在本申请中，由于具有显示屏的设备能够先后接收第一设备和第二设备发送的内容投屏请求，并能分屏显示第一内容和第二内容。其中，第一设备和第二设备均是在执行预设交互操作后向具有显示屏的 设备发送相应的内容投屏请求。因此，本申请能够降低具有显示屏的设备同时显示多个设备投屏的内容的操作复杂度，并提高了多设备投屏的效率。
为了本申请实施例所示方案易于理解，下面对本申请实施例中出现的若干名词进行介绍。
第一内容投屏请求：是第一设备发送给具有显示屏的设备的信息，用于请求将第一设备中播放的第一内容在具有显示屏的设备中播放。在一种可能的方式中，该第一内容投屏请求可以是符合固定格式的字符串，该字符串中包含关键字和字符内容。
可选地，当预设交互操作是扫描投屏标签，投屏标签是具有显示屏的设备对应的电子标签。字符内容中可以包括第一字符串，该第一字符串是第一设备读取到的信息，该信息是存储在遥控设备的投屏标签中的信息，投屏标签是用于遥控具有显示屏的设备中的标签。例如，第一设备中设备有NFC(Near Field Communication，进场通信)模块。在贴近具有显示屏的设备的遥控器时，第一设备能够读取遥控器中的NFC标签中的第一字符串。在另一种描述方式中，遥控器中的NFC标签中存储的是ID(Identity Document，身份标识号)，第一设备中的NFC模块读取遥控器中的ID，将其作为第一字符串。
在另一种可能的方式中，第一设备中有RFID(Radio Frequency Identification，射频识别)模块。在RFID模块贴近具有显示屏的设备的遥控器时，RFID模块能够读取遥控器的RFID标签中的第一字符串。
需要说明的是，具有显示屏的设备的遥控设备中除了上述NFC标签和RFID标签，还可以实现为其它近距离射频识别标签。对应的，第一设备中可以设置相应的近距识别模块。比如，具有显示屏的设备的遥控设备中设置遵循A协议的射频识别标签，则第一设备中可以设置遵循A协议的射频识别模块，该射频识别模块具备读取射频识别中的信息的能力。
可选地，当预设交互操作包括拍摄预设手势，或者，预设交互操作包括拍摄预设动作时，第一内容投屏请求能够从预设应用中获取第一字符串。也即，当第一设备通过第一图像采集组件拍摄到预设手势或者拍摄到预设动作时，第一设备能够启动预设应用并从预设应用中获取第一字符串。或者，第一设备能够在预设应用处于启动状态时，从该预设应用中获取第一字符串。需要说明的是，第二设备获取第二字符串的过程与第一设备获取第一字符串的过程类似，本处不再赘述。
第二内容投屏请求：是第二设备发送给具有显示屏的设备的信息，用于请求将第二设备中播放的第二内容在具有显示屏的设备中继续播放。在一种可能的方式中，该第二内容投屏请求可以是符合固定格式的字符串，该字符串中包含关键字和字符内容。
可选地，字符内容中可以包括第二字符串，该第二字符串是第二设备从用于遥控具有显示屏的设备的遥控设备的投屏标签中读取到的信息。其中，第二设备中设置的射频模块可以和第一设备中设置的射频模块是同一类型的模块。换言之，第二设备中设置的射频模块可以和第一设备中设置的射频模块是符合同一射频协议的模块。
字符串模版：设置在具有显示屏的设备中的字符串。在一种可能的方式中，字符串模版和具有显示屏的设备对应的遥控设备中预留的字符串相同。第一设备和第二设备在正确读取遥控设备中的预留的字符串时，所述第一设备中的第一字符串、所述第二设备中的第二字符串以及字符串模版则为相同的字符串。
例如，遥控设备中预留的字符串是“abcdef1234”且字符串模版也是“abcdef1234”。当第一设备贴靠遥控设备，通过射频模块读取预留的字符串后，生成的第一字符串是“abcdef1234”，则具有显示屏的设备通过第一字符串和字符串模版相同时，能够通过验证，在具有显示屏的设备中继续播放原本在第一设备中播放的第一内容。相似的，当第二设备在射频模块正确读取遥控设备中预留的字符串时，生成的第二字符串是“abcdef1234”。具有显示屏的设备将在第二字符串和字符串模版相同时，在具有显示屏的设备中继续播放原本在第二设备中播放的第二内容。
在另一种可能的方式中，字符串模版和具有显示屏的设备对应的遥控设备中预留的字符不同，但上述两个字符串之间互相匹配。例如，遥控设备中预留的字符是“33445566abc”,字符串模版是“1122334455cba”。具有显示屏的设备中预先保存了字符串模版，并且保存了“1122334455cba”和“33445566abc”之间是绑定的关系。当具有显示屏的设备接收到第一内容投屏请求从中读取出“33445566abc”，或者，接收到第二内容投屏请求从中读取出“33445566abc”时，具有显示屏的设备可以在“33445566abc”和“1122334455cba”相匹配的场景下通过验证，在具有显示屏的设备中继续播放第一内容，或，在具有显示屏的设备中继续播放第二内容。
第一内容：显示在第一设备中的内容，该内容可以被第一设备经过跨设备的方式投屏在具有显示屏的设备中播放。本申请提供两种第一设备可选的播放方式，介绍如下。
在第一种可选的方式中，第一内容原本在第一设备中播放，在第一设备成功将第一内容投屏到具有显示屏的设备中播放后，第一内容继续在第一设备中播放。例如，当第一内容是游戏画面时，游戏画面 则可以在第一设备中继续播放，且游戏能够在第一设备中正常接收到用户的操控。又例如，当第一内容是购物应用的用户界面时，用户能够在第一设备中继续显示购物应用的用户界面，便于使用第一设备的用户继续操作并查看购物应用中显示的商品信息。
