Abstract
본 발명은 브이 씨 알(VCR)의 RF출력채널의 간섭노이즈 제거장치 및 방법에 관한 것으로 사용자가 비디오 테이프등을 재생시키는 RF출력모드를 설정시켰는지를 판단하고, RF출력모드시에는 안테나를 통하여 핸재 수신되는 주파수의 동기신호를 판단하는 단계; 상기 단계후에 RF출력채널과 현재 수신되는 주파수 출력채널이 동일한지를 판단하는 단계; 상기 단계에서 RF출력채널과 현재 수신되는 주파수의 출력채널이 동일한 채널이 아니라면 사용자가 설정시킨 채널로 RF출력신호를 전송하고, RF출력채널과 현재 수신되는 주파수의 출력채널이 동일한 채널이라면 수신되지 않는 채널을 찾아 그 채널로 RF신호를 출력시키는 단계; 상기 단계에서 수신되지 않는 채널로 RF출력신호가 출력되면 변경된 RF 채널을 표시하고(S5), 변경된 채널로 RF출력신호를 변조하여 전송하는 단계로 이루어져, 통상적인 브이 씨 알의 RF출력채널로 일반방송이나 케이블 TV의 방송이 출력되는 경우에 발생하는 간섭노이즈를 방지하는 것이다.The present invention relates to an apparatus and a method for removing interference noise of an RF output channel of a VCR, and determines whether the user has set an RF output mode for playing a video tape or the like. Determining a synchronization signal of a received frequency; Determining whether the RF output channel and the currently received frequency output channel are the same after the step; In this step, if the RF output channel and the output channel of the currently received frequency are not the same channel, the RF output signal is transmitted to the channel set by the user, and if the RF output channel and the output channel of the currently received frequency are the same channel, they are not received. Finding a channel and outputting an RF signal to the channel; When the RF output signal is output to the channel that is not received in the step (S5), the modified RF channel is displayed, and modulating and transmitting the RF output signal to the changed channel, the general V RF RF output channel is general This is to prevent interference noise that occurs when a broadcast or a cable TV broadcast is output.
