Abstract

Un método de codificación de imágenes para codificar una o más unidades que están incluidas en una imagen, que comprende: generar una primera bandera que indica si sí o no se fija por unidad (S221) un tiempo de eliminación de datos codificados de un búfer para almacenar los datos codificado mediante un decodificador hipotético; generar una segunda bandera que indica si es constante o arbitrario un intervalo entre los tiempos de eliminación de las unidades cuando el tiempo de eliminación se fija por unidad (S222); y generar una corriente de bits codificada que incluye los datos codificados, la primera bandera y la segunda bandera (S223).
