Abstract

La présente invention concerne un type de procédé permettant l'enregistrement de données d'images principales et secondaires, respectivement, l'objet de l'invention étant de résoudre le problème associé aux techniques antérieures qui ne permettent pas d'enregistrer les données d'images principales et secondaires, respectivement. Le procédé selon l'invention consiste : à coder numériquement et à compresser numériquement les images originales entrées à l'aide de l'unité de traitement d'images ; à séparer ou à répliquer les images originales qui ont été codées numériquement et compressées numériquement, ce qui permet de former le flux de données d'image principales et le flux de données d'image secondaires, à les enregistrer ensuite dans l'unité de traitement d'enregistrement. L'invention est utilisée pour le procédé d'enregistrement vidéo numérique dans un disque dur, une bande et un disque optique, lesquels présentent une importante capacité de stockage d'images numériques.
