Abstract
Se proporciona un método, un aparato, un producto de programa de computadora y un medio leíble por computadora no transitorio para codificación de video. El método comprende realizar un proceso de intrapredicción de un bloque que comprende muestras que se van predecir, en donde un filtro de interpolación se aplica a muestras de referencia del bloque durante el proceso de intrapredicción del bloque. El filtro de interpolación se selecciona con base en un desplazamiento de subpíxel entre las muestras de referencia y las muestras que se van a predecir, y un tamaño de un lado de referencia principal usado en el proceso de intrapredicción se determina de acuerdo con una longitud del filtro de interpolación y un modo de intrapredicción que proporciona, fuera de un conjunto de modos de intrapredicción disponibles, el mayor valor no entero de este desplazamiento de subpíxel, en donde el lado de referencia principal comprende las muestras de referencia.
