具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将结合附图对本公开的实施方式作进一步地详细描述。
图1为本公开的实施例提供的数据传输系统的示意图。如图1所示，该数据传输系统包括数据加载装置101和数据解析装置102。该数据加载装置101可以为具有视频播放功能的电子设备，如电视机、电脑等，该数据解析装置102可以为具有拍摄功能的电子设备，如智能手机、平板电脑等，但是本公开的实施例对此不做具体限定。
该数据加载装置101可以利用待传输数据对待播放视频的原始视频数据进行处理以得到目标视频数据，并在播放视频时显示该原始视频数据和该目标视频数据。数据解析装置102可以通过拍摄或扫描的方式采集数据加载装置101在播放视频时显示的原始视频数据和目标视频数据，并解析该原始视频数据和该目标视频数据以得到该待传输 数据。换句话说，数据传输系统可以通过正在播放的视频的视频帧进行数据传输。由于视频帧的显示和采集均在可见光波段上进行，因此数据传输系统进行数据传输时不需要占用无线频谱资源，可以不受有限的无线频谱资源的限制。
图2是根据一实施例的一种示例性数据传输方法的流程图。如图2所示，该数据传输方法包括以下步骤201-204。
在步骤201处，数据加载装置获取原始视频数据。
在步骤202处，数据加载装置获取待传输数据。
在步骤203处，数据加载装置根据待传输数据对原始视频数据进行处理以得到目标视频数据。因此，目标视频数据包括经处理后的原始视频数据，并且能够反映待传输数据。
在步骤204处，数据加载装置显示目标视频数据和原始视频数据。
综上所述，在本公开的实施例提供的数据传输方法中，数据加载装置用待传输数据对原始视频数据进行处理以得到目标视频数据，并显示该原始视频数据和目标视频数据，然后采集到所显示的原始视频数据和目标视频数据的数据解析装置能够解析该原始视频数据和该目标视频数据以得到待传输数据。由于原始视频数据和目标视频数据的显示和采集均在可见光波段上进行，因此无需占用无线频谱资源。故而，本公开的实施例提供的数据传输方法可以不受有限的无线频谱资源的限制。
图3A是根据一实施例提供的另一种数据传输方法的流程图。如图3A所示，该数据传输方法可以实施于如图1所示的数据传输系统中，并可以包括以下步骤301-306。
在步骤301处，数据加载装置获取原始视频数据和待传输数据。
本公开的实施例提供的数据加载装置可以在播放视频时进行数据传输。为了实现这一目的，数据加载装置需要获取待播放视频的视频数据和待传输数据，其中，该待播放视频的视频数据是上文所述的原始视频数据。该原始视频数据包括多个原始视频帧，每个原始视频帧包括多个原始像素点。这样，在后续步骤中，数据加载装置就可以利用该待传输数据对原始视频数据进行处理以得到目标视频数据，并基于该原始视频数据和目标视频数据进行视频播放，从而在播放视频过程中进行数据传输。
在一些实施例中，数据加载装置可以接收遥控器、数据解析装置等设备发送的视频播放指令，该视频播放指令用于指示数据加载装置播放视频。在接收到该视频播放时指令后，数据加载装置可以获取原始视频数据。而后，数据加载装置还可以接收遥控器、数据解析装置等设备发送的数据传输指令，并在接收到该数据传输指令后获取待传输数据。当然，在一些实施例中，该数据加载装置也可以在接收到上述视频播放指令后获取原始视频数据和待传输数据两者。此外，在一些实施例中，该数据加载装置还可以在播放视频之前获取该待传输数据。当数据加载装置获取到了该待传输数据，且检测到自身正在播放视频时，数据加载装置可以获取该原始视频数据，以在播放视频时进行数据传输。在这种情况下，数据加载装置可以通过弹窗、提示音等方式提示用户利用数据解析装置接收数据。
