Method and apparatus for encapsulating and parsing a media file having split samples

Abstract

Encapsulating media data into a media file, the media data comprising base data and additional data to the base data, the method comprising, generating a track comprising a sequence of samples, each sample being associated with a single time. Each sample comprises a first part including data of the base data associated with the single time and at least one additional part including data of the additional data associated with the single time. Descriptive metadata including information relative to the organization of the at least one additional part of the samples in the track is generated. The media file comprising the generated track and descriptive metadata is then generated. The descriptive metadata may comprise decoder configuration for the first part of the samples only and for an aggregation of the first part and at least one additional part of the samples. The generated media file may include sample auxiliary information associated with the base data and / or with the additional data. Parsing the encapsulated media is also disclosed. Fig.3
