The present application takes precedence arising from provisional application U.S. No. 61/273584 "SERIES-NETWORK in-FLIGHT ENTERTAINMENT SYSTEM WITH SIGNAL TRANSMISSION VIA optical FIBER TO the SEAT", filed August 6, 2009, and provisional application U.S. No. 61/274726, NETWORK MANAGEMENT SERIES-NETWORK in-FLIGHT ENTERTAINMENT SYSTEMS WITH SIGNAL TRANSMISSION VIA optical FIBER TO the SEAT", filed August 20, 2009, the contents of which are fully incorporated into the present application by reference. The technical field TO WHICH the INVENTION RELATES

In-flight entertainment system has received in the last 25 years considerable development. Until 1978 flight entertainment system consisted only of audio. In 1978 the company "bell & Howell" (OU "Evic" (Avicom)) implemented a group viewing video system based on video cassette. In 1988, the company "Allign" (Airvision) introduced the first built-in seat video system, allowing passengers to choose between multiple broadcast video channels. In 1997, the company "the Swissair-led" (Swissair) established the first interactive video-on-demand (video on demand, VOD). Currently, several of the upland entertainment systems provide VOD with full digital imitation selection of DVDs.

One of the factors the commercial viability �uletnoy entertainment system are interchangeable linear blocks (RBS) system. The term "RBS" is a professional term to describe a complex node (e.g., "black box") on the aircraft, which is designed for quick replacement on the route of flight or in the airport car parks. RBS is advantageous to use, as they are usually self-contained units that can be quickly replaced in the event repair is needed, which allows the aircraft to fly with minimal downtime. For installation on aircraft design RBS must first be approved by the Federal aviation administration pursuant to part 14 of the Code of Federal regulations. In RBS with a single instrument configuration can be installed different software. The cost of installing in-flight entertainment system, its operation, maintenance and repair, as well as the comfort of passengers, largely depend on the size, design parameters, number and weight RBS, and the number of RBS types that are installed on individual aircraft and fleets of aircraft of a particular company.

Fig.1 shows a conventional flight entertainment system, which applied the VOD architecture that simulates the ground system (i.e., head (distribution) node, areal distribution, the node of the seat). On the left side figurka shows the components normally found in the head node of the system or in the avionics Bay. N� the right side figurka shows the components that usually located in the node of the seat system. On the right side figurka shows the components normally found in habitat distribution between the head node and the node of the seat. These components include areal distribution boxes (ARC), which distributes data from the head node to the nodes of the seat. The ARC usually connected to e-boxes of seats (EX) for each vertical row of chairs, which in turn distribute the data forward and/or backward to adjacent groups of chairs in the same vertical row.

Suppliers of in-flight entertainment systems have recently made an attempt to reduce the number of RBS types on the nodes of the seats. Fig.1 shows four examples of normal architecture of the node of the seat. Fields A and D depict the traditional architecture types of seats, in which the FORMER are placed between the ARC and node components of the seat, such as a visual display device (SVR) and control panel passenger (RSP). Fields b and C depict more new types of architecture seats that reflect attempts to eliminate or reduce the dependence on the FORMER by transferring their functions SVR and/or navel. This transfer usually occurs by increasing the size, weight and power of the SVR and/or navel.

The developers of onboard entertainment systems, however, are not so quickly reduced the number of type�in RBS nodes in the head and in the area of distribution. In addition, conventional flight entertainment systems require nearealiai wiring and the wiring between the seats, which differs from one supplier-flight entertainment systems to another, and even between different flight entertainment systems of the same vendor, which increases the cost of installation and maintenance.

Some small players in the industry production flight entertainment systems have made progress in the head part and in the area of distribution. For example, one of the latest in-flight entertainment system has no head node, nor of the range of the distribution. However, this system has no analogues in terrestrial VOD systems and cannot be applied effectively to the achievement and development of ground systems. The newest in-flight entertainment system has simplified the head node, which combines servers audio, video and computer programs in a single RBS. However, this system is highly specialized and cannot be applied effectively to the achievement and development of ground-based VOD systems. Moreover, the latter system also requires a network of intermediate nodes in the area of distribution between the head node and the node of the seat.

