Abstract

A vehicle information system for passenger vehicles, such as automobiles and aircraft, and methods for manufacturing and using same. The vehicle information system includes a multi-regional antenna subsystem and a multi-regional receiver system for receiving viewing content provided by diverse content sources during travel, including international travel. The multi-regional antenna and receiver system provide selected viewing content for distribution throughout the vehicle information system and presentation via one or more passenger interfaces. As the vehicle approaches the coverage region of a selected content source, the vehicle information system automatically reconfigures the multi-regional antenna and receiver system to receive viewing content from the content source without requiring manual adjustment to, or replacement of, the multi-regional antenna subsystem and/or receiver system. Passengers traveling aboard the vehicle thereby can continuously enjoy the viewing content during travel with limited interruption in service and without unwanted travel delays.
