Abstract

Un método para decodificar un flujo de bits de vídeo que comprende una secuencia de imágenes que comprende una imagen A y una imagen B, en el que la imagen A inicia un período de punto de recuperación y la imagen B finaliza el período de punto de recuperación. El método incluye obtener el flujo de bits de video y decodificar a partir del flujo de bits de video una indicación normativa del período del punto de recuperación. La indicación normativa del período del punto de recuperación indica que la imagen A inicia el período del punto de recuperación y / o que la imagen B finaliza el período del punto de recuperación.
