Abstract: The improved landscape camera system for use in aircraft utilizes digital video technology to obtain multiple fields of view that are selectable for viewing by passengers on the aircraft, from either a single video frame or from multiple cameras with different fields of view. The camera module can also receive video input from one or more auxiliary video cameras, such as a vertical fin mounted video camera, i.e. directed forward for a view of the aircraft in flight, or a rearward looking belly mounted camera.

Abstract: A detection system is provided in a helical scan video tape recorder to detect guard band interference signals at low video tape speeds and for generating control pulses in response thereto which may be used by editing control systems, and the like, for counting frames on the video tape, and for indicating the direction of tape motion at such low tape speeds to enable the editing control system to control the operation of the video tape recorder in the vicinity of a selected edit frame in order that appropriate editing of the video tape may be achieved.

Abstract: A modular expandable, microprocessor controlled, editing control system is provided for on-line or off-line editing of a cassette or open-reel helical scan-type video tape recorder, or the like. Tape-to-tape editing is carried out by transferring selected video information from a "source" video tape recorder (VTR) to a "record" video tape recorder (VTR). The system includes microprocessor controlled solid state electronic control circuitry for the source and record video tape recorders, with a manually operated joystick which permits forward and reverse motion of the tapes in the recorders for the precise selection of the edit frames. The system is designed to control one source video tape recorder and one record video tape recorder, in its basic configuration, using standard control track pulses for edit cycle accuracy.

Abstract: A control system is provided which is capable of controlling the speed of a video tape recorder in a continuously variable manner, even though the video tape recorder is designed to operate at discrete speeds. The variable speed control is achieved without any need to modify the discrete speed video tape recorder. The control system of the invention selects two of the discrete speeds of the video tape recorder, and then switches between the two speeds at a rate determined by the setting of a variable speed control, so as to enable the video tape recorder to operate at variable speeds between the lower and the higher of the selected discrete speeds, and depending upon the setting of the variable speed control.
