Abstract

본 발명은 플레이백기능을 갖는 다중화면 디스플레이장치에 관한 것으로, 메모리를 이용하여 이전 영상신호를 저장하였다가, 플레이백기능이 선택되면, 주화면은 현재 수신되는 방송신호를 그대로 디스플레이하면서, 부화면은 플레이백기능키가 입력되기 전까지의 일정 기간의 메모리에 기억시킨 화면을 디스플레이하도록하여 텔레비젼으로 방송신호를 시청할 때, 인상적인 장면들이 지나간 경우 VTR의 녹화기능을 사용하지 않고, 텔레비젼 자체의 플레이백기능을 사용하여 지나간 화면을 재생시켜 볼 수 있는 잇점을 제공한다.The present invention relates to a multi-screen display device having a playback function. When a previous video signal is stored using a memory and a playback function is selected, the main screen displays the currently received broadcast signal as it is, When a user watches a broadcast signal on a television so as to display a screen stored in a memory for a predetermined period before the playback function key is input, when the impressive scenes are passed, the VTR's recording function is not used, It is possible to reproduce the past screen.
