技术领域
本公开涉及计算机技术领域，具体而言，本公开涉及一种投屏方法、装置、电子设备及计算机可读介质。
背景技术
无线投屏又叫无线同屏、飞屏或屏幕共享。具体来说，就是将投屏源的画面实时地显示到投屏设备的屏幕上，其中，投屏源可以是手机、平板、笔记本、电脑等，投屏设备可以是平板、笔记本、电脑、电视、一体机、投影仪等，投屏设备的屏幕上显示的内容包括各类媒体信息、实时操作画面等。
相关技术中一个投屏设备与一个投屏源相互连接，该投屏设备开启一个窗口，该窗口用于显示该投屏源向该投屏设备投射的内容；当该投屏源与该投屏设备断开时，该窗口显示无投屏内容，即变成无画面窗口。目前的投屏方法对投屏窗口等资源的利用不够充分，造成了资源浪费，同时也降低了客户的体验度。现有的投屏技术中，投屏软件都只能简单的对投屏内容进行投屏，而对于投屏内容的参数调节和投屏管理，现有的投屏软件 都没有涉及。且在空间较大的范围内，不同视角的用户可能看不清投屏内容。本公开旨在解决上述问题之一。

本公开实施例中，确定第一连接数和第一窗口数，第一连接数是执行断开前与投屏设备连接的第一目标投屏源的个数，第一窗口数是投屏设备上已开启的目标窗口的个数。
本公开实施例中，目标窗口用于显示投屏源向投屏设备投射的投屏信息。
本公开实施例中，窗口用于显示投屏源向投屏设备投射的投屏信息。
本公开实施例中，获取开连接指令和开窗口指令，开连接指令用于指示投屏设备与投屏源进行连接，开窗口指令用于指示开启投屏设备上的窗口。
本公开实施例中，开窗口指令可以由用户终端在本地触发，用户终端发送开窗口指令给投屏设备，其中，示例性地，用户终端可以为投屏设备的应用程序，例如APP客户端，或者可以为用于控制投屏设备的远程控制终端；开连接指令是由投屏源触发，投屏源可以通过无线局域网Wi-Fi发送开连接指令给投屏设备。开窗口指令和开连接指令分别由用户终端和投屏源发送给投屏设备，可以避免由于用户终端同时发送开窗口指令和开连 接指令而导致的误连接，也可以避免由于投屏源同时发送开窗口指令和开连接指令而导致的误开窗口。
本公开实施例中，投屏设备的一个窗口上可以诸如切换地显示多个投屏源的标签，多个投屏源中的任一投屏源的标签所显示的状态可以包括熄灭、选中、点亮中的任意一项，标签所显示的状态可以用于指示投屏源与投屏设备的不同连接状态，例如熄灭表示未连接，选中表示将要连接，点亮表示已连接。
本公开实施例中，第一连接数大于等于2，第一窗口数大于等于1，第一连接数是执行断开前与投屏设备连接的第一目标投屏源的个数。
本公开实施例中，如图1所示，第一连接数为2，第一窗口数为1。投屏设备的唯一开启的窗口101的工具栏102上显示的三个投屏源的标签分别是设备103、设备104和设备105，将与投屏设备实现连接的每一投屏源定义为第一目标投屏源，将被开启的每一窗口定义为目标窗口。投屏源的标签可以用不同的显示样式指示投屏设备与投屏源之间的不同状态。投屏源的标签可以包括三个状态，这三个状态分别是熄灭、点亮和选中；其中，若投屏源的标签显示灰色，则表示熄灭，即投屏设备与投屏源处于断开状态，例如设备103；若投屏源的标签显示蓝色或白色，则表示点亮，即投屏设备与投屏源处于连接状态，例如设备104和设备105；选中表示用户点击投屏源的标签，即选择该投屏源向投屏设备投射投屏信息。
本公开实施例中提供了一种投屏方法，该方法的流程示意图如图2所示，该方法包括：
S101，获取断连接指令。
本公开实施例中，断连接指令用于指示断开至少一个第一目标投屏源与投屏设备的连接。在一实施例中，断连接指令可以由投屏源触发，投屏源发送断连接指令给投屏设备，在其他实施例中，断连接指令也可以由其他设备触发，本公开不做限定。
S102，根据断连接指令，断开至少一个第一目标投屏源与投屏设备的连接，并确定第二连接数，第二连接数是未断开的第一目标投屏源的个数。
本公开实施例中，一种可选的方式，投屏设备与N个第一目标投屏源 处于连接状态，当检测到M个第一目标投屏源与投屏设备断开连接，则确定未断开的第一目标投屏源的个数为N-M，即N与M之间求差；其中，N和M都为正整数，N大于M，第一连接数为N，第二连接数为N-M。
例如，投屏设备与3个第一目标投屏源处于连接状态，当检测到1个第一目标投屏源与投屏设备断开连接，则确定未断开的第一目标投屏源的个数为2，即3与2之间求差；其中，第一连接数为3，第二连接数为2。
本公开实施例中，另一种可选的方式，投屏设备根据断连接指令，断开S个第一目标投屏源与投屏设备的连接，投屏设备检测到K个未断开的第一目标投屏源，则确定第二连接数为K；其中，S和K都为正整数。
S103，根据第二连接数和第一窗口数，显示未断开的各个第一目标投屏源向投屏设备投射的投屏信息，第一窗口数是投屏设备上已开启的目标窗口的个数。
本公开实施例中，投屏信息包括各类媒体信息、实时操作画面等。

当第二连接数小于第一窗口数时，关闭第二窗口数的目标窗口，第二窗口数小于第一窗口数；利用未关闭的各个目标窗口，显示未断开的各个第一目标投屏源向投屏设备投射的投屏信息；
