(EN) ARRANGEMENT FOR INDEPENDENTLY REQUESTING A PLAYING AUTHORIZATION FOR A REPRODUCED ENCRYPTED INFORMATION SIGNAL
(FR) AGENCEMENT PERMETTANT DE DEMANDER INDEPENDAMMENT UNE AUTORISATION DE LECTURE POUR UN SIGNAL D'INFORMATION CRYPTE REPRODUIT
Abrégé
(EN)
An arrangement (1) for verifying a playing authorization for an encrypted information signal (I) reproduced by means of a reproducing device (2, 3) and for supplying a decrypted information signal (I) when a playing authorization is available, comprises verification means (19) for verifying a playing authorization for a reproduced encrypted information signal (I), and comprises decryption means (32) fro decrypting a reproduced encrypted information signal (I) when a playing authorization is available, and comprises interrogation means (43, 35) for independently requesting a playing authorization, which interrogation means include communication means (43) which, in the absence of a playing authorization for a reproduced encrypted information signal (I) are capable of setting up a data link (49, 52, 56, 59) and of supplying playing authorization request information to a playing authorization allocation device (51, 53, 57, 60) via the data link (49, 52, 56, 59) and of receiving a playing authorization for the reproduced encrypted information signal (I) from the playing authorization allocation device (51, 53, 57, 60).

Agencement (1) permettant de vérifier une autorisation de lecture pour un signal d'information (I) crypté reproduit à l'aide d'un dispositif de reproduction (2, 3) et de fournir un signal d'information (I) décrypté lorsque l'autorisation de lecture existe. Ledit agencement comporte un moyen de vérification (19) destiné à vérifier une autorisation de lecture pour un signal d'information (I) crypté reproduit, un moyen de décryptage (32) destiné à décrypter un signal d'information (I) crypté reproduit lorsque l'autorisation de lecture existe, et un moyen d'interrogation (43, 35) permettant de demander indépendamment une autorisation de lecture. Ledit moyen d'interrogation comporte un moyen de communication (43) qui, en l'absence d'une autorisation de lecture pour un signal d'information (I) crypté reproduit, est capable d'établir une liaison (49, 52, 56, 59) de données et de fournir l'information de demande d'autorisation de lecture à un dispositif d'attribution (51, 53, 57, 60) d'autorisation de lecture par l'intermédiaire de la liaison (49, 52, 56, 59) de données et de recevoir une autorisation de lecture pour le signal d'information (I) crypté reproduit, émanant du dispositif d'attribution (51, 53, 57, 60) d'autorisation de lecture.
