Abstract
(EN)
The invention relates to a method and device for encapsulating media data into a media file and parsing a media file. The method comprising according to one of its aspects:including, in the media file, a first track comprising media samples, each media sample contains a set of one or more NAL units; including, in the media file, a second track comprising an extractor, the extractor is a structure referencing a data entity in a media sample contained in the first track; and including, in the extractor, a copy mode attribute that identifies, in the media sample, the referenced data entity relatively to one or more NAL units contained in the media sample.
(FR)
L'invention concerne un procédé et un dispositif pour encapsuler des données multimédias dans un fichier multimédia et analyser un fichier multimédia. Le procédé consiste, selon un de ses aspects, à : inclure, dans le fichier multimédia, une première piste comprenant des échantillons multimédias, chaque échantillon multimédia contenant un ensemble d'une ou plusieurs unités NAL ; inclure, dans le fichier multimédia, une seconde piste comprenant un extracteur, l'extracteur étant une structure faisant référence à une entité de données dans un échantillon multimédia contenu dans la première piste ; et inclure, dans l'extracteur, un attribut de mode de copie qui identifie, dans l'échantillon multimédia, l'entité de données référencée par rapport à une ou plusieurs unités NAL contenues dans l'échantillon multimédia.
