是指经过数字编码后的显示画面，其具有较小的数据体量。在数据传输过程中，由于编码同步图像占用的数据量较小，因此，传输编码同步图像所需的时间较少，传输的效率较高。在本申请实施例中，服务器通过向各同步终端广播编码同步图像，可以使得各同步终端接收到相同的显示画面图像并进行显示。The coded synchronization image refers to a digitally coded display image, which has a small data volume. In the process of data transmission, since the amount of data occupied by the coded synchronous image is small, the time required to transmit the coded synchronous image is less, and the transmission efficiency is higher. In the embodiment of the present application, the server broadcasts the encoded synchronization image to each synchronization terminal, so that each synchronization terminal can receive and display the same display screen image.
另外，编码同步图像还包括对应的坐标系，当目标终端接收到用户通过外接设备(例如鼠标、键盘等)或者点触操作(例如用户通过触摸显示屏、通过触控笔点击显示屏等)输入的控制指令后，可以确定控制指令对应的触控坐标，而该触控坐标即为编码同步图像对应坐标系中的坐标。In addition, the coded synchronous image also includes a corresponding coordinate system. When the target terminal receives the input from the user through an external device (such as a mouse, keyboard, etc.) or a touch operation (such as the user touches the display screen, clicks the display screen with a stylus, etc.) After the control command is generated, the touch coordinates corresponding to the control command can be determined, and the touch coordinates are the coordinates in the coordinate system corresponding to the coded synchronization image.
进而，当服务器接收到目标终端发送的触控坐标后，服务器可以基于触控坐标和编码同步图像的坐标系执行同步操作。例如，服务器可以将触控坐标所对应的操作还原至编码同步图像，并将还原操作后的编码同步图像发送至各同步终端，以使得各同步终端中除目标终端以外的同步终端进行同步显示。再例如，服务器也可以将触控坐标发送至各同步终端，以使得各同步终端中除目标终端以外的同步终端基于触控坐标和编码同步图像进行同步显示。Furthermore, after the server receives the touch coordinates sent by the target terminal, the server may perform a synchronization operation based on the touch coordinates and the coordinate system of the encoded synchronization image. For example, the server can restore the operation corresponding to the touch coordinates to the coded synchronous image, and send the coded synchronous image after the restoration operation to each synchronous terminal, so that the synchronous terminals other than the target terminal among the synchronous terminals can display synchronously. For another example, the server may also send the touch coordinates to each synchronization terminal, so that the synchronization terminals other than the target terminal among the synchronization terminals perform synchronous display based on the touch coordinates and the encoded synchronization image.
通过本申请实施例，服务器可以向各同步终端广播编码同步图像，以使得各同步终端接收到相同的显示画面图像并进行显示。当进行同步显示时，目标终端可以根据接收的控制指令确定触控坐标，并将该触控坐标发送至服务器，进而，当服务器接收到目标终端发送的触控坐标后，服务器可以基于触控坐标和编码同步图像执行同步操作，以实现各同步终端的同步显示。在此过程中，由于各同步终端的同步显示是基于触控坐标和编码同步图像实现的，而且各同步终端显示的编码同步图像又是相同的图像，因此，即使各同步终端之间存在显示屏尺寸不同、操作系统不同、应用程序版本不同等因素，也不会影响基于触控坐标和编码同步图像执行的同步操作，保证了屏幕共享时各个同步终端均可以正常显示相同的画面。Through the embodiment of the present application, the server can broadcast the encoded synchronization image to each synchronization terminal, so that each synchronization terminal receives and displays the same display screen image. When performing synchronous display, the target terminal can determine the touch coordinates according to the received control instructions, and send the touch coordinates to the server. Further, after the server receives the touch coordinates sent by the target terminal, the server can determine the touch coordinates based on the touch coordinates. Perform synchronous operation with the coded synchronous image to realize synchronous display of each synchronous terminal. In this process, since the synchronous display of each synchronous terminal is realized based on the touch coordinates and the coded synchronous image, and the coded synchronous image displayed by each synchronous terminal is the same image, even if there is a display screen between each synchronous terminal Factors such as different sizes, different operating systems, and different application versions will not affect the synchronization operations performed based on touch coordinates and coded synchronization images, ensuring that each synchronization terminal can display the same screen normally during screen sharing.
