Abstract

본 발명은 무신호 채널 선택시 주화면과 주음성 출력동작 제어방법에 관한 것으로, 종래에는 업/다운 키나 숫자키를 이용하여 다른 채널을 선국하는 중에 방송신호가 수신되는 채널로 절환되는 경우에는 화면으로 방송신호가 출력되나, 무신호 즉, 방송신호가 수신되지 않는 채널을 선국한 경우에는 화면에 노이즈만 출력되고 이에 대응되게 주음성 스피커로는 잡음만이 출력되기 때문에 불쾌감을 주는 결점이 있었다. 본 발명은 주화면으로 수신되는 방송신호의 채널을 절환하기 위한 키 입력이 있으면 키 입력에 의해 절환된 채널의 방송신호가 무선신호인가를 판단하고 판단결과 절환된 채널의 방송신호에 동기신호가 포함되어 있으면 절환된 채널의 방송신호를 정상적으로 선국하여 주화면과 주음성을 출력하지만 절환된 채널의 방송신호에 동기신호가 포함되어 있지 않으면 텔레비젼 수상기의 PIP 기능을 동작시켜 절환된 채널의 방송신호를 선국하여 주화면으로 출력하고 절환되기 이전에 주화면으로 출력되던 채널의 음성신호를 주음성으로 출력함으로서, 텔레비젼 수상기의 채널을 무신호가 입력되는 채널로 절환한 경우 메인 스피커로 잡음이 출력되는 것을 방지할 수 있는 것이다.The present invention relates to a main screen and a main audio output control method for selecting a non-signal channel, and conventionally, when switching to a channel for receiving a broadcast signal while selecting another channel using an up / down key or a numeric key, When a broadcast signal is output, but no signal, that is, when a channel in which a broadcast signal is not received is tuned, only noise is output on the screen, and correspondingly, only noise is output to the main audio speaker. According to the present invention, if there is a key input for switching a channel of a broadcast signal received on the main screen, it is determined whether the broadcast signal of the channel switched by the key input is a wireless signal, and the determination result includes a synchronization signal in the broadcast signal of the switched channel. If the broadcast signal of the switched channel is normally selected, the main picture and the main audio are output normally, but if the broadcast signal of the switched channel does not include the synchronization signal, the PIP function of the television receiver is operated to tune the broadcast signal of the switched channel. By outputting to the main screen and outputting the audio signal of the channel that was output to the main screen before switching to the main audio, when the channel of the television receiver is switched to the channel to which no signal is input, noise is prevented from being output to the main speaker. It can be.

숫자키나 채널 업/다운 키의 입력에 따라 다른 채널의 방송신호를 수신 처리함에 있어서, 주화면으로 수신되는 방송신호의 채널을 절환하기 위한 키 입력을 감시하는 단계와: 상기 단계에서 주화면으로 출력되는 방송신호의 채널을 절환하기 위한 키 입력이 있으면 키 입력에 의해 절환된 채널의 방송신호가 무선신호인가를 판단하는 단계와: 키 입력으로 절환된 채널의 방송신호에 동기신호가 포함되어 있으면 절환된 채널의 방송신호를 선국하여 주화면과 주음성을 출력하는 단계와: 키 입력으로 절환된 채널의 방송신호에 동기신호가 포함되어 있지 않으면 텔레비젼 수상기의 PIP 기능을 동작시켜 절환된 채널의 방송신호를 선국하여 주화면으로 출력하고 절환되기 이전에 주화면으로 출력되던 채널의 음성신호를 주음성으로 출력하는 단계를 수행하도록 이루어짐을 특징으로 하는 무신호 채널 선택시 주화면과 주음성 출력동작 제어방법.Monitoring a key input for switching a channel of a broadcast signal received on a main screen in receiving and processing a broadcast signal of another channel according to input of a numeric key or a channel up / down key: outputting to the main screen in the step Determining whether the broadcast signal of the channel switched by the key input is a radio signal if there is a key input for switching a channel of the broadcast signal to be switched: switching if the broadcast signal of the channel switched by the key input includes a synchronization signal Tuning the broadcast signal of the channel to output the main picture and the main audio; and if the broadcast signal of the channel switched by key input does not include a synchronization signal, operates the PIP function of the television receiver to switch the broadcast signal of the switched channel. And outputting to the main screen and outputting the audio signal of the channel output to the main screen before the switching to the main voice. So that the no-signal channel, characterized in yirueojim the main screen and the main audio output operation control method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
