具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
在下述介绍中，术语“第一”、“第二”仅为用于描述的目的，而不能理解为指示或暗示相对重要性。下述介绍提供了本申请的多个实施例，不同实施例之间可以替换或者合并组合，因此本申请也可认为包含所记载的相同和/或不同实施例的所有可能组合。因而，如果一个实施例包含特征A、B、C，另一个实施例包含特征B、D，那么本申请也应视为包括含有A、B、C、D的一个或多个所有其他可能的组合的实施例，尽管该实施例可能并未在以下内容中有明确的文字记载。
下面的描述提供了示例，并且不对权利要求书中阐述的范围、适用性或示例进行限制。可以在不脱离本申请内容的范围的情况下，对描述的元素的功能和布置做出改变。各个示例可以适当省略、替代或添加各种过程或组件。例如所描述的方法可以以所描述的顺序不同的顺序来执行，并且可以添加、省略或组合各种步骤。此外，可以将关于一些示例描述的特征组合到其他示例中。
交互平板的硬件部分由触控显示模组、整机模块(包括控制器)等部分所构成，由整体结构件结合到一起，其中触控显示模组包括显示屏、触控组件和背光灯组件，背光灯组件用于为显示屏提供背光光源，显示屏一般采用液晶显示装置，用于进行画面展示，触控组件设置在显示屏上或者设置在显示屏前端，用于采集用户的触控操作所产生的触控数据，并将采集的触控数据发送到整机模块进行处理。
在实际使用中，交互平板的显示屏上显示画面数据，当用户通过手指或者触控笔等触控物体点击显示屏上显示的内容，例如点击显示屏上显示的图形按钮时，交互平板的触控组件将采集到触控数据，从而触控组件将该触控数据转换为触控点的坐标数据后发送到整机模块，或者将该触控数据发送到整机模块处由整机模块转换为触控点的坐标数据，整机模块获得触控点的坐标数据后，发送到相应的程序实现相应的控制操作，驱动显示屏显示内容发生变化，实现多样化的显示、操作效果。
从技术原理来区别触摸组件，可以分为五个基本种类；矢量压力传感技术触摸组件、电阻技术触摸组件、电容技术触摸组件、电磁技术触摸屏、红外线技术触摸组件、表面声波技术触摸组件。按照触摸组件的工作原理和传输信息的介质，可以把触摸组件分为四个种类：电阻式、电容感应式、电磁感应式、红外线式以及表面声波式。
本申请实施例中，交互平板相当于一个带整机模块的具有触控功能的显示屏，整机模块是交互平板的内置模块，不包含主控模块，其内部运行着一个低性能的Android系统，整机模块主要实现交互平板的显示处理及触控数据处理功能。整机模块的硬件配置较低，除了配置操作系统和基础的处理软件(例如白板书写软件、批注应用软件)外，不支持安装其它应用软件。交互平板如果需要实现其他功能，需要接入主控模块，通过在主控模块上安装相关应用软件来实现对应的功能，例如需要进行文件的展示，则需要在主控模块上 安装相关的展示软件，需要实现视频会议功能，则需要在主控模块上安装视频会议软件，等等。主控模块是交互平板上的一个可插拔(OPS，Open Pluggable Specification)模块，交互平板上运行的应用软件都安装在主控模块上。主控模块运行的可以是Windows、高性能Android等操作系统，例如主控模块可以采用PC模块、高性能Android模块等，其可以理解为一台电脑。
交互平板至少包括Android通道、主机通道和HDMI通道等信号源通道，这些信号源通道用于接收不同的信号源的输入信号，从而交互平板可以在不同的信号源通道之间切换，以呈现不同信号源提供的媒体内容。其中，Android通道为交互平板的整机模块自身的工作通道，用于呈现整机模块的媒体内容。主机通道所接入的信号源为主机模块，从而主机通道用于呈现交互平板的主机模块所输入的媒体数据。HDMI通道用于呈现通过交互平板的HDMI接口所接入的信号源的媒体数据。另外，交互平板处于主机通道或者HDMI通道时，交互平板的显示屏实际上会显示两个系统的画面，一个是Android通道的画面，另一个是主机通道或者HDMI通道的画面，Android通道的画面会存在部分透明区域，从而主机通道或者HDMI通道的画面显示在该透明区域中，从而最后呈现的显示画面是两个通道的显示画面。例如，Android通道的画面是侧边栏，则Android通道的画面除了侧边栏的显示区域外，其它区域全是透明区域，从而主机通道或者HDMI通道的显示画面可以显示在透明区域中，最后给用户呈现的结果就是交互平板显示主机通道或者HDMI通道的画面，并且在该画面上叠加显示有Android通道的侧边栏。具体的，整机模块会预先设定主机通道或者HDMI通道等通道的显示画面的区域大小，从而整机模块在接收到触控组件的触控数据时，会将处于该预先设定的区域内的触摸数据发送到主机通道或者HDMI通道进行响应。
