Abstract

La invención se refiere a una señal de datos de animación de una escena gráfica, destinada a medios de construcción de imágenes que pueden presentarse en al menos una pantalla, habiendo sido dicha escena gráfica a animar probablemente cargada en dicho medios de construcción de imágenes, en forma de un conjunto de objetos, teniendo al menos algunos de estos objetos un identificador que les es propio, comprendiendo dicha señal: una máscara de animación única, entregada en preámbulo a dicha animación, y que asigna a al menos uno de dichos objetos una máscara elemental que comprende: la identificación de dicho objeto, tal como se define en dicha escena gráfica a animar, y la designación de la menos un campo de caracterización dinámica de dicho objeto, representativo de una característica de dicho objeto susceptible de ser modificado, tramas de animación que comprenden, según el orden definido por dicha máscara, datos de puesta al día de los campos de caracterización dinámicos de dichos objetos,para permitir su modificación, descodificando dicho medios de construcción los datos de dicha máscara de animación, e inicialización la animación a partir de ésta, y poniendo al día dicha escena en función de dichas tramas de animación.
