BigPatents India

A method for processing bit symbols generated by a data source, in particular a video, still image or audio source, comprising the following steps of contracting a plurality of bit-planes from the data source, each bit-plane comprising a plurality of bit-planes symbols; scanning the bit-plane symbols of each bit-plane to generate a binary string of bit-plane symbols; and encoding the binary string of the bit-plane symbols using a statistical model, wherein the statistical model is based on statistical properties of a Laplacian probability distribution function which characterizes the data source.
