Digital broadcast receiver and its reception level decision manner, reception level decision program

摘要

PPROBLEM TO BE SOLVED: To provide a digital broadcast receiver capable of correctly determining a reception state of digital broadcast without being affected by the ambient environment. PSOLUTION: The digital broadcast receiver includes: a digital broadcast reception/demodulation section for receiving/demodulating a digital broadcast wave and outputting a carrier power-to-noise power ratio signal, a data error rate signal and a synchronous state signal; and a reception level determination section for determining a reception level of the received digital broadcast wave signal based on the carrier power-to-noise power ratio signal, the data error rate signal and the synchronous state signal. The reception level can be rightly determined even under environments of a temporal change in reception signal strength, interference wave and frequency selective fading. PCOPYRIGHT: (C)2010,JPO&INPIT
