A Demand item represents the source of a video ad to be played in a Supply item. There are four types of Demand items – VAST, RTB, Prebid or CedatoX.

A single Demand item can be assigned to multiple Supply items.

The Demand item is chosen based on Cedato’s intelligent predictive algorithm (that maximizes yield optimization) and takes the logical preferences and the limitations set by the user into consideration (as defined in the Cedato user interface).
