Claim 20:
21. A node for applying filtering to a media object comprising a plurality of samples, the node configured to:
apply a set of offset values to a set of coefficients, wherein the set of coefficients are inverse quantized coefficients, wherein each offset value of the set of offset values corresponds to a separate coefficient of the set of coefficients, and wherein applying the set of offset values comprises:
determining whether a coefficient value is larger than a positive threshold or smaller than a negative threshold, and
applying a corresponding offset value to the coefficient value based on the determination whether the coefficient value is larger than the positive threshold or smaller than the negative threshold, such that, if the coefficient value is larger than the positive threshold, then adding the corresponding value to the coefficient value, and if the coefficient value is smaller than the negative threshold, then subtracting the corresponding value from the coefficient value; and

after applying the set of offset values, apply the filtering.
