在一些实施例中，第一设备上安装有运动健康应用，用户可以通过该应用的用户界面与穿戴设备建立无线连接，也即是，将穿戴设备添加为第一设备的附属设备。示例性，可参见图7A至图7D的相关描述，此处不再赘述。
S102:穿戴设备将用户数据发送至第一设备。
其中，用户数据可以包括用户的名称以及用户的运动数据，运动数据可以包括心率、卡路里和运动步数等。
在一种实现中，穿戴设备可以在与第一设备建立连接后，将用户数据发送至第一设备。例如，上述穿戴设备为智能手表，用户佩戴智能手表进行运动；那么，智能手表在与第一设备建立连接后，可以实时将采集的用户的运动数据发送至第一设备，相应的，第一设备在接收到来自智能手表的用户数据后，可以显示该用户的运动数据。
在一些实施例中，穿戴设备在第一次与第一设备建立连接时，可以显示提示消息，该提示消息用于提示用户是否向第一设备发送用户设备；穿戴设备在接收到用户同意发送用户数据的用户操作时，可以将用户数据发送至第一设备；在后续连接中，穿戴设备与第一设备建立连接后可以直接实时向第一设备传输用户数据。
S103:第一设备显示媒体数据和用户数据。

在一些实施例中，第一设备可以响应于针对媒体数据的分享操作(如图8B所示的针对分享控件822 的用户操作)，通过设备发现功能扫描附近预设范围内可供连接的设备，例如通过局域网或蓝牙进行设备发现；进而，第一设备可以显示待分享设备信息和附属设备信息，其中，待分享设备信息包括一个或多个通过设备发现功能扫描发现的设备，附属设备信息包括一个或多个第一设备当前已连接的设备。
例如，第一设备发现到的设备为大屏设备A、大屏设备B以及PC，第一设备的附属设备为智能手表和无线耳机，则第一设备可以显示如图8C所示的用户界面83，该用户界面83包括待分享设备信息831、附属设备信息832，其中，待分享设备信息831用于显示第一设备发现的设备；附属设备信息832用于显示第一设备的附属设备。
在一种实现中，第一设备可以从发现的设备中，将具备显示功能的设备确定为待分享设备；也就是，待分享设备信息中的设备均为具备显示功能的设备。若第一设备通过设备发现功能扫描到的设备不具备显示功能，则第一设备不显示该设备。
S105:第一设备响应于选中穿戴设备的用户操作，确定第二设备为该穿戴设备。
其中，穿戴设备可以为一个或多个。需要说明的是，此处以穿戴设备为例，在其他实施例中，用户选中的设备也可以为其他附属设备，如音箱等。
在一些实施例中，用户可以从第一设备显示的附属设备信息中选择一个或多个穿戴设备，相应的，第一设备响应于用户选中穿戴设备的用户操作，确定分享的附属设备为该穿戴设备。例如，第一设备显示的附属设备信息如图8C所示，该附属设备信息包括智能手表和无线耳机，第一设备响应于用户针对智能手表的选择操作，将智能手表确定为第二设备。

其中，穿戴设备的设备信息可以包括该穿戴设备的名称或MAC地址；媒体数据的标识用于获取该媒体数据，例如媒体数据的标识可以为统一资源标识符(Uniform Resource Identifier，URI)，如媒体数据为视频，则该媒体数据的标识可以为该视频的URI。
在一种实现中，第一设备响应于分享至大屏设备的用户操作，将媒体数据的标识和穿戴设备的设备信息一同发送至大屏设备。例如，参见图8C，第一设备在检测到针对连接控件833的用户操作时，将媒体数据和智能手表的设备信息发送至大屏设备A。
在另一种实现中，第一设备也可以分别将媒体数据的标识和穿戴设备的设备信息发送至大屏设备。例如，第一设备可以在确定第三设备为大屏设备时，先将媒体数据发送至大屏设备；进而，在确定第二设备为穿戴设备时，再将穿戴设备的设备信息发送至大屏设备。
在另一些实施例中，第一设备可以将媒体数据和穿戴设备的设备信息发送至大屏设备，其中，媒体数据可以是第一设备本地存储的，也可以是第一设备从其他设备获取的，此处不作限定。
S108:大屏设备基于媒体数据的标识，播放该媒体数据。
在一些实施例中，大屏设备在接收到来自第一设备的媒体数据的标识后，可以基于该媒体数据的标识，获取该媒体数据；进而，播放该媒体数据。例如媒体数据的标识为视频的URI，大屏设备在接收到视频的URI后，可以基于该URI，从服务器获取该视频；进而，播放该视频。

