Data elements, preferably representative of video data, are logically divided into blocks. In a bit-wise fashion, each block is inspected to determine whether the data elements for that block may be represented in a highly compact format. If a given block may not be represented in this manner, it is sub-divided into blocks having smaller dimensions. This process of identifying suitable blocks and sub-dividing is recursively repeated until minimum block dimensions are reached. The same result may be achieved through the use of a plurality of ascending tables that are constructed by repetitively forming tables of reduced data elements. The plurality of ascending tables is traversed and, based on the reduced data elements, blocks of data are identified that are susceptible to the highly compact format. Wavelet transforms are preferably used to provide video data to be compressed.
