Abstract

본 발명은 PIP 동작모드 절환시 화면과 음성 출력동작 제어방법에 관한 것으로, 종래에는 특정채널의 방송신호를 시청하는 중이나 부화면으로 특정 채널의 방송신호를 시청하는 중에 텔레비젼 수상기의 동작모드가 PIP 동작모드로 절환되거나 부화면의 채널이 절환되는 경우 절환되기 이전에 출력되던 채널의 방송신호 내용을 전혀 알 수 없다는 단점을 가지고 있었다. 본 발명은 특정 채널의 방송신호를 주화면으로 출력하거나 부화면으로 특정 채널의 방송신호를 출력하면서 채널을 절환하기 위한 키 입력을 감시하여 텔레비젼 수상기의 동작모드를 PIP 동작모드로 절환하거나 부화면으로 출력되던 채널이 절환되면 절환된 채널의 영상신호를 주화면으로 출력하고 절환되기 이전에 주화면 혹은 부화면으로 출력되던 채널의 음성신호를 주음성으로 출력함으로서, 텔레비젼 수상기의 동작모드가 PIP 동작모드로 절환되거나 혹은 PIP 동작을 수행하는 중에 부화면의 채널이 절환되어도 절환되기 이전에 주화면이나 부화면으로 출력되던 채널의 음성신호를 주음성으로 확인할 수 있는 효과가 있다.The present invention relates to a method of controlling a screen and an audio output operation when switching a PIP operation mode, and in the related art, an operation mode of a television receiver is a PIP operation while watching a broadcasting signal of a specific channel or watching a broadcasting signal of a specific channel. When switching to the mode or the channel of the sub-screen is switched has a disadvantage that the contents of the broadcast signal of the channel that was output before the switching is not known at all. The present invention monitors a key input for switching a channel while outputting a broadcast signal of a specific channel to a main screen or outputting a broadcast signal of a specific channel to a sub picture, thereby switching the operation mode of the television receiver to a PIP mode or to a sub picture. When the output channel is switched, the video signal of the switched channel is output to the main screen, and the audio signal of the channel that was output to the main screen or sub-screen before the switching is output as the main audio, so that the operation mode of the television receiver is the PIP operation mode. Even if the sub-channel is switched during the PIP operation or the PIP operation, the audio signal of the channel that was output to the main screen or sub-screen before switching is effective as the main voice.

Claims

Switching channels while outputting the broadcasting signal of a certain channel by the channel up / down key or the numeric key operation and outputting the broadcasting signal of a specific channel on the main screen or the broadcasting signal of the specific channel on the sub screen. Monitoring the key input for: switching the operation mode of the television receiver to the PIP operation mode or switching the channel output on the sub-screen, and outputting the video signal of the switched channel to the main screen before the switching. The control method of the screen and the voice output operation when switching the PIP mode, characterized in that the step of outputting the voice signal of the channel output to the screen or sub-screen to the main voice.
