Abstract
(EN)
The present invention pertains to an information processing device and an information processing method capable of handling reproduction of a Point Cloud having no time information. The present invention involves: generating meta data including reproduction information necessary for reproducing encoded data obtained by encoding one frame of a Point Cloud by V-PCC or G-PCC and reproduction feasibility information used for determining feasibility of reproduction of the encoded data; and storing the encoded data and the meta data in a file having a file structure utilizing a prescribed ISOBMFF technology. The present invention can be applied to, for example, a data generation device that generates a file for storing encoded data of a Point Cloud having no time information.

L’invention concerne un dispositif de traitement d'informations et un procédé de traitement d'informations permettant de gérer la reproduction d'un nuage de points sans informations temporelles. La présente invention consiste : à générer des métadonnées comprenant des informations de reproduction nécessaires pour reproduire des données codées obtenues par codage d'une trame d'un nuage de points par V-PCC ou G-PCC et des informations de faisabilité de reproduction utilisées pour déterminer la faisabilité de la reproduction des données codées ; et à mémoriser les données codées et les métadonnées dans un fichier ayant une structure de fichier utilisant une technologie ISOBMFF prescrite. La présente invention peut être appliquée, par exemple, à un dispositif de génération de données qui génère un fichier servant à mémoriser des données codées d'un nuage de points sans informations temporelles.
