Aircraft data management system

A data management system for supplying data to selected ones of identifiable seats comprising:

• (a) a plurality of data sources;
• (b) a least one power source;
• (c) an integrated seat box that is disposed proximate to a group of said identifiable seats, said integrated seat box being capable of converting at least one of said data and said power to a form useful to a passenger occupying one of said identifiable seats;
• (d) a data network interface module coupled to said integrated seat box, said data network interface module being fault tolerant such that a failure at one seat box does not interfere with the normal operation of successive data network interface modules, said data network interface module including a power distributing physical layer that is galvanically isolated from a data distributing microprocessor;
• (e) a network controller capable of managing said plurality of data sources;
• and
• (f) a seat-to-seat cable having therein data communication lines and power supply line whereby both data from said plurality of data sources and power from at least one power source are routed by said network controller to selected ones of said identifiable seats.
