Abstract: front page image
(EN)Conventionally, it is known that device authentication is performed between a drive device and a reproduction device reproducing a content before reading the content from a recording medium. The device authentication testifies the validity of the reproduction device. After validity is testified, the reproduction device can read any of the contents stored in the recording medium. There is provided a read device to limit the type of contents acquired by the reproduction device by permitting the reproduction device to read contents satisfying a particular condition and inhibiting the reproduction device to read the other contents.
(FR)Conventionnellement, il est connu qu’une authentification de dispositif soit réalisée entre un dispositif lecteur et un dispositif de reproduction reproduisant un contenu, avant de lire le contenu d’un support d’enregistrement. L’authentification du dispositif atteste de la validité du dispositif de reproduction. Après que la validité est attestée, le dispositif de reproduction peut lire l’un des contenus quelconques stockés sur le support d’enregistrement. Est fourni un dispositif de lecture pour limiter le type de contenus acquis par le dispositif de reproduction en permettant au dispositif de reproduction de lire des contenus satisfaisant une condition particulière et en empêchant le dispositif de reproduction de lire les autres contenus.
(JA) 従来、記録媒体から、コンテンツを読み出す前に、ドライブ装置と、コンテンツを再生する再生装置の間で、機器認証を行うことが知られている。機器認証は、再生装置の正当性を証明するものであり、正当性が証明された後は、再生装置は、記録媒体に記憶されている何れのコンテンツも読み出すことができる。  本発明は、再生装置に、特定の条件を満たすコンテンツの読み出しを許可し、他のコンテンツの読み出しを禁止することで、再生装置の取得するコンテンツの種類を限定する読出装置を提供する。
