  • Process and device for synchronizing a reference signal with respect to a video signal
    Patent number: 7050111
    Abstract: A synchronization process may include detecting successive horizontal synchronization pulses of a video signal, and a phase comparison between the successive detected pulses and the successive transitions of the reference signal for controlling the oscillator of the phase-locked loop. The detection of each horizontal synchronization pulse may include sampling the video signal, low-pass filtering the sampled signal, thresholding the filtered signal for leaving pulses having a level below a threshold. The synchronization process may also include selecting, as a function of predetermined selection criteria, from among the residual pulses within an observation window centered on a transition of the reference signal for the one which corresponds to the horizontal synchronization pulse.

  • Method and device for detecting the parity of successive fields of an interlaced video signal
    Patent number: 7023489
    Abstract: Successive values of a horizontal phase of a video signal are determined a predetermined integer number of video lines after the successive occurrences of vertical synchronization pulses. The successive values of a parity bit are updated according to the successive values of the horizontal phase. Indications on the parity of the fields are provided from the successive values of the parity bit.

  • System and method for detecting the nature of a video signal
    Publication number: 20030108332
    Abstract: A system and method for detecting the nature of a video signal using a video synchronization circuit including a phase locked loop having a time constant is disclosed. The method includes calculating a horizontal phase difference between a predetermined first line of the video signal and a predetermined second line of the video signal, the predetermined first line and the predetermined second line bracketing a change of frame. If the horizontal phase difference is greater than a threshold, the video signal is deemed to be a video recorder signal. The method further includes adjusting the time constant of the phase locked loop of the video synchronization circuit according to the nature of the video signal, as determined in the calculating step.