针对应用于上述同步显示系统的同步显示方法，如图2所示，图2为本申请实施例同步显示方法的流程图，具体的，该方法可以包括如下步骤：For the synchronous display method applied to the above-mentioned synchronous display system, as shown in FIG. 2, FIG. 2 is a flowchart of the synchronous display method according to an embodiment of the present application. Specifically, the method may include the following steps:
在步骤21，服务器向各同步终端广播编码同步图像，相应的，各同步终端接收服务器广播的编码同步图像。In step 21, the server broadcasts the encoded synchronization image to each synchronization terminal, and accordingly, each synchronization terminal receives the encoded synchronization image broadcast by the server.
各同步终端接收到编码同步图像之后，可以在显示装置(例如自身的显示屏、外接的显示屏等)中显示该编码同步图像。其中，由于各同步终端中显示的编码同步图像是服务器统一下发的，因此，各同步终端所显示的界面图像相同。After receiving the encoded synchronization image, each synchronization terminal may display the encoded synchronization image on a display device (eg, its own display screen, an external display screen, etc.). Wherein, since the coded synchronization images displayed in each synchronization terminal are uniformly distributed by the server, the interface images displayed by each synchronization terminal are the same.
另外，编码同步图像还包括对应的坐标系，当目标终端接收到用户通过外接设备(例如鼠标、键盘等)或者点触操作(例如用户通过触摸显示屏、通过触控笔点击显示屏等)输入的控制指令后，可以确定控制指令对应的触控坐标，而该触控坐标即为编码同步图像对应坐标系中的坐标。In addition, the coded synchronous image also includes a corresponding coordinate system. When the target terminal receives the input from the user through an external device (such as a mouse, keyboard, etc.) or a touch operation (such as the user touches the display screen, clicks the display screen with a stylus, etc.) After the control command is generated, the touch coordinates corresponding to the control command can be determined, and the touch coordinates are the coordinates in the coordinate system corresponding to the coded synchronization image.
在步骤22，各同步终端中的目标终端根据接收的控制指令确定触控坐标。In step 22, the target terminal in each synchronization terminal determines the touch coordinates according to the received control instruction.
其中，触控坐标可以用于表征用户操作的位置与编码同步图像之间的相对位置，即用户操作的位置在编码同步图像中的位置。The touch coordinates may be used to represent the relative position between the position of the user operation and the encoded synchronization image, that is, the position of the user operated position in the encoded synchronization image.
例如，如图3所示，图3为本申请实施例编码同步图像的示意图，其中，该示意图包括：编码同步图像30、触控坐标31、触控坐标32、触控坐标33、触控坐标34、提供给用户进行选择的工具栏35、提供给用户进行选择的选择按钮36以及提供给用户进行其它操作(例如书写、绘画等)的空白区域。For example, as shown in FIG. 3 , FIG. 3 is a schematic diagram of an encoded synchronous image according to an embodiment of the present application, wherein the schematic diagram includes: an encoded
其中，编码同步图像30是在各同步终端的显示装置中所显示的画面。当编码同步图像30是目标终端显示的画面时，用户可以通过触控笔、触控板、手指、鼠标、键盘或其他方式来触控显示屏中的工具栏35、选择按钮36或者空白区域，以实现输入控制指令的目的。Here, the coded
当目标终端接收到用户输入的控制指令后，目标终端可以根据接收的控制指令确定触控坐标。After the target terminal receives the control instruction input by the user, the target terminal can determine the touch coordinates according to the received control instruction.
