Abstract

본 발명은 비디오 카세트 레코더에서의 테이프 위치 기록 방법에 관한 것으로서, 비디오 테이프의 위치를 소정 비트로 부호화하여 녹화시 비디오 테이프에 기록되는 영상 신호의 수직 귀선 소거 기간(Vertical blanking interval)내의 소정 수평 라인 구간에 1비트씩 블랭킹 레벨(Blanking level)을 변동하여 기록함으로써, 재생시 테이프의 현재 위치 인식이 용이하며, 독출된 테이프의 현재 위치를 이용하여 비디오 테이프의 잔량 또한 용이하게 계산할 수 있는 효과가 있다.The present invention relates to a method for recording a tape position in a video cassette recorder in which a position of a video tape is coded with a predetermined bit so that a video signal is recorded on a predetermined horizontal line section within a vertical blanking interval It is easy to recognize the current position of the tape at the time of reproduction, and the remaining amount of the videotape can be easily calculated by using the current position of the read tape.

Claims (5)

녹화시 영상 신호의 수직 귀선 소거 기간(Vertial Blanking Interval)내의 소정 수평 라인 구간에 비디오 테이프의 위치를 기록하는 방법으로서, 녹화 모드 전환시 로딩된 테이프에 기록되어 있는 영상 신호의 수직 귀선 소거 기간내의 소정 수평 라인 구간에 테이프의 현재 위치인 어드레스 정보가 삽입되어 있는지를 판단하는 제1단계와; 상기 어드레스 정보가 삽입되어 있으면 삽입된 어드레스 정보를 복호 처리하여 복호된 어드레스 부터 녹화 시간을 카운트하면서 카운트된 어드레스를 부호화하여 녹화되는 영상신호의 수직 귀선 소거 기간내의 소정 수평 라인 구간에 소정 주기로 삽입하여 기록하는 제2단계와; 상기 어드레스 정보가 삽입되어 있지 않으면 로딩된 테이프의 잔량을 계산하여 계산된 어드레스부터 녹화 시간을 카운트하면서 카운트된 어드레스를 부호화하여 녹화되는 영상 신호의 수직 귀선 소거 기간내의 소정 수평 라인 구간에 소정 주기로 삽입하여 기록 하는 제3단계와; 녹화가 종료되면 어드레스 정보 삽입을 정지시키고 녹화를 종료하는 제4단계를 포함하는 비디오 카세트 레코더에서의 테이프 위치 기록 방법.A method for recording a position of a video tape in a predetermined horizontal line interval within a vertical blanking interval of a video signal during recording, the method comprising: A first step of determining whether address information which is a current position of the tape is inserted in a horizontal line section; If the address information is inserted, the inserted address information is decoded, the counted address is encoded while counting the recording time from the decoded address, inserted at predetermined intervals in a predetermined horizontal line section within the vertical blanking period of the video signal to be recorded A second step of: If the address information is not inserted, the remaining amount of the loaded tape is calculated, and the counted address is encoded while counting the recording time from the calculated address. The counted address is inserted into the predetermined horizontal line section within the vertical blanking period of the video signal to be recorded A third step of recording; And stopping the insertion of the address information and ending the recording when the recording is completed. 제1항에 있어서, 상기 제1단계는 로딩된 테이프를 소정 구간 후진시키고 원위치까지 재생시키면서 독출되는 영상 신호내의 수직 귀선 소거 기간의 소정 수평 라인 구간에 어드레스 정보가 삽입되어 있는지를 판단하는 것을 특징으로 하는 비디오 카세트 레코더에서의 테이프 위치 기록 방법.2. The method as claimed in claim 1, wherein the first step is to determine whether address information is inserted in a predetermined horizontal line section of a vertical blanking period in a video signal to be read while reproducing the loaded tape back to a predetermined position Wherein the tape cassette recorder is a tape cassette recorder. 제1 또는 2항에 있어서, 상기 어드레스 정보는 헤더, 시간, 분, 초 단위로 구분되어 각각 소정 비트 스트림으로 구성되고 영상 신호의 소정 피일드의 수직 귀선 소거 기간내의 소정 수평 라인 구간에 각각 하나의 비트씩 삽입되는 것을 특징으로 하는 비디오 카세트 레코더에서의 테이프 위치 기록 방법.The method of claim 1 or 2, wherein the address information is divided into a header, a time, a minute, and a second, each of which is composed of a predetermined bit stream, Bit data is recorded in the video cassette recorder. 제3항에 있어서, 상기 어드레스 정보는 헤더, 시간, 분, 초를 나타내는 부호화된 각각 소정 비트 스트림의 행에 대한 오류를 검출하기 위한 패리티 비트를 부가하여 소정 수평 라인 구간에 삽입하는 것을 특징으로 하는 비디오 카세트 레코더에서의 테이프 위치 기록 방법.4. The method of claim 3, wherein the address information is inserted into a predetermined horizontal line section by adding a parity bit for detecting an error of a line of a predetermined bitstream, A method for recording a tape position in a video cassette recorder. 제4항에 있어서, 상기 어드레스 정보는 헤더, 시간, 분, 초를 나타내는 부호화된 각각 소정 비트 스트림의 열에 대한 오류를 검출하기 위한 체크섬 비트 스트림을 부가하여 소정 피일드의 소정 수평 라인 구간에 삽입하는 것을 특징으로 하는 비디오 카세트 레코더에서의 테이프 위치 기록 방법.5. The method of claim 4, wherein the address information is inserted into a predetermined horizontal line section of a predetermined field by adding a checksum bit stream for detecting an error in each encoded bit stream of the encoded header, time, minute, Wherein the tape cassette recorder is a tape cassette recorder. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is disclosed by the contents of the first application.
