Patent

CA 2192080

Parental information of a video program recorded on an optical disk is always checked in a disk player. Even if a jump of laser beam tracing of an optical head erroneously occurs due to shocks or vibrations, the content of parental information assigned to the destination of optical head jumping is checked, to thereby achieve an accurate parental control of selective restriction for the video whose reproduction or presentation is restricted by the parental information.

On décrit un support d'enregistrement d'informations et un système de communication d'informations qui permettent à des parents de gérer/évaluer l'opportunité d'une reproduction ou d'une réception. Les parents peuvent contrôler si les informations de certaines images doivent faire l'objet de restrictions, au niveau des séquences par exemple. Même si survient un saut involontaire en matière de reproduction, les parents peuvent effectuer un contrôle au point où cette reproduction reprend, ce qui leur permet une vérification efficace.