或，当第二连接数大于或等于第一窗口数时，保持第一窗口数的目标窗口处于开启状态；利用第一窗口数的目标窗口，显示未断开的各个第一目标投屏源向投屏设备投射的投屏信息。
本公开实施例中，第一窗口数可以等于或大于第一连接数，当第二连接数小于第一窗口数，可以通过关闭全部或部分冗余的目标窗口，使保留开启的目标窗口的个数与未断开的第一目标投屏源的个数相同、或者使保留开启的目标窗口的个数大于未断开的第一目标投屏源的个数，从而保证能够有适当数量的目标窗口用于显示未断开的第一目标投屏源的投屏信息。
本公开实施例中，若第二连接数小于第一窗口数，可以关闭第二窗口数的目标窗口，第二窗口数小于第一窗口数。若第二连接数为N-M、第一 窗口数为N，即第一窗口数等于第一连接数，可以确定未断开的第一目标投屏源的个数N-M小于投屏设备上已开启的目标窗口的个数N，以及冗余的目标窗口的个数为M，即第二窗口数为M；关闭M个冗余的目标窗口，保留N-M个已开启的目标窗口，这样，可以使保留开启的目标窗口的个数与未断开的第一目标投屏源的个数相同，即，均为N-M；或者，关闭部分冗余的目标窗口，即关闭F个冗余的目标窗口，保留N-F个已开启的目标窗口，未关闭的冗余的目标窗口的数量为M-F个；其中，N、M和F都为正整数，N大于M，M大于F。
本公开实施例中，若第二连接数小于第一窗口数，可以关闭第二窗口数的目标窗口，第二窗口数小于第一窗口数。若第二连接数为N-M、第一窗口数为H，当第一窗口数H大于第一连接数N，可以确定未断开的第一目标投屏源的个数N-M小于投屏设备上已开启的目标窗口的个数H，以及冗余的目标窗口的个数为H-N+M，即第二窗口数为H-N+M；关闭H-N+M个冗余的目标窗口，保留N-M个已开启的目标窗口，这样，可以使保留开启的目标窗口的个数与未断开的第一目标投屏源的个数相同，即，均为N-M。或者，关闭部分冗余的目标窗口，即关闭F个冗余的目标窗口，保留H-F个已开启的目标窗口，未关闭的冗余的目标窗口的数量为H-N+M-F个；其中，H、N、M和F都为正整数，N大于M，M大于F。
本公开实施例中，实现了当断开至少一个第一目标投屏源与投屏设备之间的连接时，如果未断开的第一目标投屏源的个数小于投屏设备上已开启的目标窗口的个数，就会相应的关闭一个或多个的目标窗口，节省了窗口资源，提升了用户体验。
本公开实施例中，断开至少一个第一目标投屏源与投屏设备的连接，包括：
断开一个第一目标投屏源与投屏设备的连接，其中，该第一目标投屏源在断开连接之前，在第一连接数的目标窗口上，显示该第一目标投屏源向投屏设备投射的投屏信息，第一连接数是执行断开前与投屏设备连接的第一目标投屏源的个数；
相应地，显示未断开的各个第一目标投屏源向投屏设备投射的投屏信息，包括：通过切换显示，来显示未断开的各个第一目标投屏源向投屏设备投射的投屏信息。
本公开实施例中，在断开一个第一目标投屏源与投屏设备的连接之后，还包括：
关闭最后开启的至少一个目标窗口。
本公开实施例中，举例说明，与投屏设备断开连接的第一目标投屏源为A投屏源，与投屏设备未断开的第一目标投屏源为B投屏源，投屏设备上已开启的每一窗口定义为目标窗口，第一连接数为2，第一窗口数为2或3，第二连接数为1。基于此，若A和B两个投屏源与投屏设备处于连接中，开启了2或3个窗口都显示A投屏源投射到投屏设备的画面，此时A投屏源主动或被动断开，则分别关闭1或2个最后开启的窗口，只保留1个窗口，自动切换至B投屏源投射到投屏设备的画面，即保留的1个窗口显示B投屏源的画面。
本公开实施例中，举例说明，与投屏设备断开连接的第一目标投屏源为A投屏源，与投屏设备未断开的第一目标投屏源为B和C投屏源，投屏设备上已开启的每一窗口定义为目标窗口，第一连接数为3，第一窗口数为3，第二连接数为2，第二窗口数为1。基于此，若A、B和C三个投屏源与投屏设备处于连接中，开启的3个窗口都显示A投屏源投射到投屏设备的画面，此时A投屏源主动或被动断开，则关闭1个最后开启的窗口，保留2个窗口，自动切换至B和C投屏源投射到投屏设备的画面，即保留的2个窗口分别显示B和C投屏源向投屏设备投射的投屏信息。
本公开实施例中，若第二连接数大于或等于第一窗口数，则保持第一窗口数的目标窗口处于开启状态；利用第一窗口数的目标窗口，显示未断开的各个第一目标投屏源向投屏设备投射的投屏信息。
本公开实施例中，举例说明，与投屏设备断开连接的第一目标投屏源为A投屏源，与投屏设备未断开的第一目标投屏源为B和C投屏源，投屏设备上已开启的每一窗口定义为目标窗口，第一连接数为3，第一窗口数为1，第二连接数为2。基于此，若A、B和C三个投屏源与投屏设备 处于连接中，只开启了1个窗口显示A投屏源投射到投屏设备的画面，此时A设备主动断开，则不关闭任何窗口，当前窗口自动切换至B或C投屏源投射到投屏设备的画面，被切换的投屏源可以是B和C投屏源中的任一个、或是B和C投屏源中最后一个连接投屏设备的投屏源。
本公开实施例中，利用第一窗口数的目标窗口，显示未断开的各个第一目标投屏源向投屏设备投射的投屏信息，包括：