更具体的，整机模块包括主控板卡，主控板卡上设置有主控芯片、主控芯片的电源电路等外围电路，还设置有多个用于进行通信的通信接口，多个通信接口均与主控芯片连接。多个通信接口具体包括串行接口、USB接口、HDMI接口、Type-C接口和/或触摸线端口(Touch out端口)等。整机模块通过串行接口与主控模块连接，USB接口、HDMI接口等接口与其它设备或终端进行通信连接，从而接收不同的信号源的输入信号，形成相应的信号源通道。例如，整机模块通过串行接口与主控模块连接，形成主机通道，从而可以接收并呈现主机通道发送的媒体内容，或者通过HDMI接口与外接设备连接，形成HDMI通道，从而呈现外接设备所输入的媒体数据。
主控芯片具有第一功能单元和第二功能单元一共两个独立的功能单元，第一功能单元安装有Android系统，第二功能单元用于进行交互平板的信号源通道的切换控制。第一功能单元和第二功能单元可以通过运行在同一主控芯片上的不同代码来实现，也可以分别通过两个主控芯片上的不同代码来实现(此时，主控芯片的数量为两个)。
当交互平板处于不同的信号源通道时，整机模块对触控数据具有不同的处理方式，当交互平板的信号源通道为Android通道时，表示交互平板处于整机模块自身的工作通道，用于呈现整机模块的媒体内容。此时，整机模块接收到触控组件发送的触控数据时，由Android系统进行触控数据的兼容性处理(通过兼容性处理，将不同类型的触摸组件产生的触控数据处理成统一格式的数据，从而Android系统的处理进程可以进行识别和响应)，并进行触控数据的操作响应，执行对应的操作。当交互平板的信号源通道为主机通道时，整机模块接收到触控组件发送的触控数据时，首先由Android系统进行触控数据的兼容性处理，然后Android系统根据预先设定的主机通道的显示画面的区域大小，将在主机通道的显示画面区域内产生的触控数据通过第二功能单元转发到主机通道进行响应。当交互平板的信号源通道为HDMI通道时，整机模块接收到触控组件发送的触控数据时，首先由Android系统进行触控数据的兼容性处理，并进行触控数据的操作响应，执行对应的操作。 然后Android系统根据预先设定的HDMI通道的显示画面的区域大小，将在HDMI通道的显示画面区域内产生的触控数据通过第二功能单元转发到触摸线端口(Touch out端口)，由触摸线端口(Touch out端口)的外接设备进行响应。
图1为本申请相关技术中的内外网隔离的两台交互平板连接示意图，图1中，第一终端10和第二终端20均为本申请实施例中的交互平板，第一终端10仅连接局域网，第二终端20连接互联网。第一终端10包括第一主控模块11和第一整机模块12，第二终端20包括第二主控模块21、第二整机模块22和第二触控屏23。第一终端10的用于展示文件的应用软件安装在第一主控模块11上，因此，HDMI采集卡30连接在第一主控模块11和第二主控模块21之间，用于将第一终端10中的画面数据传输至第二终端20。HDMI采集卡30采集第一主控模块11的画面数据后，发送到第二主控模块21，以采集卡窗口的方式进行显示，从而第二主控模块21安装的软件例如视频会议软件，可以通过互联网将包含采集卡窗口的显示画面共享给其他外部终端，实现将第一终端10的画面数据通过互联网发送到其他外部终端进行画面共享的目的。
这种情况下，由于HDMI采集卡30是将第一主控模块11的画面数据发送到第二主控模块21进行显示，因此，第二终端20处于主机通道下，这种情况下，第二整机模块22将接收到的触控数据发送到第二主控模块21进行响应，无法将第二终端20的触控数据发送到第一终端10，即无法实现触摸回传功能。
如果要实现触摸回传功能，则需要将第一主控模块11的画面数据发送到第二整机模块22进行显示，但由于第二整机模块22的硬件配置比较低，除了配置操作系统和基础的处理软件(例如白板书写软件、批注应用软件)外，不支持安装应用软件。则这种情况下虽然能实现触摸回传功能，但是无法实现将第一终端10的画面数据通过互联网发送到其他外部终端进行画面共享的目的。
因此的，目前相关技术中，内外网隔离的第一终端10和第二终端20之间的连接方式，无法同时满足将第一终端10的画面数据通过互联网进行画面共享，和将第二终端20的触控数据发送到第一终端10的需求。
请参见图2，图2是本申请实施例提供的一种数据传输系统的结构示意图。如图2所示，该数据传输系统可以包括第一终端10、第二终端20和HDMI采集卡30。
