ABSTRACT:
A method for distributing video sequences according to a nominal flow format that describes a multiplicity of audiovisual scenes, each scene including a multiplicity of hierarchized audiovisual objects and a descriptor of the hierarchy and of spatial and temporal relationships among the objects, each video object including at least one complete I-VOP digital plane, including generating a first modified flow having the format of a nominal flow and a second flow of any format including digital information required for reconstruction of modified planes by analyzing the flow of video sequences, separately transmitting the two flows generated from a server to destination equipment, and calculating on the destination equipment a synthesis of a flow of the nominal format as a function of the first and second flows.
