摘　　要：简要介绍了PSI信息,在此基础上阐述了基于FPGA的PSI信息检测方案,依据DVB ETSI TR 101 290测量标准,对PSI相关参数进行检测。通过对实际码流进行测试,可以实现对PSI进行实时高效的监测。In this paper, the PSI information is briefly introduced, and an achievement scheme of detecting PSI on FPGA is put up. According to DVB ETSI TR 101 290 measurement guideline, some parameters of the PSI are detected. Real-time transport stream, output from the satellite broadcasting receiver, is adopted to check the design. The result of the design on FPGA works real-timely and effectively.