利用第一窗口数的目标窗口，显示第三连接数的未断开的第一目标投屏源向投屏设备投射的投屏信息；
其中，第三连接数小于或等于第一窗口数，第三连接数的第一目标投屏源基于第一目标投屏源与投屏设备之间建立连接的时间顺序来确定。
本公开实施例中，利用第一窗口数的目标窗口，显示第三连接数的未断开的第一目标投屏源向投屏设备投射的投屏信息，包括：
利用第一窗口数的目标窗口，显示第三连接数的未断开的不同或相同的第一目标投屏源向投屏设备投射的投屏信息。
本公开实施例中，举例说明，与投屏设备断开连接的第一目标投屏源为A投屏源，与投屏设备未断开的第一目标投屏源为B和C投屏源，投屏设备上已开启的每一窗口定义为目标窗口，第一连接数为3，第一窗口数为2，第三连接数为2。基于此，若A、B和C三个投屏源与投屏设备处于连接中，只开启了2个窗口都显示A投屏源投射到投屏设备的画面，此时A投屏源主动或被动断开，则不关闭任何窗口，这2个窗口自动切换至B和C投屏源投射到投屏设备的画面，B和C投屏源为最后两个连接投屏设备的投屏源。或者，这2个窗口自动切换至B投屏源投射到投屏设备的画面，B投屏源为最后连接投屏设备的投屏源。或者，这2个窗口自动切换至C投屏源投射到投屏设备的画面，C投屏源为最后连接投屏设备的投屏源。
本公开实施例中，当检测到全部的目标窗口处于断开状态，断开与投屏设备处于连接状态的全部第一目标投屏源之间的连接。
本公开实施例中，若投屏设备上的所有窗口关闭，则断开所有第一目标投屏源与投屏设备之间的连接。例如，2-3个第一目标投屏源与投屏设 备处于连接中，投屏设备只开启了1个窗口，用户此时点击关闭键，关闭该窗口，该窗口关闭前弹出对话框：“关闭应用将断开所有连接，如需断开当前连接，请点击返回键。是否断开所有连接？确定/返回”。
本公开实施例中提供了另一种投屏方法，该方法的流程示意图如图3所示，该方法包括：
S201，获取第一开连接指令和开窗口指令，第一开连接指令用于指示投屏设备与投屏源进行连接，开窗口指令用于指示开启投屏设备上的窗口。
本公开实施例中，窗口用于显示投屏源向投屏设备投射的投屏信息。
本公开实施例中，如图4所示，开窗口指令可以由用户终端202触发，用户终端202发送开窗口指令给投屏设备201，其中，用户终端202可以为投屏设备201的应用程序APP客户端；开连接指令可以由投屏源203触发，投屏源203可以通过无线局域网Wi-Fi发送开连接指令给投屏设备201。在实施例中，通过由用户终端发送开窗口指令来开启投屏设备的投屏服务，使得投屏源不会误操作投屏到投屏设备上，换言之，若投屏设备201没有开启投屏服务，投屏源203不会强制投屏，投屏源203会投不上去，例如，若用户终端202发送开窗口指令指示投屏设备201开启至少一个窗口，则投屏设备201在接收到开窗口指令之后，会开启投屏服务，此后，投屏源可以在该投屏设备201上进行投屏。
S202，接收窗口显示指令，利用各个目标窗口，显示各个第一目标投屏源向投屏设备投射的投屏信息；其中，各个目标窗口包括在开窗口指令指示开启的各个窗口中、窗口显示指令指示的窗口，各个第一目标投屏源包括开连接指令指示第一连接的投屏源。
本公开实施例中，窗口显示指令用于指示目标窗口上显示投屏源向投屏设备投射的投屏信息。例如，投屏设备同时与三个第一目标投屏源处于连接状态，同时开启投屏设备上的三个窗口，窗口显示指令指示这三个窗口上分别显示这三个第一目标投屏源向投屏设备投射的投屏信息。
本公开实施例中，确定第一连接数和第一窗口数，第一连接数是与投屏设备连接的第一目标投屏源的个数，第一窗口数是投屏设备上已开启的 目标窗口的个数；获取第二开连接指令，第二开连接指令用于指示投屏设备与第二目标投屏源进行连接；根据第一连接数和第一窗口数，显示第二目标投屏源向投屏设备投射的投屏信息；其中，第二目标投屏源是除各个第一目标投屏源之外的投屏源。
本公开实施例中，根据第一连接数和第一窗口数，显示第二目标投屏源向投屏设备投射的投屏信息，包括：
当第一连接数小于第一预设阈值、第一窗口数等于第二预设阈值，在显示同一个第一目标投屏源投射的投屏信息的两个目标窗口中的至少一个目标窗口中，显示第二目标投屏源向投屏设备投射的投屏信息；
或，当第一连接数等于第一预设阈值，根据获取的断连接指令，在各个目标窗口中的至少一个目标窗口中，显示第二目标投屏源向投屏设备投射的投屏信息，断连接指令用于指示断开各个第一目标投屏源中的至少一个第一目标投屏源。
本公开实施例中，当第一连接数小于第一预设阈值、第一窗口数等于第二预设阈值，在显示同一个第一目标投屏源投射的投屏信息的两个目标窗口中的至少一个目标窗口中，显示第二目标投屏源向投屏设备投射的投屏信息。举例说明，第一连接数为2，第一窗口数为3，第一预设阈值为3和第二预设阈值为3，投屏设备上已开启的每一窗口定义为目标窗口。窗口1显示1号投屏源向投屏设备投射的画面，窗口2显示1号投屏源向投屏设备投射的画面，窗口3显示2号投屏源向投屏设备投射的画面；3号投屏源为第二目标投屏源，若3号投屏源要和投屏设备连接，可以在窗口1或窗口2中选择一个窗口来显示3号投屏源向投屏设备投射的画面，例如，选择窗口1来显示3号投屏源向投屏设备投射的画面。
