The value of ubset_seq_parameter_set_id_delta[i][j] shall not be greater than 31. When j is greater than 0, the value of subset_seq_parameter_set_id_delta[i shall not be equal to 0. When parameter_sets_info_present_flag[i is equal to 1, the primary coded VCL NAL units of the current scalable layer representation shall not refer to any subset sequence parameter set for which the value of parameter_se is not indicated by the syntax elements subset_seq_parameter_set_id_delta[i][j] for the current scalable layer and the syntax elements subset_seq_parameter_set_id_delta[i] for the current scalable layer shall not indicate any subset sequence parameter set that is not referenced in any primary coded VCL NAL unit of the current scalable layer representation. num_pic_parameter_sets_minus1[i]p plus 1 indicates the number of different picture parameter sets that are referred to by the primary coded VCL NAL units of the current scalable layer representation. The value of num_pic_parameter_sets_minus1[ shall be in the range of 0 to 255, inclusive. pic_parameter_set_id_delta[i][j] indicates the smallest value of the pic_parameter_set_id of any picture parameter set required for decoding the representation of the current scalable layer, if j is equal to 0. Otherwise greater than 0), pic_parameter_set_id_delta[i] indicates the difference between the value of the j-th required picture parameter set and the value of the pic parameter_set_ of the required picture parameter set for decoding the representation of the current scalable layer. The value of pic_parameter_set_id_delta[i][j] shall not be greater than 255. When j is greater than 0, the value of pic_parameter_set_id_delta[i]j shall not be equal to 0. When parameter_sets_info_present_flag[i is equal to 1, the primary coded VCL NAL units of the current scalable layer representation shall not refer to any picture parameter set for which the value
