Abstract
A system and method for communicating audio or video information using inductive magnetic coupling between first and second adjacent seats on a mobile platform. A transceiver at the first seat receives signals from an in-flight entertainment (IFE) system. The signals are passed to a transmitter subsystem that generates low power inductive magnetic energy which is received by a receiver subsystem located on the second seat. The energy is converted to electrical signals for generating an output signal to an audio jack associated with a personal control unit (PCU) at the second seat. The audio content can then be used at the second seat together with video content displayed on a video display unit at the first seat, without affecting the synchronization of the audio signals and the video signals.
