Abstract

L'appareil d'enregistrement/de reproduction d'informations selon l'invention est réglé, par exemple, comme enregistreur sur disque dur/DVD, etc., et tout contenu entré de l'extérieur est enregistré dans une unité d'enregistrement, comme un disque dur ou un disque optique. Conformément à l'instruction de début d'enregistrement vidéo et à l'instruction de fin d'enregistrement vidéo, le contenu de programmes TV, etc. est enregistré dans une unité de stockage pendant la période entre l'heure de début d'enregistrement vidéo et l'heure de fin d'enregistrement vidéo. En outre, conformément aux informations EPG, etc., on obtient les informations de programme relatives au contenu. L'heure d'horloge de départ de l'enregistrement vidéo, l'heure d'horloge de fin de l'enregistrement vidéo et les informations relatives aux programmes sont enregistrées en association avec le contenu dans l'unité de stockage. En ce qui concerne le contenu enregistré dans l'unité de stockage, lorsque des instructions de division contenant la désignation d'un point de division provenant de l'utilisateur sont entrées, le contenu est divisé au point de division pour ainsi produire un contenu divisé. De plus, conformément aux informations de programme, les informations de programme correspondant à chacun des contenus divisés sont déterminées et, en association avec chacun des contenus divisés, sont enregistrées dans l'unité de stockage.
