摘要
阐述了卫星广播电视监测的主要任务,研究了卫星广播电视监测方法,即卫星广播电视监测一般从三个方面进行监测,分别为传输信道、码流和节目。探讨了卫星广播电视监测的主要项目:频谱、调制误差(星座图)、误码率、码流分析、载波电平、信道功率、同步信号、信噪比、音视频节目等,希望能对广播监测技术的实践发展起促进作用。
This paper expounds the main tasks of satellite radio and television monitoring,and studies the monitoring methods of satellite radio and television,that is,satellite radio and television monitoring generally carries out monitoring from three aspects,namely,transmission channel,bit stream and program.This paper discusses the main items of satellite radio and television monitoring:spectrum,modulation error(constellation),bit error rate,bit stream analysis,carrier level,channel power,synchronous signal,signal-to-noise ratio,audio and video programs,etc.It is hoped that this will promote the practical development of broadcasting monitoring technology.
