Abstract
본 발명은 비디오 테이프 초기 일정 구간의 ABL 신호를 검출하여 메모리에 기억시키고, 새로운 비디오 테이프 시청시에는 기억되어 있는 메모리 내의 데이터와 새로운 비디오 테이프의 해당구간의 ABL 신호를 비교함으로서, 기존에 보았던 테이프인지를 판단하여 사용자에게 알려주도록 하는 비디오 테이프 인지방법 및 장치를 제공함에 그 목적이 있다.The present invention detects and stores the ABL signal of the initial portion of the video tape in the memory, and compares the data in the memory stored with the ABL signal of the corresponding section of the new video tape when viewing a new video tape. It is an object of the present invention to provide a method and apparatus for recognizing a video tape to determine and notify a user.
상기한 목적을 달성하기 위한 본 발명의 방법은 텔레비전 수상기와 VCR 이 구동된 경우 데크에 삽입된 테이프가 재생 모드인가를 검색하는 VCR 상태 검색과정과; 상기 테크에 삽입된 테이프가 재생모드일 경우 소정시간 후부터 일정구간 텔레비전 수상기의 음극선관의 애노드로부터 ABL 신호를 검출 기억하여 새로운 테이프가 재생될 경우 이를 비교하여 기존에 시청한 테이프일 경우 이를 사용자에게 알려주는 기시청 테이프 인지과정으로 이루어짐을 특징으로 한다.A method of the present invention for achieving the above object includes a VCR state searching process for searching whether a tape inserted in a deck is in a playback mode when a television receiver and a VCR are driven; When the tape inserted in the tech is in the playback mode, a certain time after a predetermined time, the ABL signal is detected and stored from the anode of the cathode ray tube of the television receiver. Is characterized in that it is made by the initial recognition tape recognition process.
