Abstract

Procédé de restitution, sur un terminal d’un spectateur, d’un lieu regroupant plusieurs espaces distincts dans lequel un spectateur se déplace virtuellement L’invention se rapporte à un procédé de restitution, sur un terminal (108) d'un spectateur (SP1), d'un lieu (100) dans lequel le spectateur (SP1) se déplace virtuellement, le lieu (100) regroupant plusieurs espaces distincts, les espaces étant filmés par des caméras respectives (101, 102, 103, 104), ledit procédé étant caractérisé en ce qu'il comprend les phases suivantes : une phase d'obtention de la description de différentes qualités de flux audiovisuels filmés dans les différents espaces ; une phase de récupération de la position virtuelle du spectateur (SP1) ;une phase de sélection des flux reçus de manière à ce que pour un espace donné, à un moment donné, l'entité de gestion (200) demande à recevoir un seul flux audiovisuel de format variable parmi les flux audiovisuels disponibles ; et,une phase de demande de restitution du lieu (100) sur le terminal (108) du spectateur (SP1), en utilisant les flux audiovisuels sélectionnés. Figure 1Method for rendering, on a spectator's terminal, a place bringing together several distinct spaces in which a spectator moves virtually. The invention relates to a method for rendering, on a terminal (108) of a spectator (SP1 ), of a place (100) in which the spectator (SP1) moves virtually, the place (100) bringing together several distinct spaces, the spaces being filmed by respective cameras (101, 102, 103, 104), said method being characterized in that it comprises the following phases: a phase for obtaining the description of different qualities of audiovisual streams filmed in the different spaces; a phase for recovering the virtual position of the spectator (SP1); a phase for selecting the streams received so that for a given space, at a given time, the management entity (200) requests to receive a single stream audiovisual of variable format among the available audiovisual streams; and, a phase of requesting restitution of the location (100) on the terminal (108) of the viewer (SP1), using the selected audiovisual streams.
