Abstract
The invention relates to a data signal for animation of a graphic scene to be used by means for constructing images that can be displayed on at least one screen, a signal in which the scene is described in the form of a set of animation objects, each of which is associated with at least one characterization field defining a parameter of the object, comprising at least one quantization object, for which the characterization fields define the quantization rules for the characterization fields of the animation objects, each applicable to at least two distinct characterization fields, such that most or all of the characterization fields of the animation objects with a numeric value can be quantized. The invention also relates to the corresponding process and device.
