具体实施方式
下面将结合本公开实施例中的附图，对本公开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公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
附图中所示的流程图仅是示例说明，不是必须包括所有的内容和操作/步骤，也不是必须按所描述的顺序执行。例如，有的操作/步骤还可以分解、组合或部分合并，因此实际执行的顺序有可能根据实际情况改变。
应当理解，在此本公开说明书中所使用的术语仅仅是出于描述特定实施例的目的而并不意在限制本公开。如在本公开说明书和所附权利要求书中所使用的那样，除非上下文清楚地指明其它情况，否则单数形式的“一”、“一个”及“该”意在包括复数形式。
显示屏幕的远程共享，又可以称为显示屏幕的远程互动，可以为两个终端或者两个以上 终端的显示屏幕之间的共享与互动，屏幕的远程互动可以为不同终端的屏幕之间的屏幕共享，或者一个终端对另一个终端的屏幕进行的远程操作，其中，被共享屏幕的终端可以称为发送端或者共享端，相对应地，共享远程终端屏幕的终端可以称为接收端或者控制端。例如，远程会议中，一般会采取屏幕的远程互动，实现不同终端之间共享相同的视频画面。但是，传统的屏幕远程互动，一般只支持以一端屏幕的整体作为互动单位，即屏幕的可见区域即为屏幕的互动区域，缺乏对互动区域的限制，当发送端屏幕上存在不适宜共享的信息，或者当发送端被其它端进行远程控制时，发送端的所有信息将会暴露给远程控制端，以上两种情形，均存在发送端的不适宜共享的信息暴露的风险，无法保证发送端的信息安全。
本公开实施例提供了一种显示屏幕远程共享的处理方法、装置、系统、设备及存储介质。其中，处理方法可以应用于移动终端中，该移动终端可以为智能手机、智能手表、平板电脑、笔记本电脑、台式机电脑、个人数字助理和穿戴式设备等电子设备中，并可以在多个终端进行显示屏幕远程共享的业务场景下，采用本公开实施例提供的显示屏幕远程共享的处理方法进行互动。例如，在远程会议、客服系统远程指导、在线教育的互动、多端交互的远程办公场景、多人视频聊天或者多人游戏等多个终端的显示屏幕进行交互时，可以采用本公开实施例提供的显示屏幕远程共享的处理方法，实现对发送端选取的显示屏幕的共享。
面对不同终端之间的显示屏幕远程共享与互动，基于传统技术中发送端不适宜共享的信息存在暴露的风险，发明人提出本公开实施例的显示屏幕远程共享的处理方法，本公开实施例的核心思想为：多个终端进行显示屏幕共享时，发送端在显示屏幕内，选取屏幕共享区域，从而可控地可以将显示屏幕划分为屏幕共享区域与非屏幕共享区域，并将屏幕共享区域映射至远程终端进行共享，而非屏幕共享区域不与远程终端进行共享，从而能够灵活地确定是否将显示屏幕全部进行共享以及共享范围的大小，提高设置屏幕共享区域的灵活性，由于发送端能够选取显示屏幕的子集作为屏幕共享区域，可控地与远程终端进行显示屏幕的部分共享，而可以不将本端的显示屏幕的整体作为屏幕共享单位，能够实现对屏幕共享区域的限制，从而实现只共享屏幕共享区域上的信息，保证发送端的屏幕共享区域外的信息的安全。
下面结合附图，对本公开的一些实施例作详细说明。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
