Abstract: front page image
(EN)When a content is reproduced, a history expressing whether the reproduced matter has been already viewed by a user is stored. On the basis of the stored history, a viewing degree which expresses the ratio of important scene sections viewed by the user to all the important scene sections in each content is calculated. Then, contents of higher viewing ratios computed from among a plurality of contents are chosen as candidates for contents which have to be deleted or compressed.
(FR)Selon l'invention, lorsqu'un contenu est reproduit, un historique exprimant si le sujet reproduit a déjà été visualisé par un utilisateur est stocké. Sur la base de l'historique stocké, un degré de visualisation qui exprime le rapport des sections de scène importantes visualisées par l'utilisateur sur toutes les sections de scène importantes dans chaque contenu est calculé. Les contenus ayant de plus hauts rapports de visualisation calculés parmi une pluralité de contenus sont ensuite choisis comme candidats pour des contenus qui doivent être supprimés ou compressés.
(JA) コンテンツの再生時に、その再生内容がユーザにより視聴されたかどうかを示す履歴を記憶する。 記憶した履歴に基づいて、コンテンツ毎に、その全重要シーン区間において、ユーザにより視聴された割合を示す視聴度を算出する。 そして、複数のコンテンツの中から算出された視聴度の大きいコンテンツを削除または圧縮すべきコンテンツの候補として選び出す。
