Please refer to FIG. 1, which shows a flowchart of an embodiment of the screen projection method provided in the first aspect of the present application. As shown in FIG. 1, the screen projection method S100 includes:

S101、响应于投屏控制事件，确定投屏控制事件对应的投屏发送端。S101. In response to a screen projection control event, determine a screen projection sender corresponding to the screen projection control event.

该步骤中，投屏接收端可以与一个或多个投屏发送端连接，并接收每个投屏发送端发送的投屏资源，当检测到投屏控制事件发生时，可以根据投屏事件和当前接入的投屏发送端，确定该投屏事件对应的投屏发送端。In this step, the projection receiver can connect to one or more projection transmitters, and receive the projection resources sent by each projection transmitter. When a projection control event is detected, it can be based on the projection event and The currently connected screencasting sender determines the screencasting sender corresponding to the screencast event.

在一种可能的实施方式中，投屏控制事件可以包括以下至少一种：In a possible implementation manner, the screen projection control event may include at least one of the following:

当投屏控制事件为投屏发送端发送的投屏加入请求时，可以将当前已经与投屏接收端建立投屏连接的投屏发送端，及发送投屏加入请求的投屏发送端一同作为投屏控制事件对应的投屏发送端；当投屏控制事件为投屏退出请求时，可以将投屏接收端与发送投屏退出请求的投屏发送端的连接断开，并将发送投屏退出请求的投屏发送端对应的投屏窗口关闭，再确定当前已与投屏接收端建立投屏连接的投屏发送端为投屏控制事件对应的投屏发送端；当投屏控制事件为投屏设备删除指令时，可以将投屏接收端与投屏设备删除指令指示的投屏发送端之间的投屏连接断开，并确定断开后与投屏接收端建立投屏连接的投屏发送端为投屏控制事件对应的投屏发送端。When the projection control event is a projection join request sent by the projection sender, the projection sender that has established a projection connection with the projection receiver and the projection sender that sends the projection join request can be used as the same The projection sender corresponding to the projection control event; when the projection control event is a projection exit request, the connection between the projection receiver and the projection sender that sent the projection exit request can be disconnected, and the sending projection will exit The projection window corresponding to the requested projection sender is closed, and then the projection sender that has established a projection connection with the projection receiver is the projection sender corresponding to the projection control event; when the projection control event is the projection When the screen device delete instruction, you can disconnect the screen projection connection between the screen projection receiving end and the screen projection sending end indicated by the screen projection device deletion instruction, and confirm the disconnection and establish a screen projection connection with the projection receiving end The sender is the screencast sender corresponding to the screencast control event.

投屏方法S100还包括：The projection method S100 also includes:

S102、根据投屏发送端的数量，确定每个投屏发送端对应的投屏参数。S102: Determine a screen projection parameter corresponding to each screen projection sending terminal according to the number of screen projection sending terminals.

该步骤中，在确定投屏控制事件对应的投屏发送端的数量后，可以根据投屏发送端的数量，将投屏接收端的图形用户界面划分为多个显示区域，每个显示区域可以对应一个投屏发送端，并在该显示区域生成与投屏发送端对应的投屏窗口，每个投屏窗口的大小可以是相同的，也可以是不同的。在生成投屏窗口后，可以分别将每个投屏窗口的尺寸作为其对应的投屏参数。投屏窗口尺寸是能够表征投屏窗口大小、形状的具体数值。投屏发送端可以基于该投屏参数对其发送的投屏资源进行设置，以适应投屏窗口大小。投屏接收端在收到该投屏资源后可以直接显示在对应的投屏窗口中，避免投屏接收端对投屏资源进行压缩等处理，有效减少投屏接收端的计算资源占用，减少投屏画面出现卡顿、卡死等情况。In this step, after determining the number of projection sending ends corresponding to the projection control event, the graphical user interface of the projection receiving end can be divided into multiple display areas according to the number of projection sending ends, and each display area can correspond to one projection. Screen sender, and generate a screen projection window corresponding to the screen projection sender in the display area, and the size of each screen projection window can be the same or different. After the projection window is generated, the size of each projection window can be used as its corresponding projection parameter. The size of the projection window is a specific value that can characterize the size and shape of the projection window. The projection sender can set the projection resources it sends based on the projection parameters to adapt to the size of the projection window. After receiving the projection resource, the projection receiving terminal can directly display it in the corresponding projection window, avoiding the projection receiving terminal from compressing the projection resources, and effectively reducing the computing resource occupation of the projection receiving terminal and reducing the projection. Stuttering, freezing, etc. appear on the screen.

投屏方法S100还包括：The projection method S100 also includes:

S103、将投屏参数发送至其对应的投屏发送端，以使投屏发送端根据投屏参数，发送投屏资源至投屏接收端。S103: Send the screen projection parameter to its corresponding screen projection sending end, so that the screen projection sending end sends the screen projection resource to the screen projection receiving end according to the screen projection parameter.

