ABSTRACT:
A data processing system includes a subband decomposition of a source signal by encoding of the significant pyramid-type subband representation. During the encoding process, M-array is used for initialization of set of arrays Si(arrays of solution bits), which define the order of creating output data streams. Output data streams contain an encoded significance map and values of (significant) non-zero subband decomposition coefficients adapted for successive quantization and entropy encoding.
