ABSTRACT:
Apparatus and methods are provided for generating a Huffman Code for use in compressing a received digital signal. The digital signal includes a plurality of digital sets wherein ones of the digital sets are non-unique. Ones of the digital sets are stored. Each stored digital set has associated therewith a codeword and an indicator. The indicator represents a probability of occurrence, or frequency, of the stored digital set within the digital signal. While more than one associated indicator remains stored, pairs of associated indicators are selectively combined and a first digital set associated with a first indicator and a second digital set associated with a second indicator are both associated with the selectively combined indicator. A first binary value is appended to the codeword associated with the first digital set and a second binary value is appended to the codeword associated with the second digital set.
