Claims (1)

오디오 처리부로 부터 출력된 오디오 신호를 증폭하여 스피커(2)를 구동시키는 증폭기(1)와 RGB 색신호 및 블랭킹 신호를 출력하는 온스크린 IC(9)와 온스크린 동작을 제어하는 제어신호를 출력하는 마이컴(10)이 구비 된 TV수상기에 있어서, 전자스위치(11)는 온스크린IC(9)의 RGB 색신호를 혼합기(6, 7, 8)와 전자스위치(12)에 선택출력토록 하고 전자스위치(12)는 상기 전자스위치의 출력과 혼합기(6)의 출력을 선택출력토록 하며 전자스위치(13)는 상기 전자스위치(12)의 출력과 영상신호를 선택 출력토록 하되, 오디오 레벨 표시기능이 선택되면 마이컴(10)의 제어에 의해 전자스위치(11)는 온스크린IC(9)의 RGB출력을 혼합기(6, 7, 8)에 선택 출력하여 필터링부(14)에서 필터링된 저중고역 오디오 성분과 혼합되도록 하고, 전자스위치(12)는 상기 혼합기(6,7,8)에서 RGB 색신호와 혼합된 저중고역 오디오 성분을 선택출력토록 하고, 전자스위치(13)는 온스크린IC(9)의 블랭킹신호(BLK)에 의해 제어되어 저중고역 오디오 성분이 혼합된 RGB 색신호를 선택 출력하여 오디오 신호의 크기는 온스크린의 휘도변화로 표시하고 주파수는 색깔구분으로 표시하도록 한것을 특징으로 하는 오디오 레벨 표시장치.An amplifier 1 driving the speaker 2 by amplifying the audio signal output from the audio processor, an on-screen IC 9 for outputting RGB color signals and blanking signals, and a microcomputer for outputting control signals for controlling on-screen operation. In the TV receiver provided with (10), the electronic switch 11 causes the RGB color signals of the on-screen IC 9 to be selectively output to the mixers 6, 7, 8 and the electronic switch 12, and the electronic switch 12 ) Selects and outputs the output of the electronic switch and the output of the mixer 6, and the electronic switch 13 selects and outputs the output and the image signal of the electronic switch 12. Under the control of 10, the electronic switch 11 selectively outputs the RGB output of the on-screen IC 9 to the mixers 6, 7, 8 so as to be mixed with the low and high frequency audio components filtered by the filtering unit 14. In addition, the electronic switch 12 is RGB color in the mixer (6, 7, 8) And the low and high frequency audio components mixed with the selective output, and the electronic switch 13 is controlled by the blanking signal BLK of the on-screen IC 9 to select and output the RGB color signal mixed with the low and high frequency audio components to output the audio signal. The audio level display device characterized in that the size is displayed as the change in the brightness of the on-screen display and the frequency is displayed in color classification. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
