Title (EN) PROVIDING TILE VIDEO STREAMS TO A CLIENT
(FR) FOURNITURE DE FLUX VIDÉO TUILÉS À UN CLIENT
Abstract:
(EN) A method is described for providing one or more tile streams to a client device for rendering a region-of-interest (ROI), wherein said ROI defines a region of a tile representation of a source video and wherein said method comprises: rendering a region-of-interest (ROI) video stream comprising a ROI of said source video; receiving ROI position information of at least one frame of said ROI video stream; and, receiving one or more tile streams that are requested the basis of said ROI position information and a spatial manifest file, said spatial manifest file defining one or more tile representations of said source video, a tile representation comprising one or more tile identifiers for identifying one or more tile streams and a tile position information defining the spatial position of said tile streams.
(FR) L'invention concerne un procédé de fourniture d'un ou plusieurs flux vidéo tuilés à un dispositif client pour le rendu d'une zone d'intérêt (ROI), ladite ROI définissant une zone d'une représentation tuilée d'une vidéo source. Le procédé selon l'invention consiste : à rendre un flux vidéo de zone d'intérêt (ROI) comprenant une ROI de ladite vidéo source; à recevoir des informations de position de ROI d'au moins une trame dudit flux vidéo ROI; et à recevoir un ou plusieurs flux tuilés requis d'après lesdites informations de position de ROI et un fichier manifeste spatial, ledit fichier manifeste spatial définissant une ou plusieurs représentations tuilées de ladite vidéo source, une représentation tuilée comprenant un ou plusieurs identifiants de tuile pour identifier un ou plusieurs flux tuilés et des informations de position de tuile définissant la position spatiale dudit flux tuilé.