在第二种可选的方式中，第一内容原本在第一设备中播放，在第一设备成功将第一内容投屏到具有显示屏的设备中播放后，第一内容停止在第一设备中播放。在该方式中，第一设备还可以继续显示关于第一内容的操控界面。例如，当第一内容是视频时，第一设备还可以显示播放、停止、快进、快退、调整播放进度或调整音量等控件。
从第一内容所属的应用类型来说，第一内容可以是社交应用、视频类应用、阅读类应用、地图类应用、天气类应用、团购类应用、办公类应用、摄影类应用、金融类应用、出行类应用、购物类应用、游戏应用或考试学习类应用中的至少一种。
针对第二内容而言，第一内容所属的用户界面可以和第二内容所属的用户界面是相同的界面。第二内容在第二设备中的显示方式，可以和第一内容在第一设备中的显示方式相同，详情可参见上文对第一内容的介绍，此处不再赘述。
示意性的，第一内容中可以包括第一商品，第二内容中可以包括第二商品。第一内容和第二内容是属于相同购物应用的内容。
示例性地，本申请实施例所示的跨设备的内容投屏方法，可以应用在具有显示屏的设备中。可选地，具有显示屏的设备的显示屏尺寸在物理世界中是较大尺寸的设备。例如，具有显示屏的设备可以是电视、投影仪、电脑显示屏、壁画式显示屏或视频监考系统的监视器、平板电脑或笔记本电脑，本申请对此不作限定。在另一种可能的场景中，具备显示屏且配备有遥控器的设备均可实现为本申请中所示的具有显示屏的设备。
请参考图1，图1是本申请实施例提供的一种跨设备的内容投屏的实施环境的示意图。在图1中，包括具有显示屏的设备111、遥控设备112、第一设备120和第二设备130。其中，遥控设备112用于遥控具有显示屏的设备111。

在实际应用的场景中，遥控设备112中的投屏标签310若与第一设备120以及第二设备130均进行刷卡式操作，则在时间上具有先后的次序。在本申请实施例中，定义遥控设备112先与第一设备120进行刷卡式操作，再与第二设备130进行刷卡式操作。
在图3所示的第一刷卡阶段3A中，第一设备120与遥控设备112的下部触碰。设置在遥控设备112 的下部中的投屏标签310被第一设备120中的第一射频模块320读取信息，第一设备120根据读取到的信息生成第一字符串。
在图3所示的第二刷卡阶段3B中，第二设备130与遥控设备112的下部触碰。设置在遥控设备112的下部中的投屏标签310被第二设备130中的第二射频模块330读取信息，第二设备130根据读取到的信息生成第二字符串。
需要说明的是，在图3中，第一设备120中的第一射频模块320设置在设备背面的上部，第二设备130中的第二射频模块330设置在设备背面的下部。本申请实施例借此说明不同型号的设备，可以见射频模块设置在不同的位置。相应的，相同型号的设备，射频模块在设备中的位置是相同的位置。

请参考图4，图4是本申请一个示例性实施例提供的一种跨设备的内容投屏方法的流程图。该跨设备的内容投屏方法可以应用在图1所示的具有显示屏的设备中。在图4中，跨设备的内容投屏方法包括：
步骤410，接收第一设备发送的第一内容投屏请求，第一内容投屏请求是第一设备在执行预设交互操作后向具有显示屏的设备发送的请求。
在本申请中，预设交互操作可以包括扫描投屏标签、拍摄预设手势或拍摄预设动作中的一种。
当预设交互操作是扫描投屏标签时，具有显示屏的设备能够接收第一设备发送的第一内容投屏请求。其中，第一设备在扫描完投屏标签后，向该具有显示屏的设备发送第一内容投屏请求。在一种场景中，若投屏标签设置在具有显示屏的设备的遥控器中，则第一设备贴近或者触碰遥控器中设置该投屏标签的区域，第一设备将根据读取到的信息生成第一内容投屏请求，并将该第一内容投屏请求发送至具有显示屏的设备。
当预设交互操作是拍摄预设手势时，第一设备可以通过第一图像采集组件拍摄用户的手势。其中，第一图像采集组件可以是前置摄像头或者后置摄像头拍摄。预设手势包括单手手势、双手手势或手脸组合手势中的一种。单手手势是左手或者右手一只手作出的指定手势。双手手势是左右两只手互相配合作出的手势。手脸组合手势是一只手和人脸组合在一起形成的手势，或者，手脸组合手势是两只手和人脸组合在一起形成的手势。需要说明的是，本申请实施例不对预设手势具体的动作作出限定。当用户做出的手势是预设手势时，第一设备向具有显示屏的设备发送第一内容投屏请求。相应的，具有显示屏的设备接收该第一内容投屏请求。
当预设交互操作是拍摄预设动作时，第一设备可以采集包含用户的动作的多帧图像，当多帧图像中提取出的特征符合预设动作对应的特征时，第一设备可以确定拍摄到了预设动作，向具有显示屏的设备发送第一内容投屏请求。相应的，具有显示屏的设备接收该第一内容投屏请求。
可选地，具有显示屏的设备可以通过短距离无线通信的方式接收第一设备发送的第一内容投屏请求。其中，该短距离无线通信的方式可以是WiFi、蓝牙或Zigbee(紫蜂)中任意一种。第一设备发送该第一内容投屏请求时，目的在于将原本在第一设备中播放的内容在具有显示屏的设备中继续播放。其中，该第一内容是第一设备中播放的内容。该第一内容可以是第一设备中当前播放的用户界面，或者，第一内容可以是第一设备中当前处于前台运行的应用的用户界面。
步骤420，响应于第一内容投屏请求，播放第一内容，第一内容是第一设备中播放的内容。
具有显示屏的设备在接收到第一内容投屏请求后，响应于该请求，继续播放原本在第一设备中播放 的第一内容。其中，播放的内容既可以是视频，也可以是游戏画面或者手机实时显示的界面。
