FIELD: information technology.
SUBSTANCE: method of organising streamed data involves storing streamed data in a file, identifying metadata applicable to a subset of the streamed data, and forming at least one group of one or more samples of the streamed data, each sample in a group having identical metadata content for a metadata type. The file may be in accordance with ISO base media file format. Storing streamed data in a file may include storing in a reception hint track. At least one group may be indicated in a sample group description box. The metadata type may be indicated by a grouping type and grouping instance data, the grouping type specifying semantics of the grouping instance data and the metadata content. The metadata content may contain a metadata payload and zero or more metadata payload extensions, where the metadata payload is included in a first structure and the zero or more metadata payload extensions are included in a second structure.
EFFECT: easier access to the desired sections or segments of streamed data.
