A method of processing a tree data structure organized into interconnected elements. The method comprises the steps of: defining processing units as subsets of interconnected elements and allocating each processing unit a processing time on which the data of the allocated processing unit is to be used by a unit that is the destination for the data. The processing method can be applied to streaming metadata, in particular for adaptation of scalable multimedia content.

Method for processing a data tree structure

A method for the transmission of data flows; data flows, server, terminal, method for reception and use corresponding thereto. The invention relates to a method for the transmission of at least one flow of data towards at least one terminal, said flow or flows being organized in the form of flow units, characterised in that at least some of said flow units comprise at least one pointer pointing towards at least one flow unit of said flow or another flow in order to optimize processing in the terminal and/or the useful flow rate of said flow(s).

Dependent data stream transmission procedure

The invention regards a method for broadcasting multimedia signals towards a plurality of terminals as a data flow comprising successive packets, being organised into sessions, a session comprising a set of packets forming a whole, at least some of said sessions being transmitted under several versions, corresponding to different starting moments. According to the invention, such a method implements a mechanism for merging versions of a same session, so that at least two versions starting at different moments use, at first, session portions which are peculiar to them, and, subsequently, a shared session portion.
