摘要： A passenger aircraft video distribution system distributes modulated RF signals provided from a central signal source to be used at each passenger seat. The RF signals are distributed by means of various RF components, including amplifiers (90, 14a, 164, 24a, 24b, 34a), taps (180, 210) and splitters (108, 182, 214). In order to ensure proper RF levels for best tuner operation, each of a number of stations in the distribution system is provided with a variable gain amplifier (90, 14a, 164, 24a, 24b, 34a) controllable by a microprocessor (92, 50a, 220, 52a, 56a, 216). A separate service line (222, 224, 226, 228, 230, 232, 234) enables a central microprocessor to monitor RF levels at different stations to automatically provide, via the same service line, appropriate gain control signals to obtain proper RF levels. The monitored RF levels are also employed for diagnostic purposes.

摘要： A passenger aircraft video distribution system distributes modulated RF carrier signals from a central signal source (10) to be used at each passenger seat (S1, S2, S3). The carriers are modulated to contain both audio and video data (12,14) and also other digital data, such as graphics, slide shows and the like. Analog video signals (14) from the video source are modulated (100) on individually discrete carriers in the range of 54 to 300 megahertz. Audio information, including audio sound channels and the video audio, are digitized (80,84) and combined with digital data in a combined serial bit stream that is multiplexed (82), and then modulated (96) on an RF carrier having a frequency sufficiently above the frequency band of the video signals so that the resulting spectrum of the modulated audio RF carrier does not interfere with the modulated video carriers. The RF carrier signals are combined (104) and distributed to individual seats. The modulated audio carrier (112) is separated from the video carriers (110) at each seat or each group of seats and then demodulated (116) and demultiplexed (120) for selection at each individual seat of a chosen audio channel.

摘要： A passenger aircraft video distribution system distributes modulated RF signals (lines 16,26) provided from a central signal source to be used at each passenger seat (208-1 through 208-15). The RF signals are distributed by means of various RF components, including amplifiers (14, 24, 34), taps and splitters (22, 30), positioned at different mutually distant stations (12, 18, 28), with at least some stations being interconnected by relatively long lengths of coaxial cable (16,26). In order to ensure proper RF levels for best tuner (36) operation and to compensate for different cable losses at different frequencies, one or more of the stations (18) in the distribution system is provided with a variable equalizer (23) controllable by a microprocessor (52). A separate service line (64,66) enables a central microprocessor (50) to monitor RF levels at different frequencies at at least one station (28) to automatically provide, via the same service line, appropriate equalization control signals to obtain proper compensation for the different cable losses at different frequencies. The monitored RF signals are also employed for diagnostic purposes.

摘要： Systems that distribute live television programs to passengers of an aircraft by way of satellites of a direct broadcast satellite (DBS) system when the aircraft is in range of the satellites and distributes time-delayed television programs when the aircraft is out of range of the satellites. The present invention provides for real-time reception and storage of live television programs in a storage medium (in compressed digital format) and presentation to passengers during that time when the aircraft is within the coverage area of satellites. The stored programming is distributed to the passengers later in the flight, when the aircraft is out of range of the satellites. The stored programming includes all channels transmitted by the satellites. Thus, a large number of programs are made available to the passengers on a time-delay basis. A low-cost system is disclosed that distributes a single television channel to overhead monitors and headphones. A method of providing delayed distribution of television programs from satellites of a direct broadcast satellite system to passengers on an aircraft is also disclosed.

摘要： An intercom system that allows a flight attendant and passengers to communicate to each other to order and fill service requests, and allows the passengers to view the flight attendant at the same time by way of a display located at the passenger's seat. The flight attendant receives passenger service requests and communicates by way of a flight attendant control unit and handset that is typically located in a service galley. Passengers communicate by way of passenger control unit and handsets located at each seat. A camera mounted in the galley allows passengers to view the flight attendant while making the service request. Using the aircraft audio and video intercom system saves a flight attendant extra trips to seats to receive each service request. Using the present invention, the flight attendant can receive the request in the galley and immediately deliver the item to the passenger, thus providing faster service and response time and eliminating unnecessary trips.

摘要： The disclosure describes a moving receiver station capable of receiving broadcast entertainment signals from a first geostationary satellite associated with a first program provider, or from a second geostationary satellite associated with a second program provider. The receiver station is part of an aircraft and includes a tracking antenna and switching and control system that locks the tracking antenna on either the first or second satellite. The switching and control system receives position information, program attribute information and satellite coverage area information to determine when the aircraft is leaving one coverage area and entering another. The switching and control system switches the antenna to the second satellite when the aircraft enters the second coverage area, and limits the availability of received programming based on whether the aircraft is leaving the first coverage area or entering the second coverage area.

摘要： Each unit of a daisy chain of separate and independent multiplexing units (10,12,14) is arranged to accept a group of local audio inputs (Audio 1-Audio 8) and an additional input (18,20,22) from a prior unit in the chain to time division multiplex the additional input with the local units. Each unit provides a single serial bit stream output (20,22,24) which comprises the additional input to the next identical multiplexer unit in the chain. The next multiplexer unit time division multiplexes all of its inputs to provide a single output which includes a serial presentation of its own local inputs and the local inputs of the preceding multiplexer unit of the chain. This single serial output of the next multiplexer next forms the additional input of a still further multiplexer unit of the chain, which itself may have its own local inputs. The third multiplexer unit provides a single output that is a serial presentation of the local inputs of all three multiplexers. Additional multiplexer units can be added to the chain as may be necessary or desirable to accommodate reconfiguration of systems with which the multiplexers are used.
