Abstract

Se descubre un sistema de transmision digital que tiene un transmisor (11) y un receptor (12) para transmitir y recibir una señal digital de audio. La señal digital de audio está en la forma de muestras de una longitud específica (WL) de palabra y se presenta a una velocidad específica de muestra. El transmisor consta de una terminal (25, 30, 32) de entrada para recibir la señal digital de audio y para recibir la primera palabra (IW1) de informacion que tiene una relacion con la longitud específica de palabra y una segunda palabra (IW2) de informacion que tiene una relacion con la velocidad específica de muestra. Está presente una unidad (28) de formateo para combinar la señal digital de audio y la primera y segunda palabras de informacion dentro de una corriente de datos en serie apropiada para la transmision por medio de un medio de transmision (TRM, 12). La longitud (WL) de palabra de las muestras en la señal digital de audio, expresada en numero de bits, que es igual a n, en donde n es un entero mayor a cero, y la velocidad de muestra es igual a 2P.Fs, en donde P es un entero mayor a cero y Fs es igual a un valor de frecuencia tomada de un grupo de por lo menos dos valores de frecuencia, cada grupo de valores de frecuencia incluye 44.1 kHz y 48 kHz. El receptor consta de un convertidor (41) de velocidad de muestra para convertir la velocidad de muestra de la señal recibida.
