Abstract
Un método de codificación de video, en donde el método comprende el procesamiento de inter-predicción de un primer bloque, en donde el proceso de inter-predicción comprende filtrado de interpolación de subpixeles de muestras de un bloque de referencia; procesamiento de intra-predicción de un segundo bloque, en donde el procesamiento de intra-predicción comprende filtrado de interpolación de subpixeles de muestras de referencia; en donde el método además comprende seleccionar coeficientes de filtro de interpolación para el filtrado de interpolación de subpixeles basándose en un desplazamiento de subpixeles entre las posiciones de muestra de referencia de número entero y las posiciones de muestras de referencia de fracción, en donde para los mismos desplazamientos de subpixeles se seleccionan los mismos coeficientes de filtro de interpolación para el procesamiento de intra-predicción y el procesamiento de inter-predicción.
