Abstract

본 발명은 일정한 신호를 송신하는 신호송신수단을 별도로 사용자에게 부착시키고서 사용자에 의한 음량자동조절모드시 그 신호송신수단으로부터 신호를 수신하게 됨에 따른 수신감도를 기초로 하여 현재의 음량레벨을 자동으로 조절함으로써 사용상의 편리함을 도모하고자 한 텔레비전의 음량레벨 자동조정장치 및 그 방법을 제공하기 위한 것이다.According to the present invention, a signal transmission means for transmitting a predetermined signal is separately attached to a user, and automatically receives a current volume level based on a reception sensitivity according to a signal received from the signal transmission means in the automatic volume control mode. SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic volume level adjusting apparatus for a television, and a method thereof, which aims at convenience of use by adjusting.

이를 위해 본 발명은, 방송채널의 선국을 위한 튜너(14)와, 상기 튜너(14)에 의해 선국된 방송신호의 음성신호를 처리하는 음성처리수단(16,18,20) 및, 상기 방송신호의 영상신호를 처리하는 영상처리수단(22,24,26)을 포함하여 구성된 텔레비전에서, 음량자동조절모드의 설정/해제가 가능한 제어기능설정부(10)와, 해당 텔레비전에 대하여 일정한 신호를 무선전송하는 신호송신수단(28), 상기 신호송신수단(28)으로부터의 신호를 수신하는 수신부(30), 상기 수신된 신호의 레벨과 기설정된 기준신호의 레벨을 상호비교하고 그 비교결과에 따른 차이치를 음량조절치로서 출력하는 음량조절치추출부(32) 및, 상기 음량자동조절모드가 설정되면 상기 음량조절치추출부(32)로 부터의 신호를 기초로 자동적인 음량조절동작이 행해지도록 음량조절부(34)를 제어하는 제어부(12)를 추가로 구비하고서, 입력되는 제어기능이 음량자동조절모드용 제어기능인지를 판단하고 그 음량자동조절모드용 제어신호인 경우에는 외부의 신호송신수단(28)으로부터 송신되는 신호를 수신하여 기준신호와 상호비교하고 나서 상기 비교결과에 따른 차이치를 기초로 현재의 음량레벨에 대한 자동적인 조절동작을 행하는 것이다.To this end, the present invention provides a tuner 14 for tuning a broadcast channel, voice processing means 16, 18, and 20 for processing a voice signal of a broadcast signal tuned by the tuner 14, and the broadcast signal. In a television comprising image processing means (22, 24, 26) for processing a video signal of a control function, the control function setting section (10) capable of setting / cancelling the automatic volume control mode and a predetermined signal for the television The signal transmitting means 28 for transmitting, the receiving unit 30 for receiving the signal from the signal transmitting means 28, the level of the received signal and the level of the predetermined reference signal are compared with each other and the difference according to the comparison result. The volume control value extracting unit 32 for outputting the value as the volume control value, and the volume control operation is performed based on the signal from the volume control value extracting unit 32 when the volume automatic control mode is set. Control to control the adjuster 34 (12) is further provided, judging whether the input control function is a control function for the automatic volume control mode, and receiving the signal transmitted from an external signal transmission means (28) when the control signal for the automatic volume control mode is used. After comparing with the reference signal, the automatic adjustment operation for the current volume level is performed based on the difference value according to the comparison result.
