Title
(EN) DEVICE AND METHOD FOR FILTERING OUT HARMFUL VIDEO FILE
(FR) DISPOSITIF ET PROCÉDÉ D'ÉLIMINATION PAR FILTRAGE D'UN FICHIER VIDÉO NUISIBLE
(KO) 유해 동영상 파일을 필터링 하기 위한 장치 및 방법
Abstract
(EN) The present invention relates to a device and a method for controlling smart TV video time and filtering out a harmful video. The harmful video file filtering-out device according to an embodiment may comprise: a key frame extraction unit for extracting a key frame from a video file in which an open event has occurred; an image classification unit for calculating the degree of harmfulness by providing the extracted key frame to a classifier; and a content blocking unit for comparing the calculated degree of harmfulness with a harmfulness threshold value, and when the degree of harmfulness is equal to or greater than the harmfulness threshold value, determining the video file as a harmful video file so as to process to block the determined harmful video file.
(FR) La présente invention concerne un dispositif et un procédé de commande de temps vidéo d'un téléviseur intelligent et d'élimination par filtrage d'une vidéo nuisible. Le dispositif d'élimination par filtrage d'un fichier vidéo nuisible selon un mode de réalisation peut comprendre : une unité d'extraction d'image clé pour extraire une image clé d'un fichier vidéo dans lequel un événement d'ouverture est survenu ; une unité de classification d'image pour calculer le degré de nocivité par fourniture de l'image clé extraite à un classifieur ; et une unité de blocage de contenu pour comparer le degré de nocivité calculé à une valeur seuil de nocivité, et quand le degré de nocivité est égal ou supérieur à la valeur seuil de nocivité, déterminer que le fichier vidéo est un fichier vidéo nuisible de façon à procéder au blocage du fichier vidéo nuisible déterminé.
