(EN) AN APPARATUS, A METHOD AND A COMPUTER PROGRAM FOR VIDEO CODING AND DECODING
(FR) APPAREIL, PROCÉDÉ ET PROGRAMME INFORMATIQUE DE CODAGE ET DE DÉCODAGE VIDÉO
Abstract
(EN)
A method comprising: encoding an input picture sequence into at least a first bitstream and a second bitstream, said encoding comprising; encoding, into the first and the second bitstream, a set of shared coded pictures per a time instance comprising a complete representation of a content for the time instance; encoding, into the first and the second bitstream, other pictures as intermediate pictures, the intermediate pictures having a width and height equal to the width and height of a shared coded picture and corresponding to a time instance of the content, wherein the intermediate pictures of first bitstream represent a first aspect of the content and the intermediate pictures of second bitstream represent a second different aspect of the content.
(FR)
L’invention concerne un procédé consistant à coder une séquence d'images d'entrée en au moins un premier flux binaire et un second flux binaire, ledit codage consistant à : coder, dans le premier et le second flux binaire, un ensemble d'images codées partagées par instance temporelle comprenant une représentation complète d'un contenu pour l'instance temporelle ; et coder, dans le premier et le second flux binaire, d'autres images en tant qu'images intermédiaires, les images intermédiaires ayant une largeur et une hauteur égales à la largeur et à la hauteur d'une image codée partagée et correspondant à une instance temporelle du contenu, les images intermédiaires du premier flux binaire représentant un premier aspect du contenu et les images intermédiaires du second flux binaire représentant un second aspect différent du contenu.
