[Mp4-tech] about the parsing process of macroblock_layer( ) in H.264 decoding standart JVT_G050

[Yan Zheng]

hello,
  We find out that when decoding a macroblock of Intra_16x16(we use the entropy encode/decode of CABAC), the process as following is unimaginable skipped:
  if(CodedBlockPatternLuma>0 || CodedBlockPatternChroma>0 || MbPartPredMode(mb_type,0)==Intra_16x16){
  mb_qp_delta               se(v)|ae(v)
  }
  That means the SE of mb_qp_delta is not obtained by decoding the bitstream.Then how JM  gets the SE value?is this SE value obtained through other methods? (if so, how the standard be the standard?)
  Thank you all.
