0 for the slices of the current layer representation and all slices of the reference layer representation (with DQId equal to the value of ref_layer_dq_id). When slice_skip_flag is equal to 1, the value of constrained_intra_pred_flag for the current layer representation shall be identical to the value of constrained_intra_pred_flag for the reference layer representation (with DQId equal to ref_layer_dq_id). The variable MaxTCoeffLevelPredFlag is set equal to the maximum value of tcoeff_level_prediction_flag for the slices of the current layer representation. scan_idx_start specifies the first scanning position for the transform coefficient levels in the current slice. When scan idx start is not present, it shall be inferred to be equal to 0. scan_idx_end specifies the last scanning position for the transform coefficient levels in the current slice. When scan idx end is not present, it shall be inferred to be equal to 15. When default_base_mode_flag is equal to 1, (slice_type % 5) is equal to 2, and entropy_coding_mode_flagis equal to 0, it is a requirement of bitstream conformance that the value of scan_idx_end is greater than or equal to scan_idx_start. G.7.4.3.5 Decoded reference base picture marking semantics The specification of this clause applies to the current dependency representation. The modifications a) and b) specified in clause G.8.2 apply with currDependencyId being equal to the current value of dependency_ic The syntax elements adaptive_ref_base_pic_marking_mode_flag memory_management_base_control_operation, difference_of_base_pic_nums_minus1, and long_term_base_pic_num specify marking of reference base pictures as "unused for reference". When present in a prefix NAL unit, all syntax elements of the dec_ref_base_pic_marking() syntax structure are considered as if they were present in the associated NAL unit. When quality id is greater than 0, all syntax elements of the dec_ref_base_pic_marking() syntax structure are inferred as specified in the beginning of clause G.7.4.3.4. The content of the deco
