The value of num_seq_parameter_sets[i] shall be in the range of 0 to 32, inclusive. seq_parameter_set_id_delta[i][j] indicates the smallest value of the q_parameter id of any sequence parameter set required for decoding the representation of the current scalable layer, if j is equal to 0. Otherwise (j is greater than 0), q_parameter_set_id_delta[i][j indicates the difference between the value of the seq_parameter_set_id of the j-th required sequence parameter set and the value of the seq parameter_se of the 1)-th required sequence parameter set for decoding the representation of the current scalable layer. The value of seq parameter i ][ shall not be greater than 31. When j is greater than 0, the value of _parameter_set_id_delta shall not be equal to 0. When parameter_sets_info_present_flag| ] is equal to 1, the primary coded VCL NAL units of the current scalable layer representation shall not refer to any sequence parameter set for which the value of parameter_: set id is not indicated by the syntax elements seq i for the current scalable layer and the syntax elements seq_parameter_set_id_delta[i][j for the current scalable layer shall not indicate any sequence parameter set that is not referenced in any primary coded VCL NAL unit of the current scalable layer representation. num_subset_seq_parameter_setsi] indicates the number of different subset sequence parameter sets that are referred to by the primary coded VCL NAL units of the current scalable layer representation. The value of num_subset_seq_parameter_sets[i) shall be in the range of 0 to 32, inclusive. subset_seq_parameter_set_id_deltai][j] indicates the smallest value of the q_parameter_set_i of any subset sequence parameter set required for decoding the representation of the current scalable layer, if j is equal to 0. Otherwise (j is greater than 0), pset_seq_parameter_set_id_delta[i][ indicates the difference between the value of the eq_parameter_set_id of the j-th required subset sequence parameter set and the value of the seq
