Abstract

본 발명은 2-튜너식 텔레비전의 다화면 제어장치에 관한 것으로, 메인화면의 채널을 선국하는 제1튜너(20a)와 서브화면의 채널을 선국하기 위한 제2튜너(20a)를 구비하여 선택적으로 다화면처리가 실행되는 2-튜너식 텔레비전에서 제어신호입력부(10)의 PIP버턴(10e)에 의해 설정된 다화면 채널상태에서 상기 메인화면의 영상동기신호를 검출하는 동기신호검출부(38)와, 그 메인화면의 영상동기신호의 비검출시 활성화되어 소정시간의 계시를 수행하는 타이머(40), 그 타이머(40)에 의해 소정시간의 계시가 종료되면 영상다중처리부(32)에 의한 상기 다화면처리를 소거하는 제어부(12)를 포함하여 구성되고, 상기 제어부(12)는 상기 메인화면에 대응하는 채널에서 영상동기신호가 검출되지 않으면 상기 서브화면이 메인화면으로 전환되도록 하면서 PIP기능을 해제하도록 된 것이다.The present invention relates to a multi-screen control device for a two-tuner television, and further comprising a first tuner (20a) for tuning the channel of the main screen and a second tuner (20a) for tuning the channel of the sub-screen. A synchronization signal detection unit 38 for detecting a video synchronization signal of the main screen in a multi-screen channel state set by the PIP button 10e of the control signal input unit 10 in a two-tuner television on which multi-screen processing is performed; The timer 40 which is activated when the video synchronization signal of the main screen is not detected and performs timekeeping for a predetermined time, and when the timekeeping of the predetermined time is terminated by the timer 40, the multi-screen processing by the image multiprocessing unit 32. And a control unit 12 for canceling the control unit, and the control unit 12 releases the PIP function while switching the sub screen to the main screen when the image synchronization signal is not detected in the channel corresponding to the main screen. So will the.

Claims

In a two-tuner television having multi-screen processing selectively provided with a first tuner 20a for tuning a channel of a main screen and a second tuner 20b for tuning a channel of a sub-screen, a control signal input A synchronization signal detecting means 38 for detecting a video synchronization signal of the main screen in a multi-screen channel state set by the means 10, and activated upon non-detection of the video synchronization signal of the main screen to perform a timed display. And a control means (12) for erasing the multi-screen processing by the video multi-processing means (32) when the timer means (40) and the time-out of the predetermined time are finished by the timer means (40). The means 12 is configured to cancel the PIP function while switching the sub screen to the main screen when the video synchronization signal is not detected in the channel corresponding to the main screen. If the control unit.