本公开实施例中，根据获取的断连接指令，在各个目标窗口中的至少一个目标窗口中，显示第二目标投屏源向投屏设备投射的投屏信息，包括：
根据获取的断连接指令，将目标窗口作为新连接进来的第二目标投屏源的显示窗口，通过显示窗口显示第二目标投屏源向投屏设备投射的投屏信息，其中，断连接指令指示断开第一目标投屏源与投屏设备之间的连接， 第一目标投屏源向投屏设备投射的投屏信息显示在显示窗口上。
举例说明，第一连接数为3，第一窗口数为3，第一预设阈值为3和第二预设阈值为3，投屏设备上已开启的每一窗口定义为目标窗口。基于此，1号投屏源、2号投屏源和3号投屏源为第一目标投屏源，4号投屏源为第二目标投屏源。窗口1上显示1号投屏源向投屏设备投射的画面，窗口2上显示2号投屏源向投屏设备投射的画面，窗口3上显示3号投屏源向投屏设备投射的画面。获取的断连接指令指示断开1号投屏源与投屏设备之间的连接，将窗口1作为新连接进来的4号投屏源的显示窗口，通过窗口1显示4号投屏源向投屏设备投射的投屏信息。
本公开实施例中，根据获取的断连接指令，在各个目标窗口中的至少一个目标窗口中，显示第二目标投屏源向投屏设备投射的投屏信息，包括：
根据获取的断连接指令，并通过各个目标窗口中有焦点的目标窗口、各个目标窗口的提示、预设的选择框中的至少一项，确定至少一个目标窗口；
在至少一个目标窗口中，显示第二目标投屏源向投屏设备投射的投屏信息。
举例说明，第一连接数为3，第一窗口数为3，第一预设阈值为3和第二预设阈值为3，投屏设备上已开启的每一窗口定义为目标窗口。基于此，1号投屏源、2号投屏源和3号投屏源为第一目标投屏源，4号投屏源为第二目标投屏源。窗口1上显示1号投屏源向投屏设备投射的画面，若有与投屏设备新连接的2号投屏源，则开启窗口2；若有与投屏设备新连接的3号投屏源，则开启窗口3。当4号投屏源要与投屏设备连接时，当前有焦点的窗口会弹出提示用户，例如，窗口2是当前有焦点的窗口，是否断开2号投屏源，连接4号投屏源；或者，弹出选择框，询问断开1号投屏源、2号投屏源和3号投屏源中哪一个以便连接4号投屏源；或者，无论是否有焦点的窗口都会弹出提示，提示用户点击断开1号投屏源、2号投屏源和3号投屏源中任意一个以便连接4号投屏源。
本公开实施例中，第一预设阈值用于表征投屏设备能够连接的投屏源 的最大数量，第二预设阈值用于表征投屏设备上能够开启的窗口的最大数量。其中，第一预设阈值和第二预设阈值为大于或等于1的整数。
本公开实施例中，举例说明，第一预设阈值为3，投屏设备能够连接的投屏源的最大数量为3；第二预设阈值为3，投屏设备上能够开启的窗口的最大数量为3。
本公开实施例中，当投屏设备没有开启投屏服务，投屏源不会强制投屏，投屏源会投不上去，避免了误投屏；从而节省了窗口资源，提升了用户体验。
本公开实施例中提供了又一种投屏方法，如图5所示，该方法包括：
步骤S501，接收投屏发射端发送的投屏内容，并在投屏接收端的投屏显示界面显示投屏内容；其中，投屏显示界面设置有显示状态调节区域；
步骤S502，接收用户基于显示状态调节区域的显示状态调节操作；
步骤S503，基于显示状态调节操作调节投屏显示界面的显示状态。
在本公开实施例中，投屏接收端是指用于展示投屏内容的终端，可以是液晶显示器、电子墨水屏、投影仪等显示装置，投屏发射端是指用于将投屏内容发送至投屏接收端的终端，可以是电脑、手机、平板电脑等电子设备，其中，投屏接收端和投屏发射端之间建立通信连接，可以是有线通信，也可以是无线通信，如图6所示，投屏接收端601与多个投屏发射端602之间建立通信连接，在投屏发射端与投屏接收端建立通信连接时，投屏发射端将投屏内容发送至投屏接收端，投屏接收端对投屏内容进行展示。
在本公开实施例中，为方便说明，以一个具体实施例为例，用户在通过电脑进行远程投屏时，一个投屏发射端为一台电脑，投屏接收端为具有通信功能的显示设备，如具有通信功能的投影仪，电脑端用户通过电脑向投影仪投屏视频，投影仪对该视频进行展示，在展示过程中，投屏接收端会接收投屏发射端发送的投屏内容，并在投屏接收端的投屏显示界面对该投屏内容进行展示，其中，如图7所示，投屏显示界面701中显示有投屏内容702以及状态调节区域703，并通过显示状态调节区域703接收用户的显示状态调节操作，并基于该显示状态调节操作调节该投屏显示界面的显示状态。可选的，该显示状态调节操作可以是用户直接在投屏接收端或 者投屏发射端进行的操作，也可以是通过手机、遥控器等移动控制端进行的操作，基于该显示状态调节操作，可以调节投屏显示界面的分辨率、显示界面开关状态以及显示界面的显示模式等。
本公开实施例通过在显示投屏内容的投屏显示界面设置显示状态调节区域，基于该显示状态调节区域接收用户的显示状态调节操作，并基于该显示状态调节操作调节投屏显示界面的显示状态，用户可以直接在投屏接收端或者通过遥控设备对投屏显示界面的显示状态进行调节，使用十分方便。
