Abstract

Un procedimiento implementado por ordenador de decodificación de vídeo con un decodificador, comprendiendo el procedimiento: en el decodificador, recibir un flujo de bits de datos codificados para un clip de vídeo determinado generado por un codificador (202), en el que se proporcionan N conjuntos de parámetros (214) para el flujo de bits de datos codificados para el clip de vídeo determinado, en el que N es mayor que o igual a 2, en el que cada uno de los N conjuntos de parámetros (214) comprende un parámetro de velocidad y un parámetro de tamaño de memoria intermedia de decodificador, en el que cada uno de los N conjuntos de parámetros (214) caracteriza un modelo de contador dinámico de un decodificador (210) de referencia para el flujo de bits de datos codificados para el clip de vídeo determinado, estando además el modelo de contador dinámico para cada uno de los N conjuntos de parámetros (214) caracterizado por un nivel de llenado de memoria intermedia de decodificador inicial o un retardo de memoria intermedia inicial; en el decodificador, recibir información que indica cuántos conjuntos de parámetros se proporcionan para el flujo de bits de datos codificados para el clip de vídeo determinado; y en el decodificador, decodificar los datos codificados para el clip de vídeo determinado, en el que los N conjuntos de parámetros (214) están disponibles para su uso en la determinación de una condición operativa, y en el que la condición operativa es la velocidad pico mínima o el tamaño de memoria intermedia de decodificador mínimo para la decodificación de los datos codificados para el clip de vídeo determinado.
