摘要： A data processing system includes a subband decomposition of a source signal by encoding of the significant pyramid-type subband representation. While 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.

摘要： A method of video data transmitting (3) by means of video data reconstruction on the receiving end of the communication channel per time unit (4), based not only on the data transmitted directly via the channel but on all previously transmitted, decoded and stored video data (6).
