3D Huffman Tables
This SRD refers to a system of 3D Huffman decoding. The 3-dimensional table is laid out as such:
vc1DEC3DH_pACCodingSets +- 0: (inter) +- vc1DEC3DH_HighRateInter +- vc1DEC3DH_HighMotInter +- vc1DEC3DH_MidRateInter +- 1: (inter) +- vc1DEC3DH_LowMotInter +- vc1DEC3DH_HighMotInter +- vc1DEC3DH_MidRateInter +- 2: (intra) +- vc1DEC3DH_HighRateIntra +- vc1DEC3DH_HighMotIntra +- vc1DEC3DH_MidRateIntra +- 3: (intra) +- vc1DEC3DH_LowMotIntra +- vc1DEC3DH_HighMotIntra +- vc1DEC3DH_MidRateIntra
Thus, there are 8 AC coding sets used in 12 positions:
