Abstract: In an arrangement for processing video signals provided as interlaced video signals generated in the interlaced scanning mode, in which two fields constitute one frame, and/or as pseudo-interlaced video signals derived from non-interlaced video signals obtained by means of progressive scanning, flexible use of the arrangement with a minimal number of components for this arrangement is achieved in that at least one video signal-processing unit (1) is provided which receives at least an interlaced video signal or at least a pseudo-interlaced video signal and processes these video signals in dependence upon control data generated by means of a control unit (2), and in that a clock generator (4) is provided which controls the control unit (2) and/or the video signal-processing unit (1) in such a way that, when processing an interlaced video signal or a pseudo-interlaced video signal, possibly new control data are generated and/or taken into account as from the start of its next field or its next frame, respective

Abstract: In a video mixer (1) in which a video component of the video signal to be mixed and a mixing type are preselectable for performing a mixing operation on said video signal applied to the mixer (1), an additional external function on the video mixer can be controlled in that an additional external function is selectable at the video mixer (1), this function being selectable from predetermined additional external functions, and in that the video mixer (1) generates a control signal during a mixing operation for controlling a selected external function, this control signal changing from a first extreme value to a second extreme value in the course of the mixing operation and serving for controlling the selected external function, an initial value of a variable of the external function being assigned to the first extreme value of the control signal and a final value of the variable of the external function being assigned to the second extreme value of the control signal.

Abstract: In a video signal distribution device (1) having operating elements (14, 15) and a control device (13) for evaluating the operating state of the operating elements (14, 15) and for forming a video output signal from a multitude of video source signals (7, 19) in dependence upon the operating state, the video output signal being made available at an output (12) of the device, there is provided, for second and third utilizers, that the video signal distribution device (1) includes a storage device (13) for storing an assignment prescription for assigning at least a second operating state to each evaluated operating state, and that the control device (13) generates at least a second video output signal in conformity with the second operating state predetermined by the storage device, and makes this second video output signal available at at least a second output (24).
