Abstract
The present invention relates to a method of decoding audio-visual data allowing to process, on the basis of an improved syntactic language, distinct elements of a scene as objects for which individual animations, particular interactions user/elements, and specific relations between the elements and the defined animations and/or interactions can be provided, the description being organized in a hierarchical tree also including transversal connections provided both for embedding bidimensional and/or tridimensional objects in each other and optionally controlling the rendering of scenes from various view points, while maintaining a control of all related actions both in the embedded objects and/or scenes and in the original ones.