其中，HDMI采集卡30包括目标HDMI端口301和目标USB端口302，第一终端10包括第一主控模块11和第一整机模块12，第一主控模块11包括第一HDMI端口111和第一USB端口112，第二终端20包括第二主控模块21、第二整机模块22和第二触控屏23，第二整机模块22分别与第二主控模块21和第二触控屏23连接，第二主控模块21包括第二HDMI端口211和第二USB端口212，第二整机模块22包括第三HDMI端口221和触摸线端口222，第一USB端口112与触摸线端口222相连接，第一HDMI端口111与目标HDMI端口301连接，目标USB端口302与第二USB端口212连接，第二HDMI端口211与第三HDMI端口221连接，第一终端10仅连接局域网，第二终端20连接互联网。
其中，如图3所示，第一主控模块11上的第一HDMI端口为HDMI OUT端口。第二主控模块21上的第二HDMI端口为HDMI OUT端口，第二整机模块22上的第三HDMI端口221为HDMI IN端口，第二整机模块上的触摸线端口为TOUCH端口。
如前所述，传统技术中，交互平板的主控模块与整机模块之间是通过串行接口连接的，从而通过串行接口实现数据交互通信，实现相关交互功能。本实施例中，将第二主控模块21上的HDMI OUT端口连接到第二整机模块22上的HDMI IN端口，构建了第二主控模块21和第二整机模块22之间新的通信链路，从而第二整机模块22可以通过HDMI通道进行数据交互，以实现主控模块的数据传输到整机模块的HDMI IN端口，从而可以将主 机通道显示的部分或全部画面发送到HDMI通道进行显示。通过将第二整机模块22的触摸线端口(Touch out端口)连接到第一终端的第一USB端口112，再结合HDMI通道工作模式下，触摸线端口(Touch out端口)可以实现触摸数据输出的特性，可以实现第二终端的触摸数据回传到第一终端进行响应。
第一终端10和第二终端20的屏幕页面上左边或右边置顶等地方可以运行有侧边栏应用程序，点击侧边展开后，可以有一些高频的按钮，比如“返回”、“主页”，如图4所示。在主机通道下显示的是主机侧边栏，在HDMI通道下显示的是整机侧边栏。通过监听用户对侧边栏按键的点击操作来实现HDMI通道与主机通道间的切换。
在一实施例中，第二终端20在启动后，首先确定所述第二终端20的系统模式；若所述系统模式为非复制屏模式，则将所述系统模式切换至复制屏模式。在复制屏模式下可在主机通道以及HDMI通道之间进行切换。
第一终端10和/或第二终端20包括但不限于：个人电脑、交互平板、手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备等。在不同的网络中用户终端可以叫做不同的名称，例如：用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置、蜂窝电话、无绳电话、个人数字处理(personal digital assistant，PDA)、5G网络或未来演进网络中的终端设备等。
为描述方便，本申请实施例以第一终端和第二终端均为交互平板为例进行描述。
需要说明的是，上述各模块中的各端口数量仅作为示例进行解释说明，本申请实施例对各端口的具体数量不作限定。
通过上述连接方式，通过一HDMI采集卡，一端接第一终端10的HDMI OUT端口，一端接第二终端20主控模块的USB端口，以实现第一终端的画面可以窗口化的方式在第二终端的主控画面上显示，再通过一条HDMI线，将第二终端20的第二主控模块21的HDMI OUT接入到第二终端20的第二整机模块22的HDMI IN上，以实现主控模块的数据传输到整机模块的HDMI IN端口，从而可以将主机通道的部分或全部画面发送到HDMI通道进行显示，最后，再使用一条Touch触摸线将第一终端10与第二终端20相互连接起来，以实现触摸可回传的功能。解决了用户在局域网条件下，内部的终端可以通过HDMI采集卡+HDMI线+TOUCH线，结合特定软件实现的方式，满足用户在多个大屏下主控画面触摸回传的需求，且可以实现将第一终端10的画面数据通过第二终端20连接的互联网进行画面共享的功能。
接下来结合图1-图4示出的数据传输系统介绍本申请实施例提供的数据传输方法。
参见图5，图5是本申请实施例提供的一种数据传输方法的流程示意图。本实施例主要强调实现触摸回传的过程，方法包括：
S101、HDMI采集卡通过目标HDMI端口接收第一主控模块发送的第一画面数据后，通过目标USB端口将第一画面数据发送至第二主控模块的第二USB端口；