本公开提供了一种可能的实现方式，在该实现方式中，显示状态调节区域设置有分辨率调节区域，显示状态调节操作包括分辨率调节操作，基于显示状态调节操作调节投屏显示界面的显示状态，包括：
基于分辨率调节操作调节投屏显示界面的显示分辨率。
在本公开实施例中，投屏显示界面的状态显示区域设置有分辨率调节区域，用户可以基于该分辨率调节区域调节投屏显示界面的分辨率。
对于本公开实施例，为方便说明，以一个具体实施为例，如图8所示，投屏显示界面801中显示有投屏内容802，其中，在显示状态调节区域803中设置有分辨率调节区域804，通过该分辨率调节区域804接收用户的分辨率调节操作，其中，分辨率调节区域804可以是下拉式调节控件，用户通过鼠标点击等操作，触发分辨率调节区域显示可选分辨率，用户通过可以选择目标分辨率，投屏发射端基于该目标分辨率对投屏内容的分辨率进行调节，使投屏内容的分辨率为该目标分辨率。
本公开实施例通过在显示状态调节区域设置分辨率调节区域，并基于该分辨率调节区域接收用户的分辨率调节操作，并基于该分辨率调节操作调节投屏显示界面的分辨率，用户可以对投屏内容的分辨率随时进行调节，使用方便。
本公开实施例提供了一种可能的实现方式，在该实现方式中，如图9所示，基于分辨率调节操作调节投屏显示界面的显示分辨率，包括：
步骤S901，接收用户基于分辨率调节区域的分辨率调节操作；
步骤S902，根据分辨率调节操作向投屏发射端发送分辨率调节请求， 其中，分辨率调节请求中包括目标分辨率；
步骤S903，接收投屏发射端基于分辨率调节请求发送的投屏内容，其中，投屏内容的分辨率为目标分辨率。
在本公开实施例中，如上述实施例，可以通过投屏接收端或者遥控设备接收用户基于分辨率调节区域的分辨率调节操作，并基于该分辨率调节操作向投屏发射单发射分辨率调节请求，其中，该分辨率调节请求中包含有目标分辨率，投屏发射端基于该分辨率调节请求将投屏内容的分辨率调节至该目标分辨率，并将调节后的投屏内容发送至投屏接收端进行投屏显示。
本公开实施例通过分辨率调节区域接收用户的分辨率调节操作，并基于该操作向投屏发射端发送分辨率调节请求，以使投屏发射端将投屏内容的分辨率调节至目标分辨率，用户使用方便。
本公开实施例提供了一种可能的实现方式，在该实现方式中，投屏显示界面设置有发射端显示控件，如图10所示，该方法还包括：
步骤S1001，检测投屏显示界面中正在或将要显示的投屏内容的发射端；
步骤S1002，通过发射端显示控件显示发送正在或将要显示的投屏内容的发射端的标识信息。
在本公开实施例中，投屏显示界面设置有发射端显示控件，可以通过该控件显示投屏内容发射端的标识信息。
对于本公开实施例，为方便说明，以一个具体实施例为例，如图11所示，投屏显示界面1101中显示有投屏内容1102和发射端显示控件1103，其中，发射端显示控件用于显示该投屏内容发射端的标识信息。具体的，在进行投屏时，投屏接收端在接收投屏发射端发送的投屏内容时，会获取该投屏发射端的标识信息，并在对该投屏内容进行展示时，在发射单显示控件中显示该投屏发射端的标识信息。例如，对于一次投屏动作，投屏显示界面显示的投屏发射端A发送的投屏内容，则在对该投屏内容进行显示时，在发射端显示控件中显示投屏发射单A。
本公开实施例通过在投屏显示界面显示发射单显示控件，显示正在显 示的投屏内容对应的发射端的标识信息，便于用户确定投屏源。
本公开实施例提供了一种可能的实现方式，在该实现方式中，如图12所示，投屏显示界面设置有一个或多个投屏显示窗口，每个投屏显示窗口分别设置有状态显示控件，该方法还包括：
步骤S1201，监测一个或多个投屏显示窗口的显示状态；
步骤S1202，通过状态显示窗口显示对应的投屏显示窗口的显示状态。
本公开实施例，通过获取与投屏接收端连接的投屏发射端的数量，并在投屏接收端的显示界面创建与投屏发射端数量相应的投屏显示窗口，通过多个投屏显示窗口同时显示多个投屏内容，适用于多端投屏的场景，用该多个投屏显示窗口对多个投屏发射端发送的投屏内容进行展示，提升用户体验。
在本公开实施例中，投屏接收端在与投屏发射端建立连接的时候，获取投屏发射端的数量，并接收各投屏发射单发送的投屏内容，然后在显示界面创建与该投屏发射端数量对应的投屏显示窗口，通过多个投屏显示窗口分别显示多个投屏发射端发送的投屏内容。
对于本公开实施例，为方便说明，以一个具体实施例为例，用户在通过电脑进行远程投屏时，一个投屏发射端为一台电脑，投屏接收端为具有通信功能的显示设备，如具有通信功能的投影仪，电脑端用户通过电脑向投影仪投屏视频，投影仪对该视频进行展示，在展示过程中，投影仪在检测到与电脑建立连接时，会获取建立连接的电脑的数量，如与投影仪简历连接的电脑有两台，则接收该两台电脑发送的投屏内容，如视频，并在投影仪的显示界面创建两个投屏显示窗口，如图13所示，显示界面1301中包括投屏显示窗口1302和投屏显示窗口1303，且分别对应有状态显示控件1304和状态显示控件1305，投影仪在完成投屏显示窗口的创建之后，通过两个投屏显示窗口分别显示两台电脑发送的投屏内容，如通过投屏显示窗口1302显示第一台电脑发送的投屏内容，通过投屏显示窗口1303显示第二台电脑发送的投屏内容。
