Abstract

Un dispositivo de procesamiento de video obtiene un flujo de datos que comprende una pluralidad de flujos elementales y un descriptor de la sincronizacion de codificacion de video de alta eficiencia (HEVC) y el decodificador de referencia hipotetico (HRD). El descriptor de la sincronizacion de HEVC y el HRD comprenden un elemento de sintaxis del indice de programacion deseado que indica un indice de programacion de entrega. El dispositivo de procesamiento de video puede identificar, sobre la base de un conjunto de parametros, un elemento de sintaxis en una matriz de elementos de sintaxis en un conjunto de parametros de video (VPS). El conjunto de parametros puede comprender un parametro que tiene un valor igual a un valor del elemento de sintaxis del indice de programacion deseado. El dispositivo de procesamiento de video puede identificar, sobre la base de un indice especificado por el elemento de sintaxis identificado, una estructura de sintaxis de los parametros del HRD particular de una pluralidad de estructuras de sintaxis de los parametros del HRD que puede aplicarse a un flujo elemental particular
