(57) Abstract:
(EN): A content recording device (401) is provided with an acquisition unit (411) for acquiring content that has a variable-length packet structure, an encryption unit (412) for encrypting the acquired content and thereby generating encrypted data, and a recording unit (413) for recording the generated encrypted data in a recording medium in fixed-length block units. The encrypted data includes an invalidated area that is not needed for content reproduction, and the recording unit (413) records the size of the invalidated area in the recording medium.
(FR): L'invention concerne un dispositif d'enregistrement de contenu (401) comprenant : une unité d'acquisition (411) permettant d'acquérir un contenu qui possède une structure de paquet de longueur variable ; une unité de chiffrement (412) permettant de chiffrer le contenu acquis et de générer ainsi des données chiffrées ; et une unité d'enregistrement (413) permettant d'enregistrer les données chiffrées générées dans un support d'enregistrement dans des unités de bloc de longueur fixe. Les données chiffrées comprennent une zone invalidée qui n'est pas requise pour la reproduction de contenu, et l'unité d'enregistrement (413) enregistre la taille de la zone invalidée dans le support d'enregistrement.
(JA): コンテンツ記録装置(401)は、可変長パケット構造を有するコンテンツを取得する取得部(411)と、取得されたコンテンツを暗号化することにより暗号化データを生成する暗号化部(412)と、生成された暗号化データを固定長のブロック単位で記録媒体に記録する記録部(413)とを備える。暗号化データには、コンテンツの再生に不要な無効化領域が含まれ、記録部(413)は、無効化領域のサイズを記録媒体に記録する。
