Abstract

본 발명은 텔레비젼 수상기의 PIP 모드 자동 절환방법에 관한 것으로, 종래에는 채널 업/다운키나 숫자키를 조작하여 다른 채널을 탐색하는 경우 선국된 채널의 방송신호가 계속해서 바뀌면서 디스플레이되기 때문에 시청자는 이를 보고 다른 채널의 방송신호를 확인하므로 기존에 시청하던 방송신호를 시청하지 못하는 결점을 가지고 있었다. 본 발명은 특정 채널의 방송신호를 주화면으로 수신 출력하면서 주화면으로 출력되는 방송신호의 채널을 절환하기 위한 키가 일정시간동안 일정 횟수 이상 입력되는가를 판단하고, 그 결과 일정 횟수 이하로 입력되면 선택된 채널의 방송신호를 선국하여 주화면과 주음성으로 출력하고 일정 횟수 이상으로 입력되면 텔레비젼 수상기의 PIP 동작모드를 동작시켜 절환된 채널 중 특정 채널의 영상신호와 음성신호를 주화면과 주음성으로 출력하면서 계속해서 입력되는 채널 절환키에 의해 선국된 채널의 영상신호와 음성신호를 부화면과 부음성으로 출력함으로서, 기존에 시청하던 방송신호를 시청하면서 타채널로 입력되는 방송신호를 탐색할 수 있는 것이다.The present invention relates to a method of automatically switching the PIP mode of a television receiver. In the related art, when a user searches for another channel by operating a channel up / down key or a numeric key, the viewer reports the broadcast signal of the tuned channel continuously while being displayed. Since the broadcast signal of another channel is checked, there is a drawback of not being able to watch the broadcast signal that was previously viewed. The present invention determines whether a key for switching a channel of a broadcast signal output to the main screen is input a predetermined number of times or more during a predetermined time while receiving and outputting a broadcast signal of a specific channel to the main screen. When the broadcast signal of the selected channel is tuned and output to the main screen and the main voice, and the input signal is input for a predetermined number or more, the PIP operation mode of the television receiver is operated to convert the video signal and the audio signal of a specific channel among the switched channels into the main screen and the main audio. By outputting the video signal and audio signal of the channel selected by the channel switching key which is continuously input while outputting, the sub-screen and sub-audio can be used to search for a broadcast signal input to another channel while watching the broadcast signal that has been previously watched. It is.

Claims

A key for switching the channel of a broadcast signal output to the main screen while receiving and outputting the broadcast signal of a specific channel to the main screen in selecting and outputting a broadcast signal of an arbitrary channel according to the operation of the channel up / down key or the numeric keys. Monitoring an input; determining whether a key input for switching a channel of a broadcast signal output to the main screen is input for a predetermined number of times during a predetermined time; Selecting a signal and outputting it to the main screen and the main audio: when inputted more than a predetermined number of times, the PIP operation mode of the television receiver is operated to output the video and audio signals of a specific channel among the switched channels to the main screen and the main audio; The video signal and audio signal of the channel tuned by the channel switching key input continuously are output to the sub picture and sub audio. PIP mode automatic switching method of a television receiver, characterized in that is performed to perform the steps.
