Abstract

본 발명은 노래반주 기능을 갖는 VCR에서 노래를 부른 결과를 채점할 수 있는 비디오 카세트 레코더의 채점장치에 관한 것으로, 오디오 처리회로에서 출력되는 채점을 위한 오디오신호만을 필터링하는 로우패스필터; 마이크를 통해 인가되는 음성신호와 로우패스필터를 통해 출력되는 오디오신호를 선택적으로 출력하는 선택회로; 선택회로에서 출력되는 신호를 디지탈신호로 변환하는 변환부; 변환부에서 출력되는 음성신호의 에너지와 이미 저장되어 있던 오디오신호의 기준되는 에너지를 비교하고, 이 비교결과에 의해 얻어진 채점 결과값을 출력하도록 제어하는 시스템제어부; 계산처리된 결과값을 저장하기 위한 메모리; 채점결과값을 디스플레이하기 위한 디스플레이수단; 오디오 처리회로에서 출력되는 채점을 위한 오디오신호와 노래반주용 신호중 노래반주를 위한 오디오 신호만을 필터링하는 하이패스 필터를 포함하도록 구성된다.The present invention relates to a scoring apparatus of a video cassette recorder capable of scoring a result of singing a song in a VCR having a song accompaniment function, comprising: a low pass filter for filtering only an audio signal for scoring output from an audio processing circuit; A selection circuit for selectively outputting an audio signal applied through a microphone and an audio signal output through a low pass filter; A converter for converting a signal output from the selection circuit into a digital signal; A system controller which compares the energy of the audio signal output from the converting unit with the reference energy of the audio signal already stored and outputs a scoring result value obtained by the comparison result; A memory for storing the calculated result value; Display means for displaying a scoring result value; And a high pass filter for filtering only the audio signal for song accompaniment among the audio signal for scoring and the song accompaniment signal output from the audio processing circuit.
