Abstract: The representation of content, in a scene representation, is enriched with a view to the adaptive use of the latter according to a set of common parameters. A sub-graph of the scene graph, which is susceptible to variable processing, is identified. For this purpose, two new types of scene element can be defined, one of which allows the identification of the sub-graph and the second enables application of the set of common parameters in relation to the sub-graph. An example of the first type is a node of so-called “AdaptivityControl” type which encompasses the entire sub-graph, a list of the nodes describing the set of common parameters and a group of fields for dynamic updating of the content of this node. An example of the second type is a node of so-called “CompressedImageStrategy” type which comprises information relating to the object to be coded and the coding parameters.

Abstract: The disclosed method for coding data includes the exchange between the transmitter and the receiver, in the course of the session, of attributes of collaboration messages that are able to be used in said session and of indices associated with these attributes. In various implementations, the attributes and their indices may be used by these pieces of equipment for updating a shared dictionary of indexed attributes. Upon coding, the attributes of the collaboration messages may be substituted with their indices; and upon decoding, the inverse operation may be carried out. The shared dictionaries may be destroyed at the end of the session.
