Particularly, the present invention includes a sub-screen music broadcasting automatic tuning key in a key input unit so that a viewer can broadcast music on a sub-screen. The present invention relates to a sub picture music broadcasting automatic tuning circuit of a television receiver and to a method for automatically searching for and tuning a music broadcast of a sub picture channel when a corresponding key is pressed when watching.

본 발명은 부화면방송의 음성신호에서 파일롯트신호를 검출하여 마이크로프로세서(11)에 검출신호를 인가하도록 된 파일롯트신호검출부(30)를 추가로 구비하여: 키입력부(9)로부터의 신호에 의해서 PIP 모드 및, 부화면음악방송자동선국모드가 선택되는지를 판단하여, 상기 모드들이 선택되었을 경우에 파일롯트신호검출부(30)로부터의 신호에 의해서 현 부화면채널의 음성신호에 파일롯트신호가 포함되어 있는지를 판단하여, 현 부화면채널의 음성신호에 파일롯트신호가 포함되어 있지 않을 경우에 서브튜너(3b)를 제어하여 부화면채널을 한단계 업(up)하며, 다시 파일롯트신호검출부(30)로부터의 신호에 의해서 부화면음성신호에 파일롯트신호가 포함되어 있는지를 판단하여, 선국된 현 부화면채널의 음성신호에 음악방송의 파일롯트신호가 있을 경우에 현 부화면채널의 음악방송을 출력하는 것을 특징으로 한다.The present invention further includes a pilot signal detection unit 30 configured to detect a pilot signal from the audio signal of the sub picture broadcast and apply the detection signal to the microprocessor 11: to a signal from the key input unit 9. It is determined whether the PIP mode and the sub picture music broadcasting automatic tuning mode are selected, and when the modes are selected, the pilot signal is added to the voice signal of the current picture 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 sub picture channel, the sub-tuner 3b is controlled to increase the sub picture channel by one step, and again the pilot signal detection unit ( It is determined whether the pilot signal is included in the sub-screen audio signal based on the signal from 30), and if the pilot signal of the music broadcast is included in the voice signal of the selected current screen channel. Characterized in that for outputting a music program of the current channel display part.
