Apparatus and methods are provided for generating an output signal representing a selectively reduced coding rate for use in compressing a digital signal. The digital signal includes a plurality of digital sets wherein at least one of the digital sets are non-unique. A current coding rate and a threshold coding rate compared to determine whether the current coding rate satisfies a predetermined criteria. In response to the determination, at least one of the digital sets are selectively discarded, a rate difference resulting from selectively discarding at least one of the plurality of digital sets is determined, and the current coding rate is recalculated using the determined rate difference.

[ I claim:] [1.] A method for generating an output signal representing a coding rate for use in compressing a digital signal, said digital signal including a plurality of digital sets representing the symbols to be coded wherein at least one of said plurality of digital sets is non-unique, said method comprising the steps of:(a) receiving a signal representing a current coding rate;(b) comparing said current coding rate with a threshold coding rate to determine whether said current coding rate satisfies a predetermined criterion;(c) discarding selectively, upon a determination that said current coding rate fails to satisfy said predetermined criterion, at least one of said plurality of digital sets, determining a rate difference resulting from selectively discarding said at least one of said plurality of digital sets, and recalculating said current coding rate using said rate difference; and(d) generating said output signal using said current coding rate.