请参阅图1与图2，图1为本公开实施例提供的显示屏幕远程共享的处理方法的流程示意图，图2为本公开实施例提供的显示屏幕远程共享的处理方法的屏幕共享区域示意图。在多端交互的显示屏远程共享场景中，包含发送屏幕共享区域的发送端，及接收屏幕共享区域的远程终端(即接收端)，远程终端可以为多个，本公开实施例提供的显示屏幕远程共享的 处理方法应用于发送端。如图1所示，该方法包括以下步骤S11-S13。
S11、响应用户选取显示屏幕区域的第一操作，确定第一操作所对应的屏幕共享区域，其中，屏幕共享区域描述发送端共享给远程终端的显示屏幕的区域，屏幕共享区域为发送端的显示屏幕的子集。
其中，显示屏幕为终端设备用于显示内容的屏幕，显示屏幕可以采用单个显示屏(即单屏)作为显示内容的屏幕，或者显示屏幕也可以采用多个显示屏(即多屏)作为显示内容的屏幕，显示屏幕即为可视区域。
在一示例性实施例中，显示屏幕远程共享的实施过程中，包括两种终端，一种为本地终端，本地终端为共享的显示屏幕的提供者，可以称为共享显示屏幕的发送端，又可以称为共享端，另一种为远程终端，用于接收发送端发送的共享显示屏幕，远程终端又可以称为共享显示屏幕的接收端，接收端可以为多个，接收端可以为不同地点的不同终端。对于每个终端，例如对于发送端的显示屏幕，可以采取单屏或者多屏。对于单屏的显示屏幕，将屏幕上的设备坐标称为屏幕坐标(Screen coordinate)，以像素为单位来表示。对于多屏的显示屏幕，首先确定其中的一个显示屏为主屏，其它的显示屏为顺序描述的次屛或者副屏，以主屏的屏幕坐标为基准，按照次屛与主屏的位置，顺次确定每个副屏的坐标，从而得到多屏的屏幕坐标。
进行显示屏幕的远程共享时，用户可以在显示屏幕上通过鼠标拖动或者鼠标点击的方式选取一块区域作为屏幕共享区域，或者用户也可以通过设置显示屏幕的屏幕坐标的方式选取一块区域作为屏幕共享区域，屏幕共享区域描述发送端共享给远程终端的显示屏幕的区域，屏幕共享区域为发送端的显示屏幕的子集，即屏幕共享区域可以为显示屏幕的全部，屏幕共享区域也可以为显示屏幕的部分区域。对于单个显示屏的显示屏幕，屏幕共享区域可以为单个显示屏的全部显示区域，屏幕共享区域也可以为单个显示屏的部分显示区域。对于多个显示屏的显示屏幕，显示屏幕可以为单个显示屏的显示区域，显示屏幕也可以为跨显示屏的显示区域。例如，请参阅图2，对于包含显示屏A、显示屏B及显示屏C的显示屏幕，屏幕共享区域可以为单个显示屏所对应的显示区域或者其内部的部分区域，如屏幕共享区域1所示，为显示屏A内部的部分区域，屏幕共享区域也可以为跨显示屏的显示区域，如屏幕共享区域2所示，为跨显示屏B与显示屏C的跨显示屏的显示区域，且屏幕共享区域2包含显示屏B与显示屏C的各一部分区域。
响应用户选取显示屏幕区域的第一操作，确定第一操作所对应的显示屏幕上的至少两个屏幕坐标，并将所有屏幕坐标进行连线，得到多个屏幕坐标所围成的区域，即为屏幕共享区域，其中，屏幕共享区域描述发送端共享给远程终端的显示屏幕的区域，屏幕共享区域为发 送端的显示屏幕的子集。例如，以在显示屏幕上拖动鼠标的方式选取屏幕区域为例，基于显示屏幕的屏幕坐标，监测第一操作对应的起始屏幕坐标及终点屏幕坐标，并根据起始屏幕坐标及终点屏幕坐标，可以确定一个矩形区域，矩形区域即为第一操作所对应的屏幕共享区域。其中，选择屏幕可以定义在可执行程序、函数组、模块池(Executable programs、Function groups、Module pools)类型的程序中进行定义，由SELECT-OPTIONS,SELECTION-SCREEN and PARAMETERS语句在程序的全局声明区进行定义。
