有线电视全频带信号监测

CATV Full-Band Signal Monitoring

随着有线电视系统的发展及高清、超高清电视节目的播出,对电视信号传输质量的要求越来越高,实施有线电视信号质量监测,保证有线电视传输系统的性能十分必要。全频带信号采样技术的发展为电视信号监测技术的创新奠定了基础,本文针对这个课题,研究了传统电视信号监测系统构成和实现方式,提出了有线电视全频带采样信号监测的方法和机制,利用该方法,不仅提高运营商远程实时监测网络能力,还为运营商提供了一种数据采集和分析的工具。

With the development of CATV system, HDTV and UHDTV broadcasting requires more and more high-qulity signal transmis- sion. The implementation of CATV signal monitoring is necessary to ensure the performance of the CATV transmission system. And the development of full-band signal sampling technology provides the possibility and lays a basis on the innovation of CATV signal monito- ring technology. So this paper researched the traditional signal monitoring system framework and implements, and proposed a signal sampling and monitoring mechanism for the full-band CATV. The mechanism will improve operators＇ remote and real-time monitoring network capacity and will provide a new data gathering and analysis tool.
