可选的，上述智能交互设备可以通过HDMI接口与接收设备相连，也可以通过HDMI接口以及音频接口与智能交互设备相连，设置为在投放图像数据的同时，投放音频数据。
可选的，根据本申请上述实施例，智能交互设备包括：显示设备，设置为显示待投屏数据中的图像数据；触摸框，设置为将触摸信号传输至接收设备。
可选的，智能交互设备的触摸框通过USB接口与接收设备的USB相连，设置为 将触摸信号传输至接收设备，并由接收设备传输至待投屏终端。
可选的，根据本申请上述实施例，上述系统还包括：发声装置，设置为播放待投屏数据中的音频数据。
可选的，上述发声装置通过音频接口与接收设备相连。
图4是根据本申请实施例的一种可选的无线传屏系统的示意图，结合图4所示，该实施例中的接收设备即为无线传屏接收器，无线传屏接收器通过无线与网络通信，并与公网相连。当用户将无线传屏接收器的HDMI接口与智能交互平台相连时，即可以将PC的投屏数据投放至智能交互平板。同时，无线传屏接收器还可以包括另一个HDMI接口，该接口可以与其他设备相连，例如显示器等，显示屏和智能交互平板可以显示由一个PC投屏的相同内容，也可以显示由多个PC投屏的不同内容。
可选的，如果需要使用智能交互平板对PC进行反向控制，则可以将智能交互平板的触摸框的USB接口与无线传屏接收器的USB接口相连，如果投屏数据中包括音频，则可以将无线传屏接收器的音频接口与功放相连。
上述本申请实施例序号仅仅为了描述，不代表实施例的优劣。
在本申请的上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上所述仅是本申请的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
工业实用性
如上所述，本申请至少部分实施例提供的接收设备和无线传屏系统具有以下有益效果：通过路由模块建立无线网络，并将待投屏终端接入无线网络，通过第一接口与目标设备连接，通过主控制器与路由模块和第一接口相连，设置为通过无线网络接收待投屏终端发送的待投屏数据，并将数据通过第一接口传输至目标设备。当该接收设备与其他设备相连，则能够实现将待投屏终端的投屏数据投屏至与接收设备相连的其他设备，对于不具有无线投屏功能的设备，无需进行内部结构的改造，只需与该接收设备相连，即可具备无线投屏的功能，解决了现有技术中部分设备不具有无线传屏功能的技术问题。
