  • VERTICAL SYNC SIGNAL SEPARATION APPARATUS AND METHOD THEREOF
    Publication number: 20120188449
    Abstract: Vertical sync signal separation apparatus and method are provided. The vertical sync signal separation apparatus includes a parameter detecting unit, a threshold generating unit and a vertical sync signal generating unit. The parameter detecting unit measures a composite sync signal to obtain a maximum and a second maximum positive pulse width, and a maximum and a second maximum negative pulse width. The threshold generating unit outputs a positive pulse threshold based on the maximum and second maximum positive pulse width, and outputs a negative pulse threshold based on the maximum and second maximum negative pulse width. The vertical sync signal generating unit outputs a vertical sync signal by comparing the composite sync signal against the positive pulse threshold and the negative pulse threshold. As such, this apparatus can correctly separate a vertical sync signal from composite sync signals with different standards, thus increasing its supportability.
