Title (EN) METHOD AND APPARATUS FOR POINT-CLOUD STREAMING
(FR) PROCÉDÉ ET APPAREIL DE DIFFUSION EN CONTINU DE NUAGE DE POINTS
Abstract:
(EN) Systems and methods for identifying three dimensional (3D) content to stream. A method includes receiving information indicating a view field of a client device and identifying an amount of bandwidth available to stream the 3D content to the client device. The method includes assigning, for one or more of the objects, the bandwidth by, for each of the objects: determining whether the each object is within the view field of the client device based on a position of the each object; assigning a greater amount of the bandwidth to objects at least partially within the view field. The method includes streaming the 3D content to the client device according to the assigned bandwidth.
(FR) L'invention concerne des systèmes et des procédés pour identifier un contenu tridimensionnel (3D) à diffuser en continu. Un procédé consiste à recevoir des informations indiquant un champ de vision d'un dispositif client et à identifier une quantité de bande passante disponible pour diffuser en continu le contenu 3D au dispositif client. Le procédé consiste à attribuer, pour un ou plusieurs des objets, la bande passante par, pour chacun des objets : détermination du fait que chaque objet se trouve dans le champ de vision du dispositif client sur la base d'une position de chaque objet ; attribution d'une plus grande quantité de la bande passante à des objets au moins partiellement à l'intérieur du champ de vision. Le procédé consiste à diffuser en continu le contenu 3D au dispositif client selon la largeur de bande attribuée.
