　　点击界面左下角的“高级设置”按钮，在弹出的“高级设置”界面中，在“视频参数”区域中，取消勾选“服务器配置参数“，在分辩率下拉菜单中选择分辩率1280x720或（1920x1080），将帧率设置为25，将码率设置为1000kbps，然后点击”应用更改“按钮，关闭”高级设置“界面，再打开，可以看到”当前分辨率“提示信息，如下图所示：

　　三、Remote Viewing:
　　三、远程观看：
　　Running the same program on the other computers, sign-on system, intothe same room, double-click any user name in the user list, you can see thevideo of the user, double-click to zoom display, double-click again to fullscreen display.
　　在其它计算机再运行同样的程序，登录系统，进入同样的房间，在用户列表中双击任意用户名，即可看到该用户的视频，双击可放大显示，再次双击可全屏显示。
　　Remark:
　　1、HD video requiresthe support of the camera.Currently available in the market most of the camera does not support HDvideo,HD resolution (as set in the”Advanced Settings” interface: 1920x1080) doesnot necessarily support.When the camera doesn’t support theresolution,AnyChat SDK will automatically match the most appropriateresolution.
　　2、We tested supportfor high-definition resolution camera: Logitech C920、C910，LifeCam HD-5000、HD-6000 and so on；
　　3、Full HD (1920x1080)suitable for LAN,or fiber-opticnetwork to use,slightly higher CPU and bandwidthrequirements,HD (1280x720) is more suitable for Internet applications.

　　备注：
　　1、高清视频需要摄像头的支持，目前市面上的大部分摄像头不支持高清视频，所以在”高级设置“界面设置的高清分辩率（如：1920x1080）并不一定被支持，当摄像头不支持该分辩率时，AnyChat SDK会自动匹配一个最合适的分辨率；
　　2、目前我们测试支持高清分辩率的摄像头有：Logitech C920、C910，LifeCam HD-5000、HD-6000等；
　　3、全高清（1920x1080）适合局域网，或是光纤网络使用，对CPU和带宽要求稍高，而高清（1280x720）较适合互联网应用；
