具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
在本文中提及的“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
相关技术中，在源端设备向目的端设备进行投屏的过程中，源端设备需要始终保持亮屏工作状态，一旦进入熄屏状态，源端设备将中断与目的端设备之间的连接，结束投屏。
在一种可能的场景中，源端设备向目的端设备进行镜像投屏的过程中，在用户通过目的端设备对投屏画面进行操作，而不再通过源端设备进行操作的情况下，源端设备仍然需要保持亮屏状态，一旦源端设备进入熄屏状态，将会导致源端设备与目的端设备之间的连接中断，进而投屏失败。因此，在投屏过程中，用户需要间歇性地对源端设备进行操作(比如触屏操作)，或者手动关闭源端设备的自动熄屏功能，以此来避免源端设备进入熄屏状态。然而，源端设备保持亮屏状态又会导致功耗增加，增大耗电量。
本申请实施例中，针对上述问题，在进行投屏的过程中，源端设备自动延长熄屏时长，并在未达到延长后熄屏时长的情况下，控制屏幕熄灭，使得在仅熄灭屏幕而不进入熄屏状态的情况下，能够保持与目的端设备之间的投屏数据流传输，既降低了源端设备的功耗，又避免因源端设备自动进入熄屏状态导致投屏中断。
图1示出了本申请一个示例性实施例提供的实施环境的示意图。该实施环境包括源端设备101和目的端设备102。
源端设备101是具有投屏功能的电子设备，其中，该投屏功能可以为电子设备中原生应用，或者，第三方应用的功能；目的端设备102是具有投屏显示功能的电子设备，其中，该 投屏显示功能可以为电子设备中原生应用，或者，第三方应用的功能。该电子设备可以是智能手机、平板电脑、个人计算机、可穿戴式设备或车载终端等等，图1中，以源端设备101为智能手机、目的端设备102为电视终端为例进行说明，但并不对此构成限定。
在一种可能的实施方式中，源端设备101和目的端设备102位于同一局域网下，并通过该局域网进行投屏数据流传输。
如图1所示，源端设备101和目的端设备102同时连接在路由器103提供的同一局域网下，从而通过路由器103进行投屏数据流传输。
在源端设备101向目的端设备102进行投屏的过程中，源端设备101对屏幕画面进行录制，并采集设备音频，从而对录制画面和音频进行编码，生成音视频数据流，进而通过路由器103将该音视频数据流传输至目的端设备102，由目的端设备102对音视频数据流进行解码播放。此外，当支持反向控制功能时，目的端设备102可以通过路由器103向源端设备101传输反向控制指令，源端设备101即根据该反向控制指令执行相应的反向控制操作。
需要说明的是，源端设备101和目的端设备102连接在同一局域网下的方式，可以是同时连接在同一路由器下，也可以是其他可能的方式，本申请实施例对此并不进行限定。并且，在其他可能的实施方式中，源端设备101和目的端设备102也可以通过互联网进行投屏，本实施例对此不作限定。
此外，源端设备101可以同时向多个具有投屏功能的目的端设备102传输投屏数据流(即一对多投屏)，目的端设备102也可以同时接收多个源端设备101的投屏数据流(即多对一投屏)，本申请实施例仅以一对一投屏为例进行示意性说明，但对此并不构成限定。
请参考图2，其示出了本申请一个示例性实施例提供的投屏方法的流程图。本申请实施例以该方法用于图1所示的源端设备为例进行说明，该方法可以包括如下步骤：
步骤201，投屏状态下，将熄屏时长由第一时长设置为第二时长，熄屏时长是源端设备自动进入熄屏状态的时长，第二时长大于第一时长。
