摘要
针对地面数字电视700 MHz频率迁移项目实施中普遍存在的单频网组网效果不佳等问题,在详细分析单频网系统组成和传输网络结构的基础上,提出一种新的单频网网络优化方案,并结合单频网同步测试进行了网络运行效果验证。测试结果表明所提方案具有可行性和有效性,可为地面数字电视单频网的稳定运行提供指导性建议。
Aiming at the poor networking effect of single-frequency network in the implementation of 700 MHz frequency migration project of terrestrial digital television,a new single-frequency network optimization scheme is proposed on the basis of detailed analysis of the system composition and transmission network structure of single-frequency network,and the network operation effect is verified by combining the synchronous test of single-frequency network.The test results show that the proposed scheme is feasible and effective,which provides guiding suggestions for the stable operation of terrestrial digital television single frequency network.
