ABSTRACT:
Data compression is effected on arbitrary high entropy digitized data by compression and entropy transformation in an iterative system. Compression includes nonlinear addressing. Entropy transformation may involve any of a number of techniques to reorder distribution of data for testing to determine if the newly ordered data is compressible. Among the techniques are a merge technique, a swapping technique and various arithmetic modification techniques.
