ABSTRACT:
A method and system for generating a compressed domain, digital signal suitable for transmission, the method including: providing a first digital data stream signal including a first plurality of data bits and a second digital data stream signal including a second plurality of data bits; determining a threshold value for the first digital data stream signal; identifying select ones of the first plurality of bits dependent upon the threshold value; and, substituting data bits from the second plurality for the select bits of the first plurality to generate a composite digital data stream signal; wherein the composite digital data stream signal is adapted to be received and decoded by receivers adapted to receive the first digital data stream signal and receivers adapted to receive the composite digital data stream signal.
