Abstract

본 발명은, 미니디스크에, MPEG 규격들에 기초해서 고능률 부호화된 화상 데이타를 일정수의 섹터마다 클러스터화 하고, 각 클러스터의 접속부분에 링크 섹터를 설치하고, 인터리브 처리를 실시해서 기록할 즈음에, 그 화상 데이타를, IGOP를 단위로 해서, 각 클러스터에 각각 기록한다. 미니 디스크가 재생 전용이며, 클러스터의 선두에 P화상 과 따로 I화상으로서 부호화해서 기록해 놓는다. 복호시 직전의 클러스터의 링크 섹터에, I화상이 기록되어 있지 않은 경우, 클러스터이 선두의 P화상 또는 B화상의 실질적인 복호를 금지한다. 이것에 따라, 고능률 부호화된 화상 데이타를, 미니디스크 등의 디스크형 기록 매체에 기록할 즈음에, GOP를 단위로 하는 편집 처리를 간단하고도 매우 신속하게 처리함으로써 가능하게 됨과 함께, GOP를 단위로 하는 고속 급송이나 역송 재생들의 특수효과도 간단하고 매우 신속한 처리에 따라 가능하게 된다.
