Abstract

In this paper, we model the Digital Video Broadcasting-Terrestrial 2 (DVB-T2) system on a typical transmitter station in the content regionalization mode by using multilayer graphs to evaluate its reliability parameters. One of the proposed models characterizes the states of the broadcasting system when using only local content insertion in accordance with ETSI TS 102773. The second model, also implemented as a multilayer graph, describes the states of the system when the regionalization devices are cascaded. Based on the proposed expressions for the probability of 100% uptime operation of each broadcasting system, their parameters are evaluated, showing that the system with cascade content insertion has an availability factor that is 3.28% higher than that of the system with content insertion based on physical layer pipe (PLP) replacement, with the direct reservation of the cascade scheme improving its reliability by 9.77%.

典型发射机台DVB-T2系统的可靠性评估方法

摘要

在本文中，我们通过使用多层图评估其可靠性参数，在内容区域化模式下的典型发射机站上对地面数字电视广播2（DVB-T2）系统进行建模。当仅使用根据ETSI TS 102773的本地内容插入时，提出的模型之一描述了广播系统的状态。第二种模型（也实现为多层图）描述了当区域化设备被级联时的系统状态。根据提议的每个广播系统100％正常运行时间概率的表达式，对它们的参数进行了评估，结果表明具有级联内容插入的系统的可用性系数比具有基于内容广播的系统的可用性系数高3.28％。物理层管道（PLP）更换，
