Abstract

Un método de decodificación de imágenes de conformidad con la presente invención comprende los pasos de: derivar un búfer de predicción de vector de movimiento basada en el historial (HMVP) para un bloque actual; derivar información de movimiento del bloque actual sobre la base de un candidato de HMVP incluido en el búfer de HMVP; generar muestras de predicción para el bloque actual sobre la base de la información de movimiento; y generar muestras de restauración sobre la base de las muestras de predicción, en donde el búfer de HMVP se inicializa cuando se procesa una primera CTU de una fila de CTU, en la que se coloca una CTU actual que incluye el bloque actual.
