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版本開始，AnyChat便支持高清視頻720P（1280x720）和全高清視頻1080P（1920x1080）的實時視頻，可實現一對一的高清實時通話，還可以實現多對多的高清實時會議，下面講述如何用AnyChat SDK中的Demo程序快速的演示高清視頻效果。
一、Download the SDK
一、下載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:
點擊打開下載頁面，解壓縮，然後進入SDK包的：bin\demo\目錄，運行裏面的：BRAnyChatMeeting.exe程序，用任意帳號登錄系統，進入任意一個房間，如下圖所示：
二、set the parameters
二、設置參數
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:
點擊界面左下角的“高級設置”按鈕，在彈出的“高級設置”界面中，在“視頻參數”區域中，取消勾選“服務器配置參數“，在分辯率下拉菜單中選擇分辯率1280x720或（1920x1080），將幀率設置爲25，將碼率設置爲1000kbps，然後點擊”應用更改“按鈕，關閉”高級設置“界面，再打開，可以看到”當前分辨率“提示信息，如下圖所示：
三、Remote Viewing:
三、遠程觀看：
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.
在其它計算機再運行同樣的程序，登錄系統，進入同樣的房間，在用戶列表中雙擊任意用戶名，即可看到該用戶的視頻，雙擊可放大顯示，再次雙擊可全屏顯示。
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.

備註：
1、高清視頻需要攝像頭的支持，目前市面上的大部分攝像頭不支持高清視頻，所以在”高級設置“界面設置的高清分辯率（如：1920x1080）並不一定被支持，當攝像頭不支持該分辯率時，AnyChat SDK會自動匹配一個最合適的分辨率；
2、目前我們測試支持高清分辯率的攝像頭有：Logitech C920、C910，LifeCam HD-5000、HD-6000等；
3、全高清（1920x1080）適合局域網，或是光纖網絡使用，對CPU和帶寬要求稍高，而高清（1280x720）較適合互聯網應用；
