应理解，如图6所示，应用程序层中可以包括绘制层和视图层(或者，控件层)，绘制层和视图层可以实现source端的界面显示。视图层可以为开发者提供搭建界面的界面元素，例如TextView或者ImageView，开发者通过TextView提供的接口(例如，setText)可以设置文字样式、文字大小、文字粗细等。内容提取模块602可以直接在视图层完成对界面元素的提取。或者，视图层所提供的界面元素可以在绘制层转化为drawText和drawImage等指令，内容提取模块602也可以在绘制层中通过drawText和drawImage等指令提取出界面元素。
方式三
应用的开发者可以自定义内容，例如开发者可以为界面上包括多个界面元素设置<key，value>这种格式内容，从而source端设备可以对具备这样格式内容的界面元素进行 提取。
数据传输模块604可以将source端显示界面的场景名称(例如，music、chat等场景)以及被标记的界面元素的信息(包括界面元素的标签信息以及通过内容提取模块602提取出的界面元素)发送给sink端设备的内容解析模块606。
一个实施例中，source端设备可以向sink端设备发送BLE数据包，该BLE数据包中可以携带界面元素以及界面元素的标签信息。BLE数据包中包括协议数据单元(protocol data unit，PDU)，该界面元素以及界面元素的标签信息可以携带在PDU中的服务数据(service data)字段中，或者，也可以携带在PDU中的厂商特定数据(manufacturer specific data)字段中。例如，服务数据字段的负荷(payload)中可以包括多个比特位，其中，多个比特位中包括可扩展的比特位。source端设备和sink端设备可以约定某个可扩展的比特位的内容。
例如，对于图形类界面元素(ImageView)，source端设备可以通过图像编码技术对该图形类界面元素进行图像编码，并将图像编码后的数据携带在第一比特位(第一比特位可以包括一个或者多个比特位)上；同时，source端设备可以对该图形类界面元素的标签信息进行编码。以该图形类界面元素为表1中的界面元素301为例，该界面元素301的标签信息可以为名称“封面图片”。Source端设备可以通过GBK、ISO8859-1或者Unicode(例如，UTF-8、UTF-16)等编码方式对该标签信息进行编码，并将编码后的数据携带在第二比特位(第二比特位可以包括一个或者多个比特位)上；source端设备可以将第一比特位和第二比特位进行关联。sink端设备在接收到该BLE数据包后，可以通过图像解码技术对第一比特位上的数据进行解码从而获得界面元素301；同时，sink端设备还可以对第二比特位上的信息进行解码从而获得该界面元素301的标签信息“封面图片”。
又例如，对于文本类界面元素(TextView)，source端设备可以通过GBK、ISO8859-1或者Unicode(例如，UTF-8、UTF-16)等编码方式对该文本类界面元素进行编码，并将图像编码后的数据携带在第三比特位(第三比特位可以包括一个或者多个比特位)上；同时，source端设备可以对该文本类界面元素的标签信息进行编码。以该文本类界面元素为表1中的界面元素303为例，该界面元素303的标签信息可以为名称“歌手”。Source端设备可以通过GBK、ISO8859-1或者Unicode(例如，UTF-8、UTF-16)等编码方式对该标签信息进行编码，并将编码后的数据携带在第四比特位(第四比特位可以包括一个或者多个比特位)上；source端设备可以将第三比特位和第四比特位进行关联。sink端设备在接收到该BLE数据包后，可以通过相应的解码技术对第三比特位上的数据进行解码从而获得界面元素303；同时，sink端设备还可以对第四比特位上的信息进行解码从而获得该界面元素303的标签信息“歌手”。
应理解，对于音乐播放进度条以及开关控件等不属于图形类界面元素且不属于文本类界面元素的界面元素，source端设备可以将这些界面元素以及开关控件转化为字符串，从而source端设备也可以采用GBK、ISO8859-1或者Unicode(例如，UTF-8、UTF-16)等编码方式对这些界面元素以及其标签信息进行编码。
