Abstract

A distribution system for vehicle information systems and methods for manufacturing and using same. The distribution system enhances the image quality of a conventional video display system via one or more video conversion systems. Each video conversion system receives information content via an incoming communication signal and enhances a video portion of the information content to form an enhanced video signal, which is provided to the video display system. By providing each video conversion system with a bypass system, the distribution system likewise can bypass one or more of the video conversion systems in the event of a distribution system failure such that communications among system resources can be maintained. As a result, passengers traveling aboard the vehicle can view information content with high resolution and high image quality during travel with limited interruption in service and without unwanted travel delays.
