Abstract

본 발명은 코트롤 신호를 이용하여 비디오 테이프에 기록된 프로그램의 목록을 디스플레이하고, 랜덤하게 재생할 수 있도록 한 비디오 카세트 레코더에서의 랜덤 재생을 위한 비디오 테이프 및 재생 방법에 관한 것으로서, 본 발명에 따른 비디오 카세트 레코더에서의 랜덤 재생을 위한 비디오 테이프는, 비디오 카세트 레코더에서 정상적인 제1콘트롤 펄스와 상기 제1콘트롤 펄스와 듀티(Duty)가 상이한 비스(VISS)용 제2콘트롤 펄스를 이용하여 랜덤 재생 및 프로그램 정보를 디스플레이할 수 있도록 하는 비디오 테이프로서, 비디오 테이프에 기록되어 있는 다수의 프로그램의 제목 및 그 기록 순서를 알리는 인덱스가 상기 제1,2콘트롤 펄스의 조합으로 코드화되어 기록되어 있는 시작 콘트롤 트랙 영역과; 상기 프로그램들이 각각 기록되어 있는 비디오 테이프의 콘트롤 트랙에는 상기 해당 프로그램의 순서 알리는 인덱스와 상세 프로그램 정보가 상기 제1,2콘트롤 펄스의 조합으로 코드화되어 각각 기록되어 있는 다수의 콘트롤 트랙 영역을 포함한다.The present invention relates to a videotape and a playback method for random playback in a video cassette recorder, which is capable of displaying a list of programs recorded on a videotape using a coat roll signal and enabling random playback, the video according to the present invention. The video tape for random playback in a cassette recorder may be randomly reproduced and programmed using a normal first control pulse in a video cassette recorder and a second control pulse for VIS that differs in duty from the first control pulse. A video tape for displaying information, comprising: a start control track area in which titles of a plurality of programs recorded on the video tape and an index indicating the recording order thereof are coded and recorded by a combination of the first and second control pulses; ; The control track of the videotape in which the programs are recorded, respectively, includes a plurality of control track areas in which an index indicating the order of the corresponding program and detailed program information are coded by a combination of the first and second control pulses.

또한, 본 발명에 따른 비디오 카세트 레코더에서의 재생 방법은, 프로그램 제목과 인덱스가 실린 콘트롤 트랙 영역과 인덱스와 세부 프로그램 정보가 실린 각각의 콘트롤 트랙 영역을 포함하는 랜덤 재생을 위한 비디오 테이프를 이용하여 사용자의 선택에 의거하여 프로그램 정보를 디스플레이 및 랜덤하게 재생하는 방법으로서, 재생 모드일 경우에 상기 비디오 테이프의 프로그램 제목과 인덱스가 기록되어 있는 콘트롤 트랙을 스캐닝하여 상기 프로그램 제목과 인덱스를 검출하는 단계와; 상기 프로그램 제목과 인덱스가 검출되면 검출된 프로그램 제목과 인덱스를 저장하는 단계와; 재생시 상기 인덱스가 검출되면 인덱스 다음에 기록되어 있는 세부프로그램 정보를 검출하여 디스플레이하는 단계와; 상기 프로그램 제목을 보기 위한 목록 키입력이 있는지를 감지하는 목록키 입력이 있으면 저장된 프로그램 제목과 인덱스를 독출하여 디스플레이하는 단계를 포함한다.In addition, a playback method in a video cassette recorder according to the present invention comprises a user using a video tape for random playback including a control track area containing a program title and an index and a respective control track area containing an index and detailed program information. A method of displaying and randomly displaying program information based on selection of a method, the method comprising: scanning a control track in which a program title and an index of the videotape are recorded in a playback mode, and detecting the program title and index; Storing the detected program title and index when the program title and index are detected; Detecting and displaying detailed program information recorded after the index when the index is detected during playback; Reading and displaying a stored program title and an index if there is a list key input for detecting a list key input for viewing the program title.
