Abstract:
An inflight entertainment (IFE) system preloads from head end equipment onto seat end video caches subsets of prerecorded video entertainment programs from a library of prerecorded video entertainment programs stored on the head end equipment. Preloading is done independent of play requests made by passengers using the IFE system. The selected subsets are selected using selection metrics such as program popularity, passenger demographics and/or passenger preferences. The same or a different subset may be selected for different passengers. As a result of the selective preloading of the seat end video caches, if the head end equipment or the distribution system becomes inoperable during the flight, the IFE system is able to continue to deliver a limited offering of popular, demographically indicated and/or passenger preferred video entertainment from the seat end video caches, without requiring a large multiplier in storage capacity or loading time.
