t_significant_coeff_flag, and coeffabs_level_minus1 Inputs to this process are ctxIdxOffset and binIdx. Output of this process is ctxIdxInc. The assignment process of ctxIdxInc for syntax elements significant_coeff_flag, last_significant_coeff_flag, and coeff abs_level_minus1 as well as for coded_block_flag depends on categories of different blocks denoted by the variable ctxBlockCat. The specification of these block categories is given in Table 9-42. Rec. ITU-T H.264 (01/2012) Table 9-42 - Specification of ctxBlockCat for the different blocks Block description maxNumCoeff ctxBlockCat block of luma DC transform coefficient levels (i.e., list Intra16x16DCLevel as described in clause 7.4.5.3) block of luma AC transform coefficient levels (i.e., list Intra16x16ACLevel[ i ] as described in clause 7.4.5.3) block of 16 luma transform coefficient levels (i.e., list LumaLevel4x4| ] as described in clause 7.4.5.3) block of chroma DC transform coefficient levels when ChromaArrayType is equal to 1 or 2 4* NumC8x8 (i.e., list ChromaDCLevel as described in clause 7.4.5.3) block of chroma AC transform coefficient levels when ChromaArrayType is equal to 1 or 2 (i.e., list ChromaACLevel as described in clause 7.4.5.3) block of 64 luma transform coefficient levels (i.e., list LumaLevel8x8[ i ] as described in clause 7.4.5.3) block of Cb DC transform coefficient levels when ChromaArrayType is equal to 3 (i.e., list CbIntral6x16DCLevel as described in clause 7.4.5.3) block of Cb AC transform coefficient levels when ChromaArrayType is equal to 3 (i.e., list CbIntra16x16ACLevel[ i ] as described in clause 7.4.5.3) block of 16 Cb transform coefficient levels when ChromaArrayType is equal to 3 (i.e., list CbLevel4x4[ i ] as described in clause 7.4.5.3) block of 64 Cb transform coefficient levels when ChromaArrayType is equal to 3 (i.e., list CbLevel8x8[ i ] as described in clause 7.4.5.3) block of Cr DC transform coefficient levels when ChromaArrayType is equal to 3 (i.e., list CrIntral6x16DCLevel as described in clause 7.4.5.3) block
