Abstract

본 발명은 디지탈 비디오 테이프 레코더의 트릭플레이를 수행하기 위한 데이타 기록방법에 관한 것으로서, 소정간격으로 공급되고 독립적으로 디코딩이 가능한 프레임 데이타들을 포함하는 ATV신호를 노말플레이 데이타와 트릭플레이 데이타로 구분하여 디지탈비디오테이프에 기록하는 방법에 있어서, 상기 디지탈 비디오 테이프의 각 트랙에 있어 비디오 섹터의 데이타 영역을 제1영역, 제2영역, 제3영역, 제4영역 및 제5영역으로 분할하고, 상기 제1영역, 제3영역 및 제5영역의 각각에는 교류성분의 트릭플레이 데이타를 기록하고, 상기 제2영역 및 제4영역의 각각에는 직류성분의 트릭플레이 데이타와 노말플레이 데이타를 혼재하여 기록하고, 상기 제1영역, 제2영역, 제3영역, 제4영역 및 제5영역에 기록된 교류성분 및 직류성분의 트릭플레이 데이타는 트랙플레이의 최대 배속의 2배에 해당하는 갯수의 트랙에 주기, 반복적으로 기록됨을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data recording method for performing trick play of a digital video tape recorder, wherein an ATV signal including frame data supplied at predetermined intervals and independently decodable is divided into normal play data and trick play data. A recording method on a video tape, comprising: dividing a data area of a video sector into a first area, a second area, a third area, a fourth area, and a fifth area in each track of the digital video tape; The trick play data of the AC component is recorded in each of the region, the third region and the fifth region, and the trick play data and the normal play data of the DC component are mixed and recorded in each of the second and fourth regions. The trick play data of the AC component and DC component recorded in the first region, the second region, the third region, the fourth region, and the fifth region is Period the number of tracks equal to twice the maximum speed of the rack play, characterized by repeatedly recorded in.

따라서, 반복적으로 트릭플레이 데이타를 기록해 주기 때문에 어느 특정 배속에 국한되지 않고, 최대 배속내의 짝수 배속 및 소수점 배속은 모두가 가능하기 때문에 사용자로 하여금 비디오 테이프 레코더의 트릭플레이에 있어 배속의 선택의 폭을 다양하게 해주는 효과가 있다.Therefore, it is possible to record trick play data repeatedly so that it is not limited to any specific speed, and even speed and decimal speed within the maximum speed can both be selected. It has a variety of effects.