例如，如图3所示，当用户输入控制指令以实现在空白区域书写“人”字时，目标终端可以根据用户输入的控制指令(即用户在空白区域书写“人”字时所划过的路径)确定用户在操作过程中对应的各触控坐标31(a，b)、触控坐标32(c，d)、触控坐标33(e，f)、触控坐标34(g，h)。For example, as shown in FIG. 3 , when the user inputs a control instruction to write the character "person" in the blank area, the target terminal can write the character "person" in the blank area according to the control instruction input by the user (that is, the line drawn by the user when writing the character "person" in the blank area path) to determine the touch coordinates 31 (a, b), touch coordinates 32 (c, d), touch coordinates 33 (e, f), and touch coordinates 34 (g, h) corresponding to the user during the operation .
需要说明的，图3仅示例性的列出4个触控坐标以说明本申请实施例中触控坐标的含义，实际上，用户在空白区域书写“人”字时，除了笔画起始点和终止点之外，目标终端还会确定书写过程中其它若干触控坐标。通过这些触控坐标以及预设的渲染方式，目标终端可以在空白区域显示用户所书写的“人”字。It should be noted that, FIG. 3 only exemplarily lists four touch coordinates to illustrate the meaning of the touch coordinates in the embodiment of the present application. In addition to the point, the target terminal will also determine several other touch coordinates during the writing process. Through these touch coordinates and a preset rendering method, the target terminal can display the character "person" written by the user in the blank area.
还需要说明的，在一种情况下，若用户输入的控制指令是带有执行顺序的(例如在书写时，用户需要按照先后顺序依次画出笔画)，则目标终端在确定触控坐标的同时，还需要确定各触控坐标的执行顺序。其中，各触控坐标的执行顺序可以根据目标终端接收控制指令的顺序确定，即先接收到的控制指令对应触控坐标的执行顺序在先，后接收到的控制指令对应触控坐标的执行顺序在后。例如，如图3所示，若用户在书写“人”字时，先从触控坐标31开始按照图3所示的方向书写至触控坐标32，再从触控坐标33开始按照图3所示的方向书写至触控坐标34已完成书写，那么，图3所示的4个触控坐标的执行顺序从先到后分别为：触控坐标31、触控坐标32、触控坐标33、触控坐标34。It should also be noted that, in one case, if the control command input by the user has an execution order (for example, when writing, the user needs to draw strokes in sequence), the target terminal determines the touch coordinates while determining the touch coordinates. , and also need to determine the execution order of each touch coordinate. The execution order of each touch coordinate can be determined according to the order in which the target terminal receives the control instructions, that is, the execution order of the first received control instruction corresponding to the touch coordinate comes first, and the later received control instruction corresponds to the execution order of the touch coordinate is behind. For example, as shown in FIG. 3 , if the user is writing the word “人”, he first starts from the touch coordinate 31 and writes to the touch coordinate 32 in the direction shown in FIG. 3 , and then starts from the touch coordinate 33 according to the direction shown in FIG. 3 . After writing in the direction shown to the touch coordinates 34, the execution order of the four touch coordinates shown in FIG. 3 is from first to last: touch coordinates 31, touch coordinates 32, touch coordinates 33, Touch coordinates 34.
在另一种情况下，若用户输入的控制指令是不带有执行顺序的(例如在绘画时，用户可以通过填充选项对一定区域进行填充)，则目标终端在确定触控坐标后无需确定各触控坐标的执行顺序。也就是说，若各触控坐标是同时目标终端同时确定的，则目标终端无需确定各触控坐标的执行顺序。In another case, if the control instructions input by the user do not have an execution order (for example, when drawing, the user can fill a certain area through the fill option), the target terminal does not need to determine each touch coordinate after determining the touch coordinates. The execution order of touch coordinates. That is, if each touch coordinate is determined by the target terminal at the same time, the target terminal does not need to determine the execution order of each touch coordinate.