S109:大屏设备在接收到穿戴设备的设备信息后，发送可连接定向广播。
其中，穿戴设备的设备信息用于在大屏设备接收到连接请求时验证连接设备是否为穿戴设备；可连接定向广播包括大屏设备的设备信息。
在一些实施例中，大屏设备在接收到穿戴设备的设备信息后，可以发送针对穿戴设备的定向可连接广播，该定向可连接广播用于仅允许该穿戴设备进行连接。
需要说明的是，广播类型可分为四种：Connectable Undirected Event Type(可连接非定向型)、Connectable Directed Event Type(可连接定向型)、Scannable Undirected Event Type(可扫描非定向型)和Non-connectable Undirected Event Type(不可连接非定向型)。本申请实施例中，大屏设备进行广播采用的是可连接定向型。
S110:大屏设备向第一设备发送响应消息，该响应消息用于指示大屏设备已开启可连接定向广播。
在一些实施例中，大屏设备在广播可连接信号后，可以向第一设备发送连接请求，该连接请求用于请求穿戴设备进行连接。
S111:第一设备在接收到该响应消息后，向穿戴设备发送第二消息，该第二消息用于指示穿戴设备与大屏设备建立无线连接，该第二消息包括大屏设备的设备信息。
在一些实施例中，第一设备在接收到上述连接请求后，向附属设备发送大屏设备的设备信息。其中，大屏设备的设备信息可以包括大屏设备的名称或MAC地址。
在一种实现中，第一设备通过蓝牙通信向穿戴设备发送第二消息，则该第二消息具体为蓝牙指令。
S112:穿戴设备在接收到上述第二消息后，基于大屏设备的设备信息与大屏设备建立蓝牙通信连接。
在一些实施例中，穿戴设备从上述第二消息中获取大屏设备的设备信息后，向大屏设备发起连接，即向大屏设备发送连接请求，该连接请求包括穿戴设备的设备信息；大屏设备在验证该连接请求中的设备为第一设备发送的穿戴设备的设备信息时，与该穿戴设备建立蓝牙通信连接。
在另一些实施例中，穿戴设备从上述第二消息中获取大屏设备的设备信息后，先通过蓝牙发现大屏设备，即确定上述可连接定向广播中的设备信息为大屏设备的设备信息；进而，向大屏设备发起连接，即向大屏设备发送连接请求，该连接请求包括穿戴设备的设备信息；大屏设备在验证该连接请求中的设备为第一设备发送的穿戴设备的设备信息时，与该穿戴设备建立蓝牙通信连接。
S113:穿戴设备基于上述蓝牙通信连接，向大屏设备发送用户数据。
在一些实施例中，穿戴设备在与大屏设备建立通信后，可以将发送至第一设备的用户数据发送至大屏设备。其中，穿戴设备向大屏设备发送的用户数据可以与步骤S102中发送至第一设备的用户数据相同，此处不再赘述。
需要说明的是，穿戴设备在向大屏设备发送用户数据后，可以停止向第一设备发送用户数据；也可以继续向第一设备发送用户数据，此处不作限定。
S114:大屏设备在接收到来自穿戴设备的用户数据后，显示该用户数据。
在一些实施例中，大屏设备在接收到来自穿戴设备的用户数据后，可以在显示屏上同时显示第一设备发送的媒体数据和穿戴设备发送的用户数据。
例如，大屏设备在接收到来自第一设备发送的瑜伽课程和来自智能手表的用户数据后，可以显示如图9所示的用户界面90，该用户界面90可以包括主窗口901和附属窗口902，其中，主窗口901用于显示瑜伽课程；附属窗口902用于显示智能手表数据。
在另一些实施例中，第三设备在接收到附属设备的数据后，也可以通过麦克风播放该数据，此处对第三设备对接收到数据的处理不作限定。
如图10所示，在图10所示的方法实施例中，第一设备先向大屏设备发送第一消息；在接收到大屏设备发送的响应消息时，再向穿戴设备发送第二消息。需要说明的是，第一设备也可以不需要等待来自穿戴设备或大屏设备的响应消息，第一设备可以在向大屏设备发送第一消息的同时，向穿戴设备发送第二消息。
在其他实施例中，第一设备也可以先向穿戴设备发送第二消息，再向大屏设备发送第一消息，具体可参加下文图11所示的实施例。需要说明的是，图10中的第一消息与图11中的第一消息不同，图10中的第二消息与图11中的第二消息不同。示例性的，以第一消息为例，图10和图11中的第一消息均用于指示大屏设备与穿戴设备建立通信连接，但是图10和图11中的第一消息携带的具体内容可以不同，图10中的第一消息具体用于指示大屏设备发送针对穿戴设备的可连接定向广播；图11中的第一消息具体用于向穿戴设备发起蓝牙连接，具体可参见图10和图11中的相关描述，此处不再赘述。
需要说明的是，上述步骤S104至步骤S107示例性提供了第一设备基于用户操作确定媒体数据、第三设备以及第二设备的一种实现，不应造成对本申请实施例的限定。
在另一些实施例中，第三设备和第二设备可以是默认的。
例如，第三设备和第二设备为第一设备上一次分享数据的第三设备(如大屏设备)和第二设备(如穿戴设备)；在图8B所示的用户界面82中还可以包括第一设备上一次分享数据的第三设备和第二设备；分享控件822用于指示将当前播放窗口821对应的视频资源分享至第一设备上一次分享数据的第三设备和第二设备。那么，第一设备可以显示用户界面82，进而，在检测到用户针对分享控件822的用户操作时，执行S107:第一设备响应于分享至大屏设备的用户操作，将媒体数据和穿戴设备的设备信息发送至大屏设备，也即是说，针对分享控件822的用户操作即为上述分享至大屏设备的用户操作。
本申请实施例中，穿戴设备与大屏设备建立无线连接包括但不限于蓝牙连接，还可以是其他连接方式，如局域网等，此处不做限定。
以下示例性提供穿戴设备与大屏设备建立无线连接的其他实现方式。
需要说明的是，在图10所示的实施例中，穿戴设备为具备切换主机(master)和从机(slave)角色的设备，在穿戴设备和第一设备的无线连接中，穿戴设备为slave；步骤S109至S112中，穿戴设备为master。其中，master为主动发起连接的设备，slave为广播以被其他设备发现后连接的设备。
在另一些实施例中，穿戴设备不具备切换主机(master)和从机(slave)角色的能力，则穿戴设备可以通过以下图11的方法实现穿戴设备与大屏设备建立蓝牙通信连接。
请参见图11，图11是本申请实施例提供的一种穿戴设备与大屏设备建立无线连接的方法流程图。需要说明的是，上文中步骤S109至S112，可以替换为上文中步骤S202至S205。
