Abstract

Se proporciona un codificador (100) que incluye: circuitería; y una memoria acoplada a la circuitería, en el cual en operación, la circuitería: genera una imagen de predicción de un bloque actual a ser procesado, por medio del uso de un primer vector de movimiento (paso S3001); y actualiza una tabla de predictores de vectores de movimiento basados en la historia (HMVP) por medio del uso de un primer candidato que tiene el primer vector de movimiento, la tabla de HMVP almacena, en un método de primera entrada-primera salida (FIFO), una pluralidad de segundos candidatos cada uno que tiene un segundo vector de movimiento usado para un bloque procesado (paso S3002), y en la actualización de la tabla de HMVP, la circuitería: determina si un tamaño del bloque actual es menor que o igual a un tamaño umbral (paso S30021); y omite la actualización de la tabla de HMVP (paso S30022) cuando se determina que el tamaño del bloque actual es menor que o igual al tamaño umbral (Si en el paso 20 S30021).