A BRIEF SUMMARY of the INVENTION

System of data transmission via optical fiber to the seat (FTTS), described in published�bath patent application U.S. No. 2007/0077998, the contents of which are incorporated in this application by reference, and which is illustrated in Fig.2, offers a more modular, scalable, scalable, taking into account trends in the development of this area, wired in-flight entertainment system, which is able to effectively use land developments in the field of hardware and software VOD, and are configured so as to minimize the number of RBS types not only on a single plane, but in the entire fleet (i.e., from regional jets to Airbus). However, this system FTTS has certain disadvantages. First, each server-side switching device (SPU) is a single point of failure for all HEIs and all control terminals salon (TUS) which are connected directly in this SPU. Secondly, a variant of the star topology network in which each division is equipped with its own straight fiber-optic cables to a main SPU, makes the system more expensive and complicated. For example, to install the system on a standard narrow-body aircraft more than two miles of optical fiber, and the standard wide-body aircraft - more than four miles of optical fiber. The high cost of aviation varieties of optical fiber and fiber optic connectors, coupled with the cost � the complexity of installation of these components, make this architecture very expensive in execution.

DETAILED DESCRIPTION of PREFERRED VARIANTS

Fig.3 shows the in-flight entertainment system (PRS) with trains-network replacement linear units (PS-RBS) 311-313 ring and head replaceable linear blocks (RBS) 310, in some embodiments of the invention. As shown, chain PS-311 RBS and the ring G-RBS 310 are located outside of seats, while the chains of PS-RBS 312, 313 are located on the chairs. In these embodiments of the invention, several GSLB 309 physically connected in a ring via fiber-optic links 308. Several chains of PS-RBS 301 to 305 is physically connected to G-RBS 309 on their edges (ends) through the links 307, for example, fiber-optic, so that the two ends of each chain are physically connected to different G-RBS 309. You can use many types of PS-RBS, for example a series-network built-in network interface unit 301, a series-network external network interface unit 302, a series-network storage medium 303, consistently-TUS network 304 (usually installed in the kitchen block plane), and a series-network SVR 305.

Each PS-RBS 301 to 305 detects, by means of topological messages, the closest G-RBS 309. In the illustrated embodiment of the invention, starting at one end of the chain PS-311 RBS, unit 301 is connected to one of MR. RBS 309 via link 307 in an upward direction, the connecting unit 302 in a downward direction through another link 306. Unit 301 receives from G-RBS 309 in an upward direction message about the presence and the message of the presence, including the number of transitions to G-RBS 309, embeds a number of transitions, and sends the updated message about the presence further in the downward direction at block 302. As you move the reported presence in the downward direction, each subsequent PS-RBS in the chain (e.g., 302, 303, 304) embeds a number of transitions. If you continue to consider athapattu, the block 302 is coupled in a downward direction to a storage medium 303 via another link 306. The storage medium 303 is connected downstream from MYC 304 via another link 306. In the latter part of this chain of PS-311 RBS, TUS 304 on the edge of the chain is connected in reverse with the block G-RBS 309 via another link 307. In the other direction, TUS 304 receives from G-RBS 309 message about the presence, including the number of transitions that embeds a number of transitions, and sends the updated message about the presence in the upward direction to the storage medium 303. Each subsequent PS-RBS in the chain 311 embeds accordingly, the number of transitions.

In-flight entertainment system may have at least one additional chain PS-312 RBS, and possibly at least two additional chains of PS-RBS 312, 313. Additional chain or chains of PS-RBS 312, 313 can be made from almost any types of PS-RBS such as SVR 305. On each edge of such additional chains of PS-RBS 312, 313, one of a series-network SVR 305 is connected to one G-RBS 309 through the link, and within each chain PS-RBS sequence network SVR 305 are connected through links. These additional chains of PS-RBS 312, 313 are usually spread messages about the presence and the number of transitions in the same way as that previously described chain SS-311 RBS.

