Abstract
Un sistema de recepcion VSB incluye un generador de secuencia para decodificar un símbolo que corresponde a los datos suplementarios y generar una secuencia predefinida incluida en los datos suplementarios en el sistema de transmision VS.El sistema de recepcion además incluye un receptor VSB heredado modificado para procesar los datos recibidos del sistema de transmision VSB en orden inverso con relacion al sistema de transmision VSB utilizando la secuencia, y un desmultiplexor para desmultiplexar los datos del receptor VSB heredado modificado en los datos MPEG y los datos suplementarios. El sistema de recepcion VSB además incluye un procesador de datos suplementarios para procesar el segmento de datos suplementarios del desmultiplexor en orden inverso con relacion al sistema de transmision, a fin de obtener los datos suplementarios, por medio de lo cual se practica la prediccion de rebanador, la decodificacion, y la decision de símbolos de una manera más precisa mediante el uso de la secuencia predefinida, con el objeto de mejorar un rendimiento.