对于本公开实施例，投屏显示界面同时显示有多个投屏显示窗口时，检测该多个投屏显示窗口的显示状态，并通过该投屏显示窗口对应的状态 显示控件进行显示。其中，投屏显示窗口的显示状态可以用于指示与投屏发射端的连接状态，比如用于指示是否连接有投屏发射端、将要连接投屏发射端、或已经连接投屏反射端，换言之，显示状态可以包括第一状态、第二状态或第三状态，第一状态用于指示当前窗口没有显示投屏内容，第二状态用于指示当前窗口已被选中将要用于显示投屏内容，第三状态用于指示当前窗口正在显示投屏内容，比如，通过熄灭、点亮或选中来显示各个状态，熄灭代表该投屏显示窗口处于熄灭状态，没有显示投屏内容，点亮标识该投屏显示窗口为打开状态，显示有投屏内容，选中标识该投屏显示窗口被选中，可以对该投屏显示窗口进行操作，其中，各显示状态的表示可以是通过文字进行表示，也可以是通过不同颜色的指示灯进行表示，对此，本公开不做限定。在一例子中，上述显示状态调节区域还可以显示有正在或将要在该窗口显示投屏内容的投屏发射端的标识信息。例如，窗口1被选中将要显示手机1的投屏内容时，可以在高亮窗口1来表示窗口1已被选中，通过在窗口1的显示状态调节区域显示手机1的标识来表示窗口1将要显示的投屏内容是手机1的投屏内容。通过上述第一状态、第二状态或第三状态，便于用户确认当前的投屏信息是否正确，避免选错投屏发射端或投屏窗口，提高投屏准确率和效率。
本公开实施例通过检测投屏显示窗口的显示状态，并通过状态显示控件对窗口显示状态进行显示，便于用户了解各窗口的显示状态。

在本公开实施例中，显示模式是指投屏显示窗口的显示模式，包括电影模式、文本模式等，在不同模式下，投屏显示窗口中显示的投屏内容的显示会不同，如在电影模式下，投屏显示窗口中的显示内容会以高分辨率、高帧率的形式显示，提升观影体验，在文本模式下，投屏显示窗口中的投屏内容会以低分辨率低帧率的形式显示，提升文本显示的响应速度。其中，各个投屏显示窗口的显示模式可以是根据投屏显示界面中投屏显示窗口的数量或各投屏显示窗口的显示内容确定的，如当投屏显示界面中的投屏显示窗口的数量较多时，可以将所有窗口都设置为低分辨率、低帧率的显示形式，或者在某个窗口显示的是电影时，可以将该窗口设置为电影模式。
对于本公开实施例，为方便说明，以一个具体实施例为例，用户在通过电脑进行远程投屏时，一个投屏发射端为一台电脑，投屏接收端为具有通信功能的显示设备，如具有通信功能的投影仪，电脑端用户通过电脑向投影仪投屏视频，投影仪对该视频进行展示，在展示过程中，如投影仪连接有两台电脑，则通过两个投屏显示窗口分别显示两台电脑的投屏内容，其中，电脑1发送的投屏内容为电影，则可以根据投屏内容为电影将电脑1对应的投屏显示窗口的显示模式调节为电影模式，如电脑2发送的投屏内容为文本，则可以根据内容为文本将电脑为对应的投屏显示窗口的显示模式调节为文本模式。可选的，如投影仪连接有8台电脑，则可以根据电脑数量为8，将所有投屏显示窗口的显示模式调节为低分辨率、低帧率的显示模式。
本公开实施例可以根据投屏显示窗口的数量和每个窗口的显示内容自动调节投屏显示窗口的显示模式，适应窗口数量与窗口显示内容，为客户提供更好的观看体验。
本公开实施例提供了一种可能的实现方式，在该实现方式中，显示状态调节区域设置有显示模式调节区域，显示状态调节操作包括显示模式调节操作，基于显示状态调节操作调节投屏显示界面的显示状态，包括：

检测一个或多个投屏显示窗口显示的投屏显示内容；
基于一个或多个投屏显示窗口显示的投屏内容调节相应的投屏显示窗口的显示模式。
在本公开实施例中，投屏接收端可以定期或在满足一定条件时检测各投屏显示窗口的显示内容，当某个投屏显示窗口的显示内容的种类发生变化时，可以调节该窗口的显示模式与变化后的显示内容对应。
对于本公开实施例，为方便说明，以一个具体实施例为例，用户在通过电脑进行远程投屏时，一个投屏发射端为一台电脑，投屏接收端为具有通信功能的显示设备，如具有通信功能的投影仪，电脑端用户通过电脑向投影仪投屏视频，投影仪对该视频进行展示，在展示过程中，如投影仪连接有两台电脑，则通过两个投屏显示窗口分别显示两台电脑的投屏内容，其中，电脑1和电脑2发送的投屏都是文本，则两个投屏显示窗口的显示模式都是文本模式，投影仪对两个投屏窗口的投屏内容定期进行检查，当检测到窗口1显示的内容变化为电影时，将窗口1的显示模式调节为电影模式。
在本公开实施例中，投屏接收端通过对投屏显示窗口中显示的投屏内容进行监控，当投屏显示窗口中的投屏内容的种类发生改变时，自动将对应的投屏显示窗口的显示模式调节为与变化后的显示内容适应的显示模式，提升用户观看体验。
本公开实施例提供了一种可能的实现方式，在该实现方式中，投屏显示界面设置有一个或多个投屏显示窗口，其中，一个投屏显示窗口可以设置有对应的一个或多个显示参数调节区域。
