Abstract

La presente invención da a conocer un método de decodificación de vídeo realizado por un dispositivo de decodificación de vídeo. El método de decodificación de vídeo de acuerdo con una modalidad puede incluir los pasos de: obtener información de tipo de unidad NAL que indica un tipo de una unidad de capa de abstracción de red (NAL) actual de un flujo de bits; y decodificar, cuando la información de tipo de unidad NAL indica que el tipo de unidad NAL de la unidad NAL actual es un dato codificado para un corte, el corte basado en si se aplica un tipo de unidad NAL mixta a una imagen actual.
