| 摘 要： | 针对当前市场上对双路视频监控系统的需求,设计并实现了一种基于FPGA和ARM11的双路远程视频监控系统。该系统通过两个SAA7111A芯片接收解码两路CVBS信号,并在FPGA的控制下将两路信号合成一路传输给ARM11模块。ARM11模块将接收到的视频流打包压缩后发送到IP网上,客户端通过网络连接获取两路监控画面。经过测试表明,该系统性能稳定,能够实现双路视频信号的稳定播放,符合视频产品的设计要求。

| Abstract: | Aiming to the current market demand for two-way video monitoring system,dual remote video monitoring system based on FPGA and ARM11 was designed and implemented.The system can receives two CVBS signals by two SAA7111A decoder chips.Under the control of the FPGA,the two-way signal was synthesized to one way and transmitted to the ARM11 module.ARM11 module can compress a received video stream into packages and send to the IP Internet.The client can obtain two-way monitor screen through the network connection.... |
