Abstract
Se proporciona un método de procesamiento de video que comprende: mantener, antes de una conversión entre un bloque de video actual de una región de video y una representación codificada del video, al menos una tabla de predicción de vector de movimiento basada en historia (HMVP), en donde la tabla de HMVP incluye una o más entradas correspondientes a la información de movimiento de uno o más bloques procesados anteriormente; y realizar la conversión utilizando al menos una tabla de HMVP; y en donde la información de movimiento de cada entrada está configurada para incluir información del filtro de interpolación para uno o más de los bloques procesados previamente, en donde la información del filtro de interpolación indica filtros de interpolación utilizados para interpolar bloques de predicción de uno o más de los bloques procesados previamente.