Separately each G-�B determines through topological messages, closed or open ring G-RBS 310. Every G-RBS 309 receives a message about the presence of neighboring G-RBS 309 and transmits this message about the presence on non-input port until then, until it is determined whether to return a message about the presence of generating his G-RBS 309 - in this case, it is found that the ring of G-RBS 310 is closed; or it is not generating returns to his G-RBS 309 - in this case, it is found that the ring of G-RBS 310 "disconnected".

Functional servers (e.g., the server software applications, audioserver, video server, game server, file server, server of the passenger information system) integrated in G-RBS 309 on a modular principle, with the possibility of scaling the system, and reliably, minimizing the impact on in-flight entertainment system in the case of one or more faults G-RBS 309. Processors network management in G-RBS and PS 309-RBS restore network access active PS-RBS 301 to 305 to MR. RBS 309 in the following scenarios: (a) disconnect the connection in the chain of PS-RBS 311-313; (b) the failure of SS-RBS 301 to 305 in the chain of PS-RBS 311-313; (C) the failure of MR. RBS 309 at one end of the chain PS-RBS 311-313. In addition, the processor network management in G-RBS 309 restore network access PS-RBS 301 to 305 as described with reference to Fig.6A-7D, the active G-RBS 309 in the following scenarios: (a) disconnect the connection between any TLD�I G-RBS 309; (b) the failure of MR. RBS 309. Although the number of PS-RBS 301 to 305 in the chain of PS-RBS 311-313 may vary, relatively short chain PS-RBS usually have a higher level of fault tolerance and increased bandwidth to the SS-RBS. In some embodiments, there are signs of errors, e.g. error codes, to facilitate detection, diagnosis and/or tracking errors. In some embodiments, the error pointers are passed to an external system for monitoring and/or maintenance.

Fig.4 shows a typical G-RBS 400 adapted for use in flight entertainment system, with chains of PS-RBS and ring G-RBS, in some embodiments of the invention. In such embodiments of the invention, G-RBS 400 is integrated servers in six different types, including one or more server software applications 401, video servers 402, audioserver 403, the game server 404, file servers 405 and server systems, to inform passengers 406, all of which are connected to the integrated processor network management 407 over internal connections. By way of example, the processor network management 407 may be a managed network switch.

The server software application 401 is network controllers that provide the following types of services: con�UNT-management; channel packaging; transaction processing; integration of the billing system; management services; software integration; administration and management; management of encryption key servers, authentication, etc.); manage software customers; integration of audio, video, gaming and file servers and the like. Video servers 402 provide the following types of services: VOD, "almost-VOD" (NVOD); pay-per-view (pay per view, PPV); network personal video recorder; video broadcasting and the like. Audioserver 403 provides the following types of services: audio-to-order; audio broadcasting, and the like. The game server 404 provides the following types of services: logic and programming for games; dynamic loading for games based on browsers and the like. File servers 405 provide the following types of services: caching of Internet content; caching the user data and profile information of the user, and the like. The servers of passenger information system 406 using the original data of the navigation system of the aircraft and calculate various types of information, including the time before boarding, speed, altitude, temperature outside, time at the destination airport, the location of an aircraft so that passengers could get either in text form or graphic, n�Ave, on the moving map, and the like.

