Abstract

본 발명은 방송모드 자동전환방법에 관한 것으로서, 수신된 음성신호의 방송방식에 따라 방송모드가 자동으로 전환되도록 하기 위하여, 방송신호를 튜닝하는 튜너와, 방송신호에 포함되어 있는 스테레오 파일럿신호를 검출하는 디코더, 및 상기 구성부를 제어하는 마이크로 컴퓨터를 구비하는 음성신호 처리장치의 방송모드 자동 전환방법에 있어서; 상기 디코더를 통하여 현재 수신되는 방송신호 중 스테레오 파일럿신호의 포함유무를 검출하고; 상기 튜너에서 출력된 자동이득제어전압값을 검출하여 검출된 자동이득 제어전압값이 설정치보다 큰 값이면, 방송모드를 스테레오모드로 자동전환하여 음성신호를 알채널과 엘채널로 분리하여 신호처리하도록 하였다.The present invention relates to a broadcast mode automatic switching method, in order to automatically switch the broadcast mode according to the broadcast method of the received voice signal, a tuner for tuning the broadcast signal, and detecting a stereo pilot signal included in the broadcast signal A broadcast mode automatic switching method of a voice signal processing apparatus having a decoder and a microcomputer for controlling the configuration unit; Detecting whether a stereo pilot signal is included in broadcast signals currently received through the decoder; If the auto gain control voltage value detected by the tuner is detected and the detected auto gain control voltage value is larger than the set value, the broadcast mode is automatically switched to the stereo mode so that the voice signal is separated into the AL channel and the EL channel for signal processing. It was.

방송신호를 튜닝하는 튜너와, 방송신호에 포함되어 있는 스테레오 파일럿신호를 검출하는 디코더, 및 상기 구성부를 제어하는 마이크로 컴퓨터를 구비하는 음성신호 처리장치의 방송모드 자동전환방법에 있어서; 상기 디코더를 통하여 현재 수신되는 방송신호 중 스테레오 파일럿 신호의 포함유무를 검출하고, 상기 튜너에서 출력된 자동이득제어전압값을 검출하여 검출된 자동이득제어전업값이 초기 설정된 설정치보다 큰 값인가를 체크하며; 스테레오 파일럿신호가 존재하고, 자동이즉제어전압값이 설정치보다 큰 값이면, 방송모드를 스테레오모드로 자동 전환하여 음성신호를 알채널과 엘채널로 분리하여 신호처리하도록 한 것을 특징으로 하는 방송모드 자동전환방법.A broadcast mode automatic switching method of an audio signal processing apparatus comprising a tuner for tuning a broadcast signal, a decoder for detecting a stereo pilot signal included in the broadcast signal, and a microcomputer for controlling the configuration unit; The presence or absence of a stereo pilot signal among the broadcast signals currently received through the decoder is detected, and the auto gain control voltage value output from the tuner is detected to check whether the detected auto gain control voltage value is greater than the initially set value. To; If the stereo pilot signal is present and is automatic, that is, the control voltage value is higher than the set value, the broadcast mode is automatically switched to the stereo mode so that the audio signal is separated into the R channel and the L channel to process the signal. Automatic switching method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
