_operation equal to 5, all reference pictures in the DPB are marked as "unused for reference". Otherwise (the slice header of the current picture does not include memory_management_control_operation equal to 5), the decoded reference picture marking process specified in clause 8.2.5 is invoked when a coded video sequence conforming to one or more of the profiles specified in Annex A is decoded by applying the decoding process specified in clauses 2-9, or the decoded reference picture marking process specified in clause G.8.2.4 is invoked when a coded video sequence conforming to one or more of the profiles specified in Annex G is decoded by applying the decoding process specified in Annex G, or the decoded reference picture marking process specified in clause H.8.3 is invoked when a coded video sequence conforming to one or more of the profiles specified in Annex H is decoded by applying the decoding process specified in Annex H. All pictures m in the DPB, for which all of the following conditions are true, are removed from the DPB: picture m is marked as "unused for reference" or picture m is a non-reference picture. When a picture is a reference frame, it is considered to be marked as "unused for reference" only when both of its fields have been marked as "unused for reference", picture m is marked as "non-existing" or it has OutputFlag equal to 0 or its DPB output time to,dpb( m) is less than or equal to the CPB removal time t,(n) of the current picture n. When a frame or the last field in a frame buffer is removed from the DPB, the DPB fullness is decremented by one. C.2.4 Current decoded picture marking and storage When the decoding process specified in Annex H is applied, the process specified in this clause is invoked for a particular view with view order index VOIdx, with "picture" being replaced by "view component", "frame" being replaced by "frame view component", and "field" being replaced by "field view component". In clause C.2.4.2, the DPB output time to,dpb(n) and the CPB removal time t,(n) of a vi