由于源端设备在长时间没有接收到保持亮屏操作(比如触屏操作)或者事件(比如来电通知)的情况下，仍然保持屏幕点亮状态会导致功耗增加，因此为了降低功耗，源端设备可以设置熄屏时长，并在达到熄屏时长的情况下，自动进入熄屏状态。
在该熄屏状态下，源端设备将调低或者关闭一部分电压的输出，并将正在运行的应用数据保存在存储器中，对切换至后台运行的应用进行监听，熄灭屏幕并保持屏幕进入锁定状态。只有接收到对屏幕的解锁操作，源端设备才能点亮屏幕并在前台继续应用的运行。
可选的，非投屏状态下，源端设备的熄屏时长被设置为第一时长。即在非投屏状态下，若在第一时长内未接收到保持亮屏操作或者事件，源端设备自动进入熄屏状态。
为了避免在投屏状态下，在达到第一时长且未接收到保持亮屏操作或者事件的情况下，源端设备自动进入熄屏状态，源端设备在进入投屏状态的同时，自动将熄屏时长由第一时长设置为第二时长，其中，该第二时长大于第一时长。通过设置该第二时长，可以延长源端设备自动进入熄屏状态的时间，避免因源端设备短时间内进入熄屏状态导致的投屏中断问题。
可选的，第二时长可以是源端设备支持设置的熄屏时长候选值中的最大值，比如，该第二时长为整型(int)最大值。或者，在源端设备关闭自动熄屏功能的情况下，将熄屏时长设置为第二时长时，源端设备将不会进入熄屏状态，即自动熄屏功能关闭。
可选的，投屏状态指的是镜像投屏状态。源端设备通过对屏幕进行录制，得到录屏画面，并通过目的端设备显示该录屏画面。
示意性的，如图3所示，非投屏状态下，源端设备301自动进入熄屏状态的时长为2分钟，在开启投屏功能向目的端设备302进行投屏时，源端设备301自动将进入熄屏状态时长延长为整型(int)最大值，从而，源端设备301将不会进入熄屏状态，即自动熄屏功能关闭。
步骤202，在达到目标时长的情况下，控制屏幕熄灭，其中，屏幕熄灭后源端设备未进入熄屏状态，目标时长小于第二时长。
不同于相关技术中，源端设备在延长自动熄屏时长后，屏幕始终处于亮屏状态。本实施例中，为了降低源端设备的功耗，在延长熄屏时长的前提下，源端设备在达到目标时长的情况下，能够控制屏幕熄灭，而未进入熄屏状态，以此降低功耗。
可选的，目标时长小于第二时长，可以是第一时长，也可以是其他小于第二时长的时长。在目标时长为第一时长的情况下，控制屏幕熄灭的时长与源端设备自动进入熄屏状态的时长相同，从而给用户提供一种类似进入熄屏状态的控制屏幕熄灭的过程，就用户体验而言，源端设备屏幕熄灭的过程与进入熄屏状态时屏幕熄灭的过程一致。
在一种可能的实施方式中，源端设备设置倒计时时长为目标时长的倒计时器，并在倒计时器到时后，控制屏幕熄灭。
上述过程中，由于对源端设备的熄屏时长进行延长，因此在没有达到第二时长的情况下，源端设备将不会自动进入熄屏状态。而通过在达到目标时长的情况下，源端设备能够控制屏幕熄灭，不仅避免了源端设备功耗过大，而且就用户体验而言，源端设备屏幕熄灭的过程与进入熄屏状态时屏幕熄灭的过程相似。
可选的，控制屏幕熄灭的方式可以是将屏幕亮度调为零，也可以是对屏幕单独停止供电等，本申请实施例对此并不进行限定。
在一种可能的实施方式中，源端设备控制屏幕熄灭，且未进入熄屏状态，屏幕处于未锁定状态，同时源端设备保持录屏投屏状态。
示意性的，如图3所示，在2分钟内未接收到操作的情况下，源端设备301熄灭屏幕，且未进入熄屏状态，保持投屏状态。
步骤203，在屏幕熄灭且未达到第二时长的情况下，保持与目的端设备之间的投屏数据流传输。
在屏幕熄灭且未达到第二时长的情况下，由于源端设备并未进入熄屏状态，因此源端设备能够保持与目的端设备之间的投屏数据流传输，其中，该投屏数据流包括源端设备向目的端设备发送的音视频数据流和目的端设备向源端设备发送的反向控制指令。