在另一种情况下，若用户输入的控制指令是既带有执行顺序又不带有执行顺序的(例如在绘画时，用户可以先按照一定顺序绘制图形，然后再通过填充选项对图形进行填充)，则目标终端在确定触控坐标的同时，还需要确定各触控坐标的执行顺序，而且，同一执行顺序下可能存在多个触控坐标(例如对图形进行填充时确定的触控坐标)。In another case, if the control command input by the user has both execution order and no execution order (for example, when drawing, the user can first draw graphics in a certain order, and then fill the graphics through the fill option) ), when the target terminal determines the touch coordinates, it also needs to determine the execution order of each touch coordinate, and there may be multiple touch coordinates in the same execution order (for example, the touch coordinates determined when filling the graphics) .
在步骤23，目标终端向服务器发送触控坐标，相应的，服务器接收目标终端发送的触控坐标。In step 23, the target terminal sends the touch coordinates to the server, and correspondingly, the server receives the touch coordinates sent by the target terminal.
在步骤24，目标终端执行控制指令。In step 24, the target terminal executes the control instruction.
需要说明的，本申请实施例对步骤23和步骤24的执行顺序不进行限定，也就是说，本申请实施例既可以先执行步骤23再执行步骤24，也可以先执行步骤24再执行步骤23，还可以同时执行步骤23和骤24。It should be noted that the embodiment of the present application does not limit the execution order of step 23 and step 24, that is to say, the embodiment of the present application can either execute step 23 first and then execute step 24, or execute step 24 first and then execute step 23 , and step 23 and step 24 may also be performed at the same time.
在一种可选的实施方式中，步骤23可以执行为：目标终端向服务器发送操作请求，服务器响应于操作请求，向目标终端返回操作响应，目标终端响应于操作相应，向服务器发送触控坐标。In an optional implementation manner, step 23 may be performed as follows: the target terminal sends an operation request to the server, the server responds to the operation request and returns an operation response to the target terminal, and the target terminal responds to the operation and sends touch coordinates to the server .
其中，操作响应用于表征目标终端获取操作权限。The operation response is used to represent that the target terminal obtains the operation authority.
在本申请实施例中，在目标终端向服务器发送触控坐标之前，需要先向服务器获取相应的操作权限。也就是说，在各同步终端中，只有获取到操作权限的终端可以作为目标终端向服务器发送触控坐标，以实现同步显示的目的。这样，可以使得服务器在执行同步操作时，只接收目标终端发送的触控坐标，避免了其它同步终端的干扰，提高了同步过程的稳定性。In this embodiment of the present application, before the target terminal sends the touch coordinates to the server, it needs to obtain the corresponding operation authority from the server. That is to say, in each synchronous terminal, only the terminal that has obtained the operation authority can send the touch coordinates to the server as the target terminal, so as to realize the purpose of synchronous display. In this way, the server can only receive the touch coordinates sent by the target terminal when performing the synchronization operation, thereby avoiding the interference of other synchronization terminals and improving the stability of the synchronization process.
在一种可选的实施方式中，若服务器接收到同步终端中除目标终端以外的同步终端发送的操作请求，则本申请实施例可以执行：服务器响应于接收到各同步终端中除目标终端以外的同步终端发送的操作请求，向发送操作请求的同步终端返回拒绝响应，同步终端响应于接收到服务器返回的拒绝响应，接收服务器发送的触控坐标，并基于触控坐标和编码同步图像进行同步显示。In an optional implementation manner, if the server receives an operation request sent by a synchronization terminal other than the target terminal among the synchronization terminals, this embodiment of the present application may execute: the server responds to receiving an operation request among the synchronization terminals other than the target terminal In response to the operation request sent by the synchronization terminal, the synchronization terminal returns a rejection response to the synchronization terminal that sent the operation request. In response to receiving the rejection response returned by the server, the synchronization terminal receives the touch coordinates sent by the server, and synchronizes based on the touch coordinates and the encoded synchronization image. show.
例如，如图4所示，图4为本申请实施例服务器进行权限分发的流程图，具体包括如下步骤：For example, as shown in FIG. 4 , FIG. 4 is a flow chart of rights distribution performed by a server according to an embodiment of the present application, which specifically includes the following steps:
在步骤41，服务器向各同步终端广播编码同步图像，相应的，各同步终端接收服务器广播的编码同步图像。In step 41, the server broadcasts the encoded synchronization image to each synchronization terminal, and correspondingly, each synchronization terminal receives the encoded synchronization image broadcast by the server.