该步骤中，在投屏接收端将投屏参数发送至各个投屏发送端后，投屏接收端可以根据接收到的投屏参数，确定推送投屏资源的分辨率和码率，并按照确定的分辨率及码率将投屏资源发送至投屏接收端。示例性的，可以根据投屏参数与分辨率和码率的映射关系，确定投屏资源的分辨率和码率。In this step, after the projection receiver sends the projection parameters to each projection sender, the projection receiver can determine the resolution and code rate of the projection resource to be pushed according to the received projection parameters, and follow the determination The resolution and bit rate will send the projection resource to the projection receiver. Exemplarily, the resolution and code rate of the projection resource can be determined according to the mapping relationship between the projection parameters and the resolution and code rate.

对于已经和投屏接收端建立投屏连接的投屏发送端，可以将原有的投屏资源的发送中断，并以新接收到的投屏参数对应的分辨率和码率重新采集投屏资源，并发送至投屏接收端；对于原来未与投屏接收端建立投屏连接，新加入的投屏发送端，则直接以接收到的投屏参数对应的分辨率和码率重新采集投屏资源，并发送至投屏接收端。For the projection sender that has established a projection connection with the projection receiver, the transmission of the original projection resource can be interrupted, and the projection resource can be re-collected with the resolution and code rate corresponding to the newly received projection parameter , And send to the projection receiver; for the original projection connection that has not been established with the projection receiver, the newly added projection transmitter will directly re-collect the projection screen at the resolution and code rate corresponding to the received projection parameter Resources, and sent to the receiving end of the projection screen.

投屏方法S100还包括：The projection method S100 also includes:

S104、接收并展示每个投屏发送端发送的投屏资源。S104. Receive and display the screen projection resources sent by each screen projection sender.

这样，在投屏发送端的数量增加或减少时，投屏发送端可以根据新的投屏发送端的数量，确定每个投屏发送端的投屏参数，并使投屏发送端根据投屏参数传输投屏资源。In this way, when the number of projection sending terminals increases or decreases, the projection sending terminal can determine the projection parameters of each projection sending terminal according to the number of new projection sending terminals, and make the projection sending terminal transmit the projection according to the projection parameters. Screen resources.

由于投屏发送端接收到的投屏资源是与投屏窗口适配的投屏资源，因此，不需要在进行压缩等操作，能够将原来由投屏接收端进行的处理分散转移至投屏发送端，有效降低投屏接收端的运行资源占用，并减少因资源占用过高引起的投屏画面卡顿、卡死等问题。Since the projection resource received by the projection sender is a projection resource that is adapted to the projection window, there is no need to perform operations such as compression, and the processing originally performed by the projection receiver can be dispersed and transferred to the projection transmission It effectively reduces the operating resource occupancy of the projection receiving terminal, and reduces the problem of screen freezing and freezing caused by excessive resource occupancy.

请参阅图2，图2示出了本申请第一方面提供的投屏方法的另一个实施例的流程图。如图2中所示，投屏方法S200可以包括：Please refer to FIG. 2, which shows a flowchart of another embodiment of the screen projection method provided in the first aspect of the present application. As shown in FIG. 2, the screen projection method S200 may include:

针对每个投屏发送端，将该投屏发送端对应的投屏资源的投屏窗口尺寸发送至该投屏发送端，以使该投屏发送端根据投屏窗口尺寸确定投屏资源的分辨率及码率，并按照确定的分辨率及码率向投屏接收端发送投屏资源。For each projection sender, the projection window size of the projection resource corresponding to the projection sender is sent to the projection sender, so that the projection sender determines the resolution of the projection resource according to the projection window size Rate and bit rate, and send the screen resources to the screen receiving end according to the determined resolution and bit rate.

这样可优化投屏接收端的性能资源消耗，在多路投屏时投屏接收端的性能消耗不会成倍数的递增，这样可以保证投屏接收端流畅的运行，由于投屏发送端发送的投屏资源的分辨率和码率是根据投屏接收端给的尺寸而编码的，这样在投屏接收端就不需要压缩接收端的数据流尺寸，可以清晰的显示在投屏接收端的投屏窗口内。从而解决了投屏窗口在接收端的清晰度问题。This can optimize the performance and resource consumption of the projection receiving end, and the performance consumption of the projection receiving end will not increase by multiples during multi-channel projection.

This solves the problem of the clarity of the projection window at the receiving end.

由于发送的数据是进过优化后的数据，在传输过程中没有传输过多的不必要数据，从而节省了投屏发送端和投屏接收端的网络资源、中央处理器(Central Processing Unit，CPU)资源、内存资源，大大提高了软件的可用性。Since the data sent is optimized data, there is not too much unnecessary data transmitted during the transmission process, which saves the network resources and central processing unit (CPU) of the projection sender and the projection receiver. Resources and memory resources greatly improve the usability of the software.

其中，投屏加入请求及投屏退出请求可以是投屏发送端向投屏接收端发送的，也可以是用户在投屏接收端主动输入的指令；投屏设备删除指令可以是用户在投屏接收端主动输入的指令。Among them, the screen-casting join request and screen-casting exit request can be sent by the screen-casting sender to the screen-casting receiving end, or they can be instructions actively input by the user at the screen-casting receiving end; the screen-casting device deletion instruction can be the user's screen-casting Commands actively input by the receiving end.
