The Full Screen Video ad provides guests with the capability to launch a video element playing within an IAB ad unit into a full screen experience. Full screen capability is initiated by clicking on a standard display ad unit.  Closing the full screen experience must return guest to the page they were viewing previous to full screen initiation. This feature can be applied to both in-page and expandable rich media ad units.  Full Screen Video must be 3rd party served.