在步骤42，同步终端中的目标终端向服务器发送操作请求，相应的，服务器接收目标终端发送的操作请求。In step 42, the target terminal in the synchronization terminal sends an operation request to the server, and correspondingly, the server receives the operation request sent by the target terminal.
在步骤43，服务器向目标终端返回操作响应，相应的，目标终端接收服务器返回的操作响应。In step 43, the server returns an operation response to the target terminal, and accordingly, the target terminal receives the operation response returned by the server.
其中，当目标终端接收到服务器发送的操作响应后，即表征目标终端获取到了相应的操作权限，进而，目标终端可以在相应的权限内执行相应的操作。Wherein, when the target terminal receives the operation response sent by the server, it means that the target terminal has obtained the corresponding operation authority, and further, the target terminal can perform the corresponding operation within the corresponding authority.
在步骤44，同步终端中除目标终端以外的同步终端向服务器发送操作请求，相应的，服务器接收同步终端发送的操作请求。In step 44, the synchronization terminals other than the target terminal among the synchronization terminals send an operation request to the server, and correspondingly, the server receives the operation request sent by the synchronization terminal.
在步骤45，服务器向对应的同步终端返回拒绝响应，相应的，该同步终端接收服务器返回的拒绝响应。In step 45, the server returns a rejection response to the corresponding synchronization terminal, and correspondingly, the synchronization terminal receives the rejection response returned by the server.
也就是说，当各同步终端中存在已经获取到权限的终端(即目标终端)时，若其它的同步终端向服务器发送操作请求以获取操作权限，则服务器会拒绝该同步终端并返回拒绝响应。这样，可以使得服务器在执行同步操作时，只接收目标终端发送的触控坐标，避免了其它同步终端的干扰，提高了同步过程的稳定性。That is to say, when there is a terminal (ie, target terminal) that has obtained permission in each synchronization terminal, if other synchronization terminals send operation requests to the server to obtain operation rights, the server will reject the synchronization terminal and return a rejection response. In this way, the server can only receive the touch coordinates sent by the target terminal when performing the synchronization operation, thereby avoiding the interference of other synchronization terminals and improving the stability of the synchronization process.
在步骤25，服务器执行同步操作，以使得各同步终端中除目标终端以外的同步终端进行同步显示。In step 25, the server performs a synchronization operation, so that the synchronization terminals other than the target terminal among the synchronization terminals perform synchronization display.
其中，服务器在执行同步操作时，可以基于触控坐标和编码同步图像使得各同步终端中除目标终端以外的同步终端进行同步显示。例如，服务器可以将触控坐标所对应的操作还原至编码同步图像，并将还原操作后的编码同步图像发送至各同步终端，以使得各同步终端中除目标终端以外的同步终端进行同步显示。再例如，服务器也可以将触控坐标发送至各同步终端，以使得各同步终端中除目标终端以外的同步终端基于触控坐标和编码同步图像进行同步显示。Wherein, when the server performs the synchronization operation, the synchronization terminal other than the target terminal among the synchronization terminals can be displayed synchronously based on the touch coordinates and the encoded synchronization image. For example, the server can restore the operation corresponding to the touch coordinates to the coded synchronous image, and send the coded synchronous image after the restoration operation to each synchronous terminal, so that the synchronous terminals other than the target terminal among the synchronous terminals can display synchronously. For another example, the server may also send the touch coordinates to each synchronization terminal, so that the synchronization terminals other than the target terminal among the synchronization terminals perform synchronous display based on the touch coordinates and the encoded synchronization image.
