Title: Apparatus and method for entropy coding

Abstract: A quantified symbol stream is sampled, using the quantified symbols priorto the current symbol, to generate a modeling value that characterizes thestream. The modeling value is used to generate, or retrieve, a probabilityfunction that provides the probability that the current symbol will be thenext symbol in the symbol stream. The probability given by the probabilityfunction is then used to select the used to represent the data. Theencoded symbol is later decoded using the characteristics of the code, andan identical probability function, to determine the value of the originalquantified symbol.
