Abstract

본 발명은 영상신호 제생장치에 있어서, 신호가 결탁되어 있거나 재생된 영상신호에 심한 잡음이 발생될 때 기록매체로부터 재생된 영상신호를 뮤팅시키고 배경색을 화면상에 출력하는 장치에 관한 것으로, 정상재생모드에서 정지 또는 일시정지모드가 선택되었을 때 배경화면 신호를 발생하는 배경화면 발생부와; 상기 기록매체로부터의 재생신호와 배경화면 발생부로부터의 배경화면신호를 절환하기 위한 스위칭수단과; 상기 모드선택 수단으로부터 입력된 모드선택신호를 검지하여 상기 스위칭수단으로 절환신호를 인가하는 제어수단; 및 상기 제어수단으로부터 스위칭수단으로 인가되는 절환신호에 응답하여 리세트신호를 발생하여 상기 배경화면 발생부로 인가하는 리세트 신호 발생수단을 포함하여 구성되는 것을 특징으로 한다. 따라서, 배경화면 발생부의 수직동기신호를 모드절환과 동시에 리세트시킴으로써 모드 절환시 화면의 일시적인 깨짐을 방지할 수 있다.The present invention relates to an apparatus for muting an image signal reproduced from a recording medium and outputting a background color on a screen when a signal is condensed or severe noise is generated in the reproduced image signal. A background image generator for generating a background image signal when a stop or pause mode is selected in the mode; Switching means for switching a reproduction signal from the recording medium and a background image signal from a background image generator; Control means for detecting a mode selection signal input from said mode selection means and applying a switching signal to said switching means; And a reset signal generating means for generating a reset signal in response to a switching signal applied from the control means to the switching means and applying the reset signal to the background screen generator. Therefore, by temporarily resetting the vertical synchronization signal of the background image generating unit at the same time as the mode switching, it is possible to prevent the screen from being temporarily broken during the mode switching.
