ginning of clause G.7.4.3.4. G.7.4.3.2 Prediction weight table semantics The semantics specified in clause 7.4.3.2 apply. When quality_id is greater than 0, all syntax elements of the pred_weight_table() syntax structure are inferred as specified in the beginning of clause G.7.4.3.4. G.7.4.3.3 Decoded reference picture marking semantics The semantics specified in clause 7.4.3.3 apply with substituting "SVC sequence parameter set" for "sequence parameter set" and with considering the reference pictures marked as "reference base pictures" as not present. The constraints specified in clause 7.4.3.3 apply only to the dependency representation with dependency_i id equal to the current value of dependency_id and the modifications a) and b) specified in clause G.8.2 apply with currDependencyId being equal to the current value of dependency_id When quality_id is greater than 0, all syntax elements of the dec_ref_pic_marking() syntax structure are inferred as specified in the beginning of clause G.7.4.3.4. In addition to the constraints specified in clause 7.4.3.3, the following constraints are specified: Rec. ITU-T H.264 (01/2012) a) When decoding a frame, the dec_ref_pic_marking() syntax structure shall not contain a memory_management_control_operation command equal to 3 that assigns a long-term frame index to a complementary reference field pair (not marked as "reference base picture") when any of the following conditions are true (when processing the memory_management_control_operation command equal to 3): there exists a non-paired reference base field (marked as "reference base picture") that is associated with one of the fields of the complementary reference field pair and that is marked as "used for reference", there exists a complementary reference base field pair (marked as "reference base picture") that is associated with the complementary reference field pair and in which one field is marked as "used for reference" and the other field is marked as "unused for reference". b) When decoding a field, the dec_ref_pi
