无线传屏方法及系统 技术领域
本发明涉及计算机信息处理技术领域，特别是涉及一种无线传屏方法及系统。
背景技术
无线传屏技术主要实现将源端装置屏幕上显示的内容和声音同步到投影仪、电视机和会议平板等接收端装置进行展示，无线传屏技术能够将源端装置(如电脑)处理能力强和接收端装置(如电视机或会议平板)展示效果好的特点结合起来，因此得到了广泛应用。
现有的无线传屏技术主要采用传屏软件实现，在源端装置和接收端装置上均安装相应的传屏软件，同时保证源端装置和接收端装置在同一个无线网络中，即可实现多媒体信息(包括图片、音频、视频等)的无线传屏。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1，本发明第一实施例提出的无线传屏方法，应用于接收终端和与所述接收终端同时进行无线传屏的至少两台计算机，本实施例中，接收终端以会议平板为例进行说明，其中，所有的计算机和会议平板均安装了相应的传屏软件，同时所有的计算机和会议平板在同一个无线网络中，能够进行现有技术中的常规的无线传屏，且每台所述计算机的桌面图像分别显示在所述接收终端的对应分屏中，本实施例提出的无线传屏方法至少包括以下步骤：
S101，接收多台计算机中每台所述计算机检测到自身处于第一展示状态时所发送的第一反馈信息，所述第一展示状态为所述计算机在第一预设时间内检测到桌面图像发生变化，所有所述计算机同时与一接收终端进行无线传屏，每台所述计算机的桌面图像分别显示在所述接收终端的对应分屏中；
其中，所述第一反馈信息可以为所述计算机在所述第一预设时间内检测到窗口集合中位于最前端的桌面窗口发生切换时所产生的消息；其中，所述窗口集合为所述计算机通过操作系统API枚举桌面上的桌面窗口后所获取到窗体大小大于桌面三分之一的全部窗口。其中，当某个计算机的桌面上有多个桌面窗 口时，会首先枚举出所有的桌面窗口，例如枚举出的桌面窗口包括画图、word文档、代码编辑器、顶部工具栏，然后找到窗体大小大于桌面三分之一、且位于桌面最前端的当前桌面窗口，例如，窗体大小大于桌面三分之一的窗口有画图、word文档、代码编辑器，窗体大小大于桌面三分之一的窗口为顶部工具栏，在窗体大小大于桌面三分之一的窗口中，位于桌面最前端的当前桌面窗口为画图，则此时计算机会判断画图是否发生切换，若画图发生切换，例如，从画图切换成word文档，则该计算机判断自身处于所述第一展示状态。可以理解的，上述方法的其它情况，例如，在实际操作中，用户只操作了顶部工具栏，此时，会导致判断自身非处于所述第一展示状态。所述第一预设时间可以为10秒，即所述第一展示状态可以为计算机在10秒内检测到桌面窗口发生切换，此时该计算机会产生第一反馈信息，并将产生的第一反馈信息发送给会议平板。
此外，所述第一反馈信息还可以为所述计算机在所述第一预设时间内检测到窗口集合中位于最前端的桌面窗口的窗口布局发生变化时所产生的消息。具体实施时，所述计算机可以通过监听显卡信息监测到桌面内容发生变化，当监测到桌面内容发生变化时，通过操作系统API枚举桌面上的桌面窗口；然后检测窗口集合中位于最前端的桌面窗口的窗口布局是否发生变化，其中，窗口布局可以为窗口的“顺序以及大小”的分布。由于计算机桌面内容的变化并不一定表示需要展示的程序内容发生了变化，一些提示性信息(如QQ消息提醒)，也会导致桌面内容的变化，但此种情况并非用户想进行全屏展示的情况，上述的方法就是为了避免该种情况。计算机会通过监听显卡信息监测到桌面内容是否发生变化，若发生了变化，会通过操作系统API枚举桌面上的桌面窗口，例如，枚举出的桌面窗口包括画图、word文档、代码编辑器、顶部工具栏，然后找到窗体大小大于桌面三分之一、且位于桌面最前端的当前桌面窗口作为展示窗口，然后检测展示窗口之上的布局是否发生变化，例如展示窗口为画图，此时，计算机出现了QQ消息提醒，由于QQ消息提醒会导致画图之上的窗口布局发生了变化，则表明计算机通过监听显卡信息监测到的桌面内容的变化是由于QQ消息提醒引起的，因此不会判断自身处于所述第一展示状态；反之，只有当计算机通过监听显卡信息监测到的桌面内容发生了变化，且画图之上的窗口布 局未发生变化才会使计算机判断自身处于所述第一展示状态。
