Offset = 276 is assigned to the syntax element end of _slice_flag and the bin of mb _type, which specifies the I PCM macroblock type as further specified in clause 9.3.3.1. For parsing the value of the corresponding bin from the bitstream, the arithmetic decoding process for decisions before termination (DecodeTerminate) as specified in clause 9.3.3.2.4 is applied. NOTE - The bins of mb_type in I slices and the bins of the suffix for mb_type in SI slices that correspond to the same value of binIdx share the same ctxIdx. The last bin of the prefix of mb_type and the first bin of the suffix of mb_type in P, SP, and B slices may share the same ctxIdx.
