Abstract
(EN)
Systems, methods, and devices of the various aspects enable uplink delivery and downlink distribution of media content to users in live uplink streaming services. In various embodiments, media in a live uplink streaming service may be distributed by unicast and/or broadcast delivery methods. Various embodiments may include receiving, in a processor of a live uplink streaming sink computing device, assistance data for a live streaming session, selecting, by the processor, one or more delivery methods for processed media of the live streaming session based at least in part on the assistance data, and transmitting, by the processor, the processed media using the selected delivery methods.

Divers aspects de l'invention concernent des systèmes, des procédés et des dispositifs permettant une distribution en liaison montante et une distribution en liaison descendante d'un contenu multimédia à des utilisateurs dans des services de diffusion en continu en liaison montante en direct. Selon divers modes de réalisation, un contenu multimédia dans un service de diffusion en continu en liaison montante en direct peut être distribué par l'intermédiaire de procédés de monodiffusion et/ou de diffusion générale. Divers modes de réalisation peuvent comprendre la réception, dans un processeur d'un dispositif informatique de collecteur de diffusion en continu en liaison montante en direct, de données d'assistance pour une session de diffusion en continu en direct, la sélection, par le processeur, d'un ou plusieurs procédés de distribution pour un contenu multimédia traité de la session de diffusion en continu en direct en fonction, au moins en partie, des données d'assistance, et la transmission, par le processeur, du contenu multimédia traité à l'aide des procédés de distribution sélectionnés.