可选地，具有显示屏的设备可以响应于第一内容投屏请求中的第一字符串与字符串模版匹配，播放第一内容，第一字符串是第一设备从投屏标签中读取到的信息。
在本申请中，具有显示屏的设备能够从第一内容投屏请求中提取出第一字符串，将该第一字符串与字符串模版进行匹配。当第一字符串和字符串模版匹配时，具有显示屏的设备播放该第一内容。在实际应用的场景中，具有显示屏的设备既可以全屏播放该第一内容，也可以在当前具有显示屏的设备处于多屏显示模式或者分屏模式中，在其中一个显示区域中显示第一内容。
需要说明的是，第一字符串是第一设备从投屏标签中读取到的信息。该投屏标签既可以设置在具有显示屏的设备对应的遥控设备中，该投屏标签也可以单独设置成为一张射频卡，该射频识别标签还可以贴附在具有显示屏的设备的边框中。
步骤430，接收第二设备发送的第二内容投屏请求，第二内容投屏请求是第二设备在执行预设交互操作后向具有显示屏的设备发送的请求。
类似于具有显示屏的设备接收第一设备发送的第一内容投屏请求，具有显示屏的设备接收第二设备发送的第二内容投屏请求的处理流程是类似的，此处不再赘述。
可选地，第二设备既可以和第一设备是同型号的设备，也可以和第一设备是不同型号的设备。在本申请实施例中，来自同一厂商的设备可以被定义为一个型号的设备。或者，既来自同一厂商又来自同一具体型号的设备被定义为同一个型号的设备。
可选地，第二设备既可以和第一设备是同类型的设备，可以和第一设备是不同类型的设备。在本申请实施例中，设备的类型可以按照手机、平板电脑、智能手表以及笔记本电脑等分类方式对硬件的种类进行分类。
步骤440，响应于第二内容投屏请求，采用分屏模式播放第一内容和第二内容，第二内容是第二设备中播放的内容。
在本申请中，当具有显示屏的设备中已经在播放第一设备投屏的第一内容时，具有显示屏的设备对应其它设备发送来的投屏请求，能够进行响应，并通过分屏模式同时播放原先播放的第一内容，以及，新需求对应的第二内容。
可选地，响应于第二内容投屏请求中的第二字符串与字符串模版匹配，同时播放第一内容和第二内容，第二字符串是第二设备从投屏标签中读取到的信息。
由于具有显示屏的设备中已经在播放第一内容，因此，当第二字符串与字符串模版匹配时，具有显示屏的设备将根据第一内容在具有显示屏的设备中所占屏幕的区域大小，决定如何同时显示第一内容和第二内容。
在一种可能的实现方式中，当具有显示屏的设备是全屏显示第一内容时，具有显示屏的设备将采用分屏模式，重新划分出两个显示区域。其中，一个区域用于显示第一内容，另一个区域用于显示第二内容。可选地，上述两个显示区域可以分别是第一显示区域和第二显示区域。可选地，具有显示屏的设备还可以处于多屏模式中，多屏模式中的具有显示屏的设备包括2个以上的显示区域。其中2个显示区域用于显示第一内容和第二内容。
在另一种可能的实现方式中，当具有显示屏的设备在已经处于分屏模式或者多屏模式显示第一内容时，具有显示屏的设备可以在除显示第一内容之外的其它显示区域中显示第二内容。
通过上述可能的处理方式，具有显示屏的设备能够同时显示第一设备投屏的第一内容和第二设备投屏显示的第二内容。
综上所述，本实施例提供的跨设备的内容投屏方法，由于具有显示屏的设备能够先后接收第一设备和第二设备发送的内容投屏请求，并将第一设备中的第一内容继续在具有显示屏的设备中播放，且将第二设备中的第二内容继续在具有显示屏的设备中播放。其中，第一设备和第二设备是在执行预设交互操作后向具有显示屏的设备发送的投屏请求，播放相应的内容，提高了具有显示屏的设备在操作较少下同时显示多个设备投屏的内容的能力，并提高了多设备投屏的效率。
基于上一个实施例所公开的方案，具有显示屏的设备还能够预先进入分屏模式，在分屏模式中先后接收第一设备和第二设备的请求，并同时显示相应的内容。请参考如下实施例。
请参见图5，图5是本申请另一个示例性实施例提供的一种跨设备的内容投屏方法流程图。该跨设备的内容投屏方法可以应用在上述所示的具有显示屏的设备中。在图5中，该跨设备的内容投屏方法包括：
步骤511，接收分屏指令。
具有显示屏的设备能够接收分屏指令。分屏指令可以是语音指令、红外指令或者菜单控件被触发时 生成的指令。
当分屏指令是语音指令时，具有显示屏的设备可以通过语音助手等内置的软件接收该指令。比如，具有显示屏的设备可以在接收到唤醒词之后，进入语音激活状态。在具有显示屏的设备处于语音激活状态，具有显示屏的设备的麦克风可以接收到语音，并根据该语音生成语音指令。
步骤512，响应于分屏指令，进入分屏模式，具有显示屏的设备的显示屏在分屏模式中至少包括第一显示区域和第二显示区域。
具有显示屏的设备能够响应于分屏指令，进入分屏模式。在本申请中，分屏模式包括第一显示区域和第二显示区域。其中，第一显示区域用于显示第一内容，第二显示区域用于显示第二内容。
例如，用户说出唤醒词“小布小布”，具有显示屏的设备将进入语音激活状态。此时，再当用户说出进入分屏模式时，具有显示屏的设备将进入分屏模式。
又例如，用户能够通过遥控器打开具有显示屏的设备中指定的菜单，当点击菜单中的分屏按钮时，具有显示屏的设备将进入分屏模式。
步骤520，接收第一设备发送的第一内容投屏请求。
在本例中，步骤520与步骤410执行的过程相同，此处不再赘述。
步骤530，响应于第一内容投屏请求中的第一字符串与字符串模版匹配，在第一显示区域播放第一内容。
需要说明的是，当具有显示屏的设备的显示区域分为第一显示区域和第二显示区域时，第一显示区域可以是靠左侧的区域，第二显示区域可以是靠右侧的区域。
