| Summary: | In order to make better use of Hi3559′s powerful video image processing capabilities in the field of industrial sites and security monitoring, to achieve long-distance transmission of high-definition video and intelligent algorithms，adopting Hi3559+FPGA hardware architecture, using the coaxial cable transmission method with the high-definition digital interface(HD-SDI) video equalizer, this paper designs and realizes the multi-channel 1080P high-definition video transmission system. This design system solution mainly solves that although Hi3559 supports a variety of Sensor video interfaces, it does not have an input method and design solution that can directly support multiple HD-SDI cameras. The system uses Hi3559 to realize 8-channel HD-SDI video image acquisition, transmission, processing and panoramic display. Compared with HiSilicon′s common camera serial interface(Camera Serial Interface，CSI) interface transmission scheme, HD-SDI transmission distance is farther theoretically up to 200 m. Through testing and verification, the design scheme is feasible, long transmission distance, stable and reliable, and has high promotion and application value for the acquisition and transmission of multi-channel HD-SDI video and panoramic display. |
