具体实施方式
为使本申请的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本申请作进一步详细的说明。
首先，对本申请涉及的相关概念做简单说明。
无线高清(WirelessHD，WiHD)技术是一种很让用户期待的高速无线技术，这主要在于它运用了60GHz频段(毫米波)的频谱，能够取得更 大的数据传输速率，其最初的传输速率便高达4Gbps，从而能更可靠地提供传输高质量、高清晰度无压缩视频所必要的频宽。
移动终端高清影音标准接口(Mobile High-Definition Link，MHL)是一种连接便携式消费电子装置的影音标准接口，MHL仅使用一条信号电缆，通过标准HDMI即可呈现于高清电视上。它运用了现有的Micro USB接口，不论是手机、数码相机、数字摄影机还是便携式多媒体播放器，皆可将完整的媒体内容直接传输到电视上且不损伤影片高分辨率的效果。
在本实施例中，移动终端设备可包括手机、平板电脑等，接收设备可为大屏扩展播放设备，比如智能电视、投影仪等。
参看图1，示出了本申请数据处理方法实施例一的流程示意图。
该数据处理方法应用于移动终端设备，在移动终端设备中可预置兼容无线高清协议(WiHD协议)和移动终端高清影音标准接口协议(MHL协议)且具有发射功能的WiHD/MHL芯片，且该移动终端设备设置有第一MHL。
在本实施例中，该方法包括如下步骤：
S101，当接收到将移动终端设备的显示界面共享到接收设备的指令时，对显示界面的图像数据进行截取。
在本实施例中，移动终端设备可为设置有WiHD/MHL芯片的智能手机，接收设备可为兼容WiHD协议、MHL协议的智能电视。
其中，当接收到将移动终端设备的显示界面共享到接收设备的指令，比如可为：当用户在家中想将手机的显示界面共享到智能电视中观看，则可启动手机中的预置同屏共享应用，并在该应用界面中触发预置的与同屏共享相关的按钮。
由于移动终端设备的显示界面可以是静止界面(比如开机后的首页面、在预置的相册应用中查看某一照片等)，也可以是动态界面(比如播放视频文件、音频文件的界面、游戏界面等)，因此，在当接收到将移动终端设备的显示界面共享到接收设备的指令后，还可包括判断显示界面是否为静止界面的步骤。
判断显示界面是否为静止界面，可根据当前显示界面所对应的应用的属性(比如名称等)进行判断。比如，当前显示界面为照片，该照片所对 应的应用为“相册”，根据相册的属性可知其显示界面为静止界面；再比如，当前显示界面为正在播放音频文件，该音频文件所对应的应用为“天天动听”，根据“天天动听”的属性可知其显示界面为动态页面。
若判断结果为是，也就是移动终端设备的显示界面为静止界面，则只需从预置缓存中截取一次显示界面的图像数据，即获取当前界面的图像数据即可，以尽量减少对内存资源的浪费。
若判断结果为否，也就是移动终端设备的显示界面为动态界面，则需从预置缓存中实时截取显示界面的图像数据，该实时截取的频率比如可以是60帧/秒或者30帧/秒获取一次，以更精确地将移动终端设备的显示界面中的图像同步显示于多媒体设备接收端上。
S102，在检测到有接收设备与移动终端设备建立通信连接时，判断需要使用的目标传输协议。其中，该目标传输协议为WiHD协议或MHL协议。
在本实施例中，可通过接收到有由WiHD/MHL芯片发送来的有接收设备与移动终端设备建立通信连接的上报信号，来确定检测到接收设备与移动终端设备建立通信连接，具体而言，当接收到由WiHD/MHL芯片发送来的有接收设备通过WiHD协议与移动终端设备建立无线通信连接的信号和/或有接收设备通过第一MHL与移动终端设备建立有线通信连接的信号，则可确定有接收设备与移动终端设备建立了通信连接。
在确定有接收设备与移动终端设备建立了通信连接后，则还要进一步判断需要使用的目标传输协议，以便通过判断出的需要使用的目标传输协议将数据传输到相应的接收设备。