S12、根据屏幕共享区域，采集屏幕共享区域所对应的辅流，其中，辅流为屏幕共享流。
其中，辅流(Substream)，是单独为屏幕分享开启的一路上行视频流，例如在多人视频聊天、网络会议以及其它在线教育场景等多端远程交互场景下，需要同时发送两路视频流：一路是摄像头流，另一路是屏幕共享流，屏幕共享流即为辅流，是指第二条视频流，一般用于屏幕共享。
在一示例性实施例中，确定了屏幕共享区域后，基于屏幕共享区域的屏幕坐标，采集屏幕共享区域所对应的辅流。例如，可以根据屏幕共享区域的屏幕坐标，直接采集屏幕共享区域的屏幕坐标所对应的视频流，即得到辅流。也可以预先采集显示屏幕的视频流，并根据屏幕共享区域的屏幕坐标在显示屏幕的所有屏幕坐标中的位置，从显示屏幕的视频流中筛选出屏幕共享区域的视频流，得到辅流。
S13、将辅流发送至远程终端，以使远程终端根据辅流，显示辅流所对应的屏幕共享区域。
在一示例性实施例中，得到屏幕共享区域所对应的辅流后，将辅流发送至远程终端，远程终端根据辅流，显示辅流所对应的屏幕共享区域，从而将屏幕共享区域由发送端映射至远程终端，远程终端基于屏幕共享区域进行发送端的显示屏幕的共享。
本公开实施例，在多个终端进行显示屏幕共享时，通过将发送端的显示屏幕能够进行选取，得到屏幕共享区域，从而可控地可以将显示屏幕划分为屏幕共享区域与非屏幕共享区域，并将屏幕共享区域映射至远程终端进行共享，而非屏幕共享区域不与远程终端进行共享，从而能够灵活地确定是否将显示屏幕全部进行共享以及共享范围的大小，提高设置屏幕共享区域的灵活性，实现能够可控地、灵活地进行显示屏幕的部分远程共享，由于发送端能够选取显示屏幕的子集作为屏幕共享区域，可控地与远程终端进行显示屏幕的部分共享，从而能够不将本端屏幕的整体作为共享单位，以实现对屏幕共享区域的限制，达到只共享屏幕共享区域上的信息，仅共享必要的信息，能够保证发送端的屏幕共享区域外的信息的安全。
在一实施例中，请参阅图3与图4，图3为本公开实施例提供的显示屏幕远程共享的处 理方法的第一个子流程示意图，图4为本公开实施例提供的显示屏幕远程共享的处理方法中共享屏幕可控区域示例图。如图3所示，在该实施例中，确定第一操作所对应的屏幕共享区域之后，还包括步骤S14至S15。
S14、响应用户选取屏幕共享区域的子区域的第二操作，确定第二操作所对应的共享屏幕可控区域，其中，共享屏幕可控区域描述远程终端在屏幕共享区域内能够进行操作的区域，共享屏幕可控区域为屏幕共享区域的子集。
S15、将预设屏幕控制权限配置于共享屏幕可控区域，其中，预设屏幕控制权限描述发送端允许远程终端在共享屏幕可控区域进行操作的权限。
在一示例性实施例中，用户在屏幕共享区域内设置远程终端可以进行控制的区域时，用户在屏幕共享区域内进行子区域选取，用户进行子区域选取的操作为第二操作，响应用户选取屏幕共享区域的子区域的第二操作，发送端确定用户选取的屏幕共享区域的子区域所对应的屏幕坐标的范围，并将屏幕共享区域的子区域作为共享屏幕可控区域，其中，共享屏幕可控区域描述远程终端在屏幕共享区域内能够进行操作的区域，预设屏幕控制权限描述发送端允许远程终端在共享屏幕可控区域进行操作的权限，即发送端允许远程终端在发送端的共享屏幕可控区域进行操作的权限，共享屏幕可控区域为屏幕共享区域的子集，第二操作与第一操作类似。