本文在介绍插测技术和插测信号的基础上,说明电视信号进行动态测量的必要性和优越性。并介绍电视信号的主要失真参数定义和测量方法。最后指出,随着测量技术的进一步发展,动态测量的精度将进一步提高,将在电视传输网络的自动监测和发射台的无人值守方面获得广泛的应用。 Based on the introduction of plug-in technology and plug-in test signal, this paper illustrates the necessity and superiority of dynamic measurement of television signal. And introduces the definition and measurement method of the main distortion parameters of the television signal. Finally, it is pointed out that with the further development of measurement technology, the accuracy of dynamic measurement will be further improved, and will be widely used in the automatic monitoring of television transmission network and the unattended launch pad.
