A kind of solution based on TI OMAP4460 multimedia platform is put forward, making full use of the V4L2 video collection framework,combined with H. 264 compression coding technology and adopted RTSP streaming technology to realize the remote video monitoring system. Through the construction of the software platform and hardware platform, the analysis of the original video data acqui- sition process and the realization of real -time video remote transmission, comprehensively show the implementation of the network video monitoring system. The experiment has verified the feasibility of the embedded remote monitoring and control system. Results show that the system can collect the live video information timely and accurately, besides, the collected data can be transmitted through the Ethernet to client successfully. The real-time and stability of the system meets the needs of real-time data transmission and remote monitoring.
