在三大信道解调(卫星解调、数字有线解调和地面解调)标准中,地面解调涉及的通信信道尤为复杂,因而评价解调器的性能指标格外繁杂。对于机顶盒和一体电视机等整机生产商而言,如何提高整机信道接收性能的测试效率,就成为数字电视行业面临的一个难题。以欧洲DVB?T2标准为例,介绍一则自动测量性能指标的方法。

In the three channel demodulation standards(satellite demodulation,digital cable demodulation and ground de?modulation),the communication channel involving in the ground demodulation is particularly complex,and the performance in?dex to evaluate demodulators is complicated too. For the manufacturers of set?top box,whole TV set and other assemblies,the improvement of the test efficiency of TV receiver performance has become a problem. In this paper,taking the European DVB?T2 standard as an example,an automatic testing method of performance index for digital TV is introduced.
