A circuit for generating vertical and horizontal sync signals suitable for a display which is driven by digital signals, e.g. a liquid crystal display panel of a television receiver, whereby purely digital circuit elements can be utilized throughout, as opposed to conventional sync signal generating circuits which are basically of analog type. Recognition of sync signal components derived from a composite video signal is based on time discrimination using counters and gate circuits, and the circuits can be substantially entirely implemented within a single low power-consumption integrated circuit, e.g. a CMOS IC.
