BROADCAST RECEIVER AND A METHOD FOR CONTROLLING A BOOSTER FUNCTION, PARTICULARLY FOR IMPLEMENTING A VIDEO BOOSTER FUNCTION THROUGH THE CONTROL OF A NOISE REDUCTION FUNCTION IN A VIDEO DECODER

摘要

PURPOSE: A broadcast receiver and a method for controlling a booster function are provided to implement a video booster function through the detection of a noise meter level in a video decoder by deleting an LNA(Low Noise Amplifier) block of a tuner.;CONSTITUTION: An A/D(Analog to Digital) converter(212) converts an RF signal or an analog RGB signal into a digital signal, and a video decoder(211) converts one of a TV signal, a composite signal, an S-video signal and a component signal into a digital video signal. The video decoder detects a noise meter level form the digital video signal. A DNR(Dynamic Noise Remover)(216) drives a booster function for the digital video signal by comparing the noise meter level with the preset noise level.;COPYRIGHT KIPO 2011