HDMI采集卡在本申请实施例中可以理解为具有高清晰度多媒体端口的采集卡。采集卡主要是用于捕获外界光电、视频、音频等模拟信号并将其数字化导入计算机进行数字处理的捕获设备，主要包括图像采集卡、视频采集卡、音频采集卡(比如声卡)、数据采集卡等。HDMI采集卡具有HDMI端口与USB端口两种不同型号的端口，通过这两个端口可以将两个终端进行连接，HDMI采集卡通过HDMI端口接收其中一终端的HDMI数据格式的数据，并进行格式转换后，将HDMI格式的数据转换为USB数据格式的数据后发送到另一终端。
第一主控模块在本申请实施例中可以理解为第一终端上搭载的外接系统
模块，例如PC模块或者高性能Android模块，主要用于进行视频相关数据的传输。
第二主控模块在本申请实施例中可以理解为第二终端上搭载的外接系统模块，同样也可以是PC模块或者高性能Android模块，主要用于进行视频相关数据的传输。
第一画面数据在本申请实施例中可以理解为第一终端所显示的画面对应的数据信息。
具体的，第一主控模块采集第一终端的第一画面数据，并通过第一HDMI端口将第一画面数据发送到HDMI采集卡，HDMI采集卡通过目标HDMI端口获取到第一画面数据，并将第一画面数据通过目标USB端口发送至第二终端上第二主控模块的第二USB端口，以此将第一终端的第一画面数据传输至第二终端上。需要注意，这里，HDMI采集卡通过目标HDMI端口获取到的第一画面数据是第一主控模块编码成HDMI格式的数据，HDMI采集卡将HDMI数据格式的数据进行格式转换，将第一画面数据由HDMI数据格式转换成USB数据格式的数据后，通过目标USB端口发送到第二主控模块，即从目标HDMI端口接收到的第一画面数据以HDMI数据格式传输，通过目标USB端口发送的第一画面数据以USB数据格式传输，从而第二主控模块接收到USB数据格式的第一画面数据后，可以根据第二主控模块的设置进行相应形式的显示，例如作为窗口进行显示、全屏显示，或者弹出一个窗口，供用户确认是否进行显示等。
S102、第二主控模块通过第二USB端口接收到HDMI采集卡所采集的第一终端的第一画面数据后，第二终端在主机通道工作模式下显示采集卡窗口，并在采集卡窗口内显示第一画面数据，第一画面数据包括显示在第一终端的显示画面的画面数据；
采集卡窗口是在第二终端的显示画面上的一个窗口，该窗口用于显示第一画面数据。在本申请实施例中，采集卡窗口是由第二主控模块上运行的一个独立程序所生成的，这里，可以将该独立程序称为采集卡窗口程序。采集卡窗口程序运行在第二主控模块上，可以接收第一画面数据，从而可以将接收到的第一画面数据显示在采集卡窗口中。
具体的，第二主控模块通过第二USB端口接收到HDMI采集卡传输的USB数据格式的第一画面数据后，将在第二终端的当前显示画面上显示采集卡窗口，并在采集卡窗口中显示第一画面数据，以此在第二终端上显示的第一终端的画面内容。此时，第二终端处于主机通道模式，用于显示第二主控模块的画面数据。即，实际显示效果是在第二主控模块的画面上叠加显示采集卡窗口，然后在采集卡窗口中显示第一画面数据。例如第二主控模块原本运行的是视频会议软件，显示的是视频会议画面，则第二主控模块通过第二USB端口接收到第一画面数据后，在视频会议画面上显示采集卡窗口，在采集卡窗口内显示第一画面数据。从而用户看到的画面是在第二终端的画面上，以窗口的形式显示第一终端的画面数据。
S103、第二主控模块确认对采集卡窗口进行全屏显示时，向第二整机模块发送通道切换信息，并将第一画面数据通过第二HDMI端口(HDMI out端口)发送到第二整机模块的第三HDMI端口(HDMI in端口)；
通道在本申请实施例中可以理解为用于访问显示器存储器以获取显示器中EEPROM的EDID格式数据，从而确定显示器的显示属性(如分辨率、纵横比等)信息的数据通道，能够将显示器的物理数据直接传输给终端。
在本申请实施例中，当用户对采集卡窗口进行全屏显示操作时，用户操作将会触发相应的操作信号，第二主控模块确认接收到进行全屏显示的操作信号，则向第二整机模块发送通道切换信息，同时，第二主控模块将第一画面数据发送至第二整机模块。其中，进行全屏显示操作的方式可以包括点击侧边栏上的预设控件例如点击全屏显示按钮、通过菜单选择全屏显示、语音控制等方式。
其中，第二主控模块与第二整机模块通过串行接口进行连接，第二主控模块将通道切 换信息通过串行接口传输到第二整机模块。
S104、第二整机模块接收到通道切换信息后，将信号源通道由主机通道切换为HDMI通道，并接收第二主控模块发送的第一画面数据后，第二终端在HDMI通道工作模式下显示所述第一画面数据；
