Abstract

본 발명은 비디오 카세트 레코더(VIDEO CASSETTE RECORDER )의 절환 방법에 관한 것으로서, 더욱 상세하게는 설정된 컬러방식(Color System)과 입력되는 신호 또는 재생 신호의 컬러 방식이 다를 경우 자동적으로 컬러 방식 모드를 절환시키는브이씨알의 자동 절환 방법에 관한 것이다.The present invention relates to a method of switching a video cassette recorder (VIDEO CASSETTE RECORDER), and more particularly, to automatically switch the color mode when the set color system (Color System) and the color system of the input signal or reproduction signal is different. It is about automatic switching method of V-seal.

이를 위하여 본 발명은, 수직 동기 신호 및 변화하는 컬러 킬러 전압을 이용하여 컬러 방식 모드를 절환하는 브이씨알의자동 절환 방법으로서, 플레이키 신호가 입력되었는가를 판단하는 과정(200); 플레이키 신호가 입력되었으면 NTSC 방식모드로 설정하고(201), PAL-N 방식에 대한 수직 동기 신호가 입력되었는가 판단하는 과정(202); PAL-N 방식의 수직 동기신호가 입력되었으면 PAL-N 방식으로 설정하는 과정(203); PAL-N 방식의 수직 동기 신호가 입력되지 않았으면, 로우 레벨의 킬러 신호가 입력되는가를 판단하는 과정(204); 로우 레벨의 킬러 신호가 입력되면 NTSC 방식으로 설정하는 과정(205); 로우 레벨의 킬러 신호가 입력되지 않았으면 하이 레벨의 킬러 신호가 입력되는가를 판단하는 과정(206); 하이 레벨의 킬러 신호가 입력되었으면 강제 모드로 설정하는 과정(207); 하이 레벨의 킬러 신호가 입력되지 않았으면 PAL-M 방식으로 설정하는 과정(208)을 포함하도록 구성하여, 소프트 웨어적으로 컬러 방식 모드를 자동으로 절환하므로써 별도의회로를 추가하지 않아도 되는 이점이 있다.To this end, the present invention provides a method of automatic switching of V-CAL to switch the color mode using a vertical synchronization signal and a changing color killer voltage, the method comprising: determining whether a playkey signal is input (200); If the playkey signal is input, set to the NTSC mode (201), and determining whether a vertical synchronization signal for the PAL-N method is input (202); Setting the PAL-N method to the PAL-N method when the vertical synchronization signal is input (203); If the vertical synchronization signal of the PAL-N method is not input, determining whether a low-level killer signal is input (204); If the low-level killer signal is input, setting the NTSC method (205); Determining whether a high-level killer signal is input if the low-level killer signal is not input (206); Setting a forced mode when a high-level killer signal is input (207); If the high-level killer signal is not input, it is configured to include the step 208 of setting the PAL-M method, and there is an advantage of not needing to add a separate circuit by automatically switching the color mode in software. .