示意性的，如图3所示，在未达到延长后的熄屏时长的情况下，源端设备301继续保持与目的端设备302之间的投屏数据流传输，目的端设备302继续对录屏画面进行显示。
综上所述，本申请实施例中，投屏状态下，源端设备将自动进入熄屏状态的熄屏时长由第一时长延长为第二时长，并在达到目标时长的情况下，控制屏幕熄灭，该目标时长小于第二时长，由于在未达到第二时长的情况下，源端设备仅将屏幕熄灭而未进入熄屏状态，因此源端设备能够保持与目的端设备之间的投屏数据流传输。采用本申请实施例提供的方案，源端设备能够在投屏状态下，自动延长熄屏时长，在屏幕熄灭但未进入熄屏状态的情况下，保持与目的端设备之间的投屏数据流传输，既保证了源端设备与目的端设备之间的正常投屏，又能够避免源端设备因长时间亮屏造成的功耗增加，有助于降低投屏过程中源端设备的功耗。

可选的，方法还包括：
在退出投屏状态的情况下，将熄屏时长设置为第一时长。
通常情况下，源端设备由亮屏状态自动进入熄屏状态的过程中，包含屏幕由亮变暗再到熄灭的过程。本申请实施例中，为了提升用户体验，源端设备控制屏幕熄灭的过程可以和源端设备自动进入熄屏状态所表现的屏幕熄灭过程保持一致，下面通过具体的实施例对源端设备控制屏幕熄灭的过程以及在屏幕熄灭情况下的工作状态进行详细说明。
请参考图4，其示出了本申请另一个示例性实施例提供的投屏方法的流程图。本实施例以该方法用于图1所示的源端设备为例进行说明，该方法可以包括如下步骤：
步骤401，投屏状态下，将熄屏时长由第一时长设置为第二时长，熄屏时长是源端设备自动进入熄屏状态的时长，第二时长大于第一时长。
本步骤的实施方式可以参考上述步骤201，本实施例在此不作赘述。
步骤402，在达到第三时长的情况下，将屏幕亮度由第一亮度调整为第二亮度，第三时长小于目标时长，第二亮度小于第一亮度。
按照通常情况下源端设备自动进入熄屏状态过程中所表现的屏幕熄灭过程，源端设备设置第三时长，在达到第三时长的情况下，源端设备将屏幕亮度由第一亮度调整为第二亮度，从而模拟出源端设备自动进入熄屏状态过程中屏幕变暗的过程。
可选的，第三时长与目标时长之间的差值为固定值。比如，该固定值为5秒，当目标时长为1分钟时，第三时长为55秒；当目标时长为30秒时，第三时长为25秒。在一种可能的实施方式中，源端设备基于目标时长和固定值确定第三时长，从而设置倒计时时长为第三时 长的倒计时器，并启动倒计时器，从而在倒计时器到时后，将屏幕亮度由第一亮度调整为第二亮度。
为了保证不同环境下的屏幕显示效果，用户一般会将屏幕的亮度调节模式设置为第一调节模式(或称为自动调节模式)。第一调节模式下，基于环境光亮度自动调整屏幕亮度的功能开启，源端设备根据其所处环境的环境光亮度(可以通过环境光传感器采集得到)对屏幕亮度进行自动调节，在用户手动调节屏幕亮度的情况下，源端设备依然会根据其所处环境的环境光亮度对屏幕亮度进行调节。而本申请实施例中，由于需要将屏幕亮度由第一亮度调整为第二亮度，因此为了保证屏幕亮度调整过程的正常执行(不会因第一调节模式导致调整后的第二亮度发生变化)，在一种可能的实施方式中，亮度调整过程可以包括如下步骤：
1、在亮度调节模式为第一调节模式的情况下，将亮度调节模式设置为第二调节模式。
在一种可能的实施方式中，源端设备确定当前的亮度调节模式。若当前的亮度调节模式为第一调节模式，则将亮度调节模式修改为第二调节模式(或称为手动调节模式)，其中，第二调节模式下，基于环境光亮度自动调整屏幕亮度的功能关闭，源端设备并不会根据环境光亮度自动调整屏幕亮度，在用户手动调节屏幕亮度的情况下，源端设备不会根据其所处环境的环境光亮度对屏幕亮度进行调节。若当前的亮度调节模式为第二调节模式，则保持第二调节模式。
