为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领 域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
需要说明的是，本申请实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
技术术语解释：
服务集标识(Service Set Identifier，简称为SSID)，SSID技术可以将一个无线局域网分为几个需要不同身份验证的子网络，每一个子网络都需要独立的身份验证，只有通过身份验证的用户才可以进入相应的子网络，防止未被授权的用户进入本网络。
本申请实施例提供了一种投屏方法。
图1是根据本申请实施例的一种可选的投屏方法的流程图，如图1所示，该方法包括以下步骤：
步骤S102：通过通信接口与目标终端相连。
其中，通信接口为允许直接连入目标终端的硬件接口。
步骤S104：接收目标终端实时的屏幕显示数据和/或音频数据。
步骤S106：向接收端发送屏幕显示数据和/或音频数据。
其中，屏幕显示数据在接收端进行展示，音频数据在接收端进行播放。
通信接口可以是通用串行总线(Universal Serial Bus，简称为USB)接口或者其他硬件接口。目标终端可以是手机、电脑等，接收端可以是机顶盒、投影机、会议大屏、智能电视等，此处不做任何限制。
在本申请实施例中，投屏设备与目标终端通过通信接口进行连接，投屏设备接收目标终端实时的屏幕显示数据和/或音频数据，并向接收端发送屏幕显示数据和/或音频数据，在接收端接收到屏幕显示数据和/或音频数据之后，展示屏幕显示数据，和/或播放音频数据，目标终端不需要连接会议室中的特定WIFI热点，也无需开启图像镜像功能就能够进行投屏，从而解决了相关技术中用户第一次进行无线投屏时操作步骤繁琐复杂的技术问题，进而达到了简化用户操作的技术效果。
可选地，向接收端发送屏幕显示数据和/或音频数据，包括：将屏幕显示数据和/或音频数据进行编码压缩，得到压缩包；向接收端发送压缩包。
由于屏幕显示数据、音频数据的文件大小很大，在传输的时候要占用很大的带宽，因而对传输信道的要求较高。
当传输带宽较大的时候，可以不对屏幕显示数据和/或音频数据进行压缩，直接将屏幕显示数据和/或音频数据发送给接收端，在接收端接收到屏幕显示数据和/或音频数据之后，可以直接对屏幕显示数据和/或音频数据进行展示或播放；当传输带宽较小的时候，为了保证屏幕显示数据和/或音频数据的正常传输，可以先将屏幕显示数据和/或音频数据进行编码压缩，得到压缩包，然后向接收端发送压缩包，在接收端接收压缩包后，对压缩包进行解码，得到屏幕显示数据和/或音频数据，然后接收端将屏幕显示数据和/或音频数据进行播放或展示。
可选地，在将屏幕显示数据和/或音频数据进行编码压缩之前，确定与接收端之间的传输带宽；根据确定出的传输带宽选择对屏幕显示数据和/或音频数据进行编码压缩的目标格式。其中，将屏幕显示数据和/或音频数据进行编码压缩，包括：按照目标格式对屏幕显示数据和/或音频数据进行编码压缩。
通过根据传输带宽确定压缩格式，以合理的压缩格式对屏幕显示数据和/或音频数据进行压缩，既能够保证屏幕显示数据和/或音频数据的正常传输，又能够最大限度地利用传输带宽，并且，还能使得屏幕显示数据和/或音频数据在传输过程中的损失较小。
可选地，在接收目标终端实时的屏幕显示数据和/或音频数据之前，该方法还包括：投屏设备与接收端建立无线连接。
投屏设备与接收端建立无线连接的方式可以有多种，例如，投屏设备和接收端通过同一个局域网建立无线连接，或者，接收端具有无线热点功能，投屏设备和接收端通过无线热点功能进行无线连接。
在接收目标终端实时的屏幕显示数据和/或音频数据之前，该方法还包括：读取目标终端的设备信息，其中，目标终端的设备信息用于指示目标终端的设备类型和通信方式；根据读取到的设备信息查找目标驱动程序，其中，目标驱动程序用于接收屏幕显示数据和/或音频数据；加载目标驱动程序。
在检测到投屏设备通过通信接口插入之后，可以对投屏设备进行枚举，也即，从投屏设备中读取特定信息，以知道投屏设备是什么类型的设备，如何进行通信，这样就可以根据读取到的信息加载合适的驱动程序，以从目标终端中抓取屏幕显示数据和/或音频数据。
图2是根据本申请实施例的一种可选的实施投屏方法的硬件示意图，如图2所示，手机无线投影设备(即上述投屏设备)内的主芯片运行linux系统或其他智能系统，手机通过USB接口与智能系统连接，通过智能系统的设置，手机可以将手机无线投影设备识别为电脑，而在手机无线投影设备中，智能系统可通过特定软件与驱动将手机端的桌面显示与音频实时抓取出来，在ARM主芯片将此音视频编码压缩后，可以通过WIFI模块将音视频压缩包发送到显示接收端(即上述接收端)解码播放显示出来，其中，手机无线投影设备可以通过预设的WIFI连接密码和显示接收端通过WIFI无线连接在一起。手机不需要连接会议室中的特定WIFI热点，也无需开启图像镜像功能就能够进行投屏，从而解决了相关技术中用户第一次进行无线投屏时操作步骤繁琐复杂的技术问题，进而达到了简化用户操作的技术效果。
作为一种可选的实施例，投屏设备上电，通过软件中预设的密码与预设的WIFI SSID的无线热点连接。投屏设备通过USB接口与手机连接，手机作为从设备(device)在ARM芯片系统中进行USB设备枚举。在枚举完成之后，ARM主芯片中系统可以通过特定驱动和软件接口将手机中显示画面和音频实时抓取出来，并通过编码压缩处理成压缩包。ARM主芯片将音视频压缩包通过WIFI发送给接收端的特定端口。接收端可以将接收到的音视频编码压缩包解码播放出来。当用户想要将手机的内容实时投影到大屏上以进行显示分享时，只需要连接手机USB接口即可实现手机投屏，而并不需要繁杂的操作。
