Abstract
The invention relates to receiving, transmitting, and generating a manifest describing a plurality of versions of partitioned timed media data comprising timed samples that comprise subsamples. A portion of the data is transmitted as a media segment file comprising independently encapsulated components comprising partition components containing a subsample selected from among the plurality of subsamples of one of the timed samples and one corresponding subsample of the other timed samples and one reference component comprising at least one extractor identifying at least the partition component. The manifest comprises representations comprising at least a description of a version of a portion of the partitioned timed media data, one said representation comprising a description of components among which one component is required to reconstruct at least partially the partitioned timed media data and among which at least one component is an optional component that can be selected to reconstruct at least a portion of the partitioned timed media data.
