| 摘 要： | 设计了一种视频加密传输设备,利用HDMI或USB接口接收外部摄像机或DV机视频数据流,对视频流数据进行编码,再经过加密处理后,通过4G移动网络将加密压缩的视频流数据传送至服务端。当服务器远端有设备连接时,能接收并播放视频数据。该传输设备软件实现了视频采集编码、4G移动网络、数据加密、TCP/IP协议传输数据等模块,与远端服务器通过私有协议发送加密数据,验证了各模块的工作性能以及可靠性。

| Abstract: | A device that uses HDMI or USB interface to receive video data stream of external camera or DV machine is designed.The device encodesand encrypts the video stream data,then transmits the encrypted and compressed video stream data to the server through 4G mobile network.When a user device is connected to the remote server,it can receiveand play the video stream data.The software of the transmission equipment realizes the modules of video acquisition and coding,4G mobile network,data encryption,TCP/IP protocol for data transmission and so on.It can send encrypted data with remote server through private protocol,which verifies the working performance and reliability of each module. |
