Aircraft communications system with video file library and associated methods

摘要

A video file system for an aircraft carrying a person having a personal electronic device (PED) for displaying video files includes a ground-based video server and an aircraft-based video system. The ground-based video server stores video files, with each video file being updatable from an available status to an unavailable status. The aircraft-based video system copies video files from the ground-based video server while the aircraft is on the ground. A determination is made, via communications with the ground-based video server and while the aircraft is on the ground, whether a given video file has been updated from the available status to the unavailable status. The PED is permitted to display the given video file if it has the available status, and is not permitted to display the given video file if it has the unavailable status.
