Title (EN) METHOD AND APPARATUS FOR MULTIPLEXING AND DISTRIBUTING DATA WITH PREFORMATTED REAL-TIME VIDEO
(FR) PROCEDE ET DISPOSITIF POUR MULTIPLEXER ET DISTRIBUER DES DONNEES AVEC VIDEO EN TEMPS REEL PREFORMATEE
Abstract:
(EN) A system for providing efficient constant bit rate distribution of variable bit-rate encoded video programs while facilitating the distribution of encoded video programs, along with Auxiliary Data of a general character, to one or more receivers. At a particular receiver, a customized augmented video program is created by inserting selected portions of the Auxiliary Data into a selected encoded video program. The encoded video portion of the augmented video program can be transmitted, decoded and displayed in real time, while the Auxiliary Data need not be transmitted in real time but can be stored locally at the receiver for real-time presentation at a later time. Real-time presentation might include insertion into the video program while non-real-time presentation might include insertion into non-video applications separate from the video program.
(FR) Système permettant de distribuer efficacement en débit binaire constant des programmes vidéo codés en débit binaire variable, tout en facilitant la distribution des programmes vidéo codés, accompagnés de Données Auxiliaires de caractère général, à un ou plusieurs récepteurs. Au niveau d'un récepteur particulier, on crée un programme vidéo augmenté personnalisé en insérant des parties sélectionnées des Données Auxiliaires dans un programme vidéo codé sélectionné. La partie vidéo codée du programme vidéo augmenté peut être transmise, décodée et affichée en temps réel, tandis que les Données Auxiliaires n'ont pas besoin d'être transmises en temps réel, mais peuvent être stockées localement au niveau du récepteur en vue d'une présentation en temps réel ultérieure. La présentation en temps réel peut comporter une insertion dans le programme vidéo, tandis que la présentation non en temps réel peut comporter une insertion séparée dans des applications non vidéo et dans le programme vidéo.
