本发明涉及图像传输技术领域，特别涉及一种图像传输的方法及系统。
背景技术
随着三网融合技术的发展，多屏幕共享业务可以使当前终端设备所浏览的视频信息及时地发送给其他终端设备，以实现多个屏幕共享该视频数据。多屏共享主要是指由不同的终端的屏幕显示相同的内容。
然而各种终端的屏幕大小、分辨率不同，各个终端的解码能力也不同，因此，如果发送端将视频数据，即图像进行广播后，若各个不同的接收端终端均做相同的图像处理，必然导致某些接收端终端不能正常处理所述图像，影响用户的收看效果。
发明内容

本发明提供的图像传输系统，包括视频发送端和至少一个视频接收端，
所述视频发送端包括：
图像分割模块，用于将视频发送端所要发送的图像分割为主要部分和至少一个次要部分；
图像配置模块，用于依照分割情况配置图像的主要部分和次要部分的位置关系信息；
图像主要部分编码模块，用于将所述图像主要部分进行编码；

附图说明
图1为本发明提供的图像传输方法的流程示意图；
图2为图像分割示意图；
图3-5为图像分割的另一示意图；
图6为本发明图像传输系统的示意图。
具体实施方式
本发明实施例提供了一种图像的传输方法和系统，下面将结合附图，对本发明实施例进行详细描述。参见图6，本系统包括视频发送端和一个以上的视频接收端，其中，视频发送端采用广播的方式广播视频数据，所述视频数据为多帧图片数据。其中，视频接收端可为电视机、笔记本电脑、手机以及PAD等。将在后文对该系统进行详细描述。
如图1所示，本发明提供的图像传输方法包括以下步骤：
步骤10：视频发送端将屏幕图像分割为主要部分与次要部分，其中，可以将屏幕图像分割为左、右、 上、中、下五部分并进行缓存，其中，屏幕的中间部分可以为主要部分，其他四部分为次要部分，参见图2所示。
不难理解，也可以采用其他图像分割方法，例如：延长列边缘线，对屏幕画面进行分割，参见图3所示。
又如，还可同时延长行边缘线和列边缘线，对屏幕画面进行分割，参见图4所示。
另外，可延长其中的一条行边缘线和一条列边缘线，对屏幕图像进行分割，参见图5所示。
步骤20：视频发送端将各部分图像进行分别编码，并在编码后形成的各部分图像数据包的包头内加入表示该部分图像位置的标识符，然后将各部分图像的数据包进行广播发送。
其中，本实施例中位于上、下、左、右、中五部分图片可以用分别表示相应位置的标识符表示其位置，如用三字节的000、001、010、011、100分别进行表示，并加入相应的图像数据包中。所广播的图像的各个部分还携带表示属于同一帧图像的信息，便于接收方识别。
其中， 对于图像的主要部分和次要部分，可以采用不同的编码方式发送。例如，可以将图像的次要部分采用有损编码方式降低该部分的像素、分辨率等方式，这是因为图像的次要部分相对主要部分被用户眼睛所聚焦的概率要小的多，这种方式可以加快发送端编码速度，也便于视频接收端加快解码速度。
步骤30：各个视频接收端根据自身屏幕等属性，接收图像主要部分的数据包，并有选择的接收次要部分的数据包，并进行缓存。
视频接收端首先检测自身的屏幕大小以及所能显示的分辨率、解码率等。依据自身的屏幕大小以及所能显示的分辨率选择接收适合自身的图像的次要部分。
例如： PAD由于屏幕的长度较大，宽度较小，根据其屏幕属性， PAD选择接收屏幕图像的左、右、中三部分图像，则在步骤30中，仅选择接收主要部分的图像数据包和左、右部分的次要部分的图像数据包。不难理解，若将PAD进行90度旋转，则PAD由其重力感应器判断出屏幕当前所放置的位置状态，即当前屏幕大小长宽数值发生调换，选择接收屏幕图像的上、中、下三部分图像。
又如，大屏电视由于屏幕较大，适于显示完整的图像，因此大屏电视可接收屏幕图像主要部分和选择接收所有次要部分，即接收的上、下、左、右、中五部分的图像。
再如，手机由于屏幕较小，可只选择接收屏幕图像的主要部分，即中间部分图像。
步骤40：各个视频接收端根据接收的数据包包头中的位置标识符，将图像主要部分和选择接收的次要部分分别进行解码后，进行组合显示。
不难理解，为了使得图像组合准确，发送图像时，各个图像要携带均表示属于由一帧图像分割的信息，例如视频中的时间信息或帧标识信息，以在进行图像组合时不会错帧组合。
另外，对于上述步骤20中，在视频发送端广播各个图像数据包时，还可以携带图像属性数据，例如分辨率（即图像大小），这样当视频接收端屏幕不小于发送端的屏幕大小时，其就可以根据图像属性数据判断出其可接收全部数据时，则接收全部图像数据。
如图6所示，本发明所提供的图像传输系统，包括视频发送端61和至少一个视频接收端62，其中，
所述视频发送端61包括：
图像分割模块611，用于将视频发送端61所要发送的图像分割为主要部分和至少一个次要部分；
图像配置模块612，用于依照分割情况配置图像的主要部分和次要部分的位置关系信息、时间信息、帧标识信息以及图像属性数据；
图像主要部分编码模块613，用于将所述图像主要部分进行编码；
图像次要部分编码模块614，用于将所述图像次要部分进行编码；
图像发送模块615，用于发送经配置图像的主要部分和次要部分；
所述视频接收端62包括：
图像接收选择模块621，用于依据视频接收端62的屏幕属性参数选择接收图像的次要部分；
图像接收模块622，用于接收所述图像主要部分以及所图像接收选择模块621所选择的次要部分及所述位置关系信息、时间信息、帧标识信息和图像属性数据；
图像组合模块623，用于将接收的图像主要部分和次要部分进行组合显示。
由上，视频发送端将发送的图像分割为主要部分和次要部分，各个视频接收端接收图像的主要部分，并根据其屏幕的属性参数选择接收图像的次要部分，以实现各个视频接收端对视频发送端所广播的视频数据的正常处理，并可体现出最适合屏幕的显示效果。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，总之，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
