Abstract

An airborne cell phone in-flight entertainment (IFE) system uses a cell phone for calls and IFE requests by dialing appropriate numbers. A pico cell receives the calls and the IFE requests. A soft switch switches the calls and IFE requests according to the telephone number. A transceiver receives the calls from the soft switch and sends them to a ground station that directs them to a telephone system. A media server receives IFE requests and provides IFE to the cell phone. A direct broadcast satellite (DBS) receiver on the aircraft receives DBS signals. A transcoder converts the received DBS signals from one compressed video format to another. A broad-to-connection protocol conversion process receives converted format DBS signals and converts them to video content blocks, stores the video content blocks to a continuously updated buffer and presents them to the media server and then to the cell phone.