The processor 407 TV has ports that are reserved for physically connecting to the PS-RBS at the edges of the chains, and K ports that are reserved for physical connection to other G-RBS in the ring. K ports that are reserved for ring connection G-RBS, is connected with the K G-RBS transceivers 408 (with ports), through internal connections. The transceivers 408, in turn, is connected to panel fiber optic coupling device 420 via K internal fiber optic connecting devices. Similarly, the N ports that are reserved for connections chain PS-RBS connected to N PS-RBS port transceivers 410 through internal connections. The transceivers 410, in turn, is connected to panel fiber optic coupling device 420 via N internal fiber optic connecting devices. In some embodiments, the inner fiber optic connectors are simplices by that time, when they are connected to the panel connection device 420 (e.g., port transceivers 408 and 410 are bidirectional, or coupler is used to convert the duplex unidirectional output signal of the bidirectional transceiver in simplex format). Plug patch panel�individual devices 420 docked with the coupling device 421, when MR. RBS 400 is mounted on the rack in the head part. The connecting device 421 has external fiber optic cables that are reserved for ports G-RBS, which are connected to corresponding internal fiber optic connectors G-RBS, when MR. RBS 400 is mounted on the rack. Similarly, the connecting device 421 has N external fiber optic cables that are reserved ports for chaining PS-RBS, which are connected to corresponding internal fiber optic connectors PS-RBS, when MR. RBS 400 is mounted on the rack. K and N are integers greater than one. In addition, MR. RBS 400 is T data ports, where K+N is a number less than or equal to T. Under the control of the CPU 407, G-RBS 400 provides information about the presence of any PS-RBS, which is connected directly with MR. RBS 400 via one of N external fiber optic cables that are reserved ports for chaining PS-RBS (i.e. any extreme PS-RBS). Under control of the processor 407, G-RBS 400 also provides information about the presence of any G-RBS, which is connected directly with MR. RBS 400 through one of the K external fiber optic cables that are reserved for ports D-RBS and passes on his no-input port of any information about the presence (which was not generated G-RBS) obtained on these p�mouths from neighboring G-RBS.

Fig.5 shows a typical PS-RBS 500 adapted for use in flight entertainment system, with chains of PS-RBS and ring G-RBS, in some embodiments of the invention. In these embodiments of the invention, PS-RBS 500 includes a core of RBS 501, consisting of instrument components and software, the first fiber optic transceiver 503, the second fiber optic transceiver 504 and the processor network management 502, which may be a managed network switch. The processor 502 is connected to the first communication transceiver 503 and the second transceiver 504 through the internal copper contacts. The processor 502 is connected to the communication core of RBS 501 via the internal connection, for example a copper contact. The first transceiver 503 is physically connected via, for example, an external fiber optic link with an ascending G-RBS or PS-RBS. The second transceiver 504 similarly physically connected through an external fiber-optic link with a descending G-RBS or PS-RBS. The processor 502 provides network access to kernel RBS 501 upstream G-RBS through the first transceiver 503 or downward to G-RBS via the second transceiver 504. Downward and upward directions were randomly assigned to a network routes the left and right of RBS, respectively.

Structure and functions of the kernel RBS 501 vary depending on the type PS-RBS. The core of CL� for the embedded network interface unit 301 provides access to audio data, passenger information and data with respect to passenger service, for example, management of light for reading, call steward, flight information for applications such as moving maps, etc. the Core of RBS for the external network interface unit 302 provides communication with ground-based networks, usually through satellite or terrestrial network of radio frequencies. This is the core of RBS can provide bidirectional or unidirectional communication depending on performance. Bidirectional versions provide connectivity with terrestrial networks (broadband connection). One-sided versions provide access to unborrowed sources of broadcast data such as television (broadcast video). The core of RBS for the media data 303 provides the ability to update media content (movies, audio, games, Internet sites, files, etc.), key update and transmission of transaction data. This is the core of RBS you can transfer data using one of the following mechanisms: a removable disk or tape, inserted into the storage medium 303, the portable drive or tape mechanism, onboard and temporarily connected to in-flight entertainment system, wireless LAN, or other wireless link. The core of RBS for TUS 304 allows the steward/stewardess to manage the system and to perform the functions of administreres�tion, such as: reboot RBS, preview video channels, locks, call status steward, status lamps, built-in test, test queries and systems. Kernel RBS for SVR 305 each include a physical display device (e.g., flat panel display), allowing passengers to view video content and search menu. Such kernel RBS can additionally provide the function of the EMP, such as volume control, channel switching, control of lighting, a steward call button, menu button and/or button, select menu, using the touch screen or mechanical buttons. Kernel for RBS interface modules displays (not shown) may include a physical interface to an external display device (e.g., flat panel display), which allows the passenger to view video content and search menu. As the kernel RBS for SVR, such kernel RBS can additionally provide the function of the EMP, such as volume control, channel switching, control of lighting, a steward call button, menu button and/or button, select menu, using the touch screen or mechanical buttons.

