Inputs to this process are: a variable fieldMbFlag specifying whether the current macroblock is a field or a frame macroblock, a variable bitDepth specifying the bit depth, a variable qP specifying the quantisation parameter value, a variable cO specifying the first coefficient index in the list of scaled transform coefficient values sTCoeff and in the list of transform coefficient values tCoeffLevel, a variable coeffDCLevel representing Intra16x16DCLevel, CbIntral6x16DCLevel, or CrIntra16x16DCLevel, a variable coeffACLevel representing Intra16x16ACLevel, CbIntra16x16ACLevel, or CrIntra16x16ACLevel, a variable coeffLevel4x4 representing LumaLevel4x4, CbLevel4x4, or CrLevel4x4, a list of scaled transform coefficient values sTCoeff with (256+2* MbWidthC* MbHeightC) elements, a list of transform coefficient level values tCoeffLevel with (256 + 2 * MbWidthC MbHeightC) elements. Outputs of this process are: a modified version of the list sTCoeff, a modified version of the list tCoeffLevel. NOTE 1 - When tcoeff_level_prediction_flag is equal to 0, this clause is always invoked as part of an invocation clause G.8.5.1 with refinementFlag equal to 0, in which case all elements of the list tCoeffLevel are set equal to 0 before invoking this clause. Rec. ITU-T H.264 (01/2012) For the DC transform coefficients of all residual 4x4 blocks, the following ordered steps are specified: 1. Depending on base_mode_flag, the 4x4 array C with elements Cii is derived as follows: If is equal to 0, the inverse scanni
