DurFloors object
DurFloors sets a price floor for one range of creative durations, so a 15 second spot and a 60 second spot in the same slot can carry different floors. Arrays of them sit at imp.video.durfloors, imp.audio.durfloors, and imp.pmp.deals.durfloors. Added in OpenRTB 2.6-202309.
How it is used
The spec puts no constraints on the ranges and does not promise they avoid overlapping; when two ranges match one creative, buyer and seller decide between themselves which floor applies. A creative whose length falls outside every range is priced against Imp.bidfloor. On the Imp, these floors use the currency in Imp.bidfloorcur.
The Bid floors page covers it in more depth.