S102，当根据所述第一反馈信息判断到只有一台所述计算机处于所述第一展示状态时，将处于所述第一展示状态的所述计算机对应的分屏进行全屏显示。
其中，当有计算机产生第一反馈信息时，就会将产生的产生第一反馈信息发送至会议平板，会议平板根据检测结果进行统计，统计出处于所述第一展示状态的计算机的数量。
其中，将处于所述第一展示状态的所述计算机对应的分屏进行全屏显示具体可以通过以下步骤实现：
向处于所述第一展示状态的所述计算机发送请求信息，所述请求信息包括提高传输分辨率和码率，同时向处于所述第一展示状态以外的所有所述计算机发送暂停发送桌面图像的请求，以使处于所述第一展示状态的所述计算机根据所述请求信息提高传输分辨率和码率，同时使处于所述第一展示状态以外的所有所述计算机暂停发送桌面图像。
根据本发明实施例的无线传屏方法，每台计算机都会判断自身是否处于第一展示状态，例如只有其中一台计算机检测到自身处于该第一展示状态时，表明正在操作该计算机的用户希望他人关注自己的计算机展示的内容，此时，由于该计算机处于第一展示状态，接收终端会将该计算机对应的分屏进行全屏显示，从而实现了自动对多分屏中的该分屏进行全屏显示，避免了复杂的操作，提升了交互体验。
此外，作为一个具体示例，本实施例提出的无线传屏方法还包括：
当根据所述第一反馈信息判断到没有或至少有两台所述计算机处于所述第一展示状态时，保持分屏显示所有所述计算机的桌面图像。
请参阅图2，本发明第二实施例提出的无线传屏方法，应用于接收终端和与所述接收终端同时进行无线传屏的至少两台计算机，本实施例中，接收终端同样以会议平板为例进行说明，其中，所有的计算机和会议平板均安装了相应的传屏软件，同时所有的计算机和会议平板在同一个无线网络中，能够进行现有技术中的常规的无线传屏，且每台所述计算机的桌面图像分别显示在所述接收终端的对应分屏中，本实施例提出的无线传屏方法至少包括以下步骤：
S201，接收每台所述计算机检测到自身处于第二展示状态时所发送的第二反馈信息，所述第二展示状态为所述计算机在第二预设时间内检测到键盘输入信息和/或鼠标移动信息；
其中，所述第一预设时间也可以为10秒，即所述第二展示状态可以为计算机在10秒内检测到键盘输入信息和/或鼠标移动信息，此时该计算机会产生第二反馈信息，并将产生的第二反馈信息发送给会议平板。
S202，当根据所述第二反馈信息判断到只有一台所述计算机处于所述第二展示状态时，将处于所述第二展示状态的所述计算机对应的分屏进行全屏显示。
其中，当有计算机产生第二反馈信息时，就会将产生的产生第二反馈信息发送至会议平板，会议平板根据检测结果进行统计，统计出处于所述第二展示状态的计算机的数量。
其中，将处于所述第二展示状态的所述计算机对应的分屏进行全屏显示具体可以通过以下步骤实现：
向处于所述第二展示状态的所述计算机发送请求信息，所述请求信息包括提高传输分辨率和码率，同时向处于所述第二展示状态以外的所有所述计算机发送暂停发送桌面图像的请求，以使处于所述第二展示状态的所述计算机根据所述请求信息提高传输分辨率和码率，同时使处于所述第二展示状态以外的所有所述计算机暂停发送桌面图像。
根据本实施例的无线传屏方法，每台计算机都会判断自身是否处于第二展示状态，如只有其中一台计算机检测到键盘输入信息和/或鼠标移动信息，表明正在操作该计算机的用户希望他人关注自己的计算机展示的内容，此时，由于该计算机处于第二展示状态，接收终端会将该计算机对应的分屏进行全屏显示，从而实现了自动对多分屏中的该分屏进行全屏显示，避免了复杂的操作，提升了交互体验。