具体的，若检测到有由WiHD/MHL芯片发送来的有接收设备通过WiHD协议与移动终端设备建立无线连接的上报信号，则判断出需要使用的目标传输协议为WiHD协议；或若检测到有接收设备通过第一MHL与移动终端设备建立有线连接的上报信号，则判断出需要使用的目标传输协议为MHL协议。
优选地，若检测到有由WiHD/MHL芯片发送来的有接收设备通过WiHD协议与移动终端设备建立无线连接的上报信号且有接收设备通过第一MHL与移动终端设备建立有线连接的上报信号，则可根据预置优先级传输标准确定需要使用的目标传输协议。该预置优先级传输标准可根据设计需求的不同 而设置，比如，在本实施例，该预置优先级传输标准为：在有接收设备通过WiHD协议与移动终端设备建立无线通信连接，且同时有接收设备通过第一MHL与移动终端设备建立有线通信连接的情况下，默认优先使用WiHD协议进行数据传输。
优选地，该第一MHL可单一功能的MHL，也可为MHL/USB接口的复用接口。
在该第一MHL为MHL/USB接口的复用接口的情况下，还可通过如下方式来判断需要使用的目标传输协议：
检测复用接口的检测端子ID的电压，若检测端子ID的电压为第一预定电压值时，则可判定有兼容MHL协议的接收设备通过该复用接口与移动终端设备建立通信连接，此时该复用接口作为MHL使用，可判断出需要使用的目标传输协议为MHL协议。其中，该第一预定电压值可为检测端子ID通过阻值为1K(千欧)的接地电阻接地的接地电压值。
若所述检测端子ID的电压为第二预定电压值或第三预定电压值，则可判定有OTG设备通过复用接口与移动终端设备建立通信连接，此时该复用接口则作为USB接口使用。其中，当OTG设备作为主设备(HOST)使用时，其连接线的检测端子ID是直接接地的，此时检测到的检测端子ID为第二预定电压值；当OTG设备作为从设备(SLAVE)使用时，其连接线的检测端子ID是悬空的或通过R2(R2＞100K)接地，通过设备内部上拉，此时检测到的检测端子ID为第三预定值。
S103，将显示界面的图像数据传送给WiHD/MHL芯片，以便由WiHD/MHL芯片对显示界面的的图像数据进行调制。
S104，将调制后的显示界面的图像数据通过S102中判断出的需要使用的目标传输协议传送给相应的接收设备，以便接收设备将接收到的显示界面的图像进行解调，并根据解调后的显示界面的图像数据进行同步显示，以实现移动终端设备与接收设备之间的同屏共享。
优选地，当移动终端设备正在播放音频文件、视频文件时，声音可由移动终端设备进行播放，也可将音频、视频文件中的音频数据进行实时提取，并通过确定的目标传输协议传给送给接收设备，以由接收设备同步播放，以进一步提升用户的听觉感受。
基于此，在上述判断出移动终端设备的显示界面为动态界面的情况下，还可继续判断该显示界面所对应的文件中是否包括音频数据，该判断可根据上述步骤中确定的显示界面所对应的应用，在该应用中找到该显示界面对应的文件，再判断该文件中是否包含音频数据。
比如，当前显示界面为正在播放视频，该视频所对应的应用为“搜狐视频”，在“搜狐视频”对应的预置缓存中找到该视频文件，可判断出该视频文件中包含音频数据；然后则可从预置缓存中实时提取该音频数据；再将提取出的音频数据传送给WiHD/MHL芯片且由WiHD/MHL芯片对所述音频数据进行调制；然后再将调制后的音频数据根据需要使用的目标传输协议传送给相应的接收设备，以便接收设备根据接收到的音频数据进行同步播放，进而可实现将移动终端设备中的图像、音频同步共享到接收设备上。
图2和图3为本申请数据处理方法实施例一中移动终端设备与接收设备的示意图(一)和(二)，下面以移动终端设备为智能手机、接收设备为智能电视为例并结合图2和图3对上述步骤进行进一步说明。
例一(参看图2)：
