Since AnyChat Platform Core SDK V4.5version, AnyChat support real-time HD video 720P (1280x720) and Full HD video1080P (1920x1080) video, to achieve a one-to-one HD real-time call can alsoachieve many to many high-definition real-time meeting, the following describeshow AnyChat SDK Demo program to demonstrate the effect of high-definitionvideo.
自AnyChat PlatformCore SDK V4.5版本开始，AnyChat便支持高清视频720P（1280x720）和全高清视频1080P（1920x1080）的实时视频，可实现一对一的高清实时通话，还可以实现多对多的高清实时会议，下面讲述如何用AnyChat SDK中的Demo程序快速的演示高清视频效果。
一、Download the SDK
一、下载SDK包
Click to open the download page, unzip, andthen enter the SDK package: bin \ demo \ directory, run inside:BRAnyChatMeeting.exe program, log on to the system with any account, enter anyroom, as shown in the following figure:
点击打开下载页面，解压缩，然后进入SDK包的：bin\demo\目录，运行里面的：BRAnyChatMeeting.exe程序，用任意帐号登录系统，进入任意一个房间，如下图所示：
二、set the parameters
二、设置参数
Click interface “Advanced Settings” buttonon the lower left corner,In the “Advanced Settings” pop-up interface,the area of videoparameters,uncheck the server configuration parameters,Resolution1280x720 or select in the drop-down menu in the resolution (1920x1080), theframe rate is set to 25,set the bit rate to 1000kbps,thenclick on the “Apply Changes”button.Close the“Advanced Settings”interface,then open again,you can see the current resolution tips,asshown in the following figure:
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；
