步骤S2023，通过所述传屏程序对所述一次封装数据包进行二次封装，以获得二次封装数据包；
其中，二次封装主要是为了网络传输需要，二次封装数据包可以是一个网络传输的数据包。
步骤S1024，将所述二次封装数据包和所述内容程序的源程序信息通过网络发送至所述接收终端，以使所述接收终端将所述二次封装数据包和源程序信息转发至所述目标计算机。
其中，所述源程序信息包括程序ID信息和版本信息，例如程序ID信息为某某浏览器，版本信息为V2.0版。
所述以使所述目标计算机调用所述内容程序的对应程序，并根据所述操作数据启动所述对应程序的步骤包括：
以使所述目标计算机根据所述ID程序信息和所述版本信息找到所述内容程

开启本地通信服务；
通过所述本地通信服务建立所述传屏程序和所述内容程序的连接关系。
其中，本地通信服务可以是专门用于本地通信的socket服务，通过该socket服务能够建立所述传屏程序和所述内容程序的连接关系，保证内容程序能够将一次封装数据包发送至传屏程序。
请参阅图4，本发明第二实施例提出的无线传屏中信息共享的方法，应用在主计算机、多个副计算机、同时与所述主计算机和每个所述副计算机进行无线传屏的接收终端，每个计算机的画面分别对应显示在接收终端的各个分屏中，其中，主计算机、每个副计算机和接收终端都有一个传屏程序，主计算机中有一个内容程序，每个副计算机中有一个与该内容程序对应的对应程序，且每个计算机中都存在一个系统服务进程，主计算机中的传屏程序和内容程序的通信会借助该系统服务进程来完成，主计算机中的传屏程序与内容程序各自都会开启一个监听服务用于监听系统服务进程发出的推送，副计算机同理。所述方法包括：
S201，当主计算机的系统服务进程监听到主计算机的传屏程序和内容程序发生重叠，且传屏程序位于内容程序的下层时，主计算机的系统服务进程向主计算机的传屏程序发出推送信息，所述推送信息携带内容程序在传屏程序中的坐标；
S202，主计算机的传屏程序解析所述推送信息，以获取目标分屏及目标分屏对应的目标副计算机，主计算机同时打开本地通信服务，并向主计算机的系统服务进程发送反馈信息；
S203，主计算机的系统服务进程接收到反馈信息后，转推送到主计算机的内容程序；
S204，主计算机的内容程序监听到主计算机的系统服务进程的推送后，对
用户操作该内容程序时产生的状态数据以及用户数据进行封装，然后通过本地通信服务与主计算机的传屏程序建立连接，并将封装好的数据发送给主计算机的传屏程序；
S205，主计算机的传屏程序接收到封装好的数据后，进行二次封装，再附加上源程序信息，得到二次封装数据包，并将该二次封装数据包转发给接收终端的传屏程序；
S206，接收终端的传屏程序将该二次封装数据包转发至目标副计算机，目标副计算机对二次封装数据包进行解析，并发起调用与主计算机的内容程序对应的对应程序，将状态数据以及用户数据作为参数传递给该对应程序；
S207，目标副计算机中的对应程序在启动时检查参数，按状态数据以及用户数据还原用户的操作状态及数据。
此外，上述方案中使用到的传屏程序与内容程序间的通信模块，统一封装为SDK，给到应用开发商进行接入，而系统服务进程是安装到系统中进行自启动。可以理解的，具体实施时，可以通过使用系统API接口提供给内容程序的应用厂商进行应用集成和自身对预装应用进行二次开发的时候使用，而这套API主要负责功能为传屏程序与内容程序的通信。
下面给出一个具体应用环境，会议中，用户1、用户2、用户3和用户4在各自的电脑上启动传屏软件进行桌面传送(无线传屏)，每台电脑上的桌面内容都被传送至会议平板中进行分屏显示。展示中，用户1正在用浏览器查看某站点的内容，这时候用户1需要用户2也打开同样的站点并浏览里面某部分的内容的时候，通过此方案，用户1只需要将浏览器拖拽到传屏软件中用户2对应的分屏中，用户2那边会自动打开相应的浏览器并跳转到对应站点上的内容位置。
