ABSTRACT:
The present invention provides a synchronizing signal separation. In accordance with the present invention, a sync pulse processing circuitry slices a video signal and senses the peaks of the synchronizing pulse. A reference generating circuitry divides the output from the sync pulse processing circuitry into a plurality of reference signals that are compared with the video signal, thereby producing logic level outputs. A sync restoring circuitry combines the logic level outputs to provide precisely reconstructed synchronizing pulses of the video signal. The present invention incorporates different standard functions with superior performance because it may be applied for different types of video signals.