需要说明的是，亮度调节模式的设置过程由源端设备在后台自动执行，用户侧并不会感知。
2、在第二调节模式下，自动将屏幕亮度由第一亮度调整为第二亮度。
进一步的，在第二调节模式下，源端设备自动将屏幕亮度由第一亮度调整为第二亮度。由于第二调节模式下，屏幕亮度不会随着环境光亮度改变而改变，因此屏幕亮度被设置为第二亮度后将不会发生变化。
需要说明的是，在源端设备的初始亮度调节模式为第二调节模式的情况下，源端设备直接将第一亮度调整为第二亮度。
在一些实施例中，第二亮度为固定值，且该第二亮度为正常进入熄屏状态前屏幕亮度降低后的亮度。比如，第二亮度为50nit。
在一个示意性的例子中，当目标时长为1分钟时，在达到55秒时，源端设备将亮度调节模式设置为第二调节模式，并将屏幕亮度由1000nit调整为50nit。
正常自动熄屏流程中，在进入熄屏状态前，若用户对设备进行操作或者设备接收到特定通知时，设备需要保持亮屏。为了模拟出这一效果，在一种可能的实施方式中，投屏状态下，源端设备进行目标事件监听，在达到第三时长，且未监听到目标事件的情况下，源端设备将屏幕亮度由第一亮度调整为第二亮度，其中，目标事件具有保持源端设备的屏幕处于亮屏状态的功能。
可选的，该目标事件可以是来电通知、消息提醒、触屏操作、语音控制指令等，本申请实施例对此并不进行限定。
可选的，若在未达到第三时长的情况下监听到目标事件，源端设备对目标事件进行响应，并保持第一亮度。
在一种可能的实施方式中，源端设备设置倒计时时长为第三时长的倒计时器，并启动该倒计时器。若在倒计时过程中未监听到目标事件，则倒计时器到时后，将屏幕亮度调整为第二亮度；若在倒计时过程中监听到目标事件，则在监听到目标事件时重置倒计时器，并保持屏幕亮度为第一亮度。
示意性的，如图5所示，源端设备501设置目标时长为1分钟，第三时长为55秒，在达到第三时长，且未监听到触控操作以及来电通知的情况下，源端设备501将屏幕亮度由第一亮度1000nit调整为第二亮度50nit。
在一种可能的实施方式中，在达到第三时长且未达到目标时长，且监听到目标事件的情况下，源端设备将屏幕亮度调整为第一亮度。
在达到第三时长，而未达到目标时长的情况下，源端设备监听到目标事件，为了便于用户进行后续操作处理，源端设备将屏幕亮度恢复为第一亮度。
示意性的，如图5所示，源端设备501监听到触屏操作的情况下，将屏幕亮度从50nit调整为1000nit，从而方便用户进行后续操作处理。
步骤403，在达到目标时长，且未监听到目标事件的情况下，控制屏幕熄灭，目标事件具有保持源端设备的屏幕处于亮屏状态的功能。
在一种可能的实施方式中，投屏状态下，源端设备设置倒计时时长为目标时长的倒计时器，并启动该倒计时器。若在倒计时过程中未监听到目标事件，则倒计时器到时后，控制屏幕熄灭。
其中，目标事件具有保持源端设备的屏幕处于亮屏状态的功能，该目标事件可以由用户对源端设备的操作触发，比如用户对源端设备的触屏操作所触发的触控事件，也可以由源端设备接收到的通知触发，比如源端设备接收到的来电通知。
示意性的，如图5所示，源端设备501若在目标时长内未监听到触屏操作以及来电通知，则在达到目标时长时控制屏幕熄灭。
步骤404，在目标时长内监听到目标事件的情况下，保持屏幕处于亮屏状态，并重置倒计时器，倒计时器的倒计时时长为目标时长。
在一种可能的实施方式中，在倒计时过程中(倒计时器的倒计时时长为目标时长)监听到目标事件的情况下，为了方便用户进行后续操作处理，源端设备保持屏幕处于亮屏状态，并在监听到目标事件时重置倒计时器。
