Video technical systems based on graphical user elements with integrated operating elements for controlling storage and reproduction of data, are now processed in the studio using PCs or workstations for viewing and cutting the video material, but access to individual images of the video material is time consuming, for many users, mainly resulting from the use of software control of the screen menus. To simplify the processes in the system, a control device is provided and generates a control signal with a given event on the graphical user-surface (GUI) and is used for driving a corresponding operating element, which outputs to the user a perceptible check-back signal.
