Abstract

La presente invención se refiere a un codificador de video para codificación predictiva de una corriente de video de tramas subsiguientes de acuerdo con una compensación de movimiento hacia una corriente de bis de video codificada, que comprende una memoria intermedia de tramas (207) configurada para almacenar al menos una trama de referencia de la corriente de video, una unidad de producción (210) configurada para generar un bloque de producción de un bloque actual de una trama actual a partir de un bloque de referencia de la trama de referencia de acuerdo con un vector de movimiento que tiene resolución fraccional de pel, la resolución fraccional de pel define una posición entera de pel y posiciones fraccionales de pel. La unidad de predicción (210) se configura para interpolar el bloque de referencia de acuerdo con la resolución fraccional de pel mediante uno de al menos tres filtros de interpolación siguientes: un filtro de interpolación de esfumado (302), un filtro de contacto (303) y el filtro de contacto (303) seguido de un filtro de definición (311).