步骤540，接收第二设备发送的第二内容投屏请求。
在本例中，步骤540与步骤430执行的过程相同，此处不再赘述。
步骤550，响应于第二内容投屏请求中的第二字符串与字符串模版匹配，在第一显示区域播放第一内容的同时，在第二显示区域中播放第二内容。
在本例中，由于第一显示区域中已经在显示第一内容。因此，具有显示屏的设备将第二内容安排在第二显示区域中进行显示。
下面将通过一个实际应用的例子对上述内容进行介绍。
请参见图6，图6是基于图5所示的实施例提供的一种跨设备的内容投屏方法的应用示意图。在图6中，具有显示屏的设备是电视，第一设备是A手机，第二设备是B手机，且与具有显示屏的设备具有绑定关系的投屏标签设置在具有显示屏的设备的遥控器中。
首先，用户可以使用遥控器610或者语音的方式，控制电视620进入左右分屏的模式。示意性的，当用户通过语音的方式控制电视620时，电视620将显示提示词621“电视将进入左右分屏”。
然后，用户使用A手机630贴靠遥控器610，A手机630的射频模块从遥控器610中的投屏标签中读取到第一字符串，并将该信息包含于第一内容投屏请求，发送至电视620。相应的，电视620在验证该第一字符串和电视620中存储的字符串模版匹配时，在左侧的第一显示区域622中显示原本在A手机630中显示的内容。
随后，另一用户可以使用B手机640贴靠相同的遥控器610，B手机640的射频模块从遥控器610中的投屏标签中读取到第二字符串，且该信息包含于第二内容投屏请求，发送至电视620。相应的，电视620在验证该第二字符串和电视620中存储的字符串模版匹配时，在右侧的第二显示区域623中显示原本在B手机640中显示的内容。
综上所述，本实施例能够根据提前根据用户的语音指令或者遥控器的指示下，提前进入分屏模式。在第一设备通过具有显示屏的设备的验证后，将在其中的一个显示区域中显示第一设备中显示的第一内容，同样的，在第二设备通过具有显示屏的设备的验证后，具有显示屏的设备将在除显示第一内容的显示区域中，显示第二设备中显示的第二内容。其中，第一设备和第二设备用于和具有显示屏的设备验证的信息均是从与具有显示屏的设备有绑定关系的投屏标签中获取的。由此可见，本申请提供的具有显示屏的设备能够提供便于进入的分屏模式，且仅需一步即可将其它设备中播放的内容直接投屏到分屏模式中的一个显示区域中，随后，在已经有投屏的内容的情况下，仍然可以快速将另外的设备中的内容投屏到分屏模式中的其它显示区域中。由此可见，本申请实施例提供的方法，能够提高具有显示屏的设备同时显示多个其它设备中的投屏内容的能力。
在本申请实施例中，除了提前进入分屏模式，具有显示屏的设备还具备智能判断是否进入分屏显示第一内容和第二内容的能力。请参考如下实施例。
请参见图7，图7是本申请另一个示例性实施例提供的一种跨设备的内容投屏方法流程图。该跨设备的内容投屏方法可以应用在上述所示的具有显示屏的设备中。在图7中，该跨设备的内容投屏方法包 括：
步骤710，接收第一设备发送的第一内容投屏请求。
在本例中，步骤710与步骤410的执行过程相同，本处不再赘述。
步骤720，响应于第一内容投屏请求中的第一字符串与字符串模版匹配，全屏播放第一内容。
步骤730，接收第二设备发送的第二内容投屏请求。
在本例中，步骤730与步骤430的执行过程相同，本处不再赘述。
步骤741，响应于第二内容投屏请求，获取分屏信息。
需要说明的是，分屏信息可以包括在第二内容投屏请求中。该分屏信息用于提供给具有显示屏的设备，以令具有显示屏的设备进行判断是否进入分屏。
步骤742，响应于分屏信息符合预设条件，在第一显示区域中播放第一内容，并在第二显示区域中播放第二内容，具有显示屏的设备的显示屏在分屏模式中至少包括第一显示区域和第二显示区域。
在本例中，具有显示屏的设备在分屏信息符合预设条件时，在第一显示区域中播放第一内容，在第二显示区域中播放第二内容。其中，第一显示区域和第二显示区域是互不重合的显示区域。
需要说明的是，本申请能够根据分屏信息的具体形式，而提供相应的自动进入分屏模式的方案，现介绍如下。
(1)，分屏信息是涉及分屏的设备信息，具体是体现第一设备成功投屏的时刻与第二设备成功投屏的时刻。
步骤a1，响应于第二内容投屏请求，获取第一设备的投屏时刻和第二设备的投屏时刻之间的参考时长。
步骤a2，响应于参考时长小于第一阈值，在第一显示区域中播放第一内容，并在第二显示区域中播放第二内容。
在本例中，第一设备的投屏时刻用于指示第二内容成功投屏在具有显示屏的设备中的时刻，第二设备的投屏时刻用于指示第三内容成功投屏在具有显示屏的设备中的时刻。
示意性的，具有显示屏的设备将根据第一设备成功在具有显示屏的设备上的投屏时刻，以及，第二设备成功在具有显示屏的设备上的投屏时刻，计算两个投屏时刻之间的时长，也即计算该参考时长。该参考时长可以反映第一设备和第二设备之间投屏的关联性，若该参考时长较短，则说明第一设备在具有显示屏的设备上的进行投屏，与，第二设备在具有显示屏的设备上进行投屏这两个事件具有较强的相关性。因此，基于该设计思想，本申请在该参考时长小于第一阈值时，在第一显示区域中播放第一内容，并在第二显示区域中播放第二内容。经过上述处理，具有显示屏的设备能够较为智能地同时播放第一设备投屏的第一内容和第二设备投屏的第二内容。
相应的，当参考时长大于或者等于第一阈值时，具有显示屏的设备中原本显示的第一内容，将被第二设备中的第二内容所替换显示。
