More Information
Summary:For an encrypted content (104) stored in a content accumulation medium (102), small-data-amount information on the encrypted content (104) is stored in the content accumulation medium (102) in correlation to the encrypted content (104). Thus, without decrypting the large-data-amount encrypted content (104), it is possible to judge the encrypted content (104) according to the small-data-amount information. This enables a user to easily judge a plurality of contents stored in the content accumulation medium. Pour un contenu codé (104) stocké dans un support d'accumulation de contenus (102), une information réduite sur le contenu codé (104) est stockée dans le support d'accumulation de contenus (102) en corrélation avec le contenu codé (104). Ainsi, sans décoder le contenu codé complet (104), on peut estimer le contenu codé (104) sur la base de l'information réduite. Ceci permet à l'utilisateur d'estimer facilement la pluralité de contenus stockés dans le support d'accumulation de contenus.
