Criterion B Arts/Entertainment/Leisure

Criterion B
The in flight entertainment of the 21st century is consisted of major components such as Video Display Unit (VDU), Wireless router, Passengers/Personals control unit (PCU), Seat electronic box/unit (SEU) and operating system which acts as an interface between the users and the systems. Each aircrafts seat that can be classified as five star airlines has its own circuit and wiring which connects all the components together for the comfort of passengers.
The most essential component which provides power and energy to the system is known as the Seat Electronic Unit (SEU) and each of the components require their own seat electronic box. The Seat Electronic Boxes are consisted of cable Bundles that connect and transfer all the energy required for the systems to operate. These boxes are then connected to another power source which is controlled from another section where it is restricted to cabin crew and airline personnel only and this is where the (SEU) absorbs and consumes all the power that is needed to power the IFE system. Therefore, the Seat Electronic Unit acts as a hub for transferring power and electricity from the main source to the system through cable wiring. Electrical cables also are connected between seats creating a series circuit which can be switched off or on by the main switch (which is monitored by flight crew).
It then powers the Video Display Unit and Personal Control Unit. In an event of aircraft maintenance, the SEU contains line replaceable units (LRU) so malfunctioned electrical parts can be replaced without replacing the whole system with a new one. The VDU receives video and audio transmissions through wireless connections provided by the airline and the information that are sent and received between the two components are encrypted and designed to protect computer intruders to enhance the security while on board. Marvelous in flight entertainment layouts and are usually designed by companies that invest a lot in terms of providing operating systems. Corporations such as Panasonic Avionics, Thales and Linux are the main providers of IFEs for airliners like Emirates Airlines, Virgin, Etihad and Singapore Airlines. The Personal Control Unit (PCU) allows passengers and users to navigate through the system by using the Operating Systems and altering channels, audio volume and the brightness by using the PCU which also include the touch screen.
