嵌入式多源高清视频监控系统设计与实现
Design and implementation of embedded multi-source HD video monitoring system
摘要
Abstract
For the actual application of HD video monitoring system,a set multi⁃source HD video monitoring system based on FPGA and DSP embedded technologies was designed and realized,in which the FPGA and DSP chips are taken as the core of the board,and the modular design thought is adopted to realize the uncompress and image processing functions of the four⁃channel compressed video stream. The SOPC is used to construct the microcontroller system based on Nios Ⅱ soft⁃core proces⁃sor to realize the format conversion,scaling and superposition functions of the video data,and superpose and splice the four⁃channel videos into one⁃channel video. The synchronization of video stream and auxiliary information is implemented by means of hardware programming. The integrated video data is transmitted to the upper computer application program through PCI inter⁃face for display. The system monitoring result is given by the tests. The feasibility and superiority of the system were proved.关键词
