Title (EN) TRANSMISSION OF VIDEO CONTENT BASED ON FEEDBACK
(FR) TRANSMISSION DE CONTENU VIDÉO SUR LA BASE D'UNE RÉTROACTION
Abstract:
(EN) Methods and systems are disclosed relating to adaptive transmission of video content based on feedback, for example feedback from one or more user equipment receiving the video content using an over-the-air broadcast. One operation may comprise receiving from a plurality of remote user equipment (UE) information relating to respective viewports relative to video content. Another operation may comprise determining data representing an aggregate viewport based on the viewport information from the plurality of UEs. Another operation may comprise transmitting video content data to the plurality of UEs based on the determined aggregate viewport.
(FR) L'invention concerne des procédés et des systèmes relatifs à la transmission adaptative d'un contenu vidéo sur la base d'une rétroaction, par exemple une rétroaction provenant d'un ou de plusieurs équipements utilisateur recevant le contenu vidéo à l'aide d'une diffusion hertzienne. Une opération peut consister à recevoir, à partir d'une pluralité d'équipements utilisateur (UE) distants, des informations relatives à des fenêtres d'affichage respectives par rapport à un contenu vidéo. Une autre opération peut consister à déterminer des données représentant une fenêtre d'affichage d'agrégat sur la base des informations de fenêtre d'affichage à partir de la pluralité d'UE. Une autre opération peut consister à transmettre des données de contenu vidéo à la pluralité d'UE sur la base de la fenêtre d'affichage d'agrégat déterminée.
