Abstract

A TRANSMITTER IS DISCLOSED FOR TRANSMITTING A DIGITAL INFORMATION SIGNAL HAVING M BIT PCM SAMPLES VIA A TRANSMISSION MEDIUM. THE M BIT PCM SIGNAL IS SPLIT (8) INTO A P BIT PCM SIGNAL, WHEREBY P<M AND A DIFFERENCE SIGNAL. THE P BIT PCM SIGNAL IS A LOWER QUALITY REPRESENTATION OF THE M BIT PCM DIGITAL INFORMATION SIGNAL AND THE DIFFERENCE SIGNAL IS OBTAINED BY SUBTRACTING THE P BIT PCM SIGNAL FROM THE M BIT PCM SIGNAL. THE DIFFERENCE SIGNAL IS DATA COMPRESSED (16) SO AS TO OBTAIN A DATA COMPRESSED DIFFERENCE SIGNAL.THE P BIT PCM SIGNAL AND THE DATA COMPRESSED DIFFERENCE SIGNAL ARE COMBINED (24) SO AS TO OBTAIN A TRANSMISSION SIGNAL. THE TRANSMISSION SIGNAL IS TRANSMITTED VIA THE TRANSMISSION MEDIUM (TRM).(FIG. 1)
