摘要
为了使大流量数据的远程无线传送更加方便,本系统基于第三方公司的网络通信协议栈开发了实时视频传输系统。系统具有两个通信通道,控制信息通过TCP信令通道进行传输。多媒体信息通过UDP媒体通道进行传输。车载设备通过每隔一定的时间向中心平台发送心跳报文,来保证链路的连接。最终实现对车辆进行注册,登录。并可以在远端实时查看车内情况的视频与音频。
Large flow of data in order to make long-range wireless transmission easier, this system is based on a third party＇s network protocol stack development of real-time video transmission systems. System has two commu- nication channels, the control signaling information is transmitted through TCP channel. Multimedia information transmission media channel via UDP. Vehicle device sends a heartbeat packet to the central platform through reg- ular intervals to ensure that the connection link. And ultimately the vehicle registration, login. And you can view real-time video and audio situation inside at the far end.
