Abstract

본 발명은 티브이 수신기의 음성처리장치에 관한 것으로서, 특히 티브이 채널변경 및 시청거리 이동시 갑작스런 음량변도에 대해 일일이 음량이 재조정해야함을 개선하고자 하는 청취력 테스트에 의한 자동음량조정장치와 방법에 관한 것이다.The present invention relates to a sound processing apparatus of a TV receiver, and more particularly, to an apparatus and a method for automatically adjusting the volume by a hearing test to improve the need to readjust the volume for a sudden volume change during TV channel change and viewing distance shift.

수신되는 영상신호와 음성신호는 송신장치 및 중계기 거리에 따라 채널마다 입력세기가 다르다 특히 위성방송은 일반신호에 비해 입력세기가 굉장히 크며, 또한 그때 그때 기후환경 및 시청자의 시청거리에 따라서도 영향을 받게 되므로 채널변경시마다 음량조정의 필요성을 시청자는 느끼게 되므로 종래 티브이 음성처리장치는 시청자가 필요에 따라서 음량을 조정해주어야만 한다.Incoming video and audio signals have different input strengths depending on the distance between the transmitter and the repeater. In particular, satellite broadcasting has a much higher input strength than general signals, and also affects the weather environment and the viewing distance of the viewer at that time. Since the viewer feels the necessity of adjusting the volume every time the channel is changed, the conventional TV voice processing apparatus must adjust the volume as necessary.

본 발명은 이와같은 종래의 문제점을 해결하기 위하여 시청자의 청취력 테스트를 할 수 있도록 하여 마이컴에 시청자의 청취력 등급을 저장하였다가 스피커로 출력되는 음성신호의 레벨을 검출하여 출력되는 음성레벨과 사용자의 청취력 테스트 및 설정거리에 의한 적정 음성신호의 레벨을 비료하여 음량을 자동조정하여 줄수 있도록 하므로서, 티브이의 내부 및 외부 조건등에 의하여 변경되는 최적의 음량을 다시 조정하기 위한 시청자의 불편을 덜어주게 되며, 최적의 조건에서 시청자가 티브이를 시청하도록 할 수 있게 되는 것이다.In order to solve the conventional problems, the present invention enables the viewer's listening ability test to store the listening level of the viewer in the microcomputer, and then detects the level of the audio signal output to the speaker and outputs the user's listening power. It can reduce the inconvenience of viewers to re-adjust the optimum volume changed by the internal and external conditions of the TV by fertilizing the appropriate voice signal level according to the test and setting distance. In this condition, viewers will be able to watch TV.
