Abstract

본 발명은 PIP기능이 내장형 텔레비전의 음성절환제어방법에 관한 것으로, 복수의 튜너에 의해 동조되는 제1텔레비전방송신호와 제2텔레비전방송신호 또는 복수의 외부비디오기기로 부터의 제1비디오신호와 제2비디오신호가 PIP기능에 의해 다화면으로 영상출력가능한 텔레비전에 있어서, PIP모드를 설정하고 주/부음성절환모드를 설정하기 전에는 주음성출력부(12)의 전력증폭에 의한 스피커(16A,16B) 및 주이어폰단자(14)를 통해서만 주화면의 영상출력에 대응하는 주음성이 출력되도록 A/V스위칭부(10)를 제어하다가, 주/부음성절환모드를 설정하게 되면 마이컴(22)은 상기 A/V스위칭부(10)에 제어신호를 인가하여 주음성출력부(12)의 전력증폭에 의한 스피커(16A,16B) 및 주이어폰단자(14)를 통해서는 부화면의 영상출력에 대응하는 부음성이 출력되도록 하고, 부음성출력부(18)의 전력증폭에 의한 부이어폰단자(20)를 통해서는 주화면의 영상출력에 대응하는 주음성이 출력되도록함으로써, 부화면에 대응하는 부음성을 청취하고자 할시에 부화면청취용 이어폰단자에 이어폰플러그를 삽입하여 청취하여야 하는 번거로움을 해결하여 시청자의 즉각적인 부음성 청취욕구를 만족시킬 수 있는 효과가 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a voice switching control method of a built-in television having a PIP function. 2 In a television capable of outputting video to a multi-screen image by the PIP function, before the PIP mode is set and the main / sub audio switching mode is set, the speaker 16A, 16B caused by the power amplification of the main audio output unit 12. Control the A / V switching unit 10 so that the main voice corresponding to the video output of the main screen is output through the main earphone terminal 14), and the main / sub audio switching mode is set. The control signal is applied to the A / V switching unit 10 to correspond to the video output of the sub-screen through the speakers 16A and 16B and the main earphone terminal 14 caused by the power amplification of the main audio output unit 12. To output negative voice Sub-screen listening when the sub-audio corresponding to the sub-screen is to be listened to by outputting the main voice corresponding to the video output of the main screen through the buoy phone terminal 20 by the power amplification of the audio output unit 18. There is an effect that can satisfy the viewer's immediate negative voice needs by solving the hassle of inserting the earphone plug into the earphone terminal for listening.