在一个实际应用的例子中。例如参考时长是37秒，第一阈值是120秒。在该情况中，参考时长小于第一阈值。因此，具有显示屏的设备在第一显示区域中播放第一内容，并在第二显示区域中播放第二内容。
在另一个例子中，参考时长是560秒。在该情况中，参考时长大于第一阈值。因此，原本在具有显示屏的设备中显示的第一内容，将被第二内容所替换，具有显示屏的设备将显示第二内容。
(2)，分屏信息是涉及分屏的设备信息，具体是第二设备的历史投屏信息。
步骤b1，响应于第二内容投屏请求，获取第二设备的历史投屏信息，历史投屏信息包括第二设备成功向具有显示屏的设备投屏的投屏次数或投屏累计时长中至少一种信息。
步骤b21，响应于投屏次数大于或等于第二阈值，在第一显示区域中播放第一内容，并在第二显示区域中播放第二内容。
步骤b22，响应于投屏累计时长大于或等于第三阈值，在第一显示区域中播放第一内容，并在第二显示区域中播放第二内容。
需要说明的是，具有显示屏的设备在执行完成步骤b1后，既可以执行步骤b21，也可以执行步骤b22。
在本例中，具有显示屏的设备能够根据第二设备的投屏累计时长决定，是否分屏同时显示第一内容和第二内容。若第二设备的投屏累积时长足够长，则说明第二设备与具有显示屏的设备在投屏方面有较强的相关性。在此情况下，具有显示屏的设备将分屏为两个互不重合的显示区域，也即第一显示区域和第二显示区域。然后，具有显示屏的设备分别在第一显示区域中显示第一内容，在第二显示区域中显示第二内容。
在本例中，具有显示屏的设备还能够根据第二设备历史上成功在具有显示屏的设备上进行投屏的投 屏次数，决定是否分屏显示第一内容和第二内容。当第二设备在具有显示屏的设备上的投屏次数大于或者等于第二阈值时，说明第二设备与具有显示屏的设备在投屏方面有较强的相关性，具有显示屏的设备将分屏后同时显示第一内容和第二内容。
相对的，当历史投屏信息指示第二设备与具有显示屏的设备在投屏方面的相关性不强时，具有显示屏的设备将在显示屏中显示对话框。该对话框用于提醒用户选择具有显示屏的设备是通过分屏显示第一内容和第二内容。或者，该对话框用于提醒用户选择具有显示屏的设备停止显示第一内容并在原本显示第一内容的显示区域显示第二内容。
(3)，分屏信息是涉及分屏的内容，具体是第一内容的图像信息以及第二内容的图像信息。
步骤c1，响应于第二内容投屏请求，根据预设策略获取第一内容中的第一图像信息，并根据预设策略获取第二内容中的第二图像信息。
步骤c2，响应于第一图像信息和第二图像信息之间的相似度大于或等于第四阈值，在第一显示区域中播放第一内容，并在第二显示区域中播放第二内容。
在本例中，具有显示屏的设备能够自主对第一内容和第二内容进行图像识别。在具体的应用方式中，具有显示屏的设备能够根据第二内容投屏请求获取到第二内容，并获取第二内容中的第二关键帧。其中，第二关键帧是在指定时刻获取的图像帧。具有显示屏的设备在同样的指定时刻下，获取到第一内容中的图像帧，该第一内容中的图像帧是第一关键帧。具有显示屏的设备能够提取第一关键帧中的图像特征，并能够提取第二关键帧中的图像特征。当第一关键帧中的图像特征与第二关键帧中的图像特征之间的相似度大于或者等于第四阈值时，说明第一内容和第二内容有较大可能属于同一个应用，或者，说明第一内容和第二内容显示相应的对象。例如，第一内容和第二内容中显示有相同的人物或者显示有相同的物品。
由于第一内容和第二内容中显示的内容在相似度时，较大可能是用户希望同时投屏在具有显示屏的设备中同时观看进行比较。因此，在该场景中，具有显示屏的设备将进入分屏状态，并同时显示第一内容和第二内容。
(4)，分屏信息是涉及分屏的内容，具体是第一内容的内容标识和第二内容的内容标识。
步骤d1，响应于第二内容投屏请求，获取第一内容对应的第一内容标识和第二内容对应的第二内容标识。
步骤d2，响应于第一内容标识和第二内容标识匹配，在第一显示区域中播放第一内容，并在第二显示区域中播放第二内容。
在本例中，内容标识既可以指示内容对应的应用的标识，也可以指示内容对应的应用所属的类别，还可以指示内容中的对象类型。
(1)内容标识指示内容对应的应用。例如，第一内容标识和第二内容标识均用于指示内容对应的应用。当第一内容标识是A应用的标识，且第二内容该标识是A应用的标识时，具有显示屏的设备确定第一内容标识和第二内容标识匹配，在第一显示区域中播放第一内容，同时在第二显示区域中播放第二内容。相对的，当第一内容标识指示的应用和第二内容标识指示的应用是不同的应用时，具有显示屏的设备可以停止显示第一内容，并在原本显示第一内容的显示区域中显示第二内容。
(2)内容标识指示内容对应的应用的类别。例如，第一内容标识和第二内容标识分别用于指示第一内容对应的应用的类别，和，第二内容对应的应用的类别。例如，当第一内容标识是游戏类应用标识且第二内容标识是视频应用标识，则第一内容标识和第二内容标识不匹配。当第一内容标识是游戏类应用标识且第二内容标识也是游戏类应用标识，则第一内容标识和第二内容标识匹配。
(3)内容标识指示内容中的对象，该对象可以是人物，也可以是其它的物品。例如，第一内容标识指示的是人物杰克，第二内容标识指示的是人物布朗，则第一内容标识和第二内容标识不匹配。若第一内容标识指示的是人物布朗，且第二内容标识指的也是人物布朗，则第一内容标识和第二内容标识匹配。
