Abstract

La presente invención se refiere a un sistema de transmisión digital que comprende a un transmisor y a un receptor, para transmitir una señal digital de banda amplia con una frecuencia de muestreo específica Fs, por ejemplo una señal de audio digital, a través de un medio de transmisión y para recibir dicha señal, el transmisor tiene una terminal de entrada para recibir la señal digital de banda amplia, dicha terminal de entrada se acopla con una entrada de una fuente de señal que forma parte del transmisor y que se construye de manera tal que genere una segunda señal digital y que envíe dicha señal digital a una salida, dicha segunda señal digital comprende cuadros consecutivos, cada cuadro comprende varios paquetes de información, cada paquete de información comprende N bits, N es mayor que 1, el receptor comprende un decodificador que tiene una entrada para recibir la segunda señal digital, dicho decodificador tiene una salida acoplada con una terminal de salida para alimentar la señal digital de banda amplia, caracterizado porque si P en la fórmula P BR/N * ns/Fs, es un número ntero donde, BR es la velocidad de bits de la segunda señal digital y ns es el número de muestras de la señal digital de banda amplia cuya información correspondiente, que pertenece a la segunda señal digital, se incluye en un cuadro de la segunda señal digital, el número de paquetes de información B en un cuadro es P, y porque si P no es un número entero, el número de paquetes de información en un número de cuadros, es P', donde P' es el número entero inferior siguiente después de P, y el número de paquetes de información en los otros cuadros es igual a P' + 1 de manera que se cumple exactamente con el requisito de que la velocidad de cuadro promedio de la segunda señal digital, sea sustancialmente igual a Fs/ns y de que un cuadro debe comprender por lo menos una primera porción de cuadro que incluye información de sincronía.
