Frequent travellers nowadays are accustomed to in-flight entertainment. The history of IFE dates back to the very beginning of air travel, when commercial aviation spread around the world. IFE provides passengers with a variety of  onboard entertainment. The majority of wide-body aircrafts, suitable for long-haul flights, mostly use an AVOD (Audio Video On Demand) system, while medium-sized aircrafts often install a personal TV on the first and business class, while six passengers share a screen in economy. In the AVOD server, there is a large amount of programs, therefore each seatback screen can be easily compared to a networking computer, allowing passengers to enjoy hundreds of movies, thousands of songs and dozens of games on each aircraft. To improve their services, airlines attach a great importance to multilingual services in their entertainment systems, targeting passengers from all over the world.


The above data explains the real capacity of AVOD. Concerning in-flight connectivity, globally covered satellite communication systems enabled a communication chain between air and ground. This technology is already available on the North American territory and it is developing in the East Asian region as well. Passengers can log in to their IFE server and freely watch, chat, play games or do other social activities through their PED or through one provided by the airlines.
