The design and implementation of a networked real-time video surveillance system based on FPGA

Abstract

Video surveillance systems are widely needed nowadays. Typically the system can be realized in platforms such as DSPs, FPGAs, ASICs, or the combination of them. In this paper, we have developed a framework of a networked realtime video surveillance system, and implemented it using two ML402 FPGA development boards provided by Xilinx and a custom video interface daughter board. The designed system utilized Ethernet as its connection between encoding side and decoding side, thus could be easily expanded to multipoint-to- point or multipoint-to-multipoint Ethernet services that would be required by different applications. The codec was based on Xilinx MPEG-4 Part 2 simple profile encoder and decoder IP cores with appropriate configuration in the designed system, which effectively reduced the development time and ensured the real-time encoding and decoding procedure. Furthermore, the system can also be viewed as a system-level video algorithm verification platform.
