연속되는 입력이미지들을 기록캐리어상에 순차적으로 기록되는 복수의 동기블록들로 압축인코딩하는 방법 및 장치는 제1이미지 압축인코딩기법에 의해 각 입력이미지들을 디지탈 처리하여 각 입력이미지들의 저해상도 버젼을 나타내는 제1디지탈 신호를 제공한다. 상기 입력이미지들 또한 상기 제1이미지 압축인코딩기법과 다른 제2이미지 압축인코딩기법에 의해 디지탈처리되어 각 입력이미지들의 보다 높은 고해상도 버젼을 나타내는 제2디지탈신호를 제공한다. 상기 제1디지탈 신호 및 제2디지탈 신호 모두의 연속부분들은 합성되어 기록캐리어상에 기록되는 순차동기블록들로 된다. A method and apparatus for compression encoding successive input images into a plurality of sync blocks which are sequentially recorded on a record carrier, comprises digitally processing each of the input images in accordance with a first image compression encoding technique so as to provide a first digital signal representative of a low resolution version of each of the input images. The input images are also digitally processed in accordance with a second image compression encoding technique which is different from the first image compression encoding technique so as to provide a second digital signal representative of a higher resolution version of each of the input images. Consecutive portions of both of the first and second digital signals are combined into sequential sync blocks which are then sequentially recorded on a record carrier.
