 of pic_parameter_set_id is not indicated by the syntax elements pic parameter_set_id_delta[i ][ for the current scalable layer and the syntax elements pic parameter_set_id_delta[ i [[]] for the current scalable layer shall not indicate any picture parameter set that is not referenced in any primary coded VCL NAL unit of the current scalable layer representation. parameter_sets_info_src_layer_id_delta[i] greater than 0 indicates that the values of seq_parameter_set of the sequence parameter sets and subset sequence parameter sets and the values of c_parameter_set_id of the picture parameter sets that are referred to by the primary coded VCL NAL units of the current scalable layer representation are the same as those that are referred to by the primary coded VCL NAL units of the representation of the scalable layer b with the layer identifier layer_id[b] equal to layer_id[i parameter_sets_info_src_layer_id_delta[i]. When parameter_sets_info_src_layer_id_delta[i is greater than 0, the scalability information SEI message shall contain Rec. ITU-T H.264 (01/2012) information for a scalable layer b with layer id[ b ] equal to layer_id 1-parameter_sets_info_src_layer_id_deltal and this information shall not contain a value of parameter_sets_info_src_layer_id_delta[b] equal to 0. parameter_sets_info_src_layer_id_delta[ i ] equal to 0 indicates that the values of seq_parameter_set_id of the sequence parameter sets and subset sequence parameter sets and the values of pic_parameter_set_id of the picture parameter sets that are referred to by the primary coded VCL NAL units of the current scalable layer representation are not indicated in the scalability information SEI message. The value of parameter_sets_info_src_layer_id_delta[ i shall be in the range of 0 to layer_id[i], inclusive. notion_vectors_over_pic_boundaries_flag[ indicates the value of motion_vectors_over_pic_boundaries_flag as specified in clause E.2.1, that applies to the current scalable layer representation. max_bytes_per_pic_denom| indicates the value of ma