在一种可能的实施方式中，若在第三时长内未监听到目标事件，源端设备对当前的亮度调节模式以及第一亮度进行保存。若在达到第三时长但未达到目标时长的情况下监听到目标事件，源端设备则恢复保存的亮度调节模式，并将屏幕亮度恢复为第一亮度。
步骤405，在屏幕熄灭且未达到第二时长的情况下，保持与目的端设备之间的投屏数据流传输。
本步骤的实施方式可以参考上述步骤203，本实施例在此不作赘述。
步骤406，在屏幕熄灭且未达到第二时长的情况下，接收目的端设备发送的反向控制指令，反向控制指令用于对源端设备进行反向控制。
在屏幕熄灭且未达到第二时长的情况下，当用户通过目的端设备在投屏画面上进行操作时，目的端设备将用户操作以反向控制指令的形式发送至源端设备，进一步的，源端设备接收该反向控制指令，从而执行相应的反向控制操作。
在一种可能的实施方式中，目的端设备接收用户在投屏画面上的操作指令，可选的，目的端设备接收用户对屏幕的触控操作，或者通过外设(比如鼠标、键盘等)接收操作指令。在接收到操作指令之后，目的端设备对该操作指令进行识别，转化为对源端设备的反向控制指令，并向源端设备发送该反向控制指令。
其中，反向控制指令中包含操作类型以及对应的操作参数。比如，当目的端设备接收到来自鼠标的点击操作时，反向控制指令包括操作类型“点击”、该点击操作对应点击坐标以及该点击操作的点击次数；当目的端设备接收到滑动操作时，反向控制指令包括操作类型“滑动”以及滑动操作的滑动轨迹坐标；当目的端设备接收到长按操作时，反向操作指令包括操作类型“长按”、该长按操作对应在的长按坐标以及长按时长等。本申请实施例并不对反向控制指令中包含的具体参数进行限定。
步骤407，执行反向控制指令所指示的反向控制操作。
进一步的，源端设备根据反向控制指令，执行其所指示的反向控制操作。相应的，用户通过目的端设备可以看到反向控制操作后更新的投屏画面。
需要说明的是，由于源端设备与目的端设备的屏幕尺寸可能存在差异，因此源端设备在执行反向控制操作前，需要对反向控制指令中的参数进行坐标转换，本实施例在此不作赘述。
并且，本实施例中，通过目的端设备对源端设备进行反向控制的过程中，源端设备的屏 幕保持熄灭。
步骤408，在监听到亮屏事件的情况下，点亮屏幕，其中，点亮后屏幕显示的画面为非锁屏画面，亮屏事件为触发屏幕亮屏的事件。
为了模拟出正常熄屏状态下源端设备点亮屏幕的过程，源端设备在屏幕熄灭的情况下，对亮屏事件进行监听，并在监听到亮屏事件的情况下，点亮屏幕。其中，该亮屏事件为触发屏幕亮屏的事件。
可选的，亮屏事件可以是通过按压物理按键触发的事件，也可以是触控操作所触发的事件，也可以是语音控制指令触发的时间，也可以是特定通知触发的事件(比如来电通知)等，本申请实施例对此并不进行限定。
需要说明的是，屏幕熄灭后，源端设备需要对亮屏事件进行注册，只有在监听到已经注册的亮屏事件的情况下，源端设备才会点亮屏幕。
可选的，注册的亮屏事件可以与唤醒源端设备退出熄屏状态的事件相同，也可以不同，本申请实施例对此并不进行限定。比如，当源端设备支持通过电源键、点击屏幕、消息通知来退出熄屏状态时，注册的亮屏事件可以包括电源键按压事件、屏幕点击事件以及通知事件，也可以仅包括电源键按压事件以及来电通知事件(即指定类型的通知事件)。
在唤醒源端设备退出熄屏状态的情况下，由于仍旧处于锁屏状态，因此源端设备点亮屏幕后会显示锁屏界面，等待解锁操作。而本申请实施例中，投屏状态下，由于源端设备仅控制屏幕熄灭，而未进入熄屏状态(并未进入锁屏状态)，因此在监听到亮屏事件的情况下，源端设备将屏幕点亮，并且点亮后屏幕直接显示当前投屏画面，而非锁屏界面。