Fig.6A through 6D shows the maintenance of a series-network route data in some embodiments of the invention. Fig.6A shows the physical wiring of the flight enterta�an interesting system with a ring of four G-RBS and one chain of four PS-RBS, physically connected cable harness with G-RBS 1 and G-2 RBS. PS-RBS are informed about the nearest G-RBS through topological messages and regulate the participation of managers in a series-network routes data in order to establish and maintain basicallya routes the data with the smallest maximum number of network hops to any PS-RBS to one of the G-RBS. Fig.6B shows a series-network topology without any defects in the chain. The link between PS-RBS 2 and PS-3 RBS was removed from the route data, which led to the establishment of two bespelling routes data, and the maximum number of transitions to G-RBS is two. Fig.6C shows a series-network topology, the configuration of which was changed after the discovery that the link between PS-RBS 1 and PS-2 RBS failed. Such reconfiguration carried out by adding a link between PS-RBS 2 and PS-3 RBS to route data to ensure that all PS-RBS route data to G-RBS with the least number of hops; the maximum number of transitions to G-RBS is three. Fig.6D shows a series-network topology, the configuration of which was changed after the discovery, that the PS-4 RBS failed. Such reconfiguration carried out by adding a link between PS-RBS 2 and PS-3 RBS to route data to ensure that all PS-RBS, which estudiantine, route data to G-RBS with the least number of hops; the maximum number of transitions to G-RBS is three. These add and remove links, as shown in FIG.6 through 6D are performed under the control of the processor network management in the PS-RBS 1, PS-2 RBS and/or PS-3 RBS using information on the number of transitions and/or the presence of which is derived from the topological messages. For example, each PS-RBS may, under control of a processor network management, to determine whether the PS-average RBS in the chain, comparing the number of transitions received at both of its ports. If the number of transitions on both ports is the same or differs only by one transition, then the PS-RBS samoidentifitsirovalis as average RBS; otherwise, the PS-RBS not samoidentifitsirovalis as average RBS. If PS-RBS samoidentifitsirovalis as average RBS, PS-RBS breaks the chain to create besplainoe network topology. If the number of transitions on both ports differs only on one transition, PS-RBS under control of a processor network management blocks the port with a higher number of transitions (i.e., a port that has a longer route to the nearest G-RBS) and unlocks a different port. If the number of transitions on both ports is the same, the PS-RBS under control of a processor network management blocks pre�on assigned port and unlocks the second port.

Fig.7A through 7D shows the maintenance of cerebral route data in some embodiments of the invention. Fig.7A shows the physical wiring in-flight entertainment system with a ring of four G-RBS and one chain of four PS-RBS, physical (cables) connected to G-RBS 1 and G-2 RBS. When MR. find RBS closed ring G-RBS as a result of topological messages designed G-RBS removes one of its links from the route data to create bespelling route data between MR. RBS, and this link may be subsequently restored in the route data to maintain route data in the event of a failure of one of MR. RBS or links. Fig.7 shows the head of the network topology after discovery loop G-RBS. In this topology, the link between G-RBS 1 and G-4 RBS was removed from the route data to eliminate loops. Fig.7C shows the head of the network topology, the configuration of which was changed after the discovery that the link between G-RBS 3 and G-4 RBS failed. It is the link between G-RBS 1 and G-4 RBS was restored in the route data to maintain network access to all G-RBS. Fig.7D shows the head of the network topology, the configuration of which was changed after the discovery that G-2 RBS failed. Such a reconfiguration similarly led to the restoration of the link between HSV 1 and G-4 RBS in the route data to maintain network access to all active G-RBS. These add and remove links, as shown in Fig.7 through 7D are performed under the control of the processor network management in G-RBS 1, G-RBS-3, and/or G-4 RBS by using the information about the loops drawn from topological messages. In some embodiments, at least two of G-RBS in the ring MR. RBS have a single instrument configuration.

In some embodiments, the links are added or removed from trails data dynamic regulation of the status of the transceivers in G-RBS and PS-RBS between the shipment status data and status data block under the control of the processor network management.
