Abstract
Las modalidades reducen el retraso de salida para las imágenes mediante la determinación después de que una imagen actual ha sido decodificada y se almacenan en una memoria intermedia de imágenes decodificadas, DPB, (125, 225, 325, 425, 525, 625), un número de imágenes en el DPB (125, 225, 325, 425, 525, 625) que están marcadas como sea necesario para la salida. Este número se compara, después de que una imagen actual ha sido decodificada y almacenada en el DPB (125, 225, 325, 425, 525, 625), en contra de un valor derivada desde al menos un elemento de sintaxis presente o para estar presentes en un flujo de bitios (10) que representa las imágenes de una secuencia de vídeo. Si este número es mayor que el valor de una imagen, la cual es la primera imagen en orden de salida, de las imágenes en el DPB (125, 225, 325, 425, 525, 625) que están marcadas como sea necesario para la salida es preferiblemente de salida y marcado como no sea necesario para la salida.
