_pred_flag is equal to 1 in all primary coded VCL NAL units of the current scalable layer, and that the alternative set of access units obtained by applying the following operations in sequential order to the current scalable layer representation conforms to one or more of the profiles specified in Annex A: 1. Remove all NAL units with nal_unit_type equal to 14. 2. Remove all redundant coded VCL NAL units. 3. In each access unit, remove all VCL NAL units with DQId less than DQIdMax. Remove the NAL unit header SVC extension from NAL units with unit equal to 20. 5. For NAL units with nal_unit_type equal to 20 and idr_flag equal to 1, set nal_unit_type equal to 5. 6. For NAL units with nal_unit_type equal to 20 and idr_flag equal to 0, set nal_unit_type equal to 1. 7. Remove all SEI NAL units. 8. Remove all NAL units with nal_unit_type equal to 7. For all NAL units with nal_unit_type equal to 15, set nal_unit_type equal to 7, remove all the syntax elements after the syntax structure seq_parameter_set_data() and before the rbsp_trailing_bits() syntax structure, replace the three bytes starting from profile_idc as specified rewriting profile_level_idc[ ][ entropy_coding_mode_flag ], when present, and change RBSP trailing bits appropriately. The value of conversion_type_idc[i shall be in the range of 0 to 2, inclusive. For the following syntax elements rewriting_info_flag[i][ rewriting_profile_level_idc[i[j] rewriting_avg_bitrate[i][j and rewriting_max_bitrate[i][j the variable j specifies the value of entropy_coding_mode_flag for all picture parameter set NAL units that are referenced in the VCL NAL units of the alternative set of access units obtained by converting the current scalable layer representation, with values for j equal to 0 or 1 indicating use of the CAVLC or CABAC entropy coding methods, respectively. NOTE 18 - It might be possible to convert the current scalable layer representation into two alternative sets of access units that conform to one or more of the profiles specified in Annex A, with one of th
