Title (EN) SECURELY INGESTING ENCRYPTED CONTENT INTO CONTENT SERVERS
(FR) IMPORTATION SECURISEE DE CONTENU CHIFFRE DANS DES SERVEURS DE CONTENU
Abstract: front page image
(EN)A system and method are directed towards including buffer packets into an unencrypted content stream at a same location as encryption related information such as an ECM, an EMM message, or the like, would be in a corresponding encrypted content stream. The buffer packets may comprise virtually any information, including a null packet, an ECM message. By inserting buffer packets in the same location, an overall file size, and frame locationing may be made to match the file size, and frame locationing of the encrypted content stream. The modified unencrypted content stream may be employed to generate trick play files, such as a fast forward file, fast reverse file, and so forth, as well as a corresponding index file that indicates locations of relevant content frames in the unencrypted content stream and the trick play files.
(FR)L'invention concerne un système et un procédé visant à inclure des paquets tampons dans un flux de contenu non chiffré, au même emplacement qu'occuperaient des données de chiffrement telles qu'un message ECM, un message EMM ou analogue dans un flux de contenu chiffré correspondant. Les paquets tampons comprennent pratiquement n'importe quelles données, y compris un paquet nul, un message ECM. L'insertion de paquets tampons à cet emplacement permet d'assurer que la taille globale du fichier et la localisation de trame correspondent à la taille du fichier, et de localiser les trames du flux de contenu chiffré. Le flux de contenu non chiffré modifié peut servir à produire des fichiers 'trick play' tels que, entre autres, un fichier d'avance rapide et un fichier de retour rapide, ainsi qu'un fichier d'index correspondant qui indique l'emplacement de trames de contenu pertinentes dans le flux de contenu non chiffré et les fichiers 'trick play'.
