reference base entry being a collective term for a non-paired reference base field, a reference base frame, or a complementary reference base field pair (marked as "reference base picture"): When one or more fields of a reference entry are marked as "used for reference" and there exists a reference base entry that is associated with the reference entry or one field of the reference entry and one or more fields of the reference base entry are marked as "used for reference", either all fields of the reference entry and the reference base entry that are marked as "used for reference" must be marked as "used for short-term reference" or all fields of the reference entry and the reference base entry that are marked as "used for reference" must be marked as "used for long-term reference". When these fields are marked as "used for long-term reference", the same value of long-term frame index must be assigned to all fields of the reference entry and the reference base entry that are marked as "used for reference". G.7.4.3.4 Slice header in scalable extension semantics Unless stated otherwise, for all references to clause 7.4.3 inside this clause, the following modifications apply. a) All referenced syntax elements and variables are syntax elements and variables for the dependency representation with dependency_id equal to the current value of dependency_id b) A frame, field, top field, bottom field, picture, and decoded picture is interpreted as layer frame, layer field, layer top field, layer bottom field, layer picture, and decoded layer picture, respectively, that represent an intermediate decoding result for the dependency representation with dependency_id equal to the current value of dependency_id An IDR picture is interpreted as layer picture with IdrPicFlag equal to 1 for the dependency representation with dependency_id equal to the current value of dependency_id d) An IDR access unit is interpreted as an access unit containing a primary coded picture with IdrPicFlag equal to 1 for the dependency representation w