在一个示意性的例子中，源端设备将对电源键的按压操作注册为亮屏事件，响应于对电源键的按压操作，源端设备点亮屏幕，直接显示当前投屏画面，而不需要进行解锁操作。
在一个示意性的例子中，为了保证隐私安全，源端设备将来电通知注册为亮屏事件时，在监听到来电通知的情况下，源端设备点亮屏幕，显示来电通话界面。在接听来电的过程中，源端设备首先对录屏画面进行隐私处理，进而对录屏画面进行编码，生成数据流，传输给目的端设备，其中，隐私处理的方法包括但不限于对来电显示的号码进行马赛克处理。
步骤409，将屏幕亮度设置为第一亮度，并将亮度调节模式设置为第一调节模式。
由于在控制屏幕熄灭的过程中，在屏幕亮度调节模式为第一调节模式的情况下，源端设备对亮度调节模式以及屏幕亮度进行了调整，因此为了保证点亮屏幕后与屏幕熄灭前屏幕亮度以及亮度调节模式的一致性，源端设备将屏幕亮度设置为第一亮度，并将亮度调节模式重新设置为第一调节模式。
进一步的，源端设备亮屏后，继续执行上述步骤402。
步骤410，在退出投屏状态的情况下，将熄屏时长设置为第一时长。
由于设置第二时长是为了在投屏状态下，避免源端设备快速进入熄屏状态，因此在退出投屏状态的情况下，为了降低功耗，源端设备将熄屏时长由第二时长调整为第一时长，即恢复为正常使用状态下，源端设备自动进入熄屏状态的时长。需要说明的是，若在屏幕熄灭过程中退出投屏状态，源端设备需要恢复亮度调节模式以及屏幕亮度。
可选的，退出投屏状态可以由目的端设备触发，比如，当接收到目的端设备发送的退出投屏指令时，源端设备退出投屏状态；或者，退出投屏状态也可以由源端设备触发，比如，当接收到投屏退出操作时，源端设备退出投屏状态；或者，退出投屏状态可以在投屏链路断开时自动触发，比如，因网络原因导致投屏链路断开时，源端设备退出投屏状态。
上述实施例中，在投屏状态下，通过设置第三时长以及对目标事件进行监听，源端设备能够将控制屏幕熄灭的过程与进入熄屏状态时屏幕熄灭的过程表现一致，提升了用户的使用体验，并且在监听到亮屏事件的情况下，源端设备能够直接显示该亮屏事件所在界面，省略了解锁屏幕的步骤，方便用户及时进行后续处理。
需要说明的是，上述实施例仅为一种可能的控制逻辑，在其他可能的实施方式中，在控制屏幕熄灭之后，源端设备对亮屏事件的监听和接收目的端设备发送的反向控制指令可以同 时进行，本申请实施例并不对具体的控制逻辑构成限定。
根据上述实施例，如图6所示，其示出了本申请另一个示例性实施例提供的投屏状态下屏幕熄灭之后的工作流程图。在投屏状态下源端设备601控制屏幕熄灭之后，保持与目的端设备602之间的投屏数据流传输。在源端设备601将来电通知和对电源键的触发操作注册为亮屏事件的情况下，源端设备601依次对事件进行判断，首先判断是否接收到反向控制指令，在接收到反向控制指令的情况下，源端设备601执行反向控制指令所指示的反向控制操作，并保持屏幕熄灭；在没有接收到反向控制指令的情况下，继续判断是否监听到来电通知，在监听到来电通知的情况下，源端设备601点亮屏幕，显示来电通知；在没有监听到来电通知的情况下，继续判断是否监听到音量键触发操作，在监听到音量键触发操作的情况下，源端设备601根据音量键触发操作对音量进行调节，并保持屏幕熄灭；在没有监听到音量键触发操作的情况下，继续判断是否监听到电源键的触发操作，在监听到电源键的触发操作的情况下，源端设备601点亮屏幕，直接显示投屏画面，在没有监听到电源键的触发操作的情况下，源端设备601保持屏幕熄灭。
需要说明的是，上述实施例仅用于示意性说明，在其他可能的实施方式中，源端设备判断事件的过程中，可以同时对接收反向控制指令、监听来电操作、监听音量键触发操作以及监听电源键的触发操作进行判断，也可以按照不同于图6所示的判断顺序进行判断，本申请实施例对此并不构成限定。
