Abstract
Receiving, transmitting, and generating streamed timed media data organized into temporal media segments, the timed media data belonging to partitioned timed media data comprising timed samples, each timed sample comprising a plurality of subsamples, the timed media data being transmitted as at least two media segment files, each comprising at least one independently encapsulated component. A manifest comprises a dependency item of information indicating a dependency relation between components and a dependency characterization item of information for interpreting the dependency item of information. Alternatively, the manifest comprises at least two different descriptions of at least one component, a first description comprising at least a first dependency item of information indicating a dependency relation from the at least one component to another component and a second description comprising at least a second dependency item of information indicating a dependency relation from another component to the at least one component.
