Abstract
A distribution system for vehicle information systems and methods for manufacturing and using same. The distribution system supports high-bandwidth communications among system resources via one or more active routing systems. Comprising a plurality of communication ports coupled via a high-speed switching system, each routing system transparently splits incoming communication signals received via an input communication port. The routing system thereby can provide the incoming communication to a plurality of output communication ports without effecting signal bandwidth. By providing each routing system with a bypass system, the distribution system likewise can bypass one or more of the high-speed switching system in the event of a distribution system failure such that communications among the system resources can be maintained. As a result, passengers traveling aboard the vehicle can enjoy high-speed access to viewing content during travel with limited interruption in service and without unwanted travel delays.
