Abstract

A terminal data loading device on a mobile platform includes a media unit for receiving a transportable media element containing media data and outputting a media signal to a control processor unit. The control processor unit outputs an information signal to a wireline communication unit. The wireline communication unit outputs a wireline signal to a network on the mobile platform.
