NOISE IMPROVING METHOD OF A BROADCASTING RECEIVER CAPABLE OF ADJUSTING AN OUTPUT LEVEL OF A TUNER BY USING IMAGE QUALITY FACTORS

摘要

PURPOSE: A noise improving method of a broadcasting receiver is provided to effectively reduce neighbor channel interference noise without adding hardware.;CONSTITUTION: A broadcasting receiver receives a broadcasting signal(S1010). According to preset tuner output level, the broadcasting receives outputs the broadcasting signal. The broadcasting receiver decodes the outputted broadcasting signal(S1020). The broadcasting receiver calculates an PSNR(Peak Signal to Noise Ratio) of the stored broadcasting signal. The broadcasting receiver adjusts the tuner output level through comparison of a predetermined threshold value and the PSNR value(S1060,S1070).;COPYRIGHT KIPO 2011