用户确定共享屏幕可控区域的大小后，发送端再将预设屏幕控制权限与共享屏幕可控区域对应关联起来，从而将预设屏幕控制权限配置于共享屏幕可控区域，以使共享屏幕可控区域具备被远程终端操作而进行控制的权限，预设屏幕控制权限包括远程终端通过鼠标或者键盘等输入设备对共享屏幕可控区域进行操作的权限，而屏幕共享区域内除共享屏幕可控区域外的显示区域不具备被远程终端操作而进行控制的权限，无法被远程终端进行操作而控制，其中，预设屏幕控制权限描述远程终端对共享屏幕可控区域进行操作的权限。请参阅图4，如图4所示，在图4所示的示例中，包括本地的发送端，及远程终端，远程终端包括接收端1、接收端2及接收端3，其中，接收端2又为控制端，即接收端2又为控制发送端的共享屏幕可控区域的终端，在发送端的显示屏幕上基于第一操作确定屏幕共享区域后，再在屏幕共享区域基于用户的第二操作确定发送端的可控区域(即共享屏幕可控区域)，再将可控区域与预设屏幕控制权限关联起来，从而将预设屏幕控制权限配置于可控区域，以使可控区域具备被远程终端操作而进行控制的权限，而屏幕共享区域内除可控区域外的其它显示区域不具备被远程终端操作而进行控制的权限，无法被远程终端进行操作而控制，而仅能进行视频图像显示，实现限制远程终端对共享屏幕的必要控制。
本公开实施例，通过在屏幕共享区域内设置远程终端可以进行控制的共享屏幕可控区域， 从而将屏幕共享区域进一步划分为共享屏幕可控区域与共享屏幕非可控区域，共享屏幕可控区域能够被远程终端进行控制，而共享屏幕非可控区域不能够被远程终端进行控制，让远程终端对共享的可视区域与可控区域可以不完全一致，从而能够灵活地确定是否将屏幕共享区域全部进行可控以及可控范围的大小，提高设置共享屏幕可控区域的灵活性，实现能够可控地、灵活地进行共享屏幕可控区域的部分远程可控，可以灵活适配各种应用场景的实际需要。由于发送端能够选取屏幕共享区域的子集作为共享屏幕可控区域，可控地与远程终端进行显示屏幕的部分可控，从而能够不将屏幕共享区域的整体作为可控单位，以实现对远程终端在屏幕共享区域进行操作的限制，达到只允许远程终端在共享屏幕可控区域上进行操作，能够进一步保证发送端的共享屏幕可控区域外的信息的安全。
在一示例性实施例中，确定第二操作所对应的共享屏幕可控区域之后，还包括：采用预设标注方式，将共享屏幕可控区域进行标注。
在一示例性实施例中，确定第二操作所对应的共享屏幕可控区域后，可以采用预设标注方式，将共享屏幕可控区域进行标注并显示，并将共享屏幕可控区域映射至远程终端，由于发送端的共享屏幕可控区域与控制端的共享屏幕可控区域为映射关系，在远程终端显示共享屏幕可控区域时，会以同样的预设标注方式将共享屏幕可控区域进行标注并显示，共享屏幕可控区域会突出地显示在远程终端的显示屏幕上，从而使远程终端的用户能够清楚地明确远程可控操作的屏幕区域，预设标注方式包括将共享屏幕可控区域的边框进行突出显示，或者将共享屏幕可控区域的区域整体进行突出显示，突出显示方式可以采取下述方式的至少一种：将边框进行加粗、将边框进行高亮显示，将边框的线条格式进行断线或者圆点等方式进行显示、将边框的颜色采取异于其它区域的颜色，以及将共享屏幕可控区域的区域整体进行高亮显示，将共享屏幕可控区域的区域整体的颜色采取异于其它区域的颜色。例如，请继续参阅图4，将发送端的可控区域映射至接收端2(即控制端)，在控制端显示发送端共享的可控区域(即控制端的可控区域)时，可以将控制端的可控区域的边框进行突出显示，例如，将控制端的可控区域的边框进行加粗、高亮或者采取异于屏幕其它区域的颜色进行突出显示，或者将控制端的可控区域的区域整体进行高亮或者颜色采取异于其它区域的颜色进行突出显示。
