Abstract
Las formas de realización reducen el retardo de salida de las imágenes determinando, una vez decodificada y almacenada la imagen actual en un búfer de imágenes decodificadas, DPB, una cantidad de imágenes del DPB que están marcadas como necesarias para la salida. Esa cantidad se compara, una vez decodificada y almacenada la imagen actual y en el, con un valor derivado de al menos un elemento de sintaxis presente o que debe estar presente en una corriente de bits (10) que representa las imágenes de una secuencia de video. Si esa cantidad es mayor que el valor es preferentemente se da salida y se marca como no necesaria para la salida una imagen, que es la primera imagen en el orden de salida de las imágenes del DPB que están marcadas como necesarias para la salida; Método; Codificador; Terminal; Nodo.