例如，用户小明想要在观看视频的同时令自己的手机接收数据，此时，小明可以使用遥控器打开电视机，并可以使用遥控器控制电视机播放自己想要观看的视频“三生三世十里桃花”。而后，小明还可以使用遥控器向电视机发送数据传输指令，电视机在接收到该数据传输指令后可以获取本地存储的待传输数据，该本地存储的待传输数据可以为电视机根据用户的需求预先下载的视频数据等。
需要说明的是，上述数据加载装置获取原始视频数据和待传输数据的时机仅仅是示例性的，还可能存在其他的获取原始视频数据和待传输数据的时机。
数据加载装置可以根据待传输数据对原始视频数据进行处理，如步骤302和303所记载的。
在步骤302处，数据加载装置将待传输数据转化为多个二进制数据串。
数据加载装置可以将获取的待传输数据转化为二进制数据，并将该二进制数据拆分成多个二进制数据串。每个二进制数据串与一个原始视频帧对应，每个二进制数据串包括多个数据段，每个数据段与所述一个原始视频帧的一个原始像素点对应。
上述二进制数据串中包含的数据段的个数可以与该二进制数据串对应的原始视频帧中包含的原始像素点的个数相同。也即是，二进制数据串中的数据段与对应的原始视频帧中的原始像素点可以一一对应。 当然，上述二进制数据串中包含的数据段的个数也可以小于对应的原始视频帧中包含的原始像素点的个数。在这种情况下，原始视频帧中包含的部分原始像素点可以与二进制数据串的数据段对应，而另一些原始像素点则不与数据段对应，本公开的实施例对此不做具体限定。
需要说明的是，上述数据段的长度可以为1比特(英文：bit)。在该数据段的长度为1比特时，该数据段可以为0或1。当然，该数据段的长度还可以大于1比特，本公开的实施例对此也不做具体限定。
下面，仅以数据段的长度为1比特为例对上述将二进制数据拆分成多个二进制数据串的技术过程进行说明。数据段的长度大于1比特时的技术过程与数据段的长度为1比特的技术过程同理。
如图3B所示，数据加载装置可以将获取的待传输数据X1转化成长度为n比特的二进制数据X2，同时该数据加载装置还可以确定原始视频帧中包含的原始像素点的个数为s，则数据加载装置可以从二进制数据X2中由头至尾依次截取多个二进制数据串c，并保证每个截取的二进制数据串c的长度为s比特。这样截取的每一个二进制数据串c均与一个原始视频帧y对应，且，二进制数据串中的每一个数据段与对应的原始视频帧中的一个原始像素点对应。
需要说明的是，图3B所示的拆分二进制数据串的过程仅仅是示例性的，当然还存在其他的拆分方式。例如，数据加载装置可以从二进制数据X2中由尾至头依次截取该多个二进制数据串c，或者，数据加载装置截取的二进制数据串的长度可以小于s比特等，这不是限制性的。
如上所述，二进制数据串中的每一个数据段与二进制数据串对应的原始视频帧中的一个原始像素点对应。当然，数据段与原始像素点的对应方式可以有很多种，图3C、3D、3E和3F为本公开的实施例提供的四种示例性的对应方式。
如图3C所示，二进制数据串中的数据段可以按照图3C中箭头所示依次与原始视频帧y中的原始像素点d对应。也即是，原始视频帧中的原始像素点逐行由左至右依次与二进制数据串中的数据段对应。
如图3D所示，二进制数据串中的数据段可以按照图3D中箭头所示依次与原始视频帧y中的原始像素点d对应。也即是，原始视频帧中的原始像素点逐行首尾相接依次与二进制数据串中的数据段对应。
如图3E所示，二进制数据串中的数据段可以按照图3E中箭头所 示依次与原始视频帧y中的原始像素点d对应。也即是，原始视频帧中的原始像素点逐列由上至下依次与二进制数据串中的数据段对应。
如图3F所示，二进制数据串中的数据段可以按照图3F中箭头所示依次与原始视频帧y中的原始像素点d对应。也即是，原始视频帧中的原始像素点逐列首尾相接依次与二进制数据串中的数据段对应。
需要说明的是，图3C、3D、3E和3F所示的对应方式仅仅是示例性的，其并不能限制本公开。
