Abstract

La presente invención se refiere a un método de codificación de imágenes en movimiento que incluye: codificar, utilizando un vector de movimiento, un bloque actual que es codificado; generar una pluralidad de vectores de movimiento predictivos (S11, S12); y codificar el vector de movimiento utilizando uno de los vectores de movimiento predictivos (S13) y cuando un bloque co-localizado que es incluido en una imagen codificada y co-localizado con el bloque actual tiene dos vectores de movimiento de referencia y las direcciones de referencia de los dos vectores de movimiento de referencia son las mismas (S11), un primer vector de predicción se genera utilizando un primer vector de movimiento de referencia y un segundo vector de predicción se genera utilizando un segundo vector de movimiento de referencia en la generación de una pluralidad de vectores de movimiento predictivos (S12).
