Abstract

본 발명은 본인 또는 제3자의 실수 또는 고의로 비디오 테이프상에 기록된 중요한 영상신호가 지워지는 것을 방지하기 위해 암호입력에 의한 영상신호 이레이즈 방지를 위한 신호기록 및 재생방법에 관한 것으로서, 영상 신호 기록키 입력시 소정의 디스플레이장치에 암호입력메뉴가 디스플레이되는 암호입력메뉴 디스플레이단계; 상기 디스플레이장치에 암호를 입력하는 암호입력단계; 상기 암호입력단계에서 입력된 암호데이타를 부호화하는 암호데이타 부호화단계; 상기 암호데이타 부호화단계에서 부호화된 암호데이타와 디폴트(default)값으로 셋팅되어 있는 암호데이타를 비교하여 일치여부를 판단단계에서 판단된 결과가 불일치하면 상기 암호입력메뉴 디스플레이단계로 다시 가고, 상기 암호데이타 일치여부 판단단계에서 판단된 결과가 일치하면 신호기록을 수행하는 신호재생단계를 포함한다.The present invention relates to a signal recording and reproducing method for preventing image signal erasing by a password input in order to prevent an important video signal recorded on a videotape from being accidentally or intentionally made by a person or a third party. A password input menu display step of displaying a password input menu on a predetermined display device when a key is input; A password input step of inputting a password into the display device; An encryption data encoding step of encoding the encryption data input in the encryption input step; When the encryption data encoded in the encryption data encoding step and the encryption data set as a default value are compared and the result determined in the determination step is inconsistent, the display returns to the encryption input menu display step. And a signal reproducing step of performing signal recording when the result determined in the coincidence determination step is matched.

따라서, 본인 또는 타인의 실수나 고의로 중요한 내용이 기록되어 있는 테이프를 지우지 못하도록 하는 효과를 제공한다.Therefore, it provides an effect of preventing the tape on which the important contents are recorded by the mistake or intention of the person or others.
