Abstract:
Video coding systems or apparatus utilizing context-based adaptive binary arithmetic coding (CABAC) during encoding and/or decoding, are configured according to the invention with an enhanced binarization of non-zero Delta-QP (dQP). During binarization the value of dQP and the sign are separately encoded using unary coding and then combined into a binary string which also contains the dQP non-zero flag. This invention capitalizes on the statistical symmetry of positive and negative values of dQP and results in saving bits and thus a higher coding efficiency.

Claim (Index 4):
The decoding apparatus according to  claim 2 , further comprising a determination unit configured to determine whether the difference quantization parameter is non-zero, based on a value that indicates the difference quantization parameter is non-zero,\n wherein the decoding unit is further configured decode the absolute value and the identification value, when the determination unit determines that the difference quantization parameter is non-zero.
