Method of distributing audio programming to passenger entertainment systems, and apparatus
First Claim
1. A method of distributing audio programs to passenger entertainment systems on-board a plurality of aircraft, comprising the steps of:
- providing audio data including a plurality of audio programs;
encoding said data to produce compressed digitally coded audio data;
storing said compressed digitally coded data onto a hard-disk array;
transmitting the stored compressed digitally coded data from a central facility for being received by a plurality of local facilities;
receiving the transmitted data by said local facilities;
storing the received data at said local facilities onto hard-disk arrays;
transmitting the locally stored data from said local facilities for being received by passenger entertainment systems on-board aircraft locally situated with respect to respective ones of said local facilities;
receiving the locally transmitted data by said passenger entertainment systems on-board said locally situated aircraft; and
storing the aircraft received data onto hard-disk arrays resident in said passenger entertainment systems.

Abstract
A method and apparatus for automating the distribution of audio programming to passenger entertainment systems on-board carriers such as aircraft. Audio signals containing the audio programming are encoded to produce compressed digital audio data signals, and the compressed digital data from the encoded signals are stored and subsequently distributed from a central distribution facility to a plurality of local distribution facilities located at or in the vicinity of airports. The compressed digital data is stored at each of the local distribution facilities, and is subsequently distributed to passenger entertainment systems on-board aircraft locally situated with respect to respective ones to the local distribution facilities. The aircraft received data is stored onto computer storage media, such as computer hard-disks, resident in the passenger entertainment systems on-board the aircraft.
