Title (EN) MANAGING DATA FILE TRANSMISSION
(FR) GESTION DE TRANSMISSION DE FICHIERS DE DONNÉES
Abstract:
(EN) In a method for managing transmission of data files to users, a first file is divided into a plurality of first segments and a second file is divided into a plurality of second segments. A first segment is sent to a first user and a different first segment is sent to a second user. A second segment is sent to the first user and a different second segment is sent to the second user. At least part of a segment sent to the first user is combined with at least part of a segment sent to the second user to produce a combined segment which is of smaller size than the total size of the at least parts of segments before combining. The combined segment is transmitted to the first user and to the second user for each user to recover a segment using the combined segment and at least part of a segment.
(FR) La présente invention se rapporte à un procédé adapté pour gérer la transmission de fichiers de données à des utilisateurs. Dans le procédé selon l'invention, un premier fichier est divisé en une pluralité de premiers segments et un second fichier est divisé en une pluralité de seconds segments. Un premier segment est envoyé à un premier utilisateur et un premier segment différent est envoyé à un second utilisateur. Un second segment est envoyé au premier utilisateur et un second segment différent est envoyé au second utilisateur. Au moins une partie d'un segment envoyé au premier utilisateur est combinée avec au moins une partie d'un segment envoyé au second utilisateur. Ceci a pour but de produire un segment combiné dont la taille est réduite par rapport à la taille totale des parties des segments avant la combinaison. Le segment combiné est transmis au premier utilisateur et au second utilisateur, à charge pour chaque utilisateur de récupérer un segment au moyen du segment combiné et d'au moins une partie d'un segment.
