Abstract
L'invention autorise diverses formes de réalisation qui permettent d'obtenir une vitesse accrue et des temps de traitement informatique réduits concernant la lecture et l'exploration d'un contenu multimédia, grâce à l'utilisation de deux types d'objets de données servant à présenter ledit contenu multimédia. Le premier type d'objet de données comprend des données de contenu multimédia rendu destinées à une antémémoire rendue, ou des instructions de rendu destinées à une antémémoire de chaîne de peinture ou à une antémémoire de présentation. L'antémémoire de chaîne de peinture et l'antémémoire de présentation peuvent tirer parti de capacités de traitement client accrues. Le second type d'objet de données comprend un contenu sémantique correspondant au contenu multimédia rendu. Le support de stockage contenant ces deux types d'objets de données est appelé antémémoire rendue. Le contenu sémantique peut inclure des emplacements, des tailles, des formes, et des identificateurs de ressources uniformes cibles d'hyperliens, de synchronisation d'éléments multimédia, et d'autres instructions de lecture de contenu. La lecture très rapide du contenu stocké dans l'antémémoire rendue est due à l'élimination des étapes d'organisation du contenu et de génération de la représentation sémantique du contenu. Cette démarche est exigée chaque fois que le contenu est lu après extraction d'une antémémoire classique. Les seules conditions requises pour mettre en oeuvre un contenu à partir de l'antémémoire rendue consistent à lire le contenu rendu, à lire le contenu sémantique, à restaurer la représentation sémantique, et à lire le contenu. Le mécanisme de mise en antémémoire prévu dans diverses formes de réalisation de l'invention est indépendant du format de fichier du contenu et du format du contenu sémantique stocké.
