Abstract

연속적인 입력이미지들을 입력기록캐리어상에 순차적으로 기록된 복수개의 동기블록으로 압축코딩하는 방법 및 장치는 제1이미지 압축인코딩기술에 따라서, 상기 입력이미지들의 각각을 디지탈적으로 처리하여 상기 입력된 이미지들의 각각의 저해상도버젼을 나타내는 제1디지탈신호를 제공하는 것을 특징으로 한다. 상기 입력이미지들은 또한 상기 제1이미지 압축인코딩기술과 상이한 제2이미지 압축인코딩기술에 따라서 디지탈적으로 처리되어, 상기 입력이미지들의 각각의 더 높은 해상도 버젼을 나타내는 제2디지탈신호를 제공한다. 상기 제1 및 제2디지탈신호들의 연속적인 부분은 그 다음 기록캐리어상에 순차적으로 기록된 순차동기블록들로 결합된다. 평균적으로, 각 동기블록의 제1디지탈신호는 상기 입력이미지의 완전한 수평라인을 나타낸다.

Description

고속화상재생에 적합한 디지탈비디오테이프레코더용 테이프상의 데이타 배치기술
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제2도는 본 발명에 따른 디지탈 VTR에서 사용되는 압축부호화 알고리즘을 수행하는 장치의 블록도, 제3도는 제2도의 장치에 사용되는 서브밴드 디콤포지션(dec omposition) 및 데시메이션(decimation)을 설명하기 위한 도면, 제5도는 본 발명의 원리에 의한 자기테이프상에 제4도에 도시한 동기블록의 배치 및 복원하는 과정을 도시하는 도면.

Claims (2)

  1. 각 동기블록이 그 안에 부호화된 제1 및 제2디지탈신호들을 갖는 적어도 제1 및 제2부분으로 분할되고, 상기 제1디지탈신호가 트릭플레이모드 중에 입력이미지를 복원하는데 사용되고, 상기 제2디지탈신호는 모말플레이모드 중에 입력이미지를 복원하는데 사용하며, 평균하여, 각 동기블록의 상기 제1디지탈신호는 상기 입력이미지의 완전한 수평라인을 나타내는 것을 특징으로 하고, 그 안에 기록된 복수개의 평균 경사트랙들을 포함하는 이미지캐리어.
  2. 제1항에 있어서, 상기 제1신호는 상기 입력이미지의 저해상도 버젼을 나타내는 제1디지탈신호를 공급할 수 있도록 제1이미지 압축인코딩기술에 따라서 상기 입력이미지를 디지탈적으로 처리함으로써 발생되고, 상기 제2신호는 상기 입력이미지의 더 높은 해상도 버젼을 나타내는 제2디지탈신호를 공급할 수 있도록 상기 제1이미지 압축인코딩기술과는 상이한 제2이미지 압축인코딩기술에 따라서 상기 입력이미지를 디지탈적으로 처리함으로써 발생되는 것을 특징으로 하는 이미지캐리어.
