a typical installation, the aircraft will have a docking station in each seatback, allowing the airline to fine-tune its IFE provision by installing eDVPs in any seat, zone or cabin, on the ground or in flight. Airline staff will be able to add or remove the eDVP in less than a minute, using a simple security installation tool that will be small enough to fit on a key-ring but complex enough to discourage theft. A quick-disconnect system will allow cabin crew to easily remove and replace defective units in flight.
