Abstract
(EN)
Disclosed is a content management server that allows the reproduction of content to be restarted from an appropriate reproduction interrupt position even in cases where a piece of content copied to a content reproduction device has been edited. In the disclosed content management server (200) which manages pieces of content and which edits content by deleting a portion of the content or by adding a portion to the content: the transmit/receive section (202) receives a first reproduction interrupt position which is the position at which the reproduction of content was interrupted in a content reproduction device (100); the reproduction-interrupt-position calculating section (209) calculates a second reproduction interrupt position on the basis of said first reproduction interrupt position and an edit segment within the content and to be deleted by editing, said second reproduction interrupt position corresponding to the position in the content after editing at which the reproduction of the content was interrupted in the content reproduction device (100); and the transmit/receive section (202) transmits the second reproduction interrupt position to the content reproduction device (100).

L'invention porte sur un serveur de gestion de contenu qui permet de redémarrer la reproduction d'un contenu à partir d'une position d'interruption de reproduction appropriée même dans le cas où un élément de contenu copié dans un dispositif de reproduction de contenu a été édité. Dans le serveur de gestion de contenu (200) décrit qui gère des éléments de contenu et qui édite du contenu par suppression d'une partie du contenu ou par ajout d'une partie au contenu : la section d'envoi/réception (202) reçoit une première position d'interruption de reproduction qui est la position au niveau de laquelle la reproduction de contenu a été interrompue dans un dispositif de reproduction de contenu (100) ; la section de calcul de position d'interruption de reproduction (209) calcule une seconde position d'interruption de reproduction sur la base de ladite première position d'interruption de reproduction et d'un segment d'édition contenu dans le contenu et devant être supprimé par édition, ladite seconde position d'interruption de reproduction correspondant à la position dans le contenu après édition, au niveau de laquelle la reproduction du contenu a été interrompue dans le dispositif de reproduction de contenu (100) ; et la section d'envoi/réception (200) envoie la seconde position d'interruption de reproduction au dispositif de reproduction de contenu (100).

 コンテンツ再生装置にコピーしたコンテンツに編集処理が施された場合でも適切な再生中断位置からの再生再開を可能とすることができるコンテンツ管理サーバ。コンテンツを管理するとともに、コンテンツ内の一部を削除又はコンテンツ内の一部へ追加することによりコンテンツの編集を行うコンテンツ管理サーバ(200)において、送受信部(202)は、コンテンツ再生装置(100)でコンテンツの再生が中断された位置である第1の再生中断位置を受信し、再生中断位置算出部(209)は、コンテンツ内の、編集により削除される編集区間、及び、第1の再生中断位置に基づいて、編集の後のコンテンツにおける、コンテンツ再生装置(100)でコンテンツの再生が中断された位置に対応する第2の再生中断位置を算出し、送受信部(202)は、第2の再生中断位置をコンテンツ再生装置(100)に送信する。
