摘　　要：数字电视网络,既是数字电视技术发展的产物,也是支撑数字电视技术进一步发展的基础。在当前积极推进数字电视网络IP化、光纤化改造的背景下,如何降低数字电视网络故障发生率,确保网络的安全性、稳定性,以适应数字电视安全可靠、高速智能的网络需求,逐渐成为数字电视网络技术研究与应用中的重点内容。基于此,在概括介绍数字电视网络的基础上,就其运行中常见的故障以及故障防范与维护策略进行探讨分析,为数字电视网络建设中的故障防范与维修提供相关内容参考。Digital TV network is not only the product of the development of digital TV technology, but also the foundation to support the further development of digital TV technology. At present, under the background of actively promoting the IP-based and fiber-based transformation of digital TV network, how to reduce the failure rate of digital TV network and ensure the security and stability of the network, so as to meet the network demand of digital TV for security, reliability, high speed and intelligence, has gradually become the key content in the research and application of digital TV network technology. Based on the general introduction of digital TV network,this paper discusses and analyzes the common faults in its operation, as well as the strategies of fault prevention and maintenance, so as to provide relevant reference for the fault prevention and maintenance in the construction of digital TV network.
