Abstract

Un flujo de datos de video que tiene un video codificado en el mismo y se describe. Comprende primera información de temporización sobre primeros tiempos de remoción de búfer de imagen codificada, CPB, por aplicar en el lado del decodificador en caso de almacenar en búfer una versión completa del flujo de datos de video, y segunda información de temporización sobre segundos tiempos de remoción de CPB por aplicar en el lado del decodificador para almacenar en búfer una versión reducida del flujo de datos de video, que difiere del flujo de datos de video por la remoción de una porción del flujo de datos de video de la versión completa del flujo de datos de video. También se hace referencia a codificadores de video, decodificadores de video, nodos de red, aparatos para gestionar el búfer de imagen codificada, CPB, de un codificador de video, y aparatos para empalmar conjuntamente flujos de datos de video correspondientes.
