Abstract

A circuit for receiving an image signal with a horizontal synchronization component at the horizontal scan frequency will produce a synchronization signal between the The middle that is synchronized with the synchronization component. Synchronize horizontally A linear deflection circuit produces a deflected current. The horizontal deflection that is synchronized with the synchronization signal in the middle of the oscillator generates the display lock signal. Synchronously with the clock signal that was born from the current Horizontal deviation The counter divides the said clock signal. Produces an output signal that can be decoded.The decoder circuit will provide Signal generator to lock the display timing At section frequency The synchronization is installed horizontally and at the intermediate signal frequency from the output of the horizontal counter. For example, by assembling two circuits that have been connected With counter and disconnect circuits The code contributes to the exact pulse of the display locking clock signal. To the extension of the video signal line in the video signal