本公开实施例，通过采用预设标注方式，将共享屏幕可控区域进行标注并显示在远程终端，从而将共享屏幕可控区域异于同屏幕的其它区域突出地进行显示，便于远程终端的用户能够清楚地明确进行远程可控操作的屏幕范围，能够提高共享屏幕可控区域的操作便利性与可控操作的控制效率。
在一示例性实施例中，将预设屏幕控制权限配置于共享屏幕可控区域之后，还包括：将 共享屏幕可控区域的屏幕控制权授予远程终端，并将共享屏幕可控区域映射至远程终端。
在一示例性实施例中，在多终端进行显示屏幕远程共享的过程中，发送端确定共享屏幕可控区域后，可以通过发送端指定一个远程终端的方式，也可以通过远程终端对共享屏幕可控区域的屏幕控制权进行申请并经发送端确认的方式，将共享屏幕可控区域的屏幕控制权授予远程终端(即控制端)，同时，将共享屏幕可控区域映射至控制端，以使控制端基于映射过去的共享屏幕可控区域进行共享屏幕可控区域的控制操作。本公开实施例，通过将共享屏幕可控区域的屏幕控制权授予远程终端，并将共享屏幕可控区域映射至控制端，以实现控制端对共享屏幕可控区域的可控，从而将控制端对发送端显示屏幕的可控操作限制在共享屏幕可控区域内，能够保证发送端的共享屏幕可控区域外的信息的安全。
在一实施例中，请参阅图5，图5为本公开实施例提供的显示屏幕远程共享的处理方法的第二个子流程示意图。如图5所示，在该实施例中，将共享屏幕可控区域映射至远程终端之后，还包括：S51、接收远程终端的远端控制指令，其中，远端控制指令描述远程终端对映射在其上的共享屏幕可控区域进行操控的指令；S52、将远端控制指令转换成本地的模拟控制指令，并执行模拟控制指令，以对发送端的共享屏幕可控区域进行操作。
在一示例性实施例中，远程终端获取共享屏幕可控区域的控制权限，并在共享屏幕可控区域映射在其显示屏幕上后，对映射在其上的共享屏幕可控区域，可以通过手势、语音、鼠标或者键盘等终端设备的输入方式进行操控，对应地，产生共享屏幕可控区域的远端控制指令，并将远端控制指令返回至发送端，发送端接收远端控制指令，并将远端控制指令转换成本地的模拟控制指令，例如将远程终端的鼠标控制指令模拟成本地的鼠标控制指令，将远程终端的键盘控制指令模拟成本地的键盘控制指令等，并执行模拟控制指令，相当于本地的键盘或者鼠标等输入设备在共享屏幕可控区域的控制操作，实现远程终端对发送端的共享屏幕可控区域进行控制操作。
本公开实施例，通过远程终端对映射在其上的共享屏幕可控区域进行操控，产生对应的远端控制指令，并将远端控制指令发送至发送端，发送端将远端控制指令转换成本地的模拟控制指令，并执行模拟控制指令，以对发送端的共享屏幕可控区域进行操作，从而实现远程终端对发送端的共享屏幕可控区域的可控操作，从而将远程端对发送端显示屏幕的可控操作限制在共享屏幕可控区域内，既能够实现远程终端对发送端的显示屏幕的控制操作，又能够保证发送端的共享屏幕可控区域外的信息的安全。
在一实施例中，请参阅图6，图6为本公开实施例提供的显示屏幕远程共享的处理方法的第三个子流程示意图。如图6所示，在该实施例中，接收远程终端发送的远端控制指令， 包括步骤S61至S64。
