ABSTRACT:
A universal vertical countdown and method for a video display is provided which will handle all standard vertical signals and systems while giving the same noise performance as a self-locking system. Control of the resetting of the countdown during the acquisition phase enables the use of a single set of storage elements to provide all major decodes necessary for the system.
