Abstract

La información de sincronización de la recuperación del decodificador, la información ROI y la información de identificación del mosaico son transmitidas dentro de un flujo de datos de video al nivel que permite un acceso fácil por las entidades de la red, tales como MANE o un decodificador. Con el fin de alcanzar tal nivel, al información de tales tipos se transporta dentro de un flujo de datos de video, por medio de paquetes intercalados en los paquetes de unidades de acceso de un flujo de datos de video. De acuerdo con una modalidad, los paquetes intercalados son de un tipo de paquete retirable, es decir, la eliminación de estos paquetes intercalados mantiene la capacidad del decodificador de recuperar completamente el contenido de video transportado vía el flujo de datos de video.
