Abstract
A horizontal synchronization circuit uses a standard decoder to generate a stable first signal locked in frequency and phase to horizontal synchronizing pulses in a composite video signal. A waveshaping circuit reshapes the first signal to generate a second signal for input to a synchronizing circuit. The synchronizing circuit generates a higher-frequency third signal. A timing generator divides the frequency of the third signal to generate a fourth signal having the same frequency as the first and second signals, and a fifth signal having a higher frequency. The fourth signal is fed back to the synchronizing circuit, and can also be used for synchronization of video signal processing. The fifth signal can be used for horizontal scanning at a rate higher than the standard horizontal frequency.