不同于相关技术中，在投屏过程中，响应于源端设备的锁屏事件，目的端设备断开与源端设备的连接，退出投屏状态，再次投屏需要重新进行投屏连接。本申请实施例中，在源端设备响应于锁屏事件，进入熄屏状态的情况下，目的端设备保持与源端设备的连接状态，显示锁屏提示画面，用以提示用户源端设备处于锁屏熄屏状态。在源端设备解锁屏幕之后，目的端设备接口恢复显示投屏画面。
在目标时长内监听到锁屏事件的情况下，源端设备进入熄屏状态，其中，熄屏状态下源端设备与目的端设备之间的投屏数据流传输中断。
在一种可能的实施方式中，在目标时长内监听到锁屏事件的情况下，源端设备进入锁屏熄屏状态，停止对画面的录屏操作，中断与目的端设备之间的投屏数据流传输，并对后台运行的应用进行监听。
可选的，锁屏事件可以是由物理按键触发的事件(比如按压电源键)，也可以是语音控制指令触发的事件等，本申请实施例对此并不进行限定。
如图7所示，该过程具体包括以下步骤：
步骤701，在目标时长内监听到锁屏事件的情况下，向目的端设备发送锁屏消息，以便目的端设备基于锁屏消息显示锁屏提示画面。
在一种可能的实施方式中，在目标时长内监听到锁屏事件的情况下，源端设备向目的端设备发送锁屏消息，提示目的端设备投屏数据流中断，即将进入锁屏熄屏状态。
其中，该锁屏消息可以是源端设备向目的端设备传输的投屏数据流中的一条指令，指示目的端设备显示预先设置的锁屏提示画面；也可以是投屏数据流中包含的锁屏提示图像，目的端设备基于该图像显示锁屏提示画面。在目的端设备对投屏数据流进行解码，生成投屏画面的过程中，当目的端设备监听到该指令或该锁屏提示图像时，即为接收到源端设备即将进入锁屏熄屏状态的锁屏消息。
步骤702，进入熄屏状态。
在一种可能的实施方式中，源端设备进入熄屏状态，并中断与目的端设备之间的投屏数据流传输，同时，目的端设备显示锁屏提示画面。
示意性的，如图8所示，源端设备801进入熄屏状态，中断与目的端设备802之间的投屏数据流传输，同时，目的端设备802显示锁屏提示画面。
步骤703，熄屏状态下，在监听到亮屏事件的情况下，点亮屏幕并显示锁屏界面，亮屏事件为触发屏幕亮屏的事件。
在一种可能的实施方式中，源端设备监听到亮屏事件后，点亮屏幕并显示锁屏待解锁界面，此时屏幕亮度设置为第一亮度，并且源端设备继续保持与目的端设备之间投屏数据流的中断。
在达到第四时长，且没有监听到解锁操作的情况下，源端设备将屏幕熄灭，继续保持熄屏状态，其中，该第四时长为等待用户进行解锁操作的亮屏时长。
示意性的，源端设备将来电通知注册为亮屏事件，在监听到来电通知的情况下，源端设备点亮屏幕，显示来电画面，在监听到解锁操作的情况下，来电结束后，源端设备保持亮屏；在来电结束之后且未监听到解锁操作的情况下，源端设备仍然保持熄屏状态。
步骤704，在解锁成功的情况下，恢复与目的端设备之间的投屏数据流传输。
在一种可能的实施方式中，在解锁成功的情况下，源端设备继续对屏幕画面进行录制，并采集设备音频，从而对录制画面和音频进行编码，生成音视频数据流，并将生成的音视频数据流传输给目的端设备。目的端设备在接收到音视频数据流的情况下，结束显示锁屏提示画面，重新对投屏画面进行显示。同时，源端设备接收来自目的端设备的反向控制指令，并执行该反向控制指令所指示的反向控制操作。
示意性的，如图8所示，在解锁成功的情况下，源端设备801继续对屏幕画面进行录制，并采集设备音频，并将生成的音视频数据流传输给目的端设备802，目的端设备802直接对投屏画面进行显示。
