Abstract

Se proporciona un método de decodificación. El método incluye recibir un subflujo de bits que tiene un conjunto de parámetros de secuencia (SPS) con una estructura de sintaxis de memoria intermedia de imágenes decodificadas (DPB) para un conjunto de capas de salida (OLS) con una única capa; establecer un número de capas en el OLS igual a uno con base en el OLS que tiene la única capa; obtener la estructura de sintaxis DPB para el OLS con la única capa del SPS cuando el número de capas en el OLS se ha establecido igual a uno; y decodificar una imagen de la única capa usando la estructura de sintaxis DPB para obtener una imagen decodificada. También se proporciona un método de codificación correspondiente.
