Abstract

본 발명은 텔레비전에서 스피커를 통해 출력되는 오디오신호의 원하는 음장 효과가 발생되도록 하기 위해서는 시청자가 수동으로 적절한 음질을 일일이 조절해야만 하는 불편함을 해결하기 위해 이루어진 것으로, 각각 다른 주파수밴드별 등화레벨이 기억되고서 시청자의 원하는 등화레벨의 선택에 의해 오디오신호가 선택된 등화 레벨대로 음질조정될 수 있도록 하는 텔레비전의 등화레벨 제어장치를 제공한다.The present invention has been made to solve the inconvenience that the viewer must manually adjust the appropriate sound quality in order to produce the desired sound field effect of the audio signal output through the speaker in the television, each equalization level for each frequency band is stored The present invention provides an equalization level control apparatus for television that allows audio signals to be adjusted to the selected equalization level by selection of a desired equalization level of the viewer.

그에 따라 본 발명은, 소정채널의 텔레비전방송신호의 영상신호가 CRT(70)를 통해 영상출력되도록 함과 더불어 오디오신호가 스피커를 통해 음성출력되도록 하는 텔레비전세트에 있어서; 원하는 등화레벨을 키입력을 통해 설정하기 위한 키설정부(10)와, 각각 다른 주파수밴드의 등화도를 갖는 다수의 등화레벨제어데이터가 기여된 메모리부(20), 상기 키설정부(10)로부터의 키설정신호를 입력받아 인식하고서 상기 메모리부(20)에 기억된 해당 등화레벨에 따른 등화레벨제어데이터를 독출하여 오디오신호의 등화레벨이 조절되도록 하는 등화레벨컨트롤신호를 출력함과 더불어 조절된 등화레벨이 표시되도록 제어하는 마이컴(30), 상기 등화레벨컨트롤신호를 입력받아 상기 설정된 해당 등화레벨대로 오디오신호가 등화레벨 조절되도록 하는 등화레벨조절부(40), 상기 마이컴(30)의 제어에 의해 상기 키설정부(10)에서 설정된 해당 등화레벨을 나타내는 OSD문자가 영상증폭부(60)를 매개로 CRT(70)상에 OSD표시될 수 있도록 구동되는 OSD구동부(50)를 더 구비하여 구성된 것을 특징으로 한다.Accordingly, the present invention provides a television set for outputting a video signal of a television broadcast signal of a predetermined channel through a CRT (70) and an audio signal through a speaker; A key setting unit 10 for setting a desired equalization level through key input, a memory unit 20 to which a plurality of equalization level control data having equalization degrees of different frequency bands are contributed, and the key setting unit 10 Receives and recognizes the key setting signal from the controller and reads out equalization level control data corresponding to the equalization level stored in the memory unit 20 to output an equalization level control signal for adjusting the equalization level of the audio signal. The microcomputer 30 for controlling the display of the equalized level, the equalization level control signal is input, the equalization level control unit 40 for controlling the equalization level of the audio signal according to the set equalization level, and the control of the microcomputer 30. The OSD driver 50 is driven so that the OSD character indicating the equalization level set by the key setting unit 10 can be displayed on the CRT 70 via the image amplifier 60. Provided to is characterized in that configured.