例如，如图5所示，图5为本申请实施例同步显示过程的流程性示意图，其中，该示意图包括服务器511、同步终端中的目标终端512和其它同步终端513。For example, as shown in FIG. 5 , FIG. 5 is a schematic flowchart of a synchronization display process according to an embodiment of the present application, wherein the schematic diagram includes a
在步骤521，当目标终端512获取到相应的操作权限后，目标终端512可以根据控制指令确定触控坐标，然后向服务器511发送该触控坐标。In step 521 , after the
其中，触控坐标可以是单个坐标，也可以是多个触控坐标的集合。若目标终端512发送的是多个触控坐标的集合，则该集合中的多个触控坐标可以带有执行顺序，也可以不带有执行顺序。The touch coordinates may be a single coordinate, or may be a collection of multiple touch coordinates. If the
在步骤522，当服务器511接收到目标终端512发送的触控坐标后，服务器511可以根据该触控坐标执行同步操作，以使得各同步终端513与目标终端512同步显示。In step 522 , after the
其中，服务器511可以将触控坐标所对应的操作还原至编码同步图像，并将还原操作后的编码同步图像发送至各同步终端513。服务器511也可以将触控坐标发送至各同步终端513，以使得各同步终端513基于触控坐标和编码同步图像进行同步显示。The
如图5所示，目标终端512的空白区域中显示了“人”字，同步终端513在同步显示之前空白区域中没有内容，同步终端513在同步显示之后的空白区域中显示了“人”字。也就是说，通过本申请实施例，服务器可以向各同步终端广播编码同步图像，以使得各同步终端接收到相同的显示画面图像并进行显示。当进行同步显示时，目标终端可以根据接收的控制指令确定触控坐标，并将该触控坐标发送至服务器，进而，当服务器接收到目标终端发送的触控坐标后，服务器可以基于触控坐标和编码同步图像执行同步操作，以实现各同步终端的同步显示。在此过程中，由于各同步终端的同步显示是基于触控坐标和编码同步图像实现的，而且各同步终端显示的编码同步图像又是相同的图像，因此，即使各同步终端之间存在显示屏尺寸不同、操作系统不同、应用程序版本不同等因素，也不会影响基于触控坐标和编码同步图像执行的同步操作，保证了屏幕共享时各个同步终端均可以正常显示相同的画面。As shown in FIG. 5 , the word "person" is displayed in the blank area of the
在一种可选的实施方式中，上述步骤25具体可以执行为：服务器向各同步终端中除目标终端以外的同步终端发送触控坐标，同步终端接收到触控坐标后，解析触控坐标并与目标终端进行同步显示。In an optional implementation manner, the above step 25 may be specifically performed as follows: the server sends touch coordinates to the synchronization terminals other than the target terminal among the synchronization terminals, and after the synchronization terminal receives the touch coordinates, parses the touch coordinates and generates Synchronized display with the target terminal.
在此情况下，服务器在接收到目标终端发送的触控坐标后，可以直接将该触控坐标发送给各同步终端，这样，当服务器需要处理大量数据时，通过本申请实施例可以减轻运算压力，提高处理效率。In this case, after receiving the touch coordinates sent by the target terminal, the server can directly send the touch coordinates to each synchronous terminal. In this way, when the server needs to process a large amount of data, the embodiment of the present application can reduce the computational pressure , improve processing efficiency.
相应的，同步终端解析触控坐标后，由于触控坐标是表征用户操作的位置与编码同步图像之间的相对位置，即用户操作的位置在编码同步图像中的位置。因此，同步终端通过触控坐标可以准确确定对应操作在编码同步图像中的位置，保证了屏幕共享时各个同步终端均可以正常显示相同的画面。Correspondingly, after the synchronization terminal parses the touch coordinates, since the touch coordinates represent the relative position between the position of the user's operation and the encoded synchronization image, that is, the position of the user's operation in the encoded synchronization image. Therefore, the synchronization terminal can accurately determine the position of the corresponding operation in the encoded synchronization image through the touch coordinates, which ensures that each synchronization terminal can normally display the same picture when the screen is shared.
在一种可选的实施方式中，同步终端可以包括高优先级终端和低优先级终端，目标终端为高优先级终端。In an optional implementation manner, the synchronization terminals may include high-priority terminals and low-priority terminals, and the target terminal is a high-priority terminal.
