摘　　要：随着SMPTE ST2110系列技术标准的发布,以数字分量串行接口(Serial Digital Interface,SDI)基带信号为主的播出系统逐步向IP架构的数据流系统过渡。在IT技术的支持下,IP架构的播出系统展现了较高的灵活性和性价比,但同时也存在系统复杂和信号监控检查不便的现象。本文通过对曲靖市广播电视台IP化高清电视播出系统建设的介绍,探讨城市电视台新一代智能播出系统的技术发展方向和实际运用。With the release of SMPTE ST2110 series technical standards,the broadcasting system based on the baseband signal of digital component serial interface(SDI)is gradually transitioning to the data flow system of IP architecture.With the support of IT technology,the broadcast system based on IP architecture shows high flexibility and cost performance,but at the same time,it also has the phenomena of complex system and inconvenient signal monitoring and inspection.This paper introduces the construction of IP HD TV broadcasting system of Qujing radio and television station,and discusses the technical development direction and practical application of the new generation intelligent broadcasting system of urban television station.
