Abstract
본 발명은 노래 반주용 비디오 카세트 레코더(KARAOKE VlDEO CASSETTE RECORDER)에 관한 것으로서, 더욱 상세하게는 입력되는 오디오 레벨값이 기준 오디오 레벨값 이상으로 입력될 경우 출력되는 오디오레벨을 일정 레벨이하로 출력하는 노래 반주용 비디오 카세트 레코더의 음량 레벨 제어 방법에 관한 것이다.The present invention relates to a song accompaniment video cassette recorder (KARAOKE VLDEO CASSETTE RECORDER), and more particularly, a song that outputs an audio level output below a predetermined level when an input audio level value is input above a reference audio level value. A volume level control method of an accompaniment video cassette recorder.
이를 위하여 본 발명은, 입력되는 오디오 신호의 출력 레벨을 자동으로 제어하여 출력을 안정화시키는 노래 반주용 브이씨알의 음량 레벨 제어 방법으로서, 입력되는 오디오 신호로부터 DC화된 오디오 레벨값을 검출하는 단계(200)와; 검출되는 DC화된 오디오 레벨값과 기설정된 오디오 레벨값을 비교하여 검출되는 DC화된 오디오 레벨값이 기설정된 오디오 레벨값보다 크면 출력 오디오 레벨을 일정 레벨이하로 출력시키는 단계(210,220)를 포함하므로써, 출력 특성을 안정화하여 스피커 및 제품을 보호하는 효과가 있다.To this end, the present invention is a volume level control method of the song accompaniment V-Cal to automatically control the output level of the input audio signal to stabilize the output, detecting the DC level of the audio level value from the input audio signal (200) )Wow; And outputting the output audio level below a predetermined level when the detected DCized audio level value is greater than the preset audio level value by comparing the detected DCized audio level value with the preset audio level value. Stabilizes the characteristics to protect the speaker and the product.
