Abstract
본 발명은 텔레비젼 수상기의 채널 절환시 음성신호 출력동작 제어방법에 관한 것으로, 종래에는 텔레비젼 수상기를 시청하던 중에 리모콘이나 기타 입력장치 오동작시켜 텔레비젼 수상기의 채널이 절환되거나 탐색용 키를 절환한 경우에는 시청중이던 채널의 방송신호가 차단되기 때문에 기존에 시청중인 방송신호를 확인하지 못하는 결점을 가지고 있었다. 본 발명은 메인전원이 공급되면 기선국된 채널의 방송신호를 선국하여 주화면과 주음성으로 출력하면서 키 입력에 따른 채널 절환상태를 확인하여 방송신호의 채널이 절환되면 텔레비젼 수상기의 동작모드를 PIP 동작모드로 절환시켜 기존에 시청하던 채널의 음성신호를 주음성으로 출력하고 절환된 채널의 영상신호를 주화면으로 출력하고, 이를 일정시간 실행한후 절환된 채널의 음성신호와 영상신호를 주음성과 주화면으로 출력함으로서, 특정채널의 방송신호를 시청하면서 다른 채널의 방송신호를 탐색하는 경우 혹은 채널 절환키를 오동작시킨 경우 기존에 시청중인 채널의 방송신호를 확인할 수 있는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of controlling a voice signal output operation during channel switching of a television receiver. In the related art, when a channel of a television receiver is switched or a search key is switched due to malfunction of a remote controller or other input device while watching a television receiver. Since the broadcast signal of the channel being used is blocked, it has a drawback of not being able to check the broadcast signal being viewed. According to the present invention, when the main power is supplied, the broadcast signal of the pre-selected channel is tuned to the main screen and the main audio, and the channel switching state according to the key input is checked. Switch to the operation mode to output the audio signal of the previously watched channel as the main audio, and output the video signal of the switched channel to the main screen, and after executing this for a predetermined time, the audio signal and the video signal of the switched channel are the main audio. By outputting to the main screen, when a broadcast signal of a specific channel is searched while watching a broadcast signal of a specific channel or when a channel switching key is malfunctioned, the broadcast signal of a previously viewed channel can be checked.
