modifications a) to d) specified in the first paragraph of this clause apply. idr_pic_id identifies an IDR picture when dependency id is equal to the maximum present value of dependency_ id in the VCL NAL units of the current coded picture. The value of idr_pic_id shall be in the range of 0 to 65535, inclusive. When two consecutive access units in decoding order are both IDR access units, the value of idr pic in the slices of the target dependency representation in the primary coded pictures of the first such IDR access unit shall differ from the idr_pic_id in the slices of the target dependency representation in the primary coded pictures of the second such IDR access unit. NOTE 2 - The classification of an access unit as IDR access unit depends on the maximum present value of dependency id. When NAL units are removed from a bitstream, e.g. in order to adjust the bitstream to the capabilities of a receiving device, the classification of access units as IDR access units may change. Since all bitstreams for different conformance points supported in a scalable bitstream (in particular for different maximum values of dependency_ must conform to this Recommendation | International Standard (as specified in clause G.8.8.1), the constraints on idr_pic_id must be obeyed for all conformance points contained in a scalable bitstream. pic_order_cnt_lsb, delta_pic_order_cnt_bottom, delta_pic_order_cnt[ and delta_pic_order_cnt[ have the same semantics as specified in clause 7.4.3. For this specification, the modifications a) to f) specified in the first paragraph of this clause apply. Rec. ITU-T H.264 (01/2012) redundant_pic_cn has the same semantics as specified in clause 7.4.3. For this specification, the modifications a) to g) specified in the first paragraph of this clause apply. direct_spatial_mv_pred_flag specifies the method used in the decoding process to derive motion vectors and reference indices for inter prediction. When quality_i is greater than 0,direct_spatial_mv_pred_flagis inferred as specified in beginning o
