ABSTRACT:
Apparatus for providing visible video information has equipment for providing electrical video information including picture signals and picture synchronizing signals affected by flutter, and equipment for processing synchronizing signals. This processing equipment effects a stabilization of synchronizing signals against at least part of the mentioned flutter. Equipment is connected to the video information providing equipment and to the synchronizing signal processing equipment for displaying video information contained in the picture signals. This displaying equipment effects synchronization of the video information with the processed synchronizing signals. Equipment is connected between a video information providing equipment and the synchronizing signal processing equipment for compensating the stabilizing function of the mentioned stabilization, whereby the displayed video information is synchronized with synchronizing signals affected by essentially the same flutter as the picture signals.
A method of improving the display of video information contained in video signals affected by flutter and synchronized by synchronizing signals subjected to processing by means for stabilizing synchronizing signals against at least part of the flutter, compensates the stabilizing function to preserve flutter in the synchronizing signals, and synchronizes the video signals for the display of video informaton by synchronizing signals affected by essentially the same flutter as the picture signals.
