녹화키 입력시 일반 녹화 모우드를 수행하는 VCR에 있어서, 인터럽트 녹화키 입력을 체크하고 일정시간 픽쳐 서어치 모우드를 수행하며 복합 동기 신호 입력을 판단하는 복합 동기 신호 판단 단계와, 상기 복합 동기 신호 판단 단계에서 복합 동기 신호가 검출되지 않으면 짧은 시간 되감기 모우드를 수행시킨 후 복합 동기 신호가 검출될 때 녹화 모우드를 수행시키는 단계와, 상기 복합 동기 신호 판단 단계에서 복합 동기 신호가 검출되면 빨리 보내기 모우드를 수행시킨 후 콘트롤 펄스 입력을 판단하는 콘트롤 펄스 판단 단계와, 상기 콘트롤 펄스판단 단계에서 콘트롤 펄스 입력이 없게 되면 짧은 시간 되감기 모우드를 수행시킨 후 콘트롤 펄스가 검출될 때 녹화 모우드를 수행시키는 단계를 포함하여 이루어진 것을 특징으로 하는 녹화시 프로그램 보호방법.In a VCR that performs a normal recording mode when a recording key is input, a composite synchronization signal determination step of checking an interrupt recording key input, performing a picture search mode for a predetermined time, and determining a composite synchronization signal input, and determining the composite synchronization signal If the composite synchronization signal is not detected in the step of performing a short time rewind mode and performing a recording mode when the composite synchronization signal is detected, and if the composite synchronization signal is detected in the composite synchronization signal determination step to perform a fast send mode And a control pulse determination step of determining a control pulse input after the control pulse, and performing a short time rewind mode when there is no control pulse input in the control pulse determination step, and then performing a recording mode when the control pulse is detected. Program at the time of recording characterized by Call method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