具体的，第二整机模块在接收到通道切换信息后，从主机通道切换为HDMI通道，实现通道切换，同时，还接收到第一画面数据。由于第二整机模块与第二触控屏连接，第二整机模块将第一画面数据发送至第二触控屏进行显示，以此实现在全屏模式下对第一画面数据的显示以及通道的切换。
S105、第二整机模块获取第二触控屏的第一触摸操作数据后，并通过触摸线端口将第一触摸操作数据发送至第一终端的第一USB端口；
在HDMI通道下，用户可以在第二终端的第二触控屏上进行触摸操作，当用户在第二触控屏上输入触摸信息后，第二整机模块获取该触摸操作的第一触摸操作数据，那么在第二终端上响应该触摸操作，例如生成触摸轨迹、响应操作控件等。同时，第二终端与第一终端通过触摸线连接，那么第二整机模块通过触摸线将该第一触摸操作数据发送至第一终端的第一主控模块，以在第一终端上也进行响应。
其中，触摸操作可以包括书写操作、调用图形控件插入图形操作、调用调节控件对显示画面进行调节操作等。例如，用户在第二终端的第二触控屏上对显示画面进行书写标记、形成圈选轨迹等，此时，由于第二整机模块通过触摸线将该第一触摸操作数据发送至第一终端的第一主控模块，因此第一终端也可以在其显示画面上进行书写标记、形成圈选轨迹等。
S106、第一终端通过第一USB端口接收到第一触摸操作数据后，执行第一触摸操作数据对应的触摸操作，并更新第一终端的显示画面。
第一终端通过第一主控模块接收第二终端发送的第一触摸操作数据，并响应该第一触摸操作数据对应的触摸操作，同时对显示画面进行更新，以呈现和第二终端相同的响应效果，以此实现触摸回传，进而实现用户通过第二终端的触摸操作来对第一终端上的画面进行操作控制的过程。
在本申请一个或多个实施例中，在第二终端的第二主控模块获取到第一终端的画面数据后，以采集卡窗口形式显示该画面数据，当第二主控模块确认对采集卡窗口进行全屏显示时，向第二整机模块发送通道切换信息，并将第二主控模块的画面数据通过第二HDMI端口发送到第二整机模块的第三HDMI端口，第二整机模块接收到通道切换信息后，将信号源通道切换为HDMI通道，从而可以通过HDMI通道显示画面数据，那么在HDMI通道下，第二整机模块获取第一触摸操作数据后，将该第一触摸操作数据回传至第一主控模块，从而执行第一触摸操作数据对应的触摸操作，并更新第一终端的显示画面，实现触摸回传功能，且可以实现将第一终端的画面数据通过互联网进行画面共享的功能。
参见图6，图6是本申请实施例提供的又一种数据传输方法的流程示意图。本实施例主要强调在进行视频会议时实现触摸回传过程。如图6所示，方法包括：
S201、HDMI采集卡通过目标HDMI端口接收第一主控模块发送的第一画面数据后，通过目标USB端口将画面数据发送至第二主控模块的第二USB端口；
S202、第二主控模块通过第二USB端口接收到HDMI采集卡所采集的第一终端的第一画面数据后，第二终端在主机通道工作模式下显示采集卡窗口，并在采集卡窗口内显示第一画面数据，第一画面数据包括显示在第一终端的显示画面的画面数据；
S201-S202具体可参见S101-S102，此处不再赘述。
S203、第二主控模块确认接收到对显示画面的共享操作后，将当前显示画面的第二 画面数据发送至一会议终端进行显示，会议终端与第二主控模块通过互联网连接。
其中，接收到的对显示画面的共享操作，可以为被动接收，即第二主控模块通过视频会议软件接收到会议终端发送的显示画面的共享请求，并接收到用户对共享请求进行确认的操作后，确认接收到对显示画面的共享操作，具体而言，可以是其他会议终端邀请用户进行视频会议时用户点击视频会议加入按键所进行的加入会议操作。也可以为主动发起，即第二主控模块接收到用户在视频会议软件上发起的对显示画面的共享指令后，确认接收到对显示画面的共享操作。具体而言，可以是用户点击屏幕上的视频会议软件中的发起按键并选择参会终端。
S204、第二主控模块确认对采集卡窗口进行全屏显示时，向第二整机模块发送通道切换信息，并将第一画面数据通过第二HDMI端口发送到第二整机模块的第三HDMI端口；
需要注意，对于主控模块来说，对采集卡窗口进行全屏显示，则表示主控模块实际上显示的画面是采集卡窗口的全屏显示窗口，因此，主控模块发送到会议终端进行显示的第二画面数据是全屏显示状态的采集卡窗口中的数据，即会议终端也会全屏显示采集卡窗口中的内容，实现与第一终端的显示画面的一致。
S205、第二整机模块接收到通道切换信息后，将信号源通道切换为HDMI通道，并接收第二主控模块发送的第一画面数据后，通过第二触控屏显示第一画面数据；