本公开实施例提供了一种可能的实现方式，在该实现方式中，如图15所示，接收投屏发射端发送的投屏内容，并在投屏接收端的投屏显示界面显示投屏内容，包括：
步骤S1501，检测投屏发射端的数量，并接收各投屏发射端发送的投屏内容；
步骤S1502，在投屏接收端的投屏显示界面创建与投屏发射端的数量一致的投屏显示窗口；
步骤S1503，通过各投屏显示窗口显示对应的投屏发射端发送的投屏内容。
在本公开实施例中，投屏接收端是指用于展示投屏内容的终端，可以是液晶显示器、电子墨水屏、投影仪等显示装置，投屏发射端是指用于将投屏内容发送至投屏接收端的终端，可以是电脑、手机、平板电脑等电子设备，其中，投屏接收端和投屏发射端之间建立通信连接，可以是有线通 信，也可以是无线通信，如图6所示，投屏接收端601与多个投屏发射端602之间建立通信连接，在投屏发射端与投屏接收端建立通信连接时，投屏发射端将投屏内容发送至投屏接收端，投屏接收端对投屏内容进行展示。
本公开实施例，通过获取与投屏接收端连接的投屏发射端的数量，并在投屏接收端的显示界面创建与投屏发射端数量相应的投屏显示窗口，通过多个投屏显示窗口同时显示多个投屏内容，适用于多端投屏的场景，用该多个投屏显示窗口对多个投屏发射端发送的投屏内容进行展示，提升用户体验。
在本公开实施例中，投屏接收端在与投屏发射端建立连接的时候，获取投屏发射端的数量，并接收各投屏发射单发送的投屏内容，然后在显示界面创建与该投屏发射端数量对应的投屏显示窗口，通过多个投屏显示窗口分别显示多个投屏发射端发送的投屏内容。
对于本公开实施例，为方便说明，以一个具体实施例为例，用户在通过电脑进行远程投屏时，一个投屏发射端为一台电脑，投屏接收端为具有通信功能的显示设备，如具有通信功能的投影仪，电脑端用户通过电脑向投影仪投屏视频，投影仪对该视频进行展示，在展示过程中，投影仪在检测到与电脑建立连接时，会获取建立连接的电脑的数量，如与投影仪简历连接的电脑有两台，则接收该两台电脑发送的投屏内容，如视频，并在投影仪的显示界面创建两个投屏显示窗口。
本公开实施例通过获取与投屏接收端连接的投屏发射端的数量，并在投屏接收端的显示界面创建与投屏发射端数量相应的投屏显示窗口，通过多个投屏显示窗口同时显示多个投屏内容，适用于多端投屏的场景，用该多个投屏显示窗口对多个投屏发射端发送的投屏内容进行展示，提高了投屏效率，从而提升用户体验。
本公开实施例中提供了再一种投屏方法，该方法的流程示意图如图16所示，该方法包括：
S1601，接收多窗口显示指令，在至少两个目标窗口上显示目标投屏源向投屏设备投射的投屏信息，其中，目标窗口为投屏设备上的已开启的至少两个窗口中的一个，目标投屏源为与投屏设备实现连接的至少一个投 屏源中的一个。本公开实施例中，投屏信息包括各类媒体信息、实时操作画面等。
本公开实施例中，多窗口显示指令用于指示至少两个窗口上同时显示同一个投屏源向投屏设备投射的投屏信息。例如，同时开启投屏设备上的三个窗口，投屏设备与一个投屏源处于连接状态，多窗口显示指令指示这三个窗口上显示该投屏源向投屏设备投射的投屏信息，即这三个窗口都同时显示相同的投屏信息。
本公开实施例中，步骤S1601中的“在至少两个目标窗口上显示目标投屏源向投屏设备投射的投屏信息”，可以包括：
当第一数量大于第二数量时，在至少两个目标窗口上显示目标投屏源向投屏设备投射的投屏信息；
其中，第一数量是开窗口指令指示的开启的窗口数量，第二数量是开连接指令指示的投屏设备连接的投屏源的数量。
例如，投屏设备与两个投屏源处于连接状态，第二数量为2，两个投屏源分别是A投屏源和B投屏源。开启投屏设备上的三个窗口，三个窗口分别A窗口、B窗口和C窗口，即第一数量为3。A窗口上显示A投屏源向投屏设备投射的投屏信息；B窗口上显示A投屏源或B投屏源向投屏设备投射的投屏信息；C窗口上显示B投屏源向投屏设备投射的投屏信息。
本公开实施例中，第一数量可以为投屏设备上的全部窗口的数量，第二数量可以为1。
本公开实施例中，在响应开连接指令后，投屏设备与一个投屏源处于连接状态，第二数量为1。在响应开窗口指令后，开启投屏设备上的三个窗口，即第一数量为3。若收到多窗口显示指令，则在开启的三个窗口上显示该投屏源向投屏设备投射的投屏信息。
本公开实施例中，投屏设备与一个投屏源处于连接状态，三个窗口都显示该投屏源所投射的相同的投屏信息。例如，会议室里有一个长方形100多寸的LED屏幕，LED屏幕左中右的位置并排分别显示三个窗口，这3个窗口同时显示同一个投屏源所投射的相同的投屏信息；这样会议室里不同视角的参会人员都可以看到相同的投屏信息。
本公开实施例中，获取关连接指令；若关连接指令指示投屏设备与目标投屏源断开连接、且目标投屏源是唯一一个与投屏设备连接的投屏源，则将投屏设备上的全部窗口进行关闭。
例如，投屏设备总共有三个窗口，这三个窗口都开启，若唯一一个与投屏设备连接的投屏源主动或被动断开连接，则自动关闭这三个窗口；投屏源的标签显示灰色，表示熄灭。
