BACKGROUND1. Field of the Invention
The invention relates to systems for data servers and data communication networks related to aircraft in-flight entertainment and networking.
2. Description of the Related Art
Inflight entertainment (IFE) systems have evolved significantly over the last 25 years. Prior to 1978, IFE systems were typically audio systems. In 1978, Bell and Howell (Avicom Division) introduced a group viewing video system based on VHS tapes. Ten years later, in 1988, Airvision introduced the first inseat video system allowing passengers to choose between several channels of broadcast video. In 1997, Swissair installed the first interactive Video on Demand (VOD) system. Currently, several IFE systems provide VOD with full DVD-like controls.
Until about 2000, the pace at which capabilities were added to IFE systems outpaced the technological advances found in IFE systems, leading to heavier more costly systems. Since the early 00's, IFE suppliers have leveraged technological advances to moderately reduce the cost and size of IFE systems. However, significant drops in legacy IFE system costs are not easily realized, as these systems are implemented with proprietary hardware and software architectures created at significant development cost that must be amortized over a small group of buyers (namely, the airlines). Whereas a typical terrestrial VOD system may have tens of thousands of installations supporting tens of millions of end users, a typical IFE system may have only several hundred installations supporting tens of thousands of seats. The proprietary nature of current IFE systems typically leads airlines to deal exclusively with their installed IFE supplier for upgrades and modifications to the system. Because of the sole supplier nature of this relationship, the IFE supplier is able to extract premium fees for these services. This stands in contrast to the terrestrial VOD market, where most VOD systems are developed in an open architecture and conform to industry standards. This open architecture, standards-based environment has enabled many suppliers to enter the terrestrial VOD market and compete for each VOD hardware/software component, leading to significant price drops for terrestrial VOD systems.
In terrestrial VOD systems, the number of distinct hardware components encompassed in the end-to-end system can be quite large. Head-end components (VOD servers, system controllers, key managers, game servers, web servers, etc.) are typically mounted in standard racks, distribution components (Ethernet switches, ATM switches, SONET switches, etc.) are spatially distributed from the head end out to the viewing room, and within the viewing room there is typically a set top box and video display unit (VDU). Except for the set top box and in some cases the VOD server, terrestrial VOD system hardware components are commercial off-the-shelf (COTS) products. Therefore, there is typically little development or operational cost penalty for having more hardware. Also, the operational cost of terrestrial VOD systems is minimally impacted by the size, weight, or power of the system.
In the IFE environment, on the other hand, operational costs are highly dependent on the weight and power of the IFE system. IFE installation costs and passenger comfort depend largely on the size and form factor of the IFE line replaceable units (LRUs). And an airline's IFE operation and maintenance costs depend largely on the number of distinct LRUs, both within a single aircraft and across an airline's entire fleet of aircraft.
On the right side of
In the rest of the system shown in
All of the known IFE systems that employ a terrestrial-like VOD architecture (head-end, distribution, seat-end), require head-end to area wiring, area to seat wiring, and seat to seat wiring. This wiring varies both across IFE vendors and even across a single IFE vendor's different IFE products. Due to the high cost incurred by airlines and airframe original equipment manufacturers (OEMs) to install numerous designs of IFE wiring, there have been attempts in the industry to standardize and future-proof portions of it. However, these attempts have had only limited success.
SUMMARYThese and other problems are solved by a modular, scalable, extensible, IFE system that leverages terrestrial VOD hardware and software advances, is implemented on avionics hardware, and is packaged to reduce the number of distinct IFE LRUs not only in a single aircraft but across an airline's entire fleet of aircraft (regional jets to jumbo jets).

This composite packing is denoted in
The data loader 102 provides the following types of services for the IFE system: media content updates (movies, audio, games, internet web pages, files, etc.), key updates, and transaction data transfers. The data loader 102 typically transfers data to and from the IFE system using one of the following mechanisms: removable disk or tape that is inserted into a DL installed on the aircraft, a portable disk drive or tape drive that is carried onboard and temporarily connected to the audio server 105 or the video server 104, a wireless LAN, or other wireless link. The data loader 102 typically connects to head-end switch 109 using the head-end network cables 120.

The cabin management terminal (CMT) 111 allows flight attendants to perform system management and administration functions for the IFE system such as: LRU reboot, video channel preview, flight attendant override, attendant call status, reading light status, bit interrogation and system test. The CMT 111 typically connects to the head-end switch 109 via the head-end network cables 120.
The passenger flight information system server (PFISS) 108 receives data from the aircraft navigation system and computes various flight information including time to destination, speed, altitude, outside air temperature, time at destination, aircraft location for display to passenger either in text form, or graphically such as a moving map display. The PFISS 108 typically connects to the head-end switch 109 via the head-end network cables 120.
The head-end switch/distribution system 109 interconnects one or more head-end data servers, data networks, and/or other systems on the head-end of the IFE system. The head end switch/distribution system 109 also connects to the area distribution boxes 110 through the head-end to area network cables 121.
The area distribution boxes (ADBs) 110 typically provide a distribution and signal regeneration function for connecting the head-end switch 109 to the passenger seat LRUs. Typically, the ADBs 110 connect to head-end switch 109 over head-end to area network cables 121 and to the SEB 112 within each seat column over an ADB-to-SEB network cable 122.

Because of this, in-seat electronics are often designed at the seat group level rather than at the seat level.
The Seat electronics boxes 112 are in-seat LRUs that are typically mounted under the seat and contain the network interface and the local processing unit for a seat group. Each of SEBs 112 typically supports three seats corresponding to the common three-seat seat groups. SEBs 112 are usually mounted under the middle seat of the seat group. Common in-seat implementations of an SEB are illustrated in
The video display unit 113 includes a display device (e.g. flat panel display) for viewing video content and navigating the IFE menu system. However, due to complaints about the size of SEBs 112 from airline passengers and advances in technology, IFE suppliers have recently begun migrating more of the electronics that were previously located in SEBs 112 to the VDUs 113 to reduce the size of SEBs 112.