在本申请实施例中，上述四种场景用于指示具有显示屏的设备自动识别到需要进入分屏模式，在不同的显示区域中分别显示第一内容以及第二内容。而具有显示屏的设备还能够提供一个供用户选择的控件，供用户自动选择是否进入分屏模式，从而分别在分屏模式中的第一显示区域中显示第一内容，并在第二显示区域中显示第二内容。请参见如下用户手动选择的方案。
步骤e1，响应于第二内容投屏请求，显示分屏按钮。
步骤e2，响应于分屏按钮被触发，在第一显示区域中播放第一内容，并在第二显示区域中播放第二内容。
在本申请实施例中，具有显示屏的设备能够在接收到第二设备的内容投屏请求时，显示分屏按钮。示意性的，该分屏按钮可以显示在具有显示屏的设备的显示屏中。用户能够使用遥控设备触发该分屏按 钮，当该分屏按钮被触发时，具有显示屏的设备将在第一显示区域中播放第一内容，并在第二显示区域中播放第二内容。
可选地，具有显示屏的设备还能够显示关闭控件，当用户触发关闭控件时，具有显示屏的设备将停止显示分屏按钮。
综上所述，具有显示屏的设备能够先接收第一设备的第一内容投屏请求，并在该请求符合预设条件的时候全屏显示第一设备对应的第一内容。随后，具有显示屏的设备在通过多种方式自动识别第二内容的重要程度或者投屏第二内容的第二设备的安全性，在第二内容较为重要或者第二设备相对具有显示屏的设备较为安全时，具有显示屏的设备自动进入分屏模式，同时显示第一内容和第二内容，提高了具有显示屏的设备的智能化，减少了用户为第一内容和第二内容同时显示所需的操作，提高了多个设备同时投屏在一个设备上的便利性。
可选地，具有显示屏的设备能够根据第一内容和第二内容开始投屏时刻之间的参考时长的时间长度，确定是否自动进行分屏显示。当第一内容和第二内容在具有显示屏的设备上开始投屏的时刻相距时间不长，则说明两个内容之间的相关性足够高，具有显示屏的设备将自动进入分屏状态，并同时显示第一内容和第二内容，实现了具有显示屏的设备从投屏行为上智能确定是否同时显示第一内容和第二内容的能力。
可选地，具有显示屏的设备能够第二设备的历史投屏信息确认第二设备与具有显示屏的设备之间的亲密程度，当具有显示屏的设备和第二设备之间经常连接，具有较为亲密的关系，则具有显示屏的设备将自动进入分屏状态，并同时显示第一内容和第二内容，提高了具有显示屏的设备从第二设备的历史投屏情况智能判断是否同时显示第一内容和第二内容的能力。
可选地，具有显示屏的设备还能够根据第一内容与第二内容在图像上的相似度，决定是否自动进入分屏状态，从而同时显示第一内容和第二内容。当第一内容和第二内容在图像上的相似度较大时，说明第一内容和第二内容有较强的关联性，用户较大可能会同时查看两者并进行比较。因此，具有显示屏的设备在该场景中，能够自动进入分屏状态，从而同时显示第一内容和第二内容。
可选地，具有显示屏的设备还能够根据第一内容标识和第二内容标识是否匹配来确定是否进入分屏状态，当上述两个内容标识匹配时，说明第一内容和第二内容需要在能够同时查看的状态下进行显示。因此，在该场景中，具有显示屏的设备自动进入分屏状态并同时第一内容和第二内容，实现了多个设备显示的内容是相关的情况下，具有显示屏的设备自动同时显示第一内容和第二内容。
本申请实施例除了上述能够自动识别需要分屏的场景外，还能够应用在移动设备进行作答，且监考设备对移动设备进行监控的场景中。在该场景中，具有显示屏的设备是监控设备，第一设备和第二设备均为显示考试试卷且供考生使用的设备。关于该应用场景的介绍，请参考图8所示的内容。
请参考图8，图8是本申请实施例提供的一种应用于监考场景的跨设备的内容投屏方法流程图。图8中涉及的方法可以由图1所示的具有显示屏的设备实现，详情如下：
步骤811，启动具有显示屏的设备，具有显示屏的设备是考场的监控设备。
在本例中，具有显示屏的设备是考场中的监控设备，监考官可以在考试的过程中通过具有显示屏的设备了解考生使用的考试设备中显示的内容。
需要说明的是，第一设备和第二设备均为考试设备。本申请中可以包括一个第一设备和若干个第二设备。其中，第一设备是第一个投屏在具有显示屏的设备中投屏的设备，第二设备是在第一设备完成投屏之后在具有显示屏的设备中投屏的设备。
在该场景中，监控设备可以配套提供一个射频卡片，射频卡片是投屏标签。第一设备和第二设备等可以靠近该射频卡片，从而从射频卡片中读取信息，生成第一字符串或第二字符串。
需要说明的是，在一种可能的方式中，该射频卡片是每个考场配备一个，在该考场进行考试的考生均使用自己的考试设备扫描该射频卡片。
在另一种可能的方式中，该射频卡片可以在每个考生的座位上设置一个射频卡片。
步骤812，接收第一设备发送的第一内容投屏请求。
在本例中，第一设备在从射频卡片中读取信息，并生成第二字符串后，会将该第二字符串置于第一内容投屏请求中，并向第一设备发送该第一内容投屏请求。
相应的，该具有显示屏的设备接收第一设备发送的第一内容投屏请求。
步骤813，响应于第一内容投屏请求中的第一字符串与字符串模版匹配，播放第一内容。
具有显示屏的设备在接收到第一内容投屏请求之后，可以从该内容投屏请求中，读取出第一字符串，在第一字符串与字符串模版匹配时，播放第一内容。
其中，该第一内容是第一设备屏幕中显示的内容。也即，第一设备中实时显示的内容将同步投屏到 具有显示屏的设备中显示。
步骤814，接收第二设备发送的第二内容投屏请求。
步骤815，响应于第二内容投屏请求中的第二字符串与字符串模版匹配，同时播放第一内容和第二内容。
类似于第一设备将第一内容投屏到具有显示屏的设备中显示，第二设备将重复与第一设备一样的操作，也在具有显示屏的设备中投屏。在本申请实施例中，由于在一个考场中的考生数量通常有几个或者几十个。因此，一个具有显示屏的设备可以对应一个第一设备和若干个第二设备。
