Title
(EN) PARTIAL FRAME REPLACEMENT ENABLING MULTIPLE VERSIONS IN AN INTEGRATED VIDEO PACKAGE
(FR) REMPLACEMENT DE TRAME PARTIELLE PERMETTANT DE MULTIPLES VERSIONS DANS UN CONTENEUR VIDÉO INTÉGRÉ
Abstract
(EN)
Multiple different versions of media content are contained in a single package of audio-video media content, using compression algorithms that reduce storage and bandwidth required for storing multiple full-resolution versions of the media. Portions of individual frames are replaced during playback so that only the pixels that differ between versions need to be stored.
(FR)
Selon la présente invention, de multiples versions différentes de contenu multimédia sont contenues dans un seul conteneur de contenu multimédia audio-vidéo, à l'aide d'algorithmes de compression qui réduisent le stockage et la largeur de bande requis pour stocker de multiples versions à pleine résolution du contenu multimédia. Des parties de trames individuelles sont remplacées pendant la lecture de telle sorte que seuls les pixels qui diffèrent entre des versions ont besoin d'être stockés.
