Abstract

Un transmisor transmite sucesivos campos de datos, y cada campo de datos incluye una mezcla de segmentos de datos de VSB y segmentos de datos de E-VSB y porciones intercaladas de mapas. Los mapas definen las mezclas de segmentos de datos de VSB y segmentos de datos de E-VSB en correspondientes campos de datos a ser transmitidos después que correspondientes mapas son transmitidos. Antes de la intercalación, los mapas son codificados. En un receptor, los mapas son desintercalados y decodificados de modo de deducir la mezcla de segmentos de datos de VSB y segmentos de datos de E-VSB que definen cada uno de los campos de datos. La intercalación y la desintercalación tienen una latencia combinada de por lo menos L campos. Los segmentos de datos de VSB y los segmentos de datos de E-VSB de cada uno de los campos de datos son separados en respuesta a los mapas desintercalados.