S206、第二整机模块获取第二触控屏的第一触摸操作数据后，执行相应的触摸操作，并通过触摸线端口将第一触摸操作数据发送至第一主控模块的第一USB端口；
S207、第一终端通过第一USB端口接收到第一触摸操作数据后，执行第一触摸操作数据对应的触摸操作，并更新第一终端的显示画面。
执行第一触摸操作数据对应的触摸操作，具体可以为：基于第一触摸操作，绘制相应的书写笔迹；或，基于第一触摸操作，调用相应的应用控件。
触摸操作可以是书写操作，或者调用图形控件插入图形操作、调用调节控件对显示画面进行调节操作等。例如，用户在第二终端的第二触控屏上对显示画面进行书写标记、形成圈选轨迹等，此时，由于第二整机模块通过触摸线将该第一触摸操作数据发送至第一终端的第一主控模块，因此第一终端也可以在其显示画面上进行书写标记、形成圈选轨迹等。
S204-S207具体可参见S103-S106，此处不再赘述。
S208、第二整机模块接收到第二触控屏的第二触摸操作数据后，将第二触摸操作数据发送至第二主控模块；
第二触摸操作可以是书写操作。
由于第二整机模块分别与第二触控屏以及第二主控模块连接，当用户在第二触控屏输入第二触摸操作后，第二整机模块接收第二触控屏发送的第二触摸操作对应的第二触摸操作数据，然后发送至第二主控模块。
S209、第二主控模块接收到第二触摸操作数据后，显示相应的书写笔迹，并将第二触摸操作数据发送至会议终端，使得会议终端根据第二触摸操作数据显示相应的书写笔迹。
第二主控模块接收该第二触摸操作数据后进行相应的书写笔记，同时将该数据同步发送至会议终端，那么在会议终端上也显示相同的书写笔记，实现远程控制及同步显示的效果。
S210、第二主控模块接收会议终端发送的第三触摸操作数据后，执行第三触摸操作数据对应的触摸操作，并更新HDMI通道的显示画面。
用户也可以在会议终端上进行触摸操作，那么会议终端将相应的第二触摸操作数据发送至第二主控模块，第二主控模块响应相应的操作，并同步更新显示画面。具体的，第二 主控模块接收会议终端发送的第二触摸操作数据后，执行第二触摸操作数据对应的触摸操作，在一个透明图层上生成对应的触摸笔迹，从而将带有触摸笔迹的透明图层的数据也发送到第二整机模块，由整机模块将该数据与第一画面数据叠加显示，实现HDMI通道的显示画面的更新，表现为在第一画面数据上显示了触摸笔迹，还原了会议终端的操作。从而可以在画面共享的过程中，接收到用户在会议终端进行的触摸操作，并形成相应的笔迹数据。应用在医疗场景中，可以实现接收远程会诊专家的专家标注数据，使得本地的医生更清楚地看到会诊意见。从而本方案不仅可以将内网数据通过外网终端共享到其它会议终端，还可以接收并显示其它会议终端的笔迹数据。
S211、当第二整机模块确认接收到退出HDMI通道的操作指令时，将信号源通道切换为主机通道，并通过主机通道接收第二主控模块发送的当前显示画面的第二画面数据后，显示第二画面数据；
第二整机模块调用显示整机侧边栏的端口，并显示整机侧边栏；当第二整机模块接收到针对整机侧边栏的预设控件的点击操作，则确认接收到退出HDMI通道的操作指令，此时退出HDMI通道，并切换为主机通道，而第二主控模块与第二整机模块通过串行接口连接，第二主控模块将第二画面数据通过连接的串行接口发送至第二整机模块，第二整机模块发送至第二触控屏来显示第二画面数据。
S212、当第二主控模块确认对采集卡窗口的窗口化操作时，在当前显示画面上窗口化显示采集卡窗口；
窗口化操作和全屏操作互为逆过程，可以理解的是，全屏操作后，当前处于HDMI通道，而窗口化操作后，当前处于主机通道。
窗口化操作也可以是通过点击侧边栏的预设控件输入，或通过语音输入，当进行窗口化操作后，即从HDMI通道切换为主机通道。
S213、第二主控模块确认对采集卡窗口的缩小操作，按照预设尺寸缩小采集卡窗口；
此时的采集卡窗口覆盖显示屏的大部分区域，为了方便用户操作触控屏上显示的其他内容(如开启视频会议软件，开启即时通信软件等)，用户可以点击采集卡窗口程序的缩小按键来缩小窗口，并控制采集卡窗口按照预设尺寸缩小。当然，此时仍然处于主机通道下。
S214、第二主控模块确认对采集卡窗口进行全屏显示时，在当前显示画面上全屏显示采集卡窗口。
同样的，全屏显示可以是点击侧边栏的预设控件，或语音输入等方式，从缩小的采集卡窗口直接变成全屏窗口，同时从主机通道切换为HDMI通道。
