Abstract

본 발명은 스트레오 음악방송의 기능을 텔레비전수상기에 관한 것으로서, 특히 키입력부에 스트레오음악방송자동선국키를 구비하여 시청자가 스트레오 음악방송을 시청하고자 할 때에 해당키를 누르면 자동으로 스트레오 방송을 탐색, 선구할 수 있도록 한 텔레비전 수상기의 스트레오음악방송자동선국장치 및 그 방법에 관한 것이다.The present invention relates to a television receiver function of stereo music broadcasting, and in particular, when the viewer has a stereo music broadcasting automatic tuning key and presses the corresponding key when the viewer wants to watch stereo music broadcasting, the stereo broadcasting is automatically searched and pioneered. The present invention relates to a stereo music broadcasting automatic tuning apparatus for a television receiver and a method thereof.

본 발명은 스트레오음성신호에 포함되어 있는 스트레오파일롯트신호를 검출하여 마이크로프로세서(11)에 검출신호를 인가하도록 된 파일롯트신호검출부(30)를 추가로 구비하여;키 입력부(9)로부터의 신호에 의하여 스트레오음악방송자동선국모드가 선택되는지를 판단하여, 스트레오음악방송자동선국모드가 선택되었을 경우에 파일롯트신호검출부(30)로부터의 신호에 의해서 현 채널의 음성신호에 파일롯트신호가 포함되어 있는지를 판단하고, 현채널의 음성신호에 파일롯트신호가 포함되어 잇지 않을 경우에 튜너(3)를 제어하여 채널을 한단계 업(up)한 후, 채널이 방송신호가 있는 유효채널인 경우에 파일롯트신호검출부(30)로부터의 신호에 의해서 음성신호에 파일롯트신호가 포함되어 있는지를 판단하여, 선국된 현 채널의 음성신호에 파일롯트신호가 있을 경우에 현 채널의 방송을 출력하는 것을 특징으로 한다.The present invention further includes a pilot signal detection unit 30 configured to detect a stereo pilot signal included in the stereo audio signal and apply a detection signal to the microprocessor 11; a signal from the key input unit 9. It is determined whether or not the stereo music broadcasting automatic tuning mode is selected, and when the stereo music broadcasting automatic tuning mode is selected, the pilot signal is included in the audio signal of the current channel by the signal from the pilot signal detection unit 30. If the pilot signal is not included in the audio signal of the current channel, the tuner 3 is controlled to increase the channel one step, and then the file is stored if the channel is an effective channel with a broadcast signal. It is determined whether the pilot signal is included in the voice signal by the signal from the lot signal detection unit 30, and the pilot signal is included in the selected voice signal of the current channel. If there is, characterized in that to output the broadcast of the current channel.