在步骤303处，对于每个二进制数据串，数据加载装置根据二进制数据串的每个数据段对应的灰阶变化值更改每个数据段对应的原始像素点的灰阶值，以得到多个目标像素点。所述多个目标像素点组成一个目标视频帧，多个二进制数据串对应的多个目标视频帧组成目标视频数据。
下面，仅以数据段的长度为1比特为例对步骤303的技术过程进行说明。数据段的长度大于1比特时步骤303的技术过程与数据段的长度为1比特时步骤303的技术过程同理。
数据加载装置中可以存储有数据段与灰阶变化值的映射关系，该映射关系可以如表1所示：
表1
数据段 灰阶变化值
1 +n
0 -m
应当指出，上述灰阶变化值可以包括红色子像素的灰阶变化值、绿色子像素的灰阶变化值和蓝色子像素的灰阶变化值中的至少一个。
对于每个二进制数据串，数据加载装置可以基于存储的数据段与灰阶变化值的映射关系获取每个数据段对应的灰阶变化值，而后根据该灰阶变化值更改所述每个数据段对应的原始像素点的灰阶值。如表1所示，在数据段为0时，数据加载装置可以将该数据段对应的原始像素点的灰阶值减小第一变化值m，以及在数据段为1时，数据加载装置可以将该数据段对应的原始像素点的灰阶值增加第二变化值n。对每个数据段对应的原始像素点的灰阶值进行更改后可以得到多个目标像素点，该多个目标像素点可以组成一个目标视频帧。
例如，如图3G所示，原始视频帧y1中第一行的前3个原始像素 点分别为原始像素点d1、d2和d3，该原始像素点d1、d2和d3的灰阶值分别为50、65和50。若原始像素点d1、d2和d3对应的数据段分别为1、0和1，且上述表1中m和n的值均为5，则数据加载装置可以将原始像素点d1的灰阶值增加5以得到与该原始像素点d1对应的目标像素点h1，该目标像素点h1的灰阶值为55。同理，数据加载装置还可以得到与原始像素点d2和d3分别对应的目标像素点h2和h3，所述目标像素点h2和h3的灰阶值分别为60和55。对于原始视频帧y1中每一个原始像素点的灰阶值进行与上述原始像素点d1、d2和d3相同方式的更改后即可得到多个目标像素点，该多个目标像素点即可组成与原始视频帧y1对应的目标视频帧q1。目标像素点h1、h2和h3为目标视频帧q1中第一行的前3个目标像素点。应当指出，上述灰阶变化值可以包括红色子像素的灰阶变化值、绿色子像素的灰阶变化值和蓝色子像素的灰阶变化值。在这种情况下，将原始像素点d1的灰阶值增加5可以指将原始像素点d1的红色子像素的灰阶值、绿色子像素的灰阶值和蓝色子像素的灰阶值分别增加5，以得到目标像素点h1。
如上所述，在数据段为0时，数据加载装置可以将该数据段对应的原始像素点的灰阶值减小第一变化值m以得到对应的目标像素点，并且在数据段为1时，数据加载装置可以将该数据段对应的原始像素点的灰阶值增加第二变化值n以得到对应的目标像素点。然而，灰阶值的增加会使目标像素点的亮度相较于对应的原始像素点的亮度增加，而灰阶值减小会使目标像素点的亮度相较于对应的原始像素点的亮度减小。如图3H所示，数据段1对应的原始像素点的亮度L1比对应的目标像素点的亮度L2小，如图3I所示，数据段0对应的原始像素点的亮度L1比对应的目标像素点的亮度L2大。因此，数据加载装置可以基于目标视频帧中每一个目标像素点的亮度相较于对应的原始像素点的亮度的变化来加载待传输数据，而数据解析装置只需要判断目标像素点的亮度相较于对应的原始像素点的亮度的变化就可以解析出待传输数据。这种数据传输方式较为简单，且对数据解析装置的硬件要求较低。
需要说明的是，上述第一变化值m和第二变化值n可以由技术人员预先进行设定。在本公开的一个实施例中，m和n可以均为小于50的正数。应当理解，m和n的值越大目标像素点和对应的原始像素点 的亮度差异就越大，数据解析装置就越容易进行数据解析，但是视频画面也越容易失真。在本公开的一个实施例中，该m和n可以均为5，这一方面保证了数据解析装置可以容易地进行数据解析，另一方面也避免了出现视频画面失真的现象。