例如，如图7所示，当骨科医生在进行视频会议的同时需要对胸骨的X光画面进行触摸回传操作讲解时，医生通过HDMI采集卡连接第一终端与第二终端，使第一终端的画面数据通过HDMI采集卡传输至第二终端的第二主控模块中，第二主控模块将会控制生成一个采集卡窗口，并将传输而来的画面数据所对应的画面显示在采集卡窗口内。此时医生通过点击第二终端屏幕上的视频会议软件发起操作来发起会议，邀请其他医生参与视频会议来讨论X光画面的情况。第二终端响应发起操作后将通过互联网向其他会议终端发送视频会议请求，并将画面数据发送至接通的会议终端，使参与视频会议的会议终端能够看见第二终端上所显示的第一终端的画面。当医生点击第二终端显示画面侧边栏的预设控件(如“主页”控件)，第二终端将全屏显示采集卡窗口，此时处于HDMI通道下，由于将窗口全屏化显示后医生一般是为了针对显示的画面进行具体的讲解，必要时可能需要点击画面中的内容进行选择、放大、批注等触摸操作，此时，第二终端会将这些触摸操作对应的触摸数据发送至第一终端，使得第一终端根据回传的触摸数据进行控制与反馈。
在本申请一个或多个实施例中，在第二终端的第二主控模块获取到第一终端的画面数 据后，以采集卡窗口形式显示该画面数据，第二主控模块确认接收到对显示画面的共享操作后，将当前显示画面的第二画面数据发送至一会议终端进行显示，会议终端与第二主控模块通过互联网连接，当第二主控模块确认对采集卡窗口进行全屏显示时，向第二整机模块发送通道切换信息，并将第二主控模块的画面数据通过第二HDMI端口发送到第二整机模块的第三HDMI端口，第二整机模块接收到通道切换信息后，将信号源通道切换为HDMI通道，从而可以通过HDMI通道显示画面数据，那么在HDMI通道下，第二整机模块获取第一触摸操作数据后，将该第一触摸操作数据回传至第一主控模块，从而执行第一触摸操作数据对应的触摸操作，并更新第一终端的显示画面，实现触摸回传功能，且可以实现将第一终端的画面数据通过互联网进行画面共享的功能。

接下来结合图8示出的数据传输系统介绍本申请实施例提供的数据传输方法。
如图9所示，图9是本申请实施例提供的另一种数据传输方法的流程示意图。本实施例主要强调实现触摸回传的过程，方法包括：
S301、第一终端通过第一Type-C端口将第一画面数据发送至第二主控模块的第二Type-C端口，第一画面数据包括显示在第一终端的显示画面的画面数据；
Type-C是一种通用串行总线的硬件接口规范。TypeC双面可插端口最大的特点是支持USB接口双面插入，同时与它配套使用的USB数据线也必须更细和更轻便。
通过USB数据线将第一终端与第二终端的Type-C端口进行连接，并实现将第一终端所显示的画面数据传输至第二终端的第二主控模块。
S302、第二主控模块通过第二Type-C端口接收到第一画面数据后，通过主机通道在第二终端上显示采集卡窗口，并在采集卡窗口内显示第一画面数据；
由于两个端口相同，因此，可以不用对第一画面数据进行格式转换。第二主控模块通过第二Type-C端口接收到第一画面数据后，可以根据第二主控模块的设置进行相应形式的显示，例如作为窗口进行显示、全屏显示，或者弹出一个窗口，供用户确认是否进行显示等。
在本申请实施例中，可通过采集卡窗口的形式显示第一画面数据。
S303、第二主控模块确认对采集卡窗口进行全屏显示时，向第二整机模块发送通道切换信息，并将第一画面数据通过第二HDMI端口发送到第二整机模块的第三HDMI端口；
S304、第二整机模块接收到通道切换信息后，将信号源通道由主机通道切换为HDMI通道，并接收第二主控模块发送的第一画面数据后，通过第二触控屏显示第一画面数据；
S305、第二整机模块获取第二触控屏的第一触摸操作数据后，并通过触摸线端口将第一触摸操作数据发送至第一主控模块的第一USB端口；这里，第二整机模块获取第二触控屏的第一触摸操作数据后，也可以执行相应的触摸操作，在第二终端也实现对第一触摸操作数据的响应；
S306、第一终端通过第一USB端口接收到第一触摸操作数据后，执行第一触摸操作数据对应的触摸操作，并更新第一终端的显示画面。
其中，S303～S306的具体描述可参见S103～S106，此处不再赘述。
在本申请实施例中，不需要HDMI采集卡，通过带着两个Type-C的数据线将第一终端与第二终端进行连接，实现两个终端的串口连接，以实现两者的数据交互，这种连接方式简单方便，并可以节省成本。另外，在第二终端的第二主控模块获取到第一终端的画面数据后，以采集卡窗口形式显示该画面数据，当第二主控模块确认对采集卡窗口进行全屏显示时，向第二整机模块发送通道切换信息，并将第二主控模块的画面数据通过第二HDMI端口发送到第二整机模块的第三HDMI端口，第二整机模块接收到通道切换信息后，将信号源通道切换为HDMI通道，从而可以通过HDMI通道显示画面数据，那么在HDMI通道下，第二整机模块获取第一触摸操作数据后，将该第一触摸操作数据回传至第一主控模块，从而执行第一触摸操作数据对应的触摸操作，并更新第一终端的显示画面，实现触摸回传功能，且可以实现将第一终端的画面数据通过互联网进行画面共享的功能。