S61、接收远程终端发送的初始远端控制指令；S62、判断初始远端控制指令是否为预设异常控制指令；S63、若初始远端控制指令不为预设异常控制指令，将初始远端控制指令作为远端控制指令；S64、若初始远端控制指令为预设异常控制指令，将初始远端控制指令过滤掉。
在一示例性实施例中，对远程终端的可控操作进行限制，来避免远程终端的可控操作的权限过大对发送端带来消极影响，例如，对于远程终端传送的切屏与锁屏对发送端有较大影响的快捷键指令，在发送端不能进行执行，同时，共享屏幕可控区域外的操作指令，例如，由于共享屏幕可控区域为屏幕共享区域的子集，若共享屏幕可控区域小于屏幕共享区域，则共享屏幕可控区域外且在屏幕共享区域内的区域也是不允许远程终端进行控制操作的，远程终端对上述区域的操作指令也不能执行。基于此，预先设置异常控制指令(即预设异常控制指令)，以对远程终端的控制操作进行限制。预设异常控制指令的设置可以采取以下两种方式进行：1)设置指令黑名单。指令黑名单中的控制指令将不能被执行，若远程终端发送的远端控制指令为指令黑名单中的指令，远端控制指令将不被执行，若远程终端发送的远端控制指令不为指令黑名单中的指令，远端控制指令将被执行；2)设置指令白名单。指令白名单中的控制指令将被执行，若远程终端发送的远端控制指令为指令白名单中的指令，远端控制指令将被执行，若远程终端发送的远端控制指令不为指令白名单中的指令，远端控制指令将不被执行。
基于上述预设异常控制指令的设置，远程终端发送初始远端控制指令后，发送端接收初始远端控制指令，并可以基于预设指令黑名单或者预设指令白名单，判断初始远端控制指令是否为预设异常控制指令，从而对初始远端控制指令的有效性进行验证，若初始远端控制指令不为预设异常控制指令，将初始远端控制指令作为远端控制指令，并执行远端控制指令，若初始远端控制指令为预设异常控制指令，将初始远端控制指令过滤掉，不执行初始远端控制指令。
本公开实施例，通过发送端对远程终端发送的远端控制指令进行有效性验证，若远程终端发送的远端控制指令为有效的，将被执行，若远程终端发送的远端控制指令不为有效的，则远程终端发送的远端控制指令，将不被执行，可以避免远程终端的可控操作的操作权限过大或者被滥用，实现限制远程终端对共享屏幕的必要控制，从而进一步保证发送端的显示屏幕的可控操作的安全性与信息的安全。
在一示例性实施例中，确定第二操作所对应的共享屏幕可控区域之后，还包括：响应用户调整共享屏幕可控区域的第三操作，调整共享屏幕可控区域的大小；和/或者，确定第一操 作所对应的屏幕共享区域之后，还包括：响应用户调整屏幕共享区域的第四操作，调整屏幕共享区域的大小。
在一示例性实施例中，在确定屏幕共享区域，或者确定共享屏幕可控区域后，可以根据实际屏幕共享的需要，由用户调整屏幕共享区域的大小，或者调整共享屏幕可控区域的大小，例如，通过鼠标拖动的方式，响应用户调整共享屏幕可控区域的第三操作，将共享屏幕可控区域变大或者缩小，或者，响应用户调整屏幕共享区域的第四操作，将屏幕共享区域变大或者缩小。
本公开实施例，通过用户动态地调整屏幕共享区域的大小或者调整共享屏幕可控区域的大小，既能够实现远程终端对屏幕共享区域的共享或者对共享屏幕可控区域的控制，又能够保证屏幕共享区域外的信息的安全性或者共享屏幕可控区域外的信息操控的安全性。
在一实施例中，确定第一操作所对应的屏幕共享区域之后，还包括：响应用户对屏幕共享区域进行权限配置的第五操作，将预设屏幕共享权限配置于屏幕共享区域，其中，预设屏幕共享权限描述远程终端对屏幕共享区域进行共享的权限。
