  • Method and apparatus for selectively discarding data when required in order to achieve a desired Huffman coding rate
    Patent number: 5872599
    Abstract: 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.