一个实施例中，source端设备除了向sink端设备发送界面元素以及界面元素的标签信息以外，还可以向sink端设备发送界面元素对应的场景信息。示例性的，对于图3所示的GUI，手机还可以向笔记本电脑发送的BLE数据包中携带场景信息“音乐”。Source端在 BLE数据包中携带场景信息的实现过程可以参考source端设备在BLE数据包中携带标签信息的过程，此处不再赘述。
一个实施例中，该标签信息可以是名称，也可以是ID。例如，对于界面元素301，source端设备和sink端设备可以约定ID为1的界面元素对应的名称为“封面图片”，可以约定ID为2的界面元素对应的名称为“歌曲名”等。

Sink端设备的内容解析(view content parser)模块606用于在接收到source端设备的数据传输模块604发送的数据包后，对接收到的数据包进行解析，从而获得一个或者多个界面元素以及其标签信息。一个实施例中，sink端设备还可以获取当前的场景信息。
Sink端设备中保存有不同场景下界面元素显示区域以及界面元素的标签信息的对应关系。图8和图9分别输出了音乐场景下以及聊天场景下界面元素区域分布的示意图。
示例性的，图8示出了一种sink端设备保存的音乐场景的界面元素区域分布的示意图。区域801中可以显示封面图片，区域802中可以显示歌曲名称、区域803中可以显示歌手、区域804中可以显示当前正在播放的歌词、区域805中可以显示点赞控件、区域806中可以显示播放上一首歌曲的控件、区域807中可以显示暂停/播放控件以及区域808中可以显示播放下一首歌曲的控件。
内容解析模块可以根据解析出的每一个界面元素以及每一个界面元素对应的标签信息，将界面元素放入指定的区域。示例性的，当sink端设备解析出界面元素301且该界面元素301标签信息中的名称为封面图片，则sink端设备可以将界面元素301放入区域801；当sink端设备解析出界面元素302且该界面元素302标签信息中的名称为歌曲名称，则sink端设备可以将界面元素302放入区域802。
示例性的，图9示出了sink端设备保存的聊天场景的界面元素区域分布的示意图。区域901中可以显示应用程序的名称；区域902中可以显示第一组聊天记录，其中区域902中还可以包括多个子区域，例如区域9021中可以显示联系人的头像、区域9022中可以显示联系人的名称、区域9023中可以显示用户与联系人最近的一次聊天内容以及区域9024中可以显示用户与联系人最近的一次聊天的实现信息。以此类推，区域903-905中可以显示第二组聊天记录、第三组聊天记录以及第四组聊天记录。
内容解析模块可以根据解析出的每一个界面元素以及每一个界面元素对应的标签信 息，将每一个界面元素放入指定的区域。示例性的，sink端设备解析出界面元素401-404为第一组聊天记录中的界面元素。若界面元素401标签信息中的名称为联系人名称，则sink端设备可以将界面元素401放入区域9021；若界面元素402标签信息中的名称为联系人的名称，则sink端设备可以将界面元素402放入区域9022；若界面元素403的标签信息中的名称为最近一次的聊天内容，那么sink端设备可以将界面元素403放入区域9023中；若界面元素404的标签信息中的名称为最近一次的聊天的时间信息，那么sink端设备可以将界面元素404放入区域9024中。同样的，sink端设备可以将其他界面元素分别放入区域902-904中。
动作翻译模块607用于在sink端设备检测到触控事件(例如，对于某个控件的点击事件)时，向source端设备的远端动作接收模块605发送相应的事件以及该事件对应的界面元素的标签信息。
