Abstract

Se proporciona un transmisor de emisión digital. El transmisor incluye una unidad de inserción de datos conocidos los cuales insertan un dato conocido al flujo, y una unidad de codificación de entramado la cual codifica el flujo secuencialmente utilizando una pluralidad de codificadores de entramado, en donde las unidades de inserción de datos conocidos insertan los datos conocidos a un sitio específico del flujo, de modo tal que los datos conocidos puedan ser codificados por entramado mediante por lo menos un codificador de entramado específico.
