图1为移动终端与智能电视无线高清数据传输的连接框图。如图1所示，智能电视1中集成有无线高清数据接收器2，移动终端3与无线高清数据接收器建立无线高清数据投影通道，通过该无线高清数据投影通道可以将移动终端3上的高清视频推送至无线高清数据接收器2，进而由无线高清数据接收器传输至智能电视1，实现移动终端3和智能电视1的同屏显示。
基于上述原理，本发明实施例提供了一种检测无线高清数据投影通道被遮挡的方法和装置，以解决使用WiHD(Wireless hdmi，无线高清)技术传输高清数据的过程中出现连接不稳定或者是连接信号中断时，能够定位故障，并及时的排除遮挡的问题。
实施例一
参照图2，示出了本发明实施例一提供的一种检测无线高清数据投影通道被遮挡的方法的步骤流程图。
本发明实施例提供了一种检测无线高清数据投影通道被遮挡的方法，如图1所示，可以包括以下步骤：
步骤S201，移动终端与高清数据接收器建立无线高清数据投影通道。
在本步骤中，移动终端可以是手机、平板电脑等具有视频播放功能和WiHD功能的终端。在与高清数据接收器(dongle)建立无线高清数据投影通道之前，移动终端需要开启WiHD功能。移动终端可以通过读取NFC((Near Field Communication，近距离无线通讯技术)标签中连接信息的方式与高清数据接收器建立WiHD连接，从而实现建立无线高清数据投影通道。其中连接信息可以包括：无线高清接收器的标示信息和地址信息。
步骤S202，通过无线高清数据投影通道向无线高清数据接收器发送验证消息。
在本步骤中，验证消息可以是固定的消息(message)。优选地是，以预设的周期，通过无线高清数据投影通道向无线高清数据接收器发送验证消息，该预设周期可以是100ms。
步骤S203，判断是否接收到无线高清数据接收器依据验证消息反馈的应答消息。
在本步骤中，无线高清数据接收器在接收到验证消息之后，可以向移动终端反馈应答消息。移动终端若未接收到应答消息，则可以执行步骤S204；若接收到应答消息，则可以执行步骤S206。
步骤S204，产生无线高清数据投影通道状态变化的事件(uevent)。
在本步骤中，产生无线高清数据投影通道状态变化的事件则标志着无线高清数据投影通道被障碍物遮挡。
步骤S205，依据无线高清数据投影通道状态变化的事件，显示无线高清数据投影通道被遮挡的提示。
在本步骤中，用户可以依据该提示，及时的调整无线高清数据接收器与移动终端的位置，排除遮挡。
步骤S206，产生无线高清数据投影通道状态无变化的事件。
在本步骤中，标志着移动终端和无线高清数据接收器均工作正常，且无线高清数据投影通道无遮挡。
步骤S207，依据无线高清数据投影通道状态无变化的事件，显示无线高清数据投影通道通畅的提示。
在本步骤中，若移动终端上显示无线高清数据投影通道通畅的提示，但是依然不能实现移动终端和智能电视的同屏显示，则可以断定是智能电视故障。
通过本发明实施例一提供的一种检测无线高清数据投影通道被遮挡的方法，移动终端向无线高清数据接收器发送验证消息，并判断是否接收到无线高清数据接收器反馈的应答消息，若未接收到，则可以定位是移动终端和无线高清数据接收器之间的无线高清数据投影通道被遮挡，显示无线高清数据投影通道被遮挡的提示，提示用户及时的调整无线高清数据接收器与移动终端的位置，排除遮挡。
在本发明优选实施例中，可以将上述步骤S203优化为：在预设的时间内，判断是否接收到无线高清数据接收器依据验证消息反馈的应答消息；相应的将上述步骤S204优化为，若在预设的时间未收到应答消息，则产生无线高清数据投影通道状态变化的事件。该预设时间可以是200ms。由此可以提高判断移动终端和无线高清数据接收器之间的无线高清数据投影通道被遮挡的效率。
