本申请实施例提供的视频会议的控制系统采用以下技术方案，提出一种新的音视频通讯中的双流辅视频画面控制方法，核心是在通讯的过程中终端设备接收用户控制指令对双流辅视频画面进行控制。
具体方案如下：
在视频会议系统的终端设备上，安装辅视频控制接收和处理装置(该装置可以为软件、或者独立硬件方式存在)，该装置在收到用户控制申请指令(控制指令的发送设备可以是配套的遥控器或手机、平板等移动设备)时，对指令进行识别和处理；
1、对当前会场生效，则直接冻结本会场的辅视频画面，并等待接收画面内容选中指令，装置收到指令后将画面选中内容进行高亮显示，用户还可通过装置下发画面缩放、移动等处理指令，对辅视频画面选中内容进行移动、缩放等处理结果输出展示到本端会场
2、对所有会场生效，需取得辅视频令牌所在会场的允许，若允许则冻结所有会场的辅视频画面，这时所有的会场都能看到上述1操作产生的辅视频画面，否则仅本端会场看到处理后的辅视频画面。
下面结合附图及实施例对本申请实施例中的技术方案进行详细的阐述。
图7是本申请实施例提供的视频会议的控制系统中两方音视频通讯的组网图，其中S为辅视频画面控制装置。

控制指令发送模块(遥控器或手机、平板移动设备)可通过红外、网络、蓝牙等 无线通讯技术向辅视频画面控制装置S发送辅视频画面的选择高亮和缩放指令
辅视频画面控制装置S的控制指令接收模块收到指令后对指令进行编译处理，辅视频图像处理模块根据指令将画面选中区域、要高亮显示的颜色、缩放倍数等信息进行图像编解码处理生成新的辅视频画面
图10是本申请实施例提供的视频会议的控制系统中辅视频画面控制的流程示意图，其中，具体流程如下：
1.会场安装了辅视频画面控制装置；
2.视频会议系统开始会议，终端A会场发送了双流辅视频；
3.终端B会场申请控制双流辅视频画面；
4.根据系统权限允许终端B控制类型是对所有会场辅视频控制还是仅对本会场的辅视频进行控制；
5.如果终端B有控制所有会场辅视频画面权限则冻结所有会场辅视频画面，否则仅冻结本会场的辅视频画面；
6.用户通过辅视频控制装置的控制指令发送模块发送辅视频画面操作指令(对画面内容的选中、高亮、缩放)；
7.控制指令接收模块收到指令后，由辅视频控制装置中的辅视频图像处理模块进行处理合成生成新的辅视频画面；
8.将新生成的辅视频画面输出到终端显示设备上。
本申请实施例提出一种新的音视频通讯中的控制双流的方法，核心是在通讯的过程中分会场可对双流辅视频画面进行控制，具有以下优点：
a、可根据需要对画面内容进行选中高亮，缩放，方便用户对画面的细节进行查看分析
b、各个分会场可申请权限进行操作，而不是不仅仅是双流发送的会场进行控制
