Abstract

본 발명은 디지탈 비디오 테이프의 기록방법에 관한 것으로, 소정 간격으로 공급되고 독립적으로 디코딩이 가능한 I-프레임 데이타들을 포함하는 ATV신호를 노말플레이 데이타와 트릭플레이 데이타로 구분하여 디지탈 비디오 테이프에 기록하는 방법에 있어서, ATV신호를 노말플레이 데이타와 트릭플레이 데이타로 구분하여 노말플레이를 위한 데이타들을 트랙들의 각 비디오 섹터와 오디오 섹터에 나누어 기록하고, 트릭플레이를 위해 선택된 I-프레임 데이타들을 트랙들의 각 비디오 섹터의 소정의 위치에 기록하는 것을 특징으로 한다. 따라서, 본 발명은 오디오 데이타 영역에 노말데이타를 기록하므로서 트릭플레이 데이타를 기록하기 위한 비디오 트랙의 싱크영역을 보다 많이 확보하는 장점이 있다.The present invention relates to a method for recording a digital video tape, comprising: dividing an ATV signal including I-frame data that is supplied at predetermined intervals and independently decodable into normal play data and trick play data to record on a digital video tape In A, the ATV signal is divided into normal play data and trick play data, and data for normal play is recorded in each video sector and audio sector of tracks, and the selected I-frame data for trick play is recorded in each video sector of tracks. It is characterized in that the recording at a predetermined position. Accordingly, the present invention has the advantage of securing more sync area of a video track for recording trick play data by recording normal data in the audio data area.
