摘要：
A method of encoding a plurality of adaptive filter coefficients (104, 107, 112) into a bitstream (110). The method comprises the steps of entropy encoding (109) the adaptive filter coefficients (104, 107, 112) into the bitstream (110), whereby a prediction (202) for an instance (204) of the adaptive filter coefficients is determined (201) based on at least one of the remaining adaptive filter coefficients (206), a prediction error (205) is determined (203) based on the difference between the instance (204) of the adaptive filter coefficients and the prediction (202), and wherein the step of entropy encoding (109) the plurality of adaptive filter coefficients (104, 107, 112) comprises entropy encoding (109) the prediction error (205) for the instance (204) of the adaptive filter coefficients and entropy encoding (109) the remaining adaptive filter coefficients (206). Further is provided a corresponding method of decoding a bitstream (110) of encoded adaptive filter coefficients into decoded adaptive filter coefficients (116, 118, 120, 123).
