Abstract

Se propone un método para inter predicción de un valor de muestra de un pixel actual de una pluralidad de pixeles de un bloque actual de un cuadro actual de una señal de video; el método (800) comprende: determinar (801) una pluralidad de vectores de movimiento a nivel de bloque relacionados uno-a-uno con una pluralidad de bloques del cuadro actual; determinar (803) un vector de movimiento a nivel de pixel del pixel actual con base en la pluralidad de vectores de movimiento a nivel de bloque; determinar uno o más pixeles de referencia en el cuadro de referencia basado en el vector de movimiento a nivel de pixel del pixel actual; y determinar (805) un valor de muestra del pixel actual inter-predicho basado en uno o más valores de muestra de uno o más pixeles de referencia en el cuadro de referencia; de esta manera se mejora la eficiencia de la codificación.
