For the syntax elementssignificant_coeff_flagand last_significant_coeff_flag in blocks with ctxBlockCat not equal to 3, 5, 9, and 13, the variable ctxIdxInc is derived by ctxIdxInc = levelListIdx (9-21) where levelListIdx ranges from 0 to maxNumCoeff - 2, inclusive. For the syntax elements significant_coeff_flag and last_significant_coeff_flag in blocks with ctxBlockCat = 3, the variable ctxIdxInc is derived by ctxIdxInc = Min( levelListIdx/NumC8x8, 2) (9-22) where levelListIdx ranges from 0 to 4 * NumC8x8 2, inclusive. For the syntax elements significant_coeff_flag and st_significant_coeff flag in 8x8 luma, Cb, or Cr blocks with ctxBlockCat = = 5, 9, or 13, Table 9-43 contains the specification of ctxIdxInc for the given values of levelListIdx, where levelListIdx ranges from 0 to 62, inclusive.

ITU-T H.264 (01/2012) Table 9-43 - Mapping of scanning position to ctxIdxInc for ctxBlockCat = = 5, 9, or 13 Let numDecodAbsLevelEq1 denote the accumulated number of decoded transform coefficient levels with absolute value equal to 1, and let numDecodAbsLevelGt1 denote the accumulated number of decoded transform coefficient levels with absolute value greater than 1. Both numbers are related to the same transform coefficient block, where the current decoding process takes place. Then, for decoding of coeff_abs_level_minusl, ctxIdxInc for coeff_abs_level_minus) is sp