一个实施例中，当sink端的动作翻译模块607检测到用户对第一界面元素的点击事件后，sink端设备可以向source端设备发送BLE数据包，该BLE数据包中包括事件的类型信息以及第一界面元素的标签信息。BLE数据包中包括协议数据单元，该界面元素以及界面元素的标签信息可以携带在PDU中的服务数据字段中，或者，也可以携带在PDU中的厂商特定数据字段中。例如，服务数据字段的负荷中可以包括多个比特位，其中，多个比特位中包括可扩展的比特位。source端设备和sink端设备可以约定某个可扩展的比特位的内容。示例性的，以sink端设备为笔记本电脑为例，当某些可扩展的比特位为00时表示该事件的类型为选中第一界面元素；当某些可扩展的比特位为01时表示该事件的类型为选中第一界面元素后右键点击。又例如，sink端设备可以通过GBK、ISO8859-1或者Unicode(例如，UTF-8、UTF-16)等编码方式对第一界面元素对应的标签信息进行编码并将编码后的数据携带在一个或者多个可扩展的比特位上。Source端设备在对BLE数据包进行解析后就可以获知事件的类型以及对应的界面元素的标签信息，从而获知sink端设备检测到在第一界面元素上的相应事件。
远端动作接收模块605在接收到动作翻译模块607发送的事件后，可以将接收到的信息发送给动作调度模块603。动作调度模块603可以根据界面元素的标签信息查找到相应的界面元素，并通过事件类型确定用户在sink端设备上对该界面元素具体的操作。从而动作调度模块603可以当前的显示界面上的界面元素进行更新。
对示例性的，如图3中的(b)所示，当笔记本电脑检测到用户对暂停/播放控件的输入时，笔记本电脑可以向手机发送事件类型(点击事件)以及界面元素313的标签信息。响应于接收到上述信息，手机可以确定用户在笔记本电脑上针对该暂停/播放控件进行点击操作，从而手机可以对当前正在播放的音乐进行暂停。手机将界面元素313从播放状态更新为暂停状态，同时，手机停止向笔记本电脑发送歌曲对应的音频内容且手机还可以向笔记本电脑发送更新后的界面元素313以及界面元素313的标签信息，从而笔记本电脑可以显示更新后的界面元素313。
一个实施例中，若一个或者多个界面元素中包括第二界面元素且第二界面元素的状态是实时更新的，那么第一电子设备在向第二电子设备发送一个或者多个界面元素以及其标签信息后，第一电子设备可以在检测到第二界面元素的状态更新后，可以实时向第二电子设备发送更新后的第二界面元素以及其标签信息。以图3中的(b)所示的界面元素305 为例，当前正在播放的歌词是实时更新的，例如在第00:12-00-15播放的是歌词“ExxxxxxxF”，在00:16-00：18播放的是歌词“GxxxxxxxH”。那么在歌曲播放到00:16这一刻，手机可以向笔记本电脑发送更新后的界面元素305(“GxxxxxxxH”)以及其标签信息。这样笔记本电脑在接收到更新后的界面元素305以及其标签信息后，可以对当前正在播放的歌词的内容进行更新。
一个实施例中，对于图4中的(d)所示，当笔记本电脑检测到用户在文本输入框416中检测到用户输入了文本内容“好”的操作时，笔记本电脑可以向手机发送该文本内容以及文本输入框的标签信息。示例性的，笔记本电脑可以向手机发送BLE数据包，该文本内容以及文本输入框的标签信息可以携带在PDU中的服务数据字段中。笔记本电脑可以采用GBK、ISO8859-1或者Unicode(例如，UTF-8、UTF-16)等编码方式对文本内容以及文本输入框的标签信息进行编码，并将编码后的数据携带在服务数据字段的可扩展比特位上。手机在接收到该BLE数据包后，可以对可扩展比特位上的数据进行解码从而获得文本内容以及文本输入框的标签信息，从而手机可以将该文本内容放入手机的文本输入框422中显示。
当笔记本电脑检测到用户点击发送控件418的操作时，笔记本电脑可以向手机发送相应的事件类型以及控件418的标签信息。具体的发送过程可以参考上述实施例中的描述，此处不再赘述。手机在接收到事件类型以及控件418的标签信息后，可以确定笔记本电脑检测到用户点击了发送控件。从而手机可以完成对文本输入框422中的内容的发送。
应理解，本申请实施例中，文本输入框416可以是笔记本电脑绘制的。笔记本电脑和手机可以提前约定文本输入框416、语音控件417以及发送控件418的标签信息。这样手机在接收到笔记本电脑发送的内容后就可以获知用户在笔记本电脑上进行的操作。
