Abstract

본 발명은 무신호상태에서의 다양한 배경화면을 제공하는 VTR에 관한 것이다. 본 발명의 VIR은 여러 가지 색상의 배경화면 및 그림을 저장하고 있는 메모리와 원하는 배경화면을 선택하기 위한 선택스위치와, 라인상의 입력 영상신호에 대한 무신호상태를 판단하기 위하여 입력 영상신호의 동기를 검출하는 동기검출기와, 테이프 재생신호에 대한 무신호상태를 판단하기 위하여 재생신호의 엔벨로프를 검출하는 엔벨로프검출기와, 동기검출여부와 엔벌로프검출여부를 통해 무신호상태를 판단하고, 무신호상태로 판단되면 초기 설정한 배경화면 제공을 위한 제어신호를 일단 발생하며, 선택 스위치에 의해 선택된 배경화면 제공을 위한 제어신호를 발생하는 마이콤과, 제어신호에 따라 구동하여 모니터상에 청색 배경화면을 현시하고 메모리에 저장된 배경화면들중 해당하는 하나를 모니터상에 현시하는 OSP-IC로 구성된다. 따라서, 본 발명은 사용자에게 다양한 배경화면을 제공할 수 있어 사용자의 만족도를 향상시킬 수 있는 효과를 제공한다.The present invention relates to a VTR that provides various background screens in a no-signal state. The VIR of the present invention includes a memory for storing background pictures and pictures of various colors, a selection switch for selecting a desired background image, and a controller for selecting a synchronization mode of the input image signal in order to determine a non- An envelope detector for detecting an envelope of a reproduction signal for determining a non-signal state with respect to the tape reproduction signal, and a non-signal state determination unit for determining whether the synchronization signal is not detected or whether an envelope is detected, A microcomputer which once generates a control signal for providing an initially set background screen and generates a control signal for providing a background screen selected by the selection switch and a blue background screen on the monitor driven by the control signal, And an OSP-IC that displays one of the background screens stored in the memory on the monitor. Accordingly, the present invention provides a variety of background images to the user, thereby improving the user's satisfaction.