本公开实施例中，接收多窗口显示指令，在至少两个目标窗口上显示目标投屏源向投屏设备投射的投屏信息，其中，目标窗口为投屏设备上的已开启的至少两个窗口中的一个，目标投屏源为与投屏设备实现连接的至少一个投屏源中的一个。如此，实现了在同一个投屏设备上打开多个窗口，多个窗口都显示同一个投屏源向投屏设备投射的投屏信息，这样不同视角的用户都可以看到相同的投屏信息，提升了用户体验。
本公开实施例中提供了另一种投屏方法，该方法的流程示意图如图17所示，该方法包括：
S1701，接收显示切换指令，在目标窗口切换显示至少两个目标投屏源向投屏设备投射的投屏信息，目标窗口为投屏设备上的已开启的至少一个窗口中的一个，目标投屏源为与投屏设备实现连接的至少两个投屏源中的一个。
本公开实施例中，显示切换指令用于指示同一窗口从显示投屏信息A切换到显示投屏信息B，其中，投屏信息A为一个投屏源向投屏设备投射的投屏信息，投屏信息B为另一个投屏源向投屏设备投射的投屏信息。
例如，开启投屏设备上的一个窗口，投屏设备与1号投屏源、2号投屏源以及3号投屏源处于连接状态，投屏设备的这个窗口上的三个投屏源的标签分别是设备1、设备2和设备3。该窗口显示投屏信息A，其中，投屏信息A为设备1对应的1号投屏源向投屏设备投射的投屏信息；用户点击设备2，即触发了显示切换指令，显示切换指令指示该窗口从显示投屏信息A切换到显示投屏信息B，其中，投屏信息B为设备2对应的2号投屏源向投屏设备投射的投屏信息；用户再点击设备3，即触发了显示切 换指令，显示切换指令指示该窗口从显示投屏信息B切换到显示投屏信息C，其中，投屏信息C为设备3对应的3号投屏源向投屏设备投射的投屏信息。
本公开实施例中，步骤S1701中的“在目标窗口切换显示至少两个目标投屏源向投屏设备投射的投屏信息”，可以包括：
当存在至少两个不同的目标窗口时，在不同的目标窗口上，同步或异步的切换显示至少两个目标投屏源向投屏设备投射的投屏信息。
本公开实施例中，三个投屏源与投屏设备保持连接，三个投屏源在无线投屏，该投屏设备的三个窗口都开启，每一个窗口都可以实现切换显示三个投屏源向投屏设备投射的投屏信息。三个窗口可以同时显示同一个投屏源向投屏设备投射的投屏信息，三个窗口也可以分别显示三个投屏源向投屏设备投射的投屏信息。
本公开实施例中，在同一个窗口里切换不同的投屏源。例如，三个窗口中只开启了一个窗口，这三个投屏源在无线投屏，则三个投屏源都可以不断开，可以实现三个投屏源向投屏设备投射的投屏信息在这个窗口里进行切换显示。三个窗口中的每个窗口都可以对应三个投屏源标签，从而若可以在每个窗口开启后，都可以在该窗口内切换不同的投屏源。
本公开实施例中，获取关窗口指令；若关窗口指令指示关闭至少一个已开启窗口、且没有关闭所有的已开启窗口，则保持投屏设备与每一已连接投屏源之间的连接状态；若关窗口指令指示关闭全部的已开启窗口，则断开投屏设备与每一已连接投屏源之间的连接；其中，已开启窗口是开窗口指令指示开启的窗口，已连接投屏源是开连接指令指示连接的投屏源。
本公开实施例中，当开连接指令指示投屏设备与多个投屏源进行连接，且开窗口指令指示开启投屏设备上的A窗口，在A窗口上显示多个投屏源中一个投屏源向投屏设备投射的投屏信息，当多个投屏源中B投屏源与投屏设备断开时，A窗口上显示多个投屏源中除B投屏源之外的任一投屏源；或，A窗口上显示多个投屏源中除B投屏源之外的最后与投屏设备连接的C投屏源；从而在断开B投屏源后，灵活的在同一窗口内切换其他的投屏 源。
本公开实施例中，三个投屏源与投屏设备保持连接，这三个投屏源在无线投屏，该投屏设备的三个窗口都开启。投屏设备获取关窗口指令；关窗口指令指示投屏设备关闭三个窗口中一个或两个窗口，则这三个投屏源都可以不与投屏设备断开；当三个窗口都关闭，则这三个投屏源都与投屏设备断开。
本公开实施例中，A、B和C三个投屏源与投屏设备保持连接，该投屏设备的三个窗口都开启，投屏设备接收到关窗口指令，关窗口指令指示关闭这三个窗口中两个窗口，投屏设备只开启了1个窗口显示A投屏源向投屏设备投射的画面，此时A投屏源主动断开，则不关闭当前窗口，当前窗口自动切换至B投屏源或C投屏源向投屏设备投射的画面，B投屏源或C投屏源是A、B和C三个投屏源中最后一个与投屏设备进行连接的设备。
本公开实施例中，当有两个或三个投屏源与投屏设备保持连接，投屏设备只开启了1个窗口；投屏设备获取关窗口指令；关窗口指令指示投屏设备关闭该窗口，则该窗口关闭前弹出对话框，对话框显示的内容包括：“关闭应用将断开所有连接，如需断开当前连接，请点击返回键。是否断开所有连接？确定/返回”。
本公开实施例中，接收显示切换指令，在目标窗口切换显示至少两个目标投屏源向投屏设备投射的投屏信息，目标窗口为投屏设备上的已开启的至少一个窗口中的一个，目标投屏源为与投屏设备实现连接的至少两个投屏源中的一个。如此，实现了针对同一个窗口可以切换不同的投屏源，从而使用户通过同一个窗口可以看到不同的投屏源向投屏设备投射的投屏信息，提升了用户体验。