具体的，上述步骤25具体可以执行为：服务器响应于触控坐标对应目标低优先级终端的选择控件，向各同步终端中除目标终端以外的同步终端发送触控坐标，同步终端接收到触控坐标后，解析触控坐标并与目标终端进行同步显示，服务器将目标终端的全部或部分操作权限转移至目标低优先级终端。Specifically, the above step 25 can be specifically executed as follows: the server, in response to the selection control of the touch coordinates corresponding to the target low-priority terminal, sends the touch coordinates to the synchronous terminals other than the target terminal among the synchronous terminals, and the synchronous terminal receives the touch After the coordinates are obtained, the touch coordinates are parsed and displayed synchronously with the target terminal, and the server transfers all or part of the operation authority of the target terminal to the target low-priority terminal.
也就是说，在目标终端为高优先级终端时，使用目标终端的用户可以选择任意目标低优先级终端，并将自身的全部或部分权限转移至该目标低优先级终端。That is, when the target terminal is a high-priority terminal, the user using the target terminal can select any target low-priority terminal, and transfer all or part of his own authority to the target low-priority terminal.
例如，在会议场景下，目标终端(高优先级终端)可以是会议主持人，其它同步终端可以是会议参与者。以图3为例，图3中的编码同步图像30是目标终端显示的画面，其中的各选择按钮36可以分别对应不同的同步终端。当会议主持人通过目标终端点击某一选择按钮36(例如选择按钮A)时，目标终端可以将对应的触控坐标发送给服务器，以使得服务器进行同步操作的同时，将目标终端的全部或部分权限转移给该选择按钮36对应的同步终端。For example, in a conference scenario, the target terminal (high-priority terminal) may be the conference host, and other synchronous terminals may be conference participants. Taking FIG. 3 as an example, the
然后，当该选择按钮36对应的同步终端获取到相应的操作权限后，使用该同步终端的会议参与者可以向该同步终端输入控制指令，以使得该同步终端将控制指令对应的触控坐标发送至服务器，进而使得服务器执行同步操作。Then, after the synchronization terminal corresponding to the
在本申请实施例中，通过设置同步终端的优先级，可以使得权限的控制更加规范化，扩大了系统的适用性。In the embodiment of the present application, by setting the priority of the synchronization terminal, the control of the authority can be more standardized, and the applicability of the system can be expanded.
在另一种可选的实施方式中，同步终端可以包括高优先级终端和低优先级终端，目标终端为低优先级终端。In another optional implementation manner, the synchronization terminals may include high-priority terminals and low-priority terminals, and the target terminal is a low-priority terminal.
具体的，上述步骤25具体可以执行为：服务器响应于触控坐标对应结束操作的选择控件，向各同步终端中除目标终端以外的同步终端发送触控坐标，同步终端接收到触控坐标后，解析触控坐标并与目标终端进行同步显示，服务器将目标终端的全部或部分操作权限转移至高优先级终端。Specifically, the above step 25 can be specifically executed as follows: the server sends the touch coordinates to the synchronization terminals other than the target terminal among the synchronization terminals in response to the selection control corresponding to the end operation corresponding to the touch coordinates, and after the synchronization terminal receives the touch coordinates, The touch coordinates are parsed and displayed synchronously with the target terminal, and the server transfers all or part of the operation authority of the target terminal to the high-priority terminal.
例如，在教学场景下，目标终端(低优先级终端)可以是课堂中的学生，其它同步终端包括其他学生(低优先级终端)以及课堂的老师(高优先级终端)。以图3为例，图3中的编码同步图像30是目标终端显示的画面，其中的选择按钮E可以是结束操作的选择控件。For example, in a teaching scenario, the target terminal (low-priority terminal) may be a student in the classroom, and other synchronous terminals include other students (low-priority terminal) and the teacher of the classroom (high-priority terminal). Taking FIG. 3 as an example, the
当学生通过目标终端点击选择按钮E时，目标终端可以将对应的触控坐标发送给服务器，以使得服务器进行同步操作的同时，将目标终端的全部或部分权限转移给老师对应的高优先级终端。When the student clicks the selection button E through the target terminal, the target terminal can send the corresponding touch coordinates to the server, so that the server can transfer all or part of the authority of the target terminal to the high-priority terminal corresponding to the teacher while the server performs the synchronous operation. .
