 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. For all picture parameter set NAL units referred to by NAL units with nal_unit type equal to 1 or 5, change the value of seq parameter set id to be equal to the value of eq_parameter_se in a subset sequence parameter set NAL unit with profile_ido equal to 83 or 86 that is referred to by slices with equal to 20 of the current scalable layer. 2. Remove all NAL units with nal_unit_type equal to 20 and slice_skip_flag equal t to 1. 3. Remove all NAL units with nal_unit_type e equal to 14. 4. Remove all redundant coded VCL NAL units. In each access unit, remove all VCL NAL units with DQId less than DQIdMax, with DQIdMax being the maximum value of DQId in the primary coded slices of the access unit after removing the NAL units with nal_unit_type equal to 20 and slice_skip_flag equal to 1. 6. Remove the NAL unit header SVC extension from NAL units with nal_unit_type equal to 20. 7. For NAL units with nal_unit_type equal to 20 and dr_flag equal to 1, set nal_unit_type equal to 5. 8. For NAL units with nal_unit_type equal to 20 and idr flag equal to 0, set nal unit type equal to 1. 9. Remove all SEI NAL units. 10. Remove all NAL units with nal_unit_type equal to 7. 11. For all NAL units with nal_unit_type equal to 15, set 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_ido as specified Rec. ITU-T H.264 (01/2012) writing_profile_level_ide[i ][ entropy_coding_mode_flag] when present, and change RBSP trailing bits appropriately. conversion_type_idc[i] equal to 2 indicates that slice_header_restriction_flag in the subset sequence parameter sets referred to by the primary coded VCL NAL units of the current scalable layer is equal to 1, that no_inter_layer
