Abstract

본 발명은 PAL⁺브이씨알에서 녹화된 테이프를 일반 브이씨알에서 재생처리하는 기술에 관한 것으로, AL⁺브이씨알에 의해 PAL⁺신호가 기록된 테이프를 PAL⁺브이씨알이 아닌 일반 브이씨알에서 재생처리하는 경우 헬퍼신호의 레벨이 높게 나타나므로 이를 4:3티브이에 디스플레이하는 경우 래터박스의 상·하단에 화이트색깔로 디스플레이되어 메인 화면을 감상하는데방해가 되는 문제점이 있었는바, 본 발명은 이를 해결하기 위하여, 라인카운터(22), 수평블랭킹신호 발진기(23), 헬퍼마커(24)를 이용하여 헬퍼마커신호를 생성하고, 헬퍼킬러(21)는 그 헬퍼마커신호를 이용하여 입력복합영상신호(CVBS)에 삽입된 헬퍼신호를 삭제하며, 데이타검출부(26)의 출력신호를 이용하여 스위치(27)의 스위칭을 제어함으로서 출력단에는 헬퍼신호가 삭제된 복합영상신호를 출력하도록 하였다.The invention PAL ⁺ V a tape recorded in the CR relates to techniques for handling play in general V CR, the process reproduces the tape PAL ⁺ signal is recorded by the AL ⁺ V CR in general V CR non-PAL ⁺ V CR If the level of the helper signal is high, if the 4: 3 TV is displayed at the top and bottom of the letter box, the white color is displayed and there is a problem in that it is difficult to enjoy the main screen. In order to generate a helper marker signal using the line counter 22, the horizontal blanking signal oscillator 23, and the helper marker 24, the helper killer 21 uses the helper marker signal to input the composite video signal (CVBS). ) And deletes the helper signal inserted into the control unit, and controls the switching of the switch 27 by using the output signal of the data detection unit 26. It was to output.

Claims

A helper killer 21 for erasing the helper signal inserted into the composite video signal CVBS using the helper marker signal input from the helper marker 24 and the helper signal by counting lines of the input composite video signal CVBS. Generated by the line counter 22 and the horizontal blanking signal oscillator 23 for generating a horizontal blanking signal, the signal output from the line counter 22 and the horizontal blanking signal oscillator 23. A helper marker 24 for synthesizing the horizontal blanking signal to generate a helper marker signal, and a data slicer 25 for slicing the composite video signal CVBS to detect the wide screen signal WSS on line 23; The data detector 26 outputs a switching control signal based on the bi-phase coded widescreen signal WSS output from the data slicer 25 and the helper section under the control of the data detector 26. VP's helper signal killer comprising an output signal of the helper killer 21 and a switch 27 for selecting and outputting a signal input through the composite video signal (CVBS) terminal in other sections. Device.
