ABSTRACT:
An improved high-performance vertical sync separator which can reliably operate during high frequency and non-standard video signal conditions and that utilizes a device-independent methodology. The synch separator includes a signal separator circuit having an input port for receiving a composite signal. A measuring device connected to the input port measures a first and second characteristic of the composite signal. A processor receives and compares the first and second characteristics, and recovers a vertical sync signal from the composite signal.
