Abstract
Se proporciona un codificador (100) el cual incluye circuitaje (160) y memoria (162). Usando la memoria (162), el circuitaje (160) genera una lista la cual incluye candidatos para un primer vector de movimiento para una primera división. La lista tiene un tamaño de lista máximo y un orden de los candidatos, y por lo uno del tamaño de lista máximo o el orden de los candidatos depende de por lo menos uno de un tamaño de división o una forma de división de la primera división. El circuitaje (160) selecciona el primer vector de movimiento de entre los candidatos incluidos en la lista; codifica un índice indicando el primer vector de movimiento de entre los candidatos en la lista dentro de la corriente de bits con base en el tamaño de lista máximo; y genera la imagen predicha para la primera división usando el primer vector de movimiento.
