Abstract: An aircraft in-flight entertainment system preferably includes, in one embodiment, a satellite TV receiver, at least one passenger video display connected to the receiver, and a processor connected to the receiver for determining an undesired condition and for generating a substitute image on the passenger video display rather than permit display of an undesired image which would otherwise be produced. The undesired condition may relate to a weak signal or component malfunction. Accordingly, the undesired image may be an undesired default text message or a degraded picture image. Other embodiments of the in-flight entertainment system are directed to providing a moving map image flight information channel integrated with the programming channels of the system.

Abstract: An aircraft in-flight entertainment system includes a satellite TV receiver, at least one video display connected to the receiver, and a multi-beam antenna on the aircraft for receiving signals from a plurality of satellite TV transponders. The multi-beam antenna may have right-hand circularly polarized (RHCP) and left-hand circularly polarized (LHCP) beams offset from one another by a beam offset angle. The beam offset angle may be less than an angle defined by the spacing of the DBS transponders. The system may also include an antenna steering positioner connected to the multi-beam antenna, and an antenna steering controller for steering the multi-beam antenna based upon received signals from at least one of the RHCP and LHCP beams. The antenna steering controller may comprise a processor for steering the multi-beam antenna based on a selected master one of the RHCP and LHCP beams and slaving the other beam therefrom.

Abstract: A method for installing and operating an aircraft in-flight entertainment system preferably includes installing an entertainment source on the aircraft; installing spaced apart signal distribution devices, each generating audio signals for at least one passenger in an audio-only mode, and generating audio and video signals to at least one passenger in an audio/video mode; installing a cable network connecting the entertainment source to the signal distribution devices; and operating the aircraft in-flight entertainment system with at least one predetermined signal distribution device in the audio-only mode. In addition, the method preferably includes later upgrading the aircraft in-flight entertainment system by connecting at least one passenger video display to the at least one predetermined signal distribution device to operate in the audio/video mode and while leaving the cable network unchanged.

Abstract: An aircraft in-flight entertainment system includes an antenna, a satellite TV receiver connected to the antenna, at least one video display connected to the satellite TV receiver, and wherein the antenna is steered using received signals from the relatively wide bandwidth from at least one satellite TV transponder, such as a direct broadcast satellite (DBS) transponder. The system may include an antenna steering positioner connected to the antenna, and an antenna steering controller comprising the received signal detector for generating a received signal strength feedback signal based upon signals from the at least one satellite TV transponder. A processor may be connected to the detector for controlling the antenna steering positioner during aircraft flight and based upon the received signal strength feedback signal. The antenna steering controller may further comprise at least one inertial rate sensor, and the processor may calibrate the sensor based upon the received signal strength feedback signal.