进一步的，在一种可选的实施方式中，高优先级终端还可以主动收回权限，具体的，该过程具体可以执行为：服务器响应于接收到高优先级终端的权限收回指令，将目标终端的全部或部分操作权限转移至高优先级终端。Further, in an optional implementation manner, the high-priority terminal can also take the initiative to revoke the authority. Specifically, the process can be specifically performed as follows: the server responds to receiving the authority revocation instruction of the high-priority terminal, and reclaims the target terminal. All or part of the operation rights are transferred to the high-priority terminal.
例如，在教学场景下，目标终端(低优先级终端)可以是课堂中的学生，其它同步终端包括其他学生(低优先级终端)以及课堂的老师(高优先级终端)。以图3为例，图3中的编码同步图像30是老师所使用的同步终端显示的画面，其中的选择按钮E可以是用于发送权限收回指令的选择控件。For example, in a teaching scenario, the target terminal (low-priority terminal) may be a student in the classroom, and other synchronous terminals include other students (low-priority terminal) and the teacher of the classroom (high-priority terminal). Taking FIG. 3 as an example, the coded
当老师通过高优先级终端点击选择按钮E时，该高优先级终端可以将对应的触控坐标发送给服务器，以使得服务器进行同步操作的同时，将目标终端的全部或部分权限转移给老师对应的高优先级终端，即实现了权限收回操作。When the teacher clicks the selection button E through the high-priority terminal, the high-priority terminal can send the corresponding touch coordinates to the server, so that the server can transfer all or part of the authority of the target terminal to the corresponding teacher while performing the synchronous operation. The high-priority terminal implements the permission revocation operation.
在本申请实施例中，通过设置同步终端的优先级，可以使得权限的控制更加规范化，扩大了系统的适用性。In the embodiment of the present application, by setting the priority of the synchronization terminal, the control of the authority can be more standardized, and the applicability of the system can be expanded.

通过本申请实施例，服务器可以向各同步终端广播编码同步图像，以使得各同步终端接收到相同的显示画面图像并进行显示。当进行同步显示时，目标终端可以根据接收的控制指令确定触控坐标，并将该触控坐标发送至服务器，进而，当服务器接收到目标终端发送的触控坐标后，服务器可以基于触控坐标和编码同步图像执行同步操作，以实现各同步终端的同步显示。在此过程中，由于各同步终端的同步显示是基于触控坐标和编码同步图像实现的，而且各同步终端显示的编码同步图像又是相同的图像，因此，即使各同步终端之间存在显示屏尺寸不同、操作系统不同、应用程序版本不同等因素，也不会影响基于触控坐标和编码同步图像执行的同步操作，保证了屏幕共享时各个同步终端均可以正常显示相同的画面。Through the embodiment of the present application, the server can broadcast the encoded synchronization image to each synchronization terminal, so that each synchronization terminal receives and displays the same display screen image. When performing synchronous display, the target terminal can determine the touch coordinates according to the received control instructions, and send the touch coordinates to the server. Further, after the server receives the touch coordinates sent by the target terminal, the server can determine the touch coordinates based on the touch coordinates. Perform synchronous operation with the coded synchronous image to realize synchronous display of each synchronous terminal. In this process, since the synchronous display of each synchronous terminal is realized based on the touch coordinates and the coded synchronous image, and the coded synchronous image displayed by each synchronous terminal is the same image, even if there is a display screen between each synchronous terminal Factors such as different sizes, different operating systems, and different application versions will not affect the synchronization operations performed based on touch coordinates and coded synchronization images, ensuring that each synchronization terminal can display the same screen normally during screen sharing.
