Patent ID: 7088271

Claim:
Method for decoding a coded bit stream which represents a binarized representation of the data value, the binarized representation of the data value being a codeword having a primary prefix, which is a binarization of the minimum of the data value and a predetermined cut-off value in accordance with a first binarization scheme and, if the data value is greater than the predetermined cut-off value, a primary suffix appended to the primary prefix, the primary suffix being a binarization of the difference of the data value minus the predetermined cut-off value in accordance with a second binarization scheme, the method comprising the following steps: for each bit in the codeword, if the bit of the codeword is part of the primary prefix, determining the bit by binary arithmetically decoding the coded bit stream by means of a adaptively varying bit value probability estimation; and if the bit of the codeword is part of the primary suffix, determining the bit by binary arithmetically decoding the bit by means of a static bit value probability estimation, thereby obtaining the codeword representing the data value.
