摘要
文中提出了一种基于TI的OMAP4460多媒体平台,利用V4L2视频采集框架,结合H.264压缩编码技术,采用RTSP流媒体技术实现远程视频监控系统的解决方案。通过软硬件平台的搭建,对视频原始数据采集过程的分析和实时视频网络传输的实现,文中较全面地展示了远程视频监控系统的实现过程。通过实际运行验证了该嵌入式远程监控系统的可行性。系统测试结果表明,该系统能够及时准确地采集现场视频图像信息,并通过以太网将采集到的数据远程实时传输,在客户端实时显示,具有实时、稳定的特点,满足了实时数据传输和远程监测的需求。
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.