在上述对应设计中，考虑到具有显示屏的设备的屏幕尺寸，第二设备的数量可以是7个、9个、15个或者19等数量。
在第二设备成功将第二内容投屏到具有显示屏的设备上后，具有显示屏的设备将同时显示第一内容和第二内容。在该场景中，考生均使用第一设备或者第二设备进行考试答题。由于电子设备的特殊性，监考官同时监考多个考生使用的考试设备也较为困难。在本申请提供的方法中，监考官能够在具有显示屏的设备中同时看到第一内容和若干个第二内容，以实时查看考生所看的答题界面。
步骤821，响应于第一内容和/或第二内容中包括异常图像，记录异常图像和异常图像显示的时刻。
在本例中，具有显示屏的设备能够对第一内容和/或第二内容中的图像进行图像识别。在一种可能的方式中，具有显示屏的设备能够逐帧进行图像识别。在另一种可能的方式中，具有显示屏的设备能够每隔N帧，对同一个内容中的图像进行一次识别。例如，具有显示屏的设备对第一内容中的图像帧进行图像识别，以30帧图像为一组图像。具有显示屏的设备能够对一组图像中的第一张图像帧进行图像识别。
其中，具有显示屏的设备中可以预设属于正常的图像模版。具有显示屏的设备将从第一内容或者第二内容中获取到的图像帧，与，图像模版进行比较。当相似度高于预设阈值时，说明图像帧属于正常图像；当相似度等于或者低于预设阈值时，说明图像帧属于异常图像。
在具有显示屏的设备识别出异常图像时，记录出现异常图像的设备并记录异常图像显示的时刻。
在另一种识别异常图像的方式中，异常图像所属的应用不属于白名单应用列表。在考试场景中，具有显示屏的设备中可以维护一个白名单应用列表，与本场考试相关的应用标识将被列入该白名单应用列表中。当考生使用自己的考试设备使用上述与本场考试相关的应用时，第一内容或者第二内容所属的应用的标识均属于白名单应用列表。若考生使用其他的应用，则会被具有显示屏的设备第一时间抓取到。需要说明的是，具有显示屏的设备获取的第一内容或者第二内容中的每个图像帧均对应有所属的应用的标识。
例如，属于白名单应用列表的应用包括A考试应用和B计算器应用。当具有显示屏的设备识别到第一内容中存在一个图像帧所属的应用既不是A考试应用，也不是B计算器应用，则判断第一内容是包括异常图像的内容。
可选地，具有显示屏的设备除了执行步骤821，还可以继续执行步骤822。
步骤822，将包括异常图像的内容突出显示，突出显示包括高亮、显示预设标记或显示预设文本中至少一种。
在本申请实施例中，具有显示屏的设备为了提醒监考官出现异常的情况，可以将包括异常图像的内容突出显示。例如，第一设备中的第一内容包括异常图像，具有显示屏的设备在显示第一内容时，突出显示该第一内容。可选的突出显示的方式，包括但不限于高亮显示区域，或者在第一内容上附加一个预设标记，或者在第一内容上附加显示预设文本。本申请实施例不对具体的突出显示的方式进行限定。
步骤830，向出现异常图像的设备发送锁定信号，锁定信号用于指示出现异常图像的设备停止接收输入信号。
在本例中，具有显示屏的设备还能够向出现异常图像的设备发送锁定信号，使得出现异常图像的设备在锁定信号的作用下，不能再接收输入信号。通过该设计，使得具有显示屏的设备能够在监考的其它设备出现异常时，直接锁定相应的考试设备，从而实现严格处理考试异常现象，实现了用户使用自身日常使用的设备进行无纸化考试，且能够接收到严格监考的效果。
综上所述，本申请实施例提供的方法能够应用在无纸化考试的监考场景中，能够实现考生使用自己日常使用的移动设备来参加考试的效果，并且能够实现较为严格监考效果，降低了建造无纸化考场的成本且保证了考试严格的监考效果。
在本申请实施例中，具有显示屏的设备除了能够同时显示第一内容和第二内容，具有显示屏的设备还能够对其显示的内容进行控制，详情可参考图9所示的实施例。
请参考图9，图9是本申请实施例提供的一种跨设备的内容投屏的方法流程图。该方法可以应用在 如图1所示的具有显示屏的设备中。在图9中，方法包括：
步骤911，接收第一设备发送的第一内容投屏请求。
步骤912，响应于第一内容投屏请求中的第一字符串与字符串模版匹配，播放第一内容。
步骤913，接收第二设备发送的第二内容投屏请求。
步骤914，响应于第二内容投屏请求中的第二字符串与字符串模版匹配，同时播放第一内容和第二内容。
在本申请实施例中，上述步骤911至步骤914的执行过程可以参考步骤410至步骤440的执行过程，此处不再赘述。
步骤921，接收局部区域信息。
其中，局部区域信息用于指示第一设备中的一个局部区域的信息，或，第二设备中的一个局部区域的信息。
步骤922，响应于局部区域信息，将局部区域信息对应的区域放大k倍。
其中，k大于1。具有显示屏的设备能够通过放大局部区域信息对应的区域，令用户更为容易地观察到自己较为关注的区域。
步骤923，在局部区域信息对应的显示区域中，显示放大k倍后的局部区域信息对应的区域。
在本申请实施例中，具有显示屏的设备能够在用户的控制下对第一内容中的局部区域进行放大显示。一种可能的方式中，局部区域信息是第一设备发送至具有显示屏的设备的信息。另一种可能的方式中，局部区域信息是具有显示屏的设备对应的遥控设备发送的信息。
当具有显示屏的设备获取到局部区域信息时，具有显示屏的设备将确定该局部区域信息对应的区域。并且，将原本显示在该区域中的图像放大k倍显示。若局部区域信息对应的显示区域是第一显示区域，则具有显示屏的设备在第一显示区域显示放大k倍后的局部区域信息对应的区域。若局部区域信息对应的显示区域是第二显示区域，则具有显示屏的设备在第二显示区域显示放大k倍后的局部区域信息对应的区域。