此外，作为一个具体示例，本实施例提出的无线传屏方法还包括：
当根据所述第二反馈信息判断到没有或至少有两台所述计算机处于所述第二展示状态时，保持分屏显示所有所述计算机的桌面图像。

S302，当检测到自身处于第一展示状态时，向所述接收终端发送第一反馈信息，以使所述接收终端根据所述第一反馈信息判断到只有一台所述计算机处于所述第一展示状态时，将处于所述第一展示状态的所述计算机对应的分屏进行全屏显示。
此外，本实施例中，所述当检测到自身处于第一展示状态时，向所述接收终端发送第一反馈信息的步骤之后，所述方法包括：
接收所述接收终端发送的请求信息，所述请求信息包括提高传输分辨率和码率，同时接收所述接收终端发送的暂停发送桌面图像的请求，以使处于所述第一展示状态的所述计算机根据所述请求信息提高传输分辨率和码率，同时使处于所述第一展示状态以外的所有所述计算机暂停发送桌面图像。
本实施例中，所述第一反馈信息为所述计算机在所述第一预设时间内检测到窗口集合中位于最前端的桌面窗口发生切换时或窗口布局发生变化时所产生的消息；其中，所述窗口集合为所述计算机通过操作系统API枚举桌面上的桌面窗口后所获取到窗体大小大于桌面三分之一的全部窗口。
此外，本实施例中的方法还包括：
对自身是否处于第二展示状态进行检测，并将检测结果发送至接收终端，所述第二展示状态为所述计算机在第二预设时间内检测到键盘输入信息和/或鼠标移动信息；
当检测到自身处于第二展示状态时，向所述接收终端发送第二反馈信息， 以使所述接收终端根据所述第二反馈信息判断到只有一台所述计算机处于所述第二展示状态时，将处于所述第二展示状态的所述计算机对应的分屏进行全屏显示。

当检测到自身处于第一展示状态时，向所述接收终端发送第一反馈信息，以使所述接收终端根据所述第一反馈信息判断到没有或至少有两台所述计算机处于所述第一展示状态时，保持分屏显示所有所述计算机的桌面图像。请参阅图4，本发明第四实施例提出的无线传屏方法，应用于接收终端和与所述接收终端同时进行无线传屏的至少两台计算机，本实施例中，接收终端以会议平板为例进行说明，其中，所有的计算机和会议平板均安装了相应的传屏软件，同时所有的计算机和会议平板在同一个无线网络中，能够进行现有技术中的常规的无线传屏，且每台所述计算机的桌面图像分别显示在所述接收终端的对应分屏中，本实施例提出的无线传屏方法至少包括以下步骤：
S401，每台所述计算机均对自身是否处于展示状态进行检测，所述展示状态包括第一状态和/或第二状态，所述第一状态为在第一预设时间内检测到键盘输入信息和/或鼠标移动信息，所述第二状态为在第二预设时间内检测到桌面图像发生变化；

S405，全屏显示的分屏对应的计算机在第三预设时间之后，继续判断自身是否处于所述展示状态，若是，则所述接收终端保持全屏状态，若否，则所述接收终端恢复分屏状态。
其中，以所述第三预设时间为30秒为例进行说明，当其中一台计算机对应的分屏被会议平板全屏显示后，该计算机在30秒后，继续判断自身是否处于所述展示状态，若是，则会议平板继续保持全屏显示该计算机对应的分屏，若否，会议平板恢复开始分屏传屏的状态。
下面给出一个具体应用环境，会议中，四位设计师分别将自己笔记本上的设计稿以四分屏的形式投影在会议室的会议大平板上进行对比展示，讨论过程中需要对其中一些设计细节进行展示。设计师甲使用鼠标标示需要与会人员注意的细节或修改了正在展示的ppt里的内容，设计师甲的电脑根据上述方法判断自身处于展示状态，而其它电脑判断自身处于非展示状态，会议大平板统计到只有一台电脑处于展示状态，因此，会议大平板会自动将设计师甲的电脑的屏幕全屏显示。设计师甲讲解完毕30秒，设计师甲不再进行任何操作，此时，会议大平板会自动回到四分屏对比显示。可以理解的，如果有多个设计师同时对设计稿进行操作，则不会触发某个分屏的全屏显示。
