摘要
针对视频监控终端设备中的视频实时显示、编码数据本地存储备份等双重需求,设计了一种基于DM365视频处理芯片、H.264压缩技术、嵌入式Linux操作系统的双码流视频监控终端设备。给出了系统的总体软硬件结构,重点阐述了视频处理子系统模块(包括视频前端采集模块和视频后端显示模块)以及视频编码模块。测试结果表明,系统实时监测性能良好,本地存储的编码数据清晰稳定,具有很强的实用性和广阔的发展前景。
This paper introduces the design of a multiple streaming video monitoring device based on the video processing chip DM365, H.264 encoding technology and embedded Linux. It elaborated on the overall structure of the system hardware and software modules,especially on the video processing subsystem module （including video processing front end and video processing back end） and video encoding module. The client has real-time monitoring of the scene after receiving, and the device has real-time displaying of the captured video and backup the encoded video data. Experimental results show that the system is stable and reliable,and has a wide range of application.
