Abstract

Un método determina una pluralidad de filtros de interpolación para uso en la interpolación de valores de sub-pel para un proceso de predicción temporal de contenido de video; la pluralidad de filtros de interpolación están diseñados con base en compensaciones de sub-pel para dos bloques de referencia; el método determina una primera compensación de sub-pel para un primer bloque de referencia para la unidad de contenido de video y determina una segunda compensación de sub-pel para un segundo bloque de referencia para una unidad de contenido de video; un conjunto de filtros de interpolación es determinado para interpolar un conjunto de valores de píxel de sub-pel para uso en el proceso de predicción temporal para la unidad de contenido de video; el conjunto de filtros de interpolación está diseñado para la primera compensación de sub-pel y la segunda compensación de sub-pel y se utiliza para interpolar un primer valor de píxel de sub-pel para el primer bloque de referencia y un segundo valor de sub-pel para el segundo bloque de referencia.
