Abstract

Se describe un método de decodificación de vídeo según una modalidad, el método comprende: un paso para comparar el tamaño de un vídeo actual que incluye un bloque actual y el tamaño de un vídeo de referencia; un paso para seleccionar un bloque de referencia, que incluye muestras de referencia correspondientes a muestras actuales en el bloque actual, desde dentro del vídeo de referencia según un vector de movimiento del bloque actual; y un paso para restaurar el bloque actual sobre la base del bloque de referencia. Cuando el tamaño del vídeo de referencia es mayor que el del vídeo actual, las respectivas muestras de referencia se separan dentro del vídeo de referencia a intervalos correspondientes a un resultado de comparación de tamaño.
