Abstract


With the development of computer technology , microelectronics technology and the Internet , video processing system has been widely used in many areas of daily life , military , industrial and medical . Most of the digital video system video capture through image acquisition card , PC-based digital video system , there are some disadvantages , such as poor stability of the system , install portable inconvenience , high cost , and can not be used in harsh environments and so on. At the same time , due to the rapid development of VLSI and embedded hardware and software technologies , such as TI's DSP, Motorola 's PowerPC powerful embedded processor prices in becoming less and less , especially DSP chip , it is rich peripheral interface and a high degree of programmability makes video surveillance hardware and software are easier to implement , and its application to video surveillance systems also overcome many shortcomings of the PC - based system . DSP-based video processing system , has become the focus of people 's studies as an important way to achieve real-time processing . This paper described the development and implementation of methods for embedded video processing systems and video acquisition system based on a dedicated image processing chip , the analysis of high-speed DSP - based video capture system and PC-based video capture system . Major research and design embedded video surveillance processing system , the master chip using TI's dedicated multimedia processing chip TMS320DM642 . This article was first carried out the design of the video processing system , including a video circuit , an audio circuit , the memory circuit , and a power supply circuit . On this basis , the network transmission of video systems and off-site storage , Ethernet network interface system is designed , the video terminal to capture the video data is transferred via Ethernet to the PC side to achieve remote monitoring function .
