Abstract:
An apparatus and method for encoding quantized frequency represented data, the data including zero and non-zero represented data. For zero represented data, a zero run length is determined. A Golomb parameter is determined as a logarithmic function of the zero run length. A quotient is encoded as a function of the zero run length and the Golomb parameter. A remainder is encoded as a function of the zero run length, the Golomb parameter and the quotient. The coded quotient and the coded remainder are concatenated.