还需要说明的是，上述表1所示的内容仅仅是示例性的，其并不能限制本公开。在实施例中，数据段为0时，数据加载装置可以增加原始像素点的灰阶值，以及数据段为1时，数据加载装置可以减小原始像素点的灰阶值；或者，在数据段为0或1时，数据加载装置均可以增加原始像素点的灰阶值；或者，在数据段为0或1时，数据加载装置均可以减小原始像素点的灰阶值。本公开的实施例对此不做具体限定。
在步骤304处，数据加载装置显示目标视频数据和原始视频数据。
在实施例中，数据加载装置可以交替地显示原始视频数据中包含的原始视频帧和目标视频数据中包含的目标视频帧。例如，如图3J所示，数据加载装置可以在显示一帧原始视频帧y后，显示一帧与该原始视频帧y对应的目标视频帧q。或者，如图3K所示，数据加载装置可以在显示多帧原始视频帧y后，显示一帧与该多帧原始视频帧中最后一帧原始视频帧对应的目标视频帧q。当然，还可能存在其他的显示目标视频数据和原始视频数据的方式。
由于数据加载装置播放视频时每秒钟显示的原始视频帧和目标视频帧的个数较多，因此，本公开的实施例提供的数据传输方法的传输速率较高。以数据加载装置在播放全高清(英文：Full High Definition)视频时传输数据且数据段的长度为1比特为例，数据传输的速率可达：
1920×1080×30b/s＝7594Mb/s，
其中，1920为全高清视频帧每行包括的像素点的个数，1080为全高清视频帧每列包括的像素点的个数，30为全高清视频播放时每秒显示的原始视频帧的帧数。
在步骤305处，数据解析装置采集数据加载装置显示的目标视频数据和原始视频数据。
在实施例中，数据加载装置可以在进行数据传输之前通过弹窗或提示音等方式提示用户，用户接收到提示后可以打开数据解析装置的摄像头并通过摄像头拍摄或扫描的方式采集数据加载装置显示的目标 视频数据和原始视频数据。此外，用户还可以预先将数据解析装置置于预定位置，该预定位置为能够拍摄数据加载装置显示的内容的位置，然后数据加载装置在进行数据传输时可以向该数据解析装置发送数据接收指令，数据解析装置在接收到该数据接收指令后可以打开自身的摄像头，以通过摄像头拍摄或扫描的方式采集数据加载装置显示的目标视频数据和原始视频数据。
需要说明的是，在上述说明中提供的数据解析装置采集数据加载装置显示的目标视频数据和原始视频数据的方式仅仅是示例性的，还可能存在其他的采集方式。
在步骤306处，数据解析装置解析原始视频数据和目标视频数据以得到待传输数据。
对于目标视频数据中的每一个目标视频帧，数据解析装置可以获取目标视频帧中每个目标像素点相较于对应的原始像素点的灰阶变化值并且获取每个灰阶变化值对应的数据段以得到二进制数据串，并将二进制数据串转化为原始数据。所述多个目标视频帧对应的原始数据可以组成待传输数据。
如上所述，数据解析装置可以通过判断目标视频数据中目标像素点的亮度相较于对应的原始像素点的亮度变化而解析出待传输数据。例如，图3L示出了6个目标像素点相较于各自对应的原始像素点的亮度变化示意图。根据该示意图，可知该6个目标像素点对应的数据段分别为1、1、0、0、1和0。
综上所述，在本公开的实施例提供的数据传输方法中，数据加载装置用待传输数据对原始视频数据进行处理得到目标视频数据，并显示该原始视频数据和目标视频数据，使得采集到显示的原始视频数据和目标视频数据的数据解析装置能够根据该原始视频数据和该目标视频数据解析得到该待传输数据。由于原始视频数据和目标视频数据的显示和采集均在可见光波段上进行，因此无需占用无线频谱资源，故而，本公开的实施例提供的数据传输方法可以不受有限的无线频谱资源的限制。