当用户在家中通过手机20查看手机中的某一照片时，想将该照片共享到家中的智能电视中观看，则可启动手机20中的预置同屏共享应用，并在应用界面中的预置位置找到“共享”并触发，然后选择共享目标即“智能电视”。其中，该手机包括MHL/USB接口的复用接口22。
当手机接收到上述操作后，则可先判断手机的显示界面21是静止界面还是动态界面，根据该查看的照片界面所对应的应用(比如名称为“相册”)的属性可知，此时的显示界面为静止界面，则只需从相册对应的预置缓存中截取一次显示界面的图像数据。
通过接收到由WiHD/MHL芯片发送来的有兼容MHL协议的接收设备30通过MHL协议与移动终端设备建立通信连接的上报信号，则可确定有接收设备30通过复用接口22与移动终端设备20建立了通信连接。
检测复用接口22的检测端子ID的电压，根据检测结果可知该检测端子ID的电压为第一预定电压值，因此，可判定接收设备30为兼容MHL协议的接收设备，则可判断出需要使用的目标传输协议为MHL协议。
将显示界面的图像数据传送给WiHD/MHL芯片，以便由WiHD/MHL芯 片对显示界面的的图像数据进行调制。
将调制后的显示界面的图像数据通过MHL协议传送给接收设备30，以便接收设备30将接收到的显示界面的图像数据进行解调，并根据解调后的显示界面的图像数据在智能电视界面31上进行同步显示，以实现移动终端设备20与接收设备30之间的同屏共享。
例二(参看图3)：
当用户在家中通过手机20观看手机中的某一视频文件时，想将该视频文件共享到家中的智能电视中进行观看，则可启动手机30中的预置同屏共享应用，并在界面中的预置位置找到“共享”并触发，然后选择共享到“智能电视”。
当手机接收到上述操作后，则可先判断显示界面21是静止界面还是动态界面，由于观看视频的界面所对应的应用为“搜狐视频”，则根据“搜狐视频”的属性可得知观看视频时的显示界面为动态界面，则需要从搜狐视频对应的缓存中实时截取显示界面的图像数据。
根据上述步骤中确定的显示界面所对应的应用(搜狐视频)，在该应用中找到该显示界面对应的文件(比如为“来自星星的你第三集”)，则可判断出该文件中包含音频数据，并实时提取该文件中的音频数据。
通过接收到由WiHD/MHL芯片发送来的有兼容WiHD协议的接收设备通过WiHD协议与移动终端设备建立无线通信连接的上报信号，则可确定有接收设备30与移动终端设备20建立了无线通信连接，且由此可判断出的需要使用的目标传输协议为WiHD协议。
将显示界面的图像数据、音频数据传送给WiHD/MHL芯片，以便由WiHD/MHL芯片对显示界面的的图像数据、音频数据进行调制。
将调制后的显示界面的图像数据、音频数据通过WiHD协议传送给的接收设备30，以便接收设备30将接收到的显示界面的图像数据、音频数据进行解调，并根据解调后的显示界面的图像数据在智能电视界面31上同步显示、根据解调后的音频数据进行同步播放，以实现移动终端设备20与接收设备30之间的同屏共享。
本申请实施例提供的数据处理方法，在移动终端设备中预置兼容WiHD协议和MHL协议且具有发射功能的WiHD/MHL芯片，以实现移动终端设备 既可与兼容WiHD协议的接收设备建立无线通信连接，又可与兼容MHL协议的接收设备建立有线通信连接，并可将调制后的显示界面图像、音频等数据通过基于WiHD协议的无线传输模式或基于MHL协议的有线传输模式传送给相应的接收设备，以使得接收设备根据接收到的数据同步显示图像、同步播放音频等，与现有通过WIFI连接进行数据传输的方式相比，数据传输速率和传输质量更高、传输过程更稳定，使得同屏共享过程无延时、图像质量好且更稳定，可提升用户的观看感受。此外，由于WiHD/MHL芯片的设置，可实现将数据调制后即可发送而无需压缩等步骤，进一步提高了数据处理速度，因而进一步保证了同屏共享过程的无延时，以提升用户的观看感受。
下面将介绍本申请提供的与上述对数据处理方法相对应的数据处理装置。