下面结合第二终端对本申请中提及的触摸回传过程进行说明。
需要说明的是，第一终端仅连接局域网，第二终端连接互联网。第二终端包括主机通道和HDMI通道。这两个通道用于接收不同的信号源的输入信号，从而可以在不同的信号源通道之间切换，以呈现不同信号源提供的媒体内容。其中，主机通道所接入的信号源为主机模块，从而主机通道用于呈现交互平板的主机模块所输入的媒体数据。HDMI通道用于呈现通过交互平板的HDMI接口所接入的信号源的媒体数据。
具体的，将第二终端的系统模式切换至复制屏模式，在复制屏模式下可在主机通道以及HDMI通道之间进行切换。在第一终端的显示画面上显示第一画面数据，第一终端将该第一画面数据传输至第二终端，第二终端接收第一画面数据，在主机通道的当前显示画面上显示一采集卡窗口，并在该采集卡窗口内显示第一画面数据。
当用户对该采集卡窗口进行全屏操作时，第二终端确认对采集卡窗口进行全屏显示，将信号源通道由主机通道切换到HDMI通道，并在HDMI通道中全屏显示第一画面数据。
由于此时处于HDMI通道下，第二终端在接收到用户输入的第一触摸操作数据后，执行相应的触摸操作，并将第一触摸操作数据发送至第一终端，使得第一终端接收到第一触摸操作数据后，执行第一触摸操作数据对应的触摸操作，并更新第一终端的显示画面，从而实现在第二终端上的触摸操作回传至第一终端。
在HDMI通道下，第二终端还可以接收用户输入的第二触摸操作数据，并在当前显示界面上显示相应的书写笔迹。当第二终端还连接有会议终端时，同步将第二触摸操作数据发送至会议终端，使得会议终端根据第二触摸操作数据显示相应的书写笔迹，从而保持第二终端与会议终端显示画面相同的效果。从而通过本方法，不仅可以将第二终端上的触摸操作数据回传到第一终端，也可以实现在第二终端上的触摸操作数据发送到会议终端进行显示。
在HDMI通道下，第二终端可以接收会议终端发送的第三触摸操作数据后，
执行第三触摸操作数据对应的触摸操作，并更新HDMI通道的显示画面，以此实现通过会议终端操控第二终端显示界面的效果。
当然，用户可通过操作第二终端而退出HDMI通道，从而将第二终端的信号源通道切换为主机通道。在主机通道下，当确认对采集卡窗口的窗口化操作时，从全屏模式变为窗口化模式，并在当前显示画面上窗口化显示采集卡窗口。而退出HDMI通道的可实现方式包括在当前显示画面上显示整机侧边栏，用户点击整机侧边栏的预设控件，则确认接收到退出HDMI通道的操作指令。
为了方便操作显示界面上的应用软件或工具，用户可调节采集卡窗口的大小，在第二终端确认接收到对采集卡窗口的调整操作，按照预设尺寸调整采集卡窗口。
此外，第二终端与会议终端通过互联网连接。在主机通道下，用户可以操作相应的视频会议软件，当第二终端确认接收到对当前所显示的第二画面数据的共享操作后，将第二画面数据发送至所连接的会议终端进行显示，从而可以实现画面共享的效果。其中，第二画面数据的共享操作可以由第二终端被动接收，即第二终端可以通过视频会议软件接收到会议终端发送的显示画面的共享请求，并接收到用户对共享请求进行确认的操作后，确认接收到对显示画面的共享操作；也可以由第二终端主动发起，即第二终端接收到用户在视频会议软件上发起的对显示画面的共享指令后，确认接收到对显示画面的共享操作。
在一实施例中，第二终端与第一终端通过HDMI采集卡连接，HDMI采集卡用于采集第一终端的第一画面数据，并将第一画面数据发送至所述第二终端，第一画面数据包括显示在第一终端的显示画面的画面数据。在另一实施例中，第二终端与第一终端通过Type-C连接线连接，由第一终端通过Type-C连接线直接将显示在第一终端的显示画面的第一画面数据发送到第二终端。
在本申请一个或多个实施例中，在第二终端获取到第一终端的画面数据后，以采集卡 窗口形式显示该画面数据，第二终端确认接收到对显示画面的共享操作后，将当前显示画面的第二画面数据发送至一通过互联网连接的会议终端进行显示，当第二终端确认对采集卡窗口进行全屏显示时，将信号源通道切换为HDMI通道，从而可以通过HDMI通道显示画面数据，那么在HDMI通道下，第二终端获取第一触摸操作数据后，将该第一触摸操作数据回传至第一终端，从而使得第一终端执行第一触摸操作数据对应的触摸操作，并更新显示画面，实现触摸回传功能，且可以实现将第一终端的画面数据通过互联网进行画面共享的功能。
