Claim:
1. A method for decoding a bitstream associated with transform coefficients comprising the steps of: (a) obtaining a bitstream; (b) decoding binary data associated with a target transform coefficient from the obtained bitstream by using an arithmetic decoding; (c) deriving a Rice parameter for said target transform coefficient; (d) receiving an indicator from the bitstream, wherein the indicator is a flag that is different from the Rice parameter: (e) determining, based on the indicator, whether a first code or a second code is to be used in combination with a Rice code corresponding to the Rice parameter; and (f) converting said binary data to a parameter associated with magnitude of said target transform coefficient based on a combination of the Rice code and the determined first or second code, wherein the first code is a k-th order exponential Golomb code.