请参见图10，图10是基于图9所示实施例提供的一种具有显示屏的设备的显示示意图。在图10中，具有显示屏的设备111中包括第一显示区域210和第二显示区域220。在第一显示区域210中包括第一局部显示区域211。其中，局部区域信息用于指示第一局部显示区域211。随后，具有显示屏的设备111在第二局部显示区域212中显示放大k倍后的图像。
例如，局部显示区域211中原本显示的第一内容中的小地图，则具有显示屏的设备可以将该区域内的小地图进一步放大显示，使得用户能够对于关心的内容能够更详细看到细节。
可选地，具有显示屏的设备能够将第二内容中，相对应的局部区域放大k倍显示。例如，第二内容和第一内容相同，同样显示有游戏界面，则具有显示屏的设备具备将第一内容中的小地图和第一设备中的小地图置于贴靠在一起的区域显示，便于用户直接从具有显示屏的设备中比较第一内容中和第二内容中被确定的部分。
步骤931，对第一内容进行图像识别，得到与预设关键字匹配的第一文本。
步骤932，对第二内容进行图像识别，得到与预设关键字匹配的第二文本。
步骤933，将第一文本和第二文本进行对比显示。
在本申请中，具有显示屏的设备能够对第一内容和第二内容进行图像识别，获取其中的文本信息。当其中的文本信息均与预设关键匹配时，具有显示屏的设备将第一文本和第二文本进行对比在一起显示。其中，预设关键字是具有显示屏的设备中设置的关键字。在一种显示的方式中，第一文本在第一显示区域中显示，第二文本在第二显示区域中显示，第一文本和第二文本之间的距离小于第五阈值。可选地，第一文本和第二文本在对比区域中显示，对比区域是横跨第一显示区域和第二显示区域的区域。
示意性的，第一文本和第二文本的划分算法相同。比如，若第一文本是一句话，则第二文本同样是一句话。若第一文本是一段话，则第二文本同样是一段话。
例如，若第一内容是针对商品A在购物应用S2中的购物页面，第二内容是针对商品A在购物应用S3中的购物页面。其中，预设关键字是“实际价格”。具有显示屏的设备在第一内容中提取到的第一文本是“实际价格：224元”，同时第一设备在第二内容中提取到的第二文本是“实际价格：206元”。随后，具有显示屏的设备在第一显示区域与第二显示区域交界的位置，同时显示该第一文本和第二文本，以便用户直接比较到最关心的信息。
请参见图11，图11是基于图9所示实施例提供的一种具有显示屏的设备的显示界面的示意图。在图11中，具有显示屏的设备111的显示区域包括第一显示区域210以及第二显示区域220。在第一显示区域210中包括第一对比显示区域213，在第二显示区域220中包括第二对比显示区域221。具有显示屏的设备111可以在第一对比显示区域213中显示第一内容中被提取到的第一文本11A，具有显示屏 的设备111还可以在第二对比显示区域221中显示第二内容中被提取到的第二文本11B，以便用户能够直观的比较第一内容和第二内容中，用户比较关心的部分。
需要说明的是，图11中显示的第一内容和第二内容均是商品篮球，被提取的信息包括价格、销量和所属的店铺名称。可选地，具有显示屏的设备还可以将价格较低的文本进行突出显示。
步骤941，接收第一设备发送的第一商品提取命令。
其中，第一商品提取命令用于提取第一内容中指定的商品。
步骤942，响应于第一商品提取命令，提取并存储对应的第一商品。
步骤943，接收第二设备发送的第二商品提取命令。
其中，第二商品提取命令用于提取第二内容中指定的商品。
步骤944，响应于第二商品提取命令，提取并存储对应的第二商品。
步骤945，接收汇总指令，将存储的第一商品和第二商品发送至发出汇总指令的设备。
其中，发出汇总指令的设备是第一设备或第二设备。
在本申请实施例中，第一设备和第二设备能够分别从已经投屏到具有显示屏的设备上的内容中，选定需要提取的商品。其中，商品可以是文本、图像或链接。
可选地，第一商品和第二商品是相同类型的商品，该类型是目标类型。
示意性的，本申请除了能够提取商品，还能够提取景点、商品、饭店、商场、明星、电影名、演唱会或页面等对象。
需要说明的是，在具有显示屏的设备提取并存储相应的对象之后，还可以根据对象类型的不同执行相应的策略。例如，当目标类型是景点时，具有显示屏的设备自动生成旅行路线，并向第一设备或者第二设备发送该旅行路线。
又例如，当目标类型是商品时，具有显示屏的设备自动比较已经被提取出的商品中，相同商品中的最低价商品，并向第一设备或者第二设备发送加购指令，该加购指令用于指示将该商品添加到购物应用中的购物车中。
综上所述，在本申请实施例中，具有显示屏的设备能够将已经被投屏显示的第一内容和第二内容中需要同时被放大的内容进行放大，实现了有效显示用户关注的区域的能力。
可选地，具有显示屏的设备还能够对第一内容以及第二内容进行图像识别，在其中包含有与预设关键字匹配的文本贴靠在一起显示，降低了用户同时比较两个内容中重点关注的信息的难度，提高了在具有显示屏的设备中比较多个其它设备中显示的内容的效率。
可选地，具有显示屏的设备还能够分别在第一设备和第二设备的控制下，分别提取并存储相应的对象，在第一设备和第二设备均可以在各自的设备中选定对象，最终被选定的对象可以汇总的其中一个设备中，实现了多个设备可以在具有显示屏的设备显示参考的场景下，完成共同选择对象的能力。
