Design Of Network Video Surveillance SoC And Its Application

Network video surveillance as the mainstream of modern video surveillance has entered various fields.Because network video surveillance SoC is its hardware base,video network transmission is its application base,it is significant to design the network video surveillance SoC and develop its application.In this paper,three key technologies of CIS interface control,SoC monolithic integration and video network transmission are proposed in view of the digitalization,system integration and monitoring network in modern video surveillance.Then introduce the progress and the principles of three key technologies.Then introduce the CIS interface control circuit,network video surveillance SoC,video network transmission specific design and verification.Finally,build the prototype application systemin the FPGA.The main work of this paper is reflected in the following aspects:(1)Designthe SCCB timing,SCCB timing control,video acquisition,video cache,burst transmission,DMA module toachieve CIS configuration,acquire videoin real time,cache video,transfer video in burst mode,move data to other IP core quickly.(2)Design register and APB bus interface for the CIS control IP core and DMA control IP core.Allocate SoC hardware resources.Mount CIS control IP core,DMA control IP core,SPI IP core,cut the SoC to form my own design SoC.(3)Design the server and client of video network transmission based onthe C/S architecture,advantages of TCP and UDP,multi-threaded and socket programming,to establish the foundation of application.In addition,design the application prototype hardware circuit and driverbased on the SoC,CIS,SD card,wifi chip in FPGA,and explore the intelligent video analysis.
