Abstract
An in-flight entertainment system provides live video/audio programming to passengers and operators over an aircraft video/audio distribution system. The programming signals are derived from satellite broadcast signals that may be in either circular polarized form or linear polarized form. The broadcast signals are collected by two probes and extracted as right and left circular polarized signals. The right and left circular polarized signals are converted into either circular or linear polarized IF signals, and the IF signals are processed by a receiver/decoder unit to produce the live video/audio programming signals.
