Title (EN) PROCESSING OMNIDIRECTIONAL MEDIA WITH DYNAMIC REGION-WISE PACKING
(FR) TRAITEMENT DE SUPPORTS OMNIDIRECTIONNELS AVEC MISE EN PAQUET DYNAMIQUE PAR RÉGION
Abstract:
(EN) An example device for processing video data includes a memory configured to store an omnidirectional video stream, and a processor implemented in circuitry and configured to process (e.g., encode, transmit, receive, or decode) a first frame of a set of file format samples of the omnidirectional video stream, the set of file format samples referring to a sample entry, the first frame having a first region-wise packing scheme, and process a second frame of the set of file format samples referring to the sample entry, the second frame having a second region-wise packing scheme different than the first region-wise packing scheme. In this manner, a single omnidirectional video bitstream may include an entire virtual reality (VR) video content with most-requested regions being optimized with a largest number of color samples per unit of area.
(FR) Un exemple de l'invention concerne un dispositif pour traiter des données vidéo, comprenant une mémoire configurée pour stocker un flux vidéo omnidirectionnel et un processeur mis en œuvre dans des circuits et configuré pour traiter (par exemple coder, émettre, recevoir ou décoder) une première trame d'un ensemble d'échantillons de format de fichier du flux vidéo omnidirectionnel, l'ensemble d'échantillons de format de fichier se référant à une entrée d'échantillon et la première trame possédant un premier schéma de mise en paquet par région, et traiter une deuxième trame de l'ensemble d'échantillons de format de fichier en référence à l'entrée d'échantillon, la deuxième trame possédant un deuxième schéma de mise en paquet par région différent du premier schéma de mise en paquet par région. De cette manière, un train de bits vidéo omnidirectionnel unique peut comprendre un contenu vidéo en réalité virtuelle (VR) entier dont les régions les plus demandées sont optimisées avec un plus grand nombre d'échantillons de couleur par unité de surface.
