Abstract

RESUMEN Un dispositivo de ejemplo para codificar datos de video incluye una memoria configurada para almacenar datos de video, y uno o más procesadores implementados en circuito y configurados para codificar una primera diferencia de vectores de movimiento (MVD) que representa una diferencia entre un primer vector de movimiento de un bloque actual de datos de video predicho usando predicción afín y un primer predictor de vectores de movimiento (MVP) para el primer vector de movimiento, predecir una segunda MVD de la primera MVD para un segundo vector de movimiento del bloque actual, y codificar el bloque actual usando predicción afín de acuerdo con el primer vector de movimiento y el segundo vector de movimiento. La predicción de la segunda MVD de la primera MVD de esta forma puede reducir la tasa de bits de una corriente de bits que incluye datos de video codificados, así como mejorar la eficacia de procesamiento.
