Abstract

A method for controlling an in-flight entertainment (IFE) system using network protocols, such as TCP / IP, HTTP, or FTP. Control of a plurality of functions, including in-seat and broadcast audio and video, overhead reading light control, and flight attendant call, are implemented using a network client, a network server, and a network server program, each communicating with network protocols. The network client may be visible or invisible to a user of the in-flight entertainment system, depending on whether a web browser or a virtual web browser is used as a network client. The software for each line replaceable unit (LRU) may be designed, redesigned, or tested independently from other components within the IFE system. Particular functions of the IFE system can be made available only to particular parts of the IFE system, allowing different levels of access to the IFE system for different passenger classes.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This patent application is a continuation of copending U.S. patent application Ser. No. 10 / 145,464, filed May 14, 2002, now allowed, herein incorporated by reference in its entirety.FIELD OF THE INVENTION

[0002] The invention generally relates to computer networks, and more particularly relates to a system and method for controlling and operating an in-flight entertainment system using network protocols. BACKGROUND OF THE INVENTION

[0003] Most commercial aircraft today are equipped with an IFE system. Typically, an IFE system includes a plurality of computers, which are connected to provide various functions. These computers include, for example, audio / video head-end equipment, area distribution boxes, passenger service systems (PSS), and seat electronic boxes. In the modular environment of an aircraft, each of these computers is referred to as a line replaceable unit (“LRU”) since most are “line fit” on an assembly line when an aircraf...
